This study tests the safety and effectiveness of ustekinumab or golimumab compared to placebo (placebo looks like the drugs being studied, but has no active ingredients). The purpose of this research study is to determine if ustekinumab or golimumab is safe and to determine its effects (good and bad) on patients with chronic sarcoidosis with pulmonary and/or skin involvement. Patients with pulmonary involvement constitute the primary population for analysis, and patients with skin involvement constitute the secondary population; a patient may be in both populations. The study will be conducted at approximately 40 sites globally.
