RECRUITING
Not specified
Inclusion Criteria:
• At the time of randomization, requires supplemental oxygen ≥2 LPM due to hypoxemia.
• Immunocompromised, as defined by one or more of the following: * Received an autologous or allogeneic hematopoietic stem cell transplantation (HSCT) at any time in the past * Received a solid organ transplant at any time in the past * Has been or is currently being treated with chemotherapy for hematologic malignancies (e.g., leukemia, myeloma, lymphoma) and/or solid tumor malignancies (e.g., lung, breast, brain cancer) at any time in the past * Has an immunodeficiency due to congenital abnormality (only applicable to subjects age \< 18 years old) or pre-term birth (only applicable to subjects age ≤ 2 years old)
• Has, within 3 days prior to randomization, a confirmed LRTI with a sialic acid dependent respiratory virus
• If female, subject must meet one of the following conditions: * Not be of childbearing potential or * Be of childbearing potential and have a negative urine/serum pregnancy test and agrees to practice an acceptable method of contraception
• Non-vasectomized males are required to practice effective birth control methods
• Capable of understanding and complying with procedures as outlined in the protocol
• 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)
• Have lower respiratory tract infection (LRTI) confirmed by CT imaging, with or without contrast, to involve at least 2 lobes of the lung.
• 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
Exclusion Criteria:
• Subjects may not be on hospice care or, in the opinion of the investigator, have a low chance of survival during the first 10 days of treatment
• 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.
• Psychiatric or cognitive illness or recreational drug/alcohol use that, in the opinion of the principal investigator, would affect subject safety and/or compliance
• Subjects with known hypersensitivity to DAS181 and/or any of its components
• Subjects with severe sepsis due to either their baseline SAD-RV infection or a concurrent viral, bacterial, or fungal infection and meet at least one of the following criteria: * Has evidence of vital organ failure outside of the lung (e.g., liver, kidney) * 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).
• Subjects who are known HIV-positive (and not undetectable at most recent HIV RNA assessment)
• Subjects who are currently taking immunomodulating biologics (e.g, interferons, interleukin)
• 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
• Subjects meeting exclusion criteria #2, 3, 5 and 6 of the main study
