Clinical Trials Support Services Market To Reach $47.00 Billion By 2033

Clinical Trials Support Services Market Growth & Trends

The global clinical trials support services market size is expected to reach USD 47.00 billion by 2033, registering a CAGR of 7.93% from 2026 to 2033, according to a new report by Grand View Research, Inc. Increasing the number of CROs offering clinical trial support services, and huge investment in research & development by the pharmaceutical and biopharmaceutical companies are the key factors driving the market growth. The industry felt the impact of the COVID-19 pandemic. The pandemic disrupted the supply chain to a severe extent in 2020. However, it also revealed ways to grow, either through M&A or through the adoption of digital technologies in clinical research.

Clinical trials encounter some concerning statistics, such as 85% of the clinical trials fail to recruit enough participants, 80% are delayed due to recruiting challenges, and the rate of dropout of participants is increasing. However, to overcome this, a patient retention strategy that is engaging and gives clarity is required. It is critical to ensure that the informed consent materials are simple to grasp. According to a CISCRP study, 35% of trial participants who later dropped out stated that informed consent was difficult to comprehend. An average American is 7th to 8th grade educated, and it is critical to guarantee and analyze the material’s readability before submitting it to the Institutional Review Board (IRB).

Adoption of virtual clinical trials across the clinical trials support services industry is one of the major factors that has boosted revenue growth post-pandemic. An increasing number of clinical research organizations are focusing on the adoption of virtual technologies to streamline their clinical research services. According to the latest Annual CRO Report by the Veeva Unified Clinical Operations Survey, CROs are making significant advancements to speed up and modernize clinical trials. Findings from Veeva Systems reflect that CROs have taken decisive action to streamline trial execution by adopting new technologies and digital strategies that replace manual processes, eradicate information siloes, and enable trial collaborations.
