Pharmacokinetic data: DrugBank · CC BY-NC 4.0
Icatibant was approved by the FDA on August 25, 2011, and by the EMA in 2008 as a treatment for hereditary angioedema.[L49776][L49781] The FDA approval was based on positive results obtained from 3 double-blind, randomized, controlled clinical trials known as FAST 1, 2, and 3, where a median time to almost complete symptom relief was observed to be 8 hours compared to 36 hours for the placebo treatment.[L49776]

Known interactions with other medications. Always consult a healthcare professional.
Showing 50 of 786 interactions
In a pre- and post-natal development study in rats, delayed parturition was observed at subcutaneous doses 0.5 times the MRHD and higher, which resulted in deaths of dams at doses 2 times the MRHD and higher. Fetal death and early pup deaths were observed with doses 2 times the MRHD.
[L49756]
Two-year studies were conducted in CD1 mice and Wistar rats to assess the carcinogenic potential of icatibant. No evidence of tumorigenicity was observed in mice and rats at icatibant subcutaneous doses up to 15 mg/kg/day (twice per week) and 6 mg/kg/day (daily), respectively (approximately 10-fold and 6-fold greater than the MRHD on an AUC basis, respectively).
[L49756]
Icatibant tested negative for genotoxicity in the in vitro Ames bacterial reverse mutation test, in vitro Chinese hamster bone marrow chromosome aberration assay, and in vivo mouse micronucleus test.
[L49756]
Daily subcutaneous administration of icatibant to rats and dogs caused ovarian, uterine, and testicular atrophy/degeneration and adverse effects on the mammary and prostate glands.
In rats, testicular atrophy, reduced prostate gland secretion, decreased testosterone levels and degenerate corpora lutea occurred at doses greater than or equal to 3 mg/kg (approximately 5-fold greater than the MRHD in males and 2-fold greater than the MRHD in females on an AUC basis) and a decrease in developing ovarian follicles, mammary gland masculinization, and uterine atrophy occurred at doses greater than or equal to 10 mg/kg (approximately 6-fold greater than MRHD in females on an AUC basis). In dogs, reduced sperm counts and uterine atrophy occurred at doses greater than or equal to 1 mg/kg (approximately 2-fold greater than the MRHD on an AUC basis). Atrophy of the testes and prostate with decreased testosterone levels, decreased ovary size and decreased number of developing follicles occurred at a dose of 10 mg/kg (approximately 30-fold greater than the MRHD in males and 15-fold greater than at the MRHD in females on an AUC basis).
[L49756]
In contrast to the effects of daily icatibant administration, toxicity to the ovary, uterus, testis, mammary gland, and prostate did not occur in dogs treated twice a week for 9 months.
AUC exposures from a dose of 3 mg/kg in these dogs were 5- and 3-fold the MRHD exposures in men and women, respectively. Sperm counts and testosterone remained unaffected over the course of the study in male dogs dosed twice a week.
[L49756]
Reproduction studies in male mice and rats with daily administration of icatibant found no effects on fertility or reproductive performance with intravenous doses up to 81 mg/kg (approximately 5-fold greater than the MRHD on a mg/m2 basis) or subcutaneous doses up to 10 mg/kg (approximately 11-fold greater than the MRHD on an AUC basis), respectively.
[L49756]
In a clinical study evaluating a 90 mg dose (30 mg in each of 3 subcutaneous sites), the adverse event profile was similar to that seen with 30 mg administered in a single subcutaneous site.
[L49756]
In another clinical study, a dose of 3.2 mg/kg administered intravenously (approximately 8 times the therapeutic dose for HAE) caused erythema, itching, and hypotension in healthy subjects. No therapeutic intervention was necessary.
[L49756]
The effect of icatibant 30 and 90 mg following a single subcutaneous injection on QTc interval was evaluated in a randomized, placebo-, and active-controlled (moxifloxacin 400 mg) four-period crossover thorough QT study in 72 healthy subjects. In a study with demonstrated ability to detect small effects, the upper bound of the one-sided 95% confidence interval for the largest placebo-adjusted, baseline-corrected QTc based on individual correction method (QTcI) was below 10 ms, the threshold for regulatory concern. The dose of 90 mg is adequate to represent the high-exposure clinical scenario.[L49756]
How the body processes this drug — absorption, distribution, metabolism, and elimination
Icatibant did not accumulate following multiple doses.
[L49756]
The pharmacokinetics of icatibant have been characterized in studies using both intravenous and subcutaneous administration to healthy subjects and patients. The pharmacokinetic profile of icatibant in patients with HAE is similar to that in healthy subjects.
[L49756]
The absolute bioavailability of icatibant following a 30 mg subcutaneous dose is approximately 97%. Following subcutaneous administration of a single 30 mg dose of icatibant to healthy subjects (N=96), a mean (± standard deviation) maximum plasma concentration (Cmax) of 974 ± 280 ng/mL was observed after approximately 0.75 hours.
The mean area under the concentration-time curve (AUC0-∞) after a single 30 mg dose was 2165 ± 568 ng·hr/mL, with no evidence of accumulation of icatibant following three 30 mg doses administered 6 hours apart.
