Cellectar Biosciences, Inc. — Investor Relations & Filings
Cellectar Biosciences, Inc. is a clinical-stage biopharmaceutical company focused on the discovery and development of targeted cancer treatments. The company's core technology is a proprietary Phospholipid Drug Conjugate (PDC) platform that selectively delivers therapeutic payloads, such as radioisotopes and cytotoxins, to cancer cells by targeting lipid rafts in their plasma membranes. This approach is designed to maximize antitumor activity while minimizing off-target effects on healthy tissue. Cellectar's lead product candidate is iopofosine I 131, a first-in-class PDC that delivers the radioisotope iodine-131. It is being developed for the treatment of hematologic malignancies and has received Breakthrough Therapy Designation from the U.S. Food and Drug Administration (FDA) for Waldenstrom's Macroglobulinemia.
