Patient engagement platforms have become central to clinical trials as pharma shifts toward decentralized, hybrid, and AI-enabled study models. In 2026, the focus is not only on patient communication but also on retention, real-time data capture, and operational efficiency at scale.
Industry-wide, clinical trials still face 20–30% patient dropout rates, and decentralized models are shown to reduce attrition by 15–50% depending on indication and design. With global drug development costs averaging $1.3B–$2.6B per approved drug, engagement software directly impacts financial outcomes.
