Study type Participant information sheet
Scientific titleAn exploratory, randomised, open-label, two-period, crossover study in healthy subjects to evaluate the effect of ketoconazole on the pharmacokinetics of SMP-028
Study objectivesPrimary aim:
To assess the effects of administration of the CYP3A4 inhibitor, ketoconazole, on the single dose pharmacokinetic (PK) profile of SMP-028 in healthy subjects.

Secondary aim:
To assess the safety and tolerability of SMP-028 when co-administered with the CYP3A4 inhibitor, ketoconazole.
Ethics approval(s)Capenhurst Independent Research Ethics Committee, 16/03/2010
Health condition(s) or problem(s) studiedAsthma
InterventionSubjects will be randomised (in a 1:1 ratio) into one of two treatment sequences (Treatment A followed by Treatment B or Treatment B followed by Treatment A):
Treatment A consists of Ketoconazole 400 mg daily, administered orally twice a day on Days 1 to 7 followed by a single oral dose of SMP-028 20 mg on the morning of Day 5.
Treatment B consists of a single dose of SMP-028 20 mg on Day 1.
Subjects will be followed up for 8 days after dosing in Treatment A and 4 days in Treatment B.
Intervention typeDrug
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Ketoconazole, SMP-028
Primary outcome measure(s)

Pharmacokinetics:
1. Primary endpoints:
Comparative SMP-028 exposure between treatment periods (AUC[0-∞] and C[max]) over 72 hours
2. Secondary endpoints:
Comparative SMP-028 exposure between treatment periods (other pharmacokinetic parameters), and exposure levels of the metabolites of SMP-028 over 72 hours

Key secondary outcome measure(s)

Safety endpoints:
1. The proportion of subjects with adverse events (AEs)
2. Changes in standard laboratory safety tests
2.1. haematology
2.2. clinical chemistry
2.3. urinalysis
3. Concomitant medication review
4. Vital signs
5. Complete physical examinations
6. 12-lead ECG
