Introduction: Prescription digital therapeutics (PDTs) represent a new class of software-based medical devices authorized by the Food and Drug Administration (FDA) to treat disease Somrystâ˘, the first PDT for treating chronic insomnia, delivers cognitive behavioral therapy for insomnia (CBT-I) via a mobile application CBT-I is the guideline-recommended, first-line treatment for chronic insomnia, but availability of CBT-I therapists is limited Somryst addresses this need by providing asynchronous access to CBT-I treatment As a contactless therapeutic medium, Somryst is also an ideal option when face-to-face therapy is not available or recommended for safety reasons (e g because of possible exposure to the SARS-CoV-2 virus) Areas covered: This review summarizes the mechanisms of action and technical features of Somryst, and describes safety and effectiveness data from the randomized trials on which FDA clearance was based Expert opinion: Somryst demonstrates robust clinical efficacy with a favorable benefit-to-risk profile for treating adults with chronic insomnia FDA clearance was based on data from 2 clinical trials of the first-generation web-based CBT-I platform Sleep Healthy Using the Internet (SHUTi) Somryst, and PDTs in general, are promising devices to address the need for greater accessibility to effective therapies

Introduction: Prescription digital therapeutics (PDTs) represent a new class of software-based medical devices authorized by the Food and Drug Administration (FDA) to treat disease. Somryst™, the first PDT authorized by FDA for treating chronic insomnia, delivers cognitive behavioral therapy for insomnia (CBT-I) via a mobile application. CBT-I is the guideline-recommended, first-line treatment for chronic insomnia, but availability of CBT-I therapists is limited. Somryst addresses this need by providing asynchronous access to CBT-I treatment. As a contactless therapeutic medium, Somryst is also an ideal option when face-to-face therapy is not available or recommended for safety reasons (e.g., because of possible exposure to pathogens such as SARS-CoV-2 virus). Areas covered: PDTs are the first class of software-based medical devices FDA-cleared and available via mobile applications. This review summarizes the mechanisms of action and technical features of Somryst, and describes safety and effectiveness data from the randomized trials on which FDA clearance was based. Expert opinion: Somryst demonstrates robust clinical efficacy with a favorable benefit-to-risk profile for treating adults with chronic insomnia. FDA clearance was based on data from 2 clinical trials of the first-generation web-based CBT-I platform Sleep Healthy Using the Internet (SHUTi). Somryst, and PDTs in general, are promising devices to address the need for greater accessibility to effective therapies.
