Study of Dacomitinib and Osimertinib for Patients With Advanced EGFR Mutant Lung Cancer

• Status: Active, not recruiting
• Trial end date: 2022-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to test the safety of dacomitinib and osimertinib, at increasing doses, to find out what effects, if any, this combination of drugs has on people with metastatic EGFR mutant lung cancer that has not been treated with an EGFR TKI.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Memorial Sloan Kettering Cancer Center
• Treatments: Osimertinib
