Abstract
Introduction There is a groundswell of interest from patient, industry, and regulatory groups to rigorously and transparently integrate patient-voice into regulatory decision-making. Patient-focused drug development (PFDD) is an approach established by the US Food and Drug Administration to systematically incorporate patient experiences into drug development and evaluation. It has created a demand for scientific advancement to measure and integrate patient-voice into decision-making.Areas covered This narrative review describes the evolving nature of advocacy-regulatory relations preceding PFDD, characterizes current PFDD and other patient-engagement activities, and explores future opportunities for patient participation along the drug development pipeline. We present Duchenne muscular dystrophy as a case study to illustrate how PFDD is being operationalized by patient groups and regulators using both verbal and written data sources.Expert opinion PFDD represents the most widespread approach yet to integrate the patient voice as a source of evidence to inform regulatory decision-making. Regulatory approvals are just one frontier in drug development. On the horizon remain uncertainties in how patient experience can inform post-marketing surveillance, pricing, reimbursement, and health technology assessment. Patient-input may be particularly crucial to demonstrate the value of expensive first-generation rare disease treatments that confer meaningful benefits but do not meet traditional thresholds for cost-effectiveness.
