1. What are clinical trials ?
A type of research study that tests how well new medical approaches work in people. These studies test new methods of screening, prevention, diagnosis, or treatment of a disease. Before doing a clinical trial, investigators conduct preclinical

research using human cell cultures or animal models. For example, they might test whether a new medication is toxic to a small sample of human cells in a laboratory.

2. Why are they conducted ?
Clinical trials are conducted to evaluate if a drug is safe for consumption by

human beings and if it is actually effective in curing or preventing a medical condition or disease. Keep in mind, this will be the first time that the drug will be tested on human beings.

3. Phase 0 trials
Phase 0 trials are also known as human micro-dosing study.
