Combo may be option for elderly patients with untreated AML

The CR/CRi rate was 76% among patients with intermediate-risk cytogenetics and 47% among patients with poor-risk cytogenetics.

The CR/CRi rate was 70% among patients older than 75, 52% among patients with secondary AML, 66% among patients with no prior HMA exposure, and 53% in patients with prior HMA exposure.

“Although responses were slightly lower in patients with poor cytogenetic risk, prior HMA exposure, and secondary AML . . ., these responses are far in excess of what we would expect with [LDAC] alone,” Dr Wei said.

“Furthermore, the median time to response was very rapid, and this is extremely important to get patients into remission and avoid the medium-term consequences of active AML.”

The median time to response was 1 month (range, <1 to 9 months).

The 30-day death rate was 3%, the 60-day death rate was 15%, and the median overall survival was approximately 12 months.

Based on these results, AbbVie has initiated a phase 3 trial comparing VEN+LDAC to LDAC alone in elderly patients with untreated AML who are ineligible for intensive chemotherapy.
