2. DEFINITION
PROPOSAL:
• A document to support an application for
approval from institution to conduct a study and
obtain funding.
PROTOCOL :
• A study’s detailed methodology.
• A simplified protocol is usually part of a research
proposal but is not detailed enough to qualify for
ethical review.

control), experimental (randomized control trial,
interventional case series)
Timing - prospective, retrospective
State the study endpoints / variables

Interventional study – describe the intervention used
If relevant, include:
Number of study groups, ratio of subjects in control &
treatment group
Specify randomization or blinding if relevant
Types, quantity & frequency of biospecimens collected
Describe the instruments used i.e questionnaires
(validated?), interviewers (well-trained?)

Include assumption if necessary
ESSENTIAL COMPONENTS OF A
PROTOCOL
19. 3.10 & 3.11
Relevant for prospective studies which require informed
consent i.e survey, interventional studies - especially RCT
3.10 Risk and benefit to study participants
Identify potential / real risks
Example: There are no serious side effects known to be
caused by the investigational product. The study procedures
are all routine procedures for the condition studied.
Include benefits to participant / overall research
Example: This study does not present any direct benefit to the
participants but may provide a better understanding of the
condition studied.
ESSENTIAL COMPONENTS OF A
PROTOCOL
20. 3.11 Risk Benefit Assessment
Provide a brief risk benefit assessment
Strong justification - if the risk outweighs the benefits
State how study related injuries are treated & who pays for
the treatment
Example:
There is minimal risk from the investigational product and
study procedures. Study findings shall greatly improve
treatment outcomes. The expected benefit outweighs the
minimal risk and thus this study should be supported. If any
injuries occur as a result of participating in the study,
treatment for shall be provided or paid for by the sponsor.
