Explanatory Note: This Amendment No. 15 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 and June 12, 2015 (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 and 5 of the Statement are hereby amended to the extent herein after 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:

On December 22, 2015, the Issuer granted to Kevin C. Tang stock options to purchase an aggregate of 17,000 shares of Common Stock at an exercise price of $29.41 per share. The stock options vest monthly over a one-year period.

Tang Capital Partners, LP received $66,035, $67,026, $68,031 and $69,051 principal amount of senior secured convertible notes due 2021 (the “Notes”) on each of July 1, 2015, October 1, 2015, January 1, 2016 and April 1, 2016, respectively, as interest in-kind on the existing Notes held by Tang Capital Partners, LP.

Tang Capital Partners, LP holds some of its shares in commingled margin accounts, 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 5.

Tang Capital Partners, LP is the beneficial owner of 6,117,530 shares of Common Stock, including 937,500 shares of Common Stock held by Tang Holdings and 1,250,000 shares of Common Stock underlying the 2011 Warrant. Tang Capital Partners, LP shares voting and dispositive power over such shares and warrant with Tang Capital Management, LLC and Kevin C. Tang.

Tang Capital Partners, LP is the record owner of $4,672,481 principal amount of Notes, which may be converted into Common Stock at a conversion rate of 1,250 shares per $1,000 principal amount of Notes, subject to certain limitations discussed below.
 
Tang Capital Partners, LP has no right to convert the Notes to the extent that after giving effect to such conversion Tang Capital Partners, LP (together with its affiliates) would beneficially own in excess of the Maximum Percentage, which is currently set at 9.99%, of the number of shares of Common Stock of the Company outstanding immediately after giving effect to such conversion. Tang Capital Partners, LP can increase or decrease the Maximum Percentage for its Notes by written notice to the Company, provided that such increase or decrease will not be effective until 61 days after delivery of the notice. The foregoing limitation remains in effect with respect to such Notes, and, accordingly, no shares are currently issuable upon conversion of such Notes. Neither the filing of this Schedule 13D/A nor any of its contents shall be deemed to constitute an admission by Tang Capital Partners, LP or any other person that is the beneficial owner of any of the Common Stock underlying such Notes for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose, and, as such, beneficial ownership is expressly disclaimed and is not reflected herein.

Tang Capital Partners, LP is the record owner of a warrant to purchase up to 1,250,000 shares of Common Stock at an exercise price of $3.60 per share (the “2011 Warrant”).  The 2011 Warrant was issued on July 1, 2011, but was subject at the time of issuance to a limitation on the ability to exercise to the extent that, post-exercise, the holder would beneficially hold more than 9.99% of the Issuer’s outstanding Common Stock (the “Warrant Blocker”). The Warrant Blocker was waivable by the holder upon providing at least 61 days’ prior written notice.  On April 11, 2016, Tang Capital Partners, LP provided written notice of the waiver of the Warrant Blocker, which waiver will be effective as of June 13, 2016.  As a result, the 2011 Warrant will be exercisable anytime from June 13, 2016 until its expiration on July 1, 2016.
