Phase I, Dose-Escalation Study of Dihydromyricetin (DHM) to Treat

Status Not yet recruiting

Clinical Trial Summary

The current proposal is designed as a first-in-human Phase 1 open-label, dose-escalation study to assess the safety, pharmacokinetics, and the maximum tolerated dose of DHM among healthy volunteers using a purified form of DHM from a local cGMP compliant source (Master Herbs, Inc).

Clinical Trial Description

Dihydromyricetin (DHM), a bioactive flavonoid from an edible plant (ampelopsis grossedentata), is reported to have multiple protective effects against chemical-induced liver injuries. For example, the antioxidant activity and cellular metabolic protective effects of DHM may act via the AMP kinase (AMPK) and nicotinamide adenine dinucleotide (NAD+)-dependent Sirtuin (Sirt)-1 energy regulating pathway. Furthermore, there is accumulating evidence supporting the use of DHM for the treatment of alcohol use disorder and the possible reduction/prevention of alcohol-associated liver disease in animal models. DHM may represent a novel approach to counteract alcohol-induced liver damage and promote alcohol metabolism via changes in hepatocellular bioenergetics and mitochondrial biogenesis driven by the AMPK/Sirt-1/PGC-1α axis. These preclinical data suggest the potential of DHM as a novel therapeutic agent in alcohol-related diseases. However, further study in humans is warranted. While DHM has been used for herbal tea in traditional Chinese medicine for hundreds of years, and there has been a small clinical trial using DHM in China among individuals with non-alcoholic fatty liver disease, there have been no controlled human studies published that have assessed the safety, pharmacokinetics, or optimal dosing of DHM in humans. DHM is marketed as a dietary supplement in the United States and is not regulated by the Food and Drug Administration (FDA) as a drug. Because the FDA has little control over the quality of herbal products such as DHM, it is necessary to quantitatively estimate the potentially active ingredients and the pharmacokinetic (PK) profile with oral administration. The current proposal is designed as a first-in-human Phase 1 open-label, dose-escalation study to assess the safety, pharmacokinetics, and the maximum tolerated dose of DHM among healthy volunteers using a purified form of DHM from a local cGMP compliant source (Master Herbs, Inc). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
