Clinical
Pasireotide injection (Signifor® and Signifor LAR®) is used to treat Cushing's disease (an abnormal condition that is caused by excess hormones [cortisol]) in adults who cannot be treated with surgery or who did not respond to surgery. Pasireotide injection (Signifor LAR®) is also used to decrease the amount of growth hormone (a natural substance) produced by people with acromegaly (condition in which the body produces too much growth hormone, causing enlargement of the hands, feet, and facial features; joint pain; and other symptoms) who cannot be treated with surgery or who did not respond t...

Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Full prescribing information FDA SPL
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE SIGNIFOR is a somatostatin analog indicated for the treatment of adult patients with Cushing's disease for whom pituitary surgery is not an option or has not been curative ( 1 )
1.1Cushing's Disease SIGNIFOR is indicated for the treatment of adult patients with Cushing's disease for whom pituitary surgery is not an option or has not been curative.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Recommended initial dosage is either 0.6 mg or 0.9 mg by subcutaneous injection twice a day; recommended dosage range is 0.3 mg to 0.9 mg twice a day ( 2.1 ) Titrate dosage based on treatment response [clinically meaningful reduction in 24-hour urinary free cortisol (UFC) and/or improvements in signs and symptoms of disease] and tolerability ( 2.1 ) Testing Prior to Dosing : fasting plasma glucose (FPG), hemoglobin A1c (HbA1c), liver tests, electrocardiogram (ECG), gallbladder ultrasound, and serum potassium and magnesium levels ( 2.2 ) Patients With Hepatic Impairment : Child-Pugh B: Recommended initial dosage is 0.3 mg twice a day and maximum dosage is 0.6 mg twice a day ( 2.3 , 8.6 ) Child-Pugh C: Avoid use in these patients ( 2.3 , 8.6 )
2.1Recommended Dosage Range The recommended dosage range of SIGNIFOR is 0.3 mg to 0.9 mg by subcutaneous injection twice a day. The recommended initial dose is either 0.6 mg or 0.9 mg twice a day. Titrate dose based on response and tolerability.
Patients should be evaluated for a treatment response [clinically meaningful reduction in 24-hour urinary free cortisol (UFC) levels and/or improvement in signs or symptoms of the disease] and should continue receiving therapy with SIGNIFOR as long as benefit is derived [see Clinical Studies (14)] . Maximum UFC reduction is typically seen by two months of treatment [see Clinical Studies (14)] . For patients who are started on 0.6 mg twice a day, a dosage increase to 0.9 mg twice a day may be considered based on the response to the treatment, as long as the 0.6 mg dosage is well tolerated by the patient.
Management of suspected adverse reactions may require temporary dose reduction of SIGNIFOR. Dose reduction by 0.3 mg decrements per injection is suggested.
2.2Recommendations Prior to Initiation of SIGNIFOR Prior to the start of SIGNIFOR, patients should have baseline levels of the following: fasting plasma glucose (FPG) [see Warnings and Precautions (5.2)] hemoglobin A1c (HbA1c) [see Warnings and Precautions (5.2)] liver tests [see Warnings and Precautions (5.4)] serum potassium and magnesium levels [see Warnings and Precautions (5.3)] Patients should also have a baseline electrocardiogram (ECG) and gallbladder ultrasound [see Warnings and Precautions (5.3, 5.5)] . Treatment of patients with poorly controlled diabetes mellitus should be intensively optimized with anti-diabetic therapy prior to starting SIGNIFOR [see Warnings and Precautions (5.2)] .
2.3Dosage in Patients With Hepatic Impairment For patients with moderate hepatic impairment (Child-Pugh B), the recommended initial dosage is 0.3 mg twice a day and the maximum dosage is 0.6 mg twice a day. Avoid the use of SIGNIFOR in patients with severe hepatic impairment (Child-Pugh C) [see Use in Specific Populations (8.6)] .
2.4Important Administration Instructions Instruct patients to: Refer to the FDA-approved patient labeling (Instructions for Use) for detailed administration instructions. Prior to injection, visually inspect the product for particulate matter and discoloration. Do not use if particulates and/or discoloration are observed.
Avoid injection in sites showing signs of inflammation or irritation. Prior to injection, gently pinch the skin at the injection site and hold the needle/syringe at an angle of approximately 45 degrees. Administer SIGNIFOR subcutaneously by self-injection into the top of the thigh or the abdomen.
Avoid multiple subcutaneous injections at the same site within short periods of time. Use of the same injection site for 2 consecutive injections is not recommended. If a dose of SIGNIFOR is missed, the next injection should be administered at the scheduled time.
Do not double doses to make up for a missed dose.
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS Injection: 0.3 mg/mL, 0.6 mg/mL, and 0.9 mg/mL in a single-dose, 1 mL colorless glass ampule. Injection: 0.3 mg/mL, 0.6 mg/mL, and 0.9 mg/mL in a single-dose ampule ( 3 )
⛔ Contraindications ▾
4 CONTRAINDICATIONS None. None ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypocortisolism : Decreases in circulating levels of cortisol may occur resulting in biochemical and/or clinical hypocortisolism. SIGNIFOR dose reduction or interruption and/or adding a low-dose short-term glucocorticoid may be necessary ( 5.1 ) Hyperglycemia and Diabetes (occurs with initiation) : Intensive glucose monitoring is recommended and may require initiation or adjustment of anti-diabetic treatment per standard of care ( 5.2 ) Bradycardia and QT Prolongation : Use with caution in at-risk patients; ECG testing prior to dosing and on treatment ( 5.3 , 7.1 ) Liver Test Elevations : Evaluate liver tests prior to and during treatment ( 5.4 ) Cholelithiasis and Complications of Cholelithiasis : Monitor periodically.
Discontinue if complications of cholelithiasis are suspected ( 5.5 ) Steatorrhea and Malabsorption of Dietary Fats : New onset steatorrhea, stool discoloration, loose stools, abdominal bloating, and weight loss may occur. If new occurrence or worsening of these symptoms are reported, evaluate for potential pancreatic exocrine insufficiency ( 5.7 )
5.1Hypocortisolism Treatment with SIGNIFOR leads to suppression of adrenocorticotropic hormone (ACTH) secretion in Cushing's disease. Suppression of ACTH may lead to a decrease in circulating levels of cortisol and potentially hypocortisolism. Monitor and instruct patients on the signs and symptoms associated with hypocortisolism (e.g., weakness, fatigue, anorexia, nausea, vomiting, hypotension, hyponatremia, or hypoglycemia).
If hypocortisolism occurs, consider temporary dose reduction or interruption of treatment with SIGNIFOR, as well as temporary, exogenous glucocorticoid replacement therapy.
5.2Hyperglycemia and Diabetes Blood glucose elevations have been seen in healthy volunteers and patients treated with SIGNIFOR. In the clinical study [see Clinical Studies (14)] , patients developed pre-diabetes and diabetes. Nearly all patients in the study, including those with normal glucose status at baseline, pre-diabetes, and diabetes, developed worsening glycemia in the first two weeks of treatment.
Cushing's disease patients with poor glycemic control (HbA1c > 8%) may be at a higher risk of developing severe hyperglycemia and associated complications, e.g., ketoacidosis. Assess the patient's glycemic status prior to starting treatment with SIGNIFOR. In patients with uncontrolled diabetes mellitus, optimize anti-diabetic therapy prior to SIGNIFOR initiation.
Glycemic monitoring should be done every week for the first two to three months and periodically thereafter, as well as over the first two to four weeks after any dose increase. If hyperglycemia develops, initiate or adjust anti-diabetic treatment per standard of care. If uncontrolled hyperglycemia persists despite appropriate treatment, reduce the dose or discontinue SIGNIFOR and perform glycemic monitoring according to clinical practice.
Patients who were initiated on anti-diabetic treatment as a result of SIGNIFOR require closer monitoring after discontinuation of SIGNIFOR, especially if the anti-diabetic therapy has a risk of causing hypoglycemia.
5.3Bradycardia and QT Prolongation Bradycardia Bradycardia has been reported with the use of SIGNIFOR [see Adverse Reactions (6)] . Patients with cardiac disease and/or risk factors for bradycardia, such as history of clinically significant bradycardia, high-grade heart block, or concomitant use of drugs associated with bradycardia, should be carefully monitored. Dose adjustments of beta-blockers, calcium channel blockers, or correction of electrolyte disturbances may be necessary.
QT Prolongation SIGNIFOR is associated with QT prolongation. In two thorough QT studies with SIGNIFOR, QT prolongation occurred at therapeutic and supra-therapeutic doses. SIGNIFOR should be used with caution in patients who are at significant risk of developing prolongation of QTc, such as those: with congenital long QT prolongation. with uncontrolled or signi… [Excerpted — this section continues on DailyMed.]

6 ADVERSE REACTIONS Clinically significant adverse reactions that appear in other sections of the labeling include: Hypocortisolism [see Warnings and Precautions (5.1)] Hyperglycemia and Diabetes [see Warnings and Precautions (5.2)] Bradycardia and QT prolongation [see Warnings and Precautions (5.3)] Liver Test Elevations [see Warnings and Precautions (5.4)] Cholelithiasis and Complications of Cholelithiasis [see Warnings and Precautions (5.5)] Pituitary Hormone Deficiency [see Warnings and Precautions (5.6)] Steatorrhea and Malabsorption of Dietary Fats [see Warnings and Precautions (5.7) ] Most common adverse reactions occurring in ≥ 20% of patients are diarrhea, nausea, hyperglycemia, cholelithiasis, headache, abdominal pain, fatigue, and diabetes mellitus ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Recordati Rare Diseases at 1-888-575-8344 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in practice. A total of 162 Cushing's disease patients were exposed to SIGNIFOR in the Phase III study [see Clinical Studies (14)] . At study entry, patients were randomized to receive twice a day doses of either 0.6 mg or 0.9 mg of SIGNIFOR given subcutaneously.
The mean age of patients was approximately 40 years old with a predominance of female patients (78%). The majority of the patients had persistent or recurrent Cushing's disease (83%) and few patients (≤ 5%) in either treatment group had received previous pituitary irradiation. The median exposure to the treatment was 10.4 months (0.03-37.8) with 68% of patients having at least 6-months exposure.
In the Phase III trial, adverse reactions were reported in 98% of patients. The most common adverse reactions (frequency ≥ 20% in either group) were diarrhea, nausea, hyperglycemia, cholelithiasis, headache, abdominal pain, fatigue, and diabetes mellitus. There were no deaths during the study.
Serious adverse events were reported in 25% of patients. Adverse events leading to study discontinuation were reported in 17% of patients. Adverse reactions with an overall frequency higher than 5% are presented in Table 1 by randomized dose group and overall.
Adverse reactions are ranked by frequency, with the most frequent reactions listed first.

7 DRUG INTERACTIONS Drugs that Prolong QT : Use with caution in patients who are at significant risk of developing QTc prolongation ( 5.3 , 7.1 ) Cyclosporine : Consider additional monitoring ( 7.2 ) Bromocriptine : Consider bromocriptine dose reduction ( 7.2 )
7.1Effects of Other Drugs on SIGNIFOR Drugs That Prolong QT Coadministration of drugs that prolong the QT interval with SIGNIFOR may have additive effects on the prolongation of the QT interval. Caution is required when coadministering SIGNIFOR with drugs that may prolong the QT interval [see Warnings and Precautions (5.3)] .
7.2Effects of SIGNIFOR on Other Drugs Cyclosporine Concomitant administration of cyclosporine with pasireotide may decrease the relative bioavailability of cyclosporine and, therefore, dose adjustment of cyclosporine to maintain therapeutic levels may be necessary. Bromocriptine Coadministration of somatostatin analogues with bromocriptine may increase the blood levels of bromocriptine. Dose reduction of bromocriptine may be necessary.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Females and Males of Reproductive Potential : Advise premenopausal females of the potential for an unintended pregnancy ( 8.3 ) Safety and effectiveness of SIGNIFOR in children under 18 years have not been established ( 8.4 )
8.1Pregnancy Risk Summary The limited data with SIGNIFOR in pregnant women are insufficient to inform a drug-associated risk for major birth defects and miscarriage. In embryo-fetal development studies in rabbits, findings indicating developmental delay were observed with subcutaneous administration of pasireotide during organogenesis at doses less than the exposure in humans at the highest recommended dose; maternal toxicity was not observed at this dose (see Data) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%-4% and 15%-20%, respectively. Data Animal Data In embryo-fetal development studies in rats given 1, 5, and 10 mg/kg/day subcutaneously throughout organogenesis, maternal toxicity was observed at all doses, including the lowest dose tested which had exposures 4 times higher than that at the maximum therapeutic dose based on area under the curve (AUC) comparisons across species.
An increased incidence of early/total resorptions and malrotated limbs was observed in rats at 10 mg/kg/day. At 10 mg/kg/day in rats, the maternal systemic exposure (AUC) was 42179 ng*hr/mL, approximately 144 times the exposure in humans at the highest recommended dose of 900 mcg SIGNIFOR administered as a subcutaneous injection twice a day. In embryo-fetal development studies in rabbits given 0.05, 1, and 5 mg/kg/day subcutaneously through organogenesis, maternal toxicity was observed at 1 mg/kg/day, at a maternal systemic exposure (AUC) of 1906 ng*hr/mL, approximately 7 times higher than the maximum human therapeutic exposure.
An increased incidence of unossified forepaw phalanx, indicative of a developmental retardation, was observed in rabbits at 0.05 mg/kg/day, with maternal systemic exposures less than the systemic exposure in humans at the highest recommended dose. In pre- and post-natal developmental studies in rats given subcutaneous doses of 2, 5, and 10 mg/kg/day during gestation through lactation and weaning, maternal toxicity was observed at all doses, including the lowest dose (12 times higher than the maximum therapeutic dose based on surface area comparisons across species).
Retardation of physiological growth, attributed to GH inhibition was observed at 2 mg/kg/day during a pre- and post-natal study in rats. After weaning, body weight gains in the rat pups (F1 generation) exposed to pasireotide were comparable to controls, showing reversibility of this developmental delay.
8.2Lactation Risk Summary There is no information available on the presence of SIGNIFOR in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. Studies show that pasireotide administered subcutaneously passes into the milk of lactating rats; however, due to species-specific differences in lactation physiology, animal data may not reliably predict drug levels in human milk (see Data) . The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for SIGNIFOR and any potential adverse effects on the breastfed child from SIGNIFOR or from the underlying maternal condition.
Data Available data in animals have shown excretion of pasireotide in milk. After a single 1 mg/kg [ 14 C]-pasireotide subcutaneous dose to lactating rats, the transfer of radioactivity into milk was observed. The overall milk:plasma (M/P) exposure ratio of total radioactivity was 0.28, based on AUC 0-∞ values.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of SIGNIFOR have not been established in pediatric patients.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of SIGNIFOR did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease or other drug therapy [see Clinical Pharmacology (12.3)] .
🆘 Overdosage ▾
10 OVERDOSAGE No cases of overdosage have been reported in patients with Cushing's disease receiving SIGNIFOR subcutaneously. Doses up to 2.1 mg twice a day have been used in healthy volunteers with adverse reactions of diarrhea being observed at a high frequency. In the event of overdosage, it is recommended that appropriate supportive treatment be initiated, as dictated by the patient's clinical status, until resolution of the symptoms.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action SIGNIFOR is an injectable cyclohexapeptide somatostatin analogue. Pasireotide exerts its pharmacological activity via binding to somatostatin receptors (SSTRs). Five human somatostatin receptor subtypes are known: SSTR 1, 2, 3, 4, and 5.
These receptor subtypes are expressed in different tissues under normal physiological conditions. Corticotroph tumor cells from Cushing's disease patients frequently over-express SSTR5 whereas the other receptor subtypes are often not expressed or are expressed at lower levels. Pasireotide binds and activates the SSTRs resulting in inhibition of ACTH secretion, which leads to decreased cortisol secretion.
The binding affinities of endogenous somatostatin and pasireotide are shown in Table 2.

12.2Pharmacodynamics Glucose Metabolism In a randomized, double-blind mechanism study conducted in healthy volunteers, the development of hyperglycemia with pasireotide at doses of 0.6 mg twice a day and 0.9 mg twice a day was related to significant decreases in insulin secretion as well as incretin hormones (i.e., glucagon-like peptide-1 [GLP-1] and glucose-dependent insulinotropic polypeptide [GIP]) [see Warnings and Precautions (5.2), Adverse Reactions (6.1)] . Cardiac Electrophysiology QTcI interval was evaluated in a randomized, blinded, crossover study in healthy subjects investigating pasireotide doses of 0.6 mg twice a day and 1.95 mg twice a day.
The maximum mean (95% upper confidence bound) placebo-subtracted QTcI change from baseline was 12.7 (14.7) ms and 16.6 (18.6) ms, respectively. Both pasireotide doses decreased heart rate, with a maximum mean (95% lower confidence bound) placebo-subtracted change from baseline of -10.9 (-11.9) beats per minute (bpm) observed at 1.5 hours for pasireotide 0.6 mg twice a day, and -15.2 (-16.5) bpm at 0.5 hours for pasireotide 1.95 mg twice a day. The supra-therapeutic dose (1.95 mg twice a day) produced mean steady-state C max values 3.3-fold the mean C max for the 0.6 mg twice a day dose in the study.
12.3Pharmacokinetics In healthy volunteers, pasireotide demonstrates approximately linear pharmacokinetics (PK) for a dose range from 0.0025 to 1.5 mg. In Cushing's disease patients, pasireotide demonstrates linear dose-exposure relationship in a dose range from 0.3 mg to 1.2 mg. Absorption and Distribution In healthy volunteers, pasireotide peak plasma concentration is reached within T max 0.25-0.5 hour.
C max and AUC are dose-proportional following administration of single and multiple doses. No studies have been conducted to evaluate the absolute bioavailability of pasireotide in humans. Food effect is unlikely to occur since SIGNIFOR is administered via a parenteral route.
In healthy volunteers, pasireotide is widely distributed with large apparent volume of distribution (V z /F > 100 L). Distribution between blood and plasma is concentration independent and shows that pasireotide is primarily located in the plasma (91%). Plasma protein binding is moderate (88%) and independent of concentration.
Pasireotide has low passive permeability and is likely to be a substrate of P-glycoprotein (P-gp), but the impact of P-gp on ADME (absorption, distribution, metabolism, excretion) of pasireotide is expected to be low. In clinical testing in healthy volunteers, P-gp inhibition (e.g., verapamil) did not affect the rate or extent of pasireotide availability. Pasireotide is not a substrate of efflux transporter BCRP (breast cancer resistance protein), influx transporter OCT1 (organic cation transporter 1), or influx transporters OATP (organic anion-tra… [Excerpted — this section continues on DailyMed.]

In clinical testing in healthy volunteers, P-gp inhibition (e.g., verapamil) did not affect the rate or extent of pasireotide availability. Pasireotide is not a substrate of efflux transporter BCRP (breast cancer resistance protein), influx transporter OCT1 (organic cation transporter 1), or influx transporters OATP (organic anion-transporting polypeptide) 1B1, 1B3, or 2B1.
Metabolism and Excretion Pasireotide was shown to be metabolically stable in human liver and kidney microsomes systems. In healthy volunteers, pasireotide in its unchanged form is the predominant form found in plasma, urine, and feces. Somatropin may increase CYP450 enzymes and, therefore, suppression of growth hormone secretion by somatostatin analogs, including pasireotide may decrease the metabolic clearance of compounds metabolized by CYP450 enzymes.
Pasireotide is eliminated mainly via hepatic clearance (biliary excretion) with a small contribution of the renal route. In a human ADME study 55.9 ± 6.63% of the radioactivity dose was recovered over the first 10 days post dosing, including 48.3 ± 8.16% of the radioactivity in feces and 7.63 ± 2.03% in urine. The clearance (CL/F) of pasireotide in healthy volunteers and Cushing's disease patients is ~7.6 L/h and ~3.8 L/h, respectively.
Steady-State Pharmacokinetics Following multiple subcutaneous doses, pasireotide demonstrates linear pharmacokinetics in the dose range of 0.05 to 0.6 mg once a day in healthy volunteers, and 0.3 mg to 1.2 mg twice a day in Cushing's disease patients. Based on the accumulation ratios of AUC, the calculated effective half-life (t 1/2,eff ) in healthy volunteers was approximately 12 hours (on average between 10 and 13 hours for 0.05, 0.2 and 0.6 mg once a day doses). Specific Populations Population PK analyses of SIGNIFOR indicate that race, body weight, age, and gender do not have a clinically relevant influence on PK parameters.
No dose adjustment is required for demographics. Hepatic Impairment In a clinical study with a single subcutaneous dose of 600 mcg pasireotide in subjects with impaired hepatic function (Child-Pugh A, B, and C), subjects with moderate and severe hepatic impairment (Child-Pugh B and C) showed significantly higher exposures than subjects with normal hepatic function. Upon comparison with the control group, AUC inf was increased by 12%, 56%, and 42%; and C max increased by 3%, 46%, and 33%, respectively, in the mild, moderate, and severe hepatic impairment groups [see Use in Specific Populations (8.6), Dosage and Administration (2.3)] .

Cardiac Electrophysiology QTcI interval was evaluated in a randomized, blinded, crossover study in healthy subjects investigating pasireotide doses of 0.6 mg twice a day and 1.95 mg twice a day.
The maximum mean (95% upper confidence bound) placebo-subtracted QTcI change from baseline was 12.7 (14.7) ms and 16.6 (18.6) ms, respectively. Both pasireotide doses decreased heart rate, with a maximum mean (95% lower confidence bound) placebo-subtracted change from baseline of -10.9 (-11.9) beats per minute (bpm) observed at 1.5 hours for pasireotide 0.6 mg twice a day, and -15.2 (-16.5) bpm at 0.5 hours for pasireotide 1.95 mg twice a day. The supra-therapeutic dose (1.95 mg twice a day) produced mean steady-state C max values 3.3-fold the mean C max for the 0.6 mg twice a day dose in the study.
🔬 Clinical Studies ▾
14 CLINICAL STUDIES A Phase III, multicenter, randomized study was conducted to evaluate the safety and efficacy of two dose levels of SIGNIFOR over a 6-month treatment period in Cushing's disease patients with persistent or recurrent disease despite pituitary surgery or de novo patients for whom surgery was not indicated or who had refused surgery. Patients with a baseline 24-hour urine free cortisol (UFC) >1.5 x ULN were randomized to receive a SIGNIFOR dosage of either 0.6 mg subcutaneous twice a day or 0.9 mg subcutaneous twice a day.
After 3 months of treatment, patients with a mean 24-hour UFC ≤ 2.0 x ULN and below or equal to their baseline values continued blinded treatment at the randomized dose until Month 6. Patients who did not meet these criteria were unblinded and the dose was increased by 0.3 mg twice a day. After the initial 6 months in the study, patients entered an additional 6-month open-label treatment period.
The dosage could be reduced by 0.3 mg twice a day at any time during the study for intolerability. A total of 162 patients were enrolled in this study. The majority of patients were female (78%) and had persistent or recurrent Cushing's disease despite pituitary surgery (83%) with a mean age of 40 years.
A few patients (4%) in either treatment group received previous pituitary irradiation. The median value of the baseline 24-hour UFC for all patients was 565 nmol/24 hours (normal range 30 to 145 nmol/24 hours). About two-thirds of all randomized patients completed 6 months of treatment.
The primary efficacy endpoint was the proportion of patients who achieved normalization of mean 24-hour UFC levels after 6 months of treatment and did not dose increase during this period. 24-Hour Urinary Free Cortisol Results At Month 6, the percentages of responders for the primary endpoint were 15% and 26% in the 0.6 mg twice a day and 0.9 mg twice a day groups, respectively (Table 3). The percentages of patients with mUFC ≤ ULN or ≥ 50% reduction from baseline, a less stringent endpoint than the primary endpoint, were 34% in the 0.6 mg twice a day and 41% in the 0.9 mg twice a day groups.
Dose increases appeared to have minimal effect on 24-hour UFC response. Mean and median percentage changes in UFC from baseline are presented in Table 3. Table 3 – 24-Hour Urinary Free Cortisol Study Results at Month 6 in Patients With Cushing's Disease SIGNIFOR 0.6 mg twice a day N = 82 SIGNIFOR 0.9 mg twice a day N = 80 UFC Responders n/N % (95% CI) 12/82 15% (7%, 22%) 21/80 26% (17%, 36%) UFC Levels (nmol/24 hr) Baseline Mean (SD) Median N = 78 868 (764) 704 N = 72 750 (930) 470 % Change from baseline Mean (95% CI) Median -22% (-44%, +1%) -47% -42% (-50%, -33%) -46% SIGNIFOR resulted in a decrease in the mean 24-hour UFC after 1 month of treatment (Figure 1).
For patients (n = 78) who stayed in the trial, similar UFC lowering was observed at Month 12. Figure 1 – Mean (± SE) Urinary Free Cortisol (nmol/24h) at Time Points up to Month 6 by Randomized Dose Group Note: Only patients who completed 6 months of treatment are included in this analysis (n = 110). The reference line is the ULN for UFC, which is 145 nmol/24hour; +/-Standard errors are displayed.
Other Endpoints Decreases from baseline for blood pressure were observed at Month 6, including patients who did not receive any anti-hypertensive medication. However, due to the fact that the study allowed initiation of anti-hypertensive medication and dose increases in patients already receiving such medications, the individual contribution of SIGNIFOR or of anti-hypertensive medication adjustments cannot be clearly established. The mean decreases from baseline at Month 6 for weight, body mass index, and waist circumference were 4.4 kg, 1.6 kg/m 2 and 2.6 cm, respectively.
Individual patients showed varying degrees of improvement in Cushing's disease manifestations, but because of the variability in response and the absence of a control group in this trial, it is uncertain whethe… [Excerpted — this section continues on DailyMed.]

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis A life-time carcinogenicity study was conducted in rats and transgenic mice. Rats were given daily subcutaneous doses of pasireotide at 0.01, 0.05, 0.3 mg/kg/day for 104 weeks. There were no drug-related tumors in rats at exposures up to 7-fold higher than the maximum recommended clinical exposure at the 1.8 mg/day dose.
Mice were given subcutaneous doses of pasireotide at 0.5, 1.0, 2.5 mg/kg/day for 26 weeks and did not identify any carcinogenic potential. Mutagenesis Pasireotide was not genotoxic in a battery of in vitro assays (Ames mutation test in Salmonella and Escherichia coli and mutation test in human peripheral lymphocytes). Pasireotide was not genotoxic in an in vivo rat bone marrow nucleus test.
Impairment of Fertility Subcutaneous dosing at 0.1 mg/kg/day before mating and continuing into gestation in rats at exposures less than the human clinical exposure based on body surface area comparisons across species resulted in statistically significant increased implantation loss and decreased viable fetuses, corpora lutea, and implantation sites. Abnormal cycles or acyclicity were observed at 1 mg/kg/day (5-fold higher than the maximum therapeutic exposure based on surface area, comparisons across species).
