Clinical trials: Trials to evaluate the effectiveness and safety of medications or medical devices by monitoring their effects on large groups of people.. Clinical research trials may be conducted by government health agencies such as NIH, researchers affiliated with a hospital or university medical program, independent researchers, or private industry. These treatments investigate promising new drugs, drug combinations, new approaches to surgery or radiation therapy, and advances in new areas such as gene therapy. Some even look at ways to prevent diseases from happening. Definition and Purpose of Phase 1 Clinical Trials . This is known as blinding, and it helps reduce the effects of bias when comparing the outcomes of the treatments. Dr. Chintan Doshi 2. The difference between NIH’s Definition of a Clinical Trial (CT) and what FDA will consider a CT under the requirements of its Investigational New Drug (IND) or Device Exemption (IDE) Process affects a small number of NIH applications proposing certain types of research. What exactly is meant by the term ‘clinical trial’? They are the primary way that researchers find out if a new treatment, like a new drug or diet or medical device (for example, a pacemaker) is safe and effective in people. Phase III trials, often multicenter, involve thousands of volunteers, randomly assigned to control and study groups.

For example, the research may aim to learn if a device is harmful to living tissue. The earliest phase trials may look at whether a drug is safe or the side effects it causes. Safety must be monitored carefully over the first few years of a newly licensed treatment. The local ethics committee has discretion on how it will supervise noninterventional studies (observational studies or those using already collected data). A clinical trial compares the effects of 1 treatment with another. For example, both groups should have people of a similar age, with a similar proportion of men and women, who are in similar overall health. The medicine is tested in larger groups of people who are ill, and compared against an existing treatment or a placebo to see if it's better in practice and if it has important side effects. If the researchers do not offer you the results and you want to know, ask for them. Individuals are assigned randomly to a treatment group (experimental therapy) and a control group (placebo or standard therapy) and the outcomes are compared. They may explore specific pharmacologic effects, adverse reactions, or long-term effects.
