What is the purpose of this trial?

This trial tests a new weekly injection called IcoSema for people with type 2 diabetes to determine if it controls blood sugar better than the daily insulin, insulin glargine. Participants will receive either IcoSema or insulin glargine, aiming to improve blood sugar levels in those whose current oral diabetes medications aren't effective enough. Ideal candidates for this trial have had type 2 diabetes for at least 6 months, struggle with blood sugar control despite taking oral diabetes medications, and have never used long-term insulin. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment.

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop your current medications. However, you must be on stable doses of 1-3 oral diabetes medications for at least 90 days before joining the trial.

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

Research has shown that IcoSema, a new treatment for type 2 diabetes, has been tested in studies involving over 2,600 patients. In these studies, 9% of patients experienced serious side effects, but no deaths were directly linked to the treatment. This indicates that while some serious side effects occurred, they were uncommon.

For insulin glargine, which is already widely used, studies indicate it is generally safe. The risk of major health issues like heart attacks or strokes is low, and most people tolerate it well, with a low chance of serious side effects.

Both treatments have undergone thorough study, and evidence suggests they are generally safe, with only a few serious side effects reported. ^{1 2 3 4 5}

Why are researchers excited about this study treatment for type 2 diabetes?

Most treatments for type 2 diabetes, like standard insulin therapies, require daily injections and primarily focus on managing blood sugar levels. But IcoSema is different because it combines once-weekly dosing with a unique mechanism that integrates both insulin and a GLP-1 receptor agonist. This combination not only simplifies the treatment schedule but also helps improve blood sugar control while potentially offering weight management benefits. Researchers are excited about IcoSema because it could enhance convenience and efficacy for patients compared to the daily insulin injections currently available.

What evidence suggests that this trial's treatments could be effective for type 2 diabetes?

This trial will compare IcoSema with insulin glargine for treating type 2 diabetes. Studies have shown that IcoSema, a once-a-week combination of insulin icodec and semaglutide, better controls blood sugar levels and reduces the risk of low blood sugar compared to other treatments. It also aids in weight loss, a common challenge for people with type 2 diabetes. In contrast, insulin glargine, taken daily, effectively improves blood sugar control and is known for its low risk of causing low blood sugar. Both treatments are effective, but IcoSema offers the convenience of weekly dosing and additional support for weight management. ^{1 2 4 6 7}

Are You a Good Fit for This Trial?

This trial is for people with type 2 diabetes whose blood sugar isn't well-controlled by oral medications. Participants will be randomly chosen to receive either the new weekly medicine IcoSema or daily insulin glargine. The study excludes specific details on eligibility criteria.

Inclusion Criteria

I've been taking 1-3 diabetes pills daily for at least 90 days.

HbA1c ≥ 8.0% (≥ 64.0 millimoles per mole [mmol/mol]) as assessed by central laboratory on the day of screening

Body mass index (BMI) less than or equal to 40.0 kilogram per square meter (kg/m^2)

Exclusion Criteria

I haven't had a heart attack, stroke, or severe heart chest pain in the last 6 months.

My heart failure is severe, limiting my ability to carry out any physical activity without discomfort.

I haven't had diabetic ketoacidosis or taken diabetes/obesity meds not listed in the criteria in the last 90 days.

What Are the Treatments Tested in This Trial?

Interventions

• IcoSema
• Insulin glargine

Trial Overview The effectiveness of a new once-weekly medication, IcoSema (a mix of insulin icodec and semaglutide), is being compared to the daily use of insulin glargine in controlling blood sugar levels over approximately 11 months.

How Is the Trial Designed?

Group I: Insulin glargine Experimental Treatment 1 Intervention

Participants will receive once daily insulin glargine subcutaneously with or without oral anti diabetic drugs for 40 weeks.

Group II: IcoSema Experimental Treatment 1 Intervention

Participants will receive once weekly IcoSema subcutaneously with or without oral anti diabetic drugs for 40 weeks.

Published Research Related to This Trial

In a pilot study of 52 patients with Type 2 diabetes, switching from premixed insulin to insulin glargine combined with oral antidiabetic drugs (OADs) led to significant reductions in HbA1c levels, indicating improved glycaemic control.

The study found no significant differences in hypoglycaemia rates between the treatment groups, suggesting that insulin glargine plus OADs is a safe alternative to premixed insulin for patients with inadequate glycaemic control.

In a pilot study involving 52 patients with Type 2 diabetes poorly controlled on premixed insulin, switching to insulin glargine combined with oral antidiabetic drugs (OADs) significantly improved glycaemic control, as evidenced by a notable decrease in HbA1c levels in both treatment groups (A and B).

The study found no significant differences in hypoglycaemia rates between the treatment groups, indicating that insulin glargine plus OADs is a safe alternative to premixed insulin therapy, with high patient satisfaction leading to a majority opting to continue their assigned treatment.

In a study involving 1,291 patients with type 1 and type 2 diabetes, LY2963016 insulin glargine (LY IGlar) showed similar immunogenicity profiles to Lantus® insulin glargine (IGlar), with low levels of anti-insulin glargine antibodies observed in both groups.

There were no significant differences in clinical outcomes or safety between LY IGlar and IGlar, indicating that both treatments are equally effective and safe for managing diabetes.
