Actelion wins crucial FDA approval for next-gen lung disease drug Opsumit
MACITENTAN
N-[5-(4-Bromophenyl)-6-[2-[(5-bromo-2-pyrimidinyl)oxy]ethoxy]-4-pyrimidinyl]-N’-propylsulfamide, CAS NO 441798-33-0
Late on Friday the FDA came through with an approval for Actelion’s pulmonary arterial hypertension (PAH) drug Opsumit (macitentan), its next-gen successor to the franchise drug Tracleer.

Macitentan (Opsumit® )is a novel dual endothelin receptor antagonist that resulted from a tailored drug discovery process. Macitentan has a number of potentially key beneficial characteristics – i.e., increased in vivo preclinical efficacy vs. existing ERAs resulting from sustained receptor binding and tissue penetration properties. A clinical pharmacology program indicated a low propensity of macitentan for drug-drug interactions.
Macitentan is an investigational drug being studied for the treatment of pulmonary arterial hypertension. It acts as a dualendothelin receptor antagonist and is being developed by Actelion.[1] A Phase III clinical trial was successfully completed in 2012.[2]
on 22 October 2012 – Actelion (SIX: ATLN) announced that it has submitted a New Drug Application (NDA) to the US Food and Drug Administration (FDA) seeking approval for macitentan (Opsumit®) for the treatment of patients with pulmonary arterial hypertension
Actelion’s experimental lung drug macitentan prolonged overall survival by more than a third according to detailed study data, which the company hopes will convince investors it has a viable follow-up product to secure its commercial future.
Europe’s largest standalone biotech company wants the drug, which treats pulmonary arterial hypertension — a disease that causes high blood pressure in the arteries of the lungs — to replace blockbuster Tracleer.
Tracleer currently makes up 87 percent of sales but loses patent protection in 2015 and has also seen its market share eroded by Gilead’s Letairis.
Pharmacokinetics
Macitentan has an active metabolite, ACT-132577, which is an oxidative depropylation product. Both macitentan and ACT-132577 are mainly excreted in form of hydrolysis products via urine (about 2/3 of all metabolites) and faeces (1/3).[3]
Co-administration of ciclosporin has only a slight effect on the concentrations of macitentan and its active metabolite, whilerifampicin decreases the area under the curve (AUC) of the drug’s blood plasma concentration by 79%, and ketoconazoleapproximately doubles it. This corresponds to the finding that macitentan is mainly metabolised via the liver enzyme CYP3A4.[4]
