Pharmacokinetics Study of Antitumor B in Healthy Volunteers

2020-01-22 12:12:55 | BioPortfolio

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, we 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. We are interested in doing a human single-dose (8 tablets once) full pharmacokinetic study of ATB tablets. We plan to collect 9 blood and 9 saliva samples from 8 healthy volunteers over a period of 24 hrs (at pre-dose, 0.5, 1, 2, 3, 4, 6, 8, and 24 hrs) 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

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.

Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.

Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.

Simple rapid heartbeats caused by rapid discharge of impulses from the SINOATRIAL NODE, usually between 100 and 180 beats/min in adults. It is characterized by a gradual onset and termination. Sinus tachycardia is common in infants, young children, and adults during strenuous physical activities.
