Experimental: Part 2a, Phase 1: AMG 193 Dose Exploration + Docetaxel - Participants with MTAP-null NSCLC will receive escalating doses of AMG 193 + a fixed dose of docetaxel to estimate the MTD/RP2D of the combination.

Experimental: Part 2b, Phase 1: AMG 193 + Docetaxel Dose Expansion - Participants with MTAP-null NSCLC will receive the identified MTD/RP2D of AMG 193 + docetaxel.

Experimental: Part 1j, Phase 1: AMG 193 DSPS Substudy (US Sites Only) - Participants will receive doses of AMG 193 and comparator AMG 193 test tables at different times in a fasted state.

Experimental: Part 1k, Phase 1: AMG 193 Food Effect Substudy (US Sites Only) - Participants will receive AMG 193 once on a fasted state and once after eating a standardized high-fat, high calorie meal.

Experimental: Part 1l, Phase 1: AMG 193 Monotherapy Dose Expansion - Participants will receive the identified selected dose/MTD of AMG 193 in the following cohort: MTAP-null esophageal/gastric cancer.

Summary
Brief summary
The primary objective of Parts 1 and 2 of this study is to evaluate the safety, tolerability, and to determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of AMG 193 alone and in combination with docetaxel in adult participants with metastatic or locally advanced methylthioadenosine phosphorylase (MTAP)-null solid tumors.

The primary objective of Part 3 of this study is to evaluate the efficacy of AMG 193 in adult participants with metastatic or locally advanced MTAP-null solid tumors.
