January 22, 2019By: James E. Valentine Download PDF

The traditional model of evaluating treatments based primarily on primary outcome measures has stumbled in its application to rare disease. Rare disease clinical trials face the methodological challenges of small, heterogeneous patient populations and relatively few validated, disease-specific outcome measures. Incorporating qualitative research into rare disease clinical trials may help sponsors, regulators, payers, and prescribers to better understand the real-world and patient-specific impact of a potential therapy. This paper provides a methodologic overview of the use of Patient and Caregiver Perception of Change (PPC and CPC) Assessments utilizing patient and caregiver video interviews to complement the data captured by traditional endpoints in rare disease clinical trials.
