Summary of Radiopharm Theranostics (RADX) Update / Briefing Company and Industry Overview - **Company**: Radiopharm Theranostics (RADX) - **Industry**: Prostate cancer treatment and radiopharmaceuticals Key Points and Arguments 1. **Prostate Cancer Treatment Landscape**: - Significant advancements in prostate cancer treatments, particularly with radiotherapy options like radium-223 combined with enzalutamide and targeted therapies such as PSMA radiotherapeutics like Pluvicto [3][4] - Pluvicto has shown efficacy in prostate cancer patients both before and after chemotherapy, as evidenced by the PSMA-4 and VISION trials [3] 2. **Unmet Medical Needs**: - Despite advancements, there remains a substantial medical need for new therapies, especially targeted radiotherapy, as all patients receiving PSMA-targeting treatments will eventually relapse [4] 3. **Introduction of Betabart**: - Betabart, a monoclonal antibody targeting B7-H3, is being developed as a new treatment option. It has a modified half-life to reduce side effects while maintaining strong target affinity [4][5] - The upcoming study will enroll patients with various tumors, including those with prostate cancer who have previously received Pluvicto [5] 4. **KLK3 Targeting**: - KLK3 (PSA) is identified as a promising new target for prostate cancer therapy, with a focus on its specific expression in prostate tissues compared to PSMA, which is expressed in multiple organs [7][8] - The KLK3-targeted study is set to begin in Australia early next year [8] 5. **Preclinical Data**: - Preclinical studies show that KLK2 and KLK3 are highly specific to prostate tissues, with KLK3 exhibiting higher expression levels than KLK2 [9][19] - The therapeutic efficacy of KLK2-targeted therapies has been demonstrated in advanced mouse models, showing significant tumor reduction [13][14] 6. **Mechanism of Action**: - The therapeutic approach exploits the upregulation of androgen receptors (AR) in response to DNA damage, which increases the expression of KLK2 and KLK3, enhancing the targeting efficacy over time [16][29] 7. **Comparison with Other Therapies**: - KLK3-targeted therapies are positioned as a more advanced approach compared to KLK2, with a higher expression level and a more extensive research background [20][29] - The antibody developed for KLK3 is designed to avoid targeting PSA in circulation, focusing instead on the free form of PSA in tissues [28] 8. **Clinical Development Plans**: - RAD402 (KLK3 targeting molecule) is expected to enter clinical studies in Australia before the end of the year, alongside RV-01 (B7-H3 targeting molecule) in the U.S. [48] Additional Important Content - **Market Potential**: - The arrival of radiopharmaceuticals has significantly changed the metastatic prostate cancer treatment landscape, with improved patient survival rates [45] - There is a recognition that existing treatments like Pluvicto are not perfect, indicating a need for further scientific advancements [46] - **Future Directions**: - The company is exploring new targets and approaches to enhance treatment efficacy and patient outcomes in metastatic prostate cancer [46][47] - **Community Engagement**: - The webinars have attracted significant interest, indicating a strong community engagement and support for ongoing research and development in prostate cancer therapies [45]

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.
