Management to Host Conference Call and Webcast at 5:00 PM EDT

MADISON, Wis., Aug. 20, 2014 (GLOBE NEWSWIRE) -- Cellectar Biosciences, Inc. (Nasdaq:CLRB), a clinical stage biopharmaceutical company developing innovative agents for the detection and treatment of cancer, is providing an overview of its development programs and financial results for the second quarter 2014.

"During the second quarter 2014, we completed the management transition initiated in late 2013, made meaningful progress in our development programs and garnered well-earned recognition for the innovative nature of our platform technology," commented Dr. Simon Pedder, Cellectar's president and chief executive officer. "In addition to having clinical results from our PET imaging and therapeutic programs selected for poster and platform presentation at this year's ASCO annual meeting, we were honored to have a publication detailing the selective uptake and prolonged retention of our molecules chosen as the cover article for the prestigious journal Science Translational Medicine. This publication reflects nearly a decade of research related to our platform technology and highlights the potential of our agents to enable truly personalized dual modality cancer therapy that combines tumor imaging and therapy using the same highly-selective, cancer-targeting core delivery platform."

Recent Highlights:

• Publication by lead author Dr. Jamey Weichert, Cellectar's chief scientific officer and founder, detailing cancer-selective uptake and retention of Cellectar's delivery platform, PET imaging and therapeutic agents selected as cover story for June 11, 2014 issue of Science Translational Medicine
• Presented data from Phase Ib trial of I-131-CLR1404 at the American Society of Clinical Oncology (ASCO) 2014 Annual Meeting
• Filed Investigational New Drug (IND) application to evaluate I-131-CLR1404 in clinical trials in relapsed/refractory multiple myeloma, an incurable cancer of plasma cells
• Secured orphan drug designation for I-124-CLR1404 as a diagnostic for the management of glioma, the most common and aggressive form of brain cancer
• Appointed Chad J. Kolean Chief Financial Officer
• Dr. Simon Pedder became full-time president and chief executive officer
• Completed underwritten offering generating new gross proceeds of $13.5 million
• Eliminated $4.0 million debt issued in February 2014 private placement
• Obtained approval for common stock to begin trading on Nasdaq Capital Market

"With the data from our on-going Phase II imaging trial of 1-124-CLR1404 in glioblastoma expected in the first half of 2015 and data from our proof of concept trials of 1-131-CLR1404 for the treatment of multiple myeloma and CLR1502 for real time optical imaging in breast cancer surgery expected by year-end 2015, the coming year is poised to be a big one for Cellectar," continued Dr. Pedder. "Having now completed an underwritten offering generating new gross proceeds of $13.5 million and simultaneously receiving approval for our stock to begin trading on the Nasdaq Capital Market, we are now well-positioned to meaningfully advance these three key clinical programs and drive both near and long term shareholder value."

Research and development (R&D) expenses for the quarter ended June 30, 2014 were $1.4 million, compared to $1.6 million for the second quarter of 2013. For the six months ended June 30, 2014, Cellectar's research and development expenses were $3.1 million compared to $3.2 million during the first six months of 2013.

Cellectar's general and administrative (G&A) expenses were essentially unchanged year-over-year with second quarter 2014 G&A expenses totaling approximately $1.0 million compared to $1.1 million during the second quarter 2013.

Using a novel phospholipid ether analog (PLE) platform technology as a targeted delivery and retention vehicle, Cellectar's compounds are designed to be selectively taken up and retained in cancer cells including cancer stem cells. With the ability to attach both imaging and therapeutic agents to its proprietary delivery platform, Cellectar has developed a portfolio of product candidates engineered to leverage the unique characteristics of cancer cells to "find, treat and follow" malignancies in a highly selective way. I-124-CLR1404 is a small-molecule, broad-spectrum, cancer-targeted PET imaging agent currently being evaluated in a Phase II glioblastoma imaging trial. I-124-CLR1404 has been granted Orphan status as a diagnostic for the management of gliomas from the US FDA. Additionally, multiple investigator-sponsored Phase I/II clinical trials are ongoing across 11 solid tumor indications. I-131-CLR1404 is a small-molecule, broad-spectrum, cancer-targeted molecular radiotherapeutic that delivers cytotoxic radiation directly and selectively to cancer cells including cancer stem cells. A Phase Ib dose-escalation trial of I-131-CLR1404 in patients with advanced solid tumors was completed in the second quarter of 2014 and results presented at the American Society of Clinical Oncology (ASCO) 2014 Annual Meeting. CLR1502 is a preclinical, cancer-targeted, non-radioactive optical imaging agent for intraoperative tumor margin illumination and non-invasive tumor imaging.
