The goal of this phase II clinical trial is to evaluate the intracranial efficacy of JDQ443, a KRAS G12C inhibitor in patients with KRAS G12C+ NSCLC and brain metastases (cohort A: asymptomatic, untreated brain metastases, cohort B: asymptomatic, treated brain metastases). The main question it aims to answer is to evaluate the intracranial efficacy, according to RANO-BM criteria, in patients with asymptomatic and untreated brain metastases.
Participants will receive JDQ443 200 mg BID until unacceptable toxicity or disease progression.
