FLORHAM PARK, N.J., Aug. 13, 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 financial results for the quarter ended June 30, 2024, and provided a corporate update. "With our recent positive data announcement from the CLOVER WaM pivotal study evaluating iopofosine I 131 in Waldenstrom's macroglobulinemia, we remain focused on filing our WM NDA in the fourth quarter of this year," said James Caruso, president and CEO of Cellectar. "We anticipate an accelerated six-month NDA review period and continue to prepare for a potential launch of iopofosine in 2025. We look forward to bringing this meaningful therapy to market and establishing iopofosine I 131 as the standard of care for the treatment of relapsed and refractory WM patients." Second Quarter and Recent Corporate Highlights Announced final data exceeded the primary endpoint in the company's CLOVER WaM pivotal study evaluating iopofosine I 131, a potential first-in-class, targeted radiotherapeutic candidate for the treatment of relapsed/refractory Waldenstrom's macroglobulinemia (WM) patients that received at least two prior lines of therapy, including Bruton tyrosine kinase inhibitors (BTKi's). Data from the pivotal study demonstrated an 80% overall response rate (ORR), and a 56.4% major response rate (MRR) which exceeded the agreed-upon primary endpoint of a 20% MRR. The median number of prior lines of therapy was 4 (range, 2-14), with approximately 27% of patients' refractory to all available therapies (BTKi, anti-CD20 antibody, chemotherapy), and 40% of patients dual-class refractory (BTKi and rituximab). Notably, comparable iopofosine I 131 ORRs were observed across all clinically challenging disease subgroups, including: MYD99-wt (81%; n=16), P53-mutated (80%; n=5), and clinical patient cohorts including post-BTKi (72%; n=39), as well as dual-class (59%; n=22), and triple-class (53%; n=15) refractory patients. Secondary endpoints of disease control rate (98.2%) and duration of response (DoR) presented evidence that iopofosine provided durable clinical benefit across all response categories. The median DoR in patients achieving major response and overall response were not reached as of the data cutoff, ...
