Plus Therapeutics Introduces REYOBIQ™, FDA-Accepted Proprietary Name for Lead Drug Candidate

 REYOBIQ™ (rhenium Re¹⁸⁶ obisbemeda) continues to be under clinical investigation for Leptomeningeal Metastases (LM) and Recurrent Glioblastoma (GBM)

HOUSTON, March 20, 2025 (GLOBE NEWSWIRE) — Plus Therapeutics, Inc. (Nasdaq: PSTV) (the “Company”), a clinical-stage pharmaceutical company developing targeted radiotherapeutics with advanced platform technologies for central nervous system (CNS) cancers, today announces the U.S. Food and Drug Administration (FDA) has conditionally accepted the Company’s new proprietary name, REYOBIQ™, for its lead therapeutic candidate. A request for proprietary name review for REYOBIQ™ must be submitted once the marketing application (NDA) is submitted. All communications regarding the USAN-adopted and INN-recommended rhenium Re¹⁸⁶ obisbemeda generic name will now utilize the proprietary name REYOBIQ™.

“Branding is an important part of preparing for commercialization, and the establishment of the REYOBIQ™ brand will enable investigators, investors, and potential patients to connect with our rhenium-based radiotherapeutic beyond its chemical identity,” said Russ Havranek, Plus Therapeutics VP of Corporate Strategy and New Product Planning. “We are looking forward to building familiarity with the new REYOBIQ™ name and logo, as we believe it will foster stronger stakeholder engagement and reinforce the promising progress we are making in developing targeted radiotherapeutics for LM and GBM.”

About REYOBIQ™ (rhenium Re¹⁸⁶ obisbemeda)
REYOBIQ™ (rhenium Re¹⁸⁶ obisbemeda) is a novel injectable radiotherapy specifically formulated to deliver direct targeted high dose radiation in CNS tumors in a safe, effective, and convenient manner to optimize patient outcomes. REYOBIQ™ has the potential to reduce off target risks and improve outcomes for CNS cancer patients, versus currently approved therapies, with a more targeted and potent radiation dose. Rhenium-186 is an ideal radioisotope for CNS therapeutic applications due to its short half-life, beta energy for destroying cancerous tissue, and gamma energy for real-time imaging. REYOBIQ™ is being evaluated for the treatment of recurrent glioblastoma and leptomeningeal metastases in the ReSPECT-GBM and ReSPECT-LM clinical trials. ReSPECT-GBM is supported by an award from the National Cancer Institute (NCI), part of the U.S. National Institutes of Health (NIH), and ReSPECT-LM is funded by a three-year $17.6M grant by the Cancer Prevention & Research Institute of Texas (CPRIT).
