No added benefit proven for pulmonary arterial hypertension drug, IQWiG finds


Selexipag.svg  

In continuation of my update on Selexipag

Selexipag (trade name: Uptravi) is approved for long-term treatment of pulmonary arterial hypertension (PAH) in adults with moderate to severe symptoms. The drug can be used either as combination therapy with other blood-pressure lowering drugs or as monotherapy in patients who are not candidates for these therapies. Selexipag has been on the market in Germany since May 2016. In an early benefit assessment, the German Institute for Quality and Efficiency in Health Care (IQWiG) has now examined whether this drug has advantages or disadvantages in comparison with the appropriate comparator therapy.

The limitation of the comparator therapy to a specific drug and the subsequent division of the population in the dossier were inadequate. The only study cited by the drug manufacturer for one of its subpopulations compared selexipag with placebo. However, no added benefit can be inferred from such a comparison.

Hence the manufacturer presented no suitable data for the assessment of the added benefit of selexipag, and IQWiG concluded: An added benefit of selexipag in comparison with the appropriate comparator therapy is not proven.

Selective widening of vessels and inhibition of tissue growth

In PAH, the pulmonary artery is narrowed, and the heart has to work harder to pump oxygen-poor blood through the pulmonary artery into the lungs. The permanently increased workload of the right heart chamber decreases the body's oxygen supply. The high blood pressure (hypertension) is often caused by another heart or lung disease, e.g. by chronic obstructive pulmonary disease (COPD) or a congenital heart defect.

Selexipag aims to widen the pulmonary artery and slow down the overload of the heart. The drug is approved for long-term treatment of PAH patients who have no symptoms at rest but who have slight (WHO functional class II) or marked (WHO functional class III) limitation of physical activity. These restrictions cause symptoms such as dyspnoea, tiredness, chest pain, or dizziness. Selexipag is an option as combination therapy in patients insufficiently controlled with an endothelin receptor antagonist (ERA) and/or a phosphodiesterase-5 (PDE-5) inhibitor, or as monotherapy in patients who are not candidates for these therapies.

Selexipag holds promise for treatment of pulmonary hypertension

Living with pulmonary arterial hypertension is challenging, but the chore of treating the rare heart disease may change following promising clinical trial data to be published in the Dec. 24 issue of the New England Journal of Medicine.

Data from the largest study ever of pulmonary hypertension shows the oral medication Selexipag led to a 40 percent reduction in hospitalizations and worsening symptoms among patients with pulmonary hypertension.

Selexipag targets a well-known disease pathway that opens blood vessels to the lungs and improves heart function and is easier to use than PH treatments delivered with infusions or injections.

"For more than two decades we've targeted the prostacyclin pathway to induce vasodilation in these blood vessels in the lung," says senior study author Vallerie McLaughlin, M.D., director of the University of Michigan Pulmonary Hypertension Program.

"But because of the cumbersome nature of treatment, patients would often wait until late stages to begin therapy. Having an oral medication to attack the disease pathway will be a major advancement because less ill patients will be willing to begin this therapy," McLaughlin says.

Selexipag demonstrated effectiveness while its most frequent adverse events were headache, diarrhea, nausea, muscle pain and joint pain. The side effects were considered consistent with prostacyclin therapy.

The medication is not commercially available. Following the phase 3 clinical trial, the U.S. Food and Drug Administration is evaluating the drug.

Pulmonary hypertension, which is high blood pressure in the loop of blood vessels connecting the heart and lungs, can make everyday activities exhausting. It often leads to life-threatening heart failure as the heart works harder to pump blood to the lungs.

The greatest number of cases is reported in women between ages 21 and 40 who most often experience fatigue and shortness of breath.

While a rare disease, research of causes and treatment of pulmonary hypertension is growing. The GRIPHON study is a standout because of its size and scope, enrolling 1,156 patients with pulmonary hypertension from 181 centers from 39 countries in North and South America, Europe, Asia-Pacific and Africa.

FDA Approves Uptravi (selexipag) for Pulmonary Arterial Hypertension

On December 21, the U.S. Food and Drug Administration approved Uptravi (selexipag) tablets to treat adults with pulmonary arterial hypertension (PAH), a chronic, progressive, and debilitating rare lung disease that can lead to death or the need for transplantation. “Uptravi offers an additional treatment option for patients with pulmonary arterial hypertension,” said Ellis Unger, M.D., director of the Office of Drug Evaluation I in the FDA’s Center for Drug Evaluation and Research. “The FDA supports continued efforts to provide new treatment options for rare diseases.”

PAH is high blood pressure that occurs in the arteries that connect the heart to the lungs. It causes the right side of the heart to work harder than normal, which can lead to limitations on exercise ability and shortness of breath, among other more serious complications.

Uptravi belongs to a class of drugs called oral IP prostacyclin receptor agonists. The drug acts by relaxing muscles in the walls of blood vessels to dilate (open) blood vessels and decrease the elevated pressure in the vessels supplying blood to the lungs.

Uptravi’s safety and efficacy were established in a long-term clinical trial of 1,156 participants with PAH. Uptravi was shown to be effective in reducing hospitalization for PAH and reducing the risks of disease progression compared to placebo. Participants were exposed to Uptravi in this trial for a median duration of 1.4 years.

Common side effects observed in those treated with Uptravi in the trial include headache, diarrhea, jaw pain, nausea, muscle pain (myalgia), vomiting, pain in an extremity, and flushing.
