Brief summary

This 2-part study will be carried out on healthy elderly subjects to evaluate relative bioavailability of danirixin formulations. Part A will support the selection of the formulation and Part B will assess food effect, bioavailability and pharmacokinetic (PK) profile of selected formulation from Part A. Danirixin is currently administered with food, therefore the investigation of food effect for the selected formulation could potentially enable dosing without food. Approximately 16 subjects will be included in Part A and approximately 24 subjects will be included in Part B. Both parts will include a screening phase, treatment phase with in-between washout period and a follow-up phase.

Interventions

Danirixin is being developed as a potential anti-inflammatory agent for the treatment of chronic obstructive pulmonary disorder (COPD) and other inflammatory diseases and influenza. Danirixin reference (600 mg) or test formulation (475 or 600 mg or 600 mg with 5 percent HPMC) immediate release tablets will be administered by oral route in a cross-over manner.

DRUGOmeprazole

Omeprazole is used as an antacid. OMP 40 mg delayed-release capsule will be administered by oral route to randomized subjects.

Blood samples were collected at the indicated time points after administration of study treatment to investigate the PK profile of Danirixin. PK parameters were calculated by standard non-compartmental analysis using WinNonlin based on actual sampling times.

Time frame: Pre-dose and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 48 hours in Part 1

Population: PK population. Only those participants with data available at specified time points were analyzed
