Eligibility Criteria

Inclusion

  • Inclusion criteria :
  • Male and female participants ≥18 years of age at the time of signing the informed consent
  • Confirmed diagnosis of primary ITP; for participants who previously received sutimlimab in study TDR16218 (NCT03275454), a response to sutimlimab must have been obtained, as defined by platelet count ≥30 × 10\^9/L on 2 visits at least 7 days apart
  • For participants who have not previously received sutimlimab: persistent/chronic ITP (ITP lasting for ≥6 months) and all the following conditions:
  • Platelet count ≤30 × 10\^9/L on 2 occasions at least 5 days apart during the Screening Period;
  • Lack of an adequate platelet count response (as defined by maintenance of sustained platelet count ≥30 × 109/L in the absence of bleeding) to at least 2 ITP treatments, 1 of which was a thrombopoietin receptor agonist. Other ITP treatments include: IVIg, anti-D immunoglobulin, corticosteroids, splenectomy, rituximab, cyclophosphamide, azathioprine, danazol, cyclosporin A, mycophenolate mofetil, or fostamatinib.
  • If receiving weekly thrombopoietin receptor agonist dosing, the last dose must have been administered ≥7 days before the first dose of BIVV020. If receiving daily thrombopoietin receptor agonist dosing, the last dose must have been administered ≥24 hours before the first dose of BIVV020
  • If applicable, concurrent administration of ITP medications (eg. corticosteroids, IVIg, azathioprine, danazol, cyclosporin A, mycophenolate mofetil, or thrombopoietin receptor agonists) is acceptable provided the participant has been on a stable dose for at least 1 month.
  • If previously dosed with rituximab, the last dose of rituximab must have been administered at least 12 weeks before the first dose of BIVV020
  • Documented vaccinations against encapsulated bacterial pathogens (Neisseria meningitidis, including serogroup B where available, Haemophilus influenzae, and Streptococcus pneumoniae) within 5 years of enrollment
  • Contraceptive use for women of childbearing potential and men who were sexually active with a female partner of childbearing potential
  • Exclusion criteria:
  • Participants were excluded from the study if any of the following criteria apply:
  • Clinically significant medical history or ongoing chronic illness that would jeopardize the safety of the participant or compromise the quality of the data derived from his/her participation in the study
  • Clinical diagnosis of SLE
  • Clinically relevant infection within the month prior to enrollment
  • History of venous or arterial thrombosis within the year prior to enrollment
  • Secondary ITP from any cause including lymphoma, chronic lymphocytic leukemia, and drug-induced thrombocytopenia
  • Positive hepatitis B surface antigen (HBsAg) or active HCV infection
  • HIV infection
  • Pregnant or lactating women
  • Hemoglobin level \<10 g/dL
  • The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
