  • No features supporting an alternative diagnosis on transbronchial biopsy, or SLB, if performed prior to Screening.
  • Able to understand and sign a written informed consent form.
  • For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use two adequate methods of contraception, including at least one method with a failure rate of <1% per year, during the 52 week treatment period and for at least 118 days after the last dose of study drug.

    • Medical history including Human Immunodeficiency Virus (HIV);
    • Medical history of viral hepatitis (positive Hep A antibody in the absence of elevated liver enzymes is not an exclusion).
  • Concurrent presence of other pleuropulmonary manifestations of RA, including but not limited to rheumatoid nodular disease of the lung, pleuritis/pleural thickening, and obliterative bronchiolitis.

  • Clinical diagnosis of a second connective tissue disease or overlap syndrome (including but not limited to scleroderma, Sjogren’s, polymyositis/dermatomyositis, systemic lupus erythematosus but excluding Raynaud’s phenomena).
  • Coexistent clinically significant COPD/emphysema or asthma in the opinion of the site principal investigator.
  • Clinical evidence of active infection, including but not limited to bronchitis, pneumonia, sinusitis, urinary tract infection, or cellulitis. The infection should be resolved per PI assessment prior to enrollment. Any use of antibiotics must be completed 2 weeks prior to the screening visit. Note that prophylactic antibiotics are not contraindicated or exclusionary.
