RCT of Nintedanib in Fibrotic Sarcoidosis

Phase 4

Recruiting

• Conditions: Sarcoidosis, Pulmonary
• Interventions: Drug: Standard of care; Drug: Nintedanib

• Registration Number: NCT06479603
• Lead Sponsor: Post Graduate Institute of Medical Education and Research, Chandigarh

Brief Summary

Sarcoidosis is generally managed with outdoor immune modulatory drugs, most commonly oral steroids and at times drugs like methotrexate or azathioprine as a steroid sparing agent.

Around 15-20% of sarcoidosis patient develop fibrosis of the lung parenchyma. The effect of antifibrotics in such patients needs more studies. Nintedanib has been used with good results in patients with fibrosing interstitial lung disease like IPF, SSC- ILD, and other progressive fibrosing ILD. By using nintedanib in fibrotic sarcoidosis we may be able to limit the functional disability in these patients by slowing the rate of fibrosis and loss of lung function. The use of nintedanib if results in decrease in fibrosis and consequent decline in loss of lung function then it may be a safe and viable option for such patients.

We hypothesise that in patients with fibrotic sarcoidosis on standard of care anti-inflammatory therapy, nintedanib may help in reducing the rate of decline in lung function and progressive fibrosis. We aim to evaluate the efficacy and safety of nintedanib in subjects with fibrotic sarcoidosis

Detailed Description

Setting: This prospective randomised controlled trial will be conducted in the Chest Clinic of the Department of Pulmonary Medicine, PGIMER, Chandigarh after approval from the ethics committee.

Study design: Open label parallel group randomized controlled trial Blinding: This will be an open label trial. Neither the subject nor the investigators will be blinded to the assigned group. The individual administering the Kings Sarcoid Questionnaire (KSQ) will be blinded to the group allocation.

Study participants: Diagnosed cases of pulmonary sarcoidosis of fibrotic phenotype who are on stable immunosuppressive therapy would be enrolled after screening for inclusion and exclusion criteria. Consecutive subjects with fibrotic sarcoidosis will be screened for this study. They will undergo the following investigations: complete blood counts, liver and kidney function tests, and an electrocardiogram (ECG) in addition to a thin-section chest CT (if a recent scan within 6 months of screening is unavailable) or a positron emission tomography (PET) if indicated clinically, spirometry, and a six-minute walk test (6MWT). A venous blood sample (total of 10 mL) will be collected in plain and EDTA vials and stored for cytokine analysis and other testing.

Arm && Interventions

Group	Intervention	Description
Standard of care	Standard of care	The subjects will receive the standard-of-care immunosuppressive treatment alone.
NIntedanib	Nintedanib	The subjects will receive oral nintedanib. It will be prescribed to be taken after meals with 12 hrs gap between doses. The drug will be started at a dose of 100 mg twice daily. After 2 weeks, the dose will be titrated up to 150 mg twice daily, which will be continued till the end of 52 weeks. The standard-of-care immunosuppressive treatment will be continued along with the study drug (nintedanib). In case of intolerance to the 300 mg/day dose of nintedanib, the dose will be reduced to 100 mg twice daily.
