New Combination	NCT04538378 ↗	Olaparib (LYNPARZA) Plus Durvalumab (IMFINZI) in EGFR-Mutated Adenocarcinomas That Transform to Small Cell Lung Cancer (SCLC) and Other Neuroendocrine Tumors	Recruiting	National Cancer Institute (NCI)	Phase 2	2021-07-07	Background: Lung cancers with EGFR mutations may develop resistance to therapies targeting this protein by evolving/being transformed into small cell or neuroendocrine cancers. There are no standard treatments for it. Researchers want to see if a new combination of drugs can help. Objective: To see if the combination of durvalumab and olaparib will cause tumors to shrink. Eligibility: Adults age 18 and older who had EGFR-mutated non-small-cell lung carcinoma (NSCLC) that was treated and now transformed to SCLC or another neuroendocrine tumor. Design: Participants will be screened under a separate protocol. They may have a tumor biopsy. Participants will have a physical exam. They will have a review of their symptoms, their medicines, and their ability to do their normal activities. They will have blood tests. They will have an electrocardiogram to evaluate their heart. Participants will have a computed tomography (CT) scan, a series of x-rays taken of parts of the body. Participants will get durvalumab on Day 1 of each 28-day cycle. It is given through a small plastic tube that is put in an arm vein. They will take olaparib by mouth twice every day. They will keep a medicine diary. Participants will take the study drugs until their disease gets worse or they have unacceptable side effects. About 30 days after they stop taking the study drugs, participants will have a follow-up visit. Then they will be contacted every 6 months for the rest of their life....
