- •Participants with untreated asymptomatic brain metastases smaller or equal to 2 cm in size (per lesion if more than one) and not requiring corticosteroid treatment are eligible.
Exclusion Criteria
- •Disease Related
- •Tumors harboring the following mutations amenable to targeted therapies: epidermal growth factor receptor (EGFR), ALK receptor tyrosine kinase (ALK), ROS proto-oncogene 1 (ROS1), neurotrophic tyrosine receptor kinase (NTRK), MET proto-oncogene (MET), B-Raf proto-oncogene (BRAF), RET proto-oncogene (RET), Human epidermal growth factor receptor 2 (HER2/ERBB2), KRAS proto-oncogene G12C (KRAS G12C).

Arms & Interventions
Part 1: Dose Evaluation
Participants will be randomized to receive one of 2 active dose levels of AMG 193 orally (PO) daily (QD) in 28 days cycles. Part 1 of the study will determine the recommended phase 2 dose (RP2D).
Intervention: AMG 193
Part 2: Dose Expansion
Participants will receive AMG 193 PO QD in 28-day cycles at the RP2D.
Intervention: AMG 193
