Inc. 1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of Lanreotide Injection was established from adequate and well-controlled studies of another lanreotide injection product [see Clinical Studies ( 14 )] . Adverse reactions observed in these adequate and well-controlled studies are described below.
Acromegaly The data described below reflect exposure to lanreotide injection in 416 acromegalic patients in seven studies. One study was a fixed-dose pharmacokinetic study. The other six studies were open-label or extension studies, one had a placebo-controlled, run-in period, and another had an active control.
The population was mainly White (329/353, 93%) with a median age of 53 years of age (range 19 to 84 years). 3%) were 75 years of age and older. Patients were evenly matched for sex (205 males and 211 females). , 90 mg injected via the deep subcutaneous route every 4 weeks) over 385 days with a median cumulative dose of 1290 mg.
Of the patients reporting acromegaly, severity at baseline (N=265), serum GH levels were less than 10 ng/mL for 69% (183/265) of the patients and 10 ng/mL or greater for 31% (82/265) of the patients. The most commonly reported adverse reactions reported by greater than 5% of patients who received lanreotide (N=416) in the overall pooled safety studies in acromegaly patients were gastrointestinal disorders (diarrhea, abdominal pain, nausea, constipation, flatulence, vomiting, loose stools), cholelithiasis, and injection site reactions.
Tables 1 and 2 present adverse reaction data from clinical studies with lanreotide in acromegalic patients. The tables include data from a single clinical study and pooled data from seven clinical studies. 1 )] are provided in Table 1.

Adverse Reactions in Long-Term Clinical Trials Table 2 provides the most common adverse reactions (greater than 5%) that occurred in 416 acromegalic patients treated with lanreotide injection pooled from 7 studies compared to those patients from the 2 efficacy studies (Studies 1 and 2).

Hypertension occurred in 7% (11) of patients in the pooled Study 1 and 2 and in 5% (20) of patients in the overall pooled studies. Anemia occurred in 7% (12) of patients in the pooled Study 1 and 2 and in 3% (14) of patients in the overall pooled studies.
Gastrointestinal Adverse Reactions In the pooled clinical studies of lanreotide therapy, a variety of gastrointestinal (GI) reactions occurred, the majority of which were mild to moderate in severity. One percent of acromegalic patients treated with lanreotide in the pooled clinical studies discontinued treatment because of gastrointestinal reactions.
Pancreatitis was reported in less than 1% of patients. Gallbladder Adverse Reactions In clinical studies involving 416 acromegalic patients treated with lanreotide, cholelithiasis and gallbladder sludge were reported in 20% of the patients.
Among 167 acromegalic patients treated with lanreotide who underwent routine evaluation with gallbladder ultrasound, 17% had gallstones at baseline. New cholelithiasis was reported in 12% of patients. 1 )] . Injection Site Reactions In the pooled clinical studies, injection site pain (4%) and injection site mass (2%) were the most frequently reported local adverse drug reactions that occurred with the administration of lanreotide.
In a specific analysis, 20 of 413 patients (5%) presented indurations at the injection site. Injection site adverse reactions were more commonly reported soon after the start of treatment and were less commonly reported as treatment continued.
Such adverse reactions were usually mild or moderate but did lead to withdrawal from clinical studies in two subjects. 2 )] . Cardiac Adverse Reactions In the pooled clinical studies, sinus bradycardia (3%) was the most frequently observed heart rate and rhythm disorder.
All other cardiac adverse drug reactions were observed in less than 1% of patients. 3 )] . A comparative echocardiography study of lanreotide and another somatostatin analog demonstrated no difference in the development of new or worsening valvular regurgitation between the 2 treatments over 1 year.
, at least mild in intensity) was low in both groups of patients throughout the study. Other Adverse Reactions For the most commonly occurring adverse reactions in the pooled analysis, diarrhea, abdominal pain, and cholelithiasis, there was no apparent trend for increasing incidence with age.
GI disorders and renal and urinary disorders were more common in patients with documented hepatic impairment; however, the incidence of cholelithiasis was similar between groups. Gastroenteropancreatic Neuroendocrine Tumors The safety of lanreotide injection 120 mg for the treatment of patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) was evaluated in Study 3, a double-blind, placebo-controlled trial.
Patients in Study 3 were randomized to receive lanreotide (N=101) or placebo (N=103) administered by deep subcutaneous injection once every 4 weeks. The data below reflect exposure to lanreotide in 101 patients with GEP-NETs, including 87 patients exposed for at least 6 months and 72 patients exposed for at least 1 year (median duration of exposure 22 months).
Patients treated with lanreotide had a median age of 64 years (range 30 to 83 years), 53% were men and 96% were White. Eighty-one percent of patients (83/101) in the lanreotide arm and 82% of patients (82/103) in the placebo arm did not have disease progression within 6 months of enrollment and had not received prior therapy for GEP-NETs.
The rates of discontinuation due to treatment-emergent adverse reactions were 5% (5/101 patients) in the lanreotide arm and 3% (3/103 patients) in the placebo arm. Table 3 compares the adverse reactions reported with an incidence of 5% and greater in patients receiving lanreotide injection 120 mg administered every 4 weeks and reported more commonly than placebo.

Patients were randomized to receive lanreotide injection (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 lanreotide-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.
2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of lanreotide. 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
