How to Source Sarilumab for Pharmaceutical Formulation

Sarilumab (injection (prefilled syringe), 150 mg/1.14 mL, 200 mg/1.14 mL) is classified under Immune Disorder. It is therapeutically aligned with reference brands such as Kevzara (USA/EU). This guide highlights key sourcing factors buyers should consider when procuring high-quality Sarilumab for formulation, R&D, or bulk manufacturing.

Product Overview: Sarilumab is a fully human monoclonal antibody that targets the interleukin‑6 (IL‑6) receptor (both membrane‑bound and soluble forms). By blocking IL‑6 from binding to its receptor, sarilumab inhibits the IL-6 mediated inflammatory signaling pathway.
