Clinical Trial Summary

The VICTOR study plans to include rural communities served by Colorado Heart Healthy Solutions (CHHS) program and find out whether participants will accept a referral to a comprehensive virtual lifestyle intervention, Virta Health. The Virta Health program induces nutritional ketosis to improve glucose control in individuals with type 2 diabetes. The study will inform the acceptability of the referral, the retention of participants in lifestyle intervention, and the durability of effects on glucose control after the lifestyle intervention has ended.


Description:

In rural communities served by Colorado Heart Healthy Solutions (CHHS), referral to a comprehensive remotely-delivered (virtual) continuous remote care to induce nutritional ketosis combined with remote medication management will improve glycemic control in patients with type 2 diabetes as compared with standard care. The study intervention is the referral. Subjects are not mandated to receive Virta treatment and are welcome to continue in the study whether or not the referral is accepted. 2 rural communities served by CHHS have been chosen as recruitment sites. Study patients will be randomized at the site level. Objectives Primary: To assess glycemic control in patients with type 2 diabetes living in a rural community referred to a comprehensive remotely-delivered continuous remote care to induce nutritional ketosis combined with remote medication management (termed "continuous remote care") as compared with those living in a rural community offered standard care. Secondary: 1. To assess the effects of referral to continuous remote care as compared with standard care on body weight and on body mass index 2. To assess the effects of referral to continuous remote care as compared with standard care on number and doses of anti-hyperglycemic medications 3. To determine the durability of a continuous remote care intervention when paired with ongoing community health worker support Exploratory: 4. To assess the effects of referral to continuous remote care as compared with standard care on LDL-cholesterol, fasting glucose, and fasting triglyceride/HDL-cholesterol ratio 5. To assess patient-reported outcomes of continuous remote care as compared with standard care 6. To determine enrollment rate (offered vs accepted) in patients with type 2 diabetes living in rural communities referred to continuous remote care. 7. To determine active engagement (number, timing, and types of 2-way contacts) and retention in patients with type 2 diabetes living in rural communities referred to continuous remote care.
