Explanatory Note: This Amendment No. 17 relates to and
amends the Statement of Beneficial Ownership on Schedule 13D/A (“Schedule 13D/A”) of Tang Capital Partners, LP, a Delaware
limited partnership, Tang Capital Management, LLC, a Delaware limited liability company, and Kevin Tang, a United States citizen (each,
a “Reporting Person” and collectively, the “Reporting Persons”), initially filed jointly by the Reporting Persons
with the U.S. Securities and Exchange Commission on August 7, 2014, and amended on September 2, 2014, September 30, 2014, December 16,
2014, May 15, 2015, June 24, 2015, August 21, 2015, March 7, 2016, March 6, 2017, March 1, 2018, March 20, 2018, January 14, 2019, January
14, 2020, June 26, 2020, August 18, 2020, September 11, 2020 and May 27, 2021 (as amended, the “Statement”), with respect
to the Common Stock, $0.0001 par value (the “Common Stock”), of La Jolla Pharmaceutical Company, a California corporation
(the “Issuer”).
Items 3 and 5 of the Statement are hereby
amended to the extent hereinafter expressly set forth. Except as amended hereby, the original disclosure set forth in the Statement
shall remain unchanged. All capitalized terms used and not expressly defined herein have the respective meanings ascribed to such
terms in the Statement.
Item 3. Source and Amount of Funds
or Other Consideration
Item 3 of the Statement is hereby amended to
add the following:
Between May 27, 2021 and June 1, 2021, the Reporting Persons
expended an aggregate of approximately $1.1 million to purchase 245,020 shares of the Issuer’s Common Stock, which has not previously
been required to be reported on a Schedule 13D/A. Such purchases were effected through the open market. The Common Stock was acquired
in the ordinary course of business. Subject to the following paragraph, Tang Capital Partners, LP used its own funds for the purchases,
none of which were borrowed or otherwise obtained from any other source.
Tang Capital Partners, LP maintains commingled margin accounts
with various financial institutions, which may extend margin credit to Tang Capital Partners, LP as and when required, to open or carry
positions in the margin accounts, subject to applicable federal margin regulations, stock exchange rules and credit policies. In such
instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the accounts.
The margin accounts may from time to time have debit balances. Since multiple different securities are held in the margin accounts, it
is not possible to determine the amounts, if any, of margin used to purchase the shares of Common Stock reported herein.
Item 5. Interest in Securities of the Issuer.
The information previously provided in response
to Item 5 of the Statement is hereby amended and restated by replacing the text thereof in its entirety with the following:

beneficial owner of any of the Issuer’s Common Stock underlying such Series C-12 Preferred for purposes of Section 13(d)
