Study information

Scientific title


Study hypothesis

To assess the following:

Safety and tolerability of single and multiple doses of AM103 following oral administration.

1. Pharmacokinetics (PK) of AM103 after single and multiple doses.
2. Effects of AM103 on Pharmacodynamic (PD) markers: whole blood ionophore-stimulated leukotriene LTB4 and urinary LTE4 production.

Ethics approval

Patient information sheet


Healthy volunteers. Study is primarily relevant in asthma and allergic rhinitis.


AM103 orally or placebo
Single doses: 50, 150, 300, 600, 1000 mg
Multiple doses: Administered once daily for 11 days. The doses are: 150, 300 and 600 mg, with an additional group to be defined (after the prior doses have concluded).

Intervention type

Drug names

Primary outcome measure

1. Adverse events
2. Physical examinations
3. Vital signs
4. ECGs
5. Clinical laboratory values

Single Dose Study: Physical examination, vital signs, ECG, and clinical laboratory tests will be carried out on Day 4 (72 ± 4 hours, end-of study time point) after study drug administration.

Multiple Dose Study:

Vital signs will be assessed at the following timepoints:
Day 1: pre-dose, 1, 2, 4, 12, and 24 hours after study drug administration
Days 2-10: pre-dose, 2 and 12 hours after study drug administration
Day 11: pre-dose, 2, 12 and 24 hours after study drug administration

Physical examination, vital signs, ECG, and clinical laboratory tests will be carried out on Day 14 (72 ± 4 hours after the Day 11 dose).

ECGs will be carried out at the following timepoints:
Single Dose Phase: 2-4 hours after the study drug administration
Multiple Dose Phase: 2-4 hours after the first dose of study drug on Day 1 and 2-4 hours after study drug administration on Days 5 and 11.

Secondary outcome measures

1. Pharmacokinetics: Concentrations of AM103 in plasma samples will be determined by validated Liquid Chromatography/Mass Spectrometry (LCMS) methods.
2. Pharmacodynamics: Whole blood ionophore-stimulated leukotriene LTB4 and urinary LTE4 production to be assayed by Enzyme Linked Immunosorbent Assay (ELISA) and mass spectrometry, respectively.
