Summary

This is a randomized, double-blind, placebo-controlled study that will investigate the safety and clinical activity of a single intravenous (IV) dose of MHAA4549A in hospitalized patients requiring oxygen with severe influenza A in combination with oseltamivir versus placebo with oseltamivir. A Sponsor-supplied rapid influenza test and/or a local polymerase chain reaction (PCR) test must be used as an aid in the diagnosis of influenza A infection.

Clinical Details

Official title: A PHASE 2 RANDOMIZED, DOUBLE-BLIND PLACEBO-CONTROLLED TRIAL OF MHAA4549A, A MONOCLONAL ANTIBODY, IN COMBINATION WITH OSELTAMIVIR VERSUS OSELTAMIVIR FOR TREATMENT OF SEVERE INFLUENZA A INFECTION

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome:

Safety: (composite outcome measure): Incidence of adverse events and clinical laboratory abnormalities

Time to normalization of respiratory function, defined as the time to cessation of O2 support resulting in a stable SpO2 >95% for at least 24 hours

Secondary outcome:

Proportion of patients with clinical failure 24 hours post-infusion defined by progression to increased O2 requirement, progression to ICU, prolonged ventilation or O2 support >2 weeks or death

Time to clinical resolution of vital signs

All-cause mortality at Day 14, Day 30, Day 60

Duration of viral shedding in upper respiratory samples

Duration of hospital / intensive care unit (ICU) stay

Proportion of patients requiring antibiotics for respiratory infections during study

Proportion of patients with secondary complications of influenza

Duration of ventilation

All-cause readmission at Day 30 and at Day 60

Pharmacokinetics (composite outcome measure): parameters derived from serum concentrations of MHAA4549A: area under the concentration-time curve (AUC), maximum observed concentration (Cmax), clearance, half-life, and volume of distribution

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Men or women >/= 18 years of age on day of signing informed consent or obtaining

surrogate consent from an authorized representative

- Diagnosis of influenza A where one or both of the following are used as aid(s) in

diagnosis: a Sponsor-supplied rapid influenza test, a local molecular PCR test

- One of the following markers of severity within 24 hours of admission: requirement

for O2 supplementation to maintain SpO2 >92% or positive pressure ventilation

- A negative urine or serum pregnancy test for women of childbearing potential within 2

days prior to study treatment

- Patients of reproductive potential must agree to use acceptable contraceptive

measures as per the protocol as a minimum, and local guidelines, if more stringent Exclusion Criteria:

- Pregnant or lactating, or intending to become pregnant during the study

- Hypersensitivity to monoclonal antibodies or any constituents of study drug

- Hypersensitivity to the active substance or to any excipients of oseltamivir

- Investigational therapy within the 30 days prior to study treatment

- Received prior therapy with any anti-influenza monoclonal antibody therapy including

MHAA4549A 8 months prior to study treatment

- Current treatment (within 7 days of dosing) with amantadine or rimantidine

- Patients who have taken more than a total of 3 days (6 doses) of approved

anti-influenza therapy (i. e., oral oseltamivir, inhaled zanamivir, or oral ribavirin) in the period from onset of symptoms and prior to enrollment

- Admission > 48 hours prior to study treatment

- Onset of influenza symptoms > 5 days prior to study treatment

- Positive influenza B or influenza A + B infection within 2 weeks prior to study

treatment

- High probability of mortality in the next 48 hours as determined by the investigator

- Patient requiring home or baseline oxygenation therapy

- Patient with history of chronic lung disease resulting in baseline SpO2 < 95%

- Patient on chronic dose of corticosteroids exceeding 10 mg/day of prednisone or

equivalent steroid dose for a duration of greater than 14 days within 30 days of entry into study

- Patients with the following significant immune suppression: bone marrow or solid

organ transplant in the previous 12 months; cancer chemotherapy in the previous 12 months, HIV infection with most recent CD4 < 200 cells/mL, or other significant immune suppression as determined by the investigator in discussion with the Sponsor Medical Monitor or representative

- Patient on extracorporeal membrane oxygenation at time of randomization

- Any disease or condition that would, in the opinion of the site investigator or

Sponsor, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol
