Top 5 Questions About Clinical Trials

Short Description

1 – How did clinical trials begin?

Evidence of recorded trials dates back to biblical times, and elements of controlled trials were seen as early as the 1700s. The groundbreaking streptomycin (a type of antibiotic) trial of 1946 was the ‘landmark trial for the model of meticulousness in design and implementation of research,’ says Dr. Arun Bhatt.

As ethics for human protection advanced in the sciences, so did the number of volunteers, continuing the growth of research and trials. Clinical trials today have evolved into standardized procedures to regulate treatments.

2 – What is a clinical trial?

The National Library of Medicine explains a clinical study as “research using human volunteers that is intended to add to medical knowledge.” This knowledge can be related to the treatment, diagnosis, or prevention of diseases and conditions. The main goal of a clinical trial is to determine the safety and efficacy of a medical intervention by measuring certain outcomes in the participants.

There are two main types of clinical studies: interventional studies and observational studies.

According to the National Cancer Institute, “an observational study is a type of study in which individuals are observed or certain outcomes are measured. No attempt is made to affect the outcome (for example, no treatment is given).”

Oppositely, during an interventional study, participants receive specific interventions according to the research plan, typically created by a medical doctor. These interventions may be medical products, such as drugs or devices; procedures; or changes to participants’ behavior, such as diet.

3 — Who is involved in a clinical trial?

Clinical studies highly trained research teams; this includes doctors, nurses, social workers, and other health care professionals.

4 — Where do clinical trials take place?

Study location depends on who is conducting the study. Clinical studies can take place in universities, doctors’ offices, and community clinics.

5 — How long do clinical trials last?

The length of a clinical study can vary. However, participants who qualify for a clinical trial will always be informed about the study duration before they enroll.

Frequently Asked Questions

What is a clinical trial?

A clinical trial is a research study designed to help researchers learn more about health conditions, treatments, prevention methods, or medical products. Clinical trials follow structured protocols and are conducted under regulatory oversight.

Why do people participate in clinical trials?

People participate in clinical trials for many reasons, including contributing to medical research, learning more about their health, or helping advance future treatment options. Participation is always voluntary.

Is participating in a clinical trial safe?

Clinical trials are reviewed and monitored by regulatory authorities and ethics committees to help protect participant safety. Each study includes specific safety guidelines and an informed consent process.

Do I have to participate if I sign up on this website?

No. Submitting your information allows us to notify you about studies that may be relevant to you. You are never required to participate in any study.

What happens after I submit my information?

After you submit your information, you may be contacted if a clinical research study becomes available that matches your interests and basic eligibility. You can decide whether or not to learn more at that time.

Will I be contacted for every study?

No. We only reach out when a study may be relevant based on the information you provided and the study’s eligibility criteria.

Is there a cost to participate in a clinical trial?

Many clinical research studies cover study-related procedures, but details vary by study. All information is provided before any decision to participate is made.

Will I receive treatment if I join a study?

Clinical trials may involve investigational treatments, standard care, or observation only, depending on the study. Participation does not guarantee access to treatment.

Can I leave a clinical trial after joining?

Yes. Participation in a clinical trial is voluntary, and participants can choose to withdraw at any time.

Who runs clinical trials?

Clinical trials are conducted by research institutions, healthcare providers, pharmaceutical or medical device companies, and contract research organizations.

How do I know if a study is right for me?

Each study has specific eligibility criteria and participation requirements. You will receive detailed information before deciding whether to participate.

Why should I provide my contact information?

Providing your contact information allows us to notify you when clinical research opportunities become available that may be relevant to you. There is no obligation to participate.
