Respiratory intro

Helping respiratory trial recruitment breathe easier

Respiratory disease affects nearly 570 million people worldwide, but the patients these trials need most, are only reliably identifiable in narrow, unpredictable windows. 

  • Asthma – Exacerbations nearly double in autumn vs summer, fluctuating when patients meet criteria 
  • COPD – Only 2.3% of real-world patients meet all standard trial I/E criteria at any one time 
  • Cystic fibrosis – Investigational vs. approved treatments vary by country, in the US >90% of patients currently use CFTR therapy, others just 1.8% 

Clariness combines 20 years of respiratory expertise with recruitment strategies built to find rare, progressive-disease patients earlier, before misdiagnosis and delays push them further from your study’s I/E eligibility.

Respiratory FAQs

What are the biggest recruitment challenges in respiratory clinical trials?

Respiratory clinical trials often involve patients with fluctuating symptoms, complex treatment histories, and strict I/E criteria based on disease severity, exacerbation history, and prior medications. Overlapping studies and seasonal triggers can further complicate recruitment. Clariness addresses these challenges through protocol-specific recruitment strategies, two-step screening, and continuous campaign optimization to improve referral quality. 

Many respiratory conditions, including asthma, COPD, and seasonal allergies, are influenced by environmental triggers such as pollen, viral infections, weather, and air quality. Clariness adapts recruitment strategies throughout the year, optimizing campaign timing, messaging, and channel selection to align with seasonal disease patterns and maximize patient engagement. 

Clariness has supported a wide range of respiratory indications in over 130+ global studies, including asthma, COPD, and Chronic cough. 

Multiple respiratory studies frequently recruit similar patient populations at the same time, creating competition for eligible participants. Clariness develops tailored recruitment pathways and protocol-specific screening to help direct patients to the most appropriate study while supporting recruitment across multiple protocols. 

Many people living with respiratory conditions actively seek information online about symptom management and treatment options. Clariness combines targeted digital outreach, social media advertising, and protocol-specific pre-screening to engage potential participants, educate them about clinical research, and identify those who may be eligible for referral.
