The market growth spiked in 2020 owing to the COVID-19 pandemic. This growth pattern was witnessed by both virtual clinical trials and traditional ones. Several companies invested heavily in novel drug development to minimize COVID-19 patient burden. One such example being, in 2020, Synairgen plc and Parexel collaborated on a Phase III study of Interferon-beta (IFN-beta) treatment for COVID-19. Furthermore, rapid technological evolution, rising prevalence of chronic diseases, globalization of clinical trials, penetration of personalized medicine and a rise in demand for CROs for conducting research activities is expected to positively impact the market growth.

In addition, the COVID-19 pandemic led to changing the ways of conducting upcoming or ongoing clinical trials. Regulatory agencies including the U.S. FDA, the European Medicines Agency (EMA), the National Institutes of Health (NIH), and China’s National Medical Products Administration among several others issued various guidelines for conducting trials during the pandemic to support the implementation of decentralized clinical trials and virtual services. The current scenario for research and development activities across the globe and the need for several new treatment options have also led to the adoption of fast-track clinical trials. Thus, aforementioned factors are estimated to offer new avenues to the clinical trials market growth.

Favorable government support and initiatives is another aspect boosting the market growth potential. For instance, the WHO launched Solidarity, an international clinical trial to determine effective treatment against COVID-19. [PS2]  It includes comparing four treatment options against the standard of care to evaluate their effectiveness against the coronavirus. In May 2020, the WHO also announced an international alliance for simultaneously developing multiple candidate vaccines to prevent the spread of the coronavirus disease, calling this effort the Solidarity trial for vaccines.

Furthermore, the use of CRO services helps manufacturers/sponsors pay complete attention to the production capacity and enhance their in-house processes. The availability of the vast array of services from drug discovery to post marketing surveillance has further simplified processes for mid-size & small-scale pharmaceutical and biotechnological organizations by providing them the option to outsource research and development activities to reduce infrastructure investment. For instance, in November 2023, Syneos Health signed an agreement with GoBroad Healthcare Group. This collaborative initiative extended the company’s clinical trial capabilities into a more extensive array of therapeutic areas in China.
