livmoniplimab (ABBV-151) / AbbVie, argenx - LARVOL DELTA

Livmoniplimab with or without budigalimab in patients with advanced solid tumors: Results from the combination therapy in the urothelial carcinoma dose expansion cohort. (ASCO-GU 2024) - P1 | "Clinical Trial Registration Number: NCT03821935 Sponsored by AbbVie Background: Checkpoint inhibitors (CPIs) are approved for treating advanced urothelial carcinoma (UC). Livmo + budi had manageable safety and promising efficacy in pts with advanced UC that progressed on platinum-based therapy and a CPI. ORR in the UC cohort (pts postprogression with platinum + CPI therapy) are comparable with ORR in CPI-naive pts with pembrolizumab (KEYNOTE-045) and nivolumab (CheckMate 275) monotherapy. A subpopulation of pts in the UC cohort had a durable response to livmo + budi."

Anti-tumor T cell response and immunoselection under combined GARP:TGF-_1/PD-1 blockade (ESMO-IO 2024) - "Background Livmoniplimab (livmo) is a monoclonal anti-GARP:TGF-β1 antibody currently tested in combination with budigalimab (budi) in phase 1 and 2 trials for several cancer indications. Increase in the frequency of the two anti-BLZF1mut T cell clones after one cycle of treatment correlated with a reduction in the ratio of mutated BLZF1 to mutated TP53 alleles in the metastasis, suggesting increased cytotoxic activity and immunoselection by the anti-BLZF1 oligoclonal T cell response in the course of treatment.Conclusions Our results indicate that tumor-infiltrating CD8 T cells against mutated antigens can be amplified in response to livmo + budi, and exert cytolytic activity and immunoselection on tumor cells expressing the cognate antigens. Given that all patients included were refractory to previous anti-PD(L)1 therapy, our data suggests that the biological anti-tumor activity observed in the biopsy from one patient results at least in part from the activity of livmo."
