5 Warnings and Precautions

5.6 Steatorrhea and Malabsorption of Dietary Fats

Additions and/or revisions underlined:

New onset steatorrhea, stool discoloration and loose stools have been reported in patients receiving somatostatin analogs, including SOMATULINE DEPOT. Somatostatin analogs reversibly inhibit secretion of pancreatic enzymes and bile acids, which may result in malabsorption of dietary fats and subsequent symptoms of steatorrhea, loose stools, abdominal bloating, and weight loss. If new occurrence or worsening of these symptoms are reported in patients receiving SOMATULINE DEPOT, evaluate patients for potential pancreatic exocrine insufficiency and manage accordingly.

6 Adverse Reactions

Addition of the following to the bulleted line listing:

  • Steatorrhea and Malabsorption of Dietary Fats [see Warnings and Precautions (5.6)]

6.3 Postmarketing Experience

Additions and/or revisions underlined:

The following adverse reactions have been identified during post-approval use of SOMATULINE DEPOT. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Gastrointestinal disorders: pancreatic exocrine insufficiency

Hepatobiliary: steatorrhea; cholecystitis, cholangitis, pancreatitis, which have sometimes required cholecystectomy

Hypersensitivity: angioedema and anaphylaxis

Injection site reactions: injection site abscess

Additions and/or revisions underlined:

What are the possible side effects of SOMATULINE DEPOT?

SOMATULINE DEPOT may cause serious side effects, including:

  • Fatty stool. SOMATULINE DEPOT may cause your body to have issues absorbing dietary fats. Tell your healthcare provider if you have any new or worsening symptoms including fatty stools, changes in the color of your stools, loose stools, stomach (abdominal) bloating or weight loss.

PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined:

Steatorrhea and Malabsorption of Dietary Fats

Advise patients to contact their healthcare provider if they experience new or worsening symptoms of steatorrhea, stool discoloration, loose stools, abdominal bloating, and weight loss [see Warnings and Precautions (5.6)].

5 Warnings and Precautions

5.1 Cholelithiasis and Complications of Cholelithiasis

(additions underlined)

SOMATULINE DEPOT may reduce gallbladder motility and lead to gallstone formation; therefore, patients may need to be monitored periodically. There have been postmarketing reports of cholelithiasis (gallstones) resulting in complications, including cholecystitis, cholangitis, and pancreatitis, and requiring cholecystectomy in patients taking SOMATULINE DEPOT. If complications of cholelithiasis are suspected, discontinue SOMATULINE DEPOT and treat appropriately.

6 Adverse Reactions

6.1 Clinical Trials Experience

Newly added information:

Carcinoid Syndrome

The safety of SOMATULINE DEPOT 120 mg in patients with histopathologically confirmed neuroendocrine tumors and a history of carcinoid syndrome (flushing and/or diarrhea) was evaluated in Study 4, a double-blind, placebo-controlled trial. Patients were randomized to receive SOMATULINE DEPOT (N=59) or placebo (N=56) administered by deep subcutaneous injection once every 4 weeks. Patients in both arms of Study 4 had access to subcutaneous octreotide as rescue medication for symptom control.

Adverse reactions reported in Study 4 were generally similar to those reported in Study 3 for the GEP-NETs population shown in Table 3 above. Adverse reactions occurring in Study 4 in 5% and greater of SOMATULINE DEPOT-treated patients and occurring at least 5% more than in placebo-treated patients were headache (12% vs 5%, respectively), dizziness (7% vs 0%, respectively), and muscle spasm (5% vs 0%, respectively) by week 16.

6.2 Immunogenicity

Additions and/or revisions underlined:

As with all peptides, there is potential for immunogenicity. The detection of antibody formation … timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to lanreotide in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.

Assessment for neutralizing antibodies was not conducted.  In Study 4, less than 2% (2 of 108) of the patients treated with SOMATULINE DEPOT  developed anti-lanreotide antibodies.

6.3 Postmarketing Experience

Additions and/or revisions underlined:

 The following adverse reactions have been identified during post-approval use of SOMATULINE DEPOT. Because these reactions are reported voluntarily from a population …

Hepatobiliary: Steatorrhea, cholecystitis, pancreatitis

Body as a Whole: angioedema and anaphylaxis

7 Drug Interactions

Additions and/or revisions underlined:

7.2 Cyclosporine

Concomitant administration of cyclosporine with SOMATULINE DEPOT may decrease the  absorption of cyclosporine, and therefore, may necessitate adjustment of cyclosporine dose to maintain therapeutic drug concentrations.

7.3 Bromocriptine

Limited published data indicate that concomitant administration of a somatostatin analog and bromocriptine may

increase the absorption of bromocriptine.

7.4 Bradycardia-Inducing Drugs

Concomitant administration of bradycardia-inducing drugs (e.g., beta-blockers) …

7.5 Drug Metabolism Interactions

Since it cannot be excluded that  SOMATULINE DEPOT may have this effect, avoid other drugs mainly metabolized by CYP3A4 and which have a low therapeutic index (e.g., quinidine, terfenadine.

8 Use in Specific Populations

Additions and/or revisions underlined:

8.5 Geriatric Use

… in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Studies 3 and 4, conducted in patients with  neuroendocrine tumors, did not include sufficient numbers of patients

8.1 Pregnancy

PLLR conversion; as below:

Risk Summary

Limited available data based on postmarketing case reports with SOMATULINE DEPOT use in pregnant women are not sufficient to determine a drug-associated risk of adverse developmental outcomes. In animal reproduction studies, decreased embryo/fetal survival was observed in pregnant rats and rabbits at subcutaneous doses 5- and 2-times the maximum recommended human dose (MRHD) of 120 mg, respectively.

The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

A reproductive study in pregnant rats given 30 mg/kg of lanreotide by subcutaneous injection every 2 weeks (5 times the human dose, based on body surface area comparisons) resulted in decreased embryo/fetal survival. A study in pregnant rabbits given subcutaneous injections of 0.45 mg/kg/day (2 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.

8.2 Lactation

PLLR conversion, as below:

Risk Summary

There is no information available on the presence of lanreotide in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. Studies show that lanreotide acetate administered subcutaneously passes into the milk of lactating rats; however, due to specifies-specific differences in lactation physiology, animal data may not reliably predict drug levels in human milk. Because of the potential for serious adverse reactions in breastfed infants from SOMATULINE DEPOT, including effects on glucose metabolism and bradycardia, advise women not to breastfeed during treatment with SOMATULINE DEPOT and for 6 months (6 half-lives) following the last dose.

8.3 Females and Males of Reproductive Potential

PLLR conversion, as below:

Infertility

Females

Based on results from animal studies conducted in female rats, SOMATULINE DEPOT may reduce fertility in females of reproductive potential.
