The US Food and Drug Administration (FDA) has approved Novartis' Signifor (pasireotide) injection for the treatment of adult patients with Cushing's disease for whom pituitary surgery is not an option or has not been curative.
Signifor is the first medicine to be approved in the US that addresses the underlying mechanism of Cushing's disease, a serious, debilitating endocrine disorder caused by the presence of a non-cancerous pituitary tumour which ultimately leads to excess cortisol in the body.
This approval follows a unanimous recommendation from the FDA Endocrinologic and Metabolic Drugs Advisory Committee (EMDAC) in support of the use of Signifor.
"The FDA approval of Signifor for Cushing's disease brings a novel pituitary-directed therapy to patients with limited treatment options," said Hervé Hoppenot, president, Novartis Oncology. "Today's milestone reinforces Novartis' commitment to addressing unmet needs and advancing treatments for rare pituitary-related disorders."
Cushing's disease most commonly affects adults as young as 20 to 50 years and affects women three times more often than men. It may present with weight gain, central obesity, a round, red full face, severe fatigue and weakness, striae (purple stretch marks), high blood pressure, depression and anxiety. Cushing's disease can cause severe illness and death with mortality up to four times higher than in the healthy population.
The approval is based on data from PASPORT-CUSHINGS (PASireotide clinical trial PORTfolio - CUSHING'S disease), the largest randomized Phase III study to evaluate a medical therapy in patients with Cushing's disease. Results from the PASPORT-CUSHINGS study found that a decrease in mean urinary-free cortisol (UFC), the key measure of biochemical control of the disease, was sustained during the treatment period in most patients with a subset of patients reaching normal levels. The study also showed that certain clinical manifestations of Cushing's disease tended to improve.
"Patients with Cushing's disease may suffer from debilitating manifestations, and there are many serious health complications associated with the disease," said Mary Andrews, CEO and Co-Founder of the US non-profit, The MAGIC Foundation. "The FDA approval of Signifor offers the option of a medical therapy that may help certain patients with Cushing's disease."
In April 2012, the European Commission approved Signiforfor the treatment of adult patients with Cushing's disease for whom surgery is not an option or for whom surgery has failed. Other worldwide regulatory filings for pasireotide for this use are also underway.
Signifor (pasireotide) is approved in the US for the treatment of adult patients with Cushing's disease for whom pituitary surgery is not an option or has not been curative, and in the European Union for the treatment of adult patients with Cushing's disease for whom surgery is not an option or for whom surgery has failed.
For the treatment of Cushing's disease, Signifor has been studied as a twice-daily subcutaneous (sc) injection and is currently being evaluated as a long-acting release (LAR), once-monthly intramuscular (IM) injection as part of a global Phase III program in Cushing's disease and acromegaly. Signifor is a multireceptor targeting somatostatin analog that binds with high affinity to four of the five somatostatin receptor subtypes (sst 1, 2, 3 and 5).
