KD025 shows promise for steroid-dependent cGVHD


 

REPORTING FROM THE 2018 BMT TANDEM MEETINGS


In cohort 1, four patients went off the study because of cGVHD progression, and five withdrew, including two who experienced recurrence of their underlying hematologic malignancy. In cohort 2, 7 of the 16 patients experienced progression of cGVHD, he noted.

Patients in cohorts 1 and 2 had a median age of 52 years and had received at least 2 months of steroid treatment and no more than 3 prior lines of therapy. They were comparable with respect to baseline characteristics, including median time to and duration of GVHD, time from diagnosis to enrollment, median prednisone dose, and median number of prior therapies. They had involvement of various – and often multiple – organ systems: 58% had four or more systems affected at the time of enrollment, and 21% had five or more systems affected.

“This, in a way, reflects a real-life mix of the cGVHD population of patients, with some of those patients having advanced cGVHD,” said Dr. Lazaryan.

Responses were observed across all affected organ systems, with complete responses documented in the upper and lower gastrointestinal tracts. About 75% of patients in cohort 1 who had multiple organ systems involved at enrollment demonstrated responses in at least four organ systems.
