Digital Therapeutic Lifestyle Intervention Program for Patients with MASLD

The ENLIGHTEN study that will evaluate the efficacy of a novel DTx lifestyle intervention in participants with non-cirrhotic MASH. People who have MASH, the progressive subtype of MASLD, have the highest risk for liver disease progression and poor outcomes, including cirrhosis and hepatocellular carcinoma, and greater overall mortality. Thus, these participants are expected to experience the greatest benefit from treatment.

This is a randomized, controlled trial comparing DTx lifestyle intervention in participants with non-cirrhotic MASH to standard clinical care. The study includes a screening period (up to 2 wks.) followed by randomization, 52-wk treatment period and 12-wk follow-up period (total duration up to 64 wks.).
