AUSTIN, Texas, Dec. 03, 2024 (GLOBE NEWSWIRE) -- Plus Therapeutics, Inc. (Nasdaq: PSTV), a clinical-stage pharmaceutical company focused on developing innovative radiotherapeutics, today announced the renewal of its Master Services Agreement (MSA) with Telix IsoTherapeutics Group Inc. (‘IsoTherapeutics’, a Telix Group company). This MSA secures a reliable supply of cGMP Re-186, the radioisotope used in Plus Therapeutics’ lead radiotherapeutic candidate Rhenium (¹⁸⁶Re) Obisbemeda.

“This continuing agreement with Telix IsoTherapeutics Group builds on our recently announced partnership with SpectronRx and reflects our comprehensive supply chain strategy,” said Marc H. Hedrick, M.D., Plus Therapeutics’ President and Chief Executive Officer. “By securing supply of Re-186 through IsoTherapeutics and leveraging SpectronRx for final drug manufacturing of Rhenium (¹⁸⁶Re) Obisbemeda, we are establishing a scalable, end-to-end supply chain that positions us to meet the demands of late-stage clinical trials and future commercial needs.”

Key highlights of the agreement:

• Focus on the production of key radionuclide intermediate aluminum perrhenate and the final processing of cGMP Re-186
• Enables expanded, scalable, just-in-time manufacturing to support overall supply chain

About Rhenium (¹⁸⁶Re) Obisbemeda

Rhenium (¹⁸⁶Re) 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. Rhenium (¹⁸⁶Re) Obisbemeda 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. Rhenium (¹⁸⁶Re) Obisbemeda 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).
