In Vivo

AMG 369 (0.01-0.1 mg/kg; p.o.; single dose) produces dose-dependent, statistically significant reductions in blood lymphocyte counts at 0.03 mg/kg (45% reduction) and 0.1 mg/kg (65% reduction) 24 hours postdose in female Lewis rats [1].
AMG 369 (0.1 mg/kg; p.o.; single dose) delays the onset and reduces clinical disease severity in a female Lewis rat experimental autoimmune encephalomyelitis model[1].

Animal Model: Lewis rats (female)[1]
Dosage: 0.01 mg/kg; 0.03 mg/kg; 0.1 mg/kg
Administration: p.o.; single dose
Result: Produced a non-statistically significant reduction in blood lymphocytes at 0.01 mg/kg vs vehicle.
Produced a statistically significant 45% reduction in blood lymphocytes at 0.03 mg/kg vs vehicle.
Produced a statistically significant 65% reduction in blood lymphocytes at 0.1 mg/kg vs vehicle, nearly the maximal 70% reduction typically observed with S1P1 agonists.
Animal Model: Lewis rats (female; experimental autoimmune encephalomyelitis model induced by guinea pig myelin basic protein immunization)[1]
Dosage: 0.01 mg/kg; 0.1 mg/kg
Administration: p.o.; single dose
Result: Did not significantly impact clinical disease scores at 0.01 mg/kg vs vehicle.
Delayed disease onset and produced a statistically significant reduction in clinical disease scores at 0.1 mg/kg vs vehicle.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
