Purpose

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.

Inclusion Criteria

  1. Hospitalized for COVID-19 2. ≥18 years of age 3. SARS-CoV-2 infection, documented by: 1. a nucleic acid test (NAT) or equivalent testing within 3 days prior to randomization OR 2. documented by NAT or equivalent testing more than 3 days prior to randomization AND progressive disease suggestive of ongoing SARS-CoV-2 infection per the responsible investigator (For non-NAT tests, only those deemed with equivalent specificity to NAT by the protocol team will be allowed. A central list of allowed non- NAT tests is maintained in in the study protocol) 4. Hypoxemia, defined as SpO2 <92% on room air, new receipt of supplemental oxygen to maintain SpO2 ≥92%, or increased supplemental oxygen to maintain SpO2 ≥92% for a patient on chronic oxygen therapy 5. Symptoms or signs of acute COVID-19, defined as one or more of the following: 1. cough 2. reported or documented body temperature of 100.4o F or greater 3. shortness of breath 4. chest pain 5. infiltrates on chest imaging (x-ray, CT scan, lung ultrasound)

Exclusion Criteria

  1. History of sensitivity (including angioedema) or allergic reaction to medication targeting the RAAS system including study medications or other allergy in the opinion of the investigator that contraindicates participation 2. COVID-19 symptom onset >14 days prior to randomization 3. Hospitalized for >72 hours prior to randomization 4. Hemodynamic instability - defined as MAP < 65 mmHg at time of randomization confirmed on two measurements 5 minutes apart OR vasopressors at or above norepinephrine equivalent of 0.1 mcg/kg/min in prior 4 hours to maintain MAP > 65 mmHg 5. Pregnancy 6. Breastfeeding 7. Prisoners 8. End-stage renal disease (ESRD) on dialysis 9. Patient and/or clinical team is not pursuing full medical management (if a patient has a Do Not Resuscitate order that precludes chest compressions in the event of a cardiac arrest but is otherwise pursuing full medical management, he/she is eligible for this trial). 10. Known severe renal artery stenosis 11. Known significant left ventricular outflow obstruction, such as obstructive hypertrophic cardiomyopathy or severe aortic or mitral stenosis 12. Randomized in another trial evaluating RAAS modulation in the prior 30 days 13. The treating clinician expects inability to participate in study procedures or participation would not be in the best interests of the patient TRV027-specific exclusion criteria: Participants on Angiotensin receptor blockers (ARBs) will be excluded from this study arm. TXA127-specific exclusion criteria: eGFR < 30 mL/min/1.73m2

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.
Primary Purpose
Treatment
Masking
Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description
Which study 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.

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.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
