Presence of significant comorbidity that, in the opinion of the investigator, predisposes the subject to mortality. Such conditions might include: a. New York Heart Association class IV Heart Failure b. Hepatic dysfunction (i.e., AST or ALT >3x upper limit of normal) c. Renal dysfunction (i.e., estimated glomerular filtration rate (eGFR) < 50mL/min) or receiving renal replacement therapy
Presence of septic shock at time of enrollment
Hemoglobin < 80 g/L
Evidence of neutropenia (i.e., absolute neutrophil count < 1000 cells/uL), lymphopenia (i.e., absolute lymphocyte count < 200 cells/uL) or thrombocytopenia (i.e.Platelets < 50×10^9/L)
Hypersensitivity to TD-0903 or its components, or to other JAK inhibitors
Treatment with anti-IL 6 (e.g., tocilizumab, sarilumab), anti-IL-6R antagonists (e.g., abatacept), JAK inhibitors (e.g., baricitinib, tofacitinib) supplemental interferon therapy, or tyrosine kinase inhibitors (e.g., erlotinib, gefinitib) in the past 30 days, or plans to receive a JAK inhibitor during the study period
Current treatment with conventional synthetic disease-modifying anti-rheumatic drugs (DMARDs)/immunosuppressive agents including:
1. Methotrexate, cyclosporine, mycophenolate, tacrolimus, penicillamine, or sulfasalazine within 2 weeks prior to enrollment
2. Azathioprine or cyclophosphamide within 12 weeks prior to enrollment
3. Monoclonal antibodies targeting B cells (e.g., rituximab) within 12 weeks prior to enrollment
4. Tumor necrosis factor-alpha (TNFα)) inhibitors within 4 weeks prior to enrollment
Participating in other clinical trials involving any other experimental treatment for COVID-19, except in the context of a single-arm antiviral or convalescent plasma compassionate-use protocol
Subjects with active or incompletely treated pulmonary tuberculosis, or known history of non-tuberculosis mycobacterium over past 12 months
Subject requires continuous oxygen supplementation for underlying cardio-respiratory history in the past 90 days
Body Mass Index ≥40 kg/m2
Receipt of live vaccine (i.e., live attenuated) in the 4 weeks prior to visit 1 or plans to receive a live vaccine (or live attenuated) during the study period. Note: Use of non-live (inactivated) vaccinations is allowed for all subjects
History of venous thromboembolism (VTE), deep venous thrombosis (DVT), Pulmonary Embolism (PE) or known hypercoagulable disorder (e.g., factor V Leiden, antiphospholipid antibody syndrome, protein C or S deficiency)

Primary Outcome Measures

Name	Time	Method
Part 2: Number of Respiratory Failure-free Days (RFDs) From Randomization to Day 28	Randomization to Day 28	An RFD was defined as a day that a participant was alive and did not require the use of any respiratory support (invasive mechanical ventilation, non-invasive positive pressure ventilation, high-flow oxygen devices, or oxygen supplementation) from randomization through Day 28. The number of RFDs was 0 for participants who used respiratory support for 28 days or longer or for participants who died on or before Day 28. A clinical status score of ≤ 4 on a given day was equivalent to an RFD. The clinical status categories and associated scores ranged from 1-8 where a higher score represented a worse outcome. A clinical status score of 4 was defined as a participant who was hospitalized, not requiring supplemental oxygen, but requiring ongoing medical care (whether or not related to COVID-19).

Secondary Outcome Measures

Name	Time	Method
Part 2: Change From Baseline in SaO2/FiO2 Ratio on Day 7	Baseline and Day 7	SaO2/FiO2 ratio was calculated as SaO2 divided by FiO2.
Part 2: Number of Participants Alive and Respiratory Failure-free on Day 28	Day 28	Defined as participants who were alive and did not require the use of any respiratory support (invasive mechanical ventilation, non-invasive positive pressure ventilation, high-flow oxygen devices, or oxygen supplementation) on Day 28.
Part 2: Number of Participants in Each Category of the 8-point Ordinal Clinical Status Scale on Days 7, 14, 21, and 28	Days 7, 14, 21 and 28	The clinical status categories and associated scores ranged from 1-8 where a higher score represented a worse outcome. The scale was as follows: * Score 1: Not hospitalized, no limitations on activities * Score 2: Not hospitalized, but with limitations on activities and/or requiring home oxygen * Score 3: Hospitalized, not requiring supplemental oxygen, and no longer requiring ongoing medical care * Score 4: Hospitalized, not requiring supplemental oxygen, but requiring ongoing medical care (whether or not related to COVID-19) * Score 5: Hospitalized, requiring supplemental oxygen * Score 6: Hospitalized, on non-invasive ventilation or high-flow oxygen devices * Score 7: Hospitalized, on invasive mechanical ventilation or extracorporeal membrane oxygenation * Score 8: Death
