Read the detailed description

This protocol will seek to enroll adult otherwise healthy subjects presenting with influenza-like illness (ILI). Subjects will enter the study based on listed inclusion/exclusion criteria, including a positive diagnostic test for influenza virus (IFV).

Based upon a Rapid Diagnostic Test of IFV, subjects will be randomized into one of three groups: a single dose DAS181 10 mg group, a multiple dose DAS181 10 mg, 10 mg, 10 mg dose group or a placebo group.

The full analysis set will include subjects with confirmed influenza as documented with Rapid Diagnostic Testing. The set will be used for activity analysis and will include all randomized subjects with baseline and treatment data. Study staff may visit subjects outside the clinic. Per protocol, the safety analysis sets are described below in Statistical Methods.

Peripheral venous blood samples for pharmacokinetic (PK) and immunogenic analysis of DAS181 will be obtained on 10 subjects enrolled in each study arm.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing DAS181 dry powder, formulation F02 and Respitose ML006 (DMV-Fonterra) in people with Influenza, run by Ansun Biopharma, Inc. at 42 sites in United States.

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 12 inclusion and 23 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: finished, as of the sponsor's last update on 8 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 42 sites in United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Level of influenza viral load as Area Under the Curve at Day 5 (AUC0 d5) as measured by a) quantitative polymerase chain reaction (quantitative PCR) and b) 50% tissue culture infectious dose (TCID50) in cell culture (time frame: 28 days). The study lists 2 primary outcomes in all. 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 NCT01037205, 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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2014.
