Evolution of Practice of Medicine • Before 18th Century : • Traditional Medicine is the only form of Medicine in the East.Survival and Quality of Life dependent on Traditional Medicine Traditional Medicine Integrated Modern Medicine Increasing popularity of T/CM Medicine • 19th Century • Influx of Modern Medicine • -noted for its ease and effectiveness • 21st Century • Efforts towards • Integration of • Modern and T/CM Modern Medicine 20th century
What should be the objective of R&D in Traditional Medicine? 1. Integration of proven safe and efficacious Traditional medicine practice and products into the healthcare system of the country, as envisaged by WHO in 1978 Alma-Ata Declaration 2. Practitioners of traditional medicine should be qualified and adhere to professional ethics in their practice 3. The practice and the products used should be proven safe and effective

The drug development process from the preclinical testing stage to approval takes an average of 15 years
Good Clinical Practice • High ethical and scientific standard • Integrity of data • Safety • Protect rights of study subjects
Why bother with GCP?…some standard responses • What is that? • I’m far too busy to be bothered with that! • What’s wrong with the way things are now? • After all, Traditional medicines have been used extensively over generations by our forefathers without complications • How do you do it? • How much will it cost?
Why GCP • As physicians and healthcare practitioners, we want only safe and effective treatments for our patients • Adhering to GCP is the best way to ensure this in a clinical trial • Adhering to GCP is in our patients best interest

If you want to be an investigator…… • You must make time to do the study • You must be interested in the scientific aspects of the trial and not the finance aspects • You must be sure that you can meet the recruitment targets • You should not have competing trials • You must be aware of and adhere strictly to the investigator’s GCP responsibilities
Time • Time to identify subjects • Time with the sponsor and trial monitor • Attending investigator meetings • Time with the subject • Time for audits and inspection
Does the centre have adequate facilities • Clinical trials team effort • Principle investigator (Physician) • Co investigator (TM practitioner) • Study coordinator (Nurse) • Pharmacist
Investigator’s ResponsibilitiesPre-Study • Ensure adequate time, facilities, staff • Obtain IRB/Ethics Committee approval of the protocol, amendments, informed consent document and any advertisements • Investigational drug brochure
Investigator’s ResponsibilitiesDuring Study • Ensure that the study is conducted according to the protocol and ICH/regulatory agency standards, randomization procedures • Obtain written informed consent of each subject to whom the drug is administered prior to entering the study
Investigator’s ResponsibilitiesDuring Study (cont’d) • Prepare and maintain accurate and complete records • Case records • Progress, final reports • Safety reporting • Maintain Drug Accountability
Investigator’s ResponsibilitiesDuring Study (cont’d) • Implement a system of drug disposition, including: • Dates • Quantity • Use by Subjects
Helpful Hints Proven methods to improve GCP compliance and save your time
Follow the Protocol • make sure all site staff understand completely • adhere to Inclusion / Exclusion Criteria • be aware of "interfering medications" • may confound data interpretation, invalidate results
Documentation Review To establish that: • Research was conducted under proper authority • Patients' rights and safety were protected • Study can be reconstructed • Data supports conclusions
Data supports conclusions... Source documents • exist • are readily available • accurately support data reported • tell the whole story
Demonstrate Involvement in the Study • Documentation of: • Physical Exams • Patient Histories • Adverse Events • Abnormal Lab Results • Be Able to Describe Unusual Events • Early Discontinuations • Serious Adverse Events • Protocol Violations
Documentation • “If it is not written, • IT DID NOT HAPPEN !” • Document what happened as well as what did not happen
