Treatment for acute myeloid leukemia (AML) generally consists of a combination of
cytarabine and an anthracycline. Although induction therapy leads to complete
remission (CR) for most patients, refractoriness to chemotherapy or relapse after
initial response is associated with poor outcomes. The 1-year survival rates
after first relapse have been reported at 29%, declining to 11% at 5 years.
Prognosis is particularly poor among older patients whose higher prevalence of
unfavorable cytogenetics and high frequency of comorbidities diminish their
ability to tolerate intensive chemotherapy. There is no standard of care for
relapsed/refractory (R/R) AML, and no new therapies have shown consistently
superior outcomes in this setting in over two decades. Vosaroxin is an anticancer
quinolone derivative (AQD) that was evaluated in combination with cytarabine for
the treatment of R/R AML in the randomized, double-blind, placebo-controlled,
phase III VALOR study (n = 711). Compared with placebo/cytarabine, the
vosaroxin/cytarabine regimen demonstrated favorable CR rates and survival in
patients ?60 years of age, with toxicities similar to other AML regimens. Here we
review outcomes of recent studies of commonly used chemotherapy regimens for the
treatment of R/R AML and evaluate the results of the VALOR trial in the context
of the current treatment landscape.
