#How to get 7 days to die alpha 10.4 in 2017 trial
One example is the voluntary withdrawal of gemtuzumab ozogamicin (GO) by the manufacturer (June 2010) from clinical use in the United States based on a negative trial by the Southwest Oncology Group (SWOG) 16.
Prior to 2017, some decisions may have temporarily slowed progress in AML. It is interesting to compare this AML review to the one published in 2016 1, to appreciate the previous “bare cupboard” in AML research and the tremendous progress over such a short period of time. The nihilistic mood that prevailed in the AML community until 2015 has lifted, particularly with research resulting in the FDA approvals of multiple agents for AML since 2017 (Table 1). We will discuss the results with 3 + 7 and put them into context with the more recent combined modality regimens, which may be superior. Many AML experts ascribe to the 3 + 7 regimen as the AML standard of care today others may not. (9) Approaches to enhance T-cell immune responses to AML (as done in ALL) with T-cell engagers (BiTEs), checkpoint inhibitors, and chimeric antigen receptor (CAR)-T-cell approaches. (8) Developing oral anti-AML therapy (e.g., oral decitabine, oral azacitidine) to replace and improve upon the effects of parenteral therapies. (7) Establishing maintenance therapy as an important strategy in AML (as it is in acute lymphoblastic leukemia ). (6) Investigations of combined small-molecule targeted therapies, with or without standard intensive chemotherapy or HMAs (+/− venetoclax at the expense of worsening myelosuppression), in order not only to prolong survival, but also to improve the potential cure rates in previously incurable AML subsets.
(5) Exploring the role of menin inhibitors in mixed-lineage leukemia ( MLL1)-rearranged acute leukemia. (4) Investigations of the roles of APR246 (TP53 modulator) and of magrolimab (anti-CD47 monoclonal antibody enhancing the macrophage-mediated phagocytosis) in TP53-mutated AML. (3) The addition of IDH inhibitors (IDH1 inhibitor ivosidenib IDH2 inhibitor enasidenib) and/or venetoclax in IDH1/2- mutated AML.
(2) The addition of fms-like tyrosine kinase 3 (FLT3) inhibitors (gilteritinib, midostaurin, sorafenib, quizartinib, crenolanib, others) to intensive chemotherapy, or to HMA/low-intensity therapy in FLT3-mutated AML. Ongoing studies and recently approved agents in AML of particular interest include: (1) Combinations of epigenetic therapy with hypomethylating agents (HMAs azacitidine, decitabine) and venetoclax in older patients (or patients unfit for intensive chemotherapy) and combinations of intensive chemotherapy and venetoclax in younger/fit patients.
Research efforts in the last decade have expanded the pathophysiologic-molecular subsets of AML, through identification of prognostic, predictive, and targetable molecular abnormalities 18, 19, 20, 21, 22, 23, 24, 25. In core-binding factor (CBF) AML, adding gemtuzumab ozogamicin (CD33-targeted monoclonal antibody conjugated to the calicheamicin payload) to high-dose cytarabine-based chemotherapy increased the long-term survival rate from 50% to 75+% 13, 14, 15, 16, 17. Chemotherapy-free regimens consisting of all trans-retinoic acid (ATRA) and arsenic trioxide in acute promyelocytic leukemia (APL) resulted in cure rates of 90% 8, 9, 10, 11, 12. Unraveling the heterogeneity of AML at the clinical, cytogenetic, and molecular levels allowed improved prognostic and predictive abilities and led to the development of selected therapies for AML subsets.
