This study will evaluate two study drugs called ubamatamab and REGN7075, to see if they can help treat advanced or metastatic Non-Small Cell Lung Cancer (NSCLC), and sarilumab, to evaluate to see if it can help with immune-related side effects from ubamatamab. The study is looking at: * How well ubamatamab and REGN7075 works * The side effects that ubamatamab and REGN7075 might cause * How much ubamatamab and REGN7075 is in the blood at different times * If the body makes antibodies to ubamatamab and/or REGN7075, this may cause the ubamatamab to not work as well
