Why are clinical trials important???
Clinical trials are prospective research studies. Involving people. They test whether particular treatments are safe and how well they work. (‘Trial’ in this sense means testing something, and has nothing to do with legal trials or court cases).
Clinical research determines safety and effectiveness of medications, devices, diagnostic products and treatment regimens intended for human use
There are ethical and regulatory constraints for the design and conduct of clinical trial.The United states regulatory authority FDA review and approves the trials.Allied medical industries also do clinical trials and bring their treatment or medicines in market.
We need to know: Does a treatment work? Does it work better than other treatments? Does it have any side effects? Clinical trials are designed to answer these questions and improve health and quality of life for patients. Until well-designed trials have been carried out, we simply do not have enough evidence to know if a treatment is both effective and safe. Without trials, there is a risk that people will be given treatments which do not work and which may even be harmful.
Experimenting and testing have long been a part of medicine.
