Cellectar Biosciences Receives Additional U.S. Patents for PDC Optical Agents in the Detection of Multiple Cancers
Madison, Wisc. (April 25, 2017 ) -- Cellectar Biosciences, Inc. (Nasdaq: CLRB) (the “company”), an oncology-focused, clinical stage biotechnology company, today announces the United States Patent and Trademark Office has granted a method of use patent for CLR 1501, CLR 1502 and an additional CLR 1401-boron-dipyrromethene analog for the detection of multiple cancer types. All of these compounds utilize Cellectar’s proprietary phospholipid drug conjugate (PDC) delivery platform.
The recently issued patent, 9,616,140, outlines the method of
use of these fluorophore compounds to detect a variety of solid tumors in patients, including melanomas, colorectal adenocarcinoma,
uterine carcinoma, pancreatic carcinoma, ovarian adenocarcinoma, glioblastoma, clear cell carcinoma, and prostate adenocarcinoma.
The current patent provides intellectual property protection through May 11, 2029.
“We continue to successfully execute our plan to expand the company’s intellectual property portfolio to protect and enhance the value of our PDC pipeline assets, both in diagnostic and therapeutic applications,” said Jim Caruso, president and CEO of Cellectar. “While our focus continues to be the development of our therapeutic assets, specifically CLR 131, for the treatment of multiple myeloma and other hematologic malignancies, our platform assets offer significant additional opportunity in a variety of clinical applications.”
About Phospholipid Drug Conjugates (PDCs)
Cellectar’s product candidates are built upon its patented cancer cell-targeting delivery and retention platform of optimized phospholipid ether-drug conjugates (PDCs). The company deliberately designed its phospholipid ether (PLE) carrier platform to be coupled with a variety of payloads to facilitate both therapeutic and diagnostic applications. The basis for selective tumor targeting of our PDC compounds lies in the differences between the plasma membranes of cancer cells compared to those of normal cells. Cancer cell membranes are highly enriched in lipid rafts, which are glycolipoprotein microdomains of the plasma membrane of cells that contain high concentrations of cholesterol and sphingolipids, and serve to organize cell surface and intracellular signaling molecules. PDCs have been tested in more than 80 different xenograft models of cancer.
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 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 I clinical study in patients with relapsed or refractory multiple myeloma. In addition, the company has initiated a Phase II clinical study to assess efficacy in a range of B-cell malignancies. The company is also 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.
