About

This clinical trial aims to find out if a digital behavioral program, delivered through the SIPPA digital therapeutics app, can help improve blood sugar control and lower the risk of liver fibrosis in adults with type 2 diabetes who are at low to moderate risk for liver disease.

Main Research Question:

Can adding the SIPPA behavioral program to standard diabetes care lower HbA1c (a marker of blood sugar control) more than standard care alone?

Study Design:

The study has two groups (called "arms") for comparison:

Arm 1: Control Group Subgroup 1.1: Participants receiving standard care without GLP-1 medication. Subgroup 1.2: Participants receiving standard care with GLP-1 medication.

Arm 2: Intervention Group Subgroup 2.1: Participants receiving standard care without GLP-1 medication, plus the SIPPA behavioral program.

Subgroup 2.2: Participants receiving standard care with GLP-1 medication, plus the SIPPA behavioral program.

Researchers will compare outcomes across the matched groups in each arm to evaluate the impact of the SIPPA program.

What Participants Will Do:

All participants will have lab tests at the start of the study, at 3 months, and at 6 months. These tests include:

• HbA1c (a measure of average blood sugar levels),
• Fib-4 score (used to estimate liver fibrosis risk), and
• Liver enzyme tests.

Participants in the intervention group (Arm 2) will also:

• Use the SIPPA app daily to complete behavioral modules, track blood sugar
• levels, and log health behaviors (like diet and activity).
• Have weekly check-ins with a health navigator to support progress and stay on track with their diabetes treatment plan.

Full description

Study Purpose and Objectives This study is designed to evaluate whether a smartphone-based behavioral intervention, called SIPPA Health, can enhance the effects of standard diabetes care-including for patients who are prescribed GLP-1 receptor agonists (a common injectable diabetes medication). SIPPA Health, guided by behavioral predictive analytics, delivers daily lifestyle coaching through an app, including exercise goals, meal logging, glucose tracking, and weekly remote check-ins with a trained health navigator.

The study will examine whether adding SIPPA to standard treatment improves blood sugar control, reduces liver fibrosis risk, supports weight management, and helps personalize diabetes care through digital tools. Specific objectives include:

Glycemic Control: Measure changes in hemoglobin A1c (HbA1c)-a long-term blood sugar marker between those who use the SIPPA app and those who receive standard care alone.

Liver Health: Measure Fibrosis-4 (Fib-4) index, an estimate of liver scarring, between those who use the SIPPA app and those who receive standard care alone.

Population-level Diabetes Risk Indicator: Assess whether there is a difference in the distributions between SIPPA users and patients receiving only standard care service; where the distribution will consider BMI change, A1c progression, glucose variability (time-in-range), and engagement with self-care activities.

AI Risk Stratification (Pilot): Test a machine learning model that classifies participants by clinical, behavioral, and social determinants of health data. The aim is to inform future personalized care plans.

Study Design

This is a randomized, controlled pilot trial lasting six months, involving 200 adult participants with either type 2 diabetes or prediabetes (defined as two consecutive HbA1c values between 5.8% and 6.5%). All participants receive standard diabetes care and are randomly assigned to one of two main groups:

ARM 1 (Control Group): Standard care alone. ARM 2 (Intervention Group): Standard care plus the SIPPA Health app.

Each group is further divided based on whether the participant is currently using a GLP-1 receptor agonist:

Subgroup G1: No GLP-1 therapy. Subgroup G2: On GLP-1 therapy.

This results in two study arms with four subgroups for the purpose of comparative study:

Control without GLP-1 (ARM 1-G1) Control with GLP-1 (ARM 1-G2) SIPPA without GLP-1 (ARM 2-G1) SIPPA with GLP-1 (ARM 2-G2)

All participants complete the same laboratory and survey assessments at baseline, 3 months, and 6 months. These include blood tests (A1c, liver enzymes, lipids), weight, and self-reported lifestyle data. SIPPA users also receive a smartphone app with daily reminders, educational content, and weekly coaching calls to support their self-care routines.

Outcome Measures Primary Clinical Outcome (6 Months) Change in HbA1c (%): The main measure of long-term blood glucose control.

Secondary Outcomes Fibrosis-4 (Fib-4) Index: A validated liver fibrosis score calculated from age, AST (aspartate aminotransferase), ALT (alanine aminotransferase), and platelet count.

Weight and Body Mass Index (BMI): Measured in pounds and kilograms per square meter.

Time-in-Range (%): The percentage of glucose readings within the healthy range (70-180 mg/dL), assessed by continuous glucose monitor (CGM) or glucose logbooks.

Composite Diabetes Risk Indicator (DRI): A novel index that integrates change in A1c, glucose variability, and adherence to self-care behaviors (e.g., step counts, app engagement). Participants are categorized into low, medium, or high risk for diabetes-related complications.

Exploratory Outcomes App Engagement: For SIPPA users, the study will track number of logins, modules completed, step counts, and minutes spent in coaching calls.

Subgroup Effectiveness: Analysis to identify which population groups (e.g., based on baseline self-efficacy or social factors) benefit most from SIPPA.

Safety and Tolerability: Adverse events, hypoglycemia, or any app-related issues will be monitored continuously. Data are reviewed by a safety board and institutional review body.
