4. Carefully conducted clinical trials are performed in human
volunteers to provide answers to questions such as:
.
Does a
treatment work?
Does it work
better than
other
treatments?
Does it have
side effects?

5. Clinical research is often conducted at academic
medical centers and affiliated research study
sites.

6. 2. PARTICIPATION IN A CLINICAL
TRIAL
Inclusion and exclusion
criteria factors:
Age
Gender
The type and stage of a
disease
Previous treatment history
& medical condition.

8. Clinical trials help to
develop new and better
treatments for patients.
Assessing efficacy and
safety of a new
treatment.
For this reason, new
treatments usually take
a lot of time before
becoming publicly
available.

9. Study design :
•Randomized trial / non randomized
•Blinding
•Placebo controlled study
•Crossover designs
•Factorial designs
•Study population
( inclusion/exclusion criteria)
•Planned statistical analyses/data need
•Enrollment of subjects
•Interventions
•Follow up of subjects
•Data collection, data monitoring etc.

14. Phase 0
• Also called Human Micro-dosing studies.
• Gathers preliminary data Pharmacodynamics
and Pharmacokinetics.
• Gives no data on safety or efficacy.
• Small number of subjects (10-15).
14
15. Phase I
• First stage of testing in human subjects (20-
100).
• Designed to assess the safety, tolerability, PK
and PD of drug.
• Dose ranging – Dose escalation.
• Kinds of Phase I
– SAD
– MAD
– Food effect
15
16. Phase II
• Therapeutic Exploratory Trial. (100-300 Subjects).
• Efficacy in patients (primary objective)
• Safety issues (secondary objective)
• Optimum dose finding
• Phase II
– Phase IIA: Designed to assess dosing
requirements
– Phases IIB: Designed to study efficacy
16
17. Phase III
• Therapeutic confirmatory trials. (300-3000 subjects).
• To establish efficacy of the drug against existing
therapy in larger number of patients, method of usage
etc.
• Subtypes
– Phase IIIA: To get sufficient and significant data.
– Phase IIIB: Allows patients to continue the
treatment, Label expansion, additional safety data.
17
18. Phase IV
• Post Marketing Studies (PMS).
• Involves safety surveillance.
• Determine behavior of drug in real life
situations.
• Evaluate action of drug in a situation of
missed dosage or over dosage.

28. Clinical Trial Quotations
“India is an emerging market with growing number of entrepreneurs foraying into
research and healthcare. Indian government is creating an effective regulatory
framework. Protection of patents and IPR is now improving. India has a better
place than countries like China in the clinical trials field”, Dr Charles Pierce,
president Global Clinical Partners, Inc. USA, said
