shortness of breath or hypoxia defined by a ratio of partial pressure of arterial oxygen to the percentage of inspired oxygen (pao2/fio2) ≤ 300 mmhg or signs of serious lower airway disease. signs or symptoms of acute respiratory distress syndrome (ards), systemic inflammatory response syndrome (sirs)/shock, or cardiac failure; or need for supplemental oxygen. inflammatory markers (c-reactive protein [crp], lactate dehydrogenase [ldh], d-dimer, ferritin, and il-6) > 1.5 × upper limit of normal (uln). assessed by the investigator to be unable or unwilling to comply with the requirements of the protocol. pregnant and nursing women. a negative serum or urine pregnancy test during screening prior to the first dose must be documented before n-803 is administered to a female subject of child-bearing potential.
