Regional Analysis
North America emerged as the leading region in the global AI in clinical trials market, accounting for a significant market share of 31.5% in 2024. This dominance is largely attributed to the strong presence of established pharmaceutical companies such as Abbott Laboratories, Johnson & Johnson, and Pfizer, along with rising research and development expenditures. The region also benefits from a large and well-developed network of clinical trial service providers and increased investments in biosimilars and biologics, which have supported the adoption of AI-driven solutions in clinical research.
In addition, continuous innovation by regional startups has reinforced market growth. For example, bfLEAP, a proprietary artificial intelligence platform developed by U.S.-based startup Bullfrog AI, has been introduced to advance precision medicine by improving data-driven decision-making in clinical trials.
Meanwhile, the Asia-Pacific region is expected to register the fastest growth rate, projected at 31.5% during the forecast period. This accelerated expansion is supported by the growing adoption of AI-based tools, favorable government initiatives promoting AI integration across healthcare, and increasing clinical trial activity. Moreover, the region offers a large and diverse patient population and comparatively lower trial costs, resulting in higher clinical trial enrollment levels than those observed in Europe and North America.
Use cases
- Protocol design optimization
- What AI does: Scans past trial protocols and outcomes to suggest fewer visits, fewer tests, and clearer endpoints.
- Why it matters (numbers): More than 40% of trials were reported to amend the protocol before the first subject visit, causing about 4 months of delay.
- Typical KPI targets: fewer amendments, shorter start-up time, fewer procedures per patient.
- Inclusion/exclusion criteria tuning
- What AI does: Tests criteria rules against real patient data (EHR/RWD) to see how many eligible patients actually exist.
- Why it matters (numbers): ~80% of trials were reported to fail the initial enrollment target and timeline (recruitment is a major cause).
- Typical KPI targets: higher screen-to-enroll rate, lower screen failure rate, faster enrollment curve.
- Feasibility forecasting
- What AI does: Predicts if the trial can recruit enough patients in each country/site based on patient pools and competition.
- Why it matters (numbers): 11% of research sites were reported to enroll zero participants, and 37% under-enroll.
- Typical KPI targets: fewer non-performing sites, higher enrollment per active site.
- Site selection and site ranking
- What AI does: Ranks sites using past enrollment performance + local patient availability signals.
- Why it matters (numbers): A real-world dataset example showed 19% of investigator sites enrolled only one patient, contributing <3% of enrolled patients; meanwhile the top 16% of sites delivered 54% of enrollments.
- Typical KPI targets: higher patients/site, fewer low-output sites, shorter time to full enrollment.
- Patient finding from EHRs
- What AI does: Uses rules + natural language processing to read clinical notes and match patients to eligibility criteria.
- Measured impact (numbers): An AI screener (ACTES) reduced patient screening time by 34% and improved patient enrollment by 11.1%.
- Typical KPI targets: faster prescreening, higher “approached-to-consented” rate, lower coordinator workload.
- Recruitment acceleration and prediction
- What AI does: Predicts enrollment in real time and flags sites that are likely to miss targets.
- Measured impact (numbers): Industry pilot analysis reported AI/ML can boost enrollment by ~10–20% and predict enrollment performance for earlier intervention.
- Typical KPI targets: fewer enrollment stalls, shorter “time to last patient in”.
- Diversity and representation targeting
- What AI does: Maps where eligible patients live (geo + care pathways) and suggests site locations and outreach channels.
- Why it matters (numbers): When many sites under-enroll (e.g., 37%) and some enroll none (11%), broadening effective site coverage becomes critical.
- Typical KPI targets: share of enrolled patients from priority groups, balanced recruitment by region.
- Trial start-up automation
- What AI does: Drafts essential documents, checks completeness, and flags missing data for faster activation.
- Why it matters (numbers): Delays are expensive: updated Tufts analysis indicates mean direct cost per day is about $40,000/day for Phase II–III, with Phase III ~$55,716/day and Phase II ~$23,737/day.
- Typical KPI targets: shorter site activation time, fewer rework cycles, fewer missing documents.
