* Increase of \>=3 mRSS units, compared with an assessment performed within the previous 6 months.
* Involvement of one new body area and an increase of \>=2 mRSS units compared with an assessment performed within the previous 6 months.
* Involvement of two new body areas within the previous 6 months.
An area of uninvolved or mildly thickened skin that in the opinion of the investigator would allow subcutaneous injection either at abdomen, front or middle region of the thigh or at outer area of the upper arm.

Participants who are taking mycophenolate mofetil (\<=3,000 mg/day) or equivalent mycophenolate sodium (\<=2160 mg/day) are permitted in the study if the participant has been on a stable dose for \>=3 months at the first dosing day (Day 1) and participant and investigator are willing to continue this dose until at least completion of the Day 85 (Week 12) visit. If mycophenolate was recently ceased, there must be \>=3 months between the date mycophenolate was ceased and the first dosing day (Day 1).
Participants who are taking oral corticosteroids (\<=10 mg/day of prednisone or equivalent) are permitted in the study if the participant has been receiving a dose no greater than 10 mg/day for at least 4 weeks at the first dosing day (Day 1) and the investigator does not anticipate increasing the dose above 10 mg/day during the study.
Participants who are taking phosphodiesterase 5 (PDE5) inhibitors and endothelin receptor antagonists (including bosentan) are permitted in the study if the participant has been on a stable dose for at least 4 weeks for PDE5 inhibitors and for at least 3 months for endothelin antagonists at the first dosing day (Day 1) and participant and investigator are willing to continue this dose until at least completion of the Day 85 (Week 12) visit.
Participants who are taking non-immunosuppressive medications are permitted in the study (e.g. hydroxychloroquine, angiotensin converting enzyme (ACE) inhibitors/angiotensin II receptor (AR) blockers, calcium-channel blockers and proton-pump inhibitors). However no new long-term medications and no dose-changes to existing long term medications are permitted during the two weeks prior to the first dosing day (Day 1).
Male participants must agree to use contraception during the dosing period and for at least 126 days (18 weeks) after the last dose of study treatment and refrain from donating sperm during this period.
A female participant is eligible to participate if she is not pregnant, not breastfeeding, and either she is not a woman of childbearing potential (WOCBP) or she is a WOCBP who agrees to use contraceptives from 28 days prior to first dosing day (Day 1), during the dosing period and for at least 126 days (18 weeks) after the last dose of study treatment.

* History of opportunistic infections that have not resolved by 6 months prior to the first day of dosing (Day1) or recurrent infection as determined by the investigator. This does not include infections that may occur in immunocompetent individuals, such as fungal nail infections or vaginal candidiasis, unless it is of an unusual severity or frequency.
* A serious infection requiring treatment with intravenous antibiotics and/or hospitalization, if the last dose of antibiotics or the hospital discharge date was within 3 months of the first day of dosing (Day1).
