Two different kinds of salvage chemotherapy regimens produced similar outcomes in a study involving 41 individuals with relapsed/refractory acute myeloid leukemia (rrAML). However, 1 treatment was substantially less expensive. Participants with rrAML were treated with either clofarabine- (GCLAC; n=22) or cladribine- (CLAG; n=19) based therapy. Investigators looked at complete response rate, percentage of patients who underwent allogenic stem cell transplant (allo-SCT), relapse free survival, and overall survival. The small trial did not produce statistically significant differences in:
- Complete remission with or without hematologic recovery: 64% for GCLAC, 47% for CLAG.
- Percentage of patient who underwent allo-SCT: 45% and 25%, respectively.
- Relapse-free survival: 1.59 vs 1.03 years, respectively.
- Overall survival: 1.03 vs 0.70 years, respectively.
The average wholesale price was nearly $61,000/patient/cycle for GCLAC, vs nearly $5,000 for CLAG.
