Rare Disease, Rare Opportunity: How PXO Unlocks Enrollment And Equity In Ultra-Orphan Trials

Rare disease clinical trials face unique operational and ethical complexities that standard recruitment models fail to address. Contrary to the assumption that smaller patient populations equate to simpler studies, rare disease trials are among the most fragile in clinical development. These trials face challenges such as diagnostic delays, narrow eligibility, and high screen failure rates that are compounded by the emotional and logistical burden on patients and caregivers.

Jumo Health’s Patient Experience Optimization (PXO) model offers a transformative framework that reframes rare disease trials from transactional recruitment exercises into inclusive, behaviorally intelligent ecosystems. PXO integrates five critical layers—Trust Architecture, High-Context Clarity, Caregiver Integration, Decentralized Support Infrastructure, and Continuity-Driven Retention Systems—to align study operations with the lived realities of rare disease communities. By co-creating content with advocates, contextualizing trial information, and providing decentralized, caregiver-inclusive support, PXO fosters informed, emotionally prepared participation and sustained retention.

PXO-driven trials demonstrate marked improvements in enrollment intent, consent quality, retention, and data equity. By anchoring clinical operations in empathy and behavioral science, PXO not only enhances operational efficiency but also rebuilds trust with a patient population that is discerning, not desperate. In rare disease research, respect is not a luxury—it is a necessity for success.
