MONTREAL, Aug. 30, 2023 (GLOBE NEWSWIRE) — Theratechnologies Inc. (“Theratechnologies” or the “Company”) (TSX: TH) (NASDAQ: THTX), a biopharmaceutical company focused on the development and commercialization of innovative therapies, today announced that all five of the U.S.-based clinical sites participating in the conduct of the Phase 1 clinical trial of the Company’s lead investigational peptide drug conjugate, sudocetaxel zendusortide, are now activated to screen, enroll and dose advanced ovarian cancer patients.

About Sudocetaxel Zendusortide and SORT1+ Technology™

Sudocetaxel zendusortide is currently Theratechnologies’ lead investigational peptide drug conjugate candidate for the treatment of cancer derived from its SORT1+ Technology™. It is the Company’s proprietary peptide linked to docetaxel – a commonly used cytotoxic agent used to treat many cancers. The FDA granted fast track designation to sudocetaxel zendusortide as a single agent for the treatment of all sortilin-positive recurrent advanced solid tumors that are refractory to standard therapy. Sudocetaxel zendusortide is currently being evaluated in a phase 1 clinical trial.

Theratechnologies is currently developing a platform of proprietary peptides called SORT1+ Technology™ for cancer drug development targeting SORT1 receptors. The SORT1 receptor plays a significant role in protein internalization, sorting and trafficking. It is highly expressed in cancer cells compared to healthy tissue, which makes SORT1 an attractive target for cancer drug development. Expression of SORT1 is associated with aggressive disease, poor prognosis and decreased survival. It is estimated that the SORT1 receptor is expressed in 40% to 90% of cases of endometrial, ovarian, colorectal, triple-negative breast and pancreatic cancers.
