简要总结
This randomized, double-blind, placebo matched to efzofitimod-controlled, study will evaluate the safety, tolerability, immunogenicity, pharmacokinetic (PK), and preliminary efficacy of multiple ascending doses of IV efzofitimod in participants with pulmonary sarcoidosis undergoing a protocol-guided oral corticosteroid (OCS) tapering regimen.This study will consist of 3 staggered multiple dose cohorts. Each eligible participant will participate in only one cohort during the study. Within each cohort, 12 participants will be randomized 2:1 to efzofitimod (N=8) or placebo matched to efzofitimod (N=4).

- •Clinically significant pulmonary hypertension requiring vasodilator treatment.
- •Any history of tuberculosis or evidence of active systemic non-tuberculosis fungal or mycobacterial infection within 1 year of Screening.
- •History of clinically significant cardiac, neurological, gastrointestinal, and/or renal manifestations of sarcoidosis.
- •Any condition that necessitated hospitalization within the 3 months prior to Day 1 or is likely to require so during the study.
- •Participation in another clinical study of an investigational agent or device within 3 months (small molecules) / 6 months (biologics) or 5 half-lives (if known) of the agent, whichever is longer.

- •Positive for Jo-1 antibodies (Ab) at Screening, or past history of Jo-1 Ab positivity.
- •Significant and/or acute illness within 5 days prior to drug administration that may impact safety assessments, in the opinion of the Investigator.
结局指标
主要结局
Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
时间窗: Baseline up to Week 24
An AE was any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. TEAEs were defined as any adverse event or worsening of an existing condition after initiation of the investigational product and through 30 days after the participant's last study visit (study completion or early termination). SAEs included death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized the participant and required medical intervention to prevent 1 of the outcomes listed in this definition. A summary of serious and non-serious AEs regardless of causality is located in 'Reported Adverse Events module'.
