AUSTIN, Texas, Feb. 26, 2025 (GLOBE NEWSWIRE) -- Plus Therapeutics, Inc. (Nasdaq: PSTV) (the “Company” or “Plus Therapeutics”), a clinical-stage pharmaceutical company developing targeted radiotherapeutics with advanced platform technologies for central nervous system (CNS) cancers, today announced the completion of the ReSPECT-LM Phase 1 single-dose escalation trial, having determined an RP2D.

The ReSPECT-LM single-dose escalation trial assessed the safety, tolerability, and potential efficacy of intrathecally administered Rhenium (186Re) Obisbemeda in patients with leptomeningeal metastases (LM). Enrollment in Cohort 6 was recently completed (75.0 mCi). The Cohort 4 dose (44.1 mCi) was determined to be the RP2D; no dose-limiting toxicities were observed at this dose level. One patient at the Cohort 4 dose was observed to have achieved a complete response, as evidenced by the eradication of tumor cells in the cerebrospinal fluid—a key therapeutic endpoint.
