ABOUT THE COMPANY
Company Overview
We are a late-stage development biopharmaceutical company, with an ongoing registration directed trial, committed to advancing new medicines for patients battling cancer. Our pipeline is focused on novel anticancer agents that inhibit critical signaling pathways in cancer that promote cancer cell survival and tumor growth, particularly rapidly accelerated fibrosarcoma (“RAF”)/mitogen-activated protein kinase kinase (“MEK”) inhibition and focal adhesion kinase (“FAK”) inhibition. Our most advanced product candidates, avutometinib (VS-6766) and defactinib, are being investigated in both preclinical and clinical studies for the treatment of various solid tumors, including, but not limited to low-grade serous ovarian cancer (“LGSOC”), non-small cell lung cancer (“NSCLC”), colorectal cancer, pancreatic cancer, and melanoma. We believe that avutometinib may be beneficial as a therapeutic, as a single agent or when used together in combination with defactinib, other agents, other pathway inhibitors, or other current and emerging standard of care treatments in cancers that do not adequately respond to currently available therapies.
Avutometinib is an orally available first-in-class unique small molecule RAF/MEK clamp. Defactinib is an oral small molecule inhibitor of FAK and proline-rich tyrosine kinase that is currently being evaluated as a potential combination therapy for various solid tumors. FAK is a non-receptor tyrosine kinase encoded by the protein tyrosine kinase-2 (“PTK-2”) gene that is involved in cellular adhesion and, in cancer, metastatic capability. The combination of avutometinib and defactinib has been found to be clinically active in some patients with Kirsten rat sarcoma viral oncogene homolog (“KRAS”) mutant and KRAS wild-type LGSOC and has received breakthrough designation from the U.S. Food & Drug Administration (the “FDA”) for the treatment of all patients with recurrent LGSOC, regardless of KRAS status, after one or more prior lines of therapy including platinum-based chemotherapy.
In the fourth quarter of 2020, we commenced two registration-directed trials investigating avutometinib as a monotherapy and in combination with defactinib. The registration-directed trials are entitled RAMP 201 and RAMP 202. RAMP 201 is an adaptive two-part multicenter, parallel cohort, randomized, open label trial to evaluate the efficacy and safety of avutometinib alone and in combination with defactinib in patients with recurrent LGSOC. RAMP 202 is a Phase 2, adaptive two-part multicenter, parallel cohort, randomized, open-label trial to evaluate the efficacy and safety of avutometinib alone and in combination with defactinib in patients with KRAS G12V NSCLC, following treatment with a platinum-based regimen and immune checkpoint inhibitor. Additionally, and based on preclinical rationale, we added additional cohorts to the RAMP 202 study including KRAS non-G12V NSCLC and B-Raf proto-oncogene serine/​threonine kinase mutant (V600E and non-V600E) NSCLC.
In January 2023, we reported data from a planned interim analysis of Part A of the ongoing RAMP 201 trial among patients with LGSOC treated with avutometinib alone and in combination with defactinib. The combination of avutometinib and defactinib has been declared the go-forward treatment regimen based on a higher rate of confirmed objective responses in a planned interim analysis with prespecified criteria. We will continue future enrollment of RAMP 201 in the combination arm only in all patients with recurrent LGSOC regardless of their KRAS status. Target enrollment for the combination arm has been achieved.
In the fourth quarter of 2022, a type B meeting with the FDA was held to discuss the results to date of the ongoing RAMP 201 trial, confirm the go-forward treatment regimen selection and discuss the regulatory path forward. We are in ongoing discussions with the FDA on the confirmatory study and plan to provide an update after agreement with the FDA. Continued enrollment in the combination arm of RAMP 201 is planned to expand the clinical experience in anticipation of initiation of a confirmatory study.
In October 2022, we reported data from a planned interim analysis of Part A from the RAMP 202 trial among patients with KRAS G12V NSCLC treated with avutometinib or the combination of avutometinib and defactinib. The results did not meet the pre-defined criteria to continue to the trial expansion phase. Among patients with KRAS non-G12V NSCLC, no KRAS subtype was identified for further clinical evaluation of avutometinib with defactinib in this trial.
Avutometinib and defactinib are currently being investigated in combination with immunotherapeutic and other agents through investigator sponsored trials.

DESCRIPTION OF PRIVATE PLACEMENT
On January 24, 2023, the Company entered into a private placement (the “Private Placement”) of up to 2,144,160 shares of its Series B Preferred Stock, through a securities purchase agreement (the “Purchase Agreement”). The Series B Preferred Stock will be convertible into the Company’s common stock, par value $0.0001 per share, at the option of the holders at any time, subject to certain limitations, at a conversion rate equal to $0.5901 per share.
The Company agreed to sell and issue in the first tranche of the Private Placement 1,200,000 shares of Series B Preferred Stock at a purchase price of $25.00 per share of Series B Preferred Stock (equivalent to $0.5901 per share of common stock). The first tranche of the Private Placement closed on January 27, 2023. The Company received gross proceeds from the first tranche of the Private Placement of approximately $30.0 million, before deducting fees to the placement agent and other offering expenses payable by the Company.
In addition, the Company agreed to sell and issue in the second tranche of the Private Placement 944,160 shares of Series B Preferred Stock at a purchase price of $31.77 per share of Series B Preferred Stock (equivalent to $0.75 per share of common stock) if at any time within 18 months following the closing of the first tranche the 10-day volume weighted average price of the Company’s common stock (as quoted on Nasdaq and as calculated by Bloomberg) should reach at least $1.125 per share (adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as needed) with aggregate trading volume during the same 10-day period of at least $25 million within 18 months from the closing date of the initial tranche. The second tranche of the Private Placement is expected to close within seven trading days of meeting the second tranche conditions and will be subject to additional, customary closing conditions. If the second tranche conditions are satisfied, the Company anticipates receiving gross proceeds from the second tranche of the Private Placement of approximately $30.0 million, before deducting fees to the placement agent and other offering expenses payable by the Company.
DESCRIPTION OF CAPITAL STOCK
The description of our common stock and our preferred stock, including the Series B Preferred Stock, is incorporated by reference to Exhibit 4.5 of our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 14, 2023.

Other risks and uncertainties include those identified under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022, and in any subsequent filings with the SEC.
