Boxed warning
WARNING: ANAPHYLAXIS Anaphylaxis has been reported after administration of KALBITOR. Because of the risk of anaphylaxis, KALBITOR should only be administered by a healthcare professional with appropriate medical support to manage anaphylaxis and hereditary angioedema. Healthcare professionals should be aware of the similarity of symptoms between hypersensitivity reactions and hereditary angioedema and patients should be monitored closely. Do not administer KALBITOR to patients with known clinical hypersensitivity to KALBITOR.

Administration Instructions KALBITOR should only be administered by a healthcare professional with appropriate medical support to manage anaphylaxis and hereditary angioedema. KALBITOR should be refrigerated and protected from the light. KALBITOR is a clear, colorless liquid; visually inspect each vial for particulate matter and discoloration prior to administration.
If there is particulate matter or discoloration, the vial should not be used. Using aseptic technique, withdraw 1 mL (10 mg) of KALBITOR from the vial using a large bore needle. Change the needle on the syringe to a needle suitable for subcutaneous injection. The recommended needle size is 27 gauge. Inject KALBITOR into the skin of the abdomen, thigh, or upper arm.
Repeat the procedure for each of the 3 vials comprising the KALBITOR dose. The injection site for each of the injections may be in the same or in different anatomic locations (abdomen, thigh, upper arm). There is no need for site rotation. Injection sites should be separated by at least 2 inches (5 cm) and away from the anatomical site of attack.
The same instructions apply to an additional dose administered within 24 hours. Different injection sites or the same anatomical location (as used for the first administration) may be used.

Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary The available data from the pharmacovigilance database for KALBITOR have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. In an animal reproduction study, increased early fetal deaths resulting in decreased live fetuses were observed in rats following treatment during the period of organogenesis at an intravenous dose approximately 1.6 times the maximum recommended human dose (MRHD) in the presence of maternal toxicity.
There were no effects on embryofetal survival or structural abnormalities in rats and rabbits following treatment during the period of organogenesis with intravenous doses up to approximately 1.1 and 6 times the MRHD, respectively, or rats treated with subcutaneous doses up to 2.4 times the MRHD. In a pre- and post-natal development study with rats, there were no effects on pup survival and development with subcutaneous doses up to approximately 2.7 times the MRHD. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S.
general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In an embryofetal development study with rats, ecallantide administered by the intravenous route during the period of organogenesis from gestation days 7 to 17 at a dose approximately 1.6 times the MRHD (on a mg/m 2 basis at a maternal intravenous dose of 15 mg/kg/day) caused increased numbers of early resorptions and percentages of resorbed conceptuses per litter resulting in decreased numbers of live fetuses in the presence of mild maternal toxicity.
No effects on embryofetal survival or structural abnormalities were observed in rats with intravenous doses up to approximately 1.1 times the MRHD (on a mg/m 2 basis with maternal intravenous dose of 10 mg/kg/day). In an embryofetal development study with rats, ecallantide administered by the subcutaneous route during the period of organogenesis from gestation days 7 to 17 at doses up to approximately 2.4 times the MRHD (on an AUC basis with maternal subcutaneous doses up to 20 mg/kg/day) had no effects on embryofetal survival or structural abnormalities.
In an embryofetal development study with rabbits, ecallantide administered by the intravenous route during the period of organogenesis from gestation days 7 to 19 at doses up to approximately 6 times…
Breastfeeding (LactMed)
No information is available on the use of ecallantide during breastfeeding. Because ecallantide is a large protein molecule with a molecular weight of about 7,000 Da, the amount in milk is likely to be very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract. Until more data become available, ecallantide should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant.
