Drug Detail:Lanreotide (Lanreotide)
Drug Class: Somatostatin and somatostatin analogs
Usual Adult Dose for Acromegaly
Initial dose: 90 mg, by deep subcutaneous injection, every 4 weeks for 3 months
Comments:
- The goal of treatment is to reduce growth hormone (GH) and insulin-like growth factor (IGF-1) levels to normal.
- Adjust dose after initial 3 months.
- No dose adjustment is required for elderly patients.
Use: 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.
Usual Adult Dose for Neuroendocrine Carcinoma
120 mg, by deep subcutaneous injection, every 4 weeks
Comments: No dose adjustment is required for elderly patients.
Use: Treatment of patients with unresectable, well or moderately-differentiated, locally advanced, or metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) to improve progression-free survival.
Usual Adult Dose for Carcinoid Syndrome
120 mg by deep subcutaneous injection every 4 weeks
Comments: If patients are already being treated for GEP-NETs, do not administer an additional dose for the treatment of carcinoid syndrome.
Use: For the treatment of carcinoid syndrome; when used, it reduces the frequency of short-acting somatostatin analog rescue therapy.
Renal Dose Adjustments
Acromegaly:
- Moderate to severe renal impairment: Initial dose: 60 mg, by deep subcutaneous injection, every 4 weeks for 3 months, followed by dose adjustments as described for non-renally impaired patients.
- Use caution when considering an extended dosing interval (120 mg every 6 or 8 weeks) in moderate or severe renal impairment.
Gastroenteropancreatic Neuroendocrine Tumors:
- No adjustment recommended for mild to moderate renal impairment
- Data not available for severe renal impairment
Liver Dose Adjustments
Acromegaly:
- Moderate to severe hepatic impairment: Initial dose: 60 mg, by deep subcutaneous injection, every 4 weeks for 3 months, followed by dose adjustments as described for non-hepatically impaired patients.
Gastroenteropancreatic Neuroendocrine Tumors:
- Data not available for any level of hepatic impairment
Dose Adjustments
Acromegaly:
After the initial 3 month dosing, adjust dose based on growth hormone (GH) and insulin-like growth factor (IGF-1) levels:
- GH over 1 and up to 2.5 ng/mL, IGF-1 normal, and symptoms controlled: 90 mg, by deep subcutaneous (SC) injection, every 4 weeks
- GH over 2.5 ng/mL, IGF-1 elevated, and/or symptoms uncontrolled: 120 mg, by deep SC injection, every 4 weeks
- GH less than 1 ng/mL, IGF-1 normal, symptoms controlled: 60 mg, by deep SC injection, every 4 weeks
- Adjust dose according to patient response, as judged by a reduction in GH and/or IGF-1 levels, and/or changes in acromegaly symptoms.
- Patients controlled on 60 mg or 90 mg may be considered for an extended dosing interval of 120 mg every 6 or 8 weeks; obtain GH and IGF-1 levels 6 weeks after this change to evaluate persistence of patient response.
- Continued monitoring of patient response with dose adjustments for biochemical and clinical symptom control, as necessary, is recommended.
- No dose adjustment is required for elderly patients.
- No difference in safety and effectiveness was seen in elderly patients, however greater sensitivity cannot be ruled out.
- In general, dose selection for elderly patient should be cautious, starting at the low end of the dosing range.
Gastroenteropancreatic Neuroendocrine Tumors:
- No dose adjustment is required for elderly patients.
