Kestrel Therapeutics has begun a Phase 1 study in patients with advanced/metastatic solid tumors, including pancreatic ductal adenocarcinoma (PDAC), colorectal cancer (CRC), and non-small cell lung cancer (NSCLC), with KRAS mutations following clearance of the KST-6051 IND by the US Food and Drug Administration.
KST-6051 is a potential best-in-class, oral pan-KRAS inhibitor which is being developed for the treatment of advanced malignancies. KST-6051 is a potent and selective inhibitor of KRAS, with balanced activity against KRAS in the active (GTP-bound) and inactive (GDP-bound) states, that has consistently demonstrated on-target pathway modulation and anti-proliferative activity in several KRAS-dependent cancer cell lines. Once daily, oral administration of KST-6051 has similarly been shown to lead to robust activity at well tolerated doses in multiple human KRAS-dependent tumor models. KST-6051 has been shown to be well tolerated at relevant doses in multiple species.
