BMS986260是一种口服有活力的选择性TGFβR1抑制剂，是免疫肿瘤学药物。它能够抑制 MINK 和 NHLF 细胞系中 TGFβ 介导的 pSMAD2/3 核转位，IC50值分别为 350 nM 和 190 nM。它对 TGFβR1 的选择比 TGFβR2 同功酶高。

BMS-986260 is a selective, and orally bioavailable TGFβR1 inhibitor(IC50 = 1.6 nM).

BMS-986260 demonstrated functional activity in multiple TGFβ-dependent cellular assays, excellent kinome selectivity, favorable pharmacokinetic properties, and curative in vivo efficacy in combination with anti-PD-1 antibody in murine colorectal cancer (CRC) models. Since daily dosing of TGFβR1 inhibitors is known to cause class-based cardiovascular (CV) toxicities in preclinical species, a dosing holiday schedule in the anti-PD-1 combination efficacy studies was explored. An intermittent dosing regimen of 3 days on and 4 days off allowed mitigation of CV toxicities in one month dog and rat toxicology studies and also provided similar efficacy as once daily dosing.
