Clinical Trial Investigative Site Network Market Overview

Clinical trials are conducted in several phases to answer specific questions and ensure the safety of participants. These trials are carried out in accordance with the Good Clinical Practice (GCP) guidelines mandated by regulators to protect patients. Generally, a new treatment is tested in three to four phases of clinical trials before regulatory agencies consider it safe and effective. Clinical trials provide valuable information on the potential treatment, its associated risks, and various aspects of the patient's quality of life.

The clinical trial investigative site network market encompasses collaboration between contract research organizations (CROs) and sponsors for conducting clinical trials. Clinical investigational site networks are a group of independent clinical sites that meet certain qualifying criteria and work as a single entity, saving R&D expenses. Research centers, clinics, hospitals, and other specialized facilities that fulfill the precise trial standards can be used as sites. These sites are independently owned and operated, which distinguishes investigative site networks from other outsourcing businesses, such as contract research organizations and site management firms.

Clinical Trial Investigative Site Network Market Dynamics

Driver: Increase in the number of clinical trials 

The rise in the number of clinical trials is a major driving factor accelerating the growth of the clinical trial investigative site network market. Clinical trials assist in advancing patient treatment and medical care. Clinical trials are also used to test new diagnostic techniques for diseases, often even before their first symptoms start to harm the body. Clinical trials may also be conducted to test methods of disease prevention. Clinical trials may also evaluate the efficacy of strategies intended to help those with chronic illnesses or life-threatening diseases feel better physically.

Clinical trials are typically governed by ethics committees and health authorities such as the European Medicines Agency (EMA), the Pharmaceuticals and Medical Devices Agency (PMDA) in Japan, the U.S. Food and Drug Administration (FDA), and others. Hiring a clinical trial investigative site network empowers the regulatory function and improves the enrollment of participants, data management, and quality assurance. It enhances process compliance, reduces issues associated with each trial, and assists with faster trial initiations and shorter trial periods. Therefore, the increasing incidence of chronic diseases around the globe has resulted in a rise in several clinical trials, propelling the growth of contract research organizations.

  • In 2024, ClinicalTrials.gov currently lists 492,037 studies with locations in all 50 States and 223 countries, and in 2020 it was 362,469. The clinical research landscape continues to expand at a substantial rate. The growth in the number of registered studies is mainly due to the rising number of diseases being studied, advancements in medical technology, growing demand for personalized medicine, and increasing need for advanced treatments and vaccines in response to global health crises like the COVID-19 pandemic.
