Peficitinib (ASP015K, JNJ-54781532) is an orally bioavailable JAK inhibitor, with IC50s of 3.9, 5.0, 0.7 and 4.8 nM for JAK1, JAK2, JAK3 and Tyk2, respectively. Peficitinib suppresses the IL-2-induced proliferation of human T cells with greater potency than EPO-induced proliferation of human erythroleukemia cells. In human whole blood, ASP015K inhibits STAT5 phosphorylation (pSTAT5).
In vivo, Peficitinib (20 mg/kg, p.o.) suppresses IL-2-induced STAT5 phosphorylation by 78% in the rat model of adjuvant-induced arthritis (AIA). Peficitinib potently inhibits the increase in paw volume (≥1 mg/kg) with an ED50 of 2.7 mg/kg, significantly reduces the bone destruction score (≥10 mg/kg) and almost fully ameliorates both paw swelling and bone destruction scores (30 mg/kg).

| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
