Indication

SYLVANT is an interleukin-6 (IL-6) antagonist indicated for the treatment of patients with multicentric Castleman’s disease (MCD) who are human immunodeficiency virus (HIV) negative and human herpesvirus-8 (HHV-8) negative.

Cell Substrate

Human/murine chimeric immunoglobulin G1κ (IgG1κ) monoclonal antibody against human interleukin-6 (hIL-6) produced in a Chinese Hamster Ovary (CHO) cell line.

Manufacturing platform

Siltuximab active substance Final Bulk (FB) is manufactured in a 9-stage process. Briefly, the active substance is obtained by several purification steps (protein A, cation exchange and anion exchange chromatography) from the harvests of one or more CHO cell line bioreactor culture(s). The FB is stored frozen at -40 °C until further processing into the final lyophilized product.

Dose in vial/final container

  • 100 mg of lyophilized powder in a single-use vial.
  • 400 mg of lyophilized powder in a single-use vial.

Dose to patient

Administer as an 11 mg/kg dose given over 1 hour by intravenous infusion every 3 weeks.
