Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cohort 1: Vibegron Adolescents (12 to < 18 years)

Part A: Participants aged 12 to \< 18 years will receive vibegron based on their weight, with dose reduction based on individual clinical condition, PK, and safety/tolerability data. Participants may be dose-reduced up to 2 times.

Part B: Participants will receive a Data and Safety Monitoring Board (DSMB)-selected vibegron dose for their weight determined from participants in their respective cohort and weight band of Part A.

Group Type EXPERIMENTAL

Vibegron

Intervention Type DRUG

Participants will be administered Vibegron orally, once daily (QD)

Cohort 2: Vibegron Children (2 to < 12 years)

Part A: Participants aged 2 to \< 12 years will receive vibegron based on their weight, after DSMB review of Cohort 1, Part A data, with dose reduction based on individual clinical condition, PK, and safety/tolerability data. Participants may be dose-reduced up to 2 times.

Part B: Participants will receive a DSMB-selected vibegron dose for their weight determined from participants in their respective cohort and weight band of Part A.
