About this study

Official title: Hydroxychloroquine for the Treatment of SARS-CoV2 (COVID 19) in the Critically Ill Patient: Pharmacokinetic Study. (CHLORO-VID)

This study is a prospective, observational, open, monocentric multisite, pharmacokinetic study of hydroxychloroquine in critically ill patients. The aim of this study is to assess the pharmacokinetic behavior of hydroxychloroquine in COVID-19 critically ill patients treated with crushed hydroxychloroquine tablets (administered enterally using a nasogastric tube).

Read the detailed description

Based on the in vitro activity against SARS-CoV-2 and preliminary clinical data, hydroxychloroquine is currently used in the management of COVID-19 patients. In the meantime, the efficacy as well as the dosage of hydroxychloroquine is highly debated. Because of the severity of COVID-19 and the pharmacokinetics of hydroxychloroquine in systemic lupus erythematosus patients, a loading dose was rapidly included in the new hospital regimens to optimize drug distribution in tissues and more precisely in the lungs. Due to the lack of information on the plasma/blood concentrations required to induce a virological/clinical effect, plasma/blood concentration is monitored in many European countries for patients whether or not they are included in clinical research protocols. This problem of relationship between efficacy and exposure is important in the critically ill patient because both the bioavailability and the variability of the pharmacokinetic parameters are potentially responsible for variations in concentrations.

This study is a prospective, observational, open, multisite, pharmacokinetics study of hydroxychloroquine in critically ill patients. There is no supplemental intervention or additional samples compared to the standard care of these patients in our teaching hospital. The total duration of the study is that of the duration of hospitalization in intensive care. The duration of the pharmacokinetic study is 9 days, starting on D1 of the treatment with hydroxychloroquine, and ending with the last recommended residual plasma control. The total duration of treatment with hydroxychloroquine is 10 days, as recommended by the High Council of Public Health in its opinion of March 23, 2020.

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19 Pneumonia, run by University Hospital, Toulouse at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 16 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

residual plasma concentration (time frame: Day 3). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2023.
