Portage Biotech Announces Presentation of PORT-5 (STI-001) Late-Breaking Data at AACR 2022 Annual Meeting

Preclinical data will be presented in a late-breaking abstract session

WESTPORT, Conn., March 09, 2022 (GLOBE NEWSWIRE) — Portage Biotech Inc. (NASDAQ: PRTG) (“Portage” or the “Company”), a clinical-stage immuno-oncology company developing therapies to improve patient lives and increase survival by avoiding and overcoming cancer treatment resistance, and Stimunity, an early-stage biotech company focused on the development of a unique STING agonist based on virus-like particles, today announced data from a collaboration on a STING-activating therapy, PORT-5 (STI-001) will be presented at the American Association for Cancer Research (AACR) 2022 Annual Meeting taking place April 8-13, 2022, in New Orleans, Louisiana.

“The stimulator of interferon genes (STING) pathway is a well-recognized immune-boosting pathway and has long been an area of interest in cancer treatment, but STING-activating therapies have historically been limited in clinical trials due to delivery challenges,” said Dr. Ian Walters, chief executive officer of Portage. “We are grateful that the scientific committee found the research on our systemically delivered STING-based therapy, PORT-5, to be highly significant and timely to be included in the late-breaking session for AACR and look forward to sharing further updates in the coming months.”

About PORT-5 (STI-001)
PORT-5 offers a potentially first-in-class approach to developing molecules that activate the STING pathway by packaging a STING agonist in a virus-like particle (VLP), a well-tested delivery system that can be customized and targeted to specific cells. The therapy can be administered systemically yet stimulates a targeted and specific immune activation. One or more targeted agents can be packaged within the VLP to enhance its potency. PORT-5 is currently in preclinical studies and is being advanced in collaboration with Stimunity and the Institut Curie.
