Long COVID rehab study halted early – what we know
NCT ID NCT05398692
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at whether a supervised exercise and pulmonary rehabilitation program could help people with Long COVID feel better and move more easily. Researchers measured changes in aerobic capacity, fatigue, and quality of life in 21 adults who had COVID at least 12 weeks earlier. The study was terminated early, so the findings are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- On-site exercise and pulmonary rehabilitation program
- What this could lead to
- If successful, this program could offer a structured way to improve fitness and reduce fatigue for people with Long COVID.
- What could go wrong
- The study was terminated early with only 21 participants, so results are limited and may not apply broadly. Exercise may worsen symptoms like post-exertional malaise in some patients.

Inclusion Criteria: * Long COVID-19 Infection (Documented by PCR or patient report) * Age \>= 18 years old. * At least 12 weeks since the initial COVID Infection. * One or more of the following symptom/signs: Fatigue, Dyspnea, Exercise Intolerance, Post Exertional Malaise and/or Difficulty Breathing. * Able to perform a cardiopulmonary exercise test. Exclusion Criteria: * Patients is not able to perform technically acceptable pulmonary function tests and symptom-limited cardiopulmonary cycle ergometry tests. * Patients who desaturate to SpO2 \<80% on screening incremental exercise testing. * Patients who have completed a pulmonary rehabilitation program in the six weeks prior to the screening visit or patients who are currently in a pulmonary rehabilitation program. * Patients who have taken an investigational drug within one month or six half-lives (whichever is greater) prior to screening visit (Visit 1). * Pregnant or nursing women. * Women of childbearing potential who are not using a highly effective method of birth control. Female patients will be considered of childbearing potential unless surgically sterilized by hysterectomy or bilateral tubal ligation, or post-menopausal for at least two years. * Patients who are currently participating in another interventional study. * Malignancy for which the patient has undergone resection, radiation therapy, or chemotherapy within the last 2 years * Any other significant disease than COVID-19 which, in the opinion of the investigator, may i) put the patient at risk because of participation in the study, ii) influence the results of the study (e.g. Insulin or testosterone therapy, systemic corticosteroids, HIV, etc), iii) cause concern regarding the patient's ability to participate in the study.
