Overview

This is a summary of the European public assessment report (EPAR) for Tesavel. It explains how the Committee for Medicinal Products for Human Use (CHMP) assessed the medicine to reach its opinion in favour of granting a marketing authorisation and its recommendations on the conditions of use for Tesavel.

Tesavel is a medicine that contains the active substance sitagliptin. It is available as tablets (25, 50 and 100 mg).

Tesavel is used in patients with type-2 diabetes to improve the control of blood glucose (sugar) levels. It is used in addition to diet and exercise in the following ways:

  • on its own, in patients who are not satisfactorily controlled on diet and exercise and in whom metformin (an antidiabetes medicine) is not suitable;
  • in combination with metformin or a PPAR-gamma agonist (a type of antidiabetes medicine) such as a thiazolidinedione, in patients who are not satisfactorily controlled on metformin or the PPAR-gamma agonist used on its own;
  • in combination with a sulphonylurea (another type of antidiabetes medicine) in patients who are not satisfactorily controlled with a sulphonylurea used on its own and in whom metformin is not suitable;
  • in combination with both metformin and a sulphonylurea or a PPAR-gamma agonist, in patients who are not satisfactorily controlled on the two medicines;
  • in combination with insulin, with or without metformin, in patients who are not satisfactorily controlled on a stable dose of insulin.

The medicine can only be obtained with a prescription.

Tesavel is taken at a dose of 100 mg once a day. If Tesavel is taken with a sulphonylurea or insulin, the dose of the sulphonylurea or insulin may need to be lowered to reduce the risk of hypoglycaemia (low blood sugar levels).

In patients with moderately or severely reduced kidney function the dose of Tesavel should be reduced.

Type-2 diabetes is a disease in which the pancreas does not make enough insulin to control the level of glucose in the blood or when the body is unable to use insulin effectively. The active substance in Tesavel, sitagliptin, is a dipeptidyl-peptidase-4 (DPP-4) inhibitor. It works by blocking the breakdown of ‘incretin’ hormones in the body. These hormones are released after a meal and stimulate the pancreas to produce insulin. By increasing levels of incretin hormones in the blood, sitagliptin stimulates the pancreas to produce more insulin when blood glucose levels are high. Sitagliptin does not work when the blood glucose is low. Sitagliptin also reduces the amount of glucose made by the liver, by increasing insulin levels and decreasing the levels of the hormone glucagon. Together, these processes reduce blood glucose levels and help to control type-2 diabetes.

Tesavel was studied in nine studies involving almost 6,000 patients with type-2 diabetes whose blood glucose levels were not adequately controlled:

  • four of the studies compared Tesavel with placebo (a dummy treatment). Tesavel or placebo were used on their own in two studies involving 1,262 patients, as an add-on to metformin in one study involving 701 patients, and as an add-on to pioglitazone (a PPAR-gamma agonist) in one study involving 353 patients;
  • two studies compared Tesavel with other antidiabetes medicines. One study compared Tesavel with glipizide (a sulphonylurea), when they were used as an add-on to metformin in 1,172 patients. The other study compared Tesavel with metformin, used on their own, in 1,058 patients;
  • three additional studies compared Tesavel with placebo when they were added to other antidiabetes medicines: glimepiride (another sulphonylurea), with or without metformin, in 441 patients; the combination of metformin and rosiglitazone (a PPAR-gamma agonist) in 278 patients; and a stable dose of insulin, with or without metformin, in 641 patients.

In all of the studies, the main measure of effectiveness was the change in the level of a substance in the blood called glycosylated haemoglobin (HbA1c), which gives an indication of how well the blood glucose is controlled.

Tesavel was more effective than placebo when it was taken alone or in combination with other antidiabetes medicines. In patients taking Tesavel on its own, HbA1c levels fell from around 8.0% at the start of the studies by 0.48% after 18 weeks and 0.61% after 24 weeks. In contrast, they rose by 0.12% and 0.18%, respectively, in the patients taking placebo. Adding Tesavel to metformin reduced HbA1c levels by 0.67% after 24 weeks, compared with a fall of 0.02% in the patients adding placebo. When added to pioglitazone, Tesavel reduced HbA1c levels by 0.85% after 24 weeks, compared with a fall of 0.15% in the patients adding placebo.

In the studies comparing Tesavel with other medicines, the effectiveness of adding Tesavel to metformin was similar to that of adding glipizide. When taken on their own, Tesavel and metformin produced similar reductions in HbA1c levels, but the effectiveness of Tesavel seemed to be slightly lower than that of metformin.

In the additional studies, adding Tesavel to glimepiride (with and without metformin) led to a reduction in HbA1c levels of 0.45% after 24 weeks, compared with an increase of 0.28% in the patients adding placebo. HbA1c levels were reduced by 1.03% after 18 weeks in patients adding Tesavel to metformin and rosiglitazone, compared with a fall of 0.31% in those adding placebo. Finally, they were reduced by 0.59% in patients adding Tesavel to insulin (with or without metformin), compared with a fall of 0.03% in those adding placebo.

Serious side effects reported with Tesavel include pancreatitis (inflammation of the pancreas) and hypersensitivity (allergic reactions). Hypoglycaemia has been reported in combination with a sulphonylurea in 4.7-13.8% of patients and with insulin in 9.6% of patients. For the full list of all side effects reported with Tesavel, see the package leaflet.

Tesavel must not be used in people who are hypersensitive (allergic) to sitagliptin or any of the other ingredients.

The CHMP decided that Tesavel’s benefits are greater than its risks and recommended that it be given marketing authorisation.

The European Commission granted a marketing authorisation valid throughout the European Union for Tesavel on 10 January 2008. This authorisation was based on the authorisation granted to Januvia in 2007 (‘informed consent’).

Therapeutic indication

For patients with type-2 diabetes mellitus, Tesavel is indicated to improve glycaemic control:

  • as monotherapy:
    • in patients inadequately controlled by diet and exercise alone and for whom metformin is inappropriate due to contraindications or intolerance;
  • as dual oral therapy in combination with:
    • metformin when diet and exercise plus metformin alone do not provide adequate glycaemic control;
    • a sulphonylurea when diet and exercise plus maximal tolerated dose of a sulphonylurea alone do not provide adequate glycaemic control and when metformin is inappropriate due to contraindications or intolerance;
    • a PPAR? agonist (i.e. a thiazolidinedione) when use of a PPAR? agonist is appropriate and when diet and exercise plus the PPAR? agonist alone do not provide adequate glycaemic control;
  • as triple oral therapy in combination with
    • a sulphonylurea and metformin when diet and exercise plus dual therapy with these agents do not provide adequate glycaemic control;
    • a peroxisome-proliferator-activated-receptor-gamma (PPAR?) agonist and metformin when use of a PPAR? agonist is appropriate and when diet and exercise plus dual therapy with these agents do not provide adequate glycaemic control.

Tesavel is also indicated as add on to insulin (with or without metformin) when diet and exercise plus stable dosage of insulin do not provide adequate glycaemic control.
