This trial was designed to evaluate the effectiveness of the dialogue-based online intervention covivio, which was designed to improve diabetes self-management in patients with type 2 diabetes.
The study aims to test the hypothesis that covivio has a greater positive impact on glycemic control than treatment as usual. Patients with type 2 diabetes mellitus will be randomized and allocated to either an intervention group, receiving covivio in addition to treatment as usual, or a control group, which receives only treatment as usual. The primary endpoint is the HbA1c value six month after baseline.
The aim of this clinical trial is to investigate the effectiveness of the self-guided digital therapeutic covivio in 268 patients with type 2 diabetes mellitus (T2DM). Patients will be randomized and allocated in a 1:1 ratio to either an intervention group, in which they will receive access to covivio in addition to treatment as usual (TAU, n = 134), or to a control group, in which they will receive only TAU (n = 134).
The primary endpoint of this trial will be the between-groups difference of the HbA1c in the intervention and control group at six months adjusted for the baseline HbA1c. In order to show the course of change over time, two timepoints for assessment of effects are planned at four (T1) and six months (T2) after the baseline assessment (T0). The primary endpoint will be the HbA1c at six months post-allocation. Secondary endpoints will be depression, diabetes self-management (DSM), BMI, and quality of life. Figure 1 (section 6.1) summarizes the design of the clinical trial.

| covivio (additional to treatment as usual) | Behavioral | Covivio is a dialogue-based online psychological intervention for patients with type 2 diabetes. This intervention includes elements that address disease literacy, physical activity and exercise, dieting and nutritional principles, coping with depression, etc. Content is adapted to users needs using interactive dialogues, illustrations and audio files. Participants may also continue with their usual treatment. |
