Study summary

This is a single-dose study to evaluate the pharmacokinetics, safety, and tolerability of icatibant administered to adult Japanese subjects.

Read the detailed description

Icatibant has been studied for the treatment of acute attacks of hereditary angioedema (HAE), an autosomal dominant disorder characterized by recurrent and self-limiting episodes of edema of the skin, larynx, and gastrointestinal tract. The most serious manifestation of an HAE attack is laryngeal edema, causing obstruction of the upper airways that may lead to death by asphyxiation if undiagnosed and/or untreated.

Icatibant has been approved in over 40 countries around the world including the United States (US) and Europe for the treatment of acute attacks of hereditary angioedema (HAE) in adults. This study is being conducted to evaluate the safety and tolerability of icatibant in a Japanese population and to evaluate whether race/ethnicity impacts the pharmacokinetics of icatibant after single subcutaneous injection.

This is an open-label, single-arm study that will enroll at least 12 Japanese subjects (in order to have 12 subjects complete the study), age 18-55 years inclusive. All subjects will receive a single subcutaneous injection of 30mg icatibant. The study will be conducted at 1 site in the US. The study will consist of a Screening Period, a Treatment Period, and a Follow-Up Period.

What researchers measure

Primary outcomes

  1. Peak Plasma Concentration (Cmax) of Icatibant and Metabolites

    Cmax is a term that refers to the maximum (or peak) concentration that a drug achieves in the body after the drug has been administrated.

    Time frame: Over 48 hours post-dose

  2. Time to Peak Plasma Concentration (Tmax) of Icatibant and Metabolites

    Tmax is the time after administration of a drug when the maximum plasma concentration in the body is reached.

    Time frame: Over 48 hours post-dose

  3. Drug Concentration Half-Life (T1/2) of Icatibant and Metabolites

    The time it takes for the blood plasma concentration of a substance to halve.

    Time frame: Over 48 hours post-dose

  4. Area Under the Plasma Concentration-time Curve (AUC) From Time Zero to Infinity (AUCinf) of Icatibant and Metabolites

    AUCinf is the area under the plasma concentration versus time curve extrapolated from time 0 to infinity, calculated using the observed value of the last non-zero concentration. AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much and how long a drug stays in a body.

    Time frame: Over 48 hours post-dose

  5. Total Body Clearance (CL/F) of Icatibant

    The rate at which a drug is removed from the body.

    Time frame: Over 48 hours post-dose

  6. Area Under the Plasma Concentration-Time Curve From Time Zero to the Time of the Last Quantifiable Concentration (AUC0-t) of Icatibant and Metabolites

    AUC0-t is the area under the plasma concentration versus time curve extrapolated from time 0 to to the last quantifiable concentration. AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much and how long a drug stays in a body.

    Time frame: Over 48 hours post-dose

Secondary outcomes

  1. The Total Number of Treatment-Emergent Adverse Events

    Treatment-emergent adverse events (TEAEs) were those that started after the single dose of icatibant.

    Time frame: TEAEs were collected after the single dose of icatibant until follow up, 5-7 days after icatibant administration

  2. The Percentage of Subjects With Any Injection Site Reactions.

    Time frame: Over 48 hours post-dose

  3. Safety Evaluation Measured by Percentage of Subjects With Not Clinically Significant Abnormalities in ECG Results

    Time frame: Over 48 hours post-dose

  4. Change From Baseline in Diastolic Blood Pressure

    Time frame: Over 48 hours post-dose

  5. Change From Baseline in Systolic Blood Pressure

    Time frame: Over 48 hours post-dose

  6. Change From Baseline in Pulse Rate
