For the year ended December 31, Cellectar reported cash and cash equivalents of $13.2 million, a decline from $23.3 million in 2024. Research and Development expenses decreased to approximately $11.5 million, attributed to reduced activity in clinical studies and a completed production pipeline. The Net Loss for 2025 was reported at $21.8 million, a decrease compared to $44.6 million in 2024.
The company aims to strengthen its intellectual property portfolio, securing patents across various regions, further underpinning its innovative drug delivery strategies. Cellectar will host a conference call to discuss these developments, reinforcing its commitment to transparency and growth in the oncology sector.
MWN-AI** Analysis
Cellectar Biosciences (NASDAQ: CLRB) has recently reported an impressive turnaround in its financial performance for the year ended December 31, 2025, marked by significant corporate progress and a reduced net loss compared to 2024. The company's focus on its lead drug candidate, iopofosine I-131, a Phospholipid Drug Conjugate (PDC) aimed at treating Waldenström Macroglobulinemia, is gaining momentum. With an upcoming submission for Conditional Marketing Authorization (CMA) to the European Medicines Agency (EMA) anticipated in Q3 2026, the path to EU commercialization in 2027 appears promising.
Cellectar's cash reserves stood at $13.2 million at year's end, down from $23.3 million in 2024. While this decrease raises concerns about near-term liquidity, management asserts this position can sustain operations through Q3 2026. This projection is crucial as the company prepares for pivotal clinical milestones, particularly the Phase 1b dose-finding study of CLR 125 in Triple Negative Breast Cancer (TNBC), with preliminary data expected mid-2026.
The substantial reduction in research and development (R&D) expenses—from $26.1 million in 2024 to approximately $11.5 million—indicates a shift towards leaner operations, likely in response to the advanced stages of clinical trials. The receipt of Breakthrough Therapy Designation (BTD) from the U.S. FDA for iopofosine I-131 offers a compelling reason for investors to consider the stock, as it opens up additional treatment avenues.
Investors should cautiously monitor Cellectar's upcoming clinical trials and regulatory progress. The company's advancements in its radiotherapeutic platform, coupled with an expanding intellectual property estate, positions it favorably within the biopharmaceutical landscape. However, prospective investors should assess their risk tolerance given the inherent uncertainties of clinical outcomes and regulatory approvals. The planned conference call will provide further insights into management's strategic roadmap and financial health, which will be crucial for informed investment decisions.

2025 and Recent Corporate Highlights
- Iopofosine I 131, the Company’s Phospholipid Drug Conjugate (PDC) designed to provide targeted delivery of iodine-131 (radioisotope)
- Following advice from the European Medicines Agency’s (EMA) Scientific Advice Working Party (SAWP), the Company plans to submit a CMA for iopofosine I 131 as a treatment for in Waldenström Macroglobulinemia (WM). The CMA submission will be supported by data from the CLOVER WaM study, including 12-month follow-up on all patients, updated overall and major response rates, progression-free survival, duration of response, and compelling subset analyses on post-BTKi patients.
- Received Breakthrough Therapy Designation (BTD) from the U.S. Food and Drug Administration (FDA) for iopofosine I 131 in relapsed/refractory WM.
- Received recommendation from the FDA to investigate iopofosine I 131 as a treatment option in post-BTKi indications as early as the second line, substantially expanding the available patients in the U.S. market.
- CLR 121125 (CLR 125), an iodine-125 Auger-emitting program targeted for solid tumors
- Initiated a Phase 1b study of CLR 125 in Triple Negative Breast Cancer (TNBC).
- CLR 125 has been well tolerated in vivo with no signs of end-organ toxicity, including hematologic toxicity, and has also demonstrated reduction or inhibition of solid tumors in preclinical studies.
- Enrollment is ongoing in the Phase 1b dose finding study of CLR 125, which will evaluate three doses of 32.75 mCi/m2/dose for up to 4 cycles, 62.5 mCi/m2/dose for up to 3 cycles and 95 mCi/m2/dose for up to 2 cycles in patients with relapsed TNBC.
- The study’s primary endpoint is to determine a recommended Phase 2 dose and to evaluate safety, tolerability and initial response assessment (RECIST v1.1 and PFS).
- Secured a supply agreement with Ionetix to provide commercial-scale supply of cGMP-grade Actinium-225 (Ac-225) and Astatine-211 (At-211) to support ongoing CLR 225 clinical development programs.
- Corporate
- Strengthened and expanded the Company’s global intellectual property estate with newly issued patents across Europe, Asia-Pacific, the Middle East and the Americas. The expanded IP coverage protects both iopofosine I 131 as well as the broader radiotherapeutic pipeline, including CLR 125.

2025 Financial Highlights
- Cash and Cash Equivalents: As of December 31, 2025, the company had cash and cash equivalents of $13.2 million, compared to $23.3 million as of December 31, 2024. The company believes its cash balance as of December 31, 2025, is adequate to fund its basic budgeted operations into the third quarter of 2026.
- Research and Development Expenses: R&D expenses for the year ended December 31, 2025, were approximately $11.5 million, compared to approximately $26.1 million for the year ended December 31, 2024. The decrease was primarily a result of reduced activity in our CLOVER WaM clinical study, as we were exclusively in patient follow-up during 2025. Additionally, manufacturing costs declined as we completed development of a fully redundant production and logistics pipeline.
- General and Administrative Expenses: G&A expenses for the year ended December 31, 2025, were approximately $11.5 million, compared to approximately $25.6 million for the same period in 2024. The decrease was primarily a result of reduced pre-commercialization efforts and related personnel.
- Other income and expense: Other income and expense, net, was approximately $1.2 million of income in 2025, as compared to approximately $7.3 million of income in the prior year. These amounts are almost exclusively a result of non-cash impacts from the cost to issue and in the valuation of certain warrants that are considered liabilities.
- Net Loss: Net loss for the full year ending December 31, 2025, was $21.8 million or $8.35 per basic and diluted share, compared with $44.6 million or $36.52 per basic share and $41.89 per diluted share during 2024.

About Cellectar Biosciences, Inc.
Cellectar Biosciences is a late-stage clinical biopharmaceutical company focused on the discovery and development of proprietary drugs for the treatment of cancer, independently and through research and development collaborations. The company’s core objective is to leverage its proprietary Phospholipid Drug Conjugate™ (PDC) delivery platform to develop the next-generation of cancer cell-targeting treatments, delivering improved efficacy and better safety as a result of fewer off-target effects.
The company’s product pipeline includes iopofosine I 131, which is a PDC designed to provide targeted delivery of iodine-131 (radioisotope). Iopofosine I 131 has been tested in Phase 2b trials as a treatment for relapsed or refractory Waldenström Macroglobulinemia (WM), in relapsed or refractory multiple myeloma (MM) and central nervous system (CNS) lymphoma. The CLOVER-2 Phase 1b study is evaluating iopofosine I 131 in pediatric patients with high-grade gliomas, for which Cellectar is eligible to receive a Pediatric Review Voucher from the FDA upon approval. The FDA has granted iopofosine I 131 Breakthrough, six Orphan Drug, four Rare Pediatric Drug and two Fast Track Designations for various cancer indications, and the EMA has granted iopofosine I 131 PRIority MEdicines (PRIME) designation.
Cellectar is also developing CLR 121125 (CLR 125), an iodine-125 Auger-emitting program targeted for solid tumors, such as triple negative breast (TNBC), lung, and colorectal cancer, and is currently being evaluated in a Phase 1b study for TNBC, which will determine the recommended dose for the subsequent Phase 2 trial. CLR 125 has been well tolerated in vivo and has demonstrated strong preclinical data showing reduction or inhibition of solid tumor growth.
In addition to these assets, the Cellectar team is developing CLR 121225 (CLR 225), an actinium-225 based program targeting solid tumors in indications with significant unmet need, such as pancreatic cancer, as well as proprietary preclinical PDC chemotherapeutic programs and multiple partnered PDC assets.
