Overview
11 DESCRIPTION SAJAZIR (icatibant) is a synthetic decapeptide with five non-proteinogenic amino acids. The chemical structure of icatibant acetate is presented in Figure 1. Figure 1 Chemical Structure Chemical name: D-Arginyl-L-arginyl-L-prolyl-L[(4R)-4-hydroxyprolyl]-glycyl-L[3-(2-thienyl)alanyl]-L-seryl-D-(1,2,3,4-tetrahydroisoquinolin-3-ylcarbonyl)-L[(3aS,7aS)-octahydroindol-2-ylcarbonyl]-L-arginine, acetate salt SAJAZIR (icatibant) injection 30 mg/3ml (10 mg/mL) is provided as a sterile, isotonic, and buffered solution of icatibant acetate in a single-dose, prefilled syringe for subcutaneous administration. Each mL of the solution contains 10 mg of icatibant (free base) which is equivalent to 11.38 mg of icatibant acetate. Each prefilled syringe delivers 3 mL of solution equivalent to a 30 mg icatibant dose. The solution is clear and colorless. The solution also contains sodium chloride (isotonicity reagent), glacial acetic acid (pH adjuster), sodium hydroxide (pH adjuster) and water for injection with a pH of approximately 5.5. The solution does not contain preservatives. Pharmacological class: Icatibant is a bradykinin B2 receptor antagonist. Image
How to use
2 DOSAGE AND ADMINISTRATION 30 mg injected subcutaneously in the abdominal area. ( 2.1 ) If response is inadequate or symptoms recur, additional injections of 30 mg may be administered at intervals of at least 6 hours. ( 2.1 ) Do not administer more than 3 injections in 24 hours. ( 2.1 ) Patients may self-administer upon recognition of an HAE attack. ( 2.2 ) 2.1 Recommended Dosing The recommended dose of SAJAZIR is 30 mg administered by subcutaneous (SC) injection in the abdominal area. Additional doses may be administered at intervals of at least 6 hours if response is inadequate or if symptoms recur. No more than 3 doses may be administered in any 24 hour period. 2.2 Administration Instructions SAJAZIR should be inspected visually for particulate matter and discoloration prior to administration. The drug solution should be clear and colorless. Do not administer if the product contains particulates or is discolored. Attach the provided 25 gauge needle to the syringe hub and screw on securely. Do not use a different needle. Disinfect the injection site and administer SAJAZIR by subcutaneous injection over at least 30 seconds. Patients may self-administer SAJAZIR upon recognition of symptoms of an HAE attack after training under the guidance of a healthcare professional [see Patient Counseling Information ( 17 )] .
Side effects
The most commonly reported adverse reactions were injection site reactions, which occurred in almost all patients (97%) in clinical trials. Other common adverse reactions occurring in greater than 1% of patients included pyrexia, transaminase increase, dizziness, and rash. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Cycle Pharmaceuticals Ltd at 1-800-836-4380 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch 6.1 Clinical Trials Experience The safety of icatibant was evaluated in three controlled trials that included 223 patients who received icatibant injection 30 mg (n=113), placebo (n=75), or comparator (n=38). The mean age at study entry was 38 years (range 18 to 83 years), 64% were female, and 95% were white. The data described below represent adverse reactions observed from the two placebo-controlled trials, consisting of 77 patients who received icatibant injection at a dose of 30 mg SC, and 75 who received placebo. The most frequently reported adverse reactions (occurring in greater than 1% of patients and at a higher rate with icatibant injection versus placebo) are shown in Table 1. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Warnings
Important safety information
Laryngeal attacks: Following treatment of laryngeal attacks with SAJAZIR, advise patients to seek immediate medical attention. ( 5.1 ) 5.1 Laryngeal Attacks Given the potential for airway obstruction during acute laryngeal HAE attacks, patients should be advised to seek medical attention in an appropriate healthcare facility immediately in addition to treatment with SAJAZIR.
Interactions
Inhibitors Icatibant is a bradykinin B2 receptor antagonist and thereby has the potential to have a pharmacodynamic interaction with ACE inhibitors where icatibant may attenuate the antihypertensive effect of ACE inhibitors. Clinical trials to date have excluded subjects taking ACE inhibitors.
