Overview of the Clinical Trial & Protocol

Jane Fendl

March 31, 2010

Version: Final 31- Mar-2010

phases of the clinical trial
Phases of the Clinical Trial

Phase 1 – “human pharmacology trials”

  • First time tested in man
  • Healthy normal volunteers
  • To gather information about the drug’s safety and the effect of the drug on the human body
  • Pharmacokinetic evaluation – how the drug is absorbed the way it is absorbed, distributed in the body, metabolized and excreted
  • Dose is progressively increased until a tolerable toxicity level is achieved
  • Measures AEs
  • Determine maximum tolerable dose

21 CFR 312.21

Version: Final 31- Mar-2010


Phase 2 – “therapeutic exploratory trials”

  • Volunteers with targeted disease state
  • Testing for safety and efficacy
  • To determine the potential effectiveness
  • Identify common adverse events
  • Ensure the drug has suitable risk to benefit ratio
  • To determine the optimal effective dose
  • To prove efficacy by evaluating an objective or comparative measurement such as:
    • Positive change in the disease process
    • Improvement in quality of life
    • Reduction in mortality
    • Improvement in symptomatology

21 CFR 312.21

Version: Final 31- Mar-2010


Phase 3a – “therapeutic confirmatory trials”

To evaluate safety and efficacy in a large number of


Emphasis on assessing the tolerance to the drug

Additional gathering of information about drug

interactions and addiction potential

Potential effectiveness of the product

Identify common adverse events within a

heterogeneous population

Expanded number of subjects with specific problem

or indication

21 CFR 312.21

Version: Final 31- Mar-2010


Phase 3b – “therapeutic use trials”

  • Further safety and efficacy as well as new indications
  • More subjects
  • Longer period of time
  • Tested for long-term effects
  • Understand how the product is prescribed
  • May include thousands of subjects
  • Subjects with different stratifying characteristics
  • such as age, race & concomitant medications
  • Gather information such as:
    • Response to product
    • Safety in general population
    • Safety for subjects with certain characteristics
    • Safety in association with other drug
    • Affect on Subject’s quality of life
    • 21 CFR 312.21

Version: Final 31- Mar-2010


Phase 4 – “post-marketing trials”

  • May be at the request of regulatory authorities as
  • a condition of approval
  • Sponsor may wish to compare the drug with other
  • active agents for:
    • Marketing reasons
    • Cost-benefit ratio for insurance/managed health care
    • purposes
  • Investigate new indications or formulations
  • Interested in surveying safety data in large
  • populations

Version: Final 31- Mar-2010


What is a protocol?

  • Recipe or overall master plan for the trial
