Guideline for Writing Clinical Research Study Protocol
A clinical research study proposal is a structured plan outlining the rationale, objectives, methodology, and expected outcomes
of a research project. The proposal should be scientifically important for securing appropriate approvals,
funding, and ensuring a scientifically sound study.
A good protocol starts with a strong idea and ends with a clear, feasible plan that can be executed exactly as written in the protocol.
Following steps should be considered while writing a protocol:
Establish a Strong Research Rationale
Before drafting a protocol, ensure that your research idea has a clear scientific basis. Your study
should aim to:
- Bridge a knowledge gap in the field.
- Explore a new or under-researched area.
- Validate or challenge previous findings using a larger or more robust study design.
Why this matters: Without a strong rationale, the study may fail to gain ethics
approval or funding. Review whether your idea genuinely adds to existing knowledge.
Define the Research Question & Objectives
The research question is the important part of your study. It should be specific, focused, and
answerable. Consider the FINER criteria (Feasible, Interesting, Novel, Ethical, Relevant). Clearly
state primary and secondary objectives, and define your hypothesis.
- What is the clinical problem?
- Does it meet the FINER criteria?
- Feasible
- Interesting
- Novel
- Ethical
- Relevant
- What are your primary and secondary objectives?
- What is your hypothesis?
Example:
- Research Question: Does Drug X reduce symptoms in patients with Disease Y compared to
placebo?
- Primary Objective: Evaluate Drug X’s effect over 12 weeks.
- Secondary Objective: Assess its safety profile.
Why this matters: If your question is too broad or vague, the study risks becoming
unmanageable or inconclusive.
Conduct a Literature Review
Review existing knowledge and identify gaps your study will address. A strong literature review
demonstrates understanding of the field and justifies the need for your research.
- Shows you understand the field.
- Demonstrates why your study is necessary.
- Helps refine your methodology.
Why this matters: Reviewers and funders want to see that your work builds logically
on what is already known.
Describe the Study Design & Methodology
Explain in detail the design and how the study will be carried out. Following points should be
considered while drafting the study design and methodology:
- Study type: RCT, cohort, cross-sectional, case-control, etc.
- Population: Inclusion and exclusion criteria.
- Intervention & comparator: Dosage, frequency, mode of administration.
- Outcomes: Clearly define primary and secondary endpoints.
- Sample size calculation: Include justification.
- Follow-up plan: Timing and frequency of assessments.
- Randomization & blinding: If applicable, describe the process.
Why this matters: Clarity here ensures the study is reproducible and minimizes
bias.
Address Ethical Considerations
Ethics must be central to the protocol. Hence while drafting the protocol one should ensure that the
patient’s right, safety and confidentiality of patients is protected by ensuring the following
points:
- Detailed Informed Consent Form available in English and local language.
- How you will obtain informed consent.
- Plan for IEC (Institutional Ethics Committee) approval.
- Measures for participant safety and monitoring.
- Data protection and privacy compliance.
Why this matters: Unethical studies risk rejection by ethics committees and can
compromise both participant safety and the credibility of the research team.
Develop the Statistical Analysis Plan
Detail information on how you will analyze the data, including your justification and methods used
for sample size.
- Statistical tests for each endpoint.
- How you will handle missing data.
- Interim analysis plans.
- Subgroup analyses (if planned).
Why this matters: A well-planned statistical section avoids biased interpretations
and strengthens credibility.
Create a Project Timeline
Provide a realistic schedule of activities from start to finish. Using a Gantt chart is highly
recommended.
Prepare a Detailed Budget
Budget all the expenses that will be required during the conduct of entire study. To complete the
study with the planned budget requires futuristic and realistic budget planning.
- Personnel salaries.
- Laboratory or imaging tests.
- Equipment or drug costs.
- Data management and software.
- Travel, logistics, and contingencies.
- IEC Fees (Applicable only for pharma sponsored studies)
- Institutional Over heads (Applicable only for pharma sponsored studies)
- Applicable taxes for pharma sponsored studies
- Archival charges (Applicable only for pharma sponsored studies)
Reference Your Sources
Use a consistent citation style (e.g., Vancouver or APA) for all literature and supporting
documents. This demonstrates academic integrity and credibility.
Note: A well-written protocol should be so clear that another researcher could
replicate your study without asking you a single question. Treat it like a recipe — precise,
complete, and easy to follow.
Details of documents to be included in the protocol (ICMR 2017)
| Document Details |
- The face page carrying the title of the proposal with signatures
of the investigators.
|
- Brief summary/lay summary.
|
- Background with rationale of why a human study is needed to answer
the research question.
|
- Justification of inclusion/exclusion of vulnerable
populations.
