Testing Mycophenolate Mofetil for Fibrotic Hypersensitivity Pneumonitis

Mycophenolate Mofetil and Prednisolone Versus Prednisolone Alone in Fibrotic Hypersensitivity Pneumonitis: a Randomized Controlled Trial

Phase 4 Interventional Pgimer · NCT05626387

This study is testing whether adding mycophenolate mofetil to the usual treatment with prednisolone can help people with fibrotic hypersensitivity pneumonitis breathe better and feel improved.

What this trial studies

This clinical trial aims to evaluate the efficacy and safety of mycophenolate mofetil (MMF) combined with prednisolone compared to prednisolone alone in treating fibrotic hypersensitivity pneumonitis (HP). The study will involve patients diagnosed with fibrotic HP, assessing their lung function and response to treatment over a specified period. By utilizing a randomized controlled design, the trial seeks to provide robust evidence regarding the potential benefits of MMF in this patient population. The hypothesis is that the combination therapy will yield better outcomes than glucocorticoids alone.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals diagnosed with fibrotic hypersensitivity pneumonitis who have a forced vital capacity (FVC) of at least 40% of the predicted value.

Not a fit: Patients with severe lung impairment (FVC less than 40% predicted) or significant blood disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a more effective and safer option for patients suffering from fibrotic hypersensitivity pneumonitis.

How similar studies have performed: While there is limited research specifically on MMF for fibrotic HP, the approach of using immunosuppressive therapies in similar interstitial lung diseases has shown promise in other studies.
