Who can take part
You may be able to join if
- Participant between 18 to 80 years (inclusive) of age.

- Diagnosis of pulmonary sarcoidosis (at least 6 months before Screening) using the 2020 American Thoracic Society (ATS) Clinical Practice Guideline (Crouser et al, 2020), the European Respiratory Society (ERS) or the WASOG criteria including a compatible clinical and radiologic presentation with other causes of granulomatous disease ruled out(cutaneous and ocular involvement permitted).
- Modified Medical Research Conference (mMRC) Dyspnea Scale of ≥ l.

You likely can't join if
- PART A ONLY: Known potentially significant fibrotic disease and/or active inflammation contained solely in the hilar region as shown by high-resolution computed tomography (HRCT), confirmed by a central reader. Participants with current active inflammation in the hilar region with concurrent inflammation outside the hilar region may be included. For participants with disease onset of <2 years, a historical computed tomography (CT) within 6 months prior to screening confirmed by a central read is acceptable. For participants with disease onset of >2 years and without a CT within 6 months prior to screening, a CT will be performed at Screening. Note: For all participants, regardless of their time of disease onset, if a historical HRCT is to be submitted for diagnosis confirmation, that HRCT must have been performed within 6 months of screening. If their last HRCT was from > 6 months prior to screening, then they will need to have an HRCT performed during screening for diagnosis confirmation. Note: Significant fibrotic disease is defined as > 20% fibrosis on HRCT
- Clinically significant hepatic or renal disease, including uncontrolled diabetes at the discretion of the investigator.
- Any severe prior reaction to any type of biologics or human blood product such as albumin, IgG, etc.
- PART A ONLY: Any prior TNFα inhibitor therapy.
- Concurrent emphysema.
- Known hypercalcemia due to non-sarcoidosis conditions such as untreated hyperparathyroidism, at the discretion of the investigator

- PART A ONLY: Any prior TNFα inhibitor therapy.
- Concurrent emphysema.
- Known hypercalcemia due to non-sarcoidosis conditions such as untreated hyperparathyroidism, at the discretion of the investigator
- Abnormal ECG: ventricular arrhythmias (non-sustained ventricular tachycardia (VT), multifocal or frequent premature ventricular contractions, bundle branch block, axis deviation, or abnormal Q waves). In the case of a QTcF (corrected QT interval by Fredericia) interval >450 ms (men) or >480 ms (women; participants with bundle branch block) or PR interval outside the range of 120 to 220 ms, the assessment may be repeated once for eligibility determination at Screening or Baseline.
