Today, Incyte announced that the US FDA has approved its JAK inhibitor Jakafi (ruxolitinib) to expand its indications for the treatment of chronic graft-versus-host disease (GVHD) adults and children over 12 years old
.
These patients have received one or two systemic treatments
This approval is based on the results of a randomized, open-label Phase 3 clinical trial
.
The test results showed that compared with the best existing treatment, the overall response rate (ORR) of hormone-refractory GVHD patients treated with Jakafi at 24 weeks was 49.
GVHD is a potentially fatal complication that may occur after allogeneic stem cell transplantation
.
It is caused by transplanted cells that initiate an immune response and attack the recipient's organs
Jakafi is an oral "first-in-class" JAK1/JAK2 inhibitor
.
JAKs belong to the family of cytoplasmic tyrosine kinases, and their function is to transduce signals mediated by cytokines (such as interferon)
