Rare Disease Day 2026: Digital Twins Offer New Hope for Treatment Development

Rare Disease Day on February 28, 2026 highlights the persistent challenges of developing treatments for conditions where patient numbers are small and data is scarce. Confidence in clinical development is driven by evidence, yet rare diseases often lack the depth and scale of data required to support traditional randomized controlled trial models.

AI in clinical development is now moving beyond early hype and into more practical application. Teams are becoming less risk averse and gaining experience using data-driven approaches such as AI-supported protocol optimization, investigator site selection, trial feasibility planning and building regulatory grade real-world datasets to tackle long-standing constraints in rare disease research.

Advances in analytics now make it possible to create digital patient profiles and digital twins for any indication, including rare diseases. While they are not a silver bullet, digital twins offer new avenues of hope where traditional trial designs are impractical, and regulators are increasingly open to alternative forms of evidence.

The CEO and founder of an analytics specialist noted that for many patients, long diagnostic timelines and limited treatment options are a reality. The executive emphasized that while digital twins are not a silver bullet, they offer new avenues of hope where traditional trial designs are impractical, and regulators are increasingly open to alternative forms of evidence.
