Efficacy and Safety of JMT101 Combined With Afatinib (or Osimertinib) in Patients With Non-Small Cell Lung Cancer

Phase 1
Conditions
Locally Advanced or Metastatic Non-Small Cell Lung Cancer
Interventions
Registration Number
NCT04448379
Lead Sponsor
Shanghai JMT-Bio Inc.
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.

GroupInterventionDescription
Dose Expansion CohortJMT101Once the effective dose has been determined, an expansion cohort will be opened to evaluate the efficacy and safety of the selected dose.
Dose Escalation CohortJMT101Two 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).
Primary Outcome Measures
NameTimeMethod
Incidence of adverse events (defined by the Common Terminology Criteria for Adverse Events version 5.0 (CTCAE V5.0)).From enrollment until 30 days after the last dose
Secondary Outcome Measures
NameTimeMethod
Progression free survival (PFS).From first dose to disease progression or end of study, an average of 1 year
Overall survival (OS).From first dose to death or end of study, an average of 1 year
Objective Response Rate (ORR) Assessed by Blinded Independent Review Committee (IRC) per RECIST Version 1.1From first dose to disease progression or end of study, an average of 1 year
Disease control rate (DCR).From first dose to disease progression or end of study, an average of 1 year
Half-life (T1/2) of JMT101.From enrollment until 30 days after the last dose
Immunogenicity profile of JMT101.From enrollment until 30 days after the last dose

Blood samples will be collected from subjects post treatment for assessment to detect the presence of anti-drug antibodies and neutralizing antibodies.

Area under the concentration curve from time 0 to the concentration at last time point (AUC0-last) of JMT101.From enrollment until 30 days after the last dose
Maximum measured plasma concentration (Cmax) of JMT101.From enrollment until 30 days after the last dose
Time to maximum plasma concentration (Tmax) of JMT101.From enrollment until 30 days after the last dose
Potential biomarkers detected in plasma circulating tumor DNA.From enrollment up to disease progression, an average of 1 year
