Ipsen (Euronext: IPN; ADR: IPSEY) (Ipsen), today announced that the U.S. Food and Drug Administration (FDA) has approved a supplemental indication for Somatuline® Depot (lanreotide) Injection 120 mg for the treatment of carcinoid syndrome; when used, it reduces the frequency of short-acting somatostatin analogue rescue therapy.
Somatuline® Depot is also approved for the improvement of progression-free survival (PFS) in patients with unresectable, well- or moderately-differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Alexandre Lebeaut, MD, Executive Vice-President, R&D, Chief Scientific Officer, Ipsen, said: “The new indication for Somatuline® Depot offers patients in the U.S. a valuable treatment option for debilitating carcinoid syndrome associated with neuroendocrine tumors. It also reaffirms Ipsen’s global commitment to helping to improve lives of patients with cancer.”
“This new indication for Somatuline® Depot gives doctors the only somatostatin analog approved by the FDA in adults for both improving progression-free survival in patients with unresectable, well- or moderately- differentiated, locally advanced or metastatic GEP-NETs and for the treatment of carcinoid syndrome,” said Cynthia Schwalm, Executive Vice-President, and President, North American Commercial Operations, Ipsen. “The additional approval also confirms Ipsen’s commitment to developing research-driven treatments intended to help provide patients battling cancer with new therapy options.”
The additional Somatuline® Depot approval for carcinoid syndrome was based on “Evaluation of Lanreotide Depot/Autogel Efficacy and Safety as a Carcinoid Syndrome Treatment (ELECT): A Randomized, Double-Blind, Placebo-Controlled Trial,” published in Endocrine Practice.1,2
IMPORTANT SAFETY INFORMATION
- Somatuline® Depot is contraindicated in patients with hypersensitivity to lanreotide. Allergic reactions (including angioedema and anaphylaxis) have been reported following administration of lanreotide.
Warnings and Precautions
- Cholelithiasis and Gallbladder Sludge
- Somatuline® Depot may reduce gallbladder motility and lead to gallstone formation.
- Periodic monitoring may be needed.
- Hypoglycemia or Hyperglycemia
- Pharmacological studies show that Somatuline® Depot, like somatostatin and other somatostatin analogs, inhibits the secretion of insulin and glucagon. Patients treated with Somatuline® Depot may experience hypoglycemia or hyperglycemia.
- Blood glucose levels should be monitored when Somatuline® Depot treatment is initiated, or when the dose is altered, and antidiabetic treatment should be adjusted accordingly.
- Cardiovascular Abnormalities
- Somatuline® Depot may decrease heart rate.
- In patients in the GEP-NET pivotal trial, 23% of Somatuline® Depot-treated patients had a heart rate of less than 60 bpm compared to 16% of placebo-treated patients. The incidence of bradycardia was similar in the treatment groups. Initiate appropriate medical management in patients with symptomatic bradycardia.
- In patients without underlying cardiac disease, Somatuline® Depot may lead to a decrease in heart rate without necessarily reaching the threshold of bradycardia. In patients suffering from cardiac disorders prior to treatment, sinus bradycardia may occur. Care should be taken when initiating treatment in patients with bradycardia.
Most Common Adverse Reactions
- GEP-NETs: Adverse reactions occurring in greater than 10% of patients who received Somatuline® Depot in the GEP-NET trial were abdominal pain (34%), musculoskeletal pain (19%), vomiting (19%), headache (16%), injection site reaction (15%), hyperglycemia (14%), hypertension (14%), and cholelithiasis (14%).
- Carcinoid Syndrome: Adverse reactions occurring in the carcinoid syndrome trial were generally similar to those in the GEP-NET trial. Adverse reactions occurring in greater than 5% of patients who received Somatuline® Depot in the carcinoid syndrome trial and occurring at least 5% greater than placebo were headache (12%), dizziness (7%) and muscle spasm (5%).
Drug Interactions: Somatuline® Depot may decrease the absorption of cyclosporine (dosage adjustment may be needed); increase the absorption of bromocriptine; and require dosage adjustment for bradycardia-inducing drugs (e.g., beta-blockers).
- Lactation: Advise women not to breastfeed during treatment and for 6 months after the last dose.
