Clinical trials are conducted to collect data regarding the safety and efficacy of new drug and device development. Clinical trials look at new ways to prevent, detect, or treat disease. Treatments might be new drugs or new combinations of drugs, new surgical procedures or devices, or new ways to use existing treatments. The goal of clinical trials is to determine if a new test or treatment works and is safe.
Clinical trials can also look at other aspects of care, such as improving the quality of life for people with chronic illnesses. The different types of clinical trials are Natural history studies, Prevention trials, screening trials, diagnostic trials, treatment trials and quality of life trials. There are four phases of human clinical trials i.e.
• Phase I- assess the safety of a drug or device.
• Phase II- test the efficacy of a drug or device.
• Phase III- involve randomized and blind testing in several hundred to several thousand patients.
• Phase IV- Post Marketing Surveillance Trials conducted after a drug or device has been approved for consumer sale.
