Expanded UCB product can stand alone
“There’s a median 10-day reduction in neutrophil recovery [and] 12-day reduction in time to platelet recovery [with NiCord],” Dr Horwitz noted. “There is evidence of robust and durable engraftment with a NiCord unit, with one patient now over 7 years from his first transplant on the pilot trial.”
Relapse, survival, and GVHD
Dr Horwitz reported other outcomes in the NiCord recipients without making comparisons to the CIBMTR matched controls.
The estimated 2-year rate of non-relapse mortality in NiCord recipients was 23.8%, and the estimated 2-year incidence of relapse was 33.2%.
The estimated disease-free survival was 49.1% at 1 year and 43.0% at 2 years. The estimated overall survival was 51.2% at 1 year and 2 years.
At 100 days, the rate of grade 2-4 acute GVHD was 44.0%, and the rate of grade 3-4 acute GVHD was 11.1%.
The estimated 1-year rate of mild to severe chronic GVHD was 40.5%, and the estimated 2-year rate of moderate to severe chronic GVHD was 9.8%.
Dr Horwitz said these “promising results” have led to the launch of a phase 3 registration trial in which researchers are comparing NiCord to standard single or double UCB transplant. The trial is open for accrual.
