Ladies and Gentlemen:

This letter constitutes supplemental correspondence on behalf of Cellectar Biosciences, Inc., a Delaware corporation (the “Company”), related to and filed together with the Company’s Registration Statement on Form S-3 (the “Registration Statement”).

The Company was required to file this Registration Statement within 60 days after October 1, 2015 pursuant to a registration rights agreement with the Selling Stockholders, even though the Warrants will not become exercisable until April 1, 2016.
