Key Challenges

 Recruitment Delays Due to Narrow Eligibility Criteria

Many respiratory trials require strict lung-function parameters, biomarker validation, or phenotype-specific enrollment, creating challenges in identifying suitable participants. High screen-failure rates in COPD, asthma, and sleep apnea studies slow recruitment timelines. Patients with multiple comorbidities or inconsistent inhaler adherence often fail protocol requirements, further limiting cohort size. These constraints place pressure on sponsors and CROs to expand multi-site networks, incorporate digital pre-screening tools, and adopt adaptive recruitment strategies to meet enrollment targets without compromising data integrity.

 High Participant Burden and Retention Issues

Respiratory trials often involve frequent spirometry tests, polysomnography assessments, inhaler technique evaluations, and prolonged monitoring periods, resulting in high participant burden. Travel requirements, complex dosing protocols, and device-handling expectations contribute to dropout risks, especially among elderly and chronic respiratory patients. Retention becomes challenging in long-duration trials where symptom fluctuations and comorbidities impact patient engagement. Sponsors increasingly rely on hybrid trial models, home-based assessments, and remote monitoring devices to enhance retention while reducing physical and logistical burdens on participants.
