Bioavailability of Infacort When Administered Onto Food Compared to Direct Oral Administration

Overview

This is a single centre, open-label, randomised, single dose, three-period, crossover study to evaluate the bioavailability of Infacort® administered as 'sprinkles' with soft food and yoghurt compared with direct administration to the back of the tongue in dexamethasone-suppressed healthy adult male subjects.

The study will comprise of a pre-study screen, followed by 3 treatment periods and a post-study follow-up.

Full Title of Study: “A Single Centre, Open-label, Randomised, Single Dose, Three-period, Crossover Study to Evaluate the Bioavailability of Infacort Administered as Sprinkles With Soft Food and Yoghurt Compared With Direct Administration to the Back of the Tongue in Dexamethasone-suppressed Healthy Adult Male Subjects”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Crossover Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: July 26, 2017

Interventions

  • Drug: Infacort
    • Immediate-release multiparticulate formulation of hydrocortisone.

Arms, Groups and Cohorts

  • Experimental: Infacort – Yoghurt
    • One single 5mg dose of Infacort will be sprinkled onto 5mL of yoghurt and swallowed within three minutes. This will be taken with 240mL of water.
  • Experimental: Infacort – Soft Food
    • One single 5mg dose of Infacort will be sprinkled onto 5mL of soft food (such as applesauce) and swallowed within three minutes. This will be taken with 240mL of water.
  • Active Comparator: Infacort – Dry Granules
    • One single 5mg dose of Infacort will be administered as dry granules to the back of the tongue and swallowed. This will be taken with 240mL of water.

Secondary Measures

  • Tmax of Infacort® administered as sprinkles with yoghurt and soft food compared to Infacort® administered as dry granules to the back of the tongue.
    • Time Frame: Up to 12 hours post-IMP administration
    • Tmax of Infacort® administered as sprinkles with yoghurt and soft food compared to Infacort® administered as dry granules to the back of the tongue.

Participating in This Clinical Trial

6. No clinically significant abnormalities in 12-lead ECG as defined by the Investigator.

7. No clinically significant deviation outside the normal ranges for blood pressure and heart rate measurements as defined by the Investigator (please refer to appendix 1 for normal ranges).

8. Subjects (unless anatomically sterile or where abstaining from sexual intercourse is in line with the preferred and usual lifestyle of the subject) and sexual partners must use 2 effective contraception methods during the trial and for 3 months after the last dose, for example:

  • Oral contraceptive + condom
  • Intra‐uterine device (IUD) + condom
  • Diaphragm with spermicide + condom

9. Subjects must be available to complete all three periods of the study and the follow-up visit.

10. Subjects must satisfy a medical examiner about their fitness to participate in the study.

11. Subjects must be able to read and understand the informed consent form and must provide written informed consent to participate in the study.

Exclusion Criteria

1. A clinically significant history of gastrointestinal disorder likely to influence drug absorption.

2. Receipt of any medication other than paracetamol within the 14 days prior to dosing (including topical steroids, high dose vitamins, dietary supplements or herbal remedies).

3. Evidence of renal, hepatic, central nervous system, respiratory, cardiovascular or metabolic dysfunction.

4. Receipt of any vaccination within the previous one month.

5. Presence of infections (systemic fungal and viral infections, acute bacterial infections).
