About this study

Official title: Feasibility Pilot Clinical Trial of Omega-3 (EPA+DHA) Supplement vs. Placebo for Post-Acute Sequelae of Coronavirus-19 (COVID-19) Recovery Among Health Care Workers

This is a two-arm, double blind randomized 12-week study to supplement omega-3 (Eicosapentaenoic acid - EPA + docosahexaenoic acid - DHA) among 100 adults (age 18+) who had coronavirus-19 (covid-19) and are experiencing possible after-effects from post-acute sequelae of covid-19 (also called post-covid syndrome or long covid syndrome).

Read the detailed description

This is a double-blind, randomized controlled trial (RCT) with two treatment arms:

Arm 1 - Omega-3 (Eicosapentaenoic acid - EPA + docosahexaenoic acid - DHA) - Dose is 2,100mg per day via 3 mini-capsules, 2x/day (a total of 6 mini-capsules per day). Each capsule has 252mg of EPA and 102mg of DHA.

Support for dosing:

  • The American Heart Association (AHA) says taking up to 3 grams of fish oil daily in supplement form is considered safe;
  • Up to 5,000mg of omega-3 fatty acids per day is considered safe;
  • The U.S. Food and Drug Administration recommends consuming no more than 3 g/day of EPA and DHA combined, including up to 2 g/day from dietary supplements.

Arm 2 - Placebo - made from soybean oil (same dosing schedule as intervention arm)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Omega-3 (EPA+DHA) in people with COVID-19, run by Hackensack Meridian Health at 1 site in United States.

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 16 inclusion and 16 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: stopped early, as of the sponsor's last update on 19 Sep 2024. 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 United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Sep 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Feasibility Study for Omega-3 Fatty Acid Supplementation v. Placebo in Adult Patients to Limit Long Covid Syndrome - Compliance as Captured by the Number of Participants Who Remain Compliant for the Whole Duration of the Study by Taking All Pills Daily (time frame: 12 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05121766, which also lists 4 linked publications.

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 19 Sep 2024.
