Current Scenario of the Global Clinical Trials Market

Clinical trials are a type of research that studies new tests and treatments by evaluating their effects on human health outcomes. Most people volunteer to participate in clinical trials to test medical interventions, including drugs, cells, and other biological products, surgical procedures, radiological procedures, devices, and preventive care. Clinical trials consist of four major phases, which are carefully designed, reviewed, and completed and need to be approved before the start of the procedure. The global clinical trials market accounted for significant growth and is anticipated to have notable growth during the forecast period. Companies' increased focus on developing novel treatments for chronic diseases and the escalating demand for outsourcing R&D activities are the primary factors driving market growth. According to the U.S. National Library of Medicine, as of June 2023, approximately 55,483 interventional clinical studies were posted with results on the official website Additionally, according to the World Health Organization, by 2022, approximately 39% of clinical trials were done for non-communicable diseases across the globe, whereas 60% of clinical trials are for infectious diseases.


The growing patient population of chronic diseases, increasing advances in biotechnology and personalized medicine, rising demand for innovative treatment options and the expansion of contract research outsourcing are majorly driving the growth of the clinical trials market.

Technological advancements, increasing demand for innovative solutions in the healthcare industry, and boosted alliances between the pharma-biotech companies and clinical research organizations are primarily driving the growth of the global clinical trials market. Ongoing research to ensure better treatment procedures for the patient's well-being is a significant factor that is opening growth opportunities for the global clinical trials market. The rise in the scale of pharmaceutical and biopharmaceutical companies is to surge growth opportunities for the global clinical trials market. The growing patient flow in hospitals and clinics is resulting in an increasing demand for effective treatment options, which is eventually contributing to an increasing number of clinical trial activities and propelling the global market growth.

Additionally, growing support from government and non-government organizations in real-time applications is significantly promoting global market growth. The growing prevalence of personalized medicine in urban areas is fueling the growth of the clinical trials market. The acceptance of the latest technological developments and the launch of innovative products are spurring the market's growth rate. Furthermore, rising urbanization across the world is prompting the growth rate of the Global Clinical Trials Market to an extent.


Rapid changes in economic strategies are quietly restraining the demand of the global clinical trial market.

The lack of skilled persons to operate devices in organizations is a challenging thing for the market's growth. Small-scale industries cannot afford vast amounts of installation and maintenance of the latest tools, which is also a factor limiting the growth rate of the global clinical trials market. Factors such as lack of skilled professionals to operate advanced CTMS solutions and budget constraints of small- and medium-sized pharmaceutical and biotechnology companies and small CROs limit the market growth to a considerable level.

Impact Of COVID-19 On the Global Clinical Trials Market

[April 2020] Clinical trials are put on the fast track to contain the spread of the coronavirus. In general, a regular vaccine takes 10-15 years to come onto the market. Still, due to the emergency caused by COVID-19, approximately six experimental vaccines are moving forward into the human trial stage within just six months. World Healthcare Organization (WHO) announced that 83 companies are researching to figure out a vaccine for COVID-19, where 77 companies are already in the pre-clinical evaluation phase, on April 23, 2020. Surveys also suggest that the coronavirus outbreak may not be typical until the drug or vaccine comes into the market. Experts say that the vaccine may be ready by 2021 as some work has already been done to develop a vaccine for other diseases caused by a coronavirus.

Clinical trials need to have real-time data and detailed information regarding the impact of the virus on the human body. Leading companies are identifying the indicators to create a solution to prevent the spread of this disease. On April 23, 2020, BioNTechSE announced that it received approval for the phase l/ll clinical trial of the BNT162 vaccine. This company has joined hands with Pfizer in developing this program to prevent COVID-19. BNT162 is the first clinical trial to receive approval, and experiments will soon be conducted in the U.S. with regulatory approval. The partnership between these companies is enhancing the speed of the development. Also, BioNTechSE is merging with Fosun Pharma, a leading biopharma company in China, to improve the development of the vaccine. The collaboration between the BioNTechSE and Fosun Pharma is also to elaborate on the development of the vaccine. These companies are to conduct clinical trials shortly.

Global Clinical Trials Market Analysis By Phase

Based on the phase, the Phase III trials segment accounts for a market share of 53% in the global clinical trials market. The segment growth is majorly driven due to the growing per capita income, particularly in developed and developing countries. The growing number of patients with rare diseases is further propelling the growth of the phase III trials segment in the global market. 

Phase II trials follow Phase III trials in much of the global market share and accounted for a market share of 18.9% in 2023. Phase II plays a vital role in cancer-related research. Rising disposable income in urban areas and the growing prevalence of quality treatment procedures are escalating the growth of this segment. 

Global Clinical Trials Market Analysis By Design

The segment of interventional trails has had a tremendous growth rate over the past few years and occupied a share of 45% in terms of revenue in 2023. Increasing focus on developing new procedures for different diseases is leveraging the demand of the market. Increasing the scale of laboratories with the latest equipment and developing quality drugs is broadening the need for the clinical trials market. Furthermore, the concentration on developing new methods to treat various diseases and increasing demand for intervention by key players for clinical trials research.
