Dr. Simon Pedder to Retire

MADISON, Wis., June 16, 2015  — Cellectar Biosciences, Inc. (Nasdaq:CLRB), today announces that James V. Caruso was appointed as president and chief executive officer yesterday, replacing Dr. Simon Pedder who has retired due to personal family reasons.  Mr. Caruso was also named to Cellectar’s Board as a Director.

Mr. Caruso, 56, brings more than 25 years of industry experience to the role, having served most recently as executive vice president, chief operating officer and co-founder of HIP Innovation Technology, LLC.  He previously held positions as executive vice president, chief commercial officer at Allos Therapeutics, senior V.P., sales and marketing at Bone Care International, as well as a variety of sales and marketing leadership positions at Novartis, Bristol Myers-Squibb and BASF. At both Allos Therapeutics and Bone Care International, Mr. Caruso worked closely with current Cellectar director Paul Berns, contributing significantly to those companies’ successful growth, which led to acquisitions by Spectrum and Genzyme, respectively. Mr. Caruso brings a wide range of expertise in both drugs and devices, including a strong background in oncology. He holds a B.S. in finance from the University of Nevada.

“Jim’s appointment comes at a critical time in the evolution and growth of Cellectar,” said Dr. Stephen Hill, chairman of Cellectar’s board of directors.  “He brings a level of energy and commitment, combined with his significant industry experience that I am confident will enable Cellectar to achieve the potential we all believe is inherent in its technology.”

“Cellectar presents an important opportunity in the market and I look forward to collaborating with the team to achieve defined corporate objectives, including the optimization of our novel PLE platform technology and advancing our innovative therapeutic and diagnostic agents through the clinic,” said Mr. Caruso.

Dr. Simon Pedder has resigned as CEO and president, and as a director of Cellectar, and will retire from full-time employment. Cellectar’s Board of Directors and shareholders thank him for the leadership he provided since October 2013.

Cellectar also announces the appointment of Stefan Loren, Ph.D. as an independent Director. Dr. Loren, 51, is the founder of Loren Capital Strategy (LCS), a start-up firm investing in and advising public and private health care companies. Prior to LCS, Dr. Loren held the position of managing director at Westwicke Partners, developing and executing capital markets, business development and investor relations strategies. He is currently a director at GenVec and Marina Biosciences.

“The breadth and depth of Dr. Loren’s experience in the biotechnology space, along with his experience in strategic planning and investor relations, will add greatly to the board’s expertise and oversight,” said Dr. Hill.
