MADISON, Wis., Sept. 24, 2018 (GLOBE NEWSWIRE) -- Cellectar Biosciences, Inc. (Nasdaq: CLRB), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer, announces today that the U.S. Food and Drug Administration (FDA) has initiated direct talks with the company concerning a possible exemption for CLR 131 from the Import Alert placed on the Centre for Probe Development and Commercialization (CPDC), the sole supplier of Cellectar’s drug CLR 131.
As announced on August 10, 2018, Cellectar was informed by CPDC of the Import Alert on August 7, 2018, and further learned that the basis for the Import Alert was not related to CLR 131 or to CPDC’s production facility associated with CLR 131. Since notification of the Import Alert, Cellectar has been actively assisting CPDC to secure the timely removal of the Import Alert. Recently, the FDA initiated direct talks with Cellectar on a potential pathway to remove CLR 131 from the Import Alert and allow CPDC to resume supply of CLR 131.
“We are encouraged that the FDA initiated a direct dialogue with us regarding a potential resolution for the Import Alert that is affecting CLR 131,” said James Caruso, president and CEO of Cellectar Biosciences. “This issue remains a top priority for Cellectar and although we are not currently able to assess whether the FDA will exempt CLR 131 from the Import Alert, we are working closely with the agency and plan to respond quickly to any information requests.”
About CLR 131
CLR 131 is Cellectar’s investigational radioiodinated PDC therapy that exploits the tumor-targeting properties of the company's proprietary phospholipid ether (PLE) and PLE analogs to selectively deliver radiation to malignant tumor cells, thus minimizing radiation exposure to normal tissues. CLR 131 is in a Phase 2 clinical study in R/R MM and a range of B-cell malignancies and a Phase 1b clinical study in patients with R/R MM exploring fractionated dosing. The objective of the multicenter, open-label, Phase 1b dose-escalation study is the characterization of safety and tolerability of CLR 131 in patients with R/R MM. Patients in Cohorts 1-4 received single doses of CLR 131 ranging from 12.5 mCi/m2 to 31.25 mCi/m2 as well as a fractionated dose of 15.625 mCi/m2 given twice over seven days in Cohort 5. All study doses and regimens have been deemed safe and well tolerated by an independent Data Monitoring Committee. The company is currently initiating a Phase 1 study with CLR 131 in pediatric solid tumors and lymphoma and is planning a second Phase 1 study in combination with external beam radiation for head and neck cancer.
