Experimental: Dacomitinib and Osimertinib
Patients will begin on combination dacomitinib and osimertinib at the prescribed doses. A cycle will be 28 days in duration. The study will use a standard 3+3 dose escalation design. Per MD discretion, telemedicine visits may be utilized for cycles where imaging is not collected, and physical exam, vital sign and labs collection will only be required concurrent with imaging visits. |
Drug: Dacomitinib
Dose level 1 Dacomitinib, Dose level 2 Dacomitinib, Dose level 3 Dacomitinib. Three patients will need to be enrolled at each dose level and assessed for DLT for 1 full cycle (28 days for cycle 1) before dose escalation decision is made. Drug: Osimertinib Dose level 1, 2 and 3 Osimertinib 40mg daily. Three patients will need to be enrolled at each dose level and assessed for DLT for 1 full cycle (28 days for cycle 1) before dose escalation decision is made. |
- maximum tolerated dose [ Time Frame: 1 year ]The MTD will be defined as the highest dose at which not more than 1/6 of the patients experience dose limiting toxicity (DLT). DLT is defined as any of the toxicity events described below that occurs within cycle 1 of treatment with the combination of dacomitinib and osimertinib.
- Best overall response rate [ Time Frame: 1 year ]Tumor response will be assessed using RECIST 1.1.The NCI Common Terminology Criteria for Adverse Events Version 5 (NCI-CTCAE) will be used to grade toxicities during the trial. Dose-limiting toxicities (DLT"s) are defined as any of the following events occurring during the first cycle of treatment
