Study Endpoints

Primary Endpoints

Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
From Day 1 up to 24 Weeks

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.

Number of Participants With Severity Grades of TEAEs
From Day 1 up to 24 Weeks

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 lifethreatening; 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.

Number of Participants With Change From Baseline in Clinically Significant Abnormal Vital Signs
From Baseline (Day -1) up to 24 weeks

Number of participants with change from baseline in clinically significant abnormal vital signs (temperature, pulse rate, respiratory rate, and blood pressure) is presented.

Number of Participants With Change From Baseline in Clinically Significant Abnormal Electrocardiogram (ECG)
From Baseline (Day -1) up to 24 weeks

Number of participants with change from baseline in clinically significant abnormal ECG findings (Heart rate, PR interval, QRS interval, QT interval and QT interval using Fridericia's correction \[QTcF\]) is presented.

Number of Participants With Change From Baseline in Clinically Significant Abnormal Laboratory Values
From Baseline (Day -1) up to 24 weeks

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

Number of Participants With Change From Baseline in Clinically Significant Physical Examination Findings
From Baseline (Day -1) up to 24 weeks

Number of participants with change from baseline in clinically significant physical examination findings (assessments of the cardiovascular, respiratory, gastrointestinal, neurological, and skin systems and inspection of the injection site) is presented.

Number of Participants With Dose-limiting Toxicities (DLTs) as Assessed by Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0
From Day 1 up to 24 Weeks

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.

Number of Participants With Change From Baseline in Clinically Significant Abnormal Electrocardiogram (ECG) Findings
From Baseline (Day -1) up to 24 weeks

Number of participants with change from baseline in clinically significant abnormal ECG findings (Heart rate, PR interval, QRS interval, QT interval and QT interval using Fridericia's correction \[QTcF\]) is presented.

Frequently asked questions about DCR-AUD

What is DCR-AUD?

DCR-AUD is an investigational small molecule being developed by Novo Nordisk A/S for the treatment of alcohol use disorder. It is in Phase 1 clinical development. Both of its completed Phase 1 trials enrolled healthy volunteers rather than patients with alcohol use disorder, and no regulatory approval has been granted.

Who makes DCR-AUD?

DCR-AUD is being developed by Novo Nordisk A/S, which trades under the ticker NVO. Novo Nordisk is the sponsor of the two Phase 1 trials of DCR-AUD conducted in the United States. The program sits within the psychiatry therapeutic area, targeting alcohol use disorder.

What phase is DCR-AUD in?

DCR-AUD is in Phase 1 development. Two Phase 1 trials have been completed, and no trials are currently active. Both studies were randomized, double-blind, and placebo-controlled, and together they enrolled 52 healthy volunteers aged 21 years and older in the United States.

What clinical trials is DCR-AUD in?

DCR-AUD has been studied in two completed Phase 1 trials. NCT05021640 was a Phase 1 study in healthy volunteers that enrolled 36 participants. NCT05845398 was a Phase 1b study in healthy volunteers that enrolled 16 participants. Both were conducted in the United States and both have completed.

What is DCR-AUD used for in alcohol use disorder?

DCR-AUD is being developed as a treatment for alcohol use disorder. It is an investigational small molecule and has not been approved for any indication. The completed Phase 1 trials enrolled healthy volunteers rather than individuals diagnosed with alcohol use disorder, so the program remains in early clinical development.

Are the DCR-AUD trials placebo-controlled?

Yes. Both completed Phase 1 trials of DCR-AUD were randomized, double-blind, and placebo-controlled. NCT05021640 enrolled 36 healthy volunteers and NCT05845398, a Phase 1b study, enrolled 16 healthy volunteers. All participants were 21 years of age or older, and both studies were run in the United States.
