About this study

Official title: A Phase II, Global, Randomized Study to Evaluate the Efficacy and Safety of Danirixin (GSK1325756) Co-administered With a Standard-of-care Antiviral (Oseltamivir), in the Treatment of Adults Hospitalized With Influenza

Danirixin (DNX) is a novel, selective, and reversible antagonist of the C-X-C chemokine receptor (CXCR) 2 and has been shown to decrease neutrophil transmigration and activation to areas of inflammation. An intravenous (IV) formulation of DNX hydrobromide (HBr) is being developed as an anti-inflammatory agent for treatment of adults hospitalized with influenza (IFV). While early therapy with antivirals decreases severity and duration of symptoms of influenza, there are no drugs that have demonstrated clinical efficacy in randomized clinical trials in this population. Current treatment guidelines for hospitalized IFV recommend neuraminidase inhibitors as standard of care therapy. IFV studies in animals have demonstrated that therapeutic treatment with the combination of a CXCR2 antagonist and a neuraminidase inhibitor reduced lung neutrophils and showed trends for improvements in clinical scores, lung function and pathology with no evidence of worsening outcomes, including viral load. This Phase 2, randomized, double-blind (for IV DNX), placebo-controlled (for IV DNX) 3-arm study will be the first study to determine the efficacy and safety of IV DNX when co-administered (in all groups) with standard of care antiviral treatment (open-label oral oseltamivir [OSV]) in subjects hospitalized with IFV. The primary objective of the study is to assess the efficacy of treatment with IV DNX twice daily given with oral OSV compared to oral OSV twice daily on time to clinical response (TTCR). In this study, subjects will be randomized in a 2:2:1 ratio to 15 milligram (mg) free base equivalent (FBE) IV DNX, 50 mg FBE IV DNX, or matching placebo twice daily. All subjects will also receive open-label 75 mg oral OSV, twice daily (given as standard of care). The study treatment duration will be for up to 5 days. The investigator may elect to continue treatment with OSV after 5 days of study treatment. Follow up will continue until Day 45 for all subjects. The study will begin with enhanced safety monitoring in sentinel cohorts, leading to stepwise enrollment of subjects. Subjects will be enrolled based on increasing levels of renal impairment, and less severe hospitalized subjects will be enrolled prior to enrollment of critically ill subjects, as this is the first study conducted in the hospitalized population with severe IFV. Approximately 300 subjects are targeted to be enrolled in the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to Clinical Response (TTCR)

    The clinical response was defined as Hospital discharge due to clinical improvement OR normalization of temperature; and oxygen saturation; and respiratory status/heart rate/systolic blood pressure (normalization of 2 out of these 3 parameters). The clinical response based on vital signs/ventilation status required 24-hour confirmation. Considering 2-hour assessment window, the response confirmation period was 22 hours. Kaplan Meier estimates for the median of TTCR was provided. One participant had vital sign resolution at Baseline and was counted as having a clinical response but was not included in the Kaplan Meier Estimates. Influenza Positive Population (IPP) Population comprised of all participants in the Intent to Treat Exposed (ITT-E) Population with influenza infection (positive influenza Polymerase Chain Reaction [PCR] or culture at any time point) confirmed by central lab testing. Only those participants with data available at the indicated time point were analyzed.

    The clinical response was defined as Hospital discharge due to clinical improvement OR normalization of temperature; and oxygen saturation; and respiratory status/heart rate/systolic blood pressure (normalization of 2 out of these 3 parameters). The clinical response based on vital signs/ventilation status required 24-hour confirmation. Considering 2-hour assessment window, the response confirmation period was 22 hours. Percentage of participants with positive clinical response are presented.

    Measured: Up to 45 Days

  7. Percentage of Participants With Improved Respiratory Status Over Time

  13. Number of Participants Used Antibiotics for Complications of Influenza

    Complications of influenza such as bacterial pneumonia, pneumothorax, pleural effusion, acute respiratory distress syndrome (ARDS), myositis, encephalitis, myocarditis, and associated antibiotic use was recorded.

    Measured: Up to 45 Days

  15. Number of Participants With Any Non-serious Adverse Event (AE); Any Serious AE (SAE); Any AEs of Special Interest (AESIs)

    An AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention or event associated with liver injury and impaired liver function were categorized as SAE.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Danirixin 15 mg FBE, Danirixin 50 mg FBE and Oseltamivir 75 mg in people with Virus Diseases, run by GlaxoSmithKline at 8 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 30 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States, Romania, Russia, Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Jul 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to Clinical Response (TTCR) (time frame: Up to 45 Days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02927431, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
