Abstract 1394TiP
Background
KRAS mutations are one of the most common oncogenic driver mutations in NSCLC, with the KRAS G12C mutation occurring in ∼14% of patients with lung adenocarcinoma. Adagrasib selectively and irreversibly inhibits KRASG12C, exhibiting favorable properties including long half-life (23 hrs), dose-dependent pharmacokinetics (PK), and brain penetrance. Studies in mutant KRAS G12C tumor models suggest that adagrasib enhances susceptibility to anti-PD-(L)1 immunotherapy by reconditioning the tumor immune microenvironment. In the phase 2 portion of the KRYSTAL-7 trial (NCT04613596), the combination of adagrasib and pembrolizumab (anti-PD-1 therapy) demonstrated encouraging efficacy in patients with previously untreated KRAS G12C-mutated NSCLC, particularly in patients with PD-L1 tumor proportion score (TPS) ≥50% (objective response rate 63%, disease control rate 84%, and 12-month progression-free survival [PFS] rate 60.8%), and had a manageable safety profile. Based on these preliminary data, the phase 3 study comparing first-line adagrasib plus pembrolizumab versus pembrolizumab alone in patients with KRAS G12C-mutated NSCLC and PD-L1 TPS ≥50% was initiated.
Trial design
The phase 3 portion of the KRYSTAL-7 study is a global, open-label, randomized trial comparing the efficacy and safety of first-line adagrasib (400 mg BID until disease progression) plus pembrolizumab (200 mg Q3W up to 35 cycles) versus pembrolizumab alone (200 mg Q3W up to 35 cycles) in patients with unresectable, locally advanced or metastatic KRAS G12C-mutated NSCLC (squamous or nonsquamous) and PD-L1 TPS ≥50%. Patients will be randomized 1:1 to each treatment arm and stratified according to known history of treated or untreated brain metastases (yes versus no), region (Asia Pacific versus non-Asia Pacific), and Eastern Cooperative Oncology Group performance status (0 versus 1). The primary endpoints are PFS by blinded independent central review and overall survival. Secondary endpoints include safety and tolerability, tumor response, adagrasib PK, and health-related quality of life. KRYSTAL-7 is currently open for enrollment.
