What are Clinical Trials?

Clinical trials are research studies performed in people that are aimed at evaluating a medical, surgical, or behavioral intervention. They are the primary way researchers determine if a new form of treatment or prevention, like a new drug, diet, or medical device, is safe and effective. Think of them as carefully controlled experiments designed to answer specific questions about a treatment.

These trials are a critical part of medical advancement, providing the evidence needed to improve healthcare and develop new treatments for diseases affecting us all. In India, with its diverse population and unique healthcare challenges, clinical trials play a particularly vital role in finding solutions tailored to the needs of Indian patients. Academic clinical trials, initiated by researchers for academic purposes like exploring new uses for existing drugs, also contribute significantly to medical knowledge.

Key Facts:

• Clinical trials involve human participants.
• They assess the safety and effectiveness of new treatments or interventions.
• They follow strict protocols and ethical guidelines.
• The Central Drugs Standard Control Organization (CDSCO) regulates clinical trials in India.
• Participation is voluntary and requires informed consent.

Why are Clinical Trials Performed?

Clinical trials are conducted to:

• Evaluate the safety and efficacy of new drugs, medical devices, or therapies: Are they safe for human use? Do they actually work?
• Compare new treatments to existing ones: Is the new treatment better, worse, or about the same as what's currently available?
• Find new ways to use existing treatments: Can an existing drug be used to treat a different condition or be administered in a different way?
• Improve medical knowledge: Expand our understanding of diseases and how they respond to treatment.
• Develop new treatment options specifically for Indian patients: Considering the genetic and environmental factors unique to the Indian population.

Main Conditions/Indications: Clinical trials are conducted for a wide range of conditions, including:

• Cancer
• Heart disease
• Diabetes
• Infectious diseases (e.g., tuberculosis, HIV)
• Neurological disorders (e.g., Alzheimer's disease, Parkinson's disease)
• Mental health conditions (e.g., depression, anxiety)
• Rare diseases

When Doctors Recommend It:

Doctors may recommend participating in a clinical trial when:

• Standard treatments have not been effective.
• A new treatment shows promise and is not yet widely available.
• The patient is interested in contributing to medical research.
• The patient meets the eligibility criteria for a specific trial.
• A doctor believes that a new treatment being tested may offer a better outcome than current standard treatments.
