Brief summary

The purpose of this study is to learn about the effects, safety and how PF-06823859 is processed in adults with cutaneous lupus erythematosus (CLE) or systemic lupus erythematosus (SLE) showing some skin symptoms. This study is seeking for participants who: * are adults of 18 years of age or older. * are confirmed to have CLE or SLE with involvement of the skin. * have a Cutaneous Lupus Erythematosus Disease Area and Severity Index activity (CLASI-A) score of at least 8. About 48 participants will be selected to receive active study medicine (PF-06823859) or placebo (an infusion without drug). About 32 are grouped to receive the active study medicine and 16 are to receive placebo. They will be receiving the treatments by intravenous infusion (injected directly into the veins). At week 16 all participants receiving the active study drug since day 1 and participants who have received placebo since day 1 and are not responding clinically will receive active study medication. Patients who have received placebo since Day 1 and who have had a clinical response will continue to receive placebo till week 40. All participants will have last follow-up visit at Week 60. The study will compare participants receiving PF-06823859 to participants who receive placebo. This will help us see if PF-06823859 is safe and effective to treat CLE or SLE with skin symptoms and improve participant's CLASI-A score. Participants will take part in this study for about 65 weeks. This includes up to a 5-week selection period, a 12-week Q4Wk treatment period, a 36-week Q8Wk treatment period, and a 12-week follow-up period.

Intervention model description

About 48 eligible participants will be randomized in a 2:1 ratio to receive either PF-06823859 or placebo. Following assessments for the primary endpoint at Week 12, participants who are receiving active PF-06823859 or who are placebo non responders (responder is defined by ≥4 point reduction from the baseline in CLASI-A score) will receive PF-06823859 beginning at Week 16, while placebo responders will continue to be in the placebo group. The last dose of study intervention will be administered at Week 40 followed by last full study assessments at Week 48. The final follow up visit will be conducted at Week 60.

Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline in Type 1 Interferon (IFN) Gene Signature (GS) Score in Lesional Skin at Week 12Baseline, Week 12Change from baseline GS was calculated as GS(t) - GS(0), where GS(t) was the gene signature score at Week 12 and GS(0) was the gene signature score at Baseline, where the GS(t) was calculated as the mean of log2 transformed counts per million reads from each of 13 genes in RNAseq, the higher GS indicated coordinated higher expression. There is no minimum/maximum limit to the GS score. Gene expression was quantified using RNA sequencing and summarized as log2-transformed counts per million mapped reads \[log2(CPM)\]. Higher values indicate higher normalized gene expression and without a bounded scale or defined minimum or maximum value.

Recruitment details

Initially participants were randomized to receive PF-06823859 or placebo in Period 1. In Period 2, participants in PF-06823859 group continued to receive the same, while participants who received placebo, depending upon the response, either continued receiving placebo (if responded to treatment) or were administered with PF-06823859 (non-responders). No participants continued to receive placebo in Period 2.

Pre-assignment details

As per Sponsor's decision, dose strength of PF-06823859 is not disclosed and is designated as "Dose A" in every section of the record. The study was terminated due to sponsor decision and was not due to safety concerns or clinical effect reasons or request from any regulatory authorities.
