Have HRCT scan at screening consistent with pulmonary sarcoidosis of the lung parenchyma by central read. Note: An HRCT performed as part of clinical care may be used as the screening HRCT as long as the HRCT is performed within 4 weeks of the Screening Visit and is uploaded and deemed of acceptable quality by the imaging vendor/central reader. If not of acceptable quality for study inclusion, it needs to be obtained again as part of the study inclusion procedures. 5. ppFVC ≥ 50% and DLCO (hemoglobin corrected value) ≥ 40% predicted at screening. 6. If receiving prednisone (or equivalent), dose must be ≤ 25 mg, and dose must have been stable for at least 4 weeks prior to screening. In addition, subject must agree to taper their steroids beginning at the time of randomization. 7. If receiving methotrexate and/or other IST, subject must agree to cessation of their IST therapy at randomization. 8. Have additional evidence of active pulmonary sarcoidosis as defined by: a. Medical Research Council Dyspnea scale > 1 (i.e., Grade 2 or more) at screening; AND b. Currently on a treatment regimen for pulmonary sarcoidosis that includes OCS, IST, or the combination of OCS and IST. If not currently being treated with either OCS or IST, subjects can still be eligible if there is documentation in the medical records that they have taken OCS and/or IST in the past 2 years for their pulmonary sarcoidosis and have been unable to tolerate them, treatment was not effective, or they subsequently refused to continue taking these medications; AND c. One or more of the following is present: i. Screening FDG-PET scan showing pulmonary parenchymal uptake consistent with active pulmonary sarcoidosis AND with pulmonary parenchymal SUVmax ≥ 3 on central read; Note: A PET/CT performed as part of clinical care may be used as the screening PET/CT as long as the PET/CT is performed within 4 weeks of the Screening Visit and is uploaded and deemed of acceptable quality by the imaging vendor/central reader. If not of acceptable quality for study inclusion, it needs to be obtained again as part of the study inclusion procedures. ii. Documentation in the subject's medical record of worsening sarcoidosis (i.e., a clinically meaningful worsening in pulmonary function parameters (e.g., ≥ 5 percent decline in ppFVC) or clinically relevant worsening of radiographic findings (e.g., HRCT, chest x-ray) in the past 12 months); iii. Documentation in the subject's medical record that tapering OCS (≥ 5 mg change) and/or tapering ISTs during the past 12 months resulted in an increase of pulmonary disease symptoms, signs, or activity necessitating maintenance or increase in dose of OCS and/or IST. 9. Female subjects must agree to use an approved highly effective birth control (BC) method (< 1% failure rate per year) for at least 4 weeks prior to randomization, throughout the study, and for 18 weeks following the last dose of study drug, unless documented to have a reproductive status of non-childbearing potential or is postmenopausal as defined below: a. Non-childbearing potential defined as pre-menopausal female with medical history of total hysterectomy, bilateral oophorectomy (removal of ovaries), bilateral salpingectomy, bilateral tubal ligation, or bilateral hysteroscopic sterilization at least 3 months prior to screening; b. Postmenopausal defined as 12 months of spontaneous amenorrhea without an alternative medical cause. 10. Male subjects must agree to use condoms when having sexual intercourse with female partners of childbearing potential and attest that female partners of childbearing potential will use a highly effective method of contraception as described above for at least 4 weeks prior to randomization/enrollment, throughout the study and for 18 weeks following the last dose of study drug. Male subjects must also agree to not donate sperm from the time of signing consent until 18 weeks following the last dose of study drug. 11. Body Mass Index (BMI) ≤ 40 kg/m2 at screening 12. Vaccination for COVID-19 with completion of the primary series at least 2 weeks prior to randomization.
