简要总结
The purpose of the study is to assess drug-drug interaction (DDI) and safety of AZD4041 and itraconazole in healthy participants (Part 1), and to assess efficacy, safety, pharmacokinetics (PK) and pharmacodynamics (PD) of AZD404 when administered with buprenorphine/buprenorphine + naloxone in participants with moderate to severe opioid use disorder (OUD)
详细描述
This study will be conducted in 2 sequential parts.
Part 1 (Phase I) will include healthy participants and will be conducted as two separate parts. Part 1a (DDI cohort) is an open-label, fixed sequence study part which will comprise of:
-
A Screening Period from Day -28 to Day -3.
-
Three treatment periods:
-
Period 1 (Day -2 to Day 5): Participants will be admitted to the clinical unit on Day -2 and will receive a single oral dose of AZD4041 on Day 1. There will be a 5-day washout period.
-
Period 2 (Day 6 to Day 8): Participants will receive itraconazole for 3 days from Day 6 through Day 8.
-
Period 3 (Day 9 to Day 22): On Day 9, participants will receive single oral dose of AZD4041 co-administered with itraconazole. Itraconazole alone will be administered from Day 10 to Day 21.
-
A Follow-up Visit: Participants will return to the clinical unit at least 7 days and no later than 14 days after discharge.
Based on the results from Part 1a, an optional part of the study (Part 1b) may be conducted to assess the safety tolerability and PK of AZD4041 after a single oral dose. Part 1b (Single Dose Cohort) will be a randomized, placebo-controlled, double-blind (participant and investigator blinded) study part conducted in healthy participants. This study part will comprise of the following:

To assess the safety and tolerability of AZD4041 following oral administration of a single dose.
Part 1a: Area under concentration-time curve from time 0 to infinity (AUCinf) of AZD4041
时间窗: Day 1 to Day 5, Day 9 to Day 22
To assess the effect of itraconazole on the PK of a AZD4041 single oral dose.
Part 1a: Maximum observed drug concentration (Cmax) of AZD4041
时间窗: Day 1 to Day 5, Day 9 to Day 22
To assess the effect of itraconazole on the PK of a AZD4041 single oral dose.
Part 2: Change from baseline in Self-reported withdrawal symptoms measured by the Short Opioid Withdrawal Scale-Gossop (SOWS-G)

To evaluate the effects of AZD4041, as an adjunctive treatment to buprenorphine when administered after hydromorphone, on clinical measures of withdrawal in participants with OUD. SOWS-G is a 10-item psychometrically validated scale that measures participant reported withdrawal symptoms. Each of the items of the scale is scored as follows: none=0; mild=1; moderate=2; severe=3. The SOWS-G score is computed as the total sum of the item scores (giving a range for SOWS-G scores of 0 - 30). A high score indicates more severe withdrawal symptoms.
