TGRX-326 Pharmacokinetic Drug Interaction

Phase 1
Completed
Conditions
Non Small Cell Lung Cancer
Interventions
Drug: Efavirenz+TGRX-326
Drug: Itraconazole+TGRX-326
Registration Number
NCT06294561
Lead Sponsor
Shenzhen TargetRx, Inc.
Brief Summary

This is a drug-drug interaction study for TGRX-326 to evaluate the effects of CYP3A inhibitor/inducer drugs on pharmacokinetic profiles of TGRX-326, an ALK inhibitor indicated for treatment of Non-small cell lung cancer.

Detailed Description

This study is designed as an open-label, single sequence, self-controlled study. The study will be conducted for 2 cycles, 10 days per cycle. Itraconazole, a CYP3A inhibitor, and Efavirenz, a CYP3A inducer, will be administrated orally with TGRX-326 to evaluate the effect of these drugs on the pharmacokinetic profiles of TGRX-326. Pharmacokinetic parameters will be evaluated as primary endpoints. Safety evaluation will also be conducted.
