Abstract Background: Myelofibrosis (MF) is a myeloproliferative neoplasm that is characterized by significant scar tissue and fibrosis in the bone marrow, enlarged spleen and/or liver from extramedullary hematopoiesis, and may include significant constitutional symptoms such as bone pain, night sweats, pruritis, and cachexia. The only curative therapy is allogeneic stem cell transplant. Although the symptom burden has been explored in the literature, the impact of hematopoietic stem cell transplant (HCST) on QoL in patients with MF has not been evaluated. We sought to longitudinally describe QoL in patients undergoing HCST for MF. Methods: We prospectively followed patients undergoing HSCT for MF. We assessed symptoms, functioning, and QoL using the FACT-BMT and MPN-SAF total symptom score (TSS) pre-transplant and at day 30, day 100 and one year post-transplant. Scores at the post-transplant time points were compared with baseline scores by paired t-tests. Pearson correlations between FACT-BMT and MPN-SAF TSS questionnaires were also computed. Results: 16 patients were enrolled [median age 64.0 (49-69) years; 13 (81%) male; 13 (81%) Caucasian], two did not have day 30 data as they died prior to then or did not go to transplant. Fourteen patients had day 30 information, 11 had day 100 information, and only 4 had one year information. Of the 14 who had day 30 information, 6 patients died within the first year, two from treatment related mortality and four from relapse. One patient had intermediate-1 risk, the remainder of the patients were intermediate-2 or high risk. All patients had RIC conditioning. Mean MPN-SAF TSS score was 28.1 (SD=14.2) and FACT-BMT total score was 99.8 (SD=17.4) at baseline. FACT-BMT and MPN-SAF TSS at baseline were inversely correlated; lower symptom score was associated with higher QoL (r=-0.62; p=0.01). FACT-BMT at day 30 was lower (mean change: -12.5, SD=16.7; p=0.03). Two MF-specific symptoms showed improvement that reached statistical significance compared to baseline: night sweats mean improvement day 30, 2.5 (SD=3.1; p=0.01) and mean improvement day 100, 1.7 (SD=2.6; p=0.05, Figure 1); headache mean improvement day 100, 1.5 (SD=1.9) p=0.02. In general, scores showed a worsening at day 30, improvement at day 100 and stability at one year. The MPN-SAF TSS worsened at day 30 (6 points) and improved by day 100 (4.5 points). Changes that showed improvement at day 100 include Brief Fatigue Inventory (BFI) with a mean improvement of 1.2 points and concentration (1 point). Of the four surveys that were collected at one year, a modest decline was noted in BFI (1.5 points), inactivity (1.5 points) and cough (3 points). However improvements were noted in night sweats (2.25 points), abdominal discomfort (1 point), insomnia (1.75 points), bone pain (1 point). Discussion: This is the first study to evaluate serially the QoL and symptom burden of patients who underwent a transplant for MF. A decline in QoL in the first 30 days was observed, with modest improvement at day 100. Few surveys have been completed at 1 year to date in this ongoing study. Collection of surveys past one year may be more informative regarding long-term impact of transplant on quality of life. Figure 1 Figure 1.

Introduction Up-regulation of inhibitory receptors, such as programmed death-1 (PD-1), is an integral component of acute myeloid leukemia (AML) immune evasion, chemotherapy resistance, and disease progression. Early phase clinical trials investigating immune checkpoint inhibitors (ICIs) in patients with AML have demonstrated promising findings. We previously reported that pembrolizumab administration on day 14 after high-dose cytarabine (HiDAC) salvage chemotherapy in patients with relapsed/refractory (R/R) AML was safe, feasible, and associated with encouraging clinical outcomes. PD-1 blockade prior to allogeneic stem cell transplant (alloSCT) has been associated with increased risks of alloSCT-related toxicity in lymphoma. AlloSCT remains the most established treatment paradigm for curative intent in AML patients who achieve a complete response (CR); however, there are limited data on the clinical outcomes and safety of ICI prior to alloSCT in AML. We set out to compare clinical outcomes of AML patients receiving pembrolizumab prior to alloSCT versus a control group of AML patients receiving alloSCT without prior ICI exposure. Methods We assessed clinical outcomes of patients who enrolled on a phase II clinical trial of HiDAC followed by pembrolizumab 200 mg IV on day 14 (NCT02768792) for R/R AML and subsequently underwent an alloSCT. Date of alloSCT was required to be >30 days from last dose of pembrolizumab. We matched each trial participant who underwent an alloSCT in a 1:2 ratio with controls who received alloSCT at our institution since 2016. Patients were matched on age, sex, age-adjusted hematopoietic cell transplantation-comorbidity index (HCT-CI), donor type, and conditioning intensity. The nonparametric Jonckheere-Terpstra test was used to test for a difference in the ordered severity categories of acute graft versus host disease (aGVHD) within 100 days of transplant. The time-to-event estimates for overall survival (OS) and relapse-free survival (RFS, event is either death or relapse) were calculated using the Kaplan-Meier method and compared using a log rank test. Results Nine out of 37 (24.3%) R/R AML patients treated with HiDAC followed by pembrolizumab received an alloSCT. Baseline characteristics of the R/R AML patients who received pembrolizumab versus R/R AML controls who underwent alloSCT are described in Table 1. One patient in each cohort received an alloSCT with evidence of active disease by flow cytometry (>5% blasts) or hematopathology IHC evaluation, whereas all other patients in both arms were in CR/CRi or MLFS at the time of alloSCT. The pattern of aGVHD severity was similar with the exception of 3 control patients (3/18 or 17%) having grade III-IV aGVHD versus 0/9 pembrolizumab patients (p = 0.92). Notably, 7/9 (78%) patients in the pembrolizumab cohort had no evidence of chronic GVHD. There was a nonsignificant increase in relapses (6/9: 67% vs. 6/18: 33%; p = 0.22) and deaths (6/9: 67% vs. 8/18: 44%, p = 0.42) in pembrolizumab versus control patients, respectively. The median follow-up for survivors was 23 months. Median OS was 21 months for pembrolizumab cohort versus 25 months for control patients. One-year OS was 67% (95% CI, 28%-87%) for pembrolizumab patients versus 78% (95% CI, 51%-91%) for control patients, p = 0.34. One-year RFS was 44% (95% CI, 14%-72%) for pembrolizumab patients versus 67% (95% CI, 40%-83%) for control patients, p = 0.14. Conclusion Treatment with ICI represents a promising therapeutic strategy for AML. Among a cohort of patients treated with HiDAC followed by pembrolizumab for R/R AML, alloSCT appeared to be feasible without increased risk of GVHD or early mortality. Although a small number of patients received alloSCT after pembrolizumab, OS appeared comparable to R/R AML controls who did not receive ICI. The increase in relapse rates seen in the pembrolizumab cohort may have been impacted by the higher proportion of patients with measurable residual disease (MRD) prior to alloSCT (78% vs. 39%, respectively). These data warrant further investigation of ICI prior to and after alloSCT in high-risk AML patients. Disclosures Tschernia: AstraZeneca: Research Funding.

Abstract Background: Myelofibrosis (MF) is a bone marrow disorder characterized by anemia, splenomegaly and constitutional symptoms. There has been substantial work documenting quality of life (QoL) in patients with MF, however, very little data about patients following allogeneic stem cell transplant (alloSCT) for MF. Many patients decline alloSCT due to concerns secondary to QoL. Methods: Medical facts and patient reported outcomes (PRO) measures were collected within a month prior to transplant, at day 30, 100 and 1 year post alloSCT. PRO measures include Brief Fatigue Inventory, Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), global assessment of change and the Myeloproliferative Neoplasms Symptom Assessment Form (MPN-SAF). The group was measured as a whole, and the patients in the upper quartile of MPN-TSS (the aggregate score of the 10 core items of the MPN-SAF) were also considered. Results: Fifty patients were enrolled on this study, 47 who proceeded with transplant. The median age of the patients was 63, ranging from 35-74. The majority of the patients were male (29, 66%), and Caucasian (43 (96%)). Most patients had primary MF (26, 59%), 9 patients had post-PV MF, and 9 patients had post-ET MF. Twenty patients had DIPSS Intermediate 2 risk disease, and 16 had DIPSS high risk disease. Twenty-six (51%) had a matched unrelated donor, 12 (30%) had a matched related donor and 5 (12%) had a mismatched unrelated donor. The majority of the patients had RIC regimens (35, 88%). At baseline the mean MPN-TSS was 27.7 (out of possible 100), and at day 30, day 100 and 1 year it was 24.6, 32.0, and 25.0, which reflected no significant change between the time points. Interestingly, all the MPN specific symptoms (including fevers, night sweats, pruritis, abdominal pain) had a significant improvement at least one time point following alloSCT. Patients in the highest quartile based on baseline TSS score (12 patients with scores at baseline greater than or equal to 37), had significant improvement in TSS score at day 100, headache at day 30, insomnia at day 100, night sweats at day 100, itching at day 100 and overall QOL at day 100. With regards to the FACT BMT, as would be expected, there was a significant decline in the FACT BMT total score, as well as trial outcome index (TOI) at day 30, but a return to close to baseline by one year. In the global assessment of change, on day 30, 11 (27.5%) of patients reported feeling a little/moderately/very much better overall quality of life since their transplant and 27 (67.5%) felt a little/moderately/very much worse quality of life. At day 100, 11 (31.4%) reported better quality of life and 20 (57%) reported worsening since transplant. By one year, 17 (60.7%) reported feeling better and 7 (25%) reported worsening. These findings did not appear to have a correlation with presence or absence of graft versus host disease. We were unable to assess the impact of conditioning as the majority of the patients had RIC conditioning. Discussion/ Conclusions: Our study evaluated the quality of life in patients with myelofibrosis who have undergone bone marrow transplantation. We have shown that there is very little change in symptom burden over the first year following transplant in general; however, significant improvement was observed in MF specific symptoms, and in patients who had a high symptom burden at baseline. By one year 61% felt that their QoL was better than it was prior to transplant. Our findings suggest that many of the patients do not experience a significant decline in QoL at 1 year after alloSCT, and actually report that their QoL improves. Further investigation is required to validate these findings. Figure. Figure. Disclosures Palmer: Novartis: Research Funding. Dueck:Phytogine: Employment; Pfizer: Honoraria; Bayer: Employment.

Abstract Abstract 837 Background: Combination therapy with cytotoxic chemotherapy and tyrosine kinase inhibitors has improved the outcome for patients with Ph+ ALL with durable remissions in some patients even without an allogeneic stem cell transplant. The dual Src and Abl inhibitor dasatinib has ∼325 times more potent in vitro kinase inhibition than imatinib against BCR-ABL with significant clinical activity in patients with imatinib-resistant lymphoid blast phase CML (CML-LB) and Ph+ ALL. Aim: To determine the efficacy and safety of combining chemotherapy with dasatinib for treating patients with Ph+ ALL. Methods: In this phase II trial, patients with newly diagnosed Ph+ ALL receive dasatinib 50 mg po bid (or 100 mg daily) for the first 14 days of each of 8 cycles of alternating hyperCVAD and high dose cytarabine and methotrexate. Patients in CR continue to receive maintenance dasatinib 50 mg po bid (or 100 mg daily) and vincristine and prednisone monthly for 2 years followed by dasatinib indefinitely. Results: We have enrolled in the study 34 patients with untreated Ph+ ALL and 7 patients with 1 prior cycle of chemotherapy (before Ph+/BCR-ABL+ status was known). Patients younger than 50 years old have received a median of 6 cycles (range 2-8) and patients 50 years and older have received a median of 6 cycles (range 1-8). 20 patients are receiving maintenance in CR and two have completed the entire treatment regimen. Median age is 51 years (range 21 – 79); 22 patients were older than 50 years, Median WBC at diagnosis was 13.6 × 109/L (range, 1-276 × 109/L). 12 patients had CNS involvement at presentation. All patients are evaluable for assessment of response to induction; 39 (95%) achieved CR after first cycle or were CR at start. Two patients died before response assessment from infections. Thirty-one of 39 (79%) evaluable patients achieved cytogenetic (CG) CR after 1 cycle; 4 had a major CG response (3 had 5% and one had 15% Ph+), 2 had insufficient metaphases, and 2 are unknown (no CG exam on day 21 marrow). To date, 22 patients (56%) have achieved complete molecular remission (CMR) and another 8 (21%) have achieved a major (but not complete) molecular response (MMR) at a median of 14 weeks from initiation of treatment (range 2 – 59 weeks). Minimal residual disease assessment by flow cytometry is negative in 35 (90%) patients at a median of 3 weeks (range, 2-18 weeks). The median time to neutrophil and platelet recovery for cycle 1 is 18 and 23 days and for subsequent cycles is 15 and 20 days. Grade 3 and 4 adverse events have included bleeding (GI, GU, soft tissue and subdural hematomas)(18), pleural effusions (9), pericardial effusion (1), reversible rise in creatinine (10), deep vein thromboses (6), pulmonary emboli (3), as well as diarrhea, infections, hypophosphatemia, hypokalemia, hypocalcemia, hyperglycemia, and elevated transaminases. With a median follow up of 13 months (range 1-33), 29 patients (71%) are alive and 27 (66%) are in CR; 4 patients died in CR; 1 from an unrelated cardiac event and 3 from infections. Three patients have undergone an allogeneic stem cell transplant. The median disease free survival is 48+ weeks (range,1 to 140+) and the median overall survival is 52+ weeks (range, 3 to 143+). Eight patients have relapsed with a median response duration of 51 weeks (range 23-73) and 6 of them have died. In 5 patients morphological relapse was preceded by flow and molecular relapse. Five relapsed patients had ABL mutations (3 T315I, 1 F359V, and 1 V299L). Conclusion: Combination of chemotherapy with dasatinib is effective in achieving long term remissions in patients with newly diagnosed Ph+ ALL.

Abstract Introduction: Acute myeloid leukemia (AML) is heterogenous disease with a range of cytogenetic and molecular changes. Several molecular mutations identified in AML patients at diagnosis have prognostic implications and play important roles in guiding induction and consolidative treatment decisions. The prognostic impact of mutations peri allogeneic stem cell transplant are less well characterized. In this study, we examine the significance of pre and by D100 Post-transplant mutation status in AML patients underwent Fludarabine/Melphalan conditioned reduced intensity allogeneic stem cell transplant (SCT). Methods: AML patients who are in morphologic complete remission (CR1 or greater) with available molecular mutation at diagnosis, within 6 weeks prior to allogeneic SCT, and by 100 days post-transplant were included. Variables analyzed included baseline demographics, clinical variables (CIBMTR disease risk index (DRI), type of transplant, ELN risk, performance status) and 23 recurring molecular mutations. Analysis was also performed by grouping mutations into six pre-defined gene groups based on gene function (Table 2). Multivariable cox regression analysis was adjusted for age, gender, DRI and molecular mutation. Backward selection method was used to select the best combination of genes that is associated with overall survival (OS) and relapse-free survival (RFS). Results : A total of 142 AML patients with molecular genetic data available from 2014 to June, 2020 at Weill Cornell Medicine/New York Presbyterian Hospital were analyzed. Clinical characteristics of the patients are summarized in Table 1. The median age was 58 years (range 20 -78). Total of 261 mutations were detectable at diagnosis (Table 3). Prior to allo SCT and by D100, the detectable mutations were 87 and 40 respectively, which represent 56 and 26 patients. High-dose chemotherapy was less effective on clearing DNMT3A, ASXL1, TET2 (DAT) or IDH mutations, resulting in over-representation of DAT and IDH mutations prior to transplant. With a median follow-up time of 25 months, the median overall survival for the group was 40.8 months. The presence of mutations in TP53 at diagnosis was associated with worse OS by both univariate (HR 3.67, p=0.0030, CI 1.56-8.68) and multivariate analysis (HR 4.75, p=0.0014, CI 1.82-12.39) with median OS reduced from 49.3 to 19.3 months (p=0.002). High CIBMTR DRI (HR 0.17, p=0.0018, CI 0.05-0.51) predicted reduced OS and RFS, and Age >60 at diagnosis was associated with worse OS (HR 1.7 CI 1.04-3, p 0.03). Presence of any molecular mutation prior to transplant did not impact OS or RFS. For patients with any persistent mutations by D100 post-transplant, both OS ( HR 2.04, p 0.027, CI 1.08-3.8) and RFS (HR 1.99, p 0.025, CI 1.09-3.6,) were reduced in the univariate analysis, but not on multivariate analysis (HR 1.88, p 0.5, CI 0.99-3.49). Analysis based on six mutational groups (table 2) did not show any difference in their OS or RFS. However, worse RFS was independently associated with persistent IDH1 (HR 3.8, p 0.004, CI 1.07-56,), TET2 (HR 3.9, P 0.04, CI 1.04-14.1), and FLT3-ITD (HR 4.5, p 0.01, CI 1.7-52). Worse OS was independently associated with persistent TET2 (HR 3.9, p 0.013, CI 1.04-14.1), with a trend towards worse OS for IDH1, FLT3-ITD, with a trend towards worsening OS and RFS for ASXL1 (OS HR 7.4, p 0.06, CI 0.86 -63; RFS HR 4.9, p 0.06, CI 0.9-26) and DNMT3A (OS HR 2.3, p 0.12, CI 0.86-6.9; RFS 2.9, p 0.08, CI 0.98-8). Association with worse clinical outcomes remained significant after multivariate analysis for TET2 (both OS HR 3.98 p 0.041, CI1.07- 32 and RFS HR 5.8, p 0.032, CI 1.1- 29), IDH1 (RFS HR 8.02, p 0.049, CI 1.02 - 65) and FLT3-ITD (RFS HR 11.4, p0.010, CI 2.2- 80). Conclusions: Presence of TP53 mutations was associated with worse OS. Presence of pre-transplant mutation did not impact RFS or OS. Persistent presence of mutations in TET2, IDH1 and FLT3-ITD after Fludarabine/melphalan conditioning regimen allogeneic SCT were associated with shorter RFS and OS (in the case of TET2) independent of CIBMTR DRI. This analysis supports association of adverse outcomes in AML patients with selected persistent mutations by D100 post-transplant in reduced intensity transplant setting. Post-transplant strategies that can further eliminate persistent mutations should be investigated in prospective studies. Figure 1 Figure 1.

Abstract Background The dual Src and Abl inhibitor dasatinib has significant in vitro kinase inhibition against wild-type and mutant BCR-ABL, and significant clinical activity in patients with imatinib-resistant lymphoid blast phase CML (CML-LB) and Philadelphia-chromosome positive (Ph+) acute lymphoblastic leukemia (ALL). Aim To determine the long-term efficacy of the combination of the hyperCVAD regimen with dasatinib for treating patients with Ph+ ALL. Methods In this phase II trial, patients with newly diagnosed Ph+ ALL received dasatinib 50 mg po bid (or 100 mg daily) for the first 14 days of each of 8 cycles of alternating hyperCVAD and high dose cytarabine and methotrexate (induction/consolidation cycles). After 42 patients, the protocol was amended to give dasatinib 100 mg daily in the first 14 days of the first cycle and then 70 mg daily continuously from the second cycle. Patients in complete remission (CR) continued to receive maintenance dasatinib 50 mg po bid (or 100 mg daily) and vincristine and prednisone monthly for 2 years followed by dasatinib indefinitely. Patients eligible for allogeneic stem cell transplant proceeded to it in first CR. Results 63 patients with untreated Ph+ ALL and 9 patients with 1 or 2 prior cycles of chemotherapy (before Ph+/BCR-ABL+ status was known) have been enrolled in the study from September 2006 to March 2012. Patients have received a median of 6 cycles (range 1-8) of induction/consolidation. Median age is 55 years (range 21 – 80); 46 patients were older than 50 years, Median WBC at diagnosis was 12 x 109/L (range, 0.4 - 658.1 x 109/L). Ten patients had CNS involvement at presentation. All patients are evaluable for assessment of response to induction; 69 (96%) achieved CR after first cycle or were CR at start. 3 patients died before response assessment from infections. 57 of 69 (83%) evaluable patients achieved cytogenetic (CG) CR after 1 cycle; 5 had a major CG response (4 had 5% and one had 15% Ph+), 2 had insufficient metaphases, and 5 are unknown (no CG exam on day 21 marrow). To date, 45 patients (65%) have achieved complete molecular remission (CMR) and another 19 (28%) have achieved a major (but not complete) molecular response (MMR) at a median of 4 weeks from initiation of treatment (range, 2 – 38 weeks). Minimal residual disease assessment by flow cytometry is negative in 65 (94 %) patients at a median of 3 weeks (range, 2-37 weeks). The median time to neutrophil and platelet recovery for cycle 1 is 18 and 22 days and for subsequent cycles is 15 and 20 days. Grade 3 and 4 adverse events have included bleeding (GI, GU, soft tissue and subdural hematomas), pleural effusions, pericardial effusions, reversible rise in creatinine, deep vein thromboses, pulmonary emboli, as well as diarrhea, infections, hypophosphatemia, hypokalemia, hypocalcemia, hyperglycemia, and elevated transaminases. With a median follow up of 48 months in the surviving patients (range 16.5 - 81.5), 36 patients (50%) are alive and 31 (43%) are in CR. Twelve patients have undergone an allogeneic stem cell transplant. Thirty six patients have died [3 at induction, 16 after relapse, 7 post stem cell transplant performed in CR1, and 10 in CR (6 from infections, 1 from unrelated cardiac event, 1 from unrelated cancer, and 2 from an unknown cause)]. The median disease free survival is 31 months (range, 0.3 to 81) and the median overall survival is 44 months (range, 0.2 to 82). Twenty-one patients have relapsed with a median response duration of 16 months (range, 5 - 62) and 16 of them have died. In 6 patients morphological relapse was preceded by flow and molecular relapse. Six relapsed patients had ABL mutations (4 T315I, 1 F359V, and 1 V299L).

Abstract Background: Although current antiretroviral therapies have effectively changed the course of HIV-1 infection, it remains an incurable illness. The C-C chemokine receptor type 5 (CCR5) is the key co-receptor for HIV entry into CD4+ T cells. Homozygous 32 deletion (delta32) in CCR5 genes leads to resistance to HIV-1 infection 1. Allogeneic stem cell transplant from a donor with CCR5 delta32/32 mutation was curative for HIV in an HIV-1-infected man (Berlin Patient) with AML 2. It has been challenging to replicate this experience. We present our experience with a single case of successful engraftment of CD34-selected, related haploidentical peripheral blood and CCR5delta32 cord blood stem cell transplant (haplo-cord) in an HIV-1-infected woman who, like the Berlin patient, developed AML and is now doing well at almost one-year post transplantation. Clinical case: A 60-year-old African-American woman was diagnosed with HIV-1- infection in June 2013 and was started on an antiretroviral treatment (ART) regimen consisting of tenofovir, emtricitabine and raltegravir. Her pre-ART viral load and CD4 counts were 1,000,000 copies/ml and 1003 cells/mm3, respectively. In Nov, 2013 she had viral load < 20 copies/ml with CD4 counts of 980 cells/mm3 and her HIV-1 infection was relatively asymptomatic. In March 2017, she was diagnosed with AML with monosomy 7. Her HIV therapy after the AML diagnosis was changed to abacavir- lamivudine -dolutegravir- combination. She achieved morphologic and cytogenetic remission after 1 cycle of standard idarubicin/cytarabine induction chemotherapy. In addition, she received 1 cycle of HiDAC consolidation and was referred for allogeneic stem cell transplant. We identified a CCR5 delta32/32 mutated cord blood unit (CBU) which was 5/8 HLA matched and contained 1.3 x 107 nucleated cells/kg and 3.2 x 104 CD34+ cells/kg. She underwent a combined CD34-selected, haploidentical peripheral blood and CCR5delta32 cord blood stem cell transplant (haplo-cord) in August 2017. Her conditioning regimen was with fludarabine/melphalan/and TBI400 and she also received ATG/MMF/tacrolimus for GVHD prophylaxis. Her neutrophils and platelets engrafted on day 10 and 16, respectively and she was discharged on day +16 post-transplant. Her post-discharge hospital course was complicated by CMV reactivation (no organ involvement) 2 months post-transplant with peak viral level of 1374 copies/ml. She did not have evidence for EBV re-activation or graft-vs-host disease. Her plasma HIV viral load remained undetectable post- transplant while remaining on abacavir/lamivudine and dolutegravir-based ART. Her day+180 bone marrow showed continued AML remission and she remains in clinical remission near one year post-transplant. CD3 chimerism showed 82% haploidentical donor and 8% CBU and 10% recipient on day +15 post-transplant (Figure 1). The chimerism composition switched to 96% CBU by day+34, and became and remained 100% CBU since day+55. CD33 chimerism showed 98% haploidentical donor and 2% cord donor on day+15 post-transplant. It was 81% haploidentical donor and 19% cord on day+55 and became 100% cord by day+100. She has continued CD4, CD8, NK and CD19 cell recovery, with normal T cell subsets currently (Figure 2). Her CD4 count dropped to 27 cells/mm3 at one-month post-transplant and currently is at 673cells/mm3. She is currently 11 months post-transplant and is back to her normal daily activities Conclusion: Haplo-cord transplantation with CCR5 delta 32/32 CBU resulted in rapid engraftment and immune replacement with dominance of the CCR5 delta 32/32 CBU graft in an HIV-1-infected woman. Successful suppression of HIV-1-replication to clinically undetectable levels was maintained throughout the transplant period for up to one year. . Correlative viral and immunological studies are ongoing, along with effects on the latent reservoir, which was detectable pre-transplant. It is possible to identify appropriate CCR5 delta 32/32 CBU units for haplo-cord transplantation in HIV-1- infected patients with implications for HIV-1 cure. Figure. Figure.

Mixed Phenotype

T/myeloid mixed-phenotype acute leukemia not otherwise specified (MPAL NOS) is an uncommon and aggressive leukemia without well-established treatment guidelines, particularly when relapsed. Venetoclax plus a hypomethylating agent offers a promising option in this situation since studies support its use in both acute myeloid and, albeit with fewer data to date, acute T-cell-lymphoblastic leukemias. We report the successful eradication of T/myeloid MPAL NOS relapsed after allogeneic stem cell transplant with venetoclax plus decitabine. A consolidative allogeneic stem cell transplant from a second donor was subsequently performed, and the patient remained without evidence of disease more than one year later. Further investigation is indicated to evaluate venetoclax combined with hypomethylating agents and/or other therapies for the management of T/myeloid MPAL NOS.
