Description of intervention(s) / exposure
Treatment: Drugs - AMG 224

Experimental: Dose Exploration: AMG 224 Dose A - Participants were administered AMG 224 Dose A as an intravenous (IV) infusion once every 3 weeks (Q3W) on Day 1 of each cycle, where each cycle is 3 weeks.

Experimental: Dose Exploration: AMG 224 Dose B - Participants were administered AMG 224 Dose B as an IV infusion Q3W on Day 1 of each cycle, where each cycle is 3 weeks.

Experimental: Dose Exploration: AMG 224 Dose C - Participants were administered AMG 224 Dose C as an IV infusion Q3W on Day 1 of each cycle, where each cycle is 3 weeks.

Experimental: Dose Exploration: AMG 224 Dose D - Participants were administered AMG 224 Dose D as an IV infusion Q3W on Day 1 of each cycle, where each cycle is 3 weeks.

Experimental: Dose Exploration: AMG 224 Dose E - Participants were administered AMG 224 Dose E as an IV infusion Q3W on Day 1 of each cycle, where each cycle is 3 weeks.

Experimental: Dose Exploration: AMG 224 Dose F - Participants were administered AMG 224 Dose F as an IV infusion Q3W on Day 1 of each cycle, where each cycle is 3 weeks.

Experimental: Dose Exploration: AMG 224 Dose G - Participants were administered AMG 224 Dose G as an IV infusion Q3W on Day 1 of each cycle, where each cycle is 3 weeks.

Experimental: Dose Expansion: AMG 224 Dose H + prior CD38 targeting antibody treatment - Participants who had prior treatment with CD38-targeting antibody were administered AMG 224 Dose H (the maximum tolerated dose [MTD] based on the dose exploration phase) as an IV infusion Q3W on Day 1 of each cycle, where each cycle is 3 weeks.

Experimental: Dose Expansion: AMG 224 Dose H + no prior CD38 targeting antibody treatment - Participants who had no prior treatment with CD38-targeting antibody were administered AMG 224 Dose H (the MTD based on the dose exploration phase) as an IV infusion Q3W on Day 1 of each cycle, where each cycle is 3 weeks.
