XZP-5809-TT1 Tablets in Patients With T790M Mutation-positive Locally Advanced or Metastatic Non-small Cell Lung Cancer

Phase 1

Terminated

• Conditions: Non Small Cell Lung Cancer
• Interventions: Drug: XZP-5809-TT1 Tablet

• Registration Number: NCT04622072
• Lead Sponsor: Sihuan Pharmaceutical Holdings Group Ltd.

Brief Summary

The trial is divided into two parts, one is dose escalation phase, the second one is dose expansion phase.

For dose escalation phase, the main purpose is to evaluate safety and tolerability of XZP-5809-TT1 tablets after treatment with epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) in patients With T790M Mutation-positive Locally Advanced or Metastatic Non-small Cell Lung Cancer, and to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT).

For dose expansion phase, the main purpose is to evaluate Objective response rate (ORR) in patients With T790M Mutation-positive Locally Advanced or Metastatic Non-small Cell Lung Cancer.
