Lung cancer drug trial stopped early — too few patients to know if it works

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key inclusion criteria: 1. Adult ≥ 18 years of age at the time of informed consent. 2. Histologically confirmed NSCLC Stage IB-IIIA, N2 and selected IIIB (T3N2 or T4N2) (per AJCC 8th edition), deemed suitable for primary resection by treating surgeon (T4 tumors with mediastinal organ invasion were not eligible for enrollment). 3. Participant must have MET exon 14 mutation and/or high-level MET amplification (MET: GCN ≥ 10) as determined by a CLIA certified laboratory. High level MET amplification must be identified by FISH in a CLIA certified laboratory or FoundationOne CDx NGS (other NGS-based methods without adjusting for tumor content % cannot be accepted). 4. Participants must be eligible for surgery and scheduled for surgical resection within approximately 2 weeks after the last dose of neoadjuvant study treatment. 5. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1. Key exclusion criteria: 1. Participants with unresectable or metastatic disease. All participants should have brain imaging (either MRI brain or CT brain with contrast) prior to enrollment to exclude brain metastasis. 2. Presence or history of a malignant disease that has been diagnosed and/or required therapy within the past 3 years. Exceptions to this exclusion include the following: completely resected basal cell and squamous cell skin cancers, and completely resected carcinoma in situ of any type. 3. Prior treatment with any MET inhibitor or HGF-targeting therapy. 4. Participants with other known oncogenic driver alterations. 5. Prior systemic anti-cancer therapy (chemotherapy, immunotherapy, biologic therapy, vaccine) or investigational agents for NSCLC. 6. Participants with known hypersensitivity to capmatinib and any of the excipients of capmatinib (crospovidone, mannitol, microcrystalline cellulose, povidone, sodium lauryl sulfate, magnesium stearate, colloidal silicon dioxide, and various coating premixes). Other protocol-defined inclusion/exclusion criteria may apply at the end
