These forward-looking statements may concern possible or anticipated future results of operations or business developments. These statements are based on management’s current expectations or predictions of future conditions, events or results based on various assumptions and management’s estimates of trends and economic factors in the markets in which we are active, as well as our business plans. Words such as “expects”, “anticipates”, “intends”, “plans”, “believes”, “seeks”, “estimates”, “projects”, “forecasts”, “may”, “should”, variations of such words and similar expressions are intended to identify such forward-looking statements. The forward-looking statements may include, without limitation, statements regarding product development, product potential, regulatory environment, sales and marketing strategies, capital resources, operating performance, or sales of common shares pursuant to this offering. Forward-looking statements include, but are not limited to, statements about:

	·	our expectations regarding the use of our existing capital resources and any proceeds we may receive from the sale of common shares offered under this prospectus;
	·	our efforts to pursue collaborations with other companies and third parties;
	·	our ability to maintain regulatory approval of our sole product, PEDMARK^® (known as PEDMARQSI^TM in the European Union);
	·	the benefits of the use of PEDMARK^®;
	·	our ability to successfully commercialize PEDMARK^®;
	·	the rate and degree of market acceptance of PEDMARK^®;
	·	our ability to maintain, or recognize the anticipated benefits of, orphan drug designation for PEDMARK^®;

The forward-looking statements are subject to risks and uncertainties, which may cause results to differ materially from those set forth in the statements. Forward-looking statements should be evaluated together with the many uncertainties that affect our business and our market, particularly those discussed under the “Risk Factors” section of this prospectus and any accompanying prospectus supplement and under “Risk Factors” in Item 1A of our most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and Item 1A of any subsequently filed Quarterly Reports on Form 10-Q, as such factors may be updated from time to time in our periodic filings with the SEC (which documents are incorporated by reference herein), as well as the other information contained or incorporated by reference in this prospectus.

FENNEC PHARMACEUTICALS INC.

This is only a summary and may not contain all the information that is important to you. You should carefully read both this prospectus and any accompanying prospectus supplement and any other offering materials, together with the additional information described under the heading “Where You Can Find More Information”. Unless otherwise noted, the terms “Fennec Pharmaceuticals”, “the Company,” “we,” “us,” and “our” refer to Fennec Pharmaceuticals Inc. and its wholly-owned subsidiaries.

We are a corporation existing under the laws of British Columbia. We are a commercial-stage biopharmaceutical company focused on our only product, PEDMARK^®. On September 20, 2022, we received approval from the U.S. Food and Drug Administration (“FDA”) for PEDMARK^® (sodium thiosulfate injection) to reduce the risk of ototoxicity associated with cisplatin in pediatric patients one month of age and older with localized, non-metastatic solid tumors. This approval makes PEDMARK^® the first and only treatment approved by the FDA in this area of unmet medical need. On October 17, 2022, we announced commercial availability of PEDMARK^® in the U.S. In addition, in January 2023, PEDMARK was included in the National Comprehensive Cancer Network (NCCN) clinical practice guidelines for Adolescent and Young Adult (AYA) Oncology with a category 2A recommendation.

In June 2023, we received European Commission Marketing Authorization for PEDMARQSI^TM (known as PEDMARK^® in the U.S.). Further, the decision included the receipt of a Pediatric Use Marketing Authorization (“PUMA”) in the European Union (“EU”) with up to 10 years of data and market protection. We are currently preparing for an EU launch of PEDMARQSI^TM in 2024.

In the U.S., we sell PEDMARK^® through an experienced field force including Regional Pediatric Oncology Specialists and medical science liaisons who are helping to educate the medical communities and patients about cisplatin induced ototoxicity and our programs supporting patient access to PEDMARK^®. Now that we have obtained applicable regulatory approval to sell PEDMARK^® in the U. S. and authorization from the European Commission Marketing Authorization for PEDMARQSI^TM in the EU, we recognize there may still be a need to establish collaborations that provide us with up-front payments, licensing fees, milestone payments, royalties, or other revenue.

During the three and nine months ended September 30, 2023, we incurred a loss from operations of $1.0 million and $11.0 million, respectively. At September 30, 2023, we had an accumulated deficit of $216.6 million and had experienced negative cash flows from operating activities during the nine months ended September 30, 2023 in the amount of $12.3 million.

RISK FACTORS

Investing in our common shares involves risks. In deciding whether to invest in our common shares, you should carefully consider the risk factors included in our Annual Report on Form 10-K for our fiscal year ended December 31, 2022, as well as any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, in addition to the other information contained in this prospectus supplement and the accompanying prospectus and the information incorporated by reference herein and therein. The risks and uncertainties described in our filings with the SEC are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, also may become important factors that affect us. If any of these risks occur, our business, financial condition or results of operations could be materially and adversely affected. In that case, the value of our common shares and your investment could decline. See “Forward-Looking Statements.”

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement, we intend to use the net proceeds from this offering for the continuation of commercialization efforts of PEDMARK^® in the United States, preparation for commercialization of PEDMARK^® outside of the United States, and general corporate purposes. We have not allocated the proceeds to these purposes as of the date of this prospectus. Allocation of the proceeds of a particular series of securities, or the principal reasons for the offering, if no allocation has been made, will be described in the applicable prospectus supplement.

DESCRIPTION OF CAPITAL STOCK

The following summary of the terms of our capital stock does not purport to be complete and is subject to and qualified in its entirety by reference to our Articles of Incorporation and our Bylaws, each of which may be further amended from time to time and both of which are incorporated herein by reference.

General

As of November 6, 2023, our authorized capital stock consists of an unlimited number of common shares, no par value per share, of which 26,709,469 common shares were issued and outstanding as of that date.

Common Shares

Pursuant to our Notice of Articles and Articles, as amended, we are authorized to issue an unlimited number of common shares, no par value. Each holder of a Share is entitled to one vote for each common share held on all matters submitted to a vote of shareholders. We have not provided for cumulative voting for the election of directors in our Notice of Articles or Articles, as amended. This means that the holders of a majority of the shares voted can elect all of the directors then standing for election. The holders of outstanding our common shares are entitled to receive dividends out of assets legally available at the times and in the amounts that our board of directors may determine from time to time.

Holders of common shares have no preemptive subscription, redemption or conversion rights or other subscription rights. Upon our liquidation, dissolution or winding-up, the holders of common shares are entitled to share in all assets remaining after payment of all liabilities. The rights of the holders of our common shares are subject to, and may be adversely affected by, the rights of holders of shares of any preferred stock that we may designate and issue in the future. Each outstanding common share is, and all common shares to be issued in this offering, when they are paid for, will be fully paid and non-assessable.

Computershare is the transfer agent for our common shares.

Our common shares are listed on the NASDAQ Capital Market under the symbol “FENC”.

Exchange Controls, Restrictions on Voting or Ownership

There is currently no law, governmental decree or regulation in Canada that restricts the export or import of capital, or which would affect the remittance of dividends, interest or other payments by us to a non-resident holder of our common shares, other than applicable tax requirements.

There is currently no limitation imposed by the laws of Canada or by our Notice of Articles or Articles on the right of a non-resident to hold or vote our common shares, other than those imposed by the Investment Canada Act and the Competition Act (Canada). These acts will generally not apply except where control of an existing Canadian business or company, which has Canadian assets or revenue over a certain threshold, is acquired and will not apply to trading generally of securities listed on a stock exchange. A reviewable acquisition may not proceed unless the relevant minister is satisfied that the investment is likely to be of net benefit to Canada.

Shareholders’ Rights Plan

The Company adopted a shareholder rights plan agreement (the “Rights Plan”) on June 27, 2017. The Rights Plan was adopted to ensure, to the extent possible, that all of our shareholders are treated fairly and equally in connection with any take-over bid or other acquisition of control. Generally stated, the Rights Plan is designed to address this purpose by requiring any potential transaction that will result in a person (an “Acquiring Person”) owning, in the aggregate, 20% or more of our outstanding common shares (inclusive of any common shares held by the Acquirer, its associates and affiliates, and any person acting jointly or in concert with any of them (collectively, the “Acquirer Group”)) to be structured as a formal take-over bid that satisfies certain minimum requirements relating primarily to the manner in which the bid must be made, the minimum number of days the bid must remain open, and the minimum number of shares that must be acquired under the bid. Non-compliant transactions may, through the operation of the Rights Plan and the rights issued thereunder, result in the Acquirer Group’s common share position in us being substantially diluted. Consequentially, the Rights Plan incentivizes the Acquirer to structure its proposed transaction in a manner that complies with the minimum requirements prescribed by the Rights Plan, thereby helping fulfill the purpose of the Rights Plan. One right (a “Right”) is issued and attached to each common share. This includes all common shares issued as of the effective date of the Rights Plan and all common shares issued after the effective date of the Rights Plan but prior to the eighth trading day after the earlier of public announcement of a take-over bid (other than a take-over bid that is a permitted bid or a competing permitted bid, as the case may be, under the Rights Plan) or the date upon which a permitted bid or competing permitted bid under the Rights Plan ceases to be such, or such later date as may be determined by our board of directors.

CERTAIN ERISA MATTERS

Unless otherwise indicated in the applicable prospectus supplement, the offered securities may, subject to certain legal restrictions, be held by (i) an “employee benefit plan” (as defined in Section 3(3) of the Employee Retirement Security Act of 1974, as amended (“ERISA”)) that is subject to Title I of ERISA, (ii) a “plan” as defined in, and subject to, Section 4975 of the Code or (iii) a “benefit plan investor” within the meaning of Section 3(42) of ERISA. A fiduciary of any such employee benefit plan, plan, or benefit plan investor must determine that the purchase, holding and disposition of an interest in such offered security is consistent with its fiduciary duties and will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code.

PLAN OF DISTRIBUTION

We may from time to time offer and sell some or all of the securities covered by this prospectus. Registration of securities covered by this prospectus does not mean, however, that those securities necessarily will be offered or sold.

The securities covered by this prospectus may be sold from time to time, at market prices prevailing at the time of sale, at prices related to market prices, at a fixed price or prices subject to change or at negotiated prices, by a variety of methods including the following:

on the NASDAQ Capital Market (including through at the market offerings);

in the over-the-counter market;

in privately negotiated transactions;

through broker/dealers, who may act as agents or principals;

through one or more underwriters on a firm commitment or best-efforts basis;

in a block trade in which a broker/dealer will attempt to sell a block of securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

through put or call option transactions relating to the securities;

directly to one or more purchasers;

through agents; or

in any combination of the above.

In effecting sales, brokers or dealers engaged by us may arrange for other brokers or dealers to participate. Broker/dealer transactions may include:

purchases of securities by a broker/dealer as principal and resales of the securities by the broker/dealer for its account pursuant to this prospectus;

ordinary brokerage transactions; or

transactions in which the broker/dealer solicits purchasers on a best efforts basis.

No securities covered by this prospectus will be offered or sold in Canada, including through the TSX or any other trading market in Canada, or to or from persons resident in any Province or Territory of Canada or to or from any person acquiring such securities for the benefit of another person resident in any Province or Territory of Canada.

At any time a particular offer of the securities covered by this prospectus is made, a revised prospectus or prospectus supplement, if required, will set forth the aggregate amount of securities covered by this prospectus being offered and the terms of the offering, including the name or names of any underwriters, dealers, brokers or agents. In addition, to the extent required, any discounts, commissions, concessions and other items constituting underwriters’ or agents’ compensation, as well as any discounts, commissions or concessions allowed or reallowed or paid to dealers, will be set forth in such revised prospectus supplement. Any such required prospectus supplement, and, if necessary, a post-effective amendment to the Registration Statement of which this prospectus is a part, will be filed with the SEC to reflect the disclosure of additional information with respect to the distribution of the securities covered by this prospectus.

To the extent required, the applicable prospectus supplement will set forth whether or not underwriters may over-allot or effect transactions that stabilize, maintain or otherwise affect the market price of the securities at levels above those that might otherwise prevail in the open market, including, for example, by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids.

If we utilize a dealer in the sale of the securities being offered pursuant to this prospectus, we will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

We may also authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the revised prospectus or prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The conditions to these contracts and the commission that we must pay for solicitation of these contracts will be described in a revised prospectus or prospectus supplement.

In connection with the sale of the securities covered by this prospectus through underwriters, underwriters may receive compensation in the form of underwriting discounts or commissions and may also receive commissions from purchasers of securities for whom they may act as agent. Underwriters may sell to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agent.

Any underwriters, broker/dealers or agents participating in the distribution of the securities covered by this prospectus may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions received by any of those underwriters, broker/dealers or agents may be deemed to be underwriting commissions under the Securities Act.

We may agree to indemnify underwriters, broker/dealers or agents against certain liabilities, including liabilities under the Securities Act, and may also agree to contribute to payments which the underwriters, broker/dealers or agents may be required to make.

Certain of the underwriters, broker/dealers or agents who may become involved in the sale of the securities may engage in transactions with and perform other services for us in the ordinary course of their business for which they receive customary compensation.

Some or all of the securities may be new issues of securities with no established trading market. Any underwriters that purchase the securities for public offering and sale may make a market in such securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We make no assurance as to the liquidity of or the trading markets for any securities.

LEGAL MATTERS

The validity of the securities offered hereby will be passed upon for us LaBarge Weinstein LLP, Ottawa, Ontario. Underwriters, dealers or agents, if any, who we identify in a prospectus supplement may have their own counsel pass upon certain legal matters in connection with the common shares offered under this prospectus.

In the event that any sales are made pursuant to the at the market offering agreement that are not made directly on the Nasdaq Capital Market or on any other existing U.S. trading market for our common shares at market prices at the time of sale, we will file a prospectus supplement describing the terms of such transaction, the amount of shares sold, the price thereof, the applicable compensation, and such other information as may be required pursuant to Rule 424 and Rule 430B of the Securities Act, as applicable, within the time required by Rule 424 of the Securities Act.

Prior to the effective date of the registration statement of which this prospectus supplement forms a part, the offer and sale of our common shares pursuant to the at the market offering agreement was made under a prior registration statement on Form S-3 (File No. 333-249775) and related prospectus supplement, each dated November 10, 2020, which we refer to in this prospectus as the prior prospectus. Upon the effective date of the registration statement of which this prospectus supplement forms a part, the offer and sale of our common shares pursuant to the at the market offering agreement will no longer be made under the prior prospectus, but will instead be offered and sold under this prospectus.

Our common shares are listed on the Nasdaq Capital Market under the symbol “FENC” and on the Toronto Stock Exchange under the symbol “FRX.” On November 6, 2023, the last reported sale price of our common shares on The Nasdaq Capital Market was $7.96 per share.

The sales agent will receive a commission of 3.0% of the gross sales price per common share sold through it as our sales agent under the at the market offering agreement. We have also agreed to reimburse certain expenses of the sales agent in connection with the at the market offering agreement as further described in the Plan of Distribution section of this prospectus supplement. Subject to the terms and conditions of the at the market offering agreement, the sales agent will use its commercially reasonable efforts to sell on our behalf any common shares to be offered by us under the at the market offering agreement. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. The offering of common shares pursuant to the at the market offering agreement will terminate upon the earlier of (i) the sale of all of our common shares provided for in this prospectus supplement or (ii) termination of the at the market offering agreement pursuant to its terms by either the sales agent or us.

Investing in our common shares involves a high degree of risk. Before buying any common shares, you should carefully consider the risks that we have described in “Risk Factors” beginning on page S-3 of this prospectus supplement, as well as those described in our filings under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

No common shares distributed under this prospectus supplement will be offered or sold in Canada, including through the TSX or any other trading market in Canada. See “Plan of Distribution” beginning on page S-6 of this prospectus supplement.

ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus relate to the sale of our common shares registered for sale under a registration statement that we filed with the Securities Exchange Commission (the “SEC”) utilizing a “shelf” registration process. This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this common share offering and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference herein and therein. The second part, the accompanying prospectus, provides more general information. Generally, when we refer to this prospectus, we are referring to both parts of this document combined. To the extent there is a conflict between the information contained in this prospectus supplement and the information contained in the accompanying prospectus or any document incorporated by reference therein filed prior to the date of this prospectus supplement, you should rely on the information in this prospectus supplement; provided that if any statement in one of these documents is inconsistent with a statement in another document having a later date — for example, a document incorporated by reference in the accompanying prospectus — the statement in the document having the later date modifies or supersedes the earlier statement.

We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to any document that is incorporated by reference herein were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreements, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were effective only as of the date when made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

Neither we nor the sales agent have authorized anyone to provide information different from that contained in this prospectus supplement and the accompanying prospectus, including any free writing prospectus that we have authorized for use in this offering. When you make a decision about whether to invest in our common shares, you should not rely upon any information other than the information in this prospectus supplement or the accompanying prospectus, including any free writing prospectus that we have authorized for use in this offering. Neither the delivery of this prospectus supplement or the accompanying prospectus, including any free writing prospectus that we have authorized for use in this offering, nor the sale of our common shares means that information contained in this prospectus supplement and the accompanying prospectus, including any free writing prospectus that we have authorized for use in this offering, is correct after their respective dates. It is important for you to read and consider all information contained in this prospectus supplement and the accompanying prospectus, including the information incorporated by reference into this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we have authorized for use in connection with this offering, in making your investment decision. You should also read and consider the information in the documents to which we have referred you in the sections entitled “Where You Can Find More Information” and “Incorporation of Certain Information by Reference” in this prospectus supplement.

We are offering to sell, and seeking offers to buy, our common shares only in jurisdictions where offers and sales are permitted. The distribution of this prospectus supplement and the accompanying prospectus and the offering of the common shares in certain jurisdictions may be restricted by law. Persons outside the United States who come into possession of this prospectus supplement and the accompanying prospectus must inform themselves about, and observe any restrictions relating to, the offering of the common shares and the distribution of this prospectus supplement and the accompanying prospectus outside the United States. This prospectus supplement and the accompanying prospectus do not constitute, and may not be used in connection with, an offer to sell, or a solicitation of an offer to buy, any securities offered by this prospectus supplement and the accompanying prospectus by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation.

All references in this prospectus supplement and the accompanying prospectus to “Fennec,” the “Company,” “we,” “us,” “our,” or similar references refer to Fennec Pharmaceuticals Inc. and its subsidiaries, except where the context otherwise requires or as otherwise indicated.

The Offering

Issuer	Fennec Pharmaceuticals Inc.

Manner of Offering	“At the market offering” that may be made from time to time through our sales agent, H.C. Wainwright & Co., LLC. See “Plan of Distribution.” Under the terms of the at the market offering agreement, we also may sell shares to the sales agent, as principal for its own account, at a price per share to be agreed upon at the time of sale. If we sell shares to the sales agent, acting as principal, we will enter into a separate terms agreement with that sales agent, setting forth the terms of such transaction, and we will describe the terms agreement in a separate prospectus supplement. No shares will be offered or sold in Canada, including through the TSX or any other trading market in Canada. The proceeds from this offering, if any, will vary depending on the number of shares that we offer and the offering price per share. There is no minimum amount required to be raised by this offering, and we may choose to raise less than the maximum $25,000,000 in gross offering proceeds permitted by this prospectus supplement.
Use of Proceeds	We presently intend to use the net proceeds from any sales of common shares resulting from this offering for the continuation of commercialization efforts of PEDMARK^® in the United States, preparation for commercialization of PEDMARK^® outside of the United States, and general corporate purposes. See “Use of Proceeds.”
Risk Factors	Before deciding to invest in our common shares, you should read carefully the risks set forth under the heading “Risk Factors” beginning on page S-3 of this prospectus supplement, and the risk factors set forth under the heading “Item 1A. Risk Factors” of our 2022 Annual Report, as well as any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, in addition to the other information contained in this prospectus supplement and the accompanying prospectus and the information incorporated by reference herein and therein for certain considerations relevant to an investment in our common shares.

RISK FACTORS

Investing in our common shares involves risks. In deciding whether to invest in our common shares, you should carefully consider the following risk factors and the risk factors included in our 2022 Annual Report, as well as any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, in addition to the other information contained in this prospectus supplement and the accompanying prospectus and the information incorporated by reference herein and therein. The risks and uncertainties described below and in our other filings with the SEC are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently deem immaterial, also may become important factors that affect us. If any of these risks occur, our business, financial condition or results of operations could be materially and adversely affected. In that case, the value of our common shares and your investment could decline. See “Forward-Looking Statements.”

Risks Related to This Offering

Future sales or issuances of our common shares may dilute the ownership interest of existing shareholders and depress the trading price of our common shares.

We cannot predict the effect, if any, that future sales of our common shares, including sales pursuant to the at the market offering agreement, or the availability of our common shares for future sale, will have on the market price of our common shares. Future sales or issuances of our common shares may dilute the ownership interests of our existing shareholders, including purchasers of common shares in this offering. In addition, future sales or issuances of substantial amounts of our common shares may be at prices below the offering price of the shares offered by this prospectus supplement and may adversely impact the market price of our common shares and the terms upon which we may obtain additional equity financing in the future. The perception that such sales or issuances may occur could also negatively impact the market price of our common shares.

The common shares offered hereby will be sold in “at the market” offerings, and investors who buy shares at different times will likely pay different prices.

Investors who purchase our common shares in this offering at different times will likely pay different prices. As a result, investors may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices and numbers of common shares sold, and there is no minimum or maximum sales price required in connection with this offering. Investors may experience a decline in the value of their common shares as a result of sales made at prices lower than the prices they paid.

The actual number of common shares we will issue pursuant to this offering, at any one time or in total, is uncertain.

Subject to certain limitations in the at the market offering agreement and compliance with applicable law, we have the discretion to deliver a sales notice to the sales agent at any time throughout the term of this offering. The number of common shares that are sold by the sales agent will fluctuate based on the market price of our common shares during the offering period and limits we set with the sales agent. Because the price per share of each common share sold will fluctuate based on the market price of our common shares during the offering period, it is not possible at this stage to predict the number of shares that will be ultimately issued or the amount of proceeds that we will receive from this offering.

You will likely experience immediate and substantial dilution in the net tangible book value per share of the common shares you purchase.

Since the price per common share pursuant to this offering is likely higher than the net tangible book value per common share, you will likely suffer substantial dilution in the net tangible book value of the common shares that you purchase in this offering. Based on an assumed offering price of $7.96 per common share, which was the last reported sale price of our common shares on the Nasdaq Capital Market on November 6, 2023, if you purchase common shares in this offering, you will suffer immediate and substantial dilution of approximately $7.51 per common share in the net tangible book value. See the section titled “Dilution” in this prospectus supplement for a more detailed discussion of the dilution you will likely incur if you purchase common shares in this offering. In addition, to the extent that outstanding stock options or warrants may be exercised or other common shares issued, you may experience further dilution. Furthermore, to the extent we need to raise additional capital in the future and we issue additional common shares or securities convertible or exchangeable for our common shares, our then-existing shareholders may experience dilution and the new securities may have rights senior to those of our common shares offered in this offering.

Management has broad discretion over the use of the proceeds from this offering. We may use the proceeds of this offering in ways that do not improve our operating results or the market value of our common shares.

We will have broad discretion in determining the specific uses of the net proceeds from the sale of the common shares pursuant to this offering. Our allocations may change in response to a variety of unanticipated events. We will also have significant flexibility as to the timing and use of the net proceeds. As a result, investors will not have the opportunity to evaluate the economic, financial or other information on which we base our decisions on how to use the net proceeds. You will rely on the judgment of our management with only limited information about their specific intentions regarding the use of proceeds. We may spend most of the net proceeds of this offering in ways which you may not agree with. If we fail to apply these funds effectively, our business, results of operations and financial condition may be materially and adversely affected.

S-3

USE OF PROCEEDS

We intend to use the net proceeds from this offering for the continuation of commercialization efforts of PEDMARK^® in the United States, preparation for commercialization of PEDMARK^® outside of the United States, and general corporate purposes. Our management will retain broad discretion over the allocation of the net proceeds from the sale of the common shares.

Therefore, investors in our common shares will be relying on the judgment of our management, who will have broad discretion regarding the application of the proceeds of this offering. The amounts and timing of our actual expenditures will depend upon numerous factors, including our ability to commercialize PEDMARK^® both inside and outside of the United States. We may find it necessary or advisable to use portions of the proceeds from this offering for other purposes.

Pending the application of the net proceeds, we intend to invest the net proceeds in money market accounts and/or investment-grade, interest-bearing securities. Our management has broad discretion over how these proceeds are used and could spend the proceeds in ways with which you may not agree, and the proceeds may not be invested in a manner that yields a favorable or any return.

S-4

DILUTION

If you invest in our common shares, you will likely experience immediate and substantial dilution to the extent of the difference between the public offering price of our common shares in this offering and the as adjusted net tangible book value per share of our common shares immediately after the offering.

Our net tangible book value per common share is determined by subtracting our total liabilities from our total tangible assets, which is total assets less intangible assets, and dividing this amount by the number of common shares outstanding. The historical net tangible book value of our common shares as of September 30, 2023 was approximately $(10.6) million, or $(0.40) per share, based on 26,632,950 common shares outstanding at September 30, 2023.

After giving effect to our sale in this offering of common shares in the aggregate amount of $25,000,000 at an assumed public offering price of $7.96 per share (the last reported sale price of our common shares on the Nasdaq Capital Market on November 6, 2023), and after deducting the sales agent commissions and our estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2023 would have been approximately $13.6 million, or $0.45 per share. This represents an immediate increase in net tangible book value of $0.85 per share to our existing shareholders and an immediate dilution of $7.51 per share to new investors purchasing common shares in this offering at the assumed public offering price. The following table illustrates this dilution on a per common share basis:

Assumed public offering price per common share				$	7.96
Net tangible book value per common share as of September 30, 2023	$	(0.40	)
Increase in net tangible book value per common share attributable to this offering based on assumed offering price	$	0.85
As adjusted net tangible book value per common share after this offering based on assumed offering price				$	0.45
Dilution per common share to new investors based on assumed offering price				$	7.51

The table above assumes for illustrative purposes that an aggregate of 3,140,704 common shares are sold at a price of $7.96 per share, the last reported sale price of our common shares on the Nasdaq Capital Market on November 6, 2023, for aggregate gross proceeds of approximately $25,000,000. The common shares sold in this offering, if any, will be sold from time to time at various prices. An increase of $1.00 per share in the price at which the shares are sold from the assumed public offering price of $7.96 per share shown in the table above, assuming all of our common shares in the aggregate amount of $25,000,000 are sold at that price, would increase the dilution in net tangible book value per share to new investors in this offering to $8.47 per share, after deducting commissions and estimated offering expenses payable by us. A decrease of $1.00 per common share in the price at which the shares are sold from the assumed public offering price of $7.96 per share shown in the table above, assuming all of our common shares in the aggregate amount of $25,000,000 are sold at that price, would decrease the dilution in net tangible book value per share to new investors in this offering to $6.49 per share, after deducting commissions and estimated offering expenses payable by us. This information is supplied for illustrative purposes only.

The table and discussion above are based on 26,632,950 common shares issued and outstanding on September 30, 2023 and excludes as of that date the following:

	·	5,005,452 common shares issuable upon the exercise of outstanding options having a weighted average exercise price of $5.94 per share ;
	·	150,000 common shares issuable upon the exercise of outstanding warrants having an exercise price of $7.79 per share;
	·	259,826 common shares underlying outstanding restricted stock units; and
	·	1,397,960 additional common shares reserved for issuance under our stock option plan.

To the extent that any of the outstanding warrants or options are exercised, there will be further dilution to new investors. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity securities, the issuance of these securities could result in further dilution to our shareholders.

S-5

PLAN OF DISTRIBUTION

We have entered into an at the market offering agreement with H.C. Wainwright & Co., LLC, the sales agent, under which we may issue and sell over a period of time, and from time to time, our common shares through the sales agent. This prospectus supplement relates to our ability to issue and sell over a period of time, and from time to time, up to $25,000,000 of our common shares through the sales agent. Prior to the effective date of the registration statement of which this prospectus supplement forms a part, offers and sales of our common shares pursuant to the at the market offering agreement were made under the prior registration statement. Upon the effective date of the registration statement of which this prospectus supplement forms a part, the offer and sale of our common shares pursuant to the at the market offering agreement will no longer be made under the prior prospectus, but will instead be offered and sold under this prospectus.

Sales of the shares to which this prospectus supplement and the accompanying prospectus relate, if any, will be made by means of ordinary brokers’ transactions on the Nasdaq Capital Market, or otherwise at market prices prevailing at the time of sale or negotiated transactions, or as otherwise agreed with the sales agent. In the event that any sales are made pursuant to the at the market offering agreement which are not made directly on the Nasdaq Capital Market or on any other existing U.S. trading market for our common shares at market prices at the time of sale, we will file a prospectus supplement describing the terms of such transaction, the amount of shares sold, the price thereof, the applicable compensation, and such other information as may be required pursuant to Rule 424 and Rule 430B under the Securities Act, as applicable, within the time required by Rule 424 under the Securities Act.

Upon written instructions from us, the sales agent will offer our common shares, subject to the terms and conditions of the at the market offering agreement, on a daily basis or as otherwise agreed upon by us and the sales agent. We will designate the maximum amount of common shares to be sold through the sales agent on a daily basis. Subject to the terms and conditions of the at the market offering agreement, the sales agent will use its commercially reasonable efforts to sell on our behalf all of the common shares so designated or determined. We may instruct the sales agent not to sell common shares if the sales cannot be effected at or above the price designated by us in any such instruction. We or the sales agent may suspend the offering of our common shares being made through the sales agent under the at the market offering agreement upon proper notice to the other party.

For its service as sales agent in connection with the sale of our common shares pursuant to this offering, we will pay the sales agent an aggregate fee of 3.0% of the gross sales price per common shares sold through it acting as our sales agent. The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any clearing firm, execution broker, governmental, regulatory or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such shares. We have agreed to reimburse the sales agent for certain of its expenses in an amount not to exceed $50,000, which amount was previously paid to the sales agent, in addition to the reimbursement of up to $2,500 per due diligence update session for the fees of counsel to the sales agent.

The sales agent will provide written confirmation to us following the close of trading on the Nasdaq Capital Market on each day in which common shares are sold by it on our behalf under the at the market offering agreement. Each confirmation will include the number of shares sold on that day, the gross sales price per share, the compensation payable by us to the sales agent and the proceeds to us net of such compensation and expenses for which we are responsible.

Settlement for sales of common shares will occur, unless the parties agree otherwise, on the second business day (or such earlier day as is industry practice for settlement) following the date on which any sales were made in return for payment of the proceeds to us net of compensation and expenses paid by us to the sales agent. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

Unless otherwise required, we will report at least quarterly the number of common shares sold through the sales agent under the at the market offering agreement, the net proceeds to us and the compensation paid by us to the sales agent in connection with the sales of common shares.

In connection with the sale of common shares on our behalf, the sales agent may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to the sales agent may be deemed to be underwriting commissions or discounts. We have agreed, under the at the market offering agreement, to provide indemnification and contribution to the sales agent against certain civil liabilities, including liabilities under the Securities Act.

To the extent required by Regulation M, as our sales agent, the sales agent will not engage in any transactions that stabilize our common shares while the offering is ongoing under this prospectus supplement.

S-6

The common shares offered pursuant to the at the market offering agreement have not been registered or qualified for distribution in any Province or Territory of Canada. The sales agent will not sell, offer to sell or solicit offers to purchase common shares in Canada, including through the Toronto Stock Exchange or any other trading markets in Canada, or to or from persons resident in any Province or Territory of Canada or to or from any person acquiring such common shares for the benefit of another person resident in any Province or Territory of Canada.

In the ordinary course of their business, the sales agent and/or its affiliates may perform investment banking, broker-dealer, financial advisory or other services for us for which they may receive separate fees.

We estimate that the total expenses from this offering payable by us, excluding compensation payable to the sales agent under the at the market offering agreement, will be approximately $75,000.

The offering of common shares pursuant to the at the market offering agreement will terminate upon the earlier of (i) the sale of all of our common shares provided for in this prospectus supplement or (ii) termination of the at the market offering agreement pursuant to its terms by either the sales agent or us.

LEGAL MATTERS

The validity of the common shares being offered by this prospectus supplement will be passed on for us by LaBarge Weinstein LLP, Ottawa, Ontario. The sales agent is being represented in connection with this offering by Ellenoff Grossman & Schole LLP, New York, New York.

Business Corporations Act (British Columbia)

Division 5 of Part 5 of the Business Corporations Act (British Columbia) provides that a corporation may (a) indemnify an eligible party against all eligible penalties to which the eligible party is or may be liable and (b) after the final disposition of an eligible proceeding, pay the expenses (not including judgments, penalties, fines or amounts paid in settlement of a proceeding) actually and reasonably incurred by an eligible party in respect of that proceeding.

An “eligible party” means an individual who (a) is or was a director or officer of the corporation, (b) is or was a director or officer of another corporation (i) at a time when the other corporation is or was an affiliate of the corporation, or (ii) at the request of the corporation, or (c) at the request of the corporation, is or was, or holds or held a position equivalent to that of, a director or officer of a partnership, trust, joint venture or other unincorporated entity.

An “eligible proceeding” means a proceeding in which an eligible party or any of the heirs and personal or other legal representatives of the eligible party, by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, the corporation or an associated corporation (a) is or may be joined as a party, or (b) is or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, the proceeding.

A corporation must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by the eligible party in respect of that proceeding if the eligible party (a) has not been reimbursed for those expenses, and (b) is wholly successful, on the merits or otherwise, in the outcome of the proceeding or is substantially successful on the merits in the outcome of the proceeding.

A corporation may pay, as they are incurred in advance of the final disposition of an eligible proceeding, the expenses actually and reasonably incurred by an eligible party in respect of that proceeding, provided the corporation first receives from the eligible party a written undertaking that, if it is ultimately determined that the payment of expenses is prohibited, the eligible party will repay the amounts advanced.

II-1

Notwithstanding any of the foregoing, a corporation must not indemnify an eligible party or pay the expenses of an eligible party if any of the following circumstances apply:

if the indemnity or payment is made under an earlier agreement to indemnify or pay expenses and, at the time that the agreement to indemnify or pay expenses was made, the corporation was prohibited from giving the indemnity or paying the expenses by its memorandum or articles;

if the indemnity or payment is made otherwise than under an earlier agreement to indemnify or pay expenses and, at the time that the indemnity or payment is made, the corporation is prohibited from giving the indemnity or paying the expenses by its memorandum or articles;

if, in relation to the subject matter of the eligible proceeding, the eligible party did not act honestly and in good faith with a view to the best interests of the corporation or the associated corporation, as the case may be;

in the case of an eligible proceeding other than a civil proceeding, if the eligible party did not have reasonable grounds for believing that the eligible party’s conduct in respect of which the proceeding was brought was lawful.

If an eligible proceeding is brought against an eligible party by or on behalf of the corporation or by or on behalf of an associated corporation, the corporation must not (a) indemnify the eligible party in respect of the proceeding or (b) pay the expenses of the eligible party in respect of the proceeding.

A corporation may purchase and maintain insurance for the benefit of an eligible party or the heirs and personal or other legal representatives of the eligible party against any liability that may be incurred by reason of the eligible party being or having been a director or officer of, or holding or having held a position equivalent to that of a director or officer of, the corporation or an associated corporation.

Articles

Our Articles provide that, subject to the Business Corporations Act (British Columbia), the Company must indemnify an eligible party and their respective heirs and personal or other legal representatives against all eligible penalties to which such eligible party is or may be liable. The Company must, after the final disposition of an eligible proceeding, pay the expenses actually and reasonably incurred by such person in respect of that proceeding. Each eligible party is deemed to have contracted with the Company on this term. The Articles also provide that the Company may indemnify any person, subject to any restrictions in the Business Corporations Act (British Columbia).

Our Articles defines the following terms: (1) an “eligible penalty” means a judgment, penalty or fine awarded or imposed in, or an amount paid in settlement of, an “eligible proceeding”; (2) an “eligible party” means a director, former director or alternate director of the Company; (3) an “eligible proceeding” means a legal proceeding or investigative action (whether current, threatened, pending or completed), in which an eligible party or any of the heirs and personal or other legal representatives of the eligible party, by reason of the eligible party being or having been a director or alternate director of the Company (a) is or may be joined as a party, or (b) is or may be liable for or in respect of a judgment, penalty or fine in, or expenses related to, the proceeding; and (4) “expenses” has the meaning set out in the Business Corporations Act (British Columbia).

Our Articles provide that the Company may purchase and maintain insurance for the benefit of any person (or his or her heirs or legal personal representatives) who is or was a director, alternative director, officer, employee or agent, or held or holds such position or a position equivalent to the foregoing (each, an “insured party”) with respect to (i) the Company; (ii) a corporation at a time when the corporation was an affiliate of the Company; (iii) at the request of the Company, served in such capacity with respect to a corporation, partnership, trust, joint venture or other unincorporated entity, against any liability that may be incurred by him or her acting in such capacity.

II-2

We maintain liability insurance policies regarding our directors and officers against certain liabilities that they may incur in such capacities.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 16. Exhibits.

Reference is made to the information contained in the Exhibit Index that precedes the signature page of this Registration Statement, which information is incorporated herein by reference pursuant to Rule 411 under the Securities Act.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1)	To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement;

(i)

to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii)

to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; and

(iii)

to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that the undertakings set forth in paragraphs (i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this Registration Statement.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)	To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

II-3

(4)	That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A)

each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the Registration Statement as of the date the filed prospectus was deemed part of and included in the Registration Statement; and

(B)

each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the Registration Statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the Registration Statement relating to the securities in the Registration Statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the Registration Statement or made in a document incorporated or deemed incorporated by reference into the Registration Statement or prospectus that is part of the Registration Statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the Registration Statement or prospectus that was part of the Registration Statement or made in any such document immediately prior to such effective date.

(5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this Registration Statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of an undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re:

Fennec Pharmaceuticals Inc. - Registration Statement on Form S-3

We have acted as counsel to Fennec Pharmaceuticals Inc., a corporation incorporated pursuant to the laws of British Columbia (the “Company”), in connection with a Registration Statement on Form S-3 filed on or about November 9, 2023 with the Securities and Exchange Commission (the “Registration Statement”) for the purpose of registering the sale from time to time up to an aggregate of $90,000,000 of common shares of the Company (the “Shares”).

In rendering this opinion, we have examined: (i) the Articles of the Company, as amended; (ii) certain resolutions of the Board of Directors of the Company (the “Board”) evidencing the corporate proceedings taken by the Company to authorize the issuance of the Shares, and (iii) such other documents as we have deemed appropriate or necessary as a basis for the opinion hereinafter expressed.

In rendering the opinion expressed below, we assumed the legal capacity of natural persons signing or delivering any instrument, the authenticity of all documents and records examined, the conformity with the original documents of all documents submitted to us as copies, and the genuineness of all signatures.

Based upon and subject to the foregoing, and such legal considerations as we deem relevant, we are of the opinion that the Shares will be validly issued, fully paid and non-assessable, assuming that (i) the Board or an authorized committee thereof will have specifically authorized the issuance of such Shares in exchange for consideration that the Board or such committee determines as adequate (the “Issuance Authorizing Resolutions”), and (ii) the Company has received the consideration provided for in the applicable Issuance Authorizing Resolutions.

The foregoing opinion is based solely on the present laws and applicable regulations of the Province of British Columbia and the laws of Canada in force therein. We express no opinion as to matters involving the laws of any other jurisdiction.

We hereby consent to the filing of this opinion as an Exhibit to the Registration Statement and to references made to this firm in the Registration Statement and all amendments thereto.

The opinions set forth in this letter are based upon the facts in existence and laws in effect on the date hereof and we expressly disclaim any obligation to update our opinions herein, regardless of whether changes in such facts or laws come to our attention after the delivery hereof.
