Biological Activity

Vedolizumab is a monoclonal antibody binds to integrin α4β7. Vedolizumab blocks the α4β7 integrin, results in gut-selective anti-inflammatory activity. Vedolizumab binds to memory CD4(+) T and B lymphocytes with subnanomolar potency (EC(50) = 0.3-0.4 nM). Vedolizumab also binds to eosinophils at high levels, and to naive T-helper lymphocytes, naive and memory cytotoxic T lymphocytes, B lymphocytes, natural killer cells, and basophils at lower levels. Vedolizumab selectively inhibits adhesion of alpha(4)beta(7)-expressing cells to mucosal addressin cell adhesion molecule 1 (median inhibition concentration [IC(50)] = 0.02-0.06 microg/ml) and fibronectin (IC(50) = 0.02 microg/ml), but not vascular cell adhesion molecule 1.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
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 resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
