Study Overview
Brief Summary
This study will evaluate two study drugs called ubamatamab and marlotamig, 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 marlotamig work(s)
- The side effects that ubamatamab and marlotamig might cause
- How much ubamatamab and marlotamig is in the blood at different times
- If the body makes antibodies to ubamatamab and/or marlotamig, this may cause the ubamatamab to not work as well

Inclusion Criteria
- •Has histologically or cytologically confirmed diagnosis of advanced (stage IIIB not amenable to definitive chemoradiotherapy or stage IIIC) or metastatic (stage IV) NSCLC
- •Has received appropriate first line standard of care treatment for advanced or metastatic NSCLC, as described in the protocol
- •If platinum doublet chemotherapy was not administered as first line therapy, it is required in a later line of therapy prior to enrollment unless there is a documented reason why it is not appropriate
- •Has tumor tissue (archival or fresh) available for testing MUC16 expression by immunohistochemistry inclusion (IHC), as described in the protocol
- •Has at least 1 radiographically measurable lesion by Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) per RECIST v1.1 criteria. Target lesions may be located in a previously irradiated field if there is documented (radiographic) disease progression in that site
- •Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Exclusion Criteria
- •Has progression of disease fewer than 84 days from starting initial anti-Programmed Cell Death (PD)-(L) 1 therapy
- •Experienced toxicity related to prior treatment that has not resolved to grade 1 prior to initiation of study intervention (except alopecia, hearing loss, grade 2 neuropathy, or endocrinopathy managed with hormone replacement therapy)
- •Has untreated or active primary brain tumor, Central Nervous System (CNS) metastases, leptomeningeal disease, or spinal cord compression, as described in the protocol
- •Current participation OR past participation in another investigational study in which an investigational intervention (eg, drug, vaccine, invasive device) was administered within 4 weeks before planned first dose of study intervention in this clinical study
- •Has received prior monoclonal antibody against PD-(L)1 within 21 days of the first dose of study intervention
- •Has had other prior anti-cancer immunotherapy within 21 days prior to study intervention, as described in the protocol
- •Has received prior cytotoxic chemotherapy within 21 days of the first dose of study intervention
- •Has received an anti-EGFR antibody therapy within the following drug-specific window prior to first dose of study intervention (approximately 5 half-lives), as described in the protocol
- •NOTE: Other protocol defined inclusion / exclusion criteria apply
