  Purpose

This randomized, open-label, multicenter phase 2 trial will assess the safety, efficacy, and pharmacokinetics (PK) of anti-influenza plasma in subjects with influenza A or B. Hospitalized subjects with influenza A or B that have either a low oxygen level or a high respiratory rate will be eligible for study participation. This study will enroll adults, children and pregnant women.

Arms Assigned Interventions
Experimental: Anti-Influenza Immune Plasma and Standard Care
Participants will receive plasma with high titer anti-influenza A or anti-influenza B antibodies in addition to standard care.
Biological: Anti-Influenza Immune Plasma
2 units of plasma with high titer anti-influenza A or anti-influenza B antibodies at baseline
Behavioral: Standard Care
Standard care for hospitalized people with influenza
Active Comparator: Standard Care
Participants will receive standard care.
Behavioral: Standard Care
Standard care for hospitalized people with influenza

Detailed Description:

Morbidity and mortality occur despite treatment with current antivirals. Circulating influenza H1N1 and H3N2 isolates are highly resistant to amantadine and rimantadine, whereas previous seasonal H1N1 isolates were highly resistant to oseltamivir. So there is concern that circulating influenza A/H1N1 2009 virus may also acquire oseltamivir resistance.

This randomized, open-label, multicenter phase 2 trial will assess the safety, efficacy, and pharmacokinetics (PK) of anti-influenza plasma in subjects with influenza. Hospitalized subjects with influenza at risk for severe disease (as defined in the inclusion criteria) will be eligible for study participation. This study will enroll adults, children and pregnant women.

Up to 40 sites in the United States will participate in this protocol. One hundred eligible subjects will be randomized in a 1:1 ratio to receive either 2 units (or pediatric equivalent) of anti-influenza immune plasma on Study Day 0 in addition to standard care or standard care alone (50 subjects receiving standard care alone; 50 subjects receiving anti-influenza immune plasma and standard care).

Subjects will be assessed on Study Day 0 (pre-dose), 30 minutes post-dose (plasma arm only), and on Study Days 1, 2, 4, 7, 14, and 28. All subjects will undergo a series of efficacy, safety, and PK (HAI) assessments during the study. Blood samples will be collected at each time point (except Day 1). Nasal and oropharyngeal swabs for influenza PCR will be obtained on Days 0,1,2,4 and 7.

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Diagnosis of influenza A or B prior to enrollment
  • Hospitalization for signs and symptoms of influenza (decision for hospitalization will be up to the individual treating clinician).
  • Abnormal respiratory status, defined as room air saturation of oxygen (SaO2) less than 93% or tachypnea (respiratory rate above normal)
  • Agree to the storage of specimens and data
  • ABO compatible plasma available on site or available within 24 hours after randomization with activity against locally circulating strains of influenza

Exclusion Criteria:

  • Receipt of non-licensed treatment for influenza within the last 2 weeks (or plans to receive any time during the study). This does not include licensed drugs at nonapproved doses, off-label indications, or drugs available under an Emergency Use Authorization (EUA).
  • Symptoms or signs of the acute influenza-like illness have occurred for more than 7 days prior to enrollment.
  • History of severe allergic reaction to blood products (as judged by the investigator).
  • Medical conditions for which receipt of 500 mL volume (or 8 mL/kg for pediatric patients) may be dangerous to the subject (e.g. decompensated congestive heart failure [CHF], etc.)
  • Clinical suspicion that etiology of illness is primarily bacterial
