Explanatory Note: This Amendment No. 16 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 C. 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 (“SEC”) on October 14, 2008 and amended on November 10, 2008, November 24, 2008, December 29, 2008, February 18, 2009, October 26, 2009, June 3, 2010, May 3, 2011, July 7, 2011, May 11, 2012, July 30, 2012, May 9, 2013, November 22, 2013, June 27, 2014, June 12, 2015 and April 14, 2016 (as amended, the “Statement”), with respect to the Common Stock, $0.01 par value (the “Common Stock”), of Heron Therapeutics, Inc., a Delaware corporation (the “Issuer” or “Company”).
 
Items 3, 4, 5 and 6 of the Statement are hereby amended to the extent hereinafter expressly set forth. 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:
 
Tang Capital Partners, LP received $70,087 principal amount of senior secured convertible notes due 2021 (the “Notes”) on July 1, 2016 as interest paid-in-kind on the existing Notes held by Tang Capital Partners, LP.
 
On June 16, 2016, Tang Capital Partners, LP exercised a warrant to purchase 1,250,000 shares of the Issuer's Common Stock. The warrant was exercised by way of cashless exercise, which resulted in the withholding of 243,639 of the warrant shares to pay the exercise price and the issuance of 1,006,361 shares of the Issuer's Common Stock to Tang Capital Partners, LP.

Tang Capital Partners, LP holds some of its shares in 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 these accounts.  The margin accounts may from time to time have debit balances.  Since other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the securities reported herein. 
 
Item 4.
Purpose of Transactions
 
Item 4 of the Statement is hereby amended to add the following:
            
On August 5, 2016 (the “Closing Date”), the Issuer entered into a subordinated secured promissory note (the “Promissory Note”) and a security agreement (the “Security Agreement”) with Tang Capital Partners, LP whereby Tang Capital Partners, LP agreed to lend the Issuer up to $100 million. The Promissory Note has a two-year term and bears interest of 8% per annum. The first close of $50 million occurred on the Closing Date. The second close of an additional $50 million is subject to the achievement of a corporate milestone. There are no fees, no warrants and no equity conversion feature associated with this transaction. The Promissory Note is secured by a second-priority lien on substantially all of the Issuer’s assets.
