- Somatostatin Analog
Lanreotide is a synthetic octapeptide analogue of natural somatostatin which is a peptide inhibitor of multiple endocrine, neuroendocrine, and exocrine mechanisms. Lanreotide displays a greater affinity for somatostatin type 2 (SSTR2) and type 5 (SSTR5) receptors found in pituitary gland, pancreas, and growth hormone (GH) secreting neoplasms of pituitary gland and a lesser affinity for somatostatin receptors 1, 3, and 4. Lanreotide reduces GH secretion and also reduces the levels of insulin-like growth factor 1.

Special Populations: Renal Function Impairment
In patients with ESRD, there is approximately a 2-fold decrease in total serum clearance, with a consequent 2-fold increase in half-life and AUC.
Special Populations: Hepatic Function Impairment
A 30% reduction in clearance was observed in patients with moderate to severe hepatic impairment.
Special Populations: Elderly
Compared with healthy younger subjects, elderly subjects showed an 85% increase in half-life and a 65% increase in mean residence time.
Use: Labeled Indications
Acromegaly: Long-term treatment of acromegalic patients who have had an inadequate response to surgery and/or radiotherapy, or for whom surgery and/or radiotherapy is not an option (the treatment goal is to reduce growth hormone and insulin growth factor-1 levels to normal).
Carcinoid syndrome: Treatment of carcinoid syndrome in adults (to reduce the frequency of short acting somatostatin analog rescue therapy).
Gastroenteropancreatic neuroendocrine tumors: Treatment (to improve progression-free survival) of unresectable, well- or moderately-differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) in adults.
Hypersensitivity to lanreotide or any component of the formulation
Canadian labeling: Additional contraindications (not in the US labeling): Hypersensitivity to somatostatin or related peptides; complicated, untreated bile duct lithiasis
Acromegaly: SubQ: Initial dose: 90 mg once every 4 weeks for 3 months; after initial 3 months, continue monitoring and adjust dose as necessary based on clinical response of patient, growth hormone (GH) levels, and/or insulin-like growth factor 1 (IGF-1) levels as follows:
GH ≤1 ng/mL, IGF-1 normal, symptoms stable: Decrease dose to 60 mg once every 4 weeks; once stabilized on 60 mg once every 4 weeks, may consider regimen of 120 mg once every 6 or 8 weeks (extended-interval dosing)
GH >1 to 2.5 ng/mL, IGF-1 normal, symptoms stable: Continue 90 mg once every 4 weeks; once stabilized on 90 mg once every 4 weeks, may consider regimen of 120 mg once every 6 or 8 weeks (extended-interval dosing)
GH >2.5 ng/mL, IGF-1 elevated and/or uncontrolled symptoms: Increase dose to 120 mg once every 4 weeks
Carcinoid syndrome: SubQ: 120 mg once every 4 weeks (if already receiving lanreotide for treatment of gastroenteropancreatic neuroendocrine tumors [GEP-NETs], do not administer an additional dose for carcinoid syndrome)
GEP-NETs: SubQ: 120 mg once every 4 weeks until disease progression or unacceptable toxicity
Refer to adult dosing.

Concerns related to adverse effects:
• Cholelithiasis: May reduce gall bladder motility, leading to gall stone formation (may be dose- or duration-related); may require periodic monitoring.
• Gastrointestinal effects: Diarrhea and loose stools may occur (may affect intestinal absorption of concurrently-administered medication); abdominal pain may also occur.
• Hyper-/hypoglycemia: Inhibition of insulin and glucagon secretion may affect glucose regulation, leading to hyper-/hypoglycemia. Carefully monitor blood glucose levels with the initiation of therapy and with dosage alterations. Use with caution in patients with diabetes; may require dosage adjustments in antidiabetic therapy.
• Hypersensitivity: Allergic reactions, including angioedema and anaphylaxis, have been reported.
• Thyroid disorders: Decreases (slight) in thyroid function have been observed during treatment for acromegaly; monitor thyroid function tests if clinically indicated. The incidence of clinical hypothyroidism is rare.
• Cardiac disorders: Bradycardia, sinus bradycardia, and hypertension have been observed with therapy. Use with caution in patients with preexisting cardiac disease; monitor heart rate. Patients without preexisting cardiac disease may experience a decrease in heart rate though not to the level of bradycardia. Appropriate medical therapy should be initiated if patients develop symptomatic bradycardia.
• Hepatic impairment: Use with caution in patients with acromegaly with moderate to severe hepatic impairment (systemic exposure may be increased); lower doses are recommended at therapy initiation. Lanreotide has not been studied in patients with neuroendocrine tumors with hepatic impairment.
• Renal impairment: Use with caution in patients with acromegaly with moderate to severe renal impairment; lower initial doses are recommended.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
Serum growth hormone (GH) and insulin-like growth factor 1 (IGF-1) at 3 months and as clinically indicated in acromegaly patients (obtain levels 6 weeks after dose adjustment when switching to extended-interval dosing), glucose levels, thyroid function (where clinically indicated); heart rate, consider periodic gall bladder monitoring
Adverse events were observed in animal reproduction studies. Information related to the use of lanreotide in pregnancy is limited (deMenis 1999) and it is recommended to discontinue therapy during pregnancy (Chandraharan 2003; Melmed 2012).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience flatulence, diarrhea, constipation, joint pain, muscle pain, injection site pain or irritation, or weight loss. Have patient report immediately to prescriber signs of high blood sugar (confusion, feeling sleepy, more thirst, hunger, passing urine more often, flushing, fast breathing, or breath that smells like fruit), signs of low blood sugar (dizziness, headache, fatigue, feeling weak, shaking, a fast heartbeat, confusion, hunger, or sweating), signs of gallstones (pain in the upper right abdominal area, right shoulder area, or between the shoulder blades; yellow skin or eyes; or fever with chills), severe nausea, severe vomiting, severe abdominal pain, severe dizziness, passing out, severe headache, bradycardia, arrhythmia, depression, shortness of breath, or severe loss of strength and energy (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
