INCB99280 / Incyte - LARVOL DELTA

Phase I safety, efficacy, and biomarker response evaluations of three oral PD-L1 inhibitors: INCB086550, INCB099280, and INCB099318. (PubMed, J Immunother Cancer) - P1 | "Both INCB099280 and INCB099318 had an acceptable safety profile, with preliminary evidence of antitumor activity. The risk of immune-mediated neuropathy led to discontinuation of the clinical program for INCB086550."

The overall sample size Will be of 30 pts. Secondary endpoints will include safety (CTCAE v.5.0), event-free survival, bladder-intact overall survival (OS) and OS (EUCT number: 2024-511029-73-00)."

Incyte drops pair of PD-L1 drugs as part of 2nd pipeline clear-out this year (FierceBiotech) - "The latest list of discontinued assets includes both of Incyte’s oral, small-molecule PD-L1 inhibitors that were being assessed in phase 1 trials. One of these, INCB99280, was being evaluated in an early-stage solid tumor trial, and the biotech had already set out plans for a phase 1/1b trial in KRASG12C-mutated solid tumors in combination with Bristol Myers Squibb’s Krazati. The other scrapped PD-L1 inhibitor, dubbed INCB99318, was also in a phase 1 solid tumor trial. Also on the chopping block are a couple of LAG3 drug candidates. One of these is a LAG-3 monoclonal antibody dubbed INCAGN2385 that was being developed with Agenus. The other was a bispecific anti–PD1 and anti–LAG-3 antibody dubbed INCA32459 that was being developed with Merus and had undergone a phase 1 study in select advanced malignancies....Finally, Incyte has removed a TIM-3 monoclonal antibody dubbed INCAGN2390, which was another product of the Merus collaboration."

A phase 1 study of the small-molecule PD-L1 inhibitor INCB099280 in select advanced solid tumors: Updated safety, efficacy, and pharmacokinetics (PK) results. (ASCO 2024) - P1 | "INCB099280 was generally well tolerated at all doses tested and showed promising antitumor activity. INCB099280 PK was dose proportional up to 800 mg bid, with high variability; steady-state trough exposure exceeded IC90 for ≥300 bid doses. These data support further development of INCB099280 as monotherapy and in combination regimens for solid tumors."
