Trial Summary

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking medications that affect glucose metabolism, like steroids or metformin. It's best to discuss your current medications with the trial team.

How is the drug DFMO unique for treating type 1 diabetes?

DFMO (also known as Eflornithine) is unique because it is being explored as a potential treatment for type 1 diabetes, a condition that primarily relies on insulin therapy. Unlike traditional treatments, DFMO may offer a novel approach by targeting different pathways, although its exact mechanism in type 1 diabetes is still under investigation.12345

What is the purpose of this trial?

The goal of this clinical trial is to test a drug known as DFMO in people with Type 1 Diabetes (T1D). The main question\[s\] it aims to answer are:* Does it reduce stress on the cells that make insulin?* Does it preserve what is left of the body's insulin production? Participants will take either DFMO or a placebo (looks like DFMO but has no active ingredients) two times a day for about 6 months. Participants will have 6 in person visits and 1 phone visit over a period of 12 months. Visits will include blood draws urine collection and other tests.

Eligibility Criteria

The TADPOL trial is for people aged 6-40 with recent Type 1 Diabetes diagnosis, who still produce some insulin and have not used immunomodulatory drugs. They must have normal hearing, no psychiatric disorders affecting participation, and agree to use birth control if applicable. Excluded are those with conditions or medications influencing glucose metabolism, active seizure disorders, difficulty swallowing pills, certain blood or kidney issues.

Inclusion Criteria

Your hearing test results must show that you can hear quiet sounds at different pitches.
I am between 6 and 40 years old and have been diagnosed with Type 1 Diabetes.
I have not received any immune system modifying treatments.

Interventions

  • DFMO
  • Placebo
Trial Overview This study tests DFMO's ability to reduce stress on insulin-producing cells and preserve insulin production in Type 1 Diabetes patients over a period of about six months. Participants will be randomly assigned to take either DFMO or a placebo twice daily and will undergo various tests including blood draws during their visits.

Findings from Research

Sotagliflozin effectively lowers HbA1c levels in patients with type 1 diabetes mellitus (T1DM) without significantly increasing the risk of hypoglycemia, making it a promising option for better glycemic control.
However, the risk of diabetic ketoacidosis is notably higher with sotagliflozin, which means it should only be used in carefully selected patients who are well-informed and closely monitored by their healthcare provider.

In a study of 100 patients with type-1 diabetes and poor glycaemic control, metformin treatment for one year did not significantly improve HbA1c levels compared to placebo, indicating no enhancement in glycaemic control.
However, metformin was associated with a significant reduction in total daily insulin doses and body weight, suggesting potential benefits in insulin management and weight control for patients with type-1 diabetes.

Treatment with AG490 in prediabetic NOD mice significantly delayed the onset of diabetes compared to control mice, indicating its potential efficacy in preventing Type 1 Diabetes (T1D).
AG490 not only enhanced regulatory T-cell functions and reduced blood glucose levels but also influenced the expression of PPARฮณ, suggesting that targeting the Jak-Stat signaling pathway could have both immunological and metabolic benefits in T1D prevention.
