Phase Ib Study of SC Milatuzumab in SLE

Phase 1

Completed

• Conditions: Lupus Nephritis; Lupus Erythematosus, Cutaneous; Lupus Erythematosus, Systemic; Lupus Erythematosus, Discoid; Lupus Vasculitis, Central Nervous System
• Interventions: Drug: milatuzumab; Drug: Placebo

• Registration Number: NCT01845740
• Lead Sponsor: Gilead Sciences

Brief Summary

Milatuzumab will be given subcutaneously at different dose levels once (depending on the dose level) for 4 weeks to determine if milatuzumab helps to control lupus (SLE).

Detailed Description

Milatuzumab or placebo will be given subcutaneously once weekly for 4 weeks to determine if milatuzumab helps to control lupus (SLE). The treatment portion of the study lasts 4 weeks. Then patients are followed for disease activity for at least 12 weeks. If patients respond to the study drug, they may be eligible for one course of retreatment, again followed by 12 weeks of follow-up. Patients who showed a response will continue to be followed at timepoints up to one year after treatment to assess how long the response lasts.

Arm && Interventions

Group	Intervention	Description
Milatuzumab SC 250 mg	milatuzumab	Milatuzumab 250 mg will be administered subcutaneously once weekly for 4 weeks.
Milatuzumab 150 mg SC	milatuzumab	Milatuzumab 150 mg will be administered subcutaneously once weekly for 4 weeks.

Primary Outcome Measures

Name	Time	Method
Safety and Tolerability	up to 2 years	Will be assessed using laboratory and clinical data comparing baseline lab results and clinical condition to the lab results and clinical condition/adverse events during treatment and follow-up timepoints up to 2 years.
Obtain preliminary evidence of efficacy for patients with active disease.	up to 2 years	Will be assessed using the BILAG scoring model for lupus disease activity and symptoms by comparing baseline BILAG measurements against the BILAG measurements obtained during treatment and during follow-up for up to 2 years.
