Key Market Insights

Clinical trials are a process of clinical research that is governed by a defined protocol which is carefully established to answer a precise patient care query. Clinical trials can be divided into five phases, with every phase playing a distinct purpose within the clinical trial. Every trial adheres to a procedure that designates what types of individuals may participate in the study.

The trials also outline exact plan of procedures, tests, medications, and doses within the trial apart from specifying the span of the study. In recent years, the costs associated with drug development have increased significantly, driving pharma and biotech companies to look for modernizations and smarter ways of conducting business.
