Pooled analysis: Interventional and observational studies
A post-hoc pooled analysis to evaluate efficacy and safety of insulin glargine 300 U/mL in insulin-naïve people with type 2 diabetes with/ without prior use of glucagon-like peptide-1 receptor agonist therapy.1

Efficacy and safety outcomes of insulin-naïve patients intensifying with Gla-300, with/without prior GLP-1 RA therapy, were evaluated in three analyses (N = 3562): a pooled analysis of seven interventional studies, a subanalysis comparing participants who stopped GLP-1 RA therapy and initiated Gla-300 with those who received add-on Gla-300, and an expanded analysis including two observational studies.1
Pooled analysis of Toujeo® efficacy and safety data from 9 interventional and observational studies in insulin-naïve adults with T2DM with or without prior GLP-1 RA therapy*1
* Pooled data of 9 interventional and observational studies (BRIGHT, EDITION 3, TAKE CONTROL, REACH, REALI [pooled data from 4 European studies], ACHIEVE CONTROL). The 4 studies included from REALI were ITAS, COBALTA, TOUJEO-1 and GOAL_RO (patient-level data were included from these studies). For interventional studies (BRIGHT, EDITION 3, TAKE CONTROL, REACH, ACHIEVE CONTROL, ITAS, COBALTA), included population is defined as all randomized patients. For observational studies (TOUJEO-1, GOAL_RO), included population is defined as all patients having entered the study.1

Sub-analysis of the 512 participants with prior GLP-1 RA from the pooled-analysis, 366 added Toujeo® to ongoing GLP-1 RA (add-on sub-group) and 146 stopped GLP-1 RA when starting Toujeo® (switch sub-group).

†Glycemic outcomes were consistent with outcomes seen in pivotal and key interventional studies.2,3
‡ In those who stopped GLP-1 RA and those who received add-on Toujeo®, 31.9% and 27.0% of participants, respectively, experienced ≥1 hypoglycemic event. Severe hypoglycemia was uncommon at 2.1% and 0.8%, respectively.1
§ Severe hypoglycemia or level 3 hypoglycemia was defined as a severe event characterized by altered mental and/or physical functioning that requires assistance from another person for recovery, irrespective of glucose level.4

TOUJEO® (insulin glargine 300 units/ml) – Abbreviated Prescribing Information
NAME AND PRESENTATION: Toujeo 300 units/ml SoloStar, solution for injection in a prefilled pen. Toujeo 300 units/ml DoubleStar, solution for injection in a pre-filled pen. 1 ml of solution contains 300 units of insulin glargine. Each SoloStar prefilled pen contains 1,5 ml of solution for injection (equivalent to 450 units). Each DoubleStar pen contains 3 ml of solution for injection (equivalent to 900 units). THERAPEUTIC INDICATIONS: Treatment of diabetes mellitus in adults, adolescents and children from the age of 6 years. POSOLOGY AND METHOD OF ADMINISTRATION*: Toujeo is a basal insulin for once-daily administration at any time of the day, preferably at the same time every day. When needed, patients can administer Toujeo up to 3 hours before or after their usually time of administration. The dose regimen (dose and timing) should be adjusted according to individual response. In type 1 diabetes mellitus, Toujeo is to be used once-daily and must be combined with short-/rapid-action insulin to cover mealtime insulin requirements. In patients with type 2 diabetes mellitus, the recommended daily starting dose is 0.2 units/kg. Toujeo can also be given together with other anti-hyperglycaemic medicinal products. Switch: When switching from insulin glargine 100 units/ml to Toujeo, this can be done on a unit-to-unit basis. When switching from a treatment regimen with an intermediate or long-action insulin to a regimen with Toujeo, a change of the dose of the basal insulin may be required and the concomitant anti-hyperglycaemic treatment may need to be adjusted. Close metabolic monitoring is recommended during the switch and in the initial weeks thereafter. For switch details see full SmPC. Special populations: Toujeo can be used in elderly people, renal and hepatic impaired patients and adolescents and children ≥6 years. Renal impairment & hepatic impairment: insulin requirements may be diminished. Elderly: progressive deterioration of a renal function may lead to a steady decrease in insulin requirements. Children: Toujeo can be used in in adolescents and children based on the same principles as adult patients. When switching to Toujeo, dose reduction on basal and bolus insulins needs to be considered on an individual basis to minimize risk of hypoglycaemia. Safety and efficacy in children below 6 years have not been established, no data are available. Method of administration: For subcutaneous use only. Rotate injection sites to reduce the risk of lipodystrophy and cutaneous amyloidosis. Toujeo must not be administered intravenously or in insulin infusion pumps. The Toujeo SoloStar and Toujeo DoubleStar pre-filled pens have been specifically designed for Toujeo and no dose re-calculation is required for either pen. When changing from Toujeo SoloStar to Toujeo DoubleStar, if the patient’s previous dose was an odd number (e.g. 23 units) then the dose must be increased or decreased by 1 unit (e.g. 24 or 22 units). Toujeo DoubleStar prefilled pen is recommended for patients requiring at least 20 units per day. Toujeo must not be drawn from the cartridge of the Toujeo SoloStar pre-filled pen or Toujeo DoubleStar pre-filled pen into a syringe or severe overdose can result. For administration details see full SmPC. CONTRAINDICATIONS: Hypersensitivity to the active substance or to any of the excipients listed in the full SmPC. SPECIAL WARNINGS AND PRECAUTIONS FOR USE*: Record name and batch number of administered product to improve traceability of biological medicinal products. Toujeo is not the insulin of choice for the treatment of diabetic ketoacidosis. Instruct patients to continuously rotate injection site to reduce risk of lipodystrophy and cutaneous amyloidosis; delayed insulin absorption and worsened glycaemic control may occur after injection at affected sites. Sudden change in injection site to unaffected area has resulted in hyperglycaemica; blood glucose monitoring is recommended after changing injection site and dose adjustment of antidiabetic medications may be considered. The prolonged effect of insulin glargine may delay recovery from hypoglycaemia. Insulin glargine 100 units/ml and Toujeo are not bioequivalent and are not interchangeable and switching may result in the need for a change in dose and should only be done under strict medical supervision. Switching patients between other insulins and Toujeo should be done under strict medical supervision and may result in the need for a change in dose. Intercurrent illness requires intensified metabolic monitoring. In rare cases the presence of insulin antibodies may necessitate adjustment of insulin dose. If pioglitazone is used in combination with insulin, especially in patients with risk factors for development of cardiac heart failure, patients should be observed for signs and symptoms of heart failure, weight gain and oedema. Pioglitazone should be discontinued if any deterioration in cardiac symptoms occurs. For further details on special warnings and precautions for use see full SmPC. DRUG INTERACTIONS*: Substances that may enhance or reduce the blood glucose-lowering activity and increase susceptibility to hypoglycaemia are detailed in the full SmPC. PREGNANCY AND LACTATION*: There is no clinical experience with use of Toujeo in pregnant women. For insulin glargine no clinical data on exposed pregnancies from controlled clinical studies are available. A large amount of data on pregnant women indicate no specific adverse effects on pregnancy and no specific malformative nor feto/neonatal toxicity of insulin glargine. The use of Toujeo may be considered during pregnancy if clinically needed. It is unknown whether insulin glargine is excreted in human milk. No metabolic effects on breast-fed newborn/infant are anticipated as insulin glargine is digested into amino acids in the gastrointestinal tract. EFFECTS ON ABILITY TO DRIVE*: Patient’s ability to concentrate and react may be impaired as a result of hypoglycaemia or hyperglycaemia or, for example, as a result of visual impairment. Patients should be advised to take precautions to avoid hypoglycaemia whilst driving. UNDESIRABLE EFFECTS*: Very common: Hypoglycemia. Hypoglycaemia may occur if the insulin dose is too high in relation to the insulin requirement. Common: Lipohypertrophy; injection site reactions. For full list of undesirable effects consult the full SmPC. Clinical study safety data not available for children <6 years. OVERDOSAGE*: Mild episodes of hypoglycaemia can usually be treated with oral carbohydrates. More severe episodes may be treated with intramuscular/subcutaneous glucagon or concentrated intravenous glucose. PHARMACOLOGICAL PROPERTIES: ATC Code: A10A E04.
