Phase 2

Conditions
COVID-19
Interventions
Registration Number
NCT04348071
Lead Sponsor
University of Colorado, Denver
Brief Summary

This study plans to learn more about the effects of a medicine called ruxolitinib on the progression of COVID-19 (coronavirus disease of 2019), the medical condition caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Ruxolitinib is FDA-approved for the treatment of myelofibrosis, polycythemia vera, and graft-versus-host disease. This study intends to define the impact of ruxolitinib on the severity and progression of COVID-19. This drug might to lower the hyperinflammation caused by the virus, which would prevent damage to the lungs and possibly other organs.

The study will recruit patients who have been diagnosed with COVID-19.

The goal is to recruit 80 patients.

Detailed Description

This is an adaptive Phase 2/3 clinical trial, with a focus on the assessment of safety in the first 20 participants (Phase 2), followed by a much broader assessment of efficacy, while continuing to monitor safety, in an additional 60 participants (Phase 3, total participants across Phase 2/3 n=80). Both phases are single arm, open label, and occur at a single site at the University of Colorado Hospital (UCH). Data from participants in this study will be compared with data from other COVID-19 patients not receiving ruxolitinib. Study participants will receive 10 mg twice daily of ruxolitinib for 14 days and will be followed for up to 29 days.

  • lllness of any duration that meets each of the following:
  • Evidence of pneumonia, including radiographic infiltrates by imaging (chest x-ray, CT scan, etc.) or clinical assessment (rales/crackles on exam)
  • Requires supportive care, including non-invasive supplemental oxygen
  • Laboratory-confirmed SARS-CoV-2 infection as determined by PCR or other commercial or public health assay within 7 days of enrollment
  • Understands and agrees to comply with planned study procedures
  • Provides informed consent signed by study patient or legally acceptable representative
Exclusion Criteria
  • Absolute platelet counts are less than 75 x 10^9/L
  • Absolute neutrophil count is less than 0.5 x 10^9/L
  • Hemoglobin is less than 8 g/dL
  • Severe renal impairment defined by serum creatinine greater than 2 mg/dL or CrCl less than 30 mL/min
  • Treatment with other JAK inhibitors, strong CYP3A4 inhibitors, biologic disease-modifying anti-rheumatic drugs (DMARDs, including anti-IL-6 or anti-IL-6R antibodies), or potent immunosuppressants such as azathioprine and cyclosporine concurrently or within the past 5 days. Note: recent or concurrent treatment with hydroxychloroquine or chloroquine is allowable, as these are 'non-biologic' DMARDs with potential antiviral activity.
  • History of HIV infection and on active immunosuppressant therapy
  • Current hematological or solid organ malignancy and on active immunosuppressant therapy
  • Active tuberculosis (TB) infection or known or suspected systemic bacterial or fungal infection
  • Pregnancy or breast feeding
  • Known allergy to ruxolitinib
  • In the opinion of the investigator, they are unlikely to survive for >48 hours from screening
  • Any physical examination findings and/or history of any illness that, in the opinion of the investigator, might confound the results of the study or pose an additional risk to the patient by their participation in the study

Additional Exclusion Criteria for Phase 2 only:

  • Invasive oxygen supplementation, including mechanical ventilation and extracorporeal membrane oxygenation (ECMO)

GroupInterventionDescription
RuxolitinibRuxolitinibThis study is an Adaptive Phase 2/3 trial designed to test the safety (Phase 2) and efficacy (Phase 2 and 3) of ruxolitinib to treat COVID-19. Phase 2 consists of a single-arm, open-label assignment of 20 participants receiving 10 mg ruxolitinib twice daily for 14 days. Phase 3 consists of a single-arm, open-label assignment of 60 additional participants receiving ruxolitinib at the same dose. In both phases, participants will be monitored daily while hospitalized for 29 days, or until discharge, whichever occurs first. Participants who are discharged will be followed up with via phone on Day 15 and Day 29.
Primary Outcome Measures
NameTimeMethod
Phase 2: Cumulative incidence of Grade 3 and 4 adverse events (AEs)Day 0 (screening) through Day 29

Grade 3 AEs are defined as events that interrupt usual activities of daily living, or significantly affects clinical status, or may require intensive therapeutic intervention. Severe events are usually incapacitating. Grade 4 AEs are defined as events that are potentially life threatening. AEs will be collected and graded daily and cumulative incidence will be reported.

Phase 2: Changes in white blood cell count (CBC) through End of Study (EOS)Day through Day 29 or hospital discharge, whichever is first

Safety assessment via standard blood chemistry and metabolic panels will be performed daily as recommended by participant's physician as SOC. Mean changes from baseline to EOS will be reported.

Phase 2: Changes in glucose through End of Study (EOS)Day 1 through Day 29 or hospital discharge, whichever is first
Phase 2: Changes in platelets through Day 15Day 1 to Day 15
