In a market with 5,500+ clinical trials targeting a limited pool of gastroenterology patients, Clariness is the right recruitment partner to ensure your study reaches the right patients ahead of your competition.
At the core of successful gastroenterology clinical trials
2.9 billion people live with digestive diseases, yet recruitment isn’t straightforward:
- Diagnosis delays create narrow recruitment windows
- Trial eligibility often hinges on subjective scoring
- GI specialists are scarce globally, reducing diagnosed patient pools
With more than 20 years of experience, Clariness has supported gastroenterology clinical trials across common and rare gastrointestinal indications, spanning Phase I to Phase IV. We know how to find, engage, and recruit the right gastroenterology patients, faster.

Gastroenterology FAQs
How many gastroenterology indications does Clariness support?
Clariness supports recruitment across a wide range of gastroenterology indications, including Crohn’s disease, ulcerative colitis, intestinal obstruction, liver failure, cirrhosis, heartburn, irritable bowel syndrome (IBS), non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), functional constipation, celiac disease, and many others.
What are the biggest challenges in gastroenterology clinical trial recruitment?
Many gastroenterology studies recruit patients with episodic conditions, making timing critical. Fluctuating symptoms and inconsistent symptom reporting can make it difficult to identify eligible patients before they move into remission. Clariness combines protocol-specific pre-screening, secondary phone screening within one hour of registration, and targeted digital recruitment to connect patients with study sites while they are still eligible.
How does Clariness improve referral quality for gastroenterology clinical trials?
Diet, lifestyle factors, and variability in symptom reporting can make it difficult to assess patient eligibility accurately. Clariness tailors each pre-screening questionnaire to the study protocol, capturing clinically relevant information early to improve referral quality and reduce site burden.
How does Clariness recruit patients with gastrointestinal conditions that are often undiagnosed or misdiagnosed?
Many gastrointestinal conditions remain undiagnosed or are initially mistaken for other disorders, limiting the pool of eligible participants. Clariness combines condition-specific digital outreach, patient education, and symptom-based pre-screening to identify potential participants and guide suitable patients toward diagnostic confirmation and clinical trial opportunities.
What CRO services for gastroenterology clinical trials does Clariness provide?
Clariness provides end-to-end CRO services for gastroenterology clinical trials, including data-driven feasibility, targeted patient recruitment, protocol-specific pre-screening, patient communications, enrollment success, and site support. By combining these capabilities, we help CROs and sponsors improve referral quality, reduce screen failures, and accelerate enrollment.
