Clinical Trials Market Size & Outlook, 2025-2033

Clinical Trials Market Size

The global clinical trials market size was valued at USD 76.70 billion in 2024 and is projected to grow from USD 80.71 billion in 2025 to reach USD 132.05 billion by 2033, exhibiting a CAGR of 6.3% during the forecast period (2025-2033). 

Clinical trials are carefully designed research studies that test how well medical interventions, such as new drugs, therapies, or medical devices, work in humans. They are essential for determining the safety and effectiveness of treatments before they are widely used.

These trials are conducted in phases, each serving a unique purpose:

• Phase 1: Focuses on safety, testing a new treatment on a small group to evaluate side effects and dosage.

• Phase 2: Assesses the treatment’s effectiveness while continuing to monitor safety.

• Phase 3: Compares the new treatment to existing options in a larger group of participants.

• Phase 4: Conducted after the treatment is approved, it monitors long-term effects and safety.

Clinical trials follow strict protocols and are overseen by regulatory bodies to ensure participant safety and scientific accuracy. These studies rely on the voluntary participation of individuals who meet specific eligibility criteria, often giving participants access to cutting-edge treatments. The major factors propelling the expansion of the global clinical trials market are the surge in global healthcare needs, especially for chronic and complex diseases, and the growing focus on personalized and precision medicine.

Clinical Trials Market Trends

Adoption of Decentralized Clinical Trials (dcts)

DCTs involve conducting trials outside traditional clinical settings, using technologies like telemedicine, wearable devices, mobile apps, and eConsent. This enables remote patient participation, improving access, enhancing recruitment, reducing dropout rates, and speeding up trial timelines.

• For example, Pfizer's fully virtual trial for Atopic Dermatitis used mobile technology to enable remote patient monitoring and virtual consultations, aligning with the DCT approach to improve accessibility and efficiency.

Thus, DCTs enhance accessibility, streamline processes, and improve patient retention, making clinical research more efficient and inclusive.

Shifting Focus to Patient-Centric Trial Designs

Patient-centric trial designs focus on improving the overall experience for participants, ensuring their needs, preferences, and well-being are central to the trial process. This approach includes flexible protocols, personalized care, and the use of technology to enhance communication and reduce participant burden.

• For example, Janssen's "Patient Voice in Clinical Trials" program actively involves patients in the trial design process, gathering their input to improve trial protocols, enhance patient engagement, and ensure the trials better align with their needs and preferences.

Thus, patient-centric trial designs enhance participant experience, drive better engagement, and improve clinical trial outcomes.

Thus, the upward trend highlights the increasing demand for clinical trials driven by the need for novel therapies, advancing technologies, and expanding research initiatives across various therapeutic areas, ultimately contributing to the growth of the clinical trials market.

Globalization of Clinical Trials

The globalization of clinical trials propels market expansion by enabling access to diverse patient populations, reducing recruitment challenges, and lowering costs. It accelerates study timelines and fosters multinational collaborations, leading to faster regulatory approvals and broader market access for new therapies.

• As per the data published by the WHO in June 2024, the number of trials registered in the Western Pacific (23,250) was around 14 times higher than that in Africa (845). This disparity is largely due to the substantial number of trial registrations in China, driven by the increasing number of Chinese journals, government funding agencies, universities, and hospitals that require trial registration.

Thus, the globalization of clinical trials accelerates market growth by expanding patient access, reducing costs, and fostering international collaboration for faster drug development.

Market Restraining Factor

Patient Recruitment and Retention Issues

Patient recruitment and retention remain critical challenges in the clinical trial industry, significantly hindering the speed and success of drug development. A shortage of participants or high dropout rates disrupt trial timelines, compromise data integrity, and increase costs.

• According to a whitepaper by the Emmes Company, LLC (September 2023), over 85% of clinical trials fail to retain sufficient participants until study completion.

• Similarly, an article by Md Group (October 2020) reported that approximately 30% of patients drop out before completing trials due to financial strain, time conflicts, lack of understanding or engagement, long-distance travel, stress, anxiety, and family commitments.

These dropouts result in delays, loss of critical data, and the financial burden of recruiting replacements. As highlighted by MJH Life Sciences (April 2023), the average cost to replace one lost participant is $19,533, further straining the recruitment process.

Addressing these challenges is vital to enhancing the efficiency, cost-effectiveness, and success rates of clinical trials. Improved patient engagement strategies, financial support, and flexible scheduling can help mitigate these issues.

Market Opportunities

Expansion of Contract Research Organizations (cros)
