Proven performance in randomising patients for trials

Having randomised thousands of patients across various indications, Clariness knows how to deliver and has the data and experience to prove it. Recent patient recruitment highlights include:

  • More than 300 patients randomised for a tinnitus study, which took place at 180 sites in 11 countries over 15 months
  • A 32% randomised referral conversion rate in a dementia study at a decentralised trial site in Germany over the course of nine months
  • A 27% randomised contribution in an atopic dermatitis drug study, which was carried out at 15 sites in three countries over four months
  • A 54% randomised contribution in a nine-month non-alcoholic fatty liver disease study held at four sites in two countries

Patient insights to improve efficiency in clinical trials

Studies leveraging patient insights recruit 30% more patients, which is why Clariness focuses on delivering insights that fuel study design and significantly boost patient enrolment and retention. We gather insights directly from patients and healthcare professionals (HCPs) to answer the questions your study team should be asking, such as:

  • What is the trade-off between inclusion and exclusion requirements and patients’ willingness to participate?
  • How does the trial’s target population vary by country, ethnicity and other factors?
  • Do the chosen sites have the right patients, technology and staff to support the study?

For these and other questions, we align insights to our clients’ focus areas to ensure we provide actionable data.

Clariness’ services allow you to identify your largest enrolment barriers, select the most appropriate sites and countries for trials, make use of the benefits of decentralised clinical trials, and avoid expensive protocol amendments by understanding which study procedures are truly needed.

Study creatives to improve patient enrolment and retention

Clariness helps clinical trial sponsors unlock the full potential of their sites by providing study materials designed with data and patient input that maximise enrolment and retention. These can give trials an identity that boosts recall and referrals, as well as drive patient enrolment and improve conversions.

Through 18 years of experience and performance data, spanning more than 100 indications with randomisations in more than 50 countries, we can deliver patients and insights aligned to your focus area.
