Therapeutic indication

Vildagliptin is indicated in the treatment of type-2 diabetes mellitus in adults:

as monotherapy:

as dual oral therapy in combination with:

as triple oral therapy in combination with:

Vildagliptin is also indicated for use in combination with insulin (with or without metformin) when diet and exercise plus a stable dose of insulin do not provide adequate glycaemic control.

What is Galvus?

Galvus is a medicine that contains the active substance vildagliptin. It is available as tablets (50 mg).

What is Galvus used for?

Galvus is used to treat type-2 diabetes mellitus. It can be used in the following ways:

The medicine can only be obtained with a prescription.

How is Galvus used?

In adults, the recommended dose of Galvus is:

The daily dose should not exceed two tablets (100 mg). In patients with moderate or severe kidney problems, the recommended dose is 50 mg once daily.

How does Galvus 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. The active substance in Galvus, vildagliptin, 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, 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. Together, these processes reduce blood glucose levels and help to control type-2 diabetes.

How has Galvus been studied?

Galvus has been studied in eleven main studies involving a total of over 5,000 patients with type-2 diabetes and insufficient control of blood glucose levels.

Five of these studies looked at the effects of Galvus taken alone in a total of 3,644 patients, comparing it with placebo (a dummy treatment), metformin, rosiglitazone (a thiazolidinedione) or gliclazide (a sulphonylurea).

Four studies compared the effects of Galvus, taken at doses of 50 or 100 mg a day for 24 weeks, with those of placebo, when used as an add-on to existing treatment with metformin (544 patients), pioglitazone (a thiazolidinedione, 463 patients), glimepiride (a sulphonylurea, 515 patients) or insulin (296 patients).

A further study compared Galvus with placebo as an add-on treatment in 318 patients who were already taking metformin and glimepiride.

A further study compared Galvus with placebo as an add-on treatment in 449 patients who were already taking a stable dose of long-acting insulin. Some of the patients were also taking metformin.

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

What benefit has Galvus shown during the studies?

Galvus used on its own was effective at reducing levels of HbA1c, but was less effective than the comparator medicines. In the study comparing Galvus with metformin, significantly better results were seen with metformin: a reduction in HbA1c of 1.5 percentage points after 52 weeks compared with a reduction of around 1 percentage point in patients treated with Galvus.

When used as an add-on to existing treatment for type-2 diabetes, Galvus was more effective than placebo in reducing HbA1c levels. With metformin and with pioglitazone, the 100 mg daily dose was more effective than the 50 mg daily dose, with a reduction in HbA1c levels of between 0.8 and 1.0 percentage points. In combination with glimepiride, both 50 mg and 100 mg daily doses caused a reduction of around 0.6 percentage points. In contrast, patients adding placebo to their existing treatment showed smaller changes in HbA1c levels, ranging from a fall of 0.3 to a rise of 0.2 percentage points.

In combination with metformin and glimepiride, 50 mg Galvus taken twice a day reduced HbA1c levels by 1 percentage point, compared with a reduction of 0.3 percentage points in patients taking placebo.

In the study involving 296 patients taking insulin, adding Galvus caused a greater reduction in HbA1c levels than adding placebo, but the size of this effect was small possibly due to the fact that the study included long-term patients who were less likely to show improvement. However, in another study involving 449 patients taking insulin, the size of this effect was significant. Patients taking Galvus in addition to insulin, with or without metformin, had a reduction in HbA1c levels of 0.77 percentage points, compared with 0.05 percentage points in patients taking placebo in addition to insulin.

What is the risk associated with Galvus?

The most common side effect with Galvus (seen in between 1 and 10 patients in 100) is dizziness. For the full list of all side effects reported with Galvus, including side effects occurring when Galvus is taken with other antidiabetes medicines, see the package leaflet.

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

Because vildagliptin has been associated with liver problems, patients should have tests to check their liver function before treatment with Galvus and at regular intervals during treatment.

Why has Galvus been approved?

The CHMP noted that Galvus was effective as an add-on to metformin, a thiazolidinedione or a sulphonylurea (dual therapy), a sulphonylurea and metformin (triple therapy) or insulin with or without metformin, and concluded that the benefits of the add-on treatment outweigh the risks.

The CHMP also considered the use of Galvus on its own and concluded that it was effective in reducing blood glucose but less so than metformin. Galvus should therefore be used only in patients for whom metformin is inappropriate either because of side effects occurring with metformin or because they have a condition that makes metformin unsuitable for them.
