Informed Consent Form in Clinical Trials: Before a clinical trial begins, researchers must obtain permission from participants to include them in the study. This permission is given through an informed consent form. But what exactly is this form, and why is it important?
An informed consent form in clinical trials is a legally required document that provides detailed information about the study, including its purpose, procedures, risks, and benefits. It ensures that participants understand what they are signing up for and that their participation is voluntary.
Clinical trials are essential for developing new drugs, medical devices, and treatment methods. However, without informed consent, participants might unknowingly expose themselves to risks they do not fully understand. This is why ethical guidelines require every trial to have a well-structured informed consent form.

What is an Informed Consent Form?
An informed consent form in clinical trials is a document that provides participants with complete details about a research study before they decide to participate. It ensures that they are aware of all aspects of the trial, including any risks involved, so they can make an informed decision.
The Indian Council of Medical Research (ICMR) defines informed consent as:
“A process by which a participant voluntarily confirms their willingness to participate in a particular trial after being informed of all aspects relevant to their decision.”
This means that researchers must explain the study in simple terms so that participants fully understand what they are agreeing to.
Key Aspects of Informed Consent:
- Transparency: Participants must be given all necessary details about the study, including potential risks and benefits.
- Voluntariness: Participation should be completely voluntary, without any pressure or coercion.
- Comprehension: The document should be written in a way that is easy to understand, avoiding complex medical jargon.
Without informed consent, a clinical trial would be considered unethical and may not receive approval from regulatory authorities such as the Drugs Controller General of India (DCGI) or the Ethics Committee.
What is the Purpose of an Informed Consent Form?
The purpose of an informed consent form is to protect participants’ rights and well-being while ensuring transparency in research. It serves as a safeguard to ensure that individuals are fully aware of what the study involves before agreeing to participate.
Why is an Informed Consent Form Necessary?
- Protects participants from potential harm: Clinical trials involve testing new drugs or medical treatments, which may have unknown side effects. Participants need to be aware of these risks before agreeing to participate.
- Ensures voluntary participation: No one should be forced or misled into joining a clinical trial. The form guarantees that participation is entirely voluntary.
- Provides legal protection: Informed consent serves as legal proof that participants were given all necessary information before joining the study.
- Builds trust in research: Ethical research practices, including informed consent, help build public trust in medical studies and clinical trials.
Many clinical research training centers include detailed modules on informed consent in their clinical research courses to ensure that students understand its significance.
Parts of an Informed Consent Form
Every informed consent form must include specific sections to provide complete information to participants. The components of an informed consent form include:
1. Study Title and Researcher Information
- The official title of the clinical trial
- Name and contact details of the principal investigator and research team
2. Purpose of the Study
- Explanation of why the study is being conducted
- The expected outcome or objective of the research
3. Study Procedures
- Step-by-step details of what the participant will undergo during the study
- Duration of the study and number of visits required
4. Risks and Benefits
- A detailed list of possible risks and side effects of the treatment or intervention
- Potential benefits to participants and society
5. Confidentiality
- How participant data will be stored and protected
- Who will have access to the data
6. Participant Rights
- Right to ask questions and receive clear answers
- Right to withdraw from the study at any time without consequences
7. Signature Section
- Signature of the participant, researcher, and a witness
- Date of consent
A well-structured format of an informed consent form is essential to ensure clarity and compliance with ethical guidelines.
Example of an Informed Consent Form for Research Study

Why is Informed Consent Important in Clinical Trials?
Informed consent ensures that research is conducted ethically and that participants are fully aware of what they are agreeing to. Studies have shown that lack of proper informed consent has led to ethical violations in past clinical trials.
Many clinical research training centers, such as the Learning Labb Research Institute (LLRI), teach students how to draft proper informed consent documents in their clinical research courses.
