What You Need to Know Before You Apply

What is the purpose of this trial?

The goal of this study is to quantify day-to-day changes in blood glucose during treatment towards remission in ketosis-prone diabetes (KPDM) and describe them using a mathematical model of KPDM pathogenesis and remission.

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's best to discuss this with the trial coordinators or your doctor.

Is insulin safe for use in humans?

Research shows that various types of insulin, including insulin lispro and insulin detemir, have safety profiles comparable to regular human insulin. Studies have not found significant differences in adverse events or complications, indicating that these insulins are generally safe for use in humans. ^{1 2 3 4 5}

How does the drug insulin differ from other treatments for ketosis-prone diabetes?

Insulin therapy for ketosis-prone diabetes is unique because it uses continuous glucose monitoring and a combination of fast-acting and long-acting insulin analogues to closely mimic natural insulin secretion, improving blood sugar control and reducing the risk of hypoglycemia (low blood sugar) compared to traditional insulin treatments. ^{6 7 8 9 10}

What data supports the effectiveness of the drug Insulin, including Humulin R, Novolin R, and others, for treating ketosis-prone diabetes?

Research shows that insulin detemir (Levemir) is effective in maintaining blood sugar control with less risk of low blood sugar at night and less weight gain compared to other insulins. Additionally, insulin lispro (Humalog) and regular human insulin (Humulin R) have been studied for their effects on liver glucose production in type 1 diabetes, which is relevant for managing blood sugar levels. ^{1 11 12 13 14}

Insulin detemir (Levemir) offers a long-acting and consistent insulin option for patients with type 1 or type 2 diabetes, providing a predictable effect with less variability in blood sugar control compared to NPH insulin.

It is at least as effective as NPH in managing overall blood sugar levels while reducing the risk of nocturnal hypoglycemia and causing less weight gain, making it a favorable choice for basal insulin therapy.

In a study involving 10 type 1 diabetes patients, insulin lispro (Humalog) was found to enhance the liver's response to glucagon, leading to a greater increase in hepatic glucose production compared to regular human insulin (Humulin R).

This increased sensitivity to glucagon with insulin lispro may help reduce the risk of severe hypoglycemia in type 1 diabetes patients undergoing intensive insulin therapy.

In a study of 221 adults with type 1 diabetes, switching to ultra-long-acting insulin (degludec U100 and glargine U300) did not significantly change the incidence of diabetic ketoacidosis (DKA) episodes, indicating that this new insulin type may not reduce DKA risk.

Despite higher total daily insulin doses after switching to ultra-long-acting insulin, there was no significant change in glycated hemoglobin A1C (HbA1c) levels, suggesting that insulin type and dosage alone may not be sufficient to control diabetes effectively.

In a study involving 112 children and adolescents with type 1 diabetes, the combination of ultrashort acting insulin aspart with detemir or glargine showed a significant decrease in HbA1c levels, indicating improved blood sugar control over 12 and 24 weeks.

The use of detemir and glargine significantly reduced the risk of hypoglycemia compared to traditional NPH-insulin, while maintaining a stable body mass index in the detemir group, suggesting a safer and more effective treatment option.

Basal insulin is crucial for regulating glucose and fatty acid release, and in type 1 diabetes, traditional long-acting insulins like NPH are inadequate due to their peak effects, which can lead to hypoglycemia and hyperglycemia.

Continuous subcutaneous insulin infusion (CSII) and long-acting insulin analogs like glargine and detemir are recommended for better management of basal insulin in type 1 diabetes, as they provide a more stable insulin release, reducing the risk of hypoglycemia and improving blood glucose control.

In a pilot study involving 19 adults using the MiniMed™ 670G system, both Novolog® and Fiasp® insulin showed similar effectiveness in managing blood sugar levels, with no significant differences in time spent within the target glucose range or hypoglycemia rates.

Fiasp® required a slightly higher daily insulin dose compared to Novolog®, but both insulins resulted in comparable glycemic outcomes, indicating that either can be effectively used in a hybrid closed-loop system.

A comprehensive review of 50 studies over the past 20 years revealed significant differences in bioactivity between human insulin and various insulin analogues, affecting metabolism, cell growth, and other cellular functions.

The clinical implications of these differences in bioactivity are still unclear and require further investigation to understand their impact on different patient populations.

A comparison of insulin lispro and regular human insulin (Humulin R) in 3634 patients with type 1 and type 2 diabetes showed no significant differences in treatment-emergent adverse events, indicating similar safety profiles for both insulins.

Both insulin therapies did not differ in their effects on the progression of chronic diabetes complications, such as retinopathy, neuropathy, cardiovascular disease, or kidney disease, suggesting that insulin lispro is as safe as Humulin R.

In a 32-week study involving 686 patients with Type 2 diabetes, insulin detemir (IDet) therapy was found to be safe, with no serious adverse drug reactions reported and a significant reduction in total hypoglycemic events from 435 to 204.

Patients experienced improved glycemic control, as indicated by a decrease in glycated hemoglobin A1c from 9.9% to 7.7% and fasting plasma glucose from 11.9 mmol/L to 7.4 mmol/L, alongside a slight reduction in body weight.

In a study involving 28 critical care patients, Humalog insulin (Hlog) demonstrated a significantly less profound carryover effect and shorter duration of action compared to Humulin insulin (Hlin), indicating it may lead to more stable blood glucose levels after treatment ends.

Hlog also resulted in a faster drop in blood glucose during infusion and a quicker rise after discontinuation, suggesting it could be a more effective option for insulin infusion therapy in critically ill patients.

The focus of insulin therapy has shifted from merely providing insulin to mimicking natural insulin secretion, which is crucial for preventing long-term complications of diabetes; this includes using fast-acting and long-acting insulin analogues to better control blood glucose levels.

Advancements in technology, such as continuous insulin pumps and glucose sensors, are improving blood glucose stability and may lead to semi-automated insulin delivery systems, enhancing the management of diabetes beyond traditional methods.

Insulin remains the primary treatment for type 1 diabetes, but recent advancements in insulin analogues have significantly improved glycemic control and allowed for more physiological basal/bolus insulin regimens.

New basal insulin analogues, such as degludec, pegylated lispro, and glargine U300, have shown improvements in duration of action and reduced risk of hypoglycemia, addressing key challenges in intensive diabetes management.

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.

Short-acting insulin analogues like lispro, aspart, and glulisine provide faster action and better post-meal blood sugar control without increasing the risk of hypoglycemia, allowing for administration just before meals.

Long-acting insulin analogues such as glargine and detemir offer stable insulin levels for up to 24 hours with a lower risk of nighttime hypoglycemia, improving overall blood glucose management in diabetic patients.
