This phase III study is designed to evaluate the anticancer activity of capmatinib in combination with osimertinib compared to platinum-pemetrexed based doublet chemotherapy as second line treatment in patients with advanced or metastatic non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutation, T790M negative, mesenchymal-to-epithelial transition factor (MET) amplified who progressed following EGFR tyrosine kinase inhibitors (TKIs). The randomized part will be preceded by a safety run-in part in which the recommended dose of the combination of capmatinib and osimertinib will be confirmed.
A Phase III Randomized, Controlled, Open-label, Multicenter, Global Study of Capmatinib in Combination With Osimertinib Versus Platinum - Pemetrexed Based Doublet Chemotherapy in Patients With Locally Advanced or Metastatic NSCLC Harboring EGFR Activating Mutations Who Have Progressed on Prior Generation EGFR-TKI Therapy and Whose Tumors Are T790M Mutation Negative and Harbor MET Amplification (GEOMETRY-E)
This is a multicenter, open-label, randomized, active-controlled, global phase III study that will enroll adult participants with locally advanced or metastatic NSCLC with EGFR activating mutation, T790M negative, MET amplified who have progressed following EGFR TKIs. The study will consist of an initial safety run-in part to evaluate the safety and tolerability of capmatinib in combination with osimertinib and to confirm the recommended dose for the randomized part, and a randomized part that will evaluate the efficacy and safety of capmatinib in combination with osimertinib compared to platinum (cisplatin or carboplatin) - pemetrexed doublet based chemotherapy as second line treatment. Participant's respective treatment (either with capmatinib in combination with osimertinib, or with platinum (cisplatin or carboplatin) - pemetrexed based doublet chemotherapy) will be continued until participant experiences any of the following: documented disease progression by Response Evaluation Criteria In Solid Tumors 1.1 (RECIST 1.1) (as assessed by the investigator in the run-in part, and as assessed by the investigator confirmed by blinded independent review committee (BIRC) in the randomization part), withdrawal of consent, pregnancy, lost to follow-up, or death. Participants who progressed in the platinum-pemetrexed arm will be allowed to crossover to capmatinib in combination with osimertinib therapy after BIRC confirmed, RECIST 1.1-defined progressive disease. Study treatment may be continued beyond initial disease progression as per RECIST 1.1 if, in the judgement of the investigator, there is evidence of clinical benefit, and the participant wishes to continue on the study treatment. After treatment discontinuation, all participants will be followed for safety evaluations during the safety follow-up period.
