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...

- A trained health care professional mixes it and injects it into your buttock muscle, usually every 4 weeks. You don't give it yourself, and food doesn't matter.
- Diarrhea, nausea, belly pain, headache, tiredness, and hair loss are common. High blood sugar and gallstones are also common, so you'll be monitored.
- Call about extreme thirst or urination, fainting, a very slow or irregular heartbeat, severe belly pain or fever, yellowing skin, severe weakness, or greasy loose stools.

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.

( 2.6 )
2.1Recommended Baseline Evaluations Prior to Initiation of SIGNIFOR LAR Prior to the initiation of SIGNIFOR LAR, it is recommended that patients have the following baseline evaluations: Fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) [see Warnings and Precautions (5.1)] Liver tests [see Warnings and Precautions (5.3)] Electrocardiogram (ECG), serum potassium and serum magnesium levels [see Warnings and Precautions (5.2)] Patients with poorly controlled diabetes mellitus, who have inadequate glucose control, should have anti-diabetic therapy optimized prior to starting SIGNIFOR LAR [see Warnings and Precautions (5.1)] .
2.2Important Administration Instructions SIGNIFOR LAR must be reconstituted by a trained healthcare professional immediately before use. Illustrations on reconstitution are found in Instructions for Use [see Dosage and Administration (2.6)] . SIGNIFOR LAR must be inspected visually before use.
The suspension should appear free of foreign particulates and should be homogeneous after mixing. SIGNIFOR LAR must be administered by a trained healthcare professional only by intramuscular injection in the right or left gluteus immediately after reconstitution. SIGNIFOR LAR must never be administered intravenously.
2.3Recommended Initial Dose Acromegaly The recommended initial dose of SIGNIFOR LAR for the treatment of acromegaly is 40 mg administered by intramuscular injection once every 4 weeks (every 28 days) [see Dosage and Administration (2.6) ]. Cushing's Disease The recommended initial dose of SIGNIFOR LAR for the treatment of Cushing's disease is 10 mg administered by intramuscular injection once every 4 weeks (every 28 days) [see Dosage and Administration (2.6) ].
2.4Dose Adjustment and Monitoring Acromegaly The dose may be increased to a maximum of 60 mg for patients who have not normalized growth hormone (GH) and/or age and sex adjusted insulin-like growth factor-1 (IGF-1) levels after 3 months of treatment with SIGNIFOR LAR at 40 mg and who tolerate this dose. Management of SIGNIFOR LAR-related adverse reactions or over-response to treatment (age and sex adjusted IGF-1 less than the lower limit of normal) may require dose reduction. The dose may be decreased, either temporarily or permanently, by 20 mg decrements [see Warnings and Precautions (5)] .
Cushing's Disease Following 4 months of treatment with the initial dose of 10 mg once every 28 days, the dose may be increased for patients who have not normalized 24-hour urinary free cortisol (UFC) and who tolerate this dose, up to a maximum dose of 40 mg once every 28 days. Management of suspected adverse reactions or over-response to treatment (e.g., cortisol levels less than the lower limit of the normal range or in the low part of the normal range in patients with symptoms suggestive of adren… [Excerpted — this section continues on DailyMed.]

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hyperglycemia, Diabetes, and Ketoacidosis: Sometimes severe. Monitor glucose levels as clinically appropriate during therapy. Monitor glucose levels more frequently in the months that follow initiation or discontinuation of SIGNIFOR LAR therapy and following SIGNIFOR LAR dose adjustment.
Use anti-diabetic treatment if indicated.If ketoacidosis is suspected, discontinue SIGNIFOR LAR and promptly evaluate and treat the patient. ( 2.1 , 5.1 ) Bradycardia and QT Prolongation: Use with caution in at-risk patients; evaluate ECG and electrolytes prior to dosing and periodically while on treatment. ( 2.1 , 5.2 , 7.1 ) Liver Test Elevations: Evaluate liver enzyme tests prior to and during treatment.
( 2.1 , 5.3 ) Cholelithiasis and Complications of Cholelithiasis: Monitor periodically. Discontinue if complications of cholelithiasis are suspected. ( 5.4 ) Pituitary Hormone Deficiency(ies): Monitor for occurrence periodically and treat if clinically indicated.
( 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 ( 5.6 )
5.1Hyperglycemia, Diabetes, and Ketoacidosis SIGNIFOR LAR can cause increases in blood glucose levels which are sometimes severe. There have been postmarketing cases of ketoacidosis with SIGNIFOR LAR in patients with history of diabetes and in patients without history of diabetes. In the acromegalic patient study, 5 patients naïve to drug therapy treated with SIGNIFOR LAR (2 of whom were normoglycemic at baseline) and none in the active comparator group were hospitalized for hyperglycemia (blood glucose range 359-506 mg/dL).
Two additional patients who had received active comparator in the main trial and were switched to SIGNIFOR LAR in the extension trial, were hospitalized for elevated glucose levels while on SIGNIFOR LAR; one of those patients developed diabetic ketoacidosis. In the Cushing's disease study, 2 patients were hospitalized for elevated blood glucose. In clinical studies for acromegaly and Cushing's disease, SIGNIFOR LAR caused an increase in the incidence of diabetes and prediabetes.
A majority of patients, including those with normal glucose tolerance, prediabetes and diabetes, experienced increased glucose levels within the first 3 months of treatment [see Adverse Reactions (6.1) ]. In the drug-naïve acromegaly study, the prevalence of diabetes increased from 30% at baseline to 60% at Month 12. In the study evaluating acromegaly patients previously treated with somatostatin analogs, the prevalence of diabetes increased from 71% at baseline to 87% at Month 6 in patients treated with SIGNIFOR LAR 40 mg, and from 60% to 84% in patients treated with SIGNIFOR LAR 60 mg.
In the Cushing's disease study, the prevalence of diabetes increased from 40% at baseline to 56% at Month 12. Patients with poor baseline glycemic control are at higher risk of developing severe hyperglycemia. Assess FPG and HbA1c prior to starting treatment with SIGNIFOR LAR [see Dosage and Administration (2.1)] .
In patients with poorly controlled diabetes mellitus, optimize anti-diabetic treatment before SIGNIFOR LAR initiation. Monitor blood glucose weekly for the first 3 months after initiating SIGNIFOR LAR and the first 4- to 6 weeks after dose increases. Continue monitoring thereafter, as clinically appropriate.
Patients who develop significant hyperglycemia on SIGNIFOR LAR may require initiation of anti-diabetic treatment or adjustment in their current anti-diabetic treatment. The optimal treatment for the management of SIGNIFOR LAR-induced hyperglycemia is not known. If hyperglycemia cannot be controlled despite medical management, reduce the dose of SIGNIFOR LAR or discontinue SIGNIFOR LAR.
Assess FPG and HbA1c after SIGNIFOR LAR discontinuation, if indicated. Patients receiving ant… [Excerpted — this section continues on DailyMed.]

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. Drug-Naïve Patients With Acromegaly The data described in Table 1 are derived from an active-controlled trial in patients with acromegaly naïve to previous drug therapy [see Clinical Studies (14.1)] . The data reflect exposure of 178 patients with acromegaly to SIGNIFOR LAR for a mean duration of 43 weeks.
In the overall study population, 52% were female and the average age of patients was 45 years. Table 1 presents common adverse reactions associated with SIGNIFOR LAR in this study. These adverse reactions were not present at baseline or, if present, worsened from baseline and occurred in at least 5% of patients treated with SIGNIFOR LAR.
Table 1 – Adverse Reactions Occurring in Greater Than or Equal to 5% of Patients Exposed to SIGNIFOR LAR in Patients With Acromegaly Naïve to Drug Therapy a Diabetes mellitus includes the following PTs: diabetes mellitus and type 2 diabetes mellitus. b Sinus bradycardia includes the following PTs: bradycardia and sinus bradycardia. c Injection-site reaction related AEs includes the following PTs: injection-site pain, injection-site reaction, injection-site haematoma, injection-site pruritus, injection-site swelling, injection-site erythema.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Drugs that Prolong QT: Use with caution in patients who are at significant risk of developing QTc prolongation. ( 5.2 , 7.1 ) Cyclosporine: Consider additional monitoring. ( 7.2 ) Bromocriptine: Consider bromocriptine dose reduction. ( 7.2 )
7.1Effect of Other Drugs on SIGNIFOR LAR Drugs That Prolong QT Co-administration of drugs that prolong the QT interval with SIGNIFOR LAR may have additive effects on the prolongation of the QT interval. Monitoring effects on the QT interval at 21 days is recommended [see Warnings and Precautions (5.2)] .
7.2Effect of SIGNIFOR LAR on Other Drugs Cyclosporine Concomitant administration of cyclosporine with SIGNIFOR LAR may decrease the relative bioavailability of cyclosporine and, therefore, dose adjustment of cyclosporine to maintain therapeutic levels may be necessary. Bromocriptine Co-administration of SIGNIFOR LAR 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 )
8.1Pregnancy Risk Summary The limited data with SIGNIFOR LAR 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 a 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 mg/kg/day, 5 mg/kg/day, and 10 mg/kg/day subcutaneously throughout organogenesis, maternal toxicity was observed at all doses, including the lowest dose tested which had exposures 12 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 106 times the exposure in humans at the highest recommended dose of 60 mg SIGNIFOR LAR administered as an intramuscular injection once every 4 weeks. In embryo-fetal development studies in rabbits given 0.05 mg/kg/day, 1 mg/kg/day, 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 5 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 mg/kg/day, 5 mg/kg/day, and 10 mg/kg/day during gestation through lactation and weaning, maternal toxicity was observed at all doses including the lowest dose (9 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 LAR 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 LAR, and any potential adverse effects on the breastfed child from SIGNIFOR LAR 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 LAR have not been established in pediatric patients.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of SIGNIFOR LAR did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. 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 of concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE 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. Up-to-date information about the treatment of overdose can be obtained from a certified Regional Poison Center. In the event of an overdose, contact the National Capital Poison Center at 1-800-222-1222 or www.poison.org.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action SIGNIFOR LAR is an injectable cyclohexapeptide, somatostatin analog. Pasireotide exerts its pharmacological activity via binding to somatostatin receptors (SSTR). There are 5 known human somatostatin receptor subtypes: SSTR 1, 2, 3, 4, and 5.
These receptor subtypes are expressed in different tissues under normal physiological conditions. Somatostatin analogs bind to SSTRs with different potencies. Pasireotide binds with high affinity to 4 of the 5 SSTRs (see Table 4).
Table 4 – Binding Affinities of Somatostatin (SRIF-14) and Pasireotide to the Five Human SSTR Subtypes (SSTR 1-5) Results are the mean + SEM of IC 50 values expressed as nmol/l (nM). Compound SSTR1 SSTR2 SSTR3 SSTR4 SSTR5 Somatostatin (SRIF-14) 0.93 ± 0.12 0.15 ± 0.02 0.56 ± 0.17 1.5 ± 0.4 0.29 ±
0.04Pasireotide 9.3 ± 0.1 1.0 ± 0.1 1.5 ± 0.3 > 100 0.16 ± 0.01
12.2Pharmacodynamics Somatostatin receptors are expressed in many tissues including neuroendocrine tumors (e.g., growth hormone or adrenocorticotropic hormone secreting pituitary adenomas). Acromegaly Pasireotide binds to SSTR2 and SSTR5 subtype receptors which may be relevant for inhibition of GH secretion. In vivo studies show that SIGNIFOR LAR lowers GH and IGF-1 levels in patients with acromegaly.
Cushing's Disease 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. Cardiac Electrophysiology Individually corrected QT (QTcI) interval was evaluated in a randomized, blinded, crossover study in healthy subjects investigating pasireotide subcutaneous doses of 0.6 mg and 1.95 mg twice daily, respectively.
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 daily, and -15.2 (-16.5) bpm at 0.5 hours for pasireotide 1.95 mg twice daily. The predicted pasireotide peak concentration (25.8 ng/mL) following SIGNIFOR LAR 60-mg dose in acromegaly patients is similar to the observed peak concentration (24.3 mg/mL) of the subcutaneous SIGNIFOR 0.6 mg twice daily dose and below the observed peak concentration (80.6 ng/mL) of the subcutaneous SIGNIFOR 1.95 mg twice daily dose.
The predicted pasireotide peak concentration for the SIGNIFOR LAR dose of 40 mg in Cushing's disease patients is 14 ng/mL.
12.3Pharmacokinetics Pasireotide for intramuscular use is formulated as microspheres for long-acting release. After a single injection, the plasma pasireotide concentration shows an initial burst release on the injection day, followed by a dip from Day 2 to Day 7, then a slow increase to the maximum concentration around Day 21, and a slow declining phase over the next weeks, concomitant with the terminal degradation phase of the polymer matrix of the dosage form. Absorption and Distribution No studies have been conducted to evaluate the absolute bioavailability of pasireotide in humans.
Food effect is unlikely to occur since SIGNIFOR LAR is administered via a parenteral route. In healthy volunteers, pasireotide administered as SIGNIFOR LAR 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 the ADME (absorption, distribution, metabolism, excretion) of… [Excerpted — this section continues on DailyMed.]

Absorption and Distribution No studies have been conducted to evaluate the absolute bioavailability of pasireotide in humans.
Food effect is unlikely to occur since SIGNIFOR LAR is administered via a parenteral route. In healthy volunteers, pasireotide administered as SIGNIFOR LAR 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 the ADME (absorption, distribution, metabolism, excretion) of pasireotide is expected to be low. In clinical testing in healthy volunteers, P-gp inhibition did not affect the rate or extent of pasireotide availability [see Drug Interactions (7.1)] .
At therapeutic dose levels, pasireotide is not expected to be a substrate of BCRP (breast cancer resistance protein), OCT1 (organic cation transporter 1), or OATP (organic anion-transporting polypeptides) 1B1, 1B3, or 2B1. Elimination Metabolism and Excretion Pasireotide was shown to be highly metabolically stable in human liver and kidney microsomes. 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 GH 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 with subcutaneous SIGNIFOR with a single dose 0.6 mg, 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 apparent clearance (CL/F) of SIGNIFOR LAR in healthy volunteers is on average 4.5-8.5 L/hour. Steady-State Pharmacokinetics PK steady-state for SIGNIFOR LAR is achieved after 3 monthly doses. Following multiple intramuscular doses every 4 weeks (every 28 days), SIGNIFOR LAR demonstrates approximately dose-proportional PK exposures (steady-state trough; Ctrough, ss) in the dose range of 10 mg to 60 mg every 4 weeks.
Special Populations Population PK analyses of SIGNIFOR LAR suggest that race, gender, and body weight do not have clinically relevant influence on circulating levels of pasireotide. No dose adjustment is required for demographics. Pediatric Patients No studies have been performed in pediatric patients [see Use in Specific Populations (8.4)] .
Geriatric Patients Age is not a significant covariate in the population PK analysis. Therefore age is not expected to significantly impact circulating levels of pasireotide. Efficacy and safety data on patients older than 65 years are limited [see Use in Specific Populations (8.5)] .
Hepatic Impairment In a clinical study with a single subcutaneous dose of 600 µg 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 comparing with the control group, AUC inf was increased by 12%, 56%, and 42%; and C max was increased by 3%, 46%, and 33% respectively, in the mild, moderate,… [Excerpted — this section continues on DailyMed.]

🔬 Clinical Studies ▾
14 CLINICAL STUDIES
14.1Drug-Naïve Patients with Acromegaly A multicenter, randomized, double-blind study was conducted to assess the safety and efficacy of SIGNIFOR LAR in patients with active acromegaly. A total of 358 patients naïve to drugs used to treat acromegaly were randomized in a 1:1 ratio to SIGNIFOR LAR or another somatostatin analog active comparator. Randomization was stratified based on previous pituitary surgical status (e.g., at least 1 prior pituitary surgery versus no prior pituitary surgery).
In the overall study population, 52% were female and the average age of patients was 45 years. Sixty percent of patients were Caucasian, 23% Asian, 12% Other, 3% American Indian, and 2% were Black. Forty-two percent of patients had previous pituitary surgery, and 1 patient had a history of pituitary radiation therapy.
Median time between diagnosis and trial participation was 6 months. Median GH was 8.8 mcg/L (range: 0.8-200 mcg/L) and 10.1 mcg/L (range: 0.6-169.6 mcg/L) for SIGNIFOR LAR and active comparator, respectively at baseline. Median standardized IGF-1, defined as IGF-1 value divided by the ULN (i.e., fold above the ULN), was 2.9 (range: 0.9-6.9) and 2.9 (range: 0.8-7.3), for SIGNIFOR LAR and active comparator, respectively, at baseline.
The starting dose of SIGNIFOR LAR was 40 mg. Dose increase was allowed in both arms, at the discretion of investigators, after 3 and 6 months of treatment if mean GH was greater than or equal to 2.5 mcg/L and/or IGF-1 was greater than the ULN for age and sex. The maximum allowed dose for SIGNIFOR LAR was 60 mg.
The maximum dose of the active comparator was not used in this trial because the trial was multi-national and the maximum dose approved in the US was not approved in all participating countries. The efficacy endpoint was the proportion of patients with a mean GH level less than 2.5 mcg/L and a normal IGF-1 levels at month 12 (age- and sex-adjusted) (see Table 5, Figure 3, and Figure 4). The proportion of patients achieving this level of control was 31.3% and 19.2% for SIGNIFOR LAR and active comparator, respectively.
The changes in mean GH and IGF-1 levels by study visits in subjects with a measurement at these visits (observed cases) are shown in Figures 3 and 4.

Ninety-eight percent of patients treated with SIGNIFOR LAR had either a reduction or no change in tumor volume from baseline assessed by MRI at Month 12. The median (range) change in tumor volume was a reduction of 39.8% (-97.6% to 16.9%). Additionally, ring size and acromegaly symptoms score (i.e., headache, fatigue, perspiration, paresthesia, and osteoarthralgia) were followed.

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis A lifetime carcinogenicity study was conducted in rats and transgenic mice. Rats were given daily subcutaneous doses of pasireotide at 0.01 mg/kg/day, 0.05 mg/kg/day, and 0.3 mg/kg/day for 104 weeks. There were no drug-related tumors in rats at exposures up to 5-times higher than the maximum recommended clinical exposure of the pasireotide LAR 60 mg dose.
Mice were given subcutaneous doses of pasireotide at 0.5 mg/kg/day, 1 mg/kg/day, and 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 (4-fold higher than the maximum therapeutic exposure of pasireotide LAR based on surface area, comparisons across species).
