This proactive approach minimizes wasted resources and accelerates the progression of promising compounds. Furthermore, AI is enhancing CRISPR-based genome editing by identifying novel editing proteins, predicting off-target effects, and guiding safer therapeutic applications, a critical advancement following the first FDA-approved CRISPR therapy. Companies like Insilico Medicine have already seen their first AI-designed drug enter Phase II clinical trials as of 2024, achieving this milestone in just 18 months—a fraction of the traditional timeline. Initial reactions from the AI research community and industry experts highlight a growing consensus that these AI-driven approaches are not just supplementary but are becoming foundational to modern drug development.
Digital twins, as virtual replicas of physical entities or processes, complement AI by creating sophisticated computational models of biological systems, from individual cells to entire human bodies. These twins are revolutionizing clinical trials, most notably through the creation of synthetic control arms. AI-driven digital twin generators can predict disease progression in a patient, allowing these "digital patients" to serve as control groups. This reduces the need for large placebo arms in trials, cutting costs, accelerating trial durations, and making trials more feasible for rare diseases. Unlearn.AI and Johnson & Johnson (NYSE: JNJ) have partnered to demonstrate that digital twins can reduce control arm sizes by up to 33% in Phase 3 Alzheimer’s trials. Similarly, Phesi showcased in June 2024 how AI-powered digital twins could effectively replace standard-of-care control arms in trials for chronic graft-versus-host disease (cGvHD). In preclinical research, digital twins enable scientists to conduct billions of virtual experiments based on human biology, identifying more promising drug targets and optimizing compounds earlier. As of November 2025, AI-powered digital twins have achieved high accuracy in human lung function forecasting, simulating complex lung physiology parameters and revealing therapeutic effects missed by conventional preclinical testing, further accelerating preclinical drug discovery.
