Outcome Measures
Primary Outcomes (1)
Worsening based on the NIAID Ordinal scale
Proportion of subjects worsened at end of treatment (Day 29), as defined by categories 7 and 8 in the 8-point NIAID scale of disease severity. 1. Not hospitalized, no limitations on activities. 2. Not hospitalized, limitation on activities and/or requiring home oxygen\*. 3. Hospitalized, not requiring supplemental oxygen\* - no longer requires ongoing medical care. 4. Hospitalized, not requiring supplemental oxygen\* - requiring ongoing medical care (COVID-19 related or otherwise). 5. Hospitalized, requiring supplemental oxygen\*. 6. Hospitalized, on non-invasive ventilation or high-flow oxygen devices\*\*. 7. Hospitalized, on invasive mechanical ventilation or ECMO. 8. Death. * For subjects on chronic home O2 supplementation (pre-morbid state), supplemental O2 is defined as ≥ home O2 requirement. * Use of non-invasive ventilation for chronic conditions (eg, Obstructive sleep apnea \[OSA\]) is not applicable.

Study Arms (2)
PF-06650833 + Standard of Care treatment
ACTIVE COMPARATORSubjects randomized to the PF-06650833 arm of the study will receive 400 mg PF-06650833 (2 x 200 mg tablets) of the MR formulation orally QD under fasted conditions (preferably at least 4 hours after and 1.5 hours before a meal). Subjects who cannot take tablets PO will receive PF-06650833 200 mg IR suspension formulation every 6 hours (NG tube or OG tube, or equivalent). Subjects for whom concomitant administration of a strong inhibitor of CYP3A4 (eg, ritonavir) will have the dose reduced to either 200 mg MR or IR QD. All dosing of study drug will be in addition to current hospital SOC treatment that must include treatment targeting SARS-CoV-2.
Placebo + Standard of Care treatment
PLACEBO COMPARATORPlacebo will match the Active comparator in dosage form, dosage, frequency and duration.
Interventions
PF-06650833 is an investigational, highly potent and selective, reversible inhibitor of IRAK4. IRAK4 is a serine, threonine kinase that is a key intracellular signaling node downstream of the myddosome-associated Toll-Like Receptors (TLR) 1, 2, 4, 5, 6, 7, 8, 9 and 10, and the interleukin (IL)-1 family receptors (IL-1R, IL-18R and IL-33R) that mediate much of the innate immune signaling. As an inhibitor of TLR signaling, PF-06650833 targets a different part of the immune system from the Janus kinase (JAK) inhibitors. Given the partial redundancy of innate immune signaling through IRAK4-independent TLR pathways and the lack of direct suppression of T- and B-cell signaling, PF-06650833 is unlikely to lead to exaggerated immunosuppression.
Placebo will match the study drug in dose, formulation, route and frequency.
Eligibility Criteria
You may qualify if:
- Hospitalized adult male and female patients, including women of childbearing potential, at least 18 years of age, inclusive. Women of childbearing potential must agree to the protocol-specific contraception requirements.
- Participant (or legally authorized representative) capable of giving signed informed consent.
- Laboratory-confirmed novel coronavirus (SARS-CoV-2) infection.
- Evidence of pneumonia assessed by ALL of the following:
- Radiographic imaging (eg, chest x-ray, chest computed tomography \[CT\] scan, etc.); AND
- Clinical assessment (evidence of rales/crackles on exam); AND
- SpO2 ≤94% on room air.
- Evidence of increased inflammation as assessed by hsCRP \> ULN AND at least ONE of the following being \> ULN (as available):
- Ferritin;
- Procalcitonin;
- D-dimer;
- Fibrinogen;
- LDH;
- PT/PTT.
You may not qualify if:
- Other medical condition other than COVID-19 or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study, eg, acute coronary syndrome.
- Suspected or known active systemic bacterial, viral (except SARS-CoV2 infection) or fungal infections
- Active herpes zoster infection.
- Known active or latent tuberculosis (TB) or history of inadequately treated TB.
- Active hepatitis B or hepatitis C.
- Patients with positive hepatitis B surface antigen (HBsAg) will be excluded. Patients who are HBsAg negative but hepatitis B core antibody (HBcAb) positive will need a negative hepatitis B virus deoxyribonucleic acid (HBV DNA) to be allowed to enroll in the study; if the HBV DNA is positive, they will be not eligible.
- Patients with a positive test for hepatitis C virus (hepatitis C virus antibody; HCV Ab) will need a negative hepatitis C virus ribonucleic acid (HCV RNA; or negative HCV Ab test) and normal liver function (as assessed by liver transaminases and bilirubin within protocol-permitted limits, and no other evidence of compromised liver synthetic ability (eg, albumin and coagulation tests within protocol-permitted limits) to be allowed to enroll in the study, provided other eligibility criteria are met.
- Known history of human immunodeficiency virus (HIV) infection with a detectable viral load or CD4 count \<500 cells/mm3 (or patients for whom documentation of viral load or CD4 counts are not available) will be excluded; patients on highly active anti retroviral treatment, undetectable HIV viral load, and CD4 counts ≥500 cells/mm3 would be eligible).
- Active hematologic cancer.
- Metastatic or intractable cancer.
- Pre-existing neurodegenerative disease.
- Proven bacterial pneumonia, other serious infection, sepsis, and/septic shock.
- Requirement for mechanical ventilation, or extracorporeal membrane oxygenation.
- Severe hepatic impairment defined as Child-Pugh Class B or Class C at baseline.
- Severe renal impairment with an estimated glomerular filtration rate (eGFR) \<50 mL/min/1.73 m2.
