Saphnelo: animal efficacy model or human cells?

anifrolumab · IFNAR1

Efficacy evidence

Mouse surrogate anti-IFNAR1 mAb in spontaneous SLE mouse model (prevented proteinuria)

“The in vivo proof-of-concept was investigated in a mouse disease model of lupus, using a mouse surrogate anti-IFNAR1 mAb.”

✓ VerifiedEMA assessment report, p. 28Source ↗

Why that model

Anifrolumab does not bind murine IFNAR1 or inhibit murine IFN-α

“Anifrolumab does not bind to murine IFNAR1 and does not inhibit the biological activity of murine IFN-α.”

✓ VerifiedEMA assessment report, p. 33Source ↗

Reviewer's view of the efficacy data

EMA: surrogate lupus-model data supported the therapeutic rationale for type I IFN blockade in SLE

“The data generated with a mouse surrogate anti-IFNAR1 mAb in the in vivo proof-of-concept lupus disease models, supported the therapeutic rationale for blockade of type I interferon signalling in the treatment of SLE.”
