Primary endpoint of ORR by cycle 7, day 1: 75% (59/79) with Niktimvo™ (axatilimab-csfr) at dose 0.3 mg/kg Q2W (95% CI, 64-84).1

profile
The safety and efficacy of Niktimvo were studied in the AGAVE-201 trial, a randomized, open-label, multicenter phase 2 study in patients with cGVHD who had failed 2 or more prior lines of therapy. A total of 79 patients were treated with Niktimvo 0.3 mg/kg Q2W until disease progression, lack of response by 9 months, or unacceptable toxicity.1,6
*As demonstrated in organ responses from the AGAVE-201 trial.
cGVHD=chronic graft-versus-host disease; CI=confidence interval; CSF-1R=colony stimulating factor-1 receptor; MOA=mechanism of action; ORR=overall response rate; Q2W=every 2 weeks.
I think this is a really nice breakthrough in the GVHD treatment landscape. Targeting T- and B-cell pathways is not always sufficient. Having a different pathway to target could be helpful for patients.
