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:
a) Platelet count =30 × 10^9/L on 2 occasions at least 5 days apart during
the Screening Period;
b) Lack of an adequate platelet count response (as defined by
maintenance of sustained platelet count =30 × 10^9/L in the absence of
bleeding) to at least 2 of the following ITP treatments: IVIg, anti-D
immunoglobulin, corticosteroids, splenectomy, rituximab,
cyclophosphamide, thrombopoietin agonists, azathioprine, danazol,
cyclosporin A, mycophenolate mofetil, or fostamatinib
c) 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
d) If applicable, concurrent administration of ITP medications (eg.
corticosteroids, IVIg, azathioprine, danazol, cyclosporin A, mycophenolate
mofetil, or thrombopoietin receptor agonists) is acceptable provided the
patient has been on a stable dose for at least 1 month.
e) If previously dosed with rituximab, the last dose of rituximab must have
been administered at least 12 weeks before the first dose of BIVV020
