7. Upcoming Events & Catalysts

8. Investment Considerations

Strengths

• Late-stage asset with strong clinical data and multiple expedited regulatory designations.

• Upcoming EMA decision could unlock significant value and market access.

• Strategic review may result in value-creating transactions or partnerships.

Risks

• No commercial revenue; continued losses and cash burn.

• Regulatory and clinical trial outcomes are binary and high risk.

• Dilution risk if additional capital is raised.

• Strategic review may not result in a transaction.

9. Conclusion

CLRB is a speculative, catalyst-driven investment with substantial upside potential if regulatory and strategic milestones are achieved. The company’s financial position is precarious, but the late-stage pipeline and ongoing strategic review provide significant optionality. Investors should weigh the high risk of loss against the potential for outsized returns, and closely monitor upcoming regulatory decisions and corporate developments.

Pre-Revenue Model Analysis for Cellectar Biosciences (CLRB)

Key Model Assumptions

• Cash (Q1 2025): $13.9 million

• Annual Net Loss (Burn Rate, FY 2024): $44.6 million

• Probability of Success: 25% (reflects late-stage, orphan drug, but high risk)

• Time to Approval: 2 years (EMA/FDA decisions pending)

• Peak Sales Estimate: $250 million (orphan indication, conservative)

• Discount Rate: 25% (high risk, pre-revenue biotech)

• Royalty/Net Margin Equivalent: 20%

• Exclusivity Window: 7 years post-approval

Model Results

Discounted Future Cash Flows (Millions)

• Interpretation: The model projects a negative risk-adjusted NPV, primarily due to the high burn rate, short cash runway, and the significant risk of failure typical for pre-revenue biotech companies. Even with a successful launch, the company would need to secure additional funding or partnerships to bridge the gap to commercialization.

Detailed Review of Pharma Agreements and Collaborations

1. Supply and Manufacturing Partnerships

• Nusano (2025): Multi-year supply agreement for iodine-125 and actinium-225, critical for Cellectar’s radiotherapeutic pipeline and upcoming clinical trials (CLR-125 for triple-negative breast cancer, CLR-225 for pancreatic cancer). This ensures uninterrupted access to key isotopes for both clinical and future commercial needs.

• SpectronRx (2024): Manufacturing partnership to support global supply and commercialization of iopofosine I 131, expanding Cellectar’s manufacturing capabilities and logistics for global market distribution.

• NorthStar Medical Radioisotopes (2024): Partnership for supply of actinium-225, supporting advancement of CLR 121225 into human clinical trials.

2. Clinical and Commercial Collaborations

• AON/MiBA (2023): Collaboration with American Oncology Network (AON) and MiBA, an AI healthcare technology company, to optimize the commercial launch of iopofosine I 131 and identify unmet needs in Waldenstrom Macroglobulinemia (WM) across 85 U.S. cancer care sites.

• Orano Med (2018): Joint development of novel phospholipid drug conjugates (PDC™) using Orano Med’s alpha emitter (lead-212) and Cellectar’s phospholipid ether (PLE) technology. Early preclinical costs are shared, with options for joint commercialization after proof-of-concept.

3. Licensing and Intellectual Property Agreements

• Wisconsin Alumni Research Foundation (WARF, 2017 & 2023):

  • 2017: Exclusive license for CLR 131 in multiple myeloma, consolidating Cellectar’s control over this indication.

  • 2023: Expanded exclusive license for iopofosine I 131 in pediatric solid cancers (high-grade glioma, neuroblastoma, sarcoma), strengthening the patent portfolio and enabling further clinical development.

Summary Table: Key Agreements

Conclusion

• Financial Outlook: Cellectar’s short cash runway and negative risk-adjusted NPV highlight the urgent need for additional funding or a strategic transaction. The company’s future hinges on successful regulatory outcomes and the ability to monetize its pipeline through partnerships or licensing.

• Collaborative Strength: Cellectar has established a robust network of supply, manufacturing, clinical, and licensing agreements with leading pharma, isotope suppliers, and academic institutions. These partnerships are critical for advancing its pipeline, securing clinical and commercial supply, and expanding its intellectual property portfolio.

• Investor Consideration: The company’s extensive collaborations and supply agreements de-risk certain operational aspects but do not offset the high financial and regulatory risks inherent in pre-revenue biotech investing. Close monitoring of upcoming regulatory decisions and partnership developments is essential.
