Study Description
The purpose of this study is to evaluate efficacy, safety and tolerability of s.c.
ianalumab administered in participants with diffuse cutaneous systemic sclerosis relative
to placebo The study consists of the following periods:
- Screening Period, with a duration of up to 6 weeks;
- Treatment Period 1, with a duration of 52 weeks;
- Treatment Period 2 (Open-label treatment), with a duration of 52 weeks;
- Post-treatment Follow-up Period, with a duration of at least 20 weeks post last dose
and up to 2 years.

Eligibility Criteria
Key Inclusion Criteria:
- Male and female participants >= 18 and =< 70 years (at the time of the screening
visit).
- Diagnosis of systemic sclerosis, as defined by the 2013 American College of
Rheumatology/ European League Against Rheumatism (ACR/EULAR) classification criteria
for SSc (van den Hoogen et al 2013) and meet the dcSSc subset classification
according to LeRoy (LeRoy 1988)
- Disease duration of =< 60 months (defined as time from the first non-Raynaud
phenomenon manifestation, e.g., puffy hands, scleroderma, digital ulcers,
arthralgia, dyspnea)
- mRSS units of >= 15 and =< 45 at the time of the screening visit
- Active disease that meets at least one of the following criteria at screening:
- Disease duration of =< 18 months defined as time from the first non-Raynaud
phenomenon manifestation
- Increase in mRSS of >= 3 units compared with the most recent assessment
performed within the previous 6 months
- Involvement of one new body area and an increase in mRSS of >= 2 units compared
with the most recent assessment performed within the previous 6 months
- Involvement of two new body areas within the previous 6 months
- Elevated acute phase reactants (ESR) >= 30 mm/hr or high-sensitivity C-reactive
protein (hsCRP) >= 6 mg/dL)
- Presence of interstitial lung disease (ILD) and ATA autoantibody positivity
- Modified EUSTAR disease activity index (mDAI) > 2.5
- Participant must be positive for at least one of the following autoantibodies:
- anti-topoisomerase I (ATA) (also known as anti-SCL-70)
- anti-RNA polymerase III (anti-RNAP3)
- anti-nuclear antibody (ANA) (≥ 1:80) Participants who are positive only for ANA
(while being negative for both ATA /anti-RNAP3) will be limited to 30% of the
overall randomized study population.
Key Exclusion Criteria:
- Rheumatic disease other than dcSSc, including limited cutaneous disease (lcSSc) or
sine scleroderma at the screening visit. Secondary Sjogren's disease and scleroderma
myopathy are not exclusionary.
- Positive anti-centromere antibody (ACA+) without positive ATA or anti-RNAP3
autoantibody result at the screening visit
- Previous improvement (decrease) in mRSS > 10 units
- Pulmonary disease with FVC ≤ 50% of predicted or diffusing capacity of the lung for
carbon monoxide (DLCO, corrected for hemoglobin) ≤ 40% of predicted at the screening
visit
- WHO Functional Class 3 or higher assessment for pulmonary arterial hypertension
(PAH, as defined on right heart catheterization), receiving IV therapy for PAH or
evidence of other moderately severe pulmonary disease
- Participants treated with cyclophosphamide within 12 weeks prior to Baseline.
- Prior use of a B-cell depleting therapy other than ianalumab (e.g., rituximab, other
anti-CD20 mAb, anti-CD22 mAb, or anti-CD52 mAb) administered within 36 weeks prior
to randomization, or as long as B cell count is less than the lower limit of normal
or baseline value prior to receipt of B cell-depleting therapy (whichever is lower)
- Treatment with biologic agents, such as intravenous immunoglobulin or monoclonal
antibodies, including marketed drugs, within 12 weeks or 5 half-lives (whichever is
longer) prior to baseline visit, unless explicitly allowed in inclusion criteria
- Treatment with any investigational agent within ≤ 4 weeks (or 5 half-lives of the
investigational drug, whichever is longer) of the baseline visit
- Use of anti-fibrotic agents including colchicine, D-penicillamine, pirfenidone, or
tyrosine kinase inhibitors (e.g., nintedanib, nilotinib, imatinib, dasatinib) in the
4 weeks prior to baseline visit.
- Previous treatment with chlorambucil, bone marrow transplantation or total lymphoid
irradiation.
Other protocol-defined inclusion/exclusion criteria may apply.
