Not yet recruiting

• Conditions: NSCLC; MET Exon 14 Mutation; BRAF V600 Mutation
• Interventions: Drug: Dabrafenib + Trametinib; Drug: Capmatinib

• Registration Number: NCT06054191
• Lead Sponsor: Sun Yat-sen University

Brief Summary

This is a Phase II, two parallel group study assessing the efficacy and safety of neoadjuvant and adjuvant targeted therapy in patients with stage IB-IIIA NSCLC harboring BRAF V600 or MET exon14 mutations.

Detailed Description

This is a Phase II, two parallel group study assessing the efficacy and safety of neoadjuvant and adjuvant targeted therapy in patients with stage IB-IIIA NSCLC harboring BRAF V600 or MET exon14 mutations. Eligible patients with BRAF V600 mutations will receive dabrafenib 150mg bid plus trametinib 2mg qd for 8 weeks before a surgical resection (neoadjuvant), and followed by up to 4 cycles of adjuvant chemotherapy, if receive adjuvant chemotherapy, up to four cycles, chemo regimen according to investigators' choice, and up to 2 years of adjuvant targeted therapy with dabrafenib plus trametinib. For patients with MET exon14 mutations, they will receive capmatinib 400mg bid for 8 weeks before surgery (neoadjuvant), followed by up to 4 cycles of adjuvant chemotherapy, about adjuvant chemotherapy same as BRAF V600 group, and up to 2 years of adjuvant targeted therapy with capmatinib post-surgery. During treatment, patients will visit their physicians regularly for disease and safety assessment. After the end of treatment, survival follow-up will be conducted every 3 months for up to 3 years. Approximately 40 evaluable patients will be enrolled in the study (20 patients in each cohort).

• History of current interstitial lung disease or pneumonitis.
• Patients with conditions requiring systemic corticosteroids (>10 mg daily prednisone or equivalent) or immunosuppressive medication within 14 days of the first dose of study drug (Inhaled or topical steroids and adrenal-replacement steroids are allowed).
• History of other malignancies within 5 years (excluding basal cell carcinoma of the skin or other carcinoma in situ that has been resected).
• Pregnant or lactating women.
• Those who are allergic to the research drug or its components.
• Subjects who are deemed unable to comply with the study requirements or complete the study.

Primary Outcome Measures

Name	Time	Method
Pathological complete response (pCR) rate	up to 2 years	pCR rate is defined as the percentage of participants with no residual viable tumor cells.

Secondary Outcome Measures

Name	Time	Method
Event-free survival (EFS)	up to 3 years	EFS is defined as the time from intervention to the first documented disease progression per RECIST v1.1 that precludes surgery, local or distant disease recurrence, or death from any cause, whichever occurs first.
Disease-free survival (DFS)	up to 3 years	DFS defined as the time from the end of surgery until recurrence or death due to any cause, DFS rate at 12, 24, 36 and 60 months.
Overall survival (OS)	up to 3 years	OS defined as the time between the date of enrollment and the date of death due to any cause.
