About this study

Official title: A Phase 1, Double-blind, Placebo-controlled, Single-ascending Dose, Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics Study of DCR-AUD in Healthy Volunteers

DCR-AUD will be evaluated for safety, tolerability, pharmacokinetics, and pharmacodynamics in healthy volunteers.

Read the detailed description

DCR-AUD is being developed for the treatment of alcohol use disorder (AUD) in adults using an RNA interference (RNAi) technology platform. This is a 24-week, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, PK, and PD of single-ascending doses (SAD) of DCR-AUD administered to adult HVs. The single doses of DCR-AUD will be administered to adult HVs across 4 sequential cohorts (3 planned [80 mg, 240 mg, 480 mg] and one optional [960 mg]). Each cohort will comprise a sentinel group of 3 participants (2 active, 1 placebo) and an expanded group of 6 participants (4 active, 2 placebo). The sentinel group will be followed for the assessment of safety and tolerability and characterization of PK but who will not undergo any EIAs. Participants will receive a single dose of study intervention on Day 1 and will be followed for 24 weeks. Participants who have positive ethanol reaction symptoms at the Day 169 EIA (e.g., nausea, vomiting, or substantial flushing) will return every 28 (±7) days for follow-up EIAs until the positive ethanol reaction symptoms abate. These conditional follow-up (CFU) EIAs will not require overnight admission to the clinic, but all other aspects of the EIA will be conducted (see Table 3). Participants will be observed for not less than 6 hours after ethanol administration and will not be discharged until the Investigator deems it medically safe to do so.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

    An Adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study intervention. A TEAE is defined as an AE that begins or that worsens in severity after the study drug has been administered. An SAE is defined as any untoward medical occurrence that at any dose: results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, leads to a congenital anomaly /birth defect, is the other important medical event.

    Measured: From Day 1 up to 24 Weeks

  2. Number of Participants With Severity Grades of TEAEs

    An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A TEAE is defined as an AE that begins or that worsens in severity after the study drug has been administered. As per the Common Terminology Criteria for Adverse Events (CTCAE), version 5.0, Grade 1: mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; treatment not indicated; Grade 2: moderate; minimal, local, or noninvasive treatment indicated; limiting age-appropriate activities of daily living; Grade 3: severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care activities of daily living; Grade 4: life-threatening consequences; urgent treatment indicated; Grade 5: fatal.

    Measured: From Day 1 up to 24 Weeks

  3. Number of Participants With Dose-limiting Toxicities (DLTs) as Assessed by Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0

    DLT is defined as an AE of greater than or equal to (>=) Grade 3 intensity (CTCAE Version 5.0) in one participant, unless it is clearly the result of a non-study-related event OR any 2 AEs of >= Grade 2 intensity in the same body system in one participant.

    Measured: From Day 1 up to 24 Weeks

    Measured: From Baseline (Day -1) up to 24 weeks

  6. Number of Participants With Change From Baseline in Clinically Significant Abnormal Laboratory Values

    Number of participants with change from baseline in clinically significant abnormal laboratory values (hematology, clinical chemistry, coagulation and routine urinalysis parameters) is presented.

    Measured: From Baseline (Day -1) up to 24 weeks

  7. Number of Participants With Change From Baseline in Clinically Significant Physical Examination Findings

  7. Six Symptom Responses During Ethanol Interactions Assessments (EIAs)

    The degree of aldehyde dehydrogenase 2 (ALDH2) reduction was measured by quantitative assessment of 6 symptom (flushing, headache, palpitations, light-headedness, nausea, and vomiting) responses during EIAs. Each of 6 symptoms was assessed at each of the 4 time points during each EIA. Composite score at each time point was the sum of severity ratings for each of the 6 symptoms. Peak composite score (of the 3 post-alcohol initiation composite scores at each EIA test) was used as the subject's peak score for that EIA test. The point system was as follows: 0 point = symptom not present, 1 point = mild severity of symptom, 2 points = moderate severity of symptom and 3 points = severe severity of symptom. Participants were given a composite score, which was the sum of the scores of all 6 symptoms (highest possible score is 18).

    Measured: Day -1, Day 4, Day 15, Day 29, Day 57, Day 85, Day 113 and Day 169

  8. Cmax: Maximum Observed Plasma Concentration of Acetaldehyde

    Measured: Baseline (Day -1), Day 169

  11. Change From Baseline in Facial Skin Temperature

    Change in facial skin temperature was measured to evaluate the PD effects of ALDH2 reduction by DCR-AUD during serial EIAs for the expanded group. Facial skin temperature was measured using a surface scanning thermometer.

    Measured: Baseline (Day -1), Day 169

  12. Change From Baseline in Subjective Effects of Alcohol Scale (SEAS) Score

    Subjective feelings of alcohol intoxication or intolerance is measured to evaluate the PD effects of ALDH2 reduction by DCR-AUD during serial EIAs. Participants' subjective experience of the effects of alcohol was assessed using the SEAS. The SEAS is a 14-item tool that allows participants to rate the subjective effects of alcohol. Participants rated the extent to which they were feeling (high/low arousal positive: relaxed, wobbly, lively, secure, woozy, fun, calm, dizzy, mellow, funny, talkative and high/low arousal negative: demanding, rude and aggressive) on an 11-point scale from (0 = not at all, 10 = extremely). higher values represent more effects.
