What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether pregnenolone, a natural hormone, can safely and effectively help individuals with Alcohol Use Disorder (AUD) reduce alcohol consumption. Participants will randomly receive either pregnenolone or a placebo (a pill with no active ingredients) daily for 12 weeks, followed by a check-up a month later. The trial seeks individuals who drink alcohol at least three times a week and meet the criteria for moderate to severe AUD. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.

Will I have to stop taking my current medications?

The trial requires you to stop using certain medications like opioids, anticonvulsants, sedatives, and some steroid medications. However, stable prescribed medications for conditions like high blood pressure, heart issues, diabetes, depression, and anxiety may be allowed after review by the study physician.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that pregnenolone is generally safe for people. This treatment is a natural steroid produced by the body to help generate other hormones. It often appears in supplements, usually at lower doses than those tested in this trial.

Some studies have found that pregnenolone users might experience minor side effects, such as headaches, dizziness, or stomach issues. However, these side effects are uncommon and usually mild.

Since pregnenolone is in a Phase 2 trial for this study, it has already passed initial safety tests. This indicates it is safe enough for testing in larger groups. While this doesn't guarantee the absence of side effects, it suggests reasonable safety based on earlier research.12345

Why do researchers think this study treatment might be promising for alcoholism?

Researchers are excited about pregnenolone for treating alcoholism because it offers a fresh approach compared to standard treatments like naltrexone or acamprosate. Unlike these existing options, pregnenolone is a naturally occurring neurosteroid that may help regulate mood and stress, potentially reducing alcohol cravings. This unique mechanism of action targets the brain's stress response systems, providing a novel way to address the underlying issues of alcohol dependence. Additionally, being a natural compound, pregnenolone might offer a different side effect profile, making it an attractive option for individuals seeking alternatives to conventional medications.

What evidence suggests that pregnenolone might be an effective treatment for Alcohol Use Disorder?

This trial will compare pregnenolone with a placebo to evaluate its effectiveness for Alcohol Use Disorder (AUD). Studies have shown that pregnenolone can help reduce stress-related and alcohol-triggered cravings in people with AUD. It may also help balance the body's stress response, which is often disrupted in those with AUD. Some research suggests it might decrease heavy drinking episodes and improve overall well-being. However, other studies found no significant effect on alcohol consumption and preference. These mixed results indicate that while pregnenolone shows promise, more research is needed to fully understand its effectiveness for AUD.678910

Are You a Good Fit for This Trial?

This trial is for English-speaking adults aged 18-70 with Alcohol Use Disorder, confirmed by a positive alcohol test or reports from close contacts. Participants must consent to the study's procedures. Pregnant or nursing women, individuals not using effective birth control, opiate users, those on psychoactive drugs including anxiolytics, naltrexone or antabuse, and people with severe medical conditions or low blood pressure are excluded.

Inclusion Criteria

Subjects must meet current Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) criteria for alcohol use disorder; documented positive urine toxicology screen for alcohol at intake or collateral information from family members, significant others, room-mates etc., on recent use
Subject has voluntarily given informed consent and signed the informed consent document
Able to read English and complete study evaluations

Exclusion Criteria

Significant underlying medical conditions such as cerebral, renal, thyroid or cardiac pathology which in the opinion of study physician would preclude patient from fully cooperating or be of potential harm during the course of the study
Meet current criteria for use disorder on another psychoactive substance, such as, heroin, amphetamines, hallucinogens/Phencyclidine (PCP), excluding alcohol and nicotine
Any current use of opiates or past history of opiate use disorder (assessed via urine toxicology and self report)

Published Research Related to This Trial

The study identified two metabolites, 7 alpha-hydroxy-PREG and 7 beta-hydroxy-PREG, produced in mouse brain microsomes, with different kinetic properties indicating distinct enzymatic pathways for their production.
Different cytochrome P450 (CYP) enzymes are involved in the hydroxylation of pregnenolone, with specific inhibitors revealing that 7 alpha-hydroxylation is primarily inhibited by certain compounds, while 7 beta-hydroxylation involves CYP 1A1 and other unidentified enzymes, providing insights for future research on these metabolic processes in the brain.

In a study of post-mortem brain samples from 14 alcoholics and 10 non-alcoholic controls, significant increases in the steroid hormones DHEA and pregnenolone (PREGN) were found in alcoholics, particularly in key brain regions like the nucleus accumbens and anterior cingulate cortex.
The study also revealed a negative correlation between PREGN levels and μ-opioid receptor binding, suggesting a potential link between altered steroid hormone levels and the opioid system in the context of alcoholism.

In a study involving cynomolgus monkeys, naloxone increased pregnenolone (PREG) levels, while corticotropin-releasing factor (CRF) appeared to enhance the conversion of PREG to deoxycorticosterone (DOC), indicating a complex regulation of PREG by the HPA axis.
Dexamethasone reduced PREG levels despite increasing cortisol, and changes in PREG levels were linked to alcohol intake, suggesting that PREG responses could be a potential marker for alcohol consumption behaviors in non-human primates.
