Description of intervention(s) / exposure
Other interventions - AMG 133
Treatment: Drugs - Placebo

Experimental: Cohort A: AMG 133 - Part 1: Cohort A will consist of participants without a diagnosis of type 1 or type 2 diabetes mellitus. Participants will be randomized to receive AMG 133 or placebo in 1 of 7 dose cohorts. Participants will then have the option to begin part 2 if they meet the entry criteria. Part 2: Participants that continue into part 2 will be re-randomized to receive AMG 133 or Placebo in 1 of 4 dose cohorts.

Placebo Comparator: Cohort A: Placebo - Part 1: Cohort A will consist of participants without a diagnosis of type 1 or type 2 diabetes mellitus. Participants will be randomized to receive AMG 133 or placebo in 1 of 7 dose cohorts . Participants will then have the option to begin part 2 if they meet the entry criteria. Part 2: Participants that continue into part 2 will be re-randomized to receive AMG 133 or Placebo in 1 of 4 dose cohorts.

Experimental: Cohort B: AMG 133 - Part 1: Cohort B will consist of participants with a diagnosis of type 2 diabetes mellitus. Participants will be randomized to receive AMG 133 or placebo in 1 of 4 dose cohorts. Participants will then have the option to begin part 2 if they meet the entry criteria. Part 2: Participants that continue into part 2 will be re-randomized to receive AMG 133 or Placebo in 1 of 4 dose cohorts.

Placebo Comparator: Cohort B: Placebo - Part 1: Cohort B will consist of participants with a diagnosis of type 2 diabetes mellitus. Participants will be randomized to receive AMG 133 or placebo in 1 of 4 dose cohorts. Participants will then have the option to begin part 2 if they meet the entry criteria. Part 2: Participants that continue into part 2 will be re-randomized to receive AMG 133 or Placebo in 1 of 4 dose cohorts.


Other interventions: AMG 133
