Peficitinib (ASP015K) hydrochloride is an orally active JAK inhibitor, with IC50s of 3.9, 5.0, 0.7 and 4.8 nM for JAK1, JAK2, JAK3 and Tyk2, respectively[1]. | [in vivo]
Peficitinib hydrobromide (1-30 mg/kg; p.o.; once daily for 24 days) shows dose-dependent efficacy both in prophylactic and therapeutic dosing regimens in an adjuvant-induced arthritis rat model[1]. | Animal Model: | Seven-weeks-old female Lewis rats, adjuvant-induced arthritis (AIA) model[1] | | Dosage: | 1, 3, 10, and 30 mg/kg | | Administration: | Oral administration, once daily for 24 days | | Result: | Significantly inhibited the increase in paw volume at doses of 1 mg/kg or greater with an ED50 value of 2.7 mg/kg (95% confidence interval: 1.5–4.2 mg/kg). Significantly reduced the bone destruction score at 10 mg/kg or greater and almost fully ameliorated both paw swelling and bone destruction scores at 30 mg/kg.
