At Clariness, we work on the premise that no two clinical trials are the same. While others fixate on the quantity of patient referrals, we go to great lengths to understand the target indication, how it impacts the study population and refer only the patients and volunteers that meet our clients’ exacting criteria.

This proven methodology improves patient enrollment and retention rates, which is why we have been entrusted with patient recruitment studies for 13/15 leading pharmaceutical companies, across 7,000+ research centers.

We have supported 1,200+ clinical trials across all major indications

For each individual study we support, we create a detailed targeting approach based on the needs of our partners, various feedback meetings about the study procedure, and the specific patient population of our target indication. This approach has allowed us to successfully support more than 1,200 clinical trials across all major indications, reaching the required number of patients either on time, or ahead of schedule.

On our therapy pages below, you will find a summary of the latest research on patient recruitment within each indication, learn more about our indication-specific experience and expertise, and how we support decentralized clinical trials (DCTs), trial diversity and more.
