No significant modulation of CD4/CD8 T cells, NK cells or mature B cells in 26-week monkey study
“In addition, the 26-week study included an immunophenotyping assessment which indicated that tralokinumab did not significantly modulate any of the immune cell populations investigated which including CD4 and CD8 T cells, NK cells and mature B cells.”
Low circulating IL-13 in naive monkeys may mask pharmacological effects, limiting predictivity
“Whilst there were no apparent tralokinumab related effects in these studies, this could be explained by very low circulating IL-13 levels in naïve monkeys.”
In vitro whole-blood cytokine release far below alemtuzumab/TGN1412 controls; no effects on monkey TDAR, lymphocyte subsets or serum cytokines; ADA in some monkeys
