Shernan Holtan: A positive but negative GVHD prophylaxis story with JAK2i

“A positive but negative GVHD prophylaxis story with JAK2i.

Pacritinib reduced STAT3 in CD4 T cells (met primary endpoint!) and reduced Th1/Th17 cells in the blood at day +21.

However, this biological efficacy did not translate to patient benefit. Clinically, JAK2i did not prevent GVHD.

Humbling.”
