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.

Day -1 (baseline), Day 14, Day 28, Day 42, Day 56, Day 70, Day 84, Day 112, Day 140 and Day 168
AUC0-last: Area Under the Plasma Concentration Curve From Time Zero to the Last Quantifiable Concentration of DCR-AUD

Frequently asked questions about DCR-AUD

What is DCR-AUD used for?

DCR-AUD is an investigational small molecule being developed for Alcohol Use Disorder (AUD). It is currently in Phase 1 clinical development and is not yet approved by the FDA. The drug is being studied in healthy volunteers to evaluate its safety and tolerability.

Who makes DCR-AUD?

DCR-AUD is being developed by Novo Nordisk A/S, a pharmaceutical company listed on the stock exchange under the ticker NVO. The company is conducting clinical trials for this investigational drug in the United States.

What phase is DCR-AUD in?

DCR-AUD is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Two Phase 1 trials have been completed, both involving healthy volunteers, to assess the drug's safety and pharmacokinetics.

What clinical trials is DCR-AUD in?

DCR-AUD has been studied in two completed Phase 1 clinical trials. The first trial, NCT05021640, enrolled 36 healthy volunteers in the United States. The second trial, NCT05845398, enrolled 16 healthy volunteers. Both trials were randomized, double-blind, and placebo-controlled.

How does DCR-AUD work?

DCR-AUD is a small molecule being developed for Alcohol Use Disorder. The specific molecular target of DCR-AUD has not been disclosed in available information, so its mechanism of action is not publicly detailed.

Is DCR-AUD the same as any other drug?

DCR-AUD is not known to have any alternative names. It is a distinct investigational drug being developed by Novo Nordisk for Alcohol Use Disorder, and no other names have been associated with it in clinical trial records.
