2 Clinical Trials for Various Conditions
Primary Objective: * Safety run-in part: to assess the tolerability and to determine the recommended doses of tusamitamab ravtansine in combination with pembrolizumab and tusamitamab ravtansine in combination with pembrolizumab and platinum-based chemotherapy with or without pemetrexed to be tested in the expansion part of the study in the NSQ NSCLC population * Expansion part (including participants treated at the recommended dose for expansion \[RDE\] from the Safety Run-in part): to assess the antitumor activity of several dose levels (DLs; if applicable) of tusamitamab ravtansine in combination with pembrolizumab and of several DLs of tusamitamab ravtansine in combination with pembrolizumab, platinum-based chemotherapy, and pemetrexed in the NSQ NSCLC population Secondary Objectives: * To assess the safety and tolerability of several DLs (if applicable) of tusamitamab ravtansine in combination with pembrolizumab and of 1 DL of tusamitamab ravtansine in combination with pembrolizumab and platinum-based chemotherapy, and of several DLs of tusamitamab ravtansine in combination with pembrolizumab, and platinum-based chemotherapy with pemetrexed in the NSQ NSCLC population * To assess the antitumor activity of several DLs (if applicable) of tusamitamab ravtansine in combination with pembrolizumab and of 1 DL of tusamitamab ravtansine in combination with pembrolizumab and platinum-based chemotherapy, and of several DLs of tusamitamab ravtansine in combination with pembrolizumab, platinum-based chemotherapy, and pemetrexed in the NSQ NSCLC population * To assess the durability of the response to treatment with several DLs (if applicable) of tusamitamab ravtansine in combination with pembrolizumab and of 1 DL of tusamitamab ravtansine in combination with pembrolizumab and platinum-based chemotherapy, and of several DLs of tusamitamab ravtansine in combination with pembrolizumab and platinum-based chemotherapy, and pemetrexed in the NSQ NSCLC population * To assess the antitumor activity of tusamitamab ravtansine in combination with pembrolizumab and platinum-based chemotherapy in the NSQ NSCLC population * To assess the pharmacokinetics (PK) of tusamitamab ravtansine, pembrolizumab, pemetrexed, cisplatin, and carboplatin, each when given in combination as a doublet (tusamitamab ravtansine + pembrolizumab) or a triplet (tusamitamab ravtansine + pembrolizumab + platinum-based chemotherapy) or a quadruplet (tusamitamab ravtansine + pembrolizumab + platinum-based chemotherapy + pemetrexed) * To assess the immunogenicity of tusamitamab ravtansine in combination with pembrolizumab and tusamitamab ravtansine in combination with pembrolizumab and platinum based chemotherapy with or without pemetrexed
This is an open label single group, Phase 2, 1-arm study for treatment to evaluate efficacy, safety, and Pharmacokinetic (PK) of tusamitamab ravtansine in nonsquamous non-small-cell-lung-cancer (NSQ NSCLC) participants with negative or moderate CEACAM5 expression tumors and high circulating carcinoembryonic antigen (CEA). Participants who will be enrolled, will receive tusamitamab ravtansine as monotherapy every two weeks (Q2W) until disease progression, unacceptable adverse event (AE), initiation of a new anticancer therapy, or the participant's or investigator's decision to stop the treatment, whichever comes first. A total of approximately 38 participants are planned to be treated.
