Randomized, Open-Label Phase Ib/Ii Study Of Atezolizumab With Or Without Daratumumab In Previously Treated Advanced Or Metastatic Non-Small Cell Lung Cancer (Nsclc).

TPS9102Background: Daratumumab (DARA), a human CD38 monoclonal antibody, is approved for treatment of relapsed/refractory multiple myeloma (RRMM). DARA produces deep clinical responses in RRMM and induces T-cell expansion through reduction of immune suppressive cell populations (CD38+ myeloid-derived suppressor cells and regulatory T and B cells). Atezolizumab (atezo) blocks programmed death-ligand 1 (PD-L1) and was recently approved for metastatic NSCLC that progressed on or during platinum therapy based on data showing improved overall survival (OS) in the atezo vs docetaxel treatment arm. A combination of DARA and atezo may improve clinical responses in NSCLC by enhancing anti-tumor T-cell responses facilitated by checkpoint inhibition. This study will assess the anti-tumor activity and safety profile of DARA plus atezo vs atezo alone in patients (pts) with previously treated advanced or metastatic NSCLC. Methods: This is an ongoing phase 1b/2 randomized, open-label, multicenter study of atezo (1200 mg...
