Trial overview

Official title: A randomized, double-blind, placebo controlled study to evaluate the safety, tolerability and clinical effect of oral danirixin (GSK1325756) in the treatment of healthy adults with acute, uncomplicated influenza (201682)
Trial description: Study 201682 is a Phase IIa, randomized, double blind, placebo-controlled four arm outpatient study evaluating the safety, tolerability and clinical effect of danirixin or danirixin + oseltamivir combination in comparison to placebo or oseltamivir twice daily for 5 days in otherwise healthy adults with laboratory confirmed influenza infection. Danirixin is a selective and reversible C-X-C Chemokine Receptor 2 (CXCR2) antagonist that inhibits neutrophil transmigration and activation to areas of inflammation. The study endpoints are intended to test the hypothesis that inhibition of neutrophil activation by approximately 50-60% (as previously measured by cluster of differentiation [CD11b] expression in response to chemokine [C-X-C motif] ligand 1 [CXCL1] stimulation ex vivo in human studies) will not impact safety parameters or worsen clinical manifestations of disease, disease-related events of interest, or viral load, and may possibly improve these parameters when administered within 48 hours of symptom onset. The aim of this exploratory study is to obtain data on the safety, tolerability and clinical effect of GSK1325756 (danirixin [DNX]) alone or in combination with oseltamivir (OSV) in otherwise healthy adults with acute, uncomplicated influenza prior to future evaluation in hospitalized patients with complicated influenza. The primary objective is to assess safety and tolerability of DNX with and without a neuraminidase inhibitor through the evaluation of AEs, SAEs, clinical laboratory tests, vital signs, and electrocardiogram (ECG) parameters. Safety assessments will also include an assessment of disease related events (DREs) of interest and associated antibiotic use. The Influenza Intensity and Impact Questionnaire (FluiiQ™) will be used in the study to document patient reported outcomes (PROs). The screening visit in Australia will be composed of a pre-screen for influenza infection with an influenza rapid antigen test followed by a screen for the remaining eligibility criteria for those subjects with a positive result on the influenza rapid antigen test. FluiiQ is trademark owned by Measured Solutions for Health Private Limited.
