  Purpose

The purpose of this study is to assess the absolute bioavailability of an oral bilastine formulation (test drug) compared to the endovenous administration of an IV bilastine formulation (control drug) in healthy volunteers.


Condition Intervention Phase
Healthy
 Drug: Bilastine
 Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Bio-availability Study
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Basic Science
Official Title: Study to Assess Oral Bioavailability of Bilastine (Estudio de Biodisponibilidad Oral de Bilastina)

Primary Outcome Measures:
  • The area under the plasma concentration versus time curve from time zero to infinity (AUC 0-∞ ). [ Time Frame: 17 blood draws performed at: 0,25 - 0,5- 0,75 - 1 - 1,25 - 1,5 - 1,75 - 2 - 2,5 - 3 - 4 - 5 - 7 - 12 - 24 - 48 and 72 hours post administration. ] [ Designated as safety issue: No ]
    Bilastine bioavailability will be obtained from the oral AUC 0-∞ / endovenous AUC 0-∞ quotient.


Secondary Outcome Measures:
  • Additional pharmacokinetic variables: Cmax, AUC 0-t, tmax, Ae, CLr and t ½ [ Time Frame: 17 blood draws and urine collection during 72 hours post administration ] [ Designated as safety issue: No ]
    • Cmax: Maximum plasma concentration; the highest concentration observed during a dosage interval
    • tmax: The time that Cmax was observed
    • AUC 0-t: The area under the plasma concentration versus time curve from time zero to the last time point
    • Ae: amount of accumulated unaltered drug in urine till the last time point
    • Clr: Renal clearance
    • t ½: Elimination halflife

  • Safety and tolerability of a single dose administration of oral and endovenous bilastine [ Time Frame: A last Follow up visit will be performed 7 days after last drug intake ] [ Designated as safety issue: Yes ]
    Safety will be assessed during the study by monitoring adverse events (AEs), clinical laboratory test results (urinalysis, blood chemistry, and haematology), vital signs (including blood pressure, respiration, temperature, and heart rate, supine and standing), electrocardiogram (ECG) results, and abnormal findings upon physical examination.

Detailed Description:

Single centre, open label, cross-over, randomised, controlled, single dose study. The primary endpoint is the determination of plasma concentrations versus time (17 samples per subject at various time intervals after dosing) in order to assess the oral bioavailability of bilastine in healthy volunteers. Therefore the primary pharmacokinetic variable will be the area under the plasma concentration versus time curve from time zero to infinity (AUC 0-∞). Additionally the following pharmacokinetic variables will also be assessed: Cmax, AUC 0-t, tmax, Ae, Clr, t1/2. Additional objectives are to describe the safety and tolerability of a single administration of oral and endovenous bilastine in healthy volunteers.

Twelve healthy volunteers will be included. Each volunteer will take in random order one single dose of 20 mg oral bilastine and 10 mg IV bilastine with a minimum washout period of 14 days between them.

Bilastine plasma concentrations will be measured using a liquid chromatography/mass mass spectrometry (LC/MS/MS) micro method

Criteria

Inclusion Criteria:

  • Healthy volunteers of either sex aged from ≥ 18 to ≤ 35 years of age.
  • Body mass index between 19 and 29 Kg/m2.
  • Non smokers.
  • Judged to be in general good health based on medical history, physical examination and clinical laboratory tests.
  • Able to communicate well with the investigator and to comply with the requirements of the entire study.
  • Provision of written informed consent to participate.

Exclusion Criteria:

  • Pregnant or breast-feeding women or with a positive pregnancy test. Subjects who do not agree to use an adequate method of contraception during the study.
  • Intake of another investigational medication in another clinical study within 4 months prior to the first study drug intake.
