Clinical Study to Evaluate Z7200 Pharmacokinetics Profile

An Open-Label, Randomized, Five-Period Cross-over, Single-dose Study to Compare Pharmacokinetics Profiles of Z7200 Medium Strength and Symbicort Turbohaler, With and Without Charcoal Blockade in Healthy Volunteers.

• Status: Completed
• Phase: Phase 1

Summary

Brief Summary: The primary objective was: * to assess the bioequivalence of a single dose (two inhalations) of the test product compared to the reference product, with and without charcoal blockade. The secondary objectives were: * to assess the pharmacokinetic profile of budesonide and formoterol in plasma after a single dose (two inhalations) of the test product and the reference product, with and without charcoal blockade. * to assess the safety and tolerability of the test product and the reference product, with and without charcoal blockade.

Detailed description

This was a single center, open label, randomized, five-period crossover, single-dose study in healthy volunteers aged 18 to 45 years. A total of 90 volunteers were planned to be enrolled, with 9 subjects in each of the 10 treatment sequences. The study consisted of 5 treatment periods, each lasting approximately 48h, separated by a washout period of a minimum of 5 days. RS01 and/or Symbicort Turbohaler device use training was provided on Day -1 and Day 1 of each treatment period. Subjects were screened for eligibility to participate in the study -28 to -2 days prior to the first treatment period, and were randomized to one of 10 treatment sequences containing the following 5 treatment arms on Day 1 of the first treatment period: Treatment A: Z7200 without oral activated charcoal\* Treatment B1: Symbicort 1 without oral activated charcoal\* Treatment B2: Symbicort 2 without oral activated charcoal\* Treatment C: Z7200 with oral activated charcoal\*\* Treatment D: Symbicort with oral activated charcoal\*\* Subjects were admitted to the clinical unit at 8.00 on the morning of Day -1, and were dosed on the morning of Day 1 following an overnight fast (minimum of 8h). On Day 2, following collection of the 24-h PK blood sample, subjects were discharged. \* Subjects who received treatments A, B1 and B2 rinsed their mouth vigorously with 50 mL water for 3 to 5 sec immediately after the second inhalation. \*\* A charcoal blockade was used to prevent absorption from oropharyngeal and GI tract, in order to assess the pulmonary deposition of budesonide and formoterol, with periods performed without a charcoal blockade allowing the assessment of the total systemic exposure to the drug.
