What Are Clinical Trials and Studies?
A clinical trial is a meticulously planned research study to determine the efficacy and safety of both new and established medical treatments. Studies may concentrate on pharmaceuticals, medical equipment, surgical techniques, or patient behavior.
A clinical trial is frequently performed to determine whether a novel treatment is more efficient than the current treatment and/or has fewer negative side effects. Other clinical studies examine methods for detecting diseases early on, often even before symptoms appear. Others research strategies to avoid a health issue.
Two General Types of Clinical Trials
Clinical research is a term used to describe human subjects-based medical research. There are two types: clinical study and observational study. Observational study looks at people in a typical setting. By classifying the volunteers according to their overall traits and contrasting recent changes, researchers compile the data. Researchers frequently utilize health data to assess if certain lifestyle choices have a substantial influence on the health of cognitive functioning. A significant potential for clinical research may be presented by this study.
What is the meaning of randomized controlled trial?
In a randomized controlled trial (RCT), the population receiving the program or policy intervention is randomly selected from the eligible population, and a control group is also randomly selected from the same eligible population in a randomized controlled trial (RCT), which is an experimental type of impact evaluation.

Phase 1 Trial Definition
What is a Phase 1 clinical trial?
Phase I trials of a novel medicine are often the first to involve humans. Phase I trials are conducted to determine the greatest dose of a new medication that can be administered safely without generating serious negative effects.
What is the difference between a Phase 1 and Phase 2 trial?
Phase 1: Initial human testing, largely to ensure safety. A medication is administered to a small group of healthy volunteers who are carefully observed. Phase 2: Testing on a limited number of patients to check safety, monitor how a medicine is metabolized, and collect preliminary effectiveness data.
What is a Phase 2 trial?
A phase 2 trial is a research that determines if a novel therapy for a specific form of cancer or other disease is effective (for example, whether it shrinks a tumor or improves blood test results). Phase II clinical studies may also give more information about the new treatment’s safety and how it affects the body.
How does FDA define a clinical trial?
Clinical trials are voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments. Source: Clinical Trials: What Patients Need to Know.
The Importance of Clinical Trials for You and Your Health
- Diagnose illnesses and other health issues.
- Reduce the number of persons who get ill by preventing illness onset or recurrence.
- Treat sickness to enhance survival rates or the number of individuals cured.
