Trial Summary

What is the purpose of this trial?

This study aims to culturally adapt an existing American Diabetes Association (ADA)-recognized diabetes self-management and support or DSMES (Diabetes Self Management Education Support) program (Project Dulce) and integrate an evidence-based text messaging program (Dulce Digital) for implementation in Filipino Americans (FAs) with type 2 diabetes mellitus (T2DM). Cultural adaptations aims to facilitate and enhance patient centered approaches and increase participant engagement by addressing barriers to DSMES unique to FAs, such as linguistic challenges, health literacy and numeracy, cultural beliefs and values, and technology access and use. In addition, this study aims to examine the effectiveness of the culturally and digitally adapted Project Dulce + Dulce Digital in improving diabetes knowledge, belief, attitudes, hemoglobin A1C (glycosylated hemoglobin), and self-management behaviors at baseline to 3 months and 6 months. The unprecedented increase of T2DM prevalence among racial and ethnic minority populations including FAs in recent decades demands for effective strategies to meet the needs in DSMES in this population. The outcomes of the current study will demonstrate that the culturally adapted Project Dulce and integration of Dulce Digital is effective in addressing the needs FAs, an underserved racial and ethnic minority group in high need of culturally appropriate DSMES.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your healthcare provider.

What data supports the effectiveness of the treatment Project Dulce + Dulce Digital for Type 2 Diabetes?

Research shows that Project Dulce, a nurse-managed diabetes program, and Dulce Digital, a text messaging program, both help improve blood sugar control in people with type 2 diabetes, especially in underserved communities. These programs focus on education and self-management, which are key to better diabetes care. ^{1 2 3 4 5}

Is Project Dulce + Dulce Digital safe for humans?

There is no specific safety data available for Project Dulce + Dulce Digital in the provided research articles. ^{4 6 7 8 9}

How is the Project Dulce + Dulce Digital treatment for Type 2 Diabetes different from other treatments?

Project Dulce + Dulce Digital is unique because it combines a nurse-managed diabetes education program with a digital component that uses text messaging to improve health behaviors and glycemic control, particularly targeting underserved populations with cultural barriers to healthcare access. ^{1 2 4 10 11}

Eligibility Criteria

This trial is for Filipino-Americans with type 2 diabetes who can speak English and Tagalog, have an HbA1c level of ≥8%, and are registered or willing to register at a community clinic. It's not for those with severe illnesses, certain liver conditions, low body mass index, pregnancy, recent history of cancer (except some skin cancers), high creatinine levels, recent substance abuse issues, non-permanent residents in the area or current enrollees in Project Dulce.

Inclusion Criteria

Your HbA1c level is higher than 8% within the last month.

I can speak, read, write, and understand both English and Tagalog.

Exclusion Criteria

Your body mass index is less than or equal to 23.

Your liver function tests show that your ALT and AST levels are more than three times higher than the normal range.

History of drug or alcohol abuse within 12 months prior to enrollment

Treatment Details

Interventions

• Project Dulce + Dulce Digital (Behavioral)

Trial Overview The study tests a culturally adapted diabetes self-management program called Project Dulce combined with a text messaging service named Dulce Digital. The goal is to improve diabetes knowledge and self-care among Filipino Americans by addressing cultural barriers. Effectiveness will be measured through changes in beliefs, attitudes towards diabetes management and hemoglobin A1C levels over 3 to 6 months.

Participant Groups

Group I: Project Dulce + Dulce Digital Experimental Treatment 1 Intervention

Patients will participate in a peer-led group diabetes self-management education and support program and receive ongoing support via text messages designed to improve knowledge, health beliefs, self-management behaviors and clinical outcomes.

Findings from Research

In a pilot study involving 18 outpatients with type 2 diabetes, using the 'Calomeal' app for 3 months led to significant reductions in hemoglobin A1c (HbA1c) from 7.9% to 7.6% and body mass index (BMI) from 25.17 kg/m2 to 24.54 kg/m2, indicating improved glycemic control and weight management.

The improvements in HbA1c and BMI were associated with decreased carbohydrate intake as estimated by the app, suggesting that visualizing nutritional intake can enhance self-management in diabetes care.

Participants in Project Dulce, a culturally sensitive diabetes management program for Latinos, showed significant improvements in key health markers after one year, including a reduction in HbA1c from 11.5% to 8.3%, indicating better blood sugar control.

The program also enhanced diabetes knowledge, treatment satisfaction, and reduced inaccurate cultural beliefs, demonstrating that culturally tailored education can lead to better adherence to diabetes care standards and improved health outcomes.

A study analyzing 3,109 serious adverse drug reactions reported to the French pharmacovigilance system found that 83% of pancreatitis cases were associated with incretin-based drugs, indicating a significant risk for patients using these medications.

The analysis revealed a strong association between incretin-based drugs and pancreatitis, with adjusted reporting odds ratios showing a heightened risk for all GLP-1 analogs and DPP-4 inhibitors, suggesting careful monitoring is needed for patients on these treatments.

A total of 7076 individual case safety reports (ICSRs) were analyzed, revealing that 63.6% came from the Middle East, with most reports being nonserious (91.5%) and primarily reported by consumers (70.7%).

Patients in the Middle East were younger (average age 34.2 years) and often used insulin for gestational diabetes, while those in Africa were older (average age 48.1 years) and more likely to have type 2 diabetes, indicating significant regional differences in insulin use and associated adverse events.

The #WeAreNotWaiting movement has led to the development of do-it-yourself artificial pancreas systems (DIYAPS) by motivated individuals in the diabetes community, which integrate continuous glucose monitoring and insulin pumps to improve glycemic control and quality of life for people with type 1 diabetes.

While DIYAPS show promising improvements in diabetes management based on anecdotal evidence and observational studies, their unregulated nature raises safety concerns, and there are significant barriers to acceptance among healthcare professionals and regulatory bodies due to ethical, legal, and funding issues.
