Analysis · RADX · Life Sciences
An End-of-Phase 2 meeting with the FDA has been scheduled for October 1, 2026, to align on the pivotal Phase 3 trial design for RAD101, the company's imaging agent for brain metastases. The Phase 2b trial met its primary endpoint with 93% concordance between MRI and PET imaging. This critical regulatory milestone de-risks the program and sets a clear path to Phase 3 readiness by year-end. A manufacturing partnership with Siemens Healthineers was also announced to support the upcoming trial. Given the company's tight cash position (A$4.1 million as of Q2 2026) and recent dilutive financings, this positive clinical and regulatory progress is a significant counterweight, potentially improving financing terms and investor sentiment.
