- Study to assess new camptothecin-peptide conjugates for the treatment of sortilin-positive colorectal cancers
- Separate data to highlight activity of sudocetaxel zendusortide (TH1902) to trigger the cGAS/STING pathway potentiate and anti-PD-L1 immunotherapy tumor cell killing
MONTREAL, March 28, 2024 (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 two posters will be presented at the American Association for Cancer Research (AACR) Annual Meeting 2024, demonstrating the potential of its SORT1+ Technology™ platform – including novel camptothecin-peptide conjugates and its lead investigational peptide drug conjugate (PDC) candidate, sudocetaxel zendusortide (TH1902), as anticancer treatments. The AACR meeting is taking place April 5-10 in San Diego, CA.
These preclinical presentations reinforce existing data for sudocetaxel zendusortide to activate anti-PD-L1 immunotherapy tumor cell killing in SORT+1 cancers and provide the first evidence for novel camptothecin-peptide conjugates in the treatment of SORT+1 colorectal cancers.
“The studies we are presenting at the AACR 2024 meeting highlight the significant advancements made on our SORT+1 Technology™ platform through careful assessment of investigational compounds, including sudocetaxel zendusortide, which is currently being evaluated in a Phase 1 trial in patients with advanced ovarian cancer,” said Christian Marsolais, Ph.D., Senior Vice President and Chief Medical Officer of Theratechnologies. “These data showcase the potential of our PDC candidates with different payloads as potential future treatment options for a broad range of cancer types.”
Theratechnologies will present the following data at AACR 2024:

About Sudocetaxel Zendusortide (TH1902) and SORT1+ Technology™
Sudocetaxel zendusortide is a first-of-its-kind sortilin receptor (SORT1)-targeting PDC, and the first compound to emerge from the Company’s broader licensed oncology platform. A new chemical entity, sudocetaxel zendusortide employs a cleavable linker to conjugate (attach) a proprietary peptide to docetaxel, a well-established cytotoxic chemotherapeutic 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 has established the SORT1+ TechnologyTM platform as an engine for the development of PDCs that target SORT1, which is expressed in multiple tumor types. SORT1 is a “scavenger” receptor that plays a significant role in protein internalization, sorting, and trafficking. Expression of SORT1 is associated with aggressive disease, poor prognosis, and decreased survival. It is estimated that SORT1 is expressed in 40% to 90% of endometrial, ovarian, colorectal, triple-negative breast (TNBC), and pancreatic cancers, making this receptor an attractive target for anticancer drug development.

You can identify forward-looking statements by terms such as “may”, “will”, “should”, “could”, “promising”, “would”, “outlook”, “believe”, “plan”, “envisage”, “anticipate”, “expect” and “estimate”, or the negatives of these terms, or variations of them. The Forward-Looking Statements contained in this press release include, but are not limited to, statements regarding the development of multiple PDCs, including sudocetaxel zendusortide, their use and the potential benefits to be derived from their use. Although the Forward-Looking Statements contained in this press release are based upon what the Company believes are reasonable assumptions in light of the information currently available, investors are cautioned against placing undue reliance on these statements since actual results may vary from the Forward-Looking Statements contained in this press release. These assumptions include, without limitation, that the Company’s Phase 1 clinical trial using sudocetaxel zendusortide will be successful, that signs of efficacy will be observed in such Phase 1 clinical trial and no untoward side effects will be reported, and that the findings observed from the preclinical work conducted on new PDCs will be replicated into human subjects. Forward-Looking Statements assumptions are subject to a number of risks and uncertainties, many of which are beyond the Company’s control, that could cause actual results to differ materially from those that are disclosed in or implied by such Forward-Looking Statements. These risks and uncertainties include, but are not limited to, the lack of observation of strong efficacy results from the Phase 1 clinical trial using sudocetaxel zendusortide, the reporting of adverse side effects from the use of sudocetaxel zendusortide leading to a halt of the clinical trial, and that the findings observed from preclinical work conducted on new PDCs are not observed when those are administered into human subjects. We refer current and potential investors to the “Risk Factors” section (Item 3.D) of our Form 20-F dated February 21, 2024, available on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov under Theratechnologies’ public filings.
