Safety and efficacy of pasireotide in dumping syndrome-results from a phase 2, multicentre study.
Dumping syndrome is a prevalent complication of oesophageal and gastric surgery characterised by early (postprandial tachycardia) and late (hypoglycaemia) postprandial symptoms.. To evaluate efficacy and safety of the somatostatin analogue, pasireotide in patients with dumping syndrome after bariatric or upper gastrointestinal cancer surgery.. A single-arm, open-label, multicentre, intrapatient dose-escalation, phase 2 study with 4 phases: screening, 3-month SC (subcutaneous), 3-month IM (intramuscular) and 6-month optional extension IM phase. Primary endpoint was the proportion of patients without hypoglycaemia (plasma glucose <3.3 mmol/L [60 mg/dL] during an oral glucose tolerance test, OGTT) at the end of 3-month SC phase. A ≥50% response rate was considered clinically relevant.. Forty-three patients with late dumping were enrolled; 33 completed the 3-month SC phase and 23 completed the 12-month study. The proportion of patients without hypoglycaemia at month 3 (primary endpoint) was 60.5% (26 of 43; 95% confidence interval, 44.4%-75.0%). Improvement in quality of life was observed during SC phase, which was maintained in the IM phase. The proportion of patients with a rise in pulse rate of ≥10 beats/min during OGTT reduced from baseline (60.5%) to month 3 (18.6%) and month 12 (27.3%). Overall (month 0-12), the most frequent (>20% of patients) adverse events were headache (34.9%); diarrhoea, hypoglycaemia (27.9% each); fatigue, nausea (23.3% each); and abdominal pain (20.9%).. These results suggest that pasireotide is a promising option in patients with dumping syndrome after bariatric or upper gastrointestinal cancer surgery.

Pharmacokinetics and safety of subcutaneous pasireotide and intramuscular pasireotide long-acting release in Chinese male healthy volunteers: a phase I, single-center, open-label, randomized study.
The purpose of this study was to assess the pharmacokinetic (PK) properties and safety of single and multiple doses of subcutaneous (SC) pasireotide and a single-dose intramuscular (IM) long-acting release (LAR) formulation of pasireotide in Chinese healthy volunteers (HVs) versus the PK properties in Western HVs (pooled from previous PK studies).. In this phase I, single-center, open-label study, 45 Chinese male HVs were evenly randomized to 1 to 9 treatment sequences: each volunteer received a single dose of 300, 600, or 900 μg of pasireotide SC on day 1, followed by administration of the same dose BID from day 15 to the morning of day 19, and then a single IM dose of 20, 40, or 60 mg of pasireotide LAR on day 33. The PK parameters were assessed with noncompartmental analysis. Statistical comparison of PK parameters, including AUC, Cmax, and CL/F from both formulations, was made for Chinese versus Western male HVs. The safety profile was also assessed. Metabolic parameters, including blood glucose, insulin, and glucagon, and measures that reflect the effects of pasireotide LAR on relatively long-term glucose control, lipid metabolism, and systemic concentrations of pancreatic enzymes and thyrotropin were evaluated.. Of the 45 randomized HVs, 42 completed the study per protocol, 1 withdrew his informed consent for personal reasons, and 2 prematurely discontinued the study because of adverse events (AEs). Concentration-time and safety profiles of both formulations were similar to those reported in Western HVs. Mean geometric mean ratios (GMRs) of Chinese versus Western HVs ranged from 0.79 to 1.42. For most primary PK parameters, 90% CIs for GMRs were within a predefined ethnic insensitivity interval (90% CI, 0.70-1.43). After considering age and weight as covariates in the statistical model, the GMRs and 90% CIs for other PK parameters were within the predefined interval (Cmax in single-dose SC administration) or significantly decreased (Cmin,ss in multiple BID SC doses and first peak Cmax in the single-dose LAR formulation). No serious AEs were reported. Both formulations were well tolerated; pasireotide SC caused transient changes in glucose metabolism. Owing to the differential binding affinity to the somatostatin receptor subtypes, pasireotide LAR elicited a concentration-dependent increase of fasting blood glucose, substantial reduction in triglyceride, and a mild decrease in cholesterol. The most frequently reported AEs after single-dose and multiple-dose pasireotide SC were injection site reaction, nausea, dizziness, and diarrhea; most HVs developed diarrhea with single-dose pasireotide LAR.. The pasireotide formulations had similar PK and safety profiles between Chinese and Western male HVs. Thus, no ethnic sensitivity was found for pasireotide SC or LAR.

Safety, tolerability, pharmacokinetics, and pharmacodynamics of a long-acting release (LAR) formulation of pasireotide (SOM230) in patients with gastroenteropancreatic neuroendocrine tumors: results from a randomized, multicenter, open-label, phase I stud
Pasireotide (SOM230), a novel multireceptor ligand somatostatin analog (SSA), binds with high affinity to four of the five somatostatin receptor subtypes (sst1-3, 5). This study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics profiles of pasireotide long-acting release (LAR) formulation in patients with advanced gastroenteropancreatic neuroendocrine tumor (GEP NET) refractory to other SSAs.. In this randomized, multicenter, open-label, phase II study, patients with biopsy-proven primary or metastatic GEP NET refractory to available SSAs were randomly assigned 1:1:1 to receive pasireotide LAR by deep intragluteal injection at a dose of 20, 40, or 60 mg once every 28 days for 3 months.. Forty-two patients received pasireotide LAR. Adverse events were reported by 34 (81 %) patients, with the most frequently reported including diarrhea, fatigue, abdominal pain, and nausea. Mean fasting glucose levels were increased compared with baseline at all points throughout the study. After the third injection of pasireotide LAR, the median trough plasma concentrations on day 84 were 4.82, 12.0, and 19.7 ng/mL in the 20-, 40-, and 60-mg treatment groups, respectively. Drug accumulation was limited for each dose based on the increase in trough concentrations after the first to third injections (accumulation ratios were approximately 1 from all dose levels).. This study demonstrated that a new, once-monthly, intramuscular LAR formulation of pasireotide was well tolerated in patients with advanced GEP NET. Steady state levels of plasma pasireotide were achieved after three injections.

Safety, tolerability, and pharmacokinetics of a single dose of pasireotide long-acting release in healthy volunteers: a single-center Phase I study.
This study was conducted to evaluate the safety, tolerability, and pharmacokinetics (PKs) of different doses of a long-acting release (LAR) formulation of pasireotide in healthy subjects.. Single-center, open-label, randomized Phase I study.. Twelve healthy male subjects received a single s.c. dose of pasireotide 300 μg followed by a washout period of 7 days (or at least 5 days), before receiving an i.m. injection of pasireotide -LAR 40 mg (n=5) or 60 mg (n=7). Assessments included adverse events (AEs), PKs, and glucose, insulin, glucagon, and HbA1c levels.. Pasireotide LAR showed an extended-release profile over 1 month with two concentration peaks observed 1 and around 20 days after injection. The area under curve exposure of pasireotide LAR was dose proportional when the dose levels were compared, and the bioavailability of the LAR relative to the s.c. formulation was complete. Administration of pasireotide LAR resulted in an increase in fasting and postprandial glucose levels; however, an attenuation of the hyperglycemic effect was observed after 15 days. The most frequently reported AEs were mild-to-moderate diarrhea, abdominal pain, and flatulence. Only gastrointestinal AEs and injection site reactions were suspected to be drug related.. Pasireotide LAR was generally well tolerated with mostly mild AEs at doses up to 60 mg and showed a dose-proportional, extended-release profile in healthy subjects. Based on the favorable results of this study, further clinical development of pasireotide LAR is under way, which will give insight into the PKs, efficacy, and safety of pasireotide LAR in patient populations.

Multiple once-daily subcutaneous doses of pasireotide were well tolerated in healthy male volunteers: a randomized, double-blind, placebo-controlled, cross-over, Phase I study.
A randomized, double-blind, placebo-controlled, cross-over, dose-escalating, single-center study was conducted to evaluate the safety, tolerability, and pharmacokinetic (PK) profile of multiple once-daily (qd) subcutaneous (sc) doses of pasireotide in healthy male subjects. Subjects received pasireotide 50, 200, or 600 μg sc qd for 14 days and placebo in separate sequences. Thirty-three subjects were randomized. The most frequently reported drug-related adverse events were injection-site reactions (n = 18), diarrhea (n = 14) and nausea (n = 10), which were mostly mild or moderate in intensity. Pasireotide 600 μg sc was associated with pre- and post-prandial elevations in glucose levels relative to placebo; however, this effect was less pronounced on day 14 compared with day 1. PK steady state appeared to be achieved after 3 days of dosing and PK exposures had a moderate accumulation of 20-40 % across doses. Pasireotide demonstrated fast absorption (T(max,ss): 0.25-0.5 h), low clearance (CL/F(ss): 8.10-9.03 L/h), long effective half-life (T(½,eff): ~12 h, on average between 9.7 and 13.1 h for 50, 200, and 600 μg sc qd), and large volume of distribution (V(z)/F(ss): 251-1,091 L) at steady state. Dose proportionality was confirmed for C(max,ss); other PK parameters (C(max), AUC(0-24 h) and AUC(tau)) were approximately dose proportional. Growth hormone inhibition was observed with pasireotide 200 and 600 μg sc qd. Gallbladder volume increased post-prandially with pasireotide 200 and 600 μg sc qd, which appeared to correlate with reduced levels of cholecystokinin at these doses. Pasireotide was generally well tolerated up to the tested dose of 600 μg qd, with a linear and time-independent PK profile after sc qd dosing in healthy subjects.

Pasireotide (SOM230) shows efficacy and tolerability in the treatment of patients with advanced neuroendocrine tumors refractory or resistant to octreotide LAR: results from a phase II study.
Pasireotide (SOM230) is a novel multireceptor-targeted somatostatin (sst) analog with high binding affinity for sst receptor subtype 1, 2, 3 (sst(1,2,3)) and sst(5). Because of this binding profile, pasireotide may offer symptom control in patients with neuroendocrine tumors (NETs) and carcinoid syndrome no longer responsive to octreotide LAR. This was a phase II, open-label, multicenter study of pasireotide in patients with advanced NET whose symptoms of carcinoid syndrome (diarrhea/flushing) were inadequately controlled by octreotide LAR. Patients received s.c. pasireotide 150 μg twice daily (bid), escalated to a maximum dose of 1200 μg bid until a clinical response was achieved. Forty-four patients were evaluated for efficacy and 45 for tolerability. Pasireotide 600-900 μg s.c. bid effectively controlled the symptoms of diarrhea and flushing in 27% of patients. Evaluation of tumor response in 23 patients showed 13 with stable disease and ten with progressive disease at study end. The most common drug-related adverse events were nausea (27%), abdominal pain (20%), weight loss (20%), and hyperglycemia (16%) and most were of mild or moderate severity. Pasireotide 600-900 μg s.c. bid was effective and generally well tolerated in controlling the symptoms of carcinoid syndrome in 27% of patients with advanced NET refractory or resistant to octreotide LAR therapy.
