Ailawadhi, Sikander, M.D., Lead Investigator, to Present Iopofosine I 131 Efficacy and Safety Results from Phase 2 CLOVER-WaM Study
Highlights Company's Leadership and Progress in Developing Iopofosine I 131 as Treatment for Waldenstrom's Macroglobulinemia
FLORHAM PARK, N.J., Nov. 07, 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 that new data from the company's open-label Phase 2 CLOVER-WaM study of iopofosine I 131 as a potential treatment for Waldenstrom's macroglobulinemia (WM) will be highlighted in an oral presentation at the 66th American Society of Hematology Annual Meeting and Exposition (ASH 2024) taking place from December 7-10, 2024, in San Diego, California.
Cellectar's lead product candidate, iopofosine I 131, is a potential first-in-class, novel cancer targeting agent utilizing a phospholipid ether as a radioconjugate. Iopofosine I 131 is an investigational agent and has not been approved for use in any country, for any indication.
WM is the dominant subtype lymphoplasmacytic lymphoma that remains incurable with available therapies. Treatment options beyond initial therapy are limited, underscoring the need for new therapies with novel mechanisms of action.
The pivotal CLOVER-WaM (NCT02952508) trial assessed the efficacy and safety of iopofosine I 131 in relapsed and refractory patients with WM who received at least 2 prior therapies.
"We are honored to have the positive results from our CLOVER-WaM pivotal trial selected for oral presentation at ASH 2024. This highlights the need for novel class therapies for an often-overlooked patient population affected by this rare disease in which iopofosine I 131 has the potential to establish itself as the standard-of-care for relapsed/refractory patients,” said James Caruso, president and CEO of Cellectar. "As previously announced, we plan to submit a New Drug Application with the U.S. Food and Drug Administration in the coming months and, given the limited effective therapeutic alternatives available for WM patients, will be seeking priority review.”
Details for the presentations are as follows:

About Waldenstrom's Macroglobulinemia
Waldenstrom's Macroglobulinemia (WM) is a B-cell malignancy characterized by bone marrow infiltration with clonal lymphoplasmacytic cells that produce a monoclonal immunoglobulin M (IgM) that remains incurable with available treatments. The prevalence in the US is approximately 26,000 with 1,500-1,900 patients being diagnosed annually. Approximately 11,500 patients require treatment in the relapsed or refractory setting and there are an estimated 4,700 patients requiring third line or greater therapy. There are also approximately 1,000 patients that have exhausted all current treatment options by third line because they are ineligible or intolerant to those existing therapies. Therefore, the total addressable market for third line or greater therapy is approximately 5,700 patients. There are no U.S. Food and Drug Administration (FDA) approved treatment options for patients progressing on BTKi therapy. BTKi therapies do not demonstrate complete response rates and require continuous treatment.
Non-FDA approved treatments are used in more than 60% of patients. Over 50% of patients are treated with the same or similar treatment from prior lines of therapy. There is an established unmet need for new FDA-approved treatment like Iopofosine I-131 that provide a novel mechanism of action, increased deep durable responses, and time limited treatment, especially in heavily pretreated WM patients.
