Description:
The purpose of this study is to test the safety of combining Osimertinib with either
Cisplatin or Carboplatin (at different dose levels) and Etoposide, to find out what effects,
if any, this combination of drugs has on people with EGFR mutant lung cancer.

Osimertinib, Platinum (cisplatin or carboplatin) and Etoposide | Experimental | Initially, 6 patients will be enrolled and will begin treatment with osimertinib 80mg orally daily (3 who will be receiving cisplatin and 3 who will be receiving carboplatin). Cisplatin or carboplatin treatment will be decided by the treating physician prior to study registration. After 9 weeks (+/- 1 week)( 3 cycles) on osimertinib alone, carboplatin or cisplatin and etoposide will be added. Carboplatin is doses at an AUC of 5 or cisplatin at 60mg/m2 will be given on C4D1. Etoposide is dosed at 100mg/m2 given on Days 1-3 of C4. Only patients on osimertinib 80mg orally daily at the start of cycle 4 will be included in the 3+3 dose de-escalation portion of the study. Chemotherapy and osimertinib will be administered concurrently during cycles 4-7, and from cycle 8 onward, osimertinib monotherapy will be continued. Patients will present every 2 cycles post-chemo (Cycles 8, 10, 12, etc.) | - Osimertinib
