Descriptive Information
Brief Title  ICMJE Novel Experimental COVID-19 Therapies Affecting Host Response
Official Title  ICMJE CONNECTS Master Protocol for Clinical Trials Targeting Macro-, Micro-immuno-thrombosis, Vascular Hyperinflammation, and Hypercoagulability and Renin-angiotensin-aldosterone System (RAAS) in Hospitalized Patients With COVID-19 (ACTIV-4 Host Tissue)
Brief Summary The overarching goal of the Master Protocol is to find effective strategies for inpatient management of patients with COVID-19. Therapeutic goals for patients hospitalized for COVID-19 include hastening recovery and preventing progression to critical illness, multiorgan failure, or death. Our objective is to determine whether modulating the host tissue response improves clinical outcomes among patients with COVID-19.
Detailed Description

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has resulted in a global pandemic. The clinical spectrum of COVID-19 infection is broad, encompassing asymptomatic infection, mild upper respiratory tract illness, and severe viral pneumonia with respiratory failure and death. Between 13 and 40% of patients become hospitalized, up to 30% of those hospitalized require admission for intensive care, and there is a 13% inpatient mortality rate. The reasons for hospitalization include respiratory support, as well as support for failure of other organs, including the heart and kidneys. The risk of thrombotic complications is increased, even when compared to other viral respiratory illnesses, such as influenza. While 82% of hospitalized patients with COVID-19 are ultimately discharged alive, median length of stay is 10-13 days.

Early work in treating COVID-19 has focused on preventing worsening of the initial clinical presentation to prevent hospitalization and disease progression to organ failure and death. Studies conducted under this Master Host Tissue Protocol are expected to extend our knowledge of how to manage patients who are hospitalized for COVID-19 illness. Our objective is to determine whether modulating the host tissue response improves clinical outcomes among patients with COVID-19. This Master Protocol is a randomized, placebo-controlled trial of agents targeting the host response in COVID-19 in hospitalized patients with hypoxemia. The Master Host Tissue Protocol is designed to be flexible in the number of study arms, the use of a single placebo group, and the stopping and adding of new therapies. Our primary outcome is oxygen free days through day 28. This is defined as days alive and without supplemental oxygen use during the first 28 days following randomization. Patients who die on or before day 28 are assigned -1 oxygen free days.

Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Phase 3
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:
Participants will be randomly allocated in a two-step process: 1) The participant will first be randomized in an m:1 ratio to receive an active study drug or placebo, where m represents the number of study drug arms for which the participant is eligible. 2) The participant will then be randomly assigned with equal probability to one of the study drug arms. Participants will receive the corresponding study drug or matching placebo.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description:
Which study drug arm the participant enters will be known to the research sites and the participants, but assignment to active versus placebo will be blinded. The randomized assignment, concealed from the research team, will be transmitted to the site pharmacy, who will provide study medication. The participant, treating clinicians, study personnel (other than the unblinded statistician who will prepare closed DSMB interim reports), and outcome assessors will all remain blinded to group assignment until after the database is locked and blinded analysis is completed.
