Clinical Trial Summary

This study will seek to enroll immunocompromised patients with Lower Tract parainfluenza infection. It also contains a sub-study to enroll patients with severe COVID-19.

Description:

Eligible subjects (i.e., those meeting the Inclusion / Exclusion criteria) will be enrolled in one of four cohorts based on the following criteria: Cohort 1: All eligible subjects in the PoI who are ≥18 year old subjects with a PIV infection and meet all of the following criteria: 1.1 Meet criteria for being severely immunocompromised 1.2 Prior to the onset of PIV infection, had no ongoing need for oxygen therapy due to a chronic respiratory condition (e.g., COPD, sleep apnea) and are assessed as acutely hypoxemic due to their PIV infection 1.3 At the time of randomization are not on mechanical, bi-level or continuous positive airway pressure (Bi-PAP or CPAP) ventilation 1.4 Have no known concurrent respiratory viral coinfection(s) Cohort 2: All eligible subjects in the PoI who are ≥18 year old with a PIV infection (including those with PIV and another SAD-RV) who do not meet one or more of the listed criteria for Cohort 1. Cohort 3: All eligible subjects in the PoI who are <18 year old subjects with a PIV infection (including those with PIV and another concurrent SAD-RV). There is no lower age limit for this cohort. Cohort 4: All eligible subjects in the PoI with a respiratory infection due to any SAD-RV infection except PIV. Eligible subjects with both PIV and an additional concurrent SAD-RV, will be enrolled for either Cohorts 2 or 3 depending on their age. There is no lower age limit for this cohort. Sub-Study: Patients with Severe COVID-19

For COVID-19 sub study:

1. Subjects requiring invasive mechanical, Bi-PAP or CPAP ventilation at randomization.

2. Subjects receiving any other investigational or empiric treatment for SARS-2-CoV (either as part of a clinical trial or under emergency approval (approved agents for the management of symptoms, e.g., fever, are permitted).

3. Subjects who are known HIV-positive (and not undetectable at most recent HIV RNA assessment)

4. Subjects who are currently taking immunomodulating biologics (e.g, interferons, interleukin)

5. Subjects with severe sepsis due to either their SARS-CoV-2 infection or a concurrent viral, bacterial, or fungal infection and meeting at least one of the following

criteria:

• Have evidence of vital organ failure outside of the lung (e.g., liver, kidney)
• Require vasopressors to maintain blood pressure

6. Subjects meeting exclusion criteria #2, 3, 5 and 6 of the main study
