Dosing in kidney impairment
Renal Impairment No dosage adjustment of SIGNIFOR in patients with impaired renal function is required [see Clinical Pharmacology] .
Dosing in liver impairment
Dosage 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] .

Important 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.
Drug interactions
Check pasireotide against a medication listLabel text (3 paragraphs)
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 )
7.1 Effects 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)] .
7.2 Effects 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.

8.1 Pregnancy 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…
