Outline1. Mutationally Targeted Therapies AML
A. FLT3 inhibition• Upfront with 3+7 chemotherapy: Ancillary data from C10603/RATIFY trial• Upfront with 3+7chemotherapy: Crenolanib and gilteritinib• Upfront with HMA: Quizartinib
B. IDH inhibition: IDH1 and IDH inhibitor, in R/R AML, untreated AML, with HMA , with 3+7
2. Immune-based therapies in AMLA. CAR T-cellB. Targeted therapy with antibodies/antibody-like moleculesC. Checkpoint inhibition
3. Other novel therapies in AMLA. Promoting apoptosisB. E-selectin inhibitor
4. ALL: Antibodies, TKIs ( in PH+) and CAR-T cellsAML, Acute myeloid Leukemia; HMA, hypomethylating agent; IDH, isocitrate dehydrogenase; R/R, relapsed or refractory; CAR, chimeric antigen receptor; TKI, tyrosine kinase inhibitor
AML Therapy for Patients Age <60• Standard induction chemotherapy: “3+7”
• Daunorubicin 60 mg/m2/d ‒ 90 mg/m2/d x 3 ‒ Or idarubicin 12 mg/m2d x 3
• Cytarabine 100 mg/m2/d ‒ 200 mg/m2/d x 7 continuous infusion• Ida plus high-dose ara-C (IA) inferior to standard 3+7 (SWOG 1203 study)• Midostaurin 50 mg bid daily 8 ‒ 21 days for mutation FLT3• ? Add GO 3 mg/m2/d 1, 4, and 7
• Postremission (consolidation) therapy• If ELN adverse or CR2: Allogeneic SCT
– Maybe even DUCB or haploidentical SCT• If ELN favorable: (CBF) cytogenetics, or normal cytogenetics with biallelic CEBPa,
or NPM1 mutation and FLT3 ITD wildtype (or low burden): 4 cycles HiDAC; add midostaurin 50 mg bid daily 8 ‒ 21 for mutation FLT3
• If ELN intermediate: Allogeneic SCT if sibling or MUD, otherwise HiDACIf mutant FLT3, add midostaurin in days 8 through 21 of a consolidation cycle
IA, intra-arterial; SWOG, South West Oncology Group; GO, gemtuzumab ozogamicin; ara-C, cytarabine; Ida, intermediate-dose ara-C; SCT, stem cell transplantation; DUCB, double umbilical cord blood; CBF, core binding factor; MUD, matched unrelated donor; HiDAC, high dose ara-c
Therapy of Older Patients With AMLInduction
• Fit, de novo, likely to benefit: ‒ Daunorubicin 60 mg/m2/d ‒ 90 mg/m2/d x 3d + cytosine arabinoside
100 mg/m2/d ‒ 200 mg/m2/d by IVCI for 7 days Add midostaurin days 8 through 21 if FLT3 mutation ? Add GO 3 mg/m2/d 1, 4, and 7
• Fit, secondary (s/p MDS or with MDS-type cytogenetics): ‒ CPX-351
• Unfit (age >70 ‒ 75, PS >2, comorbid double strand)‒ Hypomethylating agent ‒ Consider 10d decitabine in TP53 mutation‒ Consider fractionated GO as single agent
• Postremission therapy‒ RIC allogeneic SCT if feasible‒ ? Repeat induction for others
IVCI, intravenous continuous infusion; MDS, myelodysplastic syndrome; s/p, status post; PS, performance status; RIC, reduced-intensity conditioning
CPX-351 in High-Risk AMLBackground• CPX-351: Liposomal formulation of
cytarabine and daunorubicin packaged at 5:1 molar ratio
• 1 unit = 1.0 mg cytarabine plus 0.44 mg daunorubicin
• Liposomal encapsulation avoids fluctuating drug ratios
• Preferential uptake & intracellular release in leukemic blasts
• Improved efficacy compared to free drug
CPX-351 in High-Risk AMLCPX-351 Clinical Experience
• Phase I (relapsed / refractory AML): MTD 100 U/m2
• Phase 2: Newly diagnosed older AML– Randomized 2:1 CPX-351 or 7+3– Planned analysis: Secondary AML subset: improved RR (57.6%
vs 31.6%, P = .06), EFS and OS• Phase 3: Untreated high-risk AML 60-75 years
– 309 patients randomized to CPX-351 100 U/m2 days 1, 3 & 5 (n=153) v 7+3 (n=156)
– CPX-351 vs 3+7: CR+CRi (47.7% vs. 33.3%; P=0.016), OS (P=0.005), EFS (P=0.021)
– 60-day mortality favored CPX-351 (13.7 vs 21.2%)Lancet JE, et al. Blood. 2014;123(21):3239-3246. Lancet JE, et al. J Clin Oncol. 2016;34(15 suppl): Abstract 7000.

Low Relapse Rate in Younger Patients ≤60 Years Old With Newly Diagnosed FLT3-Mutated Acute
Myeloid Leukemia (AML) Treated With Crenolanib and Cytarabine/Anthracycline Chemotherapy
Abstract 566
Crenolanib is a Highly Selective Type I Tyrosine Kinase Inhibitor of FLT3
Crenolanib Type I inhibitor: Active against both active and inactive conformations
of FLT3 mutations Pan-FLT3 Inhibitor: Active against novel variant FLT3 mutations Overcomes resistance conferring FLT3 mutations, eg. FLT3-D835 High selectivity: No KIT inhibition at clinically achievable levels
(which permits count recovery and no hair depigmentation)

Study Design and Treatment• Phase I study (NCT02236013):
– Multicenter, open-label, 3+3 design– Enrollment began in January 2015
and is ongoing– Adult patients aged ≥18 years with
newly diagnosed AML were enrolled
• Dose-escalation cohorts of 40, 80, and 120 mg/day gilteritinib with 3 – 6 patients per cohort
• More than 20 patients in the dose-expansion cohort, including ≥15 FLT3Mut+ patients
*Gilteritinib was initially administered on days 1 – 14, but the schedule was later changed to administration on days 4 – 17 due to DLTs in the 40 mg/day dose cohort.

• DLT: QTcF prolongation
• In phase I and II studies, composite complete response rate (CRc) ~50% among patients with FLT3-ITD
• Dose-finding study (30 mg v 60 mg): – Similar CRc– Higher ORR (71% v 61%), remission duration (20 wk v 4 wk) and OS

IDH1 and IDH2 MUTATIONS• IDH mutations occur in ~20% of patients with AML
– Most (~85%) occur in diploid or +8 de novo AML– Higher prevalence with increased patient age– Enriched in certain molecularly and
karyotypically defined populations (eg, normal karyotype, mutant-NPM1 AML)
• “Hot-Spot” mutations in enzymatic active site– IDH1-R132, IDH2-R140 or IDH2-R172
• Often considered “founder mutations”– IDH mutations are ancestral in 20% of IDH1 cases
and 35% of IDH2 cases• Can be acquired at time of progression
– 10% - 15% of AML from MDS– 20% - 25% of AML from MPN

IDH1 Inhibitors: Conclusions1. Enasidenib is approved for R/R IDH2-mutant AML
2. Ivosidenib likely will be approved for R/R IDH1-mutant AML
3. Possible role for these ‘differentiating agents” as single agents in chemotherapy unfit mutant-IDH AML
4. The drugs can be given safely with AZA in chemotherapy-unfit IDH-mutant AML: Phase II/III HMA +/- IDHi trials underway
5. The drugs can be given safely with 3+7 in chemo in chemotherapy-fit IDH-mutant AML: Phase III trial planned

GMI-1271 Improves Efficacy and Safety of Chemotherapy in R/R and Newly Diagnosed Older Patients with AML: Results of a Phase
1/2 Study
Abstract 894
DeAngelo DJ, Jonas BA, Liesveld JL, Bixby DL, Advani AS, Marlton P, O'Dwyer M, Magnani JL, Thackray HM, Becker PS
GMI-1271, an E-Selectin Antagonist, Disrupts the Relationship Between Tumor Cells and Bone Marrow Microenvironment
E-selectin:• Constitutively expressed in the bone
marrow microvasculature• Binds to the E-selectin ligand on AML
cells• Promotes cell-adhesion-mediated drug
resistance (CAMDR) of leukemic cell
GMI-1271, an E-selectin antagonist:• Inhibits activation of cancer survival
pathways (eg, NF-KB), disrupting CAMDR within bone marrow microenvironment
• Protects normal HSCs by enhancing quiescence and ability for self renewal
• Reduces chemotherapy-associated mucositisDeAngelo DJ, et al. Blood. 2017;130: Abstract 894.
Phase I/II Study Schema
MEC Induction: mitoxantrone (10 mg/m2/d IV), etoposide (100 mg/m2/d IV), cytarabine (1000 mg/m2/d IV over 60 mins) for 5 daysMEC Consolidation: same, for 4 days
7+3 Induction: cytarabine (200 mg/m2 continuous infusion x 7d), idarubicin (12 mg/m2 x 3d). Day 15 optional reinduction of 5+2 of same IDAC Consolidation: cytarabine (2 g/m2/d IV over 3 hrs QD for 5d), OR cytarabine (1.5 g/m2/dose IV over 3 hrs, BID QOD for 6 doses)
GMI-1271: 5, 10, or 20 mg/kg q 12 hrs in phase I. RP2D was 10 mg/kg

Safety Outcomes: VOD• 19 (18.8%) patients in the inotuzumab group experienced veno-
occlusive disease (VOD) post-transplant; 5 of these cases were fatal– 1 cycle: 7% – 2 cycles: 20% – 3 cycles: 19% – 4–6 cycles: 24% – ≤2 vs ≥3 cycles: 16% vs 21%
• Median time from follow-up SCT to VOD was 15.0 days (range, 3–57 days)
• No difference was seen in median time from last dose to transplant between patients who experienced VOD and those who did not

Leukemia (R/R ALL)Abstract 888

• Approximately 50% of new ALL cases occur in adults aged ≥20 y1
– Although ≈50% of adult ALL patients may achieve long-term survival,2 outcomes for patients with R/R ALL are poor3,4
• The KTE-C19 CAR construct demonstrated an ORR of 82% and a CR rate of 54% in patients with refractory large B-cell lymphomas after a single infusion of CAR-T cells5
• Promising early efficacy and manageable toxicity were also reported with KTE-C19 in adult patients with R/R ALL6
• Here, we report updated safety and efficacy data from patients with R/R ALL in the ZUMA-3 trial (NCT02614066)

Conclusions
New drugs approved in AML 20171. Midostaurin: w/induction chemo, FLT3 mutant upfront2. Enasidenib: single agent, R/R IDH2 mutant3. CPX-351: upfront in secondary AML4. Gemtuzumab: w/chemo, CD33+ upfront or single-agent
relapsed CD33+5. ? 2018, Ivosidenib: single agent, R/R IDH1 mutant
Drugs to watch in AML include venetoclax, GMI-1271, ICPI
ALL: Use of BITE, ADC, and CART changing the approach
