Uptravi

Uptravi can only be obtained with a prescription and treatment should only be started and monitored by a doctor who has experience in the treatment of PAH.

Uptravi is available as tablets (200; 400; 600; 800; 1,000; 1,200; 1,400 and 1,600 micrograms). Treatment should be started at a dose of 200 micrograms twice a day, approximately 12 hours apart. The dose is then increased weekly, as long as it is tolerated, to a maximum of 1,600 micrograms twice daily, which is then continued afterwards. Patients may tolerate treatment better if they take their tablets with food and take the first tablet of an increased dose in the evening rather than the morning. If the patient cannot tolerate an increased dose, the doctor may have to reduce it.

If stopping treatment with Uptravi, the dose should be reduced gradually.

Patients with severely reduced liver function should not take Uptravi. Patients with moderately reduced liver function should start with 200 micrograms once daily. If tolerated, this dose can be increased weekly. For further information, see the package leaflet.

PAH is a debilitating disease where there is severe narrowing of the blood vessels of the lungs. This leads to high blood pressure in the vessels taking blood from the heart to the lungs and reduces the amount of oxygen that can get into the blood in the lungs, making physical activity more difficult.

The active substance in Uptravi, selexipag, is a ‘prostacyclin receptor agonist’. This means that it works in a similar way to prostacyclin, a naturally occurring substance that regulates blood pressure by attaching to receptors in the muscles of blood vessel walls, causing the vessels to relax and widen. By attaching to prostacyclin receptors, Uptravi also widens the blood vessels and so lowers the pressure inside them, improving symptoms of the disease.

The benefits of Uptravi for PAH were shown in one main study involving 1,156 patients with PAH. Patients were given either Uptravi or placebo (a dummy treatment) for around 70 weeks. Patients were either previously untreated or receiving treatment with other PAH medicines (ERA or PDE-5 inhibitors). The main measure of effectiveness was based on the number of patients whose disease worsened or who died during treatment or shortly after treatment had ended. Overall, 24.4% (140 out of 574) of patients treated with Uptravi either died or showed signs of worsening disease compared with 36.4% (212 out of 582) of patients treated with placebo.

Uptravi is a medicine used to treat adults with pulmonary arterial hypertension (PAH, abnormally high blood pressure in the arteries of the lungs). It can be used in combination with other medicines called endothelin receptor antagonists (ERA) or phosphodiesterase type-5 (PDE-5) inhibitors or on its own for patients for whom these medicines are not suitable. Uptravi is used in patients with functional class II or III PAH. The ‘class’ reflects the severity of the disease: ‘class II’ involves slight limitation of physical activity while ‘class III’ involves marked limitation of physical activity.

Uptravi contains the active substance selexipag.

The most common side effects with Uptravi (which may affect more than 1 in 10 people) are headache, diarrhoea, nausea and vomiting, jaw pain, myalgia (muscle pain), pain in the limbs, arthralgia (joint pain) and flushing. These effects are mild or moderate and are most frequently seen while the dose of Uptravi is being increased.

Uptravi must not be used in patients who have had a heart attack within the last 6 months, severe coronary heart disease (heart disease caused by the obstruction of the blood vessels that supply the heart muscle) or unstable angina (a severe type of chest pain). It must not be used in patients with severe arrhythmias (unstable heartbeat) or defects in the heart valves. For patients with other heart problems, Uptravi must only be used under close medical supervision. It must also not be used in patients who have had a stroke within the last 3 months. Uptravi must not be taken at the same time as medicines, such as gemfibrozil, that are strong blockers (inhibitors) of the liver enzyme CYP2C8.

For the full list of restrictions and side effects reported with Uptravi, see the package leaflet.

Any prescriber of Uptravi will have to register first with the company that markets Uptravi before being able to prescribe it. The company will provide educational materials for the healthcare professionals who will prescribe and dispense the medicine to help them prescribe the medicine correctly and avoid medication errors. These materials will also include a guide and diary to be given to patients to help them keep track of the number of tablets to take and explain how doses should be increased. The diary contains boxes for the patient to mark the number and strength of tablets they take each day.

Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Uptravi have also been included in the summary of product characteristics and the package leaflet.

The European Commission granted a marketing authorisation valid throughout the European Union for Uptravi on 12 May 2016.

The Agency’s Committee for Medicinal Products for Human Use (CHMP) decided that Uptravi’s benefits are greater than its risks and recommended that it be approved for use in the EU. Patients with PAH currently have very limited treatment options; therefore there is a high unmet medical need. Uptravi has been shown to be more effective than placebo at preventing worsening of PAH, on its own and when used in addition to an ERA and/or a PDE-5 inhibitor. Compared with other medicines in the same class which are given into a vein, Uptravi has the advantage of being given by mouth. Regarding safety, the side effects with Uptravi are considered acceptable. Although the CHMP noted a small apparent increase in the rate of death for patients taking Uptravi when compared with placebo, they considered that this was due to chance or to the way the study was designed and therefore did not impact the benefits or risks of the medicine.
