Study summary

Since the onset of the disease, more than 40.5 million people have been diagnosed with COVID-19 and nearly 1.2 million people have died (October 21, 2020). There is no complete understanding of the pathogenesis of SARS-CoV-2 infection and to this day there is no specific therapy or vaccine available. Thus, patient care is based on symptomatic therapy and treatment of complications.

Ivermectin has been used for more than 30 years for the treatment of several diseases. More than one million doses of the drug are administered daily, particularly in low- and middle-income countries. Due to the low prevalence of adverse events with the use of this drug, ivermectin is considered to have a good safety profile and its potential benefit in other diseases is currently under investigation.

An in vitro study of ivermectin in SARS-CoV-2 in Australia showed a significant reduction of viral load in infected cells. Subsequently, a descriptive study of 704 critical patients with COVID-19 showed a reduction in mortality, hospitalization, and intensive care unit length-of-stay in those patients who received the drug. Unfortunately, this study was withdrawn by its authors, leaving more questions than answers.

Some countries in Latin America have authorized its use for the management of patients with COVID-19 even in the absence of solid evidence, and several other countries are conducting clinical trials to evaluate its efficacy for the treatment of moderate and severe disease.

Since there is no specific treatment for COVID-19 and the therapeutic options are scarce, the researchers believe it is completely plausible, urgent, and necessary to evaluate if ivermectin use reduces the risk of admission to an intensive care unit (ICU) in hospitalized adults with severe COVID-19. The proposal is a randomized, double-blind clinical trial, conducted at CES Clinic, Medellin-Colombia. The investigators will randomize 100 patients with severe, non-critical illness, into two groups, one group will receive ivermectin in addition to standard management and the other group will receive placebo plus standard management. Clinical outcomes to evaluate will be ICU admission, need for mechanical ventilation, length of hospital stay, days in the ICU and mechanical ventilation, and finally, the incidence of adverse events related to the intervention. The estimated time to complete the study is approximately five months.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 4, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
