Who can take part

• Subjects ≥ 21 years at the time of signing the informed consent

• If on pirfenidone or nintedanib, participants must have been on a stable dose for at least 90 days prior to screening
• If not currently on pirfenidone or nintedanib, participants must not have received either of these medications within 28 days prior to screening
• Mycophenolate mofetil (MMF), mycophenolic acid (MA), azathioprine (AZA), and Tacrolimus are permitted provided that the participant is on a stable dose for at least 90 days prior to screening. If not currently on MMF, MA, AZA, or tacrolimus, participants must not have taken these medications within 28 days prior to screening
• Traditional disease-modifying antirheumatic drug (DMARDs) (eg. Methotrexate, leflunomide, sulfasalazine, or hydroxychloroquine) are permitted provided that the participant is on a stable dose for at least 90 days prior to screening. If not currently on traditional DMARD, participants must not have taken these medications within 28 days prior to screening
• Biologic DMARDs (eg. TNF blockers and IL-1 inhibitors) and Janus kinase inhibitors (JAK) (inhibitors eg. tofacitinib, upadacitinib) are permitted provided that the participant is on a stable dose for at least 90 days prior to screening. If not currently on Biologic DMARD or JAK inhibitor, participants must not have taken these medications within 28 days prior to screening

• Exhibit symptoms of heart failure at rest
• Participants who have: 1) a current malignancy, 2) a previous malignancy with less than 2 years free of recurrence, 3) a biopsy that is suspicious for malignancy and the possibility of malignancy cannot be ruled out
• Idiopathic pulmonary fibrosis with usual interstitial pneumonia (UIP) verification at screening
