Brief Summary:


COVID-19 is a new disease caused by SARS-CoV-2 that was identified in 2019. Some people who get sick with COVID-19 become ill requiring hospitalization. There are some medicines that may help with recovery. Researchers want to see if a drug called fostamatinib may help people who are hospitalized with COVID-19.


To learn if fostamatinib is safe in patients who are hospitalized with COVID-19 and gain earlier insight into whether it improves outcomes.


Adults age 18 and older who are hospitalized with COVID-19.


Participants will be screened with a physical exam, including vital signs and weight. They will have a blood test and chest x-ray. They will have a COVID-19 test as a swab of either the back of the throat or the back of the nose. They will take a pregnancy test if needed.

Participants will be randomly assigned, to take either fostamatinib pills or a placebo twice daily for up to 14 days in addition to standard of care for COVID-19. If they can swallow, they will take the pills by mouth with water. If they cannot swallow or are on mechanical ventilation, the pills will be crushed, mixed with water, and given through a tube placed through the nostril, or placed in the mouth, down the esophagus, and into the stomach. Blood samples will be taken daily. Participants will return to the Clinical Center for safety follow-up visits. At these visits, they will have a physical exam and blood tests. If they cannot visit the Clinical Center, they will be contacted by phone or have a telehealth visit.

Participation will last for about two months

Coronavirus Disease 2019 Drug: Placebo Drug: fostamatinib Phase 2

Detailed Description:

Coronavirus Disease 2019 (COVID-19) is the disease caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). SARS-CoV-2 primarily infects the upper and lower respiratory tract and can lead to acute respiratory distress syndrome (ARDS) in a subset of patients with a known high mortality rate. Additionally, some patients develop other organ dysfunction including myocardial injury, acute kidney injury, shock along with endothelial dysfunction and subsequently micro and macrovascular thrombosis.

Much of the underlying pathology of SARS-CoV-2 is thought to be secondary to a dysregulated immune response and more recently a hypercoagulable state leading to immunothrombosis. Currently, two therapies have shown efficacy in large multicenter trials for the treatment of COVID-19, one of which is an antiviral (remdesivir) and the other is an immunosuppressant corticosteroid meant to dampen the immune response (dexamethasone).

Spleen tyrosine kinase (SYK) is a cytoplasmic tyrosine kinase involved in the intracellular signaling pathways of many different immune cells. In this pilot study we propose to use fostamatinib (an SYK inhibitor) as a targeted therapy for the immunological complications of hospitalized patients with COVID-19. The biological mechanisms by which SYK inhibition may improve outcomes in patients with COVID-19 include the inhibition of pro-inflammatory cytokines by monocytes and macrophages, decreased production of neutrophil extracellular traps (NETs) by neutrophils, and inhibition of platelet aggregation; three pathways that are mediated through Fc receptors (FcR) recognition of antigen-antibody complexes or activation of c-type lectin receptors (CLEC).

This is a randomized, double-blind, placebo-controlled trial of fostamatinib for the treatment of hospitalized patients with COVID-19.

We will randomly assign fostamatinib or matched placebo (1:1) to 60 eligible COVID-19 patients who are a 5 to 7 on the 8-point scale (requiring supplemental oxygen via nasal canula or noninvasive ventilation, requiring mechanical ventilation or extracorporeal membrane oxygenation).
