Brief Summary:
This will be a phase 1a randomized, open label, multi-center study with approximately 24 subjects. All subjects will receive standard of care (SOC) per institutional guidelines for treatment of hospitalized patients with COVID-19 infection. In addition to SOC, the brequinar group will receive 5 daily doses of brequinar 100 mg.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Brequinar Other: Standard of Care Phase 1 Phase 2

Detailed Description:
This will be a phase 1a randomized, open label, multi-center study with approximately 24 subjects. All subjects will receive standard of care (SOC) per institutional guidelines for SARS-CoV-2 infection. Subjects will be randomly assigned in a 1:2 ratio to standard of care alone or standard of care plus brequinar. The brequinar group will receive 5 daily doses of brequinar 100 mg on Days 1 - 5. Physical examinations, vital signs, laboratory assessments, SARS-CoV-2 testing, and other observations will be conducted by experienced personnel throughout the study based on the Schedule of Events. Blood chemistry tests include blood urea nitrogen (BUN), creatinine, alkaline phosphatase (ALP), alanine amino transferase (ALT), aspartate amino transferase (AST), bilirubin, total protein, albumin, glucose, serum electrolytes (sodium, potassium, chloride, carbon dioxide/bicarbonate, and calcium), lactate dehydrogenase (LDH). Plasma will be collected for inflammatory markers such as D-dimer, ferritin, CRP, and ESR. Pro-inflammatory markers will be measured. Serum is to be collected for research purposes. Hematology tests include hemoglobin, hematocrit, complete blood count with full differential, and platelet count. Nasopharyngeal swabs for viral load will be collected Days 1, 3, 5, 7, and 15. Survival will be assessed through Day 29.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Willing and able to provide informed consent for the trial, written, electronic, verbal or other method deemed acceptable by the institution and IRB.
  2. 18 years of age or older and at least one of the following co-morbidities by subject history or present in the institution's electronic health record: hypertension, diabetes, chronic kidney disease, chronic obstructive pulmonary disease (COPD) or asthma, cardiovascular disease (coronary artery disease or congestive heart failure), liver cirrhosis, age > 65, BMI > 30.
  3. If discharged from the hospital prior to Study Day 15 or if follow up is needed for study drug-related adverse event, willing to go to an outpatient laboratory for a laboratory sample as well as a contact (phone call or other digital media) on Study Days 7 and 15 and contact only on Day 29.
  4. Laboratory-confirmed SARS-CoV-2 infection as determined by real time polymerase chain reaction (RT-PCR) or other FDA-cleared commercial or public health assay.
  5. Hospitalized (in patient with expected duration ≥ 24 hours)
  6. The effects of brequinar on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
