Announcement
Theratechnologies Inc announced Phase 1 data demonstrating signs of long-term efficacy and a manageable safety profile of its lead investigational peptide drug conjugate (PDC) candidate, sudocetaxel zendusortide (TH1902), in patients with solid tumors.
AI Summary
Theratechnologies Inc announced promising Phase 1 trial data for its investigational peptide drug conjugate, sudocetaxel zendusortide (TH1902), in patients with solid tumors. The updated analysis from Parts 1 and 2 of the ongoing study showed signs of long-term efficacy, with durable disease stabilization lasting up to 45 weeks beyond treatment completion. These results suggest that TH1902 works through a unique, multimodal mechanism of action, which includes triggering immune responses and targeting chemotherapy-resistant cancer stem cells.
The safety profile of sudocetaxel zendusortide was found to be manageable at a 300mg/m2 dose, with few Grade 3 adverse events reported. Early efficacy signals were notably observed in female cancers, such as ovarian, endometrial, and triple-negative breast cancer. This encouraging data supports advancing to Part 3 of the Phase 1 trial focused on dose optimization.

AI Summary
Theratechnologies Inc. announced that it will present three research posters at IDWeek 2024, held in Los Angeles, California from October 16-19. The posters focus on important health issues faced by people with HIV. One poster highlights data linking excess visceral abdominal fat (EVAF) to a higher risk of cardiovascular disease. Another poster shows that tesamorelin—a growth hormone-releasing factor analog—can reduce EVAF and lower cardiovascular risk in HIV patients. A third poster details the study design and baseline characteristics of the PROMISE-US trial, which investigates ibalizumab in heavily treatment-experienced patients with multidrug-resistant HIV.
These presentations aim to provide new insights for clinicians and researchers into managing complications associated with long-term HIV treatment. The findings will be shared during scheduled sessions at IDWeek 2024, marking an important opportunity for advancing understanding of HIV-related health issues.
