An RCT of Mycophenolate Mofetil (MMF) in Fibrotic Hypersensitivity Pneumonitis

NCT05626387 | Active Not Recruiting Phase 4

Brief Summary

To our knowledge, there is no randomized controlled trial assessing the efficacy of mycophenolate mofetil (MMF) in the treatment of HP. We aim to perform a randomized study to assess the efficacy and safety of a regimen consisting of MMF and prednisolone against a regimen consisting of prednisolone alone for treating fibrotic HP. We hypothesize that the treatment of patients with fibrotic HP with MMF and prednisolone will be more effective and safer than treatment with prednisolone alone.

Conditions

Hypersensitivity Pneumonitis

Keywords

HP; interstitial lung disease; ILD; diffuse parenchymal lung disease

Outcome Measures

Primary Outcomes (1)

• Lung function (FVC) decline

  Annual rate of decline in forced vital capacity (FVC) assessed using spirometry assessed over 52 weeks

  52 weeks

Secondary Outcomes (8)

• FEV1 decline

  52 weeks

• Severity of breathlessness

  52 weeks

• Six-minute walk distance

  52 weeks

• Disease specific health status

  52 weeks

• Diffusion capacity

  52 weeks

Study Arms (2)

Prednisolone alone

ACTIVE COMPARATOR

Oral prednisolone will be administered over 52 weeks, according to following schedule 0.75 mg/kg x 2 weeks 0.5 mg/kg x 2 weeks 20 mg/day x 4 weeks 15 mg/day x 4 weeks 10 mg/day x 4 weeks 5 mg/day x 10 weeks 5 mg on alternate days x 26 weeks

Drug: Prednisolone

Mycophenolate mofetil plus prednisolone

EXPERIMENTAL

Oral prednisolone will be administered according to the schedule in the prednisolone alone arm. Mycophenolate mofetil will be administered starting from 2 weeks after randomization. It will be initiated at a dose of 500 mg twice daily and will be escalated to 1000 mg twice daily after two weeks.

Drug: Mycophenolate Mofetil plus prednisolone

Interventions

Prednisolone DRUG

Prednisolone is a glucocorticoid that suppresses inflammation by several mechanisms.

Also known as: Control

Prednisolone alone

Mycophenolate Mofetil plus prednisolone DRUG

Prednisolone is a glucocorticoid that suppresses inflammation by several mechanisms. Mycophenolate mofetil (MMF) is an immunosuppressive drug that acts by inhibiting the proliferation of T-lymphocytes and suppressing the recruitment of lymphocytes and monocytes into the sites of inflammation.

Also known as: Intervention

Mycophenolate mofetil plus prednisolone
