Summary of Radiopharm Theranostics (RADX) Update / Briefing August 26, 2025 Company and Industry Overview - **Company**: Radiopharm Theranostics (RADX) - **Industry**: Oncology, specifically focusing on prostate cancer treatment and radiopharmaceutical therapies Key Points and Arguments 1. **Prostate Cancer Treatment Landscape**: The treatment of prostate cancer has evolved significantly, moving from traditional methods like surgery and chemotherapy to incorporating genetics, molecular imaging, and targeted therapies, including immunotherapy and radiopharmaceuticals [11][12][30] 2. **B7-H3 as a Target**: B7-H3 is highlighted as a promising new target for prostate cancer treatment, being highly expressed in various tumors, including 93% of castrate-resistant prostate cancer cases. This makes it a viable alternative to PSMA-targeted therapies, especially in cases where PSMA expression is low [39][41][43] 3. **Need for New Therapies**: There is a critical need for more effective therapies for metastatic castration-resistant prostate cancer, as current treatments often provide limited survival benefits [18][30] 4. **NCCN Guidelines**: The National Comprehensive Cancer Network (NCCN) guidelines are discussed, emphasizing the importance of treatment sequencing and the variety of options available based on prior therapies [19][20] 5. **Theranostics Concept**: The concept of theranostics is introduced, where ligands are designed to bind to specific cancer cell targets, allowing for both diagnosis and treatment using radiopharmaceuticals [24][25] 6. **Clinical Trials and FDA Approvals**: The presentation mentions several clinical trials demonstrating survival benefits from new therapies, including the FDA approval of Plavicto (lutetium-177) for prostate cancer treatment [27][28][51] 7. **BetaBART Development**: The development of BetaBART, a humanized monoclonal antibody targeting the four Ig isoform of B7-H3, is presented as a novel approach in radioimmunotherapy, with plans for a Phase 1 trial in 2025 [51][66] 8. **Competitive Landscape**: The competitive landscape for B7-H3 targeting is discussed, noting that while there are other modalities like ADCs and CAR T-cell therapies, the unique properties of BetaBART provide a competitive advantage [75][78][87] 9. **Immunological Memory**: Evidence of secondary immune memory from prior treatments suggests that BetaBART may not only target tumors but also enhance the immune response against them [64][66] 10. **Market Potential**: The potential market for B7-H3 targeting therapies is significant, with opportunities extending beyond prostate cancer to other solid tumors [46][51] Other Important but Overlooked Content 1. **Challenges with Current Therapies**: The limitations of existing therapies, including the need for better options post-Plavicto treatment, are emphasized, highlighting the urgency for innovation in this space [30][102] 2. **Mechanism of Action**: The mechanism of action for BetaBART is discussed, focusing on its ability to selectively target the four Ig isoform of B7-H3 while minimizing off-target effects and toxicity [49][66] 3. **Future Directions**: The discussion includes the need for randomized control groups in future trials to better assess the efficacy of new treatments [31] This summary encapsulates the critical insights from the briefing, focusing on the advancements in prostate cancer treatment, the significance of B7-H3 as a target, and the innovative approaches being developed by Radiopharm Theranostics.
