Company Seeking Conditional Approval from European Medicines Agency (EMA) for Iopofosine I 131 in Waldenstrom Macroglobulinemia based upon CLOVER WaM Phase 2 Study Data
CLOVER WaM Major Response Rate for BTKi-Treated Patients 59.0%
Company to hold webcast and conference call at 8:30 AM ET today
FLORHAM PARK, N.J., May 13, 2025 (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 March 31, 2025, and provided a corporate update on its promising portfolio of clinical and pre-clinical radiopharmaceutical therapeutics.
“Notwithstanding the need to gather additional clinical data for iopofosine I 131, as previously announced, we believe that the Phase 2 CLOVER WaM clinical trial data for this product candidate are impressive. We plan to present these data to the EMA during the second quarter of 2025 as part of the registration package seeking conditional marketing approval. We anticipate a response regarding the regulatory pathway from the European agency before the end of the third quarter of this year,” said James Caruso, president and CEO of Cellectar. “In addition to iopofosine I 131, we have developed a pipeline of radiotherapeutic candidates, including our alpha- and Auger-emitting radioconjugates, with observed preclinical activity in solid tumor models. With cash into the fourth quarter of this year we are evaluating a variety of funding pathways to successfully advance our novel pipeline assets.”
Corporate Update
- Announced plans to explore full range of strategic alternatives including, but not limited to mergers, acquisitions, partnerships, joint ventures, licensing arrangements or other strategic transactions. The company’s board of directors has engaged of Oppenheimer & Co. Inc. to serve as exclusive financial advisor to assist in the strategic evaluation process.
- Determined that the Phase 3 study for iopofosine I 131, for the treatment of relapsed/refractory Waldenstrom macroglobulinemia, would be a comparator, randomized controlled study with 100 patients per arm. Study initiation is dependent upon the company obtaining additional funding or a strategic collaboration.
- Funding dependent, the company is prepared to initiate a Phase 1b/2a dose-finding study for CLR 121125, the company’s lead Auger-emitting (iodine-125) PRC, in triple-negative breast cancer. CLR 121125 is designed to provide highly precise radiotherapeutic targeting as emissions only travel a few nanometers.
- In a series of pre-clinical studies evaluating CLR 121225, the company’s lead alpha-emitting actinium-225 PRC in refractory pancreatic models, desired pharmacokinetics, biodistribution and activity were observed, further supporting future clinical development.
First Quarter 2025 Financial Highlights
- Cash and Cash Equivalents: As of March 31, 2025, the company had cash and cash equivalents of $13.9 million, compared to $23.3 million as of December 31, 2024. The company believes its cash balance as of March 31, 2025, is adequate to fund its basic budgeted operations into the fourth quarter of 2025.
- Research and Development Expenses: R&D expenses for the three months ended March 31, 2025, were approximately $3.4 million, compared to approximately $7.1 million for the three months ended March 31, 2024. The overall decrease was primarily a result of the reduction in patient follow-up activities for our CLOVER WaM Phase 2 clinical study in WM and a reduction in personnel costs.
- General and Administrative Expenses: G&A expenses for the three months ended March 31, 2025, were approximately $3.0 million, compared to approximately $4.9 million for the same period in 2024. The decrease was primarily driven by a reduction in pre-commercialization and personnel costs.
- Net Loss: The net loss attributable to common stockholders for the three months ended March 31, 2025, was $6.6 million, or $0.14 per share, compared to $26.6 million, or $0.91 per share in the three months ended March 31, 2024.
