Overview
Brief Summary
This study is a Phase Ib, open label, multi-center study of to evaluate the safety and efficacy of JMT101 combined with EGFR-TKIs (Afatinib or Osimertinib) in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring EGFR exon 20 insertion mutations.
Detailed Description
The objective of the trial is to evaluate the safety and efficacy of JMT101 combined with EGFR-TKIs (afatinib or osimertinib) in patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations. This study consists of two parts (Stage I and Stage II). Stage I was a dose escalation study, and Stage II was a dose expansion study.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Pathologically or cytologically confirmed, locally advanced or metastatic NSCLC, harboring an EGFR exon 20 insertion mutation. ( non-irradiable, non-operable);
- •No previous treatment or first-line treatment failed NSCLC;
- •At least 1 measurable lesion according to RECIST 1.1;
- •ECOG score 0 or 1;
Exclusion Criteria
- •Previously treated with EGFR antibody;
- •Symptomatic brain metastasis;
- •Interstitial pneumopathy;
- •Known hypersensitivity to any ingredient of JMT101, afatinib, osimertinib or their excipients;
- •Receiving an investigational product in another clinical study within 4 weeks;
- •History of serious systemic diseases;

- •Pregnancy or lactating women.
Arms & Interventions
Dose Escalation Cohort
Two dose levels of JMT101 combined with afatinib or osimertinib will be tested according to the "3 + 3" dose-escalation design. The dose-limiting toxicity (DLT) will be assessed from the first administration to the end of the first cycle (28 days).
Intervention: JMT101
Dose Expansion Cohort
Once the effective dose has been determined, an expansion cohort will be opened to evaluate the efficacy and safety of the selected dose.
Intervention: JMT101
