Study Description

Brief Summary

Background:

Alcohol use disorder (AUD) affects about 29.5 million people in the United States. Only 3 medicines have been approved by Food and Drug Administration to treat AUD. Researchers want to find better treatments for AUD. Animal studies found that a medicine called spironolactone, may decrease the amount of alcohol the animals drank. Spironolactone is approved to treat high blood pressure, or heart failure in people. It is not approved to treat AUD.

Objective:

To test a medicine (spironolactone) in people who sometimes drink excessive alcohol in order to understand how the body breaks down spironolactone and if there are any side effects in people who drink alcohol while taking this medicine.

Eligibility:

People aged 21 and older with AUD.

Design:

Participants will have 4 separate 7-day stays at a clinic in Baltimore over 2 months. Spironolactone is a capsule you swallow. Participants will take a capsule twice a day for 5 days during each clinic stay. During 1 of their 4 stays, they will take a placebo instead of the medicine. The placebo capsule looks just like the spironolactone capsule but contains no medicine. Participants will not know when they are taking the medicine or the placebo.

Participants will not drink alcohol until day 6 of each clinic stay. Then they will be asked to drink alcohol in a bar-like area in the clinic. Their breath and blood alcohol levels and their well-being will be measured.

Participants will undergo other tests in the clinic:

A DEXA (dual energy X-ray absorptiometry) scan uses X-rays to measure bone density and muscle mass. Participants will lie on an open-top, padded table, then a small arm will scan the full length of their body. The radiation participants will get in this study is about the same as from one regular x-ray.

Blood tests. Participants may feel some discomfort at the site of needle entry.

Electrocardiogram. This test records the heart activity. Sensors are attached to the skin with stickers and removed after a few minutes.

Urine tests. All urine will be collected over a 3-day period during each stay. We will measure the amount of urine, and different hormones and salts in the urine.

Questionnaires and tasks. Participants will answer questions about their alcohol use. They will perform tasks to test mood, craving, mental and physical coordination, and how much they feel an effect from alcohol after drinking.

Detailed Description

Study Description:

This study will examine pharmacokinetic (PK) and pharmacodynamic (PD) parameters of spironolactone and alcohol, during concomitant oral administration (0, 100, 200, 400 mg/day spironolactone PO), and test the safety and tolerability of spironolactone, co-administered with alcohol, in individuals with alcohol use disorder (AUD).

Objectives:

Our objective is to assess PK and PD parameters during spironolactone-alcohol co-administration, in individuals with AUD. We will also test the safety, tolerability, and potential drug-alcohol interaction.

Endpoints:

Primary endpoint:

Spironolactone and alcohol PK during concomitant administration (0, 100, 200, and 400 mg/day spironolactone).

Secondary endpoints:

Assessment of subjective and cognitive effects of acute alcohol administration during concomitant spironolactone treatment (0, 100, 200, and 400 mg/day).
Number and severity of adverse events (AEs) experienced, compared between placebo (0 mg/day) and all three spironolactone doses (100, 200, 400 mg/day).
PK characteristic of spironolactone active metabolites, canrenone, 7-alpha-thiomethylspirolactone (TMS) and 6beta- hydroxy-7alpha-thiomethylspirolactone (HTMS), before and after administration of alcohol.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: 1 Participants will receive oral placebo and/or spironolactone	Drug: Spironolactone Spironolactone and its matched placebo will be encapsulated into hard gelatin capsules, in same color, size and taste, to allow blinding. Participants will receive 2x50 mg/day, 2x100 mg, and 2x200 mg/day in three sessions (Visits); these Visits always occur in ascending order of dosage. In the remaining session, participants receive the placebo. Spironolactone is approved by the FDA, commercially available, and used in clinical practice for the treatment of hypertension, NYHA Class III-IV heart failure, edema in cirrhotic patients, and primary hyperaldosteronism. Comprehensive information about spironolactone, including its pharmacological properties, are provided in the Prescribing Information.
Placebo Comparator: 2 Participants will receive oral placebo and/or spironolactone	Drug: Placebo Placebo
