Explanatory Note

 

This Amendment No. 6 to Schedule 13D (this “Amendment No. 6”) amends and supplements the Statement on Schedule 13D filed with the United States Securities and Exchange Commission on February 5, 2014, as amended to date (the “Statement”) by (i) RA Capital Management, LLC (the “RA Capital”), (ii) Peter Kolchinsky and (iii) RA Capital Healthcare Fund, L.P. (“Fund” and together with each of the foregoing, the “Reporting Persons”), relating to the Common Stock (the “Common Stock”) of Dicerna Pharmaceuticals, Inc. (the “Issuer”). Capitalized terms used herein without definition shall have the meaning set forth in the Statement.

 

Item 5.  Interest in Securities of the Issuer

 

Item 5(a)-(b) of the Statement is hereby amended and restated in its entirety as follows:

 

(a)-(b) See Items 7-11 of the cover pages and Item 2 of this Statement.

 

Item 5(c) of the Statement is hereby amended and supplemented by adding the following:

 

(c) From the date of the most recent amendment to this Schedule 13D through November 1, 2018, the Reporting Persons disposed of 608,500 shares of Common Stock in a series of open market transactions on the Nasdaq Global Market. Details by date of the transactions are as follows:

 

Transaction Date No. Shares Price
Sell 30-Oct-2018 219,072* and 30,928    $13.8603
Sell 31-Oct-2018 156,330* and 22,070    $13.4619
Sell 1-Nov-2018 157,820* and 22,280   $13.3757

 

Shares marked with an * were acquired by the Fund. The remaining shares were acquired for the Account.

  

(d) None.

 

(e) As a result of the transactions described herein, the Fund no longer beneficially owns more than 5% of the outstanding Common Stock and therefore, upon the filing of this amendment, will no longer be a Reporting Person.
