Patient case: 50-year-old male with prostate cancer; genetic feature: ATM deletion

Clinical trial: Ph II Trial of Carboplatin and Pemetrexed With or Without AZD1775 for Untreated Lung Cancer

Summary: The aim of this study is to combine AZD1775 with standard front-line chemotherapy in subjects with advanced NSCLC.

Detailed description: This is a randomised, phase II trial comparing AZD1775 plus pemetrexed and carboplatin followed by maintenance AZD1775 and pemetrexed versus pemetrexed and carboplatin followed by maintenance pemetrexed in patients with previously untreated metastatic non-squamous NSCLC with TP53 mutations. The primary endpoint of the trial is assessment of progression-free survival (PFS).
