Table 2. Response Among Patients With and Without IDH-DS.
Patient Response | IDH-DS, No. (%) (n = 33)a | No IDH-DS, No. (%) (n = 248) |
---|---|---|
Overall responseb | 15 (45.5) | 93 (37.5) |
CR | 6 (18.2) | 49 (19.8) |
CRi/CRp | 6 (18.2) | 16 (6.5) |
PR | 2 (6.1) | 14 (5.7) |
MLFS | 1 (3.0) | 14 (5.7) |
Stable diseasec | 16 (48.5) | 121 (48.8) |
Disease progression | 1 (3.0) | 14 (5.7) |
Abbreviations: CR, complete remission; CRi, CR with incomplete hematologic recovery; CRp, CR with incomplete platelet recovery; IDH-DS, isocitrate dehydrogenase differentiation syndrome; MLFS, morphologic leukemia-free state; PR, partial remission; R/R AML, relapsed/refractory acute myeloid leukemia.
One patient was not evaluable for response; the patient developed IDH-DS on the ninth study day and discontinued treatment before a response assessment.
Investigator-reported overall response rate included CR, CRi/CRp, PR, or MLFS.
No international working group–defined response with no evidence of disease progression, sustained for 56 consecutive days.
