What is the purpose of this trial?

This trial explores a new three-part treatment for people with type 1 diabetes to determine if it manages blood sugar better than current treatments. It compares the effects of adding dapagliflozin (an oral medication) to a regimen that already includes semaglutide (a weekly injection) and insulin. Participants will receive either the new three-part therapy, a two-part therapy with semaglutide and insulin, or just insulin as usual. Those who have had type 1 diabetes for over a year, regularly check their blood sugar, and use insulin daily might be a good fit for this study. As a Phase 2, Phase 3 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group and represents the final step before FDA approval, offering a chance to contribute to advancing diabetes care.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot have used any diabetes treatment other than insulin in the last 3 months.

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 have used any diabetes treatment other than insulin in the last 3 months.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that semaglutide, one of the treatments in this trial, can lower the risk of major heart problems in people with diabetes. However, its safety and effectiveness for people with type 1 diabetes remain unknown, leaving uncertainty about how well they can tolerate this treatment.

In contrast, dapagliflozin, another treatment in this trial, has been studied more extensively in people with type 1 diabetes. Studies have found it helps control blood sugar and aids in weight loss. However, it also increases the risk of diabetic ketoacidosis (a serious diabetes complication) and other side effects compared to a placebo.

While promising evidence exists for these treatments, it is important to consider both potential benefits and risks. Prospective trial participants should weigh these factors and discuss them with their healthcare provider. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for Type 1 Diabetes because they introduce new combinations and delivery methods that might improve blood sugar control. Unlike the standard of care, which typically involves insulin alone, this approach adds semaglutide, a GLP-1 receptor agonist, and dapagliflozin, an SGLT-2 inhibitor. Semaglutide is administered through a weekly injection and can enhance insulin sensitivity and promote weight loss. Dapagliflozin, taken as a daily pill, helps the body excrete excess glucose through urine. This triple therapy could offer more comprehensive blood sugar management and additional health benefits compared to insulin alone.

What evidence suggests that this trial's treatments could be effective for type 1 diabetes?

Research has shown that semaglutide, which participants in this trial may receive, can help people with type 1 diabetes better control their blood sugar levels. It also aids in weight loss and lowers the risk of heart problems. Dapagliflozin, another treatment option in this trial, has been proven to lower HbA1c levels, a key measure of blood sugar control, and assist with weight loss. However, it might increase the risk of diabetic ketoacidosis (DKA), a serious condition where the body produces too many blood acids. Overall, using semaglutide and dapagliflozin together with insulin, as tested in this trial, has shown promise in improving blood sugar control in type 1 diabetes. ^{2 5 6 7 8}

• Insulin
• Placebo to Dapagliflozin
• Semaglutide

Trial Overview

The trial is testing if adding dapagliflozin to semaglutide and insulin (triple therapy) better controls blood sugar in Type 1 Diabetes than just semaglutide and insulin (dual therapy) or insulin alone. Participants will receive one of these combinations to compare effectiveness.

How Is the Trial Designed?

Group I: Triple therapy Experimental Treatment 3 Interventions

Once a day oral pill (green, plain, diamond shaped film coated 5 mg tablet) of Dapagliflozin (an SGLT-2 inhibitor) added to once a week injection of semaglutide and standard of care insulin in the second 6 months of 1/2 of the dual therapy arm (1/3 of total patients (38 patients)). Dapagliflozin will be started at 5 mg for one week, and then increased to 10 mg for the remainder of the study

Group II: Dual Therapy Experimental Treatment 2 Interventions

Once a week injection of Semaglutide (a GLP-1 receptor agonist) in addition to standard of care insulin for the first six months in 2/3 of patients (76 patients). Semaglutide is a clear, colorless solution that contains 2 mg of semaglutide in a 1.5 mL (1.34 mg/mL) pre-filled, disposable, single-patient-use pen injector. Semaglutide will be started at the 0.25 mg dose for the first two weeks, then increased to 0.5 mg at week 2, and then yet again increased to 1.0 mg at week 4.

Group III: Control Active Control 1 Intervention

Standard of care insulin will be used as an active comparator arm for 1/3 of patients (38 patients) for the entire duration of the study.

Group IV: Triple therapy control Placebo Group 3 Interventions

Once a day oral pill (green, plain, diamond shaped film coated 5 mg tablet) of the Placebo form of Dapagliflozin added to once a week injection of semaglutide and standard of care insulin in the second 6 months of 1/2 of the dual therapy arm (1/3 of total patients (38 patients)).

Humalog, evaluated in 2834 patients across eight international studies, showed significant improvements in postprandial glycaemic control and a reduction in hypoglycaemic episodes, particularly at night, despite no significant decrease in overall HbA1C levels.

In a crossover study, patients using Humalog experienced five times fewer severe hypoglycaemic episodes compared to those on standard treatment, indicating its potential for safer diabetes management, although intensive treatment with multiple injections is recommended for optimal results.

In a study of 951 severely insulin-resistant type 2 diabetes patients, initiating Humulin R U-500 (U-500R) significantly improved treatment compliance and glycemic control, as evidenced by a reduction in HbA1c from 9.3% to 8.5%.

While U-500R improved overall insulin dosage and patient adherence, there was a modest increase in hypoglycemic events, highlighting the need for careful monitoring during treatment.
