Use in specific populations

Pregnancy

Pregnancy Category C

Lanreotide has been shown to have an embryocidal effect in rats and rabbits. There are no adequate and well-controlled studies in pregnant women. Somatuline Depot should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Reproductive studies in pregnant rats given 30 mg/kg by subcutaneous injection every 2 weeks (five times the human dose, based on body surface area comparisons) resulted in decreased embryo/fetal survival. Studies in pregnant rabbits given subcutaneous injections of 0.45 mg/kg/day (two times the human therapeutic exposures at the maximum recommended dose of 120 mg, based on comparisons of relative body surface area) shows decreased fetal survival and increased fetal skeletal/soft tissue abnormalities.

Nursing Mothers

It is not known whether lanreotide is excreted in human milk. Many drugs are excreted in human milk. As a result of serious adverse reactions from Somatuline Depot in animals and, potentially in nursing infants, a decision should be made whether to discontinue nursing or discontinue the drug, after taking into account the importance of the drug to the mother.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

No overall differences in safety or effectiveness were observed between elderly patients with acromegaly compared with younger patients and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Study 3, conducted in patients with GEP-NET, did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Acromegaly

It is not necessary to alter the starting dose in elderly patients; lanreotide serum concentrations in the elderly are well within the range of serum concentrations safely tolerated in healthy young subjects. Similarly, it is not necessary to alter the titration or maintenance doses of Somatuline Depot, as dose selection is based on therapeutic response [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3)].

Gastroenteropancreatic Neuroendocrine Tumors

No dose adjustment required. [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)].

Renal Impairment

Acromegaly

Lanreotide has been studied in patients with end-stage renal function on dialysis, but has not been studied in patients with mild, moderate, or severe renal impairment. It is recommended that patients with moderate or severe renal impairment receive a starting dose of lanreotide of 60 mg. Caution should be exercised when considering patients with moderate or severe renal impairment for an extended dosing interval of Somatuline Depot 120 mg every 6 or 8 weeks [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3)].

Gastroenteropancreatic Neuroendocrine Tumors

No effect was observed in total clearance of lanreotide in patients with mild to moderate renal impairment receiving Somatuline Depot 120 mg. Patients with severe renal impairment were not studied [see (Clinical Pharmacology (12.3)].

Hepatic Impairment

Acromegaly

It is recommended that patients with moderate or severe hepatic impairment receive a starting dose of lanreotide of 60 mg. Caution should be exercised when considering patients with moderate or severe hepatic impairment for an extended dosing interval of Somatuline Depot 120 mg every 6 or 8 weeks [see Dosage and Administration (2.1) and Clinical Pharmacology (12.3)].

Gastroenteropancreatic Neuroendocrine Tumors

Somatuline Depot has not been studied in patients with hepatic impairment.

Nonclinical Toxicology

Carcinogenicity, Mutagenicity, Impairment of Fertility

Standard lifetime carcinogenicity bioassays were conducted in mice and rats. Mice were given daily subcutaneous doses of lanreotide acetate at 0.5, 1.5, 5, 10 and 30 mg/kg for 104 weeks. Cutaneous and subcutaneous tumors of fibrous connective tissues at the injection sites were observed at the high dose of 30 mg/kg/day. Fibrosarcomas in both genders and malignant fibrous histiocytomas were observed in males at 30 mg/kg/day resulting in exposures 3-times higher than the clinical therapeutic exposure at the maximum therapeutic dose of 120 mg given by monthly subcutaneous injection based on the AUC values. Rats were given daily subcutaneous doses of lanreotide acetate at 0.1, 0.2, and 0.5 mg/kg for 104 weeks. Increased cutaneous and subcutaneous tumors of fibrous connective tissues at the injection sites were observed at the dose of 0.5 mg/kg/day resulting in exposures less than the clinical therapeutic exposure at 120 mg given by monthly subcutaneous injection. The increased incidence of injection site tumors in rodents is likely related to the increased dosing frequency (daily) in animals compared to monthly dosing in humans and therefore may not be clinically relevant.

Lanreotide was not genotoxic in tests for gene mutations in a bacterial mutagenicity (Ames) assay, or mouse lymphoma cell assay with or without metabolic activation. Lanreotide was not genotoxic in tests for the detection of chromosomal aberrations in a human lymphocyte and in vivo mouse micronucleus assay.

Subcutaneous dosing (30mg/kg/2 wks) before mating and continuing into gestation in rats at doses five times the human clinical exposure (120 mg every 4 weeks) based on mg/m2 had reduced fertility. Gestation length was statistically significantly increased suggesting some delay in parturition at three times the human exposure. The reduction in fertility in non-acromegalic animals is likely related to the pharmacologic activity (decreased growth hormone secretion) of lanreotide acetate.

What is Somatuline Depot?

Somatuline Depot (lanreotide) is a man-made protein that is similar to a hormone in the body called somatostatin. Lanreotide lowers many substances in the body such as insulin and glucagon (involved in regulating blood sugar), growth hormone, and chemicals that affect digestion.

Somatuline Depot is used to treat acromegaly in people who cannot be treated with surgery or radiation.

Somatuline Depot is also used to treat a certain type of tumor that starts in the pancreas or digestive tract and may spread to other parts of the body.

Somatuline Depot is sometimes given when surgery or radiation have been tried without success.

What should I avoid while using Somatuline Depot?

Somatuline Depot can make it harder for your body to absorb other medicines you take by mouth. Ask your doctor about the best schedule for taking all of your needed medicines.
