Phase II of Neoadjuvant and Adjuvant Capmatinib in NSCLC
- Registration Number
- NCT04926831
- Lead Sponsor
- Novartis Pharmaceuticals
- Brief Summary
This study was planned to determine if neoadjuvant capmatinib could improve the major pathological response (MPR) in patients with Stage IB-IIIA, N2 and selected IIIB (T3N2 or T4N2) lung cancers with Mesenchymal Epithelial Transition (MET) exon 14 mutations and/or high MET amplification beyond those achieved with surgery, chemotherapy, and radiation. Treatment was to be continued with capmatinib in the adjuvant setting to evaluate the potential clinical benefit of extended therapy.
The purpose of this study is to determine if neoadjuvant capmatinib can improve outcomes in participants with stages I-IIIA non-small cell lung cancer with MET exon 14 mutations and/or high MET amplification beyond those achieved with surgery, chemotherapy, and radiation.
- Detailed Description
This was a Phase II, two cohort, two stage study of capmatinib given for 8 weeks (2 cycles) prior to surgical resection, followed by three-year capmatinib treatment in adjuvant setting. Surgery had to be performed up to 2 weeks after the last dose of neoadjuvant study treatment.
There were 2 molecularly defined cohorts enrolled in parallel:
* Cohort A: MET exon 14 skipping mutations, irrespective of MET GCN or
* Cohort B: high level MET amplification (MET: GCN ≥ 10 by FISH or FoundationOne CDx NGS using tumor tissue).
Approximately 42 participants were aimed to be enrolled in the study, with 21 participants per cohort. This was planned to obtain 38 evaluable participants, 19 per each cohort. Participants who had both MET exon 14 skipping mutations and high-level MET amplification were planned to be enrolled into Cohort A. An evaluable subject received the neoadjuvant treatment and subsequently underwent surgery, resulting in a pathological response.
The study recruitment was prematurely discontinued due to significant recruitment challenges leading to termination of the study. The challenges included the rarity of the mutation and site initiation delays caused by staff shortages associated with COVID-19. As a result, only 4 subjects were enrolled and treated in Cohort A.

Group Intervention Description Cohort A (MET exon 14 skipping mutations) capmatinib The study treatment started on Cycle 1 Day 1 with the first administration of capmatinib 400 mg twice a day (b.i.d.). The participants were planned to receive study treatment for a maximum of 3 years following surgery or until early discontinuation. Cohort B (high MET amplification) capmatinib The study treatment started on Cycle 1 Day 1 with the first administration of capmatinib 400 mg twice a day (b.i.d.). The participants were planned to receive study treatment for a maximum of 3 years following surgery or until early discontinuation.
- Primary Outcome Measures
Name Time Method Major Pathological Response (MPR) Rate Baseline up to time of surgery (approximately 8 to 10 weeks after first dose) The primary efficacy variable was MPR rate, defined as the proportion of participants with ≤ 10% residual viable cancer cells. MPR rate was to be assessed via local review for primary analysis. MPR assessment in tumor samples was collected at time of resection.
Due to low number of participants and limited data, analysis related to the primary endpoint was not performed.
- Secondary Outcome Measures
Name Time Method Overall Response Rate (ORR) Baseline up to time of surgery (approximately 8 - 10 weeks after first dose) Overall Response Rate (ORR) was defined as the percentage participants with Best Overall Response (BOR) of Complete Response (CR) or Partial Response ( PR) according to RECIST v1.1. BOR was the observed response at the assessment performed prior to surgery via local review.
Complete Pathologic Response (pCR) Rate Baseline up to time of surgery (approximately. 8- 10 weeks after first dose) Complete pathologic response (pCR) rate ws defined as the percentage of participants with no residual viable cancer cells. pCR rate was assessed via both central and local review.
Disease Free Survival (DFS) From time of surgery to Months 24, 36, and 60 Disease Free Survival (DFS) was defined as the time from the date of first adjuvant treatment to the date of the first documented disease recurrence as assessed by local investigator radiologically or death due to any cause. In case of non-conclusive radiological evidence, a biopsy was to be performed to confirm recurrence and used as DFS event. DFS events were assessed locally.
Number of Adverse Events and Serious Adverse Events as Assessed by CTCAE Criteria Baseline up to 30 days after last dose of study medication, assessed up to approximately 20 months An adverse event (AE) is any untoward medical occurrence (e.g. any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a clinical investigation participant after providing written informed consent for participation in the study. Therefore, an AE may or may not be temporally or causally associated with the use of a medicinal (investigational) product.
Treatment emergent Adverse Event (TEAEs) in this study were events that started after the first dose of study treatment and until 30 days after the last dose of study treatment, or events present prior to the first dose of treatment which increased in severity based on preferred term within 30 days after the last study treatment.
