MADISON, Wis., June 23, 2016 (GLOBE NEWSWIRE) -- Cellectar Biosciences, Inc. (CLRB) (“the company”), an oncology-focused biotechnology company, today announces the results of the first phase of a National Cancer Institute (NCI)-funded Small Business Innovation Research (SBIR) Phase 1 contract for a study of CLR 125, a radiotherapeutic isotope, which may be uniquely suited to treat micro-metastatic disease, conjugated to the company’s proprietary phospholipid drug conjugate (PDC) delivery platform.
The study demonstrated that a single dose of CLR 125 reduced the volume of human-derived primary triple negative breast cancer xenografts (tumor models) by approximately 60 percent, compared to a control vehicle (p<0.001), as well as significantly extending survival. CLR 125 also significantly weakened the progression of micrometastases (p< 0.01) and reduced established metastases (p< 0.01) compared to the control vehicle. Importantly, within 96 hours of dosing, investigators observed that radioactivity cleared from subjects’ blood and organs and accumulated primarily in the tumor cells where it was retained past 144 hours.
“These study results provide further validation of the benefits of our Phospholipid Drug Conjugate (PDC) development program, whether in cytotoxics, as in our previously announced paclitaxel program or radiotherapeutics, as this study demonstrated,” said Jim Caruso, president and CEO of Cellectar Biosciences. “Further, these data clearly show that our PDC delivery platform may possess clinical utility in a broad range of cancer types with a wide variety of cytotoxic compounds.”
This trial represents the first phase of the SBIR contract for a Phase 1 study sponsored by NCI. Following a complete review of the data, an assessment of potential clinical applications, and differentiated product benefits, both NCI and the company will determine whether to advance CLR 125 into phase 2 of the contract.
About Cellectar Biosciences, Inc.
Cellectar Biosciences is developing phospholipid drug conjugates (PDCs) designed to provide cancer targeted delivery of diverse oncologic payloads to a broad range of cancers and cancer stem cells. Cellectar’s PDC Delivery Platform is based on the company’s proprietary phospholipid ether analogs. These novel small-molecules have demonstrated highly selective uptake and retention in a broad range of cancers. Cellectar’s PDC pipeline includes product candidates for cancer therapy and cancer diagnostic imaging. The company’s lead therapeutic PDC, CLR 131, utilizes iodine-131, a cytotoxic radioisotope, as its payload. CLR 131 is currently being evaluated under an orphan drug designated Phase 1 study in patients with relapsed or refractory multiple myeloma. The company is actively developing PDCs for targeted delivery of chemotherapeutics such as paclitaxel (CLR 1602-PTX), a preclinical stage product candidate, and plans to expand its PDC chemotherapeutic pipeline through both in-house and collaborative R&D efforts.
