Abstract: Background: IVO is an oral potent inhibitor of mutated IDH1 (IDH1m) enzyme, recently approved for the treatment (Tx) of ND adult patients (pts) with IDH1m AML ≥75 years old or with comorbidities precluding use of intensive induction chemotherapy, and adult pts with relapsed or refractory AML. In this Phase 2 sub-study of the Beat AML Master Trial, we evaluated the efficacy of IVO + AZA combination Tx in ND pts aged ≥60 years with IDH1m AML (ClinicalTrials.gov: NCT03013998) Methods: This open-label multicenter (16 sites / 9 enrolling) combination Tx study enrolled ND pts with R132 mIDH1 AML, utilizing the modified minimax Simon's 2-stage Phase 2 design. Pts received IVO + AZA for 6 cycles in the absence of disease progression (PD), unacceptable toxicity or stem cell transplant. Pts who achieved complete remission (CR)/complete remission with hematologic improvement (CRh)/complete remission with incomplete hematologic recovery (CRi) continued IVO + AZA for a total of 12 cycles, then IVO monotherapy until PD. Pts without CR/CRh/CRi after 6 cycles continued IVO + AZA if they demonstrated Tx benefit, as defined in Figure 1. Key eligibility included ND IDH1 R132 mutated AML pts aged ≥60 years and ECOG performance status 0 - 2 (Karnofsky ≥60). All pts received IVO 500 mg/day orally in continuous 28-day cycles + AZA 75 mg/m2 IV or SC on days 1-7 every 28 days. The primary endpoint was CR+CRh+CRi rate after 6 cycles of Tx. Response was assessed using modified 2017 ELN AML criteria. The modified minimax Simon's 2-stage design required 40 pts and tested the null hypothesis that the CR/CRh/CRi rate equaled 25% vs the alternative of 50% (one-sided alpha = 0.025, power 90%). Stage 1 required & gt;5/16 responses for continued enrollment. Even though these criteria were met, the sponsor decided to discontinue the trial on 12/12/2019. Here we report the final primary endpoint results. Data were frozen 02/03/2021. Results: Between 07/2018 and 11/2019, 19 patients were enrolled with IDH1m AML; 18 started IVO + AZA Tx and are included in the analyses. At data freeze, 5 pts had died and 7 pts still on Tx were offered standard of care IVO. Median age of the pts was 75 years, 50% were ≥75 years, 61% were female and 89% were White (Table 1). The most common reasons for Tx discontinuation were trial discontinued by sponsor (7 or 39%), stem cell transplant (4 or 22%), and PD (3 or 17%). A total of 13 pts achieved CR/CRh/CRi (72%) by up to 6 cycles of Tx (Table 2 & Figure 2). Over the entire study period, 14 pts achieved CR/CRh/CRi (78%) with 8 CR (44%), 3 CRh (17%) and 3 CRi (17%). No deaths occurred within the first 60 days of Tx. After a median follow up of 19.8 months (mos), Page 2 median response duration was not reached, with 12-mos disease-free survival rate of 69%; also, median OS was not reached, with 12- and 18-mos OS rates of 100% and 73%, respectively. The median (range) time on Tx was 12 mos ( & lt;1 - 26.6); 2 pts (11%) discontinued Tx due to an adverse event (AE) - 2 Grade 3 serious AEs (SAEs), differentiation syndrome and skin infection. Overall, 5 pts had 7 Tx-related SAEs; most common Tx-related SAE was differentiation syndrome in 4 pts (22%), of which 3 (17%) were considered Grade ≥3 (Table 3). The most common AEs of any grade (in ≥25% of pts) were diarrhea (61%), constipation (50%), nausea and hypokalemia (each 44%); and most common Grade ≥3 Tx-related AEs were differentiation syndrome and QTc prolongation (each 17%). The most common Tx-related laboratory abnormalities of any grade were decreased platelet count (22%) and decreased WBC count (17%). Conclusions: In ND pts with IDH1m AML and ≥60 years of age, IVO + AZA Tx was associated with a high CR/CRh/CRi rate, no early deaths (60 days) and a 1-year OS of 100%. IVO + AZA was acceptably tolerated and no unexpected toxicities occurred. Most common unique toxicities of IVO observed during the study were differentiation syndrome and QTc prolongation; these led to Tx discontinuation in only 1 pt. CR/CRh/CRi rate obtained with IVO +AZA is higher than that previously reported in studies with the individual agents or intensive chemotherapy approaches, suggesting a synergistic effect. Our overall response rate is similar to that reported recently for IVO + AZA in older ND IDH1 mutant AML pts, despite not including pts with morphologic leukemia-free state and partial remission. Based on these results, a global Phase 3 evaluation of IVO or placebo plus AZA is ongoing (NCT03173248). Figure 1 Figure 1.

Abstract: Background: GILT is an oral potent selective FLT3 kinase inhibitor approved for marketing for the treatment (Tx) of patients (pts) with relapsed/refractory FLT3 mutated (FLT3m) AML but efficacy in older ND FLT3m AML pts is unknown. Furthermore, FLT3m can be present as a dominant or subclone and impact of FLT3 inhibitor therapy in this setting is uncertain. Here we report the results of a Phase 2/1b sub-study of the Beat AML Master Trial to assess the efficacy of GILT monotherapy (GILTm) in ND FLT3m AML pts aged ≥60 years with high and low VAF and the subsequent response-driven addition of DEC Tx. (ClinicalTrials.gov NCT03013998) Methods: The study was an open-label multicenter (15 sites), 3-outcome, 2-stage Phase 2 design that assigned pts to either Dominant FLT3/Group 1 (GP1) or Non-Dominant FLT3/Group 2 (GP2) as shown in Figure 1. Key eligibility criteria included ND FLT3m AML pts with high and low VAF and/or ITD ratio, aged ≥60 years, and ECOG performance status 0-2. In the Phase 2 study, all pts received GILTm 120 mg/day on days 1 - 28. Pts without CR/CRi after cycle 2 were transferred to the Phase 1b study to receive GILT + DEC (Figure 1). Phase 1b study utilized a standard 3+3 design to evaluate the safety/tolerability of concurrent GILT + DEC. Pts received GILT (dose level 1 [DL1] = 80 mg/day or dose level 2 [DL2] = 120 mg/day on days 1-28) + DEC 20 mg/m 2 IV on days 1-10 or 1-5 every 28 days. Primary endpoint was CR+CRi rate (Phase 2). Response was assessed using modified 2017 ELN AML criteria. The non-dominant GP2 was stopped for futility, GP1 was stopped early to modify trial to include venetoclax. Results: Phase 2 - Between 9/10/2018 to 2/11/2020, 19 / 20 enrolled pts (GP1: n = 9; GP2: n = 10) received GILTm and were included in analyses. Baseline pt characteristics are shown in Table 1. Median (range) time on GILTm was 3 cycles (1 - 18) in GP1 and 1 cycle (1 - 9) in GP2. Most common reasons for discontinuing Tx were Tx failure (TF; 44%) and relapse (33%) in GP1 and TF (70%) and disease progression (PD; 20%) in GP2. Overall CR+CRi was achieved in 4 pts (44%) in GP1 and 1 pt (10%) in GP2. Response duration are shown in Table 2. After median follow-up of 14.3 months (mos) and 19 mos in GP1 and GP2, respectively, 1-year OS was 56% and 76%. Most common Grade ≥3 adverse events (AEs) were febrile neutropenia and colitis (each 25%) in GP1; anemia and low platelet count in GP2 (each 30%). Overall, 7 pts had 15 serious AEs (SAEs) and all SAEs occurred in GP1 pts; most common SAE was colitis (25%) and 1 pt (13%) had a Tx-related Grade 3 SAE of tumor lysis syndrome. In GP2, 1 pt (10%) had Tx-related Grade 2 AE of differentiation syndrome. In GP1, 2 pts died within 60 days of Tx and none in GP2. Phase1b - After up to 2 cycles of GILTm, 12 pts with no CR/CRi (GP1: n = 4; GP2: n = 8) were transferred to receive GILT + DEC (Figure 1). At the time of this report, 1 pt with CRh remained on Tx. Median total time on Tx (including GILTm) was 4 cycles and median time on GILT + DEC Tx was 3 cycles (Table 2). Most common reasons for discontinuing Tx were PD (33%) and TF (25%); and 2 pts (17%) stopped Tx due to an AE. Pts were treated with DL1 GILT + DEC (n = 3), then DL2 GILT + DEC (n = 9); only 1 pt had dose-limiting toxicity (DLT) at DL2 (Grade 3 hyperbilirubinemia and pneumonitis requiring steroid therapy), hence, DL2 GILT + DEC was considered the MTD. CR+CRi rate was 25% in 3 pts, all at DL2 (Table 2). After a median follow-up of 17.8 mos, the 1-year OS from start of GILT + DEC Tx was 57%. Most common Grade ≥3 Tx-related AEs were anemia, febrile neutropenia and low WBC count (each 22%). Overall, 6 pts had 12 SAEs; 1 pt with SAE of Grade 4 sepsis died. Three GILT-related SAEs occurred in 1 pt - Grade 3 hyperbilirubinemia, and pneumonitis and Grade 1 transaminases increased. One pt died within 30 days and a second within 60 days of Tx. No difference was observed in GILT pharmacokinetics (PK) with or without DEC, however steady state Ctrough values were 1.4 to 2.3-fold greater than in relapsed/refractory AML pts (Admiral trial). Conclusions: In ND pts ≥60 years old with dominant FLT3 AML, GILTm induced a high 44% CR+CRi rate and long median OS (21.7 mos). Pts with non-dominant FLT3 had low 10% CR+CRi rate. GILTm was generally safe and was associated with differentiation syndrome in 1 pt. Concurrent GILT + DEC was acceptably tolerated, only 1 pt had a DLT, and the MTD was 120 mg/day GILT + DEC. A subset of pts with no CR/CRi during GILTm achieved remission with addition of DEC. Based on these results, a triple combination Tx study with venetoclax is currently enrolling. Figure 1 Figure 1.

Abstract: Background: In vitro studies and emerging clinical data suggest that inhibition of spleen tyrosine kinase may have an antileukemic effect in human AML. Pts with AML and TP53 mutations (TP53m) are commonly associated with older age (≥60 years) and complex karyotype (CK) and respond poorly to standard 7 + 3 induction (IND) chemotherapy with & lt;10% 1-year overall survival (OS). DEC has been reported to improve response in TP53m AML. Here, we report the results of a Phase 2 sub-study of the Beat AML Master Trial that assessed the efficacy of ENTO + DEC combination treatment (Tx) in ND AML patients (pts) with TP53m or CK aged ≥60 years. [ClinicalTrials.gov: NCT03013998] Methods: This multicenter (13 sites), open-label, Phase 2 combination Tx study utilized Simon's 2-stage Phase 2 design and enrolled AML pts with TP53m (identified molecularly) ± CK (Cohort A) or CK (≥3 metaphase abnormalities) without TP53m (Cohort B). Pts initially received 5 days of ENTO lead-in (which was later discontinued), followed by ENTO + DEC and those who achieved CR/CRh/CRi/MLFS with up to 3 cycles of IND proceeded to consolidation (CON) Tx for up to 11 cycles (Figure 1). Pts with CRi/MLFS after IND were allowed up to 6 cycles (IND + CON) to achieve CR/CRh or stayed on Tx if they got clinical benefit or went off Tx. CON was followed by maintenance (MTN) Tx for up to 2 years from start of study Tx. Pts were eligible if aged ≥60 years, ND, and had ECOG performance status 0 - 2. Pts received ENTO 400 mg orally twice daily for 5 days during ENTO lead-in, and then every 28 days during IND, CON, and MTN + DEC 20 mg/m 2 IV days 1-10 (IND) or days 1-5 (CON) every 28 days. Response was assessed using modified 2017 ELN AML criteria. The primary endpoint was composite complete remission (CCR) rate (CR + CRh) with up to 3 cycles of IND, and CRi/MLFS that achieved CR/CRh by up to 6 cycles (IND + CON). Beyond stage 1, pt accrual to Cohort A was allowed based on pts with CRi and to Cohort B was stopped early for futility. Results: Between Oct 2017 and Feb 2020, of the 63 pts enrolled (Cohort A = 48; Cohort B = 15), pts with confirmed eligibility who started study Tx were included in the analyses (Cohort A = 45; Cohort B = 13). During lead-in, 27 pts in Cohort A and 6 pts in Cohort B received ENTOm for 5 days. All pts received ENTO + DEC except 1 pt in Cohort A who withdrew consent (WOC). Median ages of the pts were 70 years (range 60 - 84) in Cohort A and 74 years (range 65 - 86) in Cohort B. Median time (range) on Tx was 2.2 mos and 4.8 mos in Cohort A and B, respectively. Most common reasons for Tx discontinuation were adverse event (AE; 27%), Tx failure (TF; 27%) and WOC (18%) in Cohort A; TF (31%), disease progression and relapse (each 15%) in Cohort B. In each cohort, 1 pt discontinued Tx due to death from leukemia and 1 pt in Cohort A in CRh due to development of an additional genetic abnormality. Four pts (9%) in Cohort A and 1 pt (8%) in Cohort B proceeded to transplant. The CCR (CR + CRh) rates with up to 6 cycles of Tx for Cohort A and B were 13.3% and 30.8%, respectively; overall CR + CRh rates were 17.8% and 38.5% (Table 1). In Cohort A, with a median follow-up of 11.5 months, 0% were 1-year disease-free and median OS (mOS) was 6.5 months. In Cohort B, with a median follow-up of 15.1 months, 25% were 1-year disease-free and mOS was 11.5 months. Deaths within 7-, 30-, and 60-days of Tx were 0, 3 and 11 in Cohort A and 0, 0 and 2 in Cohort B. Most common treatment-related Grade ≥3 AEs in Cohort A and B were febrile neutropenia (31% and 39%) and anemia (22% and 31%) (Table 2). Overall, 83 serious AEs (SAEs) were reported in 33 pts in Cohort A and 12 SAEs in 6 pts in Cohort B; most common SAEs in Cohort A were pneumonia (18%) and respiratory failure (11%), and in Cohort B sepsis, dehydration and acute kidney injury (each 15%). Most common treatment-related grade ≥3 laboratory abnormalities in Cohort A and B were neutrophils decreased (27% and 31%), WBC count decreased (20% and 23%), and lymphocyte count decreased (18% and 15%). Conclusions: ENTO + DEC demonstrated activity in ND AML pts aged ≥60 years with TP53m ± CK and CK without TP53 but induced low CR/CRh rates and short OS consistent with previously published poor CR rates and OS in these pts. Our results differ from the high remission rate and longer OS previously reported for DEC monotherapy in AML pts with TP53m. ENTO + DEC was safe and acceptably tolerated. Novel Tx strategies that can benefit AML pts with these most adverse risk factors are urgently needed. Figure 1 Figure 1. Disclosures Ruppert: Telios Pharma: Consultancy.

Abstract: High‐grade glioma is an aggressive cancer that occurs naturally in pet dogs. Canine high‐grade glioma (cHGG) is treated with radiation, chemotherapy or surgery, but has no curative treatment. Within the past eight years, there have been advances in our imaging and histopathology standards as well as genetic charactereization of cHGG. However, there are only three cHGG cell lines publicly available, all of which were derived from astrocytoma and established using methods involving expansion of tumour cells in vitro on plastic dishes. In order to provide more clinically relevant cell lines for studying cHGG in vitro, the goal of this study was to establish cHGG patient‐derived lines, whereby cancer cells are expanded in vivo by injecting cells into immunocompromized laboratory mice. The cells are then harvested from mice and used for in vitro studies. This method is the standard in the human field and has been shown to minimize the acquisition of genetic alterations and gene expression changes from the original tumour. Through a multi‐institutional collaboration, we describe our methods for establishing two novel cHGG patient‐derived lines, Boo‐HA and Mo‐HO, from a high‐grade astrocytoma and a high‐grade oligodendroglioma, respectively. We compare our novel lines to G06‐A, J3T‐Bg, and SDT‐3G (traditional cHGG cell lines) in terms of proliferation and sensitivity to radiation. We also perform whole genome sequencing and identify an NF1 truncating mutation in Mo‐HO. We report the characterization and availability of these novel patient‐derived lines for use by the veterinary community.
