Rolapitant (INN, trade name Varubi  və-ROO-bee in the US and Varuby in the European Union) is a drug originally developed by Schering-Plough and licensed for clinical development by Tesaro, which acts as a selective NK1 receptor antagonist (antagonist for the NK1 receptor). It has been approved as a medication for the treatment of chemotherapy-induced nausea and vomiting (CINV) after clinical trials showed it to have similar or improved efficacy and some improvement in safety over existing drugs for this application. Medical uses
Rolapitant is used in combination with other antiemetic (anti-vomiting) agents in adults for the prevention of delayed nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy, including, but not limited to, highly emetogenic chemotherapy. The approved antiemetic combination consists of rolapitant plus dexamethasone and a 5-HT3 antagonist. Contraindications
Under the US approval, rolapitant is contraindicated in combination with thioridazine, whose inactivation could be inhibited by rolapitant. Under the European approval, it is contraindicated in combination with St. Johns Wort, which is expected to accelerate inactivation of rolapitant. Side effects
In studies comparing chemotherapy plus rolapitant, dexamethasone and a 5-HT3 antagonist to chemotherapy plus placebo, dexamethasone and a 5-HT3 antagonist, most side effects had comparable frequencies in both groups, and differed more between chemotherapy regimens than between rolapitant and placebo groups. Common side effects included decreased appetite (9% under rolapitant vs. 7% under placebo), neutropenia (9% vs. 8% or 7% vs. 6%, depending on the kind of chemotherapy), dizziness (6% vs. 4%), indigestion and stomatitis (both 4% vs. 2%).
There are currently significant efforts underway to develop additional treatments that address the underlying causes of neurocutaneous syndromes.Neurocutaneous syndromes are complex, lifelong conditions that have the potential to affect many different organ systems over time. Thus, patients may benefit from a multidisciplinary approach for care. Integrated, multidisciplinary clinics have developed in an effort to optimize the long-term care for patients with neurocutaneous syndromes. Specialties represented at these clinics may include genetics, neurology, ophthalmology, hematology-oncology, neurosurgery, psychiatry, dermatology and more. References
