Clinical Trial Summary
In a randomized, double-blind, placebo-controlled, multi-center, Phase 2-like,
investigator-directed trial, hospitalized adult patients with laboratory confirmed SARS-CoV-2
infection meeting inclusion and exclusion criteria, will be provided information on the
trial, offered enrollment, and if informed consent provided, enrolled randomly in a 2:1 ratio
to one of two groups: Group 1 standard care and losartan or Group 2 standard care and
placebo. Patients will be followed for up to 60 days, with data collected to quantify the
NCOSS over time (the primary objective), and for the trial's secondary objectives (see
outcome measurements below).
Description:
Although a number of therapeutics have been utilized by clinicians to treat hospitalized
patients with COVID-19, none were systematically evaluated in clinical trials at the time of
the outset of this RCT (COVID MED). Since then, dexamethasone has been shown to decrease
mortality and remdesivir to possibly decrease hospital LOS in the RECOVERY and ACTT-II trials
and others. The initial iteration of this protocol included 4 arms, hydroxychloroquine,
lopinavir/ritonavir, losartan, and placebo based on suggestive efficacy and safety and
widespread empiric use. The current iteration of COVID MED includes two arms, standard of
care and losartan vs. standard of care and placebo.
Hydroxychloroquine was initially included in COVID MED based on suggestive in vitro, animal
preclinical, and early RCT data, and widespread empiric use in hospitalized patients with
COVID-19. Lopinavir/ritonavir, an antiretroviral medication, showed equivocal and possibly
positive efficacy and safety in an early pandemic Chinese RCT published in NEJM. After public
release and eventual publication of the negative results for hydroxychloroquine and then
lopinavir/ritonavir initially from the RECOVERY trial and then others, enrollment in COVID
MED in these two arms was halted and then discontinued permanently. Data from subjects
enrolled in the hydroxychloroquine arm are being incorporated into a pooled analysis of RCTs
by the Trial Innovation Network.
Losartan, an angiotensin II receptor blocker (ARB), has theoretical benefit as SARSCoV-2
appears to bind to lung tissue via Angiotensin-Converting Enzyme 2 (ACE-2) receptors which
might be inhibited by ARBs; other potential benefits have been hypothesized as well. Since
the initial iteration of this protocol, observational studies have shown that patients
already taking ACEi/ARB medications do not have adverse outcome when these drugs are
continued in hospitalized COVID-19 patients. These data have reinforced continuation of the
losartan vs. placebo arms of this RCT which are ongoing.
This pragmatic adaptive trial continues to compare outcome in hospitalized COVID-19 patients
treated with standard of care and losartan vs. standard of care and placebo.
