Sjögren Syndrome | Drug: CFZ533 Other: Placebo | Phase 2 |
This is a double-blind, randomized, placebo-controlled, multicenter study of CFZ533 in 2 distinct populations (cohorts) of patients with Sjögren's Syndrome: 1) moderate-to-severe disease (systemic and symptomatic involvement) and; 2) low systemic involvement but high symptom burden.
The study includes up to 6 weeks screening period, 48 weeks of treatment (divided into treatment periods of 24 weeks each) and 12 weeks follow up. Study treatment will be administered as bi-weekly subcutaneous injections.
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 273 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Patients will be screened and enrolled into one of the 2 study Cohorts: Cohort 1: At baseline subjects will be randomized in ratio 1:1:1:1 into one of three CFZ533 (iscalimab) arms (A, B or C) or to placebo (Arm D). After completion of 24 weeks of treatment (Period 1) placebo patients (Arm D) will be switched to active treatment (Arm D1) for the subsequent 24 weeks (Period 2). Cohort 2: At baseline subjects will be randomized in ratio 1:1 to iscalimab (Arm E) or to placebo (Arm F). After completion of 24 weeks of treatment (Period 1), placebo patients (Arm F) will be switched to iscalimab active treatment (Arm F1) for the subsequent 24 weeks (Period 2). All patients treated with iscalimab (Arms A,B,C,and E) in Period 1 will continue the same study treatment in Period 2. |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Masking Description: | Patients, investigator staff, persons performing the assessments, will remain blind to the identity of the treatment within each cohort from the time of randomization until end of the study visit (week 60) |
Primary Purpose: | Treatment |
Official Title: | A 48-week, 6-arm, Randomized, Double-blind, Placebo-controlled Multicenter Trial to Assess the Safety and Efficacy of Multiple CFZ533 Doses Administered Subcutaneously in Two Distinct Populations of Patients With Sjögren's Syndrome (TWINSS) |
Actual Study Start Date : | October 1, 2019 |
Actual Primary Completion Date : | September 28, 2022 |

Chemokine (C-X-C motif) ligand 13 (CXCL13), also known as B lymphocyte chemoattractant (BLC) or B cell-attracting chemokine 1 (BCA-1), is a protein ligand that in humans is encoded by the CXCL13 gene.
