Cellectar Biosciences Partners with MiBA, a Data Subsidiary of American Oncology Network, to Advance the Treatment of Waldenstrom's Macroglobulinemia in the Community Setting

Partnership to Provide Key Data on WM Treatment Landscape and Community Clinic Access to Support Iopofosine I 131 Commercialization Strategy

FLORHAM PARK, N.J., Jan. 11, 2024 (GLOBE NEWSWIRE) -- Cellectar Biosciences, Inc. (NASDAQ: CLRB), a late-stage clinical biopharmaceutical company focused on the discovery, development and commercialization of targeted drugs for the treatment of cancer, announced today a partnership to advance the treatment of Waldenstrom's macroglobulinemia (WM) in the community setting with American Oncology Network (AON), a leading oncology platform with an innovative model of physician-led, community-based oncology management, and its data arm subsidiary Meaningful Insights-BioTech Analytics (MiBA), a healthcare AI technology company on a mission to close the feedback loop between physicians, patients, and industry partners.

"AON is currently managing over 650 Waldenstrom’s macroglobulinemia patients,” said Dr. Fred Divers, chief medical officer of AON. “We are committed to providing promising new radiotherapies, starting with Cellectar’s iopofosine I 131, a novel phospholipid radiotherapeutic conjugate, throughout our nationwide network of clinics. It is critical for patients to have access to advances in the treatment of this rare cancer, where there is currently no standard of care for those with relapsed or refractory disease. The pivotal topline data for iopofosine demonstrating an overall response rate of 76.5% and 100% disease control rate utilizing a four dose fixed course of therapy in a heavily pretreated relapse/refractory WM patient population is very compelling when compared to response rates of other therapeutic options in this setting.”

Positive topline data from the pivotal Clover WaM study for iopofosine I 131 was reported on January 8, achieving the primary endpoint with a 61% major response rate (MRR) and exceeding the protocol statistical hurdle of 20%. This was the largest study to date in relapsed or refractory WM patients post-BTKi therapy and represents the most refractory population ever tested in clinical studies based upon a review of published literature. Iopofosine I 131 was well tolerated and its toxicity profile was consistent with the Company's previously reported safety data.

“We are extremely pleased to be partnering with AON and MiBA to support our collective goal to enrich the WM treatment paradigm for patients and providers,” said James Caruso, president and CEO of Cellectar. “This collaboration will provide additional insight to patients’ and health care providers’ needs across the WM treatment landscape and the learnings will be incorporated into the launch strategy for iopofosine I 131. Following achievement of the primary endpoint in the CLOVER WaM pivotal study, this partnership with AON represents another strategically important collaboration to ensure patient access and optimize outcomes with iopofosine therapy upon FDA approval.”

AON is one of the fastest growing networks of community oncology practices with 85 sites of care across the U.S. focused on delivering high-quality cancer care. The partnership with AON and MiBA is a key addition to Cellectar’s planned collaborations with leading U.S. community-based cancer care networks to identify unmet WM patient needs and opportunities to optimize the potential commercial launch for iopofosine I 131.

“We are very excited to be able to support the efforts of all involved in this project with MiBA’s technical and analytical capabilities,” said Mark Moch, Executive Manager at MiBA. “Data identification, curation and advanced analytics are essential in moving treatments forward. Keeping our patient at the center and working in close association with AON and Cellectar, gives us the ability to positively affect outcomes and contribute to future standards of care.”

The U.S. Food and Drug Administration (FDA) has granted Cellectar’s iopofosine I 131, a small-molecule Phospholipid Drug Conjugate™ (PDC) designed to provide targeted delivery of iodine-131 (radioisotope), Orphan and Fast Track Designation for relapsed/refractory WM patients.

WM is a rare type of B-cell lymphoma that originates from the bone marrow lymphocytes. It is estimated that 26,000 people are living with WM in the U.S. and greater than 10,000 are in a second-line plus stage of treatment. Currently there are limited treatment options with only one approved class of drugs and no established standard of care beyond second-line therapy.
