DAURISMO™ Clinical Studies

14 CLINICAL STUDIES
The efficacy of DAURISMO in combination with low-dose cytarabine was evaluated in a multicenter, open-label, randomized study (Study BRIGHT AML 1003, NCT01546038) that included 115 patients age 55 years or older with newly-diagnosed AML who met at least one of the following criteria: a) age ≥75 years, b) severe cardiac disease, c) baseline Eastern Cooperative Oncology Group (ECOG) performance status of 2, or d) baseline serum creatinine >1.3 mg/dL. Patients were randomized 2:1 to receive DAURISMO at a 100 mg daily dose with low-dose cytarabine 20 mg subcutaneously twice daily on days 1 to 10 of a 28-day cycle (N=77) or low-dose cytarabine alone (N=38) in 28-day cycles until disease progression or unacceptable toxicity. Patients were stratified by cytogenetic risk (good/intermediate or poor).
The baseline demographic and disease characteristics are shown in Table 6. The two treatment arms were generally balanced with respect to the baseline demographics and disease characteristics (see Table 6).

Efficacy was established on the basis of overall survival (OS) from the date of randomization to death from any cause. With a median follow-up of approximately 20 months, the DAURISMO with low-dose cytarabine arm was superior to low-dose cytarabine alone arm (Figure 1). The efficacy results are shown in Table 7. Improvement in OS was consistent across prespecified cytogenetic risk subgroups.
