New combo therapy aims to slow lung scarring in hypersensitivity pneumonitis
NCT ID NCT05626387
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 4 trial tests whether adding mycophenolate mofetil (MMF) to standard prednisolone treatment works better than prednisolone alone for fibrotic hypersensitivity pneumonitis, a lung condition where scarring makes breathing hard. About 144 adults with at least 40% predicted lung function will be randomly assigned to one of the two groups. The main goal is to see how fast lung function declines over one year.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mycophenolate mofetil (MMF) plus prednisolone
- What this could lead to
- If it works, this could provide a more effective and safer treatment option for people with fibrotic hypersensitivity pneumonitis, potentially slowing lung function decline.
- What could go wrong
- This is a relatively small, single-center trial. The combination therapy may not prove more effective than prednisolone alone, and immunosuppressants carry risks like infection and bone marrow suppression.

Inclusion Criteria: i. A diagnosis of fibrotic hypersensitivity pneumonitis according to the criteria proposed in the American Thoracic Society Guideline 2020 ii. Screening FVC at least 40% of the predicted value iii. Able to provide a written, informed consent for participation in the trial Exclusion Criteria: i. Baseline FVC \<40% predicted ii. Leucopenia (white blood cell count \<4·0 × 10\^9 per L), significant thrombocytopenia (platelet count \<100 × 10\^9 per L), or clinically significant anemia (hemoglobin \<10 g/dL) iii. Baseline liver transaminases (alanine aminotransferase and aspartate aminotransferase) or bilirubin more than 1·5 times the upper normal limit (except in the case of Gilbert's syndrome) iv. Serum creatinine higher than 2.0 mg/dL v. Uncontrolled congestive heart failure vi. Receipt of prednisolone (more than or equal to 10 mg/day, or equivalent), in the 4 weeks before randomization vii. Prior use of prednisolone (more than or equal to 10 mg/day, or equivalent), MMF, azathioprine, cyclophosphamide, cyclosporine or any other non-glucocorticoid immunosuppressant drug, or antifibrotic agents for more than 12 weeks in the previous year viii. Active infection (lung or elsewhere) whose management would be compromised by MMF or prednisolone ix. Other serious concomitant medical illness (eg, cancer), chronic debilitating illness (other than chronic HP), or drug abuse x. Pregnancy (documented by urine pregnancy test) or breastfeeding xi.
