Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug Sunobinop for treating alcoholism?

The research does not provide direct evidence about Sunobinop, but it mentions that positive allosteric modulators (PAMs) of the GABAB receptor, like COR659, have been effective in reducing alcohol consumption in animal studies. This suggests that similar drugs might help in treating alcohol use disorder. ^{1 2 3 4 5}

How does the drug Sunobinop differ from other treatments for alcoholism?

Sunobinop is unique because it may involve the GABAB receptor system, similar to other treatments like saikosaponin A, which has shown potential in reducing alcohol self-administration in animal studies. This suggests that Sunobinop might work by modulating the brain's response to alcohol, potentially offering a new approach to treating alcoholism. ^{1 6 7 8 9}

What is the purpose of this trial?

The purpose of this study is to evaluate the efficacy of sunobinop compared to placebo on alcohol consumption in subjects with alcohol use disorder.

Findings from Research

COR659, a novel positive allosteric modulator of the GABAB receptor, effectively suppressed binge-like drinking in rodents, indicating its potential as a treatment for alcohol misuse.

In experiments with C57BL/6J mice and Sardinian alcohol-preferring rats, non-sedative doses of COR659 significantly reduced alcohol intake during binge-drinking scenarios, suggesting its efficacy without causing sedation.

The selective V1b receptor antagonist SSR149415 significantly reduced alcohol intake and preference in mice, indicating its potential as a treatment for alcohol dependency.

Combining SSR149415 with the mu-opioid receptor antagonist naltrexone at lower doses resulted in a greater reduction in alcohol consumption than either drug alone, suggesting a synergistic effect that could lead to effective treatment with fewer side effects.

The FDA has approved three main drugs for treating alcoholism: disulfiram, naltrexone, and acamprosate, which are specifically designed to help individuals with alcohol dependence.

There is ongoing research into other medications, such as nalmafene, topiramate, and ondansetron, which are being used off-label, indicating a potential for new treatment options as our understanding of alcoholism improves.

In a systematic review of 8 studies involving 1082 alcohol-dependent patients, sodium oxybate (SMO) was found to be more effective in high-severity patients, showing a significant increase in abstinence rates and percentage of days abstinent compared to mild-severity patients.

Longer treatment durations also enhanced the efficacy of SMO, with each additional month leading to a notable increase in the percentage of days abstinent, particularly in high-severity populations.

In a large randomized controlled trial involving 314 alcohol-dependent patients, sodium oxybate (SMO) significantly increased the cumulative abstinence duration (CAD) by an average of 43.1 days compared to placebo during the 6-month treatment period.

The positive effects of SMO on maintaining abstinence were sustained even after the medication was discontinued, and the treatment was well-tolerated by participants.

Saikosaponin A (SSA), derived from the herb Bupleurum falcatum, significantly reduces alcohol self-administration in selectively bred Sardinian alcohol-preferring rats, indicating its potential as a treatment for alcohol use disorders.

The study suggests that the GABAB receptor system plays a crucial role in SSA's ability to suppress alcohol consumption, as evidenced by the partial blockade of SSA's effects when a GABAB receptor antagonist was used.

COR659, a new positive allosteric modulator of the GABAB receptor, effectively reduced alcohol self-administration in rats at non-sedative doses, demonstrating greater potency than the reference GABAB PAM, GS39783.

The reduction in alcohol self-administration appears to be primarily due to its action on the GABAB receptor, while also involving other receptor systems, such as the cannabinoid CB1 receptor, particularly in the context of seeking and consuming highly palatable foods.

Baclofen and GS39783 effectively suppressed alcohol self-administration in selectively bred alcohol-preferring rats, with baclofen showing a stronger effect across different rat lines, indicating its potential as a treatment for alcohol use disorders.

The study revealed that the sensitivity to these treatments varies among different rat lines, which may reflect the varying effectiveness of alcohol pharmacotherapies in different types of human alcoholics.

The novel GABAB-positive allosteric modulator ASP8062 significantly reduced alcohol self-administration in male and female rats, showing promise as a treatment for alcohol use disorder (AUD) without the side effects associated with baclofen.

While both ASP8062 and baclofen decreased alcohol consumption, ASP8062 did not affect locomotor activity, indicating it may have a safer profile compared to baclofen, which had varying effects on activity based on sex.
