What is the purpose of this trial?

This trial explores the safe dosage of a substance called harmine. Researchers are testing harmine in various doses to determine the highest amount that does not cause serious side effects. Eligible participants should be healthy, aged 18 to 55, with a BMI (a measure of body fat based on height and weight) between 19 and 30. The study excludes individuals with major health issues or those taking certain medications that affect the brain or heart. Participants will take harmine in the form of Harmine Hydrochloride Capsules. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

Yes, you will need to stop taking certain medications. The trial does not allow medications that affect the central nervous system or cardiovascular system, as well as some over-the-counter drugs and herbal remedies. It's best to discuss your current medications with the trial team to see if they are allowed.

Is there any evidence suggesting that harmine is likely to be safe for humans?

Research shows that harmine hydrochloride is still under investigation for safety in humans. Clear information from past studies about its tolerability remains unavailable. This trial is in the early stages, known as Phase 1, where scientists begin assessing harmine's safety. Researchers aim to find the right dose that people can handle without excessive side effects. Participants might experience some reactions as scientists determine the safest way to use harmine. Since it's in Phase 1, limited safety data is available for humans so far. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about harmine because it offers a novel approach to treatment with its unique mechanism of action. Unlike many standard treatments that target symptoms directly, harmine works by interacting with specific pathways in the brain that may influence mood and cognition. This could potentially lead to faster and more effective outcomes for conditions related to these pathways. Additionally, harmine's active ingredient is derived from natural sources, offering a fresh alternative to synthetic pharmaceuticals.

What evidence suggests that harmine might be an effective treatment?

Research shows that harmine has potential benefits in several areas. Studies have found that harmine can slow cancer cell growth and prevent their spread by blocking the process that allows cancer cells to change and move. Other research suggests that harmine can reduce heart muscle enlargement, potentially aiding heart problems. While these findings are promising, they primarily come from lab and animal studies. More research is needed to understand harmine's effectiveness in humans. Participants in this trial will receive one of seven possible doses of harmine to further investigate its effects. ^{6 7 8 9 10}

Published Research Related to This Trial

The safety of marketed drugs is a significant concern, as some commonly prescribed medications can lead to serious or life-threatening side effects in patients.

The ChEMBL resource will provide a curated drug safety data set, including toxicity classifications and black box warnings, which will be freely available and regularly updated to aid in drug safety research and discovery.

An international study found that 70% of adverse drug events in humans were predicted by animal studies, indicating a good correlation between animal and human toxicity assessments.

While animal studies effectively identified many toxic effects, certain severe adverse events, like immuno-allergies, were not detected, highlighting the need for improved predictive tools in drug safety evaluations.

Between 2010 and 2016, 164 safety advisories regarding cardiac-related adverse events were issued by regulators in Australia, Canada, the UK, and the US, highlighting the prevalence of risks associated with 61 different drugs, primarily involving cardiac arrhythmias and coronary artery disorders.

While monitoring patients was the most common recommendation in these advisories, only 41.2% provided detailed guidance on how to conduct this monitoring, indicating a need for more consistent and comprehensive information for healthcare professionals and consumers regarding rare but serious medication harms.
