Brief summary

Paltusotine is an oral somatostain receptor 2 (sst2) agonist being developed for the treatment of acromegaly. This single cohort, 2 period study will evaluate the relative bioavailability of two paltusotine tablet strengths in healthy volunteers. Participants will receive 1 dose of 2 x 30mg and 1 dose of 3 x 20mg of paltusotine, across 2 periods in a randomised format as follows: Period 1: 6 Participants to receive 1 dose of 2 x 30mg, 6 Participants to receive 1 dose of 3 x 20mg. Period 2: Participants to receive the other dose to what was received in Period 1. Participants will receive each dose with approximately 240ml of water, after a 10 hour overnight fast. Participants will then fast for further 4 hours after dosing. There will be 10 to 14 days between doses.

Interventions

The intervention for this study, paltusotine, is an orally bioavailable small molecule somatostatin receptor agonist that lowers growth hormone levels in acromegaly patients. Paltusotine will be supplied as 20 mg and 30 mg tablets. The study will consist of 1 cohort in which participants will receive 1 dose of 2 x 30mg and 1 dose of 3 x 20mg of paltusotine (60mg total), across 2 periods in a randomised format as follows: Period 1: 6 Participants to receive 1 dose of 2 x 30mg tablets, 6 Partic
