Eucreas is indicated in the treatment of type-2 diabetes mellitus:
- Eucreas is indicated in the treatment of adult patients who are unable to achieve sufficient glycaemic control at their maximally tolerated dose of oral metformin alone or who are already treated with the combination of vildagliptin and metformin as separate tablets.
- Eucreas is indicated in combination with a sulphonylurea (i.e. triple combination therapy) as an adjunct to diet and exercise in patients inadequately controlled with metformin and a sulphonylurea.
- Eucreas is indicated in triple combination therapy with insulin as an adjunct to diet and exercise to improve glycaemic control in patients when insulin at a stable dose and metformin alone do not provide adequate glycaemic control.
What is Eucreas?
Eucreas is a medicine that contains the active substances vildagliptin and metformin hydrochloride. It is available as tablets (50 mg / 850 mg and 50 mg / 1,000 mg).
What is Eucreas used for?
Eucreas is used to treat adults with type-2 diabetes. It is used in the following ways:
- in patients whose disease is insufficiently controlled with the maximum tolerated dose of metformin taken alone;
- in patients who are already taking the combination of vildagliptin and metformin as separate tablets;
- in combination with a sulphonylurea (another type of antidiabetes medicine) together with diet and exercise, in patients whose diabetes is not satisfactorily controlled on metformin and a sulphonylurea;
- in combination with insulin together with diet and exercise, in patients whose diabetes is insufficiently controlled with insulin at a stable dose and metformin.
The medicine can only be obtained with a prescription.
How is Eucreas used?
The recommended dose of Eucreas is one tablet twice a day, with one tablet taken in the morning and one in the evening. The choice of tablet strength to start with depends on the patient’s current treatment and the expected effects of Eucreas, but it is recommended to provide a dose of metformin similar to the dose already being taken. Patients already taking vildagliptin and metformin should switch to Eucreas containing the same amounts of each active substance. Doses of vildagliptin above 100 mg are not recommended. Taking Eucreas with or just after food may reduce any stomach problems caused by metformin.
Eucreas should not be used in patients who have moderate or severe problems with their kidneys or who have problems with their liver. Elderly patients taking Eucreas should have their kidney function monitored regularly.
How does Eucreas work?
Type-2 diabetes is a disease in which the pancreas does not make enough insulin to control the level of glucose (sugar) in the blood or when the body is unable to use insulin effectively. Eucreas contains two active substances, which each have a different mode of action. Vildagliptin, which is a dipeptidyl-peptidase-4 (DPP-4) inhibitor, 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, vildagliptin stimulates the pancreas to produce more insulin when blood glucose levels are high. Vildagliptin does not work when the blood glucose is low. Vildagliptin also reduces the amount of glucose made by the liver, by increasing insulin levels and decreasing the levels of the hormone glucagon. Metformin works mainly by inhibiting glucose production and reducing its absorption in the gut. As a result of the action of both substances, the blood glucose is reduced and this helps to control type-2 diabetes.
How has Eucreas been studied?
Vildagliptin on its own was approved by the European Union (EU) in September 2007 under the name Galvus, and metformin has been available in the EU since 1959. Vildagliptin can be used with metformin in type-2-diabetes patients who are not satisfactorily controlled on metformin alone. The studies with Galvus as an add-on to metformin, metformin and a sulphonylurea, or metformin and insulin have been used to support the use of Eucreas in the same indications. The studies compared Galvus with placebo and measured the levels of a substance in the blood called glycosylated haemoglobin (HbA1c), which gives an indication of how well the blood glucose is controlled.
The applicant also presented the results of two studies showing that the active substances in the two strengths of Eucreas were absorbed in the body in the same way as when they were taken as separate tablets.
What benefit has Eucreas shown during the studies?
Vildagliptin has been shown to be more effective than placebo (a dummy treatment) at reducing HbA1c levels when it was added to metformin. Patients adding vildagliptin had falls in HbA1c levels of 0.88 percentage points after 24 weeks from a starting level of 8.38%. In contrast, patients adding placebo had smaller changes in HbA1c levels, with a rise of 0.23 percentage points from a starting level of 8.3%. In other studies, vildagliptin in combination with metformin has been shown to be more effective than placebo when used with a sulphonylurea or insulin.
What is the risk associated with Eucreas?
The most common side effects with Eucreas (seen in more than 1 patient in 10) are nausea (feeling sick), vomiting, diarrhoea, abdominal (tummy) pain and loss of appetite. For the full list of all side effects reported with Eucreas, see the package leaflet.
Eucreas should not be used in people who may be hypersensitive (allergic) to vildagliptin, metformin or any of the other ingredients. It should also not be used in patients who have diabetic ketoacidosis (high levels of ketones and acids in the blood), diabetic precoma, problems with their kidneys or liver, conditions that may affect the kidneys, or a disease that causes a reduced supply of oxygen to the tissues such as failure of the heart or lungs or a recent heart attack. It should also not be used in patients with alcohol intoxication (excessive alcohol consumption) or alcoholism, or during breast-feeding. For the full list of restrictions, see the package leaflet.
Why has Eucreas been approved?
The CHMP concluded that vildagliptin taken with metformin reduces blood glucose levels and the combination of the two active substances in one tablet may help patients to stick to their treatment. The CHMP also noted that the combination of vildagliptin and metformin was effective as an add-on to a sulphonylurea or insulin. Therefore, the Committee decided that the benefits of Eucreas are greater than its risks and recommended that it be given marketing authorisation.
