Phase 1b Study of Dato-DXd in Combination With Immunotherapy With or Without Carboplatin in Advanced or Metastatic Non-Small Cell Lung Cancer

The primary objective is to assess the safety and tolerability of Dato-DXd in combination with immunotherapy with or without 4 cycles of carboplatin in participants with advanced or metastatic NSCLC. Two dose levels of Dato-DXd will be studied in combination with immunotherapy (durvalumab, AZD2936, MEDI5752, or AZD7789) with or without 4 cycles of carboplatin in 15 study cohorts Each cohort will start with Part 1 (dose escalation or confirmation), where 3 to 9 participants will be assessed for dose-limiting toxicities (DLT) in the first cycle of treatment. if the DLT incidence rate meets the criteria based on the modified toxicity probability interval-2 (mTPI-2), then Part 2 (dose expansion) may be opened.
