Study summary

MITIGATE is a prospective, open-label, parallel-group, randomized, pragmatic clinical trial. The MITIGATE Study has been designed to evaluate the real-world clinical effectiveness of pre-treatment with icosapent ethyl (IPE), also known as Vascepa®, compared to usual standard of care to prevent and reduce the sequelae of laboratory-confirmed viral upper respiratory infection (URI)-related (i.e., COVID-19, influenza, and other known viral respiratory pathogens) morbidity and mortality in a high-risk cohort of adults with established atherosclerotic cardiovascular disease (ASCVD).

Read the detailed description

For the MITIGATE study, eligible members receiving care within Kaiser Permanente Northern California (KPNC) will be identified and screened electronically in a 1:10 intervention to control allocation (i.e., IPE vs. usual care) stratified by age and pre-existing respiratory status. Patients randomly assigned and enrolled into the intervention arm will be asked to take IPE (2 grams by mouth twice daily) for a minimum of 6 months and until study completion. Patients assigned to the control arm (i.e., usual care) will be passively followed only electronically via the electronic health record (EHR).

What researchers measure

Primary outcomes

  1. Rate of confirmed viral URIs

    Confirmed viral URIs (i.e., including recurrent events) (i.e., COVID-19, influenza, and other known viral respiratory pathogens) based on laboratory testing (i.e., FDA or locally-approved testing modalities)

    Time frame: 0-12 months

Secondary outcomes

  1. Percentage of patients with moderate or severe confirmed viral URIs

    Confirmed viral URIs (i.e., including recurrent events) (i.e., COVID-19, influenza, and other known viral respiratory pathogens) based on laboratory testing (i.e., FDA or locally-approved testing modalities) with an oxygen saturation \<94% on room air and/or requiring any form of supplemental oxygen.

    Time frame: 0-12 months

  2. Worst clinical status due to a confirmed viral URI

    At any point in time based on a 7-point ordinal scale (i.e., 1 = death, 2 = mechanically ventilated/extracorporeal membrane oxygenation, 3 = high flow supplemental oxygen, 4 = low flow supplemental oxygen, 5 = hospitalized with no supplemental oxygen requirements, 6 = urgent care or emergency department visit not leading to hospitalization, and 7 = no relevant clinical encounters)

    Time frame: 0-12 months

Other outcomes

  1. Percentage of participants who die due to any cause

    Time frame: 0-12 months

  2. Percentage of participants experiencing a major adverse cardiovascular event

    Death due to any cause, hospitalization for myocardial infarction, or hospitalization for ischemic stroke

    Time frame: 0-12 months

  3. Percentage of participants experiencing an expanded major adverse cardiovascular event

    Major adverse cardiovascular events, hospitalization for acute coronary syndrome, and coronary revascularization (i.e., percutaneous coronary intervention and/or coronary artery bypass graft)

    Time frame: 0-12 months

  4. Percentage of participants who are hospitalized for heart failure

    Time frame: 0-12 months

  5. Percentage of participants who are hospitalized for any reason

    Time frame: 0-12 months

  6. Percentage of participants who have an emergency department visit for any reason

    Time frame: 0-12 months
