Cellectar Biosciences and NorthStar Medical Radioisotopes Announce Partnership for Supply of Actinium-225

NorthStar to provide Cellectar with non-carrier-added Ac-225 for its expanded portfolio of clinical programs

FLORHAM PARK, N.J., Nov. 14, 2024 (GLOBE NEWSWIRE) -- Cellectar Biosciences, Inc. (NASDAQ: CLRB) a late-stage clinical biopharmaceutical company focused on the discovery, development and commercialization of drugs for the treatment of cancer, today announced the signing of a strategic supply agreement with NorthStar Medical Radioisotopes, LLC, for the procurement of NorthStar's non-carrier added (n.c.a.) Ac-225. The Company's CLR 121225 development program combines its proprietary Phospholipid Ether (PLE) delivery platform and actinium 225 for the treatment of solid tumors.

Existing supply chains for medical radioisotopes are often strained, posing a challenge to patient care, clinical trials, and ongoing drug development. Actinium-225 (Ac-225) is considered a rare radioisotope and is in short supply for clinical development and commercialization.

"Our PLE platform provides a unique ability to optimize delivery of any radioisotope and can be designed for the treatment of specific tumor types. Our leading alpha emitter program, CLR 121225, utilizes Ac-225 and has demonstrated promising preclinical results in pancreatic, triple negative breast and other solid tumors, justifying the progression to clinical development," said James Caruso, president and CEO of Cellectar. "We plan to advance CLR 121225 into human clinical trials in 2025 as part of a broader strategy to bring first-and best-in-class radiotherapeutics to market. This agreement with NorthStar provides a reliable source of Ac-225, which is a critical to our clinical development strategy."

NorthStar is a global innovator in the development, production, and commercialization of radiopharmaceuticals used for therapeutic applications and medical imaging including non-carrier added (n.c.a) Ac-225.

"Recent years have seen increased interest in alpha-emitting radiotherapies like Cellectar's novel TAT compounds, including CLR 121225 and others, but development activities have been hampered by the relative scarcity of Ac-225 supply," said Frank Scholz, president and CEO of NorthStar. "Our passion is to reduce technological and operational barriers to give companies like Cellectar a reliable source of environmentally preferred, high purity (n.c.a) Ac-225 that will help make these new therapies possible."

The agreement provides supply of Ac-225 from NorthStar for 10 years, and initiation is expected to occur in 2025.

CLR 121225 is an investigational therapy and not yet approved by any regulatory authority.
