Open Label Extension Study of Brentuximab Vedotin in Early dcSSc
An Open Label Extension Study of Brentuximab Vedotin Treatment in Active Diffuse Cutaneous Systemic Sclerosis (Diffuse Scleroderma)
About This Trial
The purpose of this study is to assess safety and efficacy of Brentuximab vedotin, a CD30-directed antibody-drug conjugate, in patients with active diffuse cutaneous systemic sclerosis (dcSSc) who relapsed after discontinuation of Brentuximab vedotin.
Who May Be Eligible (Plain English)
Who May Qualify:

2. Worsening mRSS of ≥ 4 points as compared to mRSS score at the end of treatment visit (week 48) in the initial study (BV201708).
3. Able to give willing to sign a consent form.
Who Should NOT Join This Trial:
1. Poor pulmonary function (FVC\<40% and/or DLCO\<30%).
2. Pregnancy, breast feeding or child bearing potential without practicing highly effective contraception (and partners for men in the study).
3. Clinically significant pulmonary hypertension requiring drug therapy.
4. Clinically significant cardiac disease.
5. Chronic or ongoing active infectious disease requiring systemic treatment.
6. Seropositivity for human weakened immune system virus (HIV).
7. Active tuberculosis (TB) infection.
8. Active viral infection with viral replication of hepatitis B or C virus.
9. Significant concurrent, uncontrolled medical condition including, but not limited to, renal, hepatic, pancreatic, hematological, gastrointestinal, endocrine, pulmonary, neurological, cerebral or psychiatric disease; and cancer.
10. Peripheral neuropathy at screening Grade 2 or higher.
11. Known or suspected hypersensitivity to components of the treatment
12. Patients known or suspected of not being able to comply with a study protocol (e.g. due to alcoholism, drug dependency or psychological disorder)
13. Any of the following laboratory abnormalities at screening:
- Absolute neutrophils count \<2.0 x 109/L
- Hemoglobin \<85 g/L
- Platelet count \< 100 x 109/L
- AST/SGOT or ALT/SGPT \>2.0 UNL
14. Participation in another clinical trial within six weeks before randomization in this study, with the exception of continuation from the initial study BV201708.
15. Use of rituximab within the previous 4 months.
16. Immunization with a live/ attenuated vaccine less than 4 weeks prior to the baseline visit.
