Purpose

The goal of this project is to rapidly screen promising agents, in the setting of an adaptive platform trial, for treatment of critically ill COVID-19 patients. In this phase 2 platform design, agents will be identified with a signal suggesting a big impact on reducing mortality and the need for, as well as duration, of mechanical ventilation.

Remdesivir plus standard of care
See the Full EUA Prescribing Information for complete dosage, administration, and preparation instructions. Remdesivir is available as a concentrated solution. The recommended dose for adults weighing 40 kg and higher is a single loading dose of 200 mg on Day 1 followed by once- daily maintenance doses of 100 mg from Day 2. The optimal duration of treatment for COVID-19 is unknown. For patients requiring invasive mechanical ventilation and/or extracorporeal membrane oxygenation (ECMO), the recommended total treatment duration is 10 days. For patients not requiring invasive mechanical ventilation and/or ECMO, the recommended total treatment duration is 5 days. If a patient does not demonstrate clinical improvement, treatment may be extended for up to 5 additional days for a total treatment duration of up to 10 days. Administer remdesivir via IV infusion over 30 to 120 minutes.

Detailed Description

This platform trial will provide access to repurposed and investigational agents for critically ill patients infected with SARS-CoV-2 who have severe or life-threatening COVID-19. Any critically ill patient with known or presumed COVID-19 will be automatically entered into the screening phase of the trial until SARS-CoV-2 infection is confirmed. Basic data will be assembled for each patient (such as ventilatory status and survival). All patients who start high-flow oxygen (WHO COVID-19 level 5; > 6L oxygen by nasal prongs or mask) will be entered in an observational registry which will only require extraction of medical record data. Registry participants will be asked to sign a consent form for the backbone treatment and a specific investigational agent arm to which they are assigned. The primary endpoint will be time to recover to a durable level 4 (or less) on the WHO COVID-19 ordinal scale for clinical improvement. For this trial, a durable level 4 is defined as at least 48 hours at COVID level 4 or less (nasal prongs oxygen) without returning to high flow oxygen or intubation. Acute care facility resource utilization will be automatically calculated (total length of stay in a critical care setting, days intubated, and survival). Any change in status, including intubation, extubation, death or discharge, will be recorded and verified by the attending physician. Patients will be evaluated based on their initial status (ventilation at entry vs. high flow oxygen). Exploratory biomarkers will be evaluated over time (ARDS phenotypes and other proposed markers) to facilitate clinical learning. The trial will begin enrollment with two investigational agents and quickly increase to four study arms as the pace of enrollment increases. The anticipated accrual will be 50 patients per week. The maximum number of participants assigned to an arm without graduation will be 125 patients. Agents can be dropped for futility after enrollment of 50 patients. It is anticipated that 10 investigational agents can be evaluated in the span of 4-6 months, depending on the time course of COVID-19 infections across the US. As the trial proceeds and a better understanding of the underlying mechanisms of the COVID-19 illness emerges, expanded biomarker and data collection can be added as needed to further elucidate how agents are or are not working. The study design features comparison of investigational agent efficacy using a Bayesian design, which will allow the detection of strong efficacy signals with the fewest possible patients. Initially the control will be patients given current standard of care (supportive care for ARDS, including lung protective ventilation and remdesivir as backbone therapy). As other treatments (for example, anticoagulation) become part of standard supportive care across sites, these will be added to the backbone therapy. If an agent meets the threshold for graduation the company leadership will be informed as will the FDA. The arm with the graduated agent will cease to enroll, allowing a new arm with a different investigational agent to be added. Information about agents disposition will be as follows: Every trial participant will have blood collected at trial enrollment, day 3, and day 7 for pre-specified biomarker and DNA and RNA analysis. Additional biomarkers can be added as the trial proceeds. Patient outcomes will also be evaluated on the basis of whether patients are ventilated initially or not.
