Participants with Major Depressive Disorder (MDD) or Generalized Anxiety Disorder (GAD) will use a prescribed digital therapeutic for 8-10 weeks, and will complete depression and anxiety measures during this time. After the treatment period, participants will be followed monthly for 12 months.

This study aims to assess the safety and efficacy of HPDT-DA-013 digital therapeutic in adults ages 22 years and older with MDD or GAD. Participants access HPDT-DA-013 on their smart device or computer and complete treatment over a period of 8-10 weeks. During the treatment period, participants complete PHQ-9 and GAD-7 assessments, as well as safety and medication use questionnaires. After 8-10 weeks, participants will complete end-of-treatment assessments, and access to HPDT-DA-013 will be removed. Participants are then followed for a period of 12 months.
