Experimental: Phase 1: Dose Exploration The recommended phase 2 target dose (RP2D) of tarlatamab in combination with AMG 404 will be estimated using a modified toxicity probability interval (mTPI-2) design. A combination RP2D may be identified based on emerging safety, efficacy, and pharmacodynamic data prior to reaching an maximum tolerated dose (MTD). |
Drug: Tarlatamab
Tarlatamab will be administered as an intravenous (IV) infusion.
Other Names:
Drug: AMG 404
AMG 404 will be administered as an intravenous (IV) infusion.

Experimental: Phase 2: Dose Expansion Participants will receive the RP2D of tarlatamab in combination with AMG 404 identified in Phase 1 (dose exploration) of the study. |
Drug: Tarlatamab
Tarlatamab will be administered as an intravenous (IV) infusion.
Other Names:
Drug: AMG 404
AMG 404 will be administered as an intravenous (IV) infusion.
