Study Details

Study Description

Brief Summary

This study will be a multicenter, randomized, double-blind, placebo-controlled, multiple dose study in which approximately 24 subjects with SCLE will be enrolled. Cohort 1 will consist of 12 subjects (6 AMG 557: 6 placebo) randomized to receive AMG 557 210 mg or matching placebo. Cohort 2 will consist of 12 subjects (6 AMG 557: 6 placebo) randomized to receive AMG 557 140 mg or matching placebo. Enrollment of Cohort 2 (140 mg) will be initiated after enrollment of Cohort 1 (210 mg) is completed.

Detailed Description

Cohort 1 will consist of 12 subjects (6 AMG 557: 6 placebo) randomized to receive AMG 557 210 mg or matching placebo. Cohort 2 will consist of 12 subjects (6 AMG 557: 6 placebo) randomized to receive AMG 557 140 mg or matching placebo. Enrollment of Cohort 2 (140 mg) will be initiated after enrollment of Cohort 1 (210 mg) is completed. After Cohort 1 and 2 enrollment has been completed, the emerging PK and PD data will be reviewed to determine if an additional 4-8 subjects with SCLE will be enrolled into the study to address equivocal results from the study. These 4-8 additional subjects will receive the same dose of either 210 mg or 140 mg SC (in an allocation ratio of 1 AMG 557: 1 placebo).

In addition, an open label extension study for participants in this study may be instituted following completion and analysis of results of this study. Initiation of this study will require that an acceptable risk-benefit profile and some evidence of efficacy are observed in the current study.

Outcome Measures

Primary Outcome Measures

Safety evaluation: Subject incidence of treatment-emergent adverse events, vital signs, physical examinations, clinical laboratory safety tests, ECGs, and the incidence of binding and neutralizing antibodies to AMG 557 [253 Days]

Secondary Outcome Measures

Determine the pharmacokinetic (PK) profile of AMG 557 after multiple subcutaneous (SC) doses in subacute cutaneous lupus erythematosus (SCLE) subjects. [253 Days]
Characterize the mean change and variability in serum SS-A and SS-B autoantibodies. [253 Days]

In addition, prescription drugs for hypertension or hypercholesterolemia, oral hypoglycemic drugs, or NSAIDs will be allowed; however, NSAIDS are not permitted within 24 hours of skin biopsies to reduce the risk of bleeding. Other medications may be approved following review by the Principal Investigator and the Amgen Medical Monitor. Written documentation of this review and Amgen acknowledgement is required for subject participation;
