Clinical Trial Summary

The purpose of this study is to evaluate the single-dose oral pharmacokinetics of an herbal supplement - Antitumor B - in healthy subjects.

Description:

Antitumor B (ATB), also known as Zeng Sheng Ping, is a Chinese herbal mixture composed of six plants: Sophora tonkinensis, Polygonum bistorta, Prunella vulgaris, Sonchus brachyotus, Dictamnus dasycarpus, and Dioscorea bulbifera. ATB is available as 300 mg tablets and has been traditionally used in China for dysplasia (dose 4-8 tables/ twice daily). Several studies in rodents and humans have been published demonstrating the chemopreventive activity of ATB against various cancers (e.g. lung, esophageal and oral). However, the investigators currently do not know what pharmacologically relevant concentration levels can be achieved systemically for different components of ATB in humans. Since it is a complex herbal mixture containing various key active components (KACs), relative levels of KACs in the ATB mixture can influence the bioavailability and pharmacokinetic of the individual KACs. The proposed study aim to estimate the plasma concentration of four key active components in a tablet with a chemical-defined ATB mixture. The investigators are interested in doing a human single-dose (8 tablets once) full pharmacokinetic study of ATB tablets. The investigators plan to collect 9 blood and 9 saliva samples from 8 healthy volunteers over a period of 24 hours (at pre-dose, 0.5, 1, 2, 3, 4, 6, 8, and 24 hours) to 1. determine the saliva and plasma concentration of four key constituents of ATB (matrine, dictamnine, maackiain, fraxinellone) and 2. develop the in vivo correlation between plasma and saliva concentrations

Exclusion Criteria:

1. History of active liver disease or cancer.

2. Severe current or recurrent comorbidity such as (e.g., cardiovascular, haematological, neurological, endocrine, renal, liver, GI, HIV-AIDS, or other conditions such as cancer) that could affect the absorption and/or disposition of ATB

3. Any disease/illness diagnosed by a licensed physician.

4. Blood report positive for HIV and/or Hepatitis B and C tests

5. Has had an acute illness within two weeks prior to screening.

6. Pregnant or lactating women are ineligible due to unforeseeable risks to embryo or fetus.

7. Concurrent use of any prescription medication (including medicinal botanical) except birth control pills, over the counter medication and supplements except Vitamins and mineral supplements, or herbal supplements in form of herbal mixtures, teas or individual compounds (such as querctein, curcumin, echinacea, flaxseed, ginseng, ginkgo, soy etc.) that the study PI believes could potentially impact the results/objectives of this study.
