Abstract: Introduction: Despite the successes of treatment with tyrosine kinase inhibitors (TKIs) in patients with CML, allogeneic hematopoietic stem cell transplantation (ASCT) continues to be a potentially curative option for patients with advanced disease of who fail TKI therapy. Here we analyzed outcomes of patients with advanced CML (aCML) (beyond first chronic phase-CP1) who received an ASCT at our institution to identify factors associated with improved survival. Methods:207 consecutive patients withaCML treated at The University of Texas MD Anderson Cancer Center after year 2000 were included. The median age was 44 years (range 2-70 years), 135 (65%) were male, 77% had less than 5% bone marrow (BM) blasts, 129 (65%) had persistentPh-chromosome positive, and 176 patients (85%) were less than a major molecular response at transplant. Forty of 114 tested patients (35%) had resistant BCR-ABL mutations and 10 patients (8.7%) had T315I mutation at transplant. Conditioning regimen wasmyeloablative (MAC) in 140 patients (68%). Donors were matched related (MRD), matched unrelated (MUD),haploidentical (HAPLO), mismatched unrelated (MMUD), umbilical cord blood (UCB) and 1Ag mismatched related (MMRD) in 79 (38%), 75 (36%), 18 (9%), 17 (8%), 11 (5%) and 7 (3%) patients, respectively. The median time from diagnosis to transplant was 27 months (range 1-318 months) while the median follow-up duration was 20 months (range 1-194 months). Results:At 30 days post-transplant, 180 of 200 tested patients (90%) and 134 of 201 tested patients (67%) achieved a complete cytogenetic and at least a major molecular response, respectively. The response to transplant by day 30assessment correlated significantly with the disease status before transplant. A higher percentage of patients who experienced cytogenetic response before transplant experienced molecular response post-transplant (77%) compared with those who did not (61%; p=0.027). For the entire group, the 1-year cumulative incidence (CI) of acute GVHD (aGVHD) grade II-IV and grade III-IV were 41% and 15%, respectively; 5-year CI of extensive chronic GVHD (cGVHD) was 31%.Haploidentical transplant patients had lesscGVHD compared with HLA matched donor transplants (14% vs. 32% for HLA matched transplants). The CI of non-relapse mortality at 100 days and 1 year was 14% and 30%, respectively. Sixty-five patients (31%) had molecular relapse after transplant, which correlated with the degree of disease control before transplant. The CI of cytogenetic and molecular relapse at 5 years was 22% and 31%, respectively. Overall the 5-year survival (OS), progression free survival (PFS) and GVHD-free, relapse-free survival (GRFS)was49%, 34%, and 22%, respectively. Adjusting for all significant measures, percentage of BM blasts before transplant and donor type were significantly associated with PFS and GRFS (Table1, Figure 1).Haplodenticaltransplant patients had longer PFS and GRFS compared with other donor types including matched related or unrelated donor (5-year GRFS for HAPLO, MRD, MUD, MMUD, UCB and MMRD were 53%, 19%, 23%, 29%, 9%, and 0%, respectively; p=0.033) (Table 1, Figure 1). Cytogenetic and molecular response before transplant as well as year of transplant did not predict survival after transplant. Conclusions: ASCT is curative for a proportion of patients withaCML. PFS and GRFS are favorably influenced by percentage of BM blasts and donor type, withhaploidentical donor having at least as good outcomes as HLA matched donors, while molecular and cytogenetic response before transplant do not appear to correlate with survival post-transplant.

Abstract: Background: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is an aggressive hematologic malignancy with historical overall survival (OS) of 8-14 months from diagnosis. Tagraxofusp is a targeted therapy directed to CD123. The US FDA has approved tagraxofusp for the treatment of BPDCN in adult and pediatric patients 2 years and older. CD123 is ubiquitously expressed at high levels on plasmacytoid dendritic cells (pDCs), the cell of origin of BPDCN, and targeting of CD123 with tagraxofusp resulted in high response rates, durable remissions, and a significant proportion of patients bridged to hematopoietic cell transplant (HCT) in first remission (45%). While HCT has the potential to prolong remission of patients with hematologic cancers, relapses after transplantation still occur in patients with certain risk factors including minimal residual disease (MRD). This study is designed to assess the safety and efficacy of tagraxofusp monotherapy as a maintenance treatment in patients with BPDCN post-HCT. The study is open for enrollment and expected to recruit approximately 20 patients. NCT04317781 Rationale: Available data suggest long-term remission can be expected in approximately 50% of patients with BPDCN that undergo allo-HCT. Accordingly, strategies are needed to further reduce the risk of relapse post-HCT. Methods: The study is a Phase 2, single-center, open-label, single-arm clinical trial of tagraxofusp in patients with BPDCN that have undergone HCT. Planned enrollment is 20 patients. Treatment with tagraxofusp will be initiated between day 45 and 120 post-HCT, and dosed days 1-3 in cycles 1-4, and days 1-2 in cycles 5 and beyond. Each treatment cycle is 28 days. Duration of therapy for patients in complete response (CR) or clinical CR (CRc) post-transplant is 24 cycles, with patients who are MRD-positive or remain at high risk of relapse, eligible for continued treatment for as long as they derive benefit. In patients whose post-HCT disease status is either CR with incomplete blood count recovery (CRi) or partial response (PR), treatment will continue until disease progression or unacceptable toxicity. Major Inclusion/Exclusion Criteria : Age ≥18; & gt;30 days post-transplant without active or chronic infections; Karnofsky PS ≥60%; Lansky ≥60; adequate organ function including LVEF ≥ lower limit of normal (LLN); creatinine ≤1.5 mg/dL; albumin ≥3.2 g/dL; bilirubin ≤1.5 upper limit of normal (ULN); AST/ALT ≤2.5 times ULN; and ANC ≥1000. For allo-HCT, no ≥ grade 2 visceral (gut or liver) acute graft versus host disease (GVHD) and no ≥ grade 3 or any other acute GVHD (chronic GVHD allowed at investigator discretion). Key exclusions: Persistent clinically significant non-hematologic toxicities ≥ grade 2; CNS involvement; receiving chemotherapy, radiotherapy, or other anti-cancer therapy within 14 days of first dose of study drug; uncontrolled infection; HIV/Hepatitis B and/or C; and clinically significant cardiopulmonary disease. Endpoints: Primary endpoints include safety and tolerability of tagraxofusp in patients with BPDCN post-HCT, with survival as secondary outcomes.

Abstract: Most patients with multiple myeloma (MM) undergoing autologous hematopoietic stem cell transplantation (autoHCT) eventually relapse, perhaps due to the presence of clonal plasma cells (CPC) in the autograft. We conducted a retrospective analysis to evaluate the impact of CPC in the autograft on the outcomes of high-risk chromosomal abnormalities (HRMM) patients undergoing autoHCT between 2008 and 2018. Patients were divided into CPC+ or CPC− in the autograft by next-generation flow cytometry (NGF). There were 75 CPC + autografts (18%) and 341 CPC− (82%). The CPC + group was less likely to achieve MRD-negative complete remission post-transplant (11% vs. 42%; p   〈  0.001). Median progression free survival (PFS) and overall survival (OS) were (12.8 vs. 32.1 months) and (36.4 vs. 81.2 months) in the CPC + and CPC− groups, respectively (both p   〈  0.001). Also in the subset of patients with MRD-negative ≥VGPR prior to autoHCT, those with CPC + autografts had inferior PFS (HR 4.21, p  = 0.006) and OS (HR 7.04, p  = 0.002) compared to CPC-. In multivariable analysis, the degree of CPC positivity in the autograft was independently predictive of worse PFS (HR 1.50, p  = 0.001) and OS (HR 1.37, p  = 0.001). In conclusion, both the presence and degree of CPC in the autograft were highly predictive of inferior PFS and OS.

Abstract: Background: Peripheral blood hematopoietic stem cell mobilization for autologous hematopoietic stem cell transplantation (auto-HSCT) in multiple myeloma (MM) can be achieved with either growth factors (GF) alone (filgrastim +/- plerixafor), or with chemotherapy (GF + chemo). When utilized, the chemotherapy regimens include single-agent cyclophosphamide (Cy), or combination regimens, including cyclophosphamide, vincristine or bortezomib, doxorubicin, dexamethasone (CVAD/CBAD) at our center. The optimal mobilization strategy, however, has yet to be established. Methods: In this single center retrospective analysis, we identified 1,006 patients who received auto-HCT for MM between 2009 and 2015. This time-period was chosen to include patients who received auto-HCT after the availability of plerixafor. Patients were divided into 4 groups: G (filgrastim alone), G+P (filgrastim + plerixafor), Cy, and CVAD/CBAD. Plerixafor was mainly used "just-in-time", and not as planned therapy in accordance with our Departmental guidelines. Primary endpoints were CD34+ cell dose/kg collected, days to collect the target CD34+ cell dose, time to neutrophil engraftment (first of three consecutive days of peripheral blood neutrophil count of & gt;500 x 106/L), packed red blood cell (PBRC) and platelet transfusion requirement, duration of hospitalization, progression-free survival (PFS), and overall survival (OS). Results: Patient characteristics are summarized in Table 1. There were 654 patients mobilized with G, 203 with G + P, 80 with Cy, and 69 with CVAD/CBAD. Patients mobilized with CVAD/CBAD were younger compared to the other three groups, were less likely to have achieved VGPR to induction, and more likely to have received a more intense preparative regimen (Table 1). Patients who received G alone, G+P, Cy, and CVAD/CBAD collected a median of 4.1 (0.7-12.2), 4.0 (1.8-11.1), 5.2 (2.2-19.2), and 5.6 (2.5-26.6) x106 CD34+ cells/kg [p & lt;0.001]. Median number of days to collect the target CD34+ cell dose of approximately 6x106 were, 3 (1-10), 5 (1-10), 2 (1-8), and 1 (1-8) for G, G+P, Cy and CVAD/CBAD groups, respectively [p & lt;0.001]. Median time to neutrophil engraftment was 11 days in all four groups, with the range being 8-15, 8-14, 8-13 and 9-13 for G, G+P, Cy and CVAD/CBAD respectively [p=0.021] . Median PRBC units transfused after auto-HCT were 1 (0-13), 1 (0-8), 2 (0-7), and 2 (0-9) for patients in G, G+P, Cy, and CVAD/CBAD groups, respectively [p & lt;0.001]. Median platelets units transfused after auto-HCT were 2 in all four groups. Median duration of hospitalization for auto-HCT was 17 (3-73), 18 (5-84), 18 (4-3 9), and 19 (5-34) days in G, G+P, Cy and CVAD/CBAD groups, respectively [p=0.003]. The 5-year [95% CI] PFS rates were 36.6% [32.9-40.7%], 38.5% [31.5-47%] , 28.9% [20.0-41.5%], and 30.9% [21.5-44.3%] for G, G+P, Cy, and CVAD/CBAD groups, respectively. The 5-year [95% CI] OS rates were 71.3% [67.7-75.1%] , 73.9% [67.3-81.2%], 67.6% [57.3-79.7%] , and 61.7% [51.1-74.5%] for G, G+P, Cy, and CVAD/CBAD groups, respectively. On multivariable analysis, after adjusting for covariates including age, ISS stage, cytogenetic risk, and response to induction, there was no significant impact of mobilization approach on PFS or OS. Conclusion: Approximately 85% of MM patients underwent PBSC mobilization with GF only (G or G+P). GF + chemo (Cy, CVAD/CBAD) was primarily used in patients with suboptimal response to induction, and allowed successful PBSC collection in this high-risk group. GF + chemo-based mobilization was associated with a higher CD34+ cell dose collection, without improving the time to neutrophil or platelet engraftment, PRBC or platelet transfusion requirement, or the duration of hospitalization.

Abstract: Introduction Outcomes after allogeneic stem cell transplant (AHSCT) are influenced by both disease and patient related factors. We hypothesized that combining hematopoietic stem cell transplant comorbidity-age index (HCT-CI/Age) and the refined disease risk index (DRI-R) would better predict survival post-transplant and developed a hematopoietic cell Transplant-composite risk (HCT-CR) model, which we tested in a group of patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) treated at MD Anderson Cancer Center (MDACC). Methods The study included consecutively treated patients, 18 years of age or older, with AML and MDS who received first AHSCT at MDACC between 2005-2016. Donors were HLA-matched related (MRD), HLA-matched unrelated (MUD), 9/10 MUD (MMUD), haploidentical (HAPLO) and 9/10 MRD (MMRD). To develop this model, patients were assigned into 4 groups: 1. Patients with low/intermediate DRI-R and HCT-CI/Age 〈 /=3 (low-risk); 2. Patients with low/intermediate DRI-R and HCT-CI/Age 〉 3 (intermediate-risk); 3. Patients with high/very high DRI-R and HCT-CI/Age 〈 /=3 (high-risk); and 4. Patients with high/very high DRI-R and HCT-CI/Age 〉 3 (very high-risk). Primary endpoint was 5-year overall survival (OS); other outcomes assess were progression-free survival (PFS), non-relapse mortality (NRM) and relapse rate. The stability of the HCT-CR model was tested by bootstrap resampling. The discrimination power of the HCT-CR model on OS was compared with that of the DRI-R, HCT-CI/Age and cytogenetic risk model by the Harrell C-concordance index. Results The analysis included 942 patients (492 male and 450 female) with a median age of 53 years (range 18-65 years). Cytogenetic data at diagnosis was available in 928 (98.5%) patients and was favorable, intermediate and adverse cytogenetic risk in 63 (7%), 523 (56%) and 342 (37%), respectively. Fifty-five (6%), 399 (43%), 392 (42%) and 82 (9%) patients had low, intermediate, high and very high DRI-R, respectively. The HCT-CI/Age was available in 922 (98%) patients with the median score of 3 (range 0-18). Donor types included MRD (n=377), MUD (n=416), MMUD (n=68), HAPLO (n=73) and MMRD (N=8). Using the HCT-CR model, patients were stratified into 4 risk groups: low (N=272), intermediate (N=168), high (N=284) and very high-risk (N=184), with significantly different survival. The 5-year OS rates for patients in low, intermediate, high and very high-risk group were 57%, 48%, 34%, and 26%, respectively (P 〈 0.001) (Figure 1). The probability of 5-year PFS rates were 55%, 46%, 30% and 23% for these 4 risk groups, respectively (P 〈 0.001). Post-transplant outcomes of all 4 HCR-CR groups are summarized in Table 1. Compared with the low HCT-CR risk group, patients with intermediate, high and very high-risk group had a significantly increased risk of death with HR of 1.42 (95%CI 1.06-1.91; P=0.02), 2.11 (95%CI 1.65-2.70; P 〈 0.001), and 3.02 (95%CI 2.32-3.92; P 〈 0.001), respectively. The significant association between OS and the HCT-CR groups persisted after adjusting for potential confounders with adjusted HR of 1.37 (95%CI 1.02-1.85) for intermediate, 2.08 (95%CI 1.62-2.67) for high and 2.92 (95%CI 2.23-3.82) for very high-risk group when compared with low risk group. The stability of the hematopoietic cell transplant - composite risk model was confirmed in a bootstrap resampling procedure. Among 500 new datasets, on average, patients in intermediate, high and very high-risk group had significantly increased risk of death after transplant when compared with low risk group with HR of 1.39, 2.11 and 2.98, respectively. Results from the concordance test showed that the HCT-CR model provided better discriminative capacity for prediction of OS when compared with DRI-R, HCT-CI/Age and cytogenetic risk group models with C-index of 0.62 versus 0.60, 0.54 and 0.55, respectively. The goodness of fit test showed that the HCT-CR model fit the data significantly better than the other models (P 〈 0.001). Conclusion Combining disease and patient-related factors provides better survival stratification for patients with AML/MDS receiving AHSCT. This novel HCT-CR model will be validated in patients with all diseases undergoing allogeneic hematopoietic stem cell transplantation and results will be presented at the meeting.

Abstract: 7047 Background: BCL-2 inhibitor Ven has shown a promising benefit in pts with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). There is paucity of information about the safety and efficacy of alloSCT post Ven. Methods: We conducted a retrospective analysis of 35 AML/ALL pts who received alloSCT following Ven-based therapies between 2013-2018 at MDA. Results: Median age at alloSCT was 60 years and 15 (43%) pts had an age-adjusted HCT-CI score ≥ 4. Disease diagnosis – AML (n = 31; 89%), ALL (n = 4; 11%). Disease status at transplant was CR1 (n = 17; 49%), CR2/CR3 (n = 9; 26%) or refractory (n = 9; 26%). 20/26 (77%) CR pts were MRD-negative. Median # of prior therapies was 2 (range 1-7) and 4 (11%) pts had failed a prior alloSCT. AML pts were classified by ELN 2017 criteria to have favorable, intermediate and adverse risks in 16%, 23% and 61% respectively. Ven was provided in combination of hypomethylating agents (HMA) or other chemotherapies in 26 (74%) and 9 (26%) pts, respectively. Among pts treated with Ven + HMA, some also received IDH1/2 inhibitors (n = 7, 20%), FLT3 inhibitors (n = 4; 11%) or anti-PD1 (n = 3, 9%). Median duration of Ven-based treatment was 2 months (range 0.5- 4.6). Ven was discontinued in 6 (17%) pts due to adverse events (n = 4) or progression (n = 2); the remaining pts (83%) continued their Ven-therapy as a bridge to alloSCT. The median time from last Ven dose and transplant was 26 days. Conditioning regimens were melphalan-based reduced intensity (n = 26, 74%), or busulfan-based myeloablative regimens (n = 9; 26%). Donor source was matched -unrelated (n = 14, 40%), -related (n = 9; 26%) or haplo- (n = 12; 34%). GVHD prophylaxis consisted of tacrolimus with either PT-Cy in 25 (71%) pts or methotrexate in 10 (29%) pts. All pts engrafted (median day 30 donor cells = 100%). Median days to ANC 〉 500 and platelets 〉 20K was 15.5 and 22.5, respectively. With a median follow up of 5.7 months (range 0.7-15.4), the 1-year rates of OS, PFS, and NRM were 71%, 63% and 3% respectively. CI of acute grade 2-4 and 3-4 GVHD were 26% and 3% respectively. Four pts died: 3 because of disease relapse and 1 of infection. Conclusions: AlloSCT is a safe and feasible consolidation treatment option in acute leukemia pts who were pre- treated with Ven, without excessive risk of NRM or acute GVHD. Larger prospective studies are required to validate our observations.
