CUSIP No.   1312EM 10 4

 

This Amendment No. 3 (“Amendment No. 3”) to Schedule 13D amends and supplements the Schedule 13D originally filed with the United States Securities and Exchange Commission on December 20, 2010 as amended on December 21, 2010 and on March 28, 2012 (collectively, the “Schedule 13D”) relating to the beneficial ownership by R. Merrill Hunter (the “Reporting Person”) of common stock, par value $0.0001 per share (the “Common Stock”), of Callisto Pharmaceuticals, Inc., a Delaware corporation (the “Issuer”).  Information reported in the Schedule 13D, as amended, remains in effect except to the extent that it is expressly amended, restated or superseded by information contained in this Amendment No. 3. Capitalized terms used in this Amendment No. 3 without definition have the meanings ascribed to them in the Schedule 13D.

 

 

Item 5.

Interest in Securities of the Issuer.

 

Item 5 is hereby amended and restated in its entirety as follows:

 

The responses of the Reporting Person to rows (7) through (13) of the cover page of this Schedule 13D are referenced herein.

 

Pursuant to the Agreement and Plan of Merger, dated as of July 20, 2012, as amended October 15, 2012, by and between Synergy Pharmaceuticals Inc (“Synergy”) and the Issuer (the “Merger Agreement”), the Issuer merged with and into Synergy (the “Merger”). Upon the effective time of the Merger, each share of Issuer common stock was cancelled and exchanged for .1799 shares of Synergy common stock (the “Exchange Ratio”).

 

As a result of the Merger, all of the shares of Issuer common stock held by the Reporting Person have been cancelled, and at the effective time of the Merger, January 17, 2013, the Reporting Person owns no shares of Issuer Common Stock and ceases to be the beneficial owner of more than 5% of the outstanding shares of common stock of the Issuer.

 

 

Item 6.

The description of the Merger Agreement described in Item 5 is hereby incorporated by reference.
