Study of Safety and Tolerability of CFZ533 in Patients With Sjögren's Syndrome

• Status: Recruiting
• Trial end date: 2024-02-15
• Target enrollment: 0

Additionally, this Extension study will further explore the pharmacokinetics (PK) and efficacy of iscalimab at two dose level.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

Participants eligible for inclusion in this study must meet all of the following criteria:

1. Participants must have participated in the TWINSS core study, CCFZ533B2201 (NCT03905525), and must have completed the entire treatment period up to Week 48 and the follow-up period up to Week 60

2. Signed informed consent must be obtained prior to participation in the Extension study (i.e. before commencement of the Week 60 assessments of the core study)

3. In the judgement of the Investigator, participants must be expected to clinically benefit from continued iscalimab therapy

Exclusion Criteria:

Participants meeting any of the following criteria are not eligible for inclusion in this study.

1. Sjögren's Syndrome overlap syndromes where another autoimmune rheumatic disease constitutes the principle illness, specifically:

• Moderate-to-severe active systemic lupus erythematosus (SLE) with anti-dsDNA positivity and renal involvement, or other organ involvement that impedes on ability to score ESSDAI domains

• Active rheumatoid arthritis (RA) that impedes on the ability to score the ESSDAI articular domain

• Systemic sclerosis

• Any other concurrent connective tissue disease (e.g., lupus nephritis (LN), large vessel vasculitis (LVV), Sharp syndrome (mixed connective tissue disease) that is active and requires immunosuppressive treatment outside the scope of this trial and would impede on Sjögren's Syndrome organ domain assessments

2. Use of other investigational drugs other than iscalimab during the core study

3. Active uncontrolled viral, bacterial or other infections requiring systemic treatment at the time of enrollment, or history of recurrent clinically significant infection or of bacterial infections with encapsulated organisms

4. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human Chorionic Gonadotropin (hCG) laboratory test

5. Women of child-bearing potential (WOCBP), defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 14 weeks after stopping of investigational drug.

6. Missing ESSDAI (Cohort 1 and Cohort 2) or ESSPRI (Cohort 2) scores in the core study at Weeks 0 and 4 or Weeks 40 and 48.
