About Us

clinical trials, to bring new medicines
and treatments to  patients faster

We close the gap between sponsors,
research sites and patients

Closing the gap between patients and clinical research

The number 1 reason for clinical trial delays and failures is inadequate patient enrollment, in fact it is responsible for delaying 86% of clinical trials worldwide. At Clariness, we believe that digital recruitment and engagement, if done right, can solve this problem, by:

  • Improving the public’s willingness to participate in clinical trials through digital outreach
  • Providing a patient-friendly solution to find, understand and apply for trials
  • Engaging and re-engaging with patients to minimize the likelihood of them dropping out of the study

Why us?

While we are not alone in this mission, our combination of 16+ years of experience and a young, diverse team of experts, is the best option available and that is reflected in the trust of our partners. Our data-driven indication-based marketing and double pre-screener ensure that only patients who qualify are referred to the research centre. This reduces the workload and frustration for sponsors, sites and patients alike.
