Clinical Research While preclinical research answers basic questions about a drugs safety it is not a substitute for studies of ways the drug will interact with the human body. Phase III Clinical Trial Phase III studies are done to study the efficacy of an intervention in large groups of trial participants from several hundred to several thousand by comparing the intervention to other standard or experimental interventions or to non-interventional standard care. Phase 3 clinical trials are designed to test whether the investigative treatment is better than the standard clinical method for the targeted health condition.

One group receives drug A during the initial phase. Researchers design clinical trials to answer specific research questions related to a drug candidate. Clinical trials follow a rigorous series from early small-scale Phase 1 studies to late-stage large scale Phase 3 studies.

Phase 3b Clinical Trial means a human clinical trial of the Licensed Product that a is voluntarily conducted after the filing with the FDA of the NDA for the Licensed Product but prior to obtaining Regulatory Approval of such NDA and b is not required or requested by the FDA as a condition of or in connection with obtaining such Regulatory Approval.

When phase 3 clinical trials or sometimes phase 2 trials show a new drug is more effective and safer than the current standard treatment a New Drug Application NDA is submitted to the Food and Drug Administration FDA for approval. Clinical trials are studies intended to discover or verify the effects of one or more investigational medicines. The regulation of clinical trials aims to ensure that the rights safety and well-being of trial subjects are protected and the results of clinical trials are credible.

For example two-by-two cross-over assignment involves two groups of participants. After successful conclusion of these clinical trials it will receive formal approval from the FDA. In the United States when phase III clinical trials or sometimes phase II trials show a new drug is more effective or safer than the current treatment a new drug application NDA is submitted to the Food and Drug Administration FDA for approval.
