Pfizer
  Purpose
The objective of this study is to evaluate and compare efficacy of 3 dose levels of PF-04236921 to placebo in subjects with generalized lupus using a measure called the Systemic Lupus Erythematosus (SLE) Responder Index. The study will evaluate secondary and exploratory measures as well.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Double-blind, Randomized, Placebo-controlled, Multicenter, Dose-ranging Study To Evaluate The Efficacy And Safety Of Pf-04236921 In Subjects With Systemic Lupus Erythematosus (Sle)

Primary Outcome Measures:
  • The primary endpoint of the study is the proportion of subjects achieving the SLE Responder Index (SRI). [ Time Frame: week 24 ]

Secondary Outcome Measures:
  • Percentage of subjects with an improvement of greater than or equal to 4 in the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K score. [ Time Frame: week 24 ]
  • Percentage of subjects with no new British Isles Lupus Assessment Group (BILAG) A organ domain scores or 2 new BILAG B organ domain scores [ Time Frame: week 24 ]
  • Percentage of subjects with No worsening of Physician's Global Assessment (PhGA) score. [ Time Frame: week 24 ]
  • Percentage of subjects who develop anti-drug antibodies (ADAs) and neutralizing antibodies (Nabs), if observed. [ Time Frame: week 24 ]
  • Mean change from baseline in patient reported outcome measures using Short Form-36, European Quality of Life-5 Dimensional questionnaire, Functional Assessment of Chronic Illness Therapy-Fatigue and Visual Analog Scale scores. [ Time Frame: week 24 ]
  • Proportion of subjects achieving SRI at all timepoints except Week 24 [ Time Frame: week 4, 8, 12, 16, and 20 ]
  • Proportion of subjects achieving modified SRI at all timepoints [ Time Frame: week 4, 8, 12, 16, 20, and 24 ]
  • Proportion of subjects achieving BILAG based Combined Lupus Assessment (BICLA) response at all timepoints [ Time Frame: week 4, 8, 12, 16, 20, and 24 ]
  • Percentage of subjects with abnormal immunoglobulins, anti-dsDNA, C3, or C4 at baseline that become normal. [ Time Frame: week 24 ]
  • Percentage of subjects receiving corticosteroids greater than 7.5 mg per day whose dose has been reduced by both >= 25% from baseline and to <= 7.5 mg per day during Week 12 through Week 24. [ Time Frame: week 24 ]
  • Evaluate the safety and tolerability of PF-04236921 at the different dose levels compared to placebo for adverse events, laboratory changes, ECGs, and vital signs. [ Time Frame: Week 4, 8, 12, 16, 20, and 24 ]
  • Blood concentration of PF-04236921 [ Time Frame: Week 4, 8, 12, 16, 20, and 24 ]
