Phase III DAS181 Lower Tract PIV Infection in Immunocompromised Subjects (Substudy: DAS181 for COVID-19): RCT Study
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.
A Phase III Randomized Placebo-Controlled Study to Examine the Efficacy and Safety of DAS181 for the Treatment of Lower Respiratory Tract Parainfluenza Infection in Immunocompromised Subjects
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.

- Provides signed informed consent prior to the initiation of any screening or study-specific procedures
For COVID-19 sub study:
- Be ≥18 years of age
- Provide adequate medical history to permit accurate stratification (but health status may be healthy, high-risk conditions, or immunocompromised).
- Prior to SARS CoV 2 infection, has the ability to carry out self-care activities of daily living (basic ADL)

- Has laboratory-confirmation of the presence of SARS CoV 2 in the respiratory tract by at least one of the following samples
- Satisfy inclusion criteria #1, 4, 5, 6, 7 of the main study
You CAN'T join if...

- Subjects with Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), or
Alkaline Phosphatase (ALP) ≥3x ULN and Total Bilirubin (TBILI) ≥2x ULN Note: Subjects with ALT/AST/ALP ≥ 3x ULN AND TB ≥2x ULN that have been chronically stable (for >1 year on more than one assessments) due to known liver pathology including malignancy (primary or metastasis), chronic medications, transplantation, or chronic infection will not be excluded
- Female subjects breastfeeding or planning to breastfeed at any time through 30 days after the last dose of study drug
- Subjects taking any other investigational drug used to treat pulmonary infection.

- Requires vasopressors to maintain blood pressure
For COVID-19 sub study:
- Subjects requiring invasive mechanical, Bi-PAP or CPAP ventilation at randomization.
- 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).
