CT-868 for Type 1 Diabetes
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to assess how CT-868, an experimental treatment, affects blood sugar control in adults with Type 1 Diabetes who are overweight or obese. Participants will receive either a low, medium, or high dose of CT-868, or a placebo (a harmless pill resembling the treatment), while maintaining their usual insulin routine. The goal is to determine if CT-868 improves blood sugar management compared to insulin alone. This trial suits adults who have had Type 1 Diabetes for at least a year, have a BMI over 27, and meet specific blood sugar criteria. As a Phase 2 trial, the research focuses on evaluating the treatment's effectiveness in an initial, smaller group of participants.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, you will continue with your standard diabetes care using either an insulin pump or multiple daily injections.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that CT-868 is generally safe for humans. Studies have found that doses between 1.75 and 4.0 mg improve blood sugar levels without causing serious side effects. Most participants experienced only minor issues, if any, which were easy to manage.
One study found that CT-868 helps control blood sugar without significantly affecting glucagon, a hormone that increases blood sugar. This suggests the treatment can effectively help manage diabetes.
Since this trial is in Phase 2, it builds on earlier safety tests. CT-868 has already passed initial safety checks, but researchers continue to gather more information on how different doses work in people.12345Why are researchers excited about this trial's treatments?
Unlike the standard treatments for Type 1 Diabetes, which often involve insulin therapy, CT-868 is an investigational drug that offers a novel approach. Researchers are excited because CT-868 is administered via a subcutaneous injection and targets specific pathways in the immune system, potentially offering a new mechanism of action. This could mean better management of the disease by addressing the underlying immune response rather than just managing blood sugar levels. Additionally, the different dosing options (low, medium, and high) are being explored to optimize effectiveness and minimize side effects, offering a more personalized treatment approach.
What evidence suggests that this trial's treatments could be effective for Type 1 Diabetes?
Research has shown that CT-868 may help people with Type 1 Diabetes better control their blood sugar. In studies with diabetic mice, CT-868 not only aided in weight loss but also improved blood sugar levels compared to liraglutide or a placebo. In humans, doses of CT-868 between 1.75 and 4.0 mg resulted in significant reductions in HbA1c, a measure of long-term blood sugar levels. This trial will test various doses of CT-868, including low, medium, and high doses, alongside a placebo. These findings suggest that CT-868 could effectively lower blood sugar and manage diabetes.12356
