Patient-Driven Dose Titration with Sanofi's Toujeo Improved Blood Glucose Control Without Increasing Hypoglycemia Risk in Real-Life Clinical Practice

LISBON, Portugal, Sept. 14, 2017 /PRNewswire/ -- A new randomized clinical trial, TAKE CONTROL1, demonstrated better control of blood sugar (HbA1c) without increasing the risk of hypoglycemia in people with type 2 diabetes (T2D) by using Toujeo® (insulin glargine 300 Units/mL, Gla-300) with a simple dose titration regimen ("patient-driven titration") compared with patients whose dose adjustment was managed by their physician ("physician-driven titration").

Participants initiated basal insulin with Toujeo or switched to Toujeo from another basal insulin (including insulin glargine 100 Units/mL, insulin detemir and NPH), while maintaining any previously administer oral antidiabetic drugs (OADs). After 6 months, patients with type 2 diabetes who used patient-driven titration achieved improvement of HbA1c (LS mean difference 0.13%, p=0.0247) compared with those who followed physician-driven titration. The proportion of patients reaching the pre-defined blood glucose target without experiencing severe and/or confirmed hypoglycemia was 67.5% in the patient-driven titration group, compared with 58.4% in the group using physician-driven titration (RR 1.15 [1.02; 1.3], p=0.0187). Similar proportions of patients in both groups (6.4% vs. 6.3%), experienced at least one severe and/or confirmed (<54 mg/dL) hypoglycemic event. Full results will be presented in 2018.

"The results of the TAKE CONTROL study demonstrate that patients can make a critical contribution to work toward their own effective blood sugar target when they are well trained and using a basal insulin such as Toujeo," said Riccardo Perfetti, Vice-President Medical Affairs, DCV Medical Affairs, Sanofi. 

Sanofi is conducting a vast comparative Real-World program in routine clinical practice that covers more than 200,000 patients from U.S. and EU databases. Comparative data in a real-world setting can be relevant for payors and other organizations evaluating how findings from clinical trials can be translated into day-by-day management of diabetes. Two comparative retrospective observational studies, DELIVER 22 and DELIVER 33, have been presented previously. Additional Real-World Evidence is expected to be submitted for publication this year. 

TAKE CONTROL design and study results
TAKE CONTROL is a 24 weeks, open-label, 1:1 ratio randomized, controlled, 2-arm parallel-group, multicenter, multinational study, comparing Gla-300 treatment of people with uncontrolled type 2 diabetes (T2DM), based on a titration algorithm managed by the patient vs Gla-300 treatment based on a titration algorithm managed by the physician. The primary objective was to demonstrate non-inferiority in terms of glycemic control, measured as change from baseline to Week 24 in HbA1c. Patients remained on any previously-taken oral antidiabetic drugs (OADs).

This study included 631 patients with uncontrolled T2DM at screening (62% on basal insulin, 38% insulin-naive), a mean age of 63 years old and a median duration of diabetes of 12 years. The difference in mean HbA1c reduction was -0.13% in favor of patient-driven titration (p<0.0001 for non-inferiority; a subsequent test calculated p=0.0247 for superiority, meeting a requirement of p=0.025). The percentage of patients achieving composite endpoint (defined as a secondary endpoint) of reaching the pre-defined fasting self-measured plasma glucose (SMPG) target of 80-130mg/dL without experiencing severe and/or confirmed hypoglycemia at week 24, was in favor of patient-driven titration group. Overall, at least one episode of hypoglycemia was reported by 36.2% of patients in the patient-driven titration group and by 37.0% of patients in the physician-driven titration group. Severe hypoglycemia was reported in 0.6% of patients in the patient-driven titration group, and 0.3% of patients [0.3%] in the physician-driven titration group.

What is Toujeo® (insulin glargine injection) 300 Units/mL?

Prescription Toujeo® is a long-acting insulin used to control blood sugar in adults with diabetes mellitus.

  • Toujeo® contains 3 times as much insulin in 1 mL as standard insulin (100 Units/mL)
  • Toujeo® is not for use to treat diabetic ketoacidosis
  • Toujeo® should not be used in children

Important Safety Information for Toujeo® (insulin glargine injection) 300 Units/mL

Do not take Toujeo® if you have low blood sugar or if you are allergic to insulin or any of the ingredients in Toujeo®.

Do NOT reuse needles or share insulin pens even if the needle has been changed.

Before starting Toujeo®, tell your doctor about all your medical conditions, including if you have liver or kidney problems, if you are pregnant or planning to become pregnant or if you are breastfeeding or planning to breastfeed.

Heart failure can occur if you are taking insulin together with pills called TZDs (thiazolidinediones), even if you have never had heart failure or other heart problems. If you have heart failure, it may get worse while you take TZDs with Toujeo®. Your treatment with TZDs and Toujeo® may need to be changed or stopped by your doctor if you have new or worsening heart failure. Tell your doctor if you have any new or worsening symptoms including:

  • Shortness of breath
  • Sudden weight gain
  • Swelling of your ankles or feet

Tell your doctor about all the medications you take, including OTC medicines, vitamins, and supplements, and herbal supplements.

Toujeo should be taken at the same time once a day. Test your blood sugar levels daily while using any insulin, including Toujeo®. Do not change your dose or type of insulin without talking to your doctor. Verify you have the correct insulin before each injection. Do NOT use a syringe to remove Toujeo® from your SoloStar® pen. Your dose for Toujeo® may be different from other insulins you have taken. Any change of insulin should be made cautiously and only under medical supervision.

Do NOT dilute or mix Toujeo® with any other insulin or solution. It will not work as intended and you may lose blood sugar control, which could be serious. Use Toujeo® only if the solution is clear and colorless with no particles visible.

While using Toujeo®, do not drive or operate heavy machinery until you know how Toujeo® affects you. Don't drink alcohol or use other medicines that contain alcohol.

The most common side effect of any insulin, including Toujeo®, is low blood sugar (hypoglycemia), which may be serious and can be life-threatening. Severe hypoglycemia may cause harm to your heart or brain. Symptoms of serious low blood sugar may include shaking, sweating, fast heartbeat, and blurred vision.

Toujeo® may cause severe allergic reactions that can lead to death. Get medical help right away if you have:

  • A rash over your whole body
  • Shortness of breath
  • Swelling of your face, tongue, or throat
  • Extreme drowsiness, dizziness, or confusion
  • Trouble breathing
  • Fast heartbeat
  • Sweating

Toujeo® may have additional side effects including swelling, weight gain, low potassium, and injection site reactions which may include change in fat tissue, skin thickening, redness, swelling, and itching.

Toujeo® SoloStar® is a disposable prefilled insulin pen. Talk to your doctor about proper injection technique and follow instructions in the Instruction Leaflet that comes with the pen.
