First-in-Human Study of SRT-015 in Healthy Subjects.

Syneos Health81 enrolled

Overview

This is phase 1 first-in-human trial evaluating SRT-015 to assess safety, tolerability and pharmacokinetics. This study will be conducted in 3 parts - SAD, MAD and Food Effect with target of 96 healthy volunteers. This will be a single center, Phase 1, randomized, double-blind, placebo controlled, SAD and MAD study of dose escalation cohorts evaluating administration of SRT-015 or placebo. Additionally, PK will be assessed in fed and fasting states.

The study will be divided into three parts: Part A: SAD- Randomized, double-blind, placebo-controlled single oral escalating dose of SRT-015 or placebo in five cohorts (A1-A5). Each cohort will include 8 healthy subjects (6 randomized to receive SRT-015 and 2 to receive placebo). Two subjects from each cohort (1 to receive SRT-015 and 1 to receive placebo) will be dosed as sentinels, with the remainder of the subjects of each cohort (5 to receive SRT-015 and 1 to receive placebo) dosed at least the following day. An extension cohort (Cohort A6) will allow investigation of a repeat or intermediate dose, at the discretion of the Sponsor or Safety Review Committee (SRC). Part B: MAD- Randomized, double-blind, placebo-controlled multiple oral escalating dose of SRT-015 or placebo in four cohorts (B1-B4). Each cohort will include 8 healthy subjects (6 randomized to receive SRT-015 and 2 to receive placebo). Subjects will be treated with SRT-015 or placebo for 7 days. An extension cohort (Cohort B5) will allow investigation of a repeat or intermediate dose at the discretion of Sponsor and SRC. Part C: Food Effect (FE)- Randomized, crossover oral SRT-015 dose study of 8 healthy adults divided into two concurrent groups where half (n=4) of the subjects (Cohort C1) will receive the first dose as an oral suspension in fasting state on Day 1 of Period 1, the second dose as capsule formulation in fasting state on Day 1 of Period 2 and the third dose as a capsule formulation in a fed state on Day 1 of Period 3. The remainder (n=4) of the subjects (Cohort C2) will receive the first dose as an oral suspension in fasting state on Day 1 of Period 1, the second dose as a capsule formulation in a fed state on Day 1 of Period 2 and the third dose as a capsule formulation in a fasting state on Day 1 of Period 3.

Interventions

SRT-015DRUG

Each study part (A,B and C) will be completed sequentially, but with partial overlapping. The first cohort of Part B (Cohort B1) may be initiated after safety, tolerability and available PK data are assessed and deemed suitable to continue for a single dose on Part A that is equal to or greater than the total exposure of cohort B1. Part C (Cohort C1 \& C2) may be initiated after safety, tolerability and PK data are assessed and deemed suitable to continue for a single dose in part A that is at least double the specified dose from part C.
