Lots of FLT3i action in the first #AML session of the day! Some takeaways. THREAD #ASH20 #leusm
1)Git + chemo: Of pts achieving FLT3 mutational clearance, only ~30% achieve this with induction. Molecular MRD rates increase with consolidation. #HDAC matters. Also, only ~30% of pts transplanted...Do we see the end of allo for FLT3-ITD+ AML? I don’t know yet.
2)Dec/quiz+/-ven: 81% CRc (55% bridged to allo) with triplet in R/R FLT3-ITD+ AML. Myelosuppression manageable with lower dose quiz, 14d ven, D14 BM to eval marrow ablation.
3)Gilt/aza: 67% CRc rate (pretty close to AZA/ven ), DOR 10.4 months. No results from AZA vs gilt/aza randomization yet. Would you enroll a pt to AZA only arm? I don’t think I would.
4)Sequential FLT3 TKI therapy: No real surprises here. Response/survival with FLT3i drops with each successive line of tx. RR to combos is higher. 2nd gen TKI (quiz) > 1st gen (sorafenib), esp in 2nd line.
