4.4      Special warnings and precautions for use

Xultophy should not be used in patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis.

Hypoglycaemia

Hypoglycaemia may occur if the dose of Xultophy is higher than required. Omission of a meal or unplanned strenuous physical exercise may lead to hypoglycaemia. In combination with sulfonylurea, the risk of hypoglycaemia may be lowered by a reduction in the dose of sulfonylurea. Concomitant diseases in the kidney, liver or diseases affecting the adrenal, pituitary or thyroid gland may require changes of the Xultophy dose. Patients whose blood glucose control is greatly improved (e.g. by intensified therapy) may experience a change in their usual warning symptoms of hypoglycaemia and must be advised accordingly. Usual warning symptoms (see section 4.8) of hypoglycaemia may disappear in patients with long-standing diabetes. The prolonged effect of Xultophy may delay recovery from hypoglycaemia.

Hyperglycaemia

Inadequate dosing and/or discontinuation of antidiabetic treatment may lead to hyperglycaemia and potentially to hyperosmolar coma. In case of discontinuation of Xultophy, ensure that instruction for initiation of alternative antidiabetic treatment is followed. Furthermore, concomitant illness, especially infections, may lead to hyperglycaemia and thereby cause an increased requirement for antidiabetic treatment. Usually, the first symptoms of hyperglycaemia develop gradually over a period of hours or days. They include thirst, increased frequency of urination, nausea, vomiting, drowsiness, flushed dry skin, dry mouth, and loss of appetite as well as acetone odour of breath.
Administration of rapid-acting insulin should be considered in situations of severe hyperglycaemia.
Untreated hyperglycaemic events eventually lead to hyperosmolar coma/diabetic ketoacidosis, which is potentially lethal.

Skin and subcutaneous tissue disorders

Patients must be instructed to perform continuous rotation of the injection site to reduce the risk of developing lipodystrophy and cutaneous amyloidosis. There is a potential risk of delayed insulin absorption and worsened glycaemic control following insulin injections at sites with these reactions. A sudden change in the injection site to an unaffected area has been reported to result in hypoglycaemia.
Blood glucose monitoring is recommended after the change in the injection site from an affected to an unaffected area, and dose adjustment of antidiabetic medications may be considered.


Combination of pioglitazone and insulin medicinal products
Cases of cardiac failure have been reported when pioglitazone was used in combination with insulin medicinal products, especially in patients with risk factors for development of cardiac failure. This should be kept in mind if treatment with the combination of pioglitazone and Xultophy is considered.
If the combination is used, 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.

Eye disorder

Intensification of therapy with insulin, a component of Xultophy, with abrupt improvement in glycaemic control may be associated with temporary worsening of diabetic retinopathy, while long- term improved glycaemic control decreases the risk of progression of diabetic retinopathy.

Antibody formation

Administration of Xultophy may cause formation of antibodies against insulin degludec and/or liraglutide. In rare cases, the presence of such antibodies may necessitate adjustment of the Xultophy dose in order to correct a tendency to hyper- or hypoglycaemia. Very few patients developed insulin degludec specific antibodies, antibodies cross-reacting to human insulin or anti-liraglutide antibodies following treatment with Xultophy. Antibody formation has not been associated with reduced efficacy of Xultophy.

Acute pancreatitis

Acute pancreatitis has been observed with the use of GLP-1 receptor agonists, including liraglutide.
Patients should be informed of the characteristic symptoms of acute pancreatitis. If pancreatitis is suspected, Xultophy should be discontinued; if acute pancreatitis is confirmed, Xultophy should not be restarted.

Thyroid adverse events

Thyroid adverse events, such as goitre have been reported in clinical trials with GLP-1 receptor agonists including liraglutide, and in particular in patients with pre-existing thyroid disease. Xultophy should therefore be used with caution in these patients.

Inflammatory bowel disease and diabetic gastroparesis

There is no experience with Xultophy in patients with inflammatory bowel disease and diabetic gastroparesis. Xultophy is therefore not recommended in these patients.

Dehydration

Signs and symptoms of dehydration, including renal impairment and acute renal failure have been reported in clinical trials with GLP-1 receptor agonists including liraglutide, a component of Xultophy.
Patients treated with Xultophy should be advised of the potential risk of dehydration in relation to gastrointestinal side effects and take precautions to avoid fluid depletion.

Avoidance of medication errors

Patients must be instructed to always check the pen label before each injection to avoid accidental mix-ups between Xultophy and other injectable diabetes medicinal products.

Patients must visually verify the dialled units on the dose counter of the pen. Therefore, the requirement for patients to self-inject is that they can read the dose counter on the pen. Patients who are blind or have poor vision must be instructed to always get help/assistance from another person who has good vision and is trained in using the insulin device.

To avoid dosing errors and potential overdose, patients and healthcare professionals should never use a syringe to draw the medicinal product from the cartridge in the pre-filled pen.

In the event of blocked needles, patients must follow the instructions described in the instructions for use accompanying the package leaflet (see section 6.6).

Populations not studied

Transfer to Xultophy from doses of basal insulin < 20 and > 50 units has not been studied.

There is no therapeutic experience in patients with congestive heart failure New York Heart Association (NYHA) class IV and Xultophy is therefore not recommended for use in these patients.

Excipients

Xultophy contains less than 1 mmol sodium (23 mg) per dose, therefore the medicinal product is essentially ‘sodium-free’.

Tracability
In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.

Effects on Driving

4.7      Effects on ability to drive and use machines

The patient’s ability to concentrate and react may be impaired as a result of hypoglycaemia. This may constitute a risk in situations where these abilities are of special importance (e.g. driving a car or using machines).

Patients must be advised to take precautions to avoid hypoglycaemia while driving. This is particularly important in those who have reduced or absent awareness of the warning signs of hypoglycaemia or have frequent episodes of hypoglycaemia. The advisability of driving should be considered in these circumstances.
