Is this trial a fit for you?

Likely a good fit

Ideal candidates are de novo adult liver transplant recipients who are two to three months post-transplant and have access to a home freezer.

Probably not a fit

Patients with severe comorbidities, ongoing malignancies, or those unable to participate in physical exercise due to medical contraindications may not benefit from this study.

What this trial studies

This study investigates the impact of different exercise intensities on the rehabilitation of patients who have recently undergone liver transplantation. Participants will be randomly assigned to one of three training groups (low, moderate, or moderate to high intensity) and will engage in a six-month home-based rehabilitation program supervised by a PHOENIX investigator. Assessments of physical fitness, cardiovascular health, liver function, and body composition will occur at baseline, three months, and six months, alongside monthly questionnaires to evaluate well-being and quality of life. The study aims to establish a feasible and effective exercise regimen to improve long-term outcomes for liver transplant recipients.

Why it matters

Potential benefit: If successful, this program could significantly enhance physical fitness and reduce cardiovascular risks in liver transplant recipients.

How similar studies have gone: Previous studies have shown positive outcomes with structured rehabilitation programs for transplant recipients, suggesting this approach may be effective.
