The US Food and Drug Administration’s (FDA) Endocrinologic and Metabolic Drugs Advisory Committee (EMDAC) has voted unanimously in support of the use of Signifor (pasireotide) for the treatment of patients with Cushing’s disease who require medical therapeutic intervention.
“We are encouraged by today’s favourable advisory committee recommendation for pasireotide in Cushing’s disease and will work closely with the FDA as it completes its review of our application. There is a significant unmet medical need for Cushing’s disease patients and Novartis is committed to providing the endocrinology community with a novel therapeutic approach for this rare and debilitating endocrine disorder,” said Hervé Hoppenot, President, Novartis Oncology.
The recommendation was based on data from clinical trials of pasireotide, including PASPORT-CUSHINGS (PASireotide clinical trial PORTfolio – CUSHING’S disease), the largest randomised phase III study to evaluate a medical therapy in patients with Cushing’s disease. Although not obliged to follow the recommendation, the FDA can seek the advice of its advisory committees as it reviews and decides whether to approve treatments.
Results from the PASPORT-CUSHINGS study found that mean urinary-free cortisol (UFC), the key measure of biochemical control of the disease, was rapidly decreased and sustained in a majority of patients, with a subset of patients reaching normalised levels. The study also showed that, on an average, as UFC levels were reduced, clinical manifestations of Cushing’s disease improved. The most frequently reported adverse events (AEs) (>10 per cent) by investigators for pasireotide were diarrhoea, nausea, hyperglycemia, cholelithiasis, abdominal pain, diabetes mellitus, injection site reactions, fatigue and increased glycosylated hemoglobin (HbA1c), with most events being Grade 1-2. The safety profile of pasireotide was similar to that of other somatostatin analogs (SSA) with the exception of the greater degree of hyperglycemia.
Cushing’s syndrome is an endocrine disorder caused by excessive cortisol, a vital hormone that regulates metabolism, maintains cardiovascular function and helps the body respond to stress. Cushing’s disease is a form of Cushing’s syndrome, in which excess cortisol production is triggered by an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma. It is a rare but serious disease that affects approximately one to two patients per million per year. 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. The first line and most common treatment approach for Cushing’s disease is surgical removal of the tumour.
