Study type: INTERVENTIONAL
Overall status: COMPLETED
Phase: PHASE1
Conditions: Opioid Use Disorder (OUD)

First posted: 2022-02-10
Enrollment: 36
Sex: ALL
Minimum age (years): 18
Maximum age (years): 55
Standard ages: ADULT
Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: For each cohort, 9 participants will be randomly assigned to receive AZD4041 and 3 participants will be assigned to receive placebo. Within each cohort, 2 participants will be randomized initially to AZD4041 or placebo (1:1 ratio) to allow a sentinel dosing approach. Providing no clinically significant issues have been noted after the first 3 doses of the initial 2 (sentinel) participants in a cohort and provided the Day 3 safety laboratory tests for the 2 participants have been reviewed, the remaining 10 participants will be randomized to AZD4041 or placebo in an 8:2 ratio. All participants will receive either AZD4041 or placebo administered once daily for 14 days.
Primary purpose: TREATMENT

Brief summary: This is a Phase 1, single-centre, randomized, double-blind, placebo-controlled, multiple ascending doses (MAD) study in healthy male and female adult participants.

The study will include up to 48 participants (12 participants per cohort) who will be randomized 9:3 to active drug or placebo. Each cohort will receive AZD4041 or placebo in a MAD study.

A sequential cohort MAD design will be employed to assure that higher doses are administered to healthy participants only after lower doses have demonstrated an acceptable safety profile.

The total study duration will be up to 59 days (including Screening) per participant.
