RECLAIM: Recovering From COVID-19 Lingering Symptoms Adaptive Integrative Medicine

REcovering From COVID-19 Lingering Symptoms Adaptive Integrative Medicine (RECLAIM)

Source: ClinicalTrials.gov · Last updated 23 Feb 2026

Brief summary (registry, in English)

The researchers propose to develop a Canada-wide, adaptive randomized clinical platform trial to assess the effectiveness of various interventions in patients with lingering symptoms of COVID-19 ("Long COVID"). Participants will be randomized initially to 1 of 3 arms, including placebo (control) and 2 interventions. Because this is an adaptive trial, arms can be dropped if found to be ineffective and new arms can be added. Interventions will last for 2 months and participants will be followed for an additional 4 months (6 months total). Approximately 800-1000 patients with Long COVID will be recruited across Canada. Results from this trial will accelerate the availability of high-quality, real-time evidence and solutions to enable Canada to improve the clinical care of patients with Long COVID.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Other illness

  • Patients who had mechanical ventilation or extracorporeal membrane oxygen (ECMO) for COVID-19;
  • Current end-organ failure, organ transplantation, or current hospitalization in acute care hospital;

Other

  • Contraindications to all of the study interventions;
  • Co-enrolment in another interventional trial (co-enrolment in an observational study is permitted);
  • Currently pregnant or breastfeeding.

Who the study is looking for

  • Age ≥18 years;
  • Positive COVID-19 test by nasopharyngeal swab RT-PCR (reverse transcription polymerase chain reaction) test, antibody or antigen tests at least 3 months prior to randomization; OR Presumed COVID-19 assessed by the site investigator (no positive COVID-19 test) with acute illness after October 15, 2019.
  • Patients should be treated with standard of care therapies (as discussed in the study manual) for at least 4 weeks prior to entry into trial.
  • Lingering COVID-19 symptoms beyond 3 months from onset of acute COVID and symptoms have lasted at least 2 months. The onset of COVID is considered the earliest of two dates: the date of positive test or the date of first symptoms;
  • Lingering symptoms from COVID-19 present at the time of randomization.
  • Female patients of childbearing potential (as assessed by the overseeing Investigator) who are sexually active must agree to practice true abstinence or use effective methods of contraception while on study treatment. Effective methods of contraception must be discussed and approved by the overseeing Investigator.
  • Must be able to provide informed consent and both willing and able to comply with study requirements.
