The heart of successful cardiology clinical trials

  • I/E criteria for cardiology studies is complex, combine this with patient comorbidities and you have high SFR
  • Higher levels of patient education required when informing patients of a trial vs. other therapeutic areas
  • A mature therapeutic area with a lot of existing treatments in-market, this impacts trial motivation

Clariness combines 20 years of cardiology therapeutic expertise with data-driven recruitment strategies to overcome these barriers.

Diversity spotlight: Underrepresentation in cardiology research

  • Until 2017, women represented just 3/10 of cardiology trial participants, yet heart-related diseases remain the leading cause of death for women worldwide
  • Black, Hispanic, and Asian participants make up just 17% of cardiology trials worldwide, but account for 50% of patients at risk from cardiological diseases
  • Adults aged 75+ carry 60% of the disease burden, but representing only 32% of participants in Phase II and Phase III trials.

Representation is a necessity for reaching your enrollment goals, and serving the populations who need treatment most.

Cardiology FAQs

Why do cardiology clinical trials have high screen failure rates?

Cardiology clinical trials often experience high screen failure rates due to complex eligibility criteria, multiple comorbidities, and concomitant medications. To improve referral quality, Clariness conducts protocol-specific secondary pre-screening with trained specialists, confirming key I/E criteria in the patient’s local language before site referral.

Cardiology clinical trials often recruit older patients who may have multiple comorbidities, complex medication regimens, and lower digital literacy/engagement, making recruitment more challenging. Clariness addresses these barriers through multilingual secondary pre-screening, patient education, and support through our Enrollment Success Team, and geo-targeted site matching to improve referrals.

Clariness improves retention through patient education and communication materials by our in-house creative services team. Additionally, our Enrollment Success and site support teams provide personalized patient support to keep participants informed, motivated, and engaged throughout the study.

Clariness supports recruitment across a wide range of cardiovascular indications, including atrial fibrillation, cardiovascular disease, hypertension, heart failure/disease, stroke, heart attack, thrombosis, dyslipidemia, hypercholesterolemia, and many others.

Clariness supports faster recruitment with smarter planning – combining data-driven feasibility, targeted outreach, secondary phone screening within 1 hour of online registration, and real-time optimization of campaign and site performance.
