Digital Therapeutics (DTx) are increasingly seen as a promising way to provide safe, effective, accessible, sustainable, scalable, and equitable approaches to advance individual and population health. Developing DTx is inherently complex in that DTx may include multiple interacting components, such as tools to support activities like medication adherence, health behavior goal-setting or self-monitoring, and algorithms that adapt the provision of these according to individual needs. As recommended in a recent worldwide review of regulatory approaches for DTx, a way to address this complexity is to base the design, development, testing, and iterative improvements of DTx on real-world evidence (RWE). Notably, that review highlights the need for improved guidance on when and how to use RWE for DTx. In this paper, we propose the DTx RWE Framework to provide a pragmatic, iterative, milestone-driven approach for producing RWE for DTx regulation. The DTx RWE Framework is based on best practices from human-centered design, optimization trials for behavioral interventions, behavioral health research, and implementation science. It maps these onto the traditional four phase development model for pharmaceuticals but includes key adaptations relevant to RWE production for DTx, such as including early and ongoing partnerships between developers of DTx and their intended users in clinical and/or community settings. Adoption of our DTx RWE Framework may help address known problems with current DTx, including questionable marketing claims, lack of evidence-based guidance for patients, providers, and health care leaders and the need to improve economic incentives that advance the adoption and use of DTx.
