Abstract
For cord blood transplantation (CBT), appropriate patient and conditioning regimen selection is necessary to achieve long-term disease-free survival. This review aims to provide comprehensive guidelines on these issues using evidence from the literature and experience at dedicated CBT centers. Topics include patient and disease characteristics that make CBT a good or poor choice and a review of outcomes in commonly used conditioning regimens in CBT. This is accompanied with recommendations on regimen intensity based on disease, organ function, and patient performance status and age. In addition, the use of antithymocyte globulin in CBT is discussed, as is the choice of conditioning in aplastic anemia patients who have access to acceptable CB units.

Abstract
OBJECTIVE/BACKGROUND Cytomegalovirus (CMV) reactivation remains a serious complication after allogeneic hematopoietic cell transplantation (HCT) occurring in approximately 60-70% of CMV-seropositive HCT recipients. CMV reactivation leads to adverse outcomes including end-organ damage, graft-versus-host disease, and graft failure. METHODS Ganciclovir was administered pretransplant at 5 mg/kg twice daily intravenously from the start of conditioning to Day T-2 to CMV-seropositive patients receiving their first allogeneic HCT. CMV DNA was monitored weekly until at least Day 100 posttransplant. RESULTS A total of 109 consecutive patients were treated, median age 57 (range 20-73) years. Of these, 36 (33%) patients had a CMV reactivation within the first 105 days posttransplant with a median time of reactivation of 52.5 (range 36-104) days posttransplant. The cumulative incidence of CMV reactivation at Day 105 posttransplant was 33.1% (95% confidence interval: 24.4-42.0). One patient developed CMV disease. CONCLUSION The use of pretransplant ganciclovir was associated with low incidence of CMV reactivation and disease. These data suggest that pretransplant ganciclovir with preemptive therapy for viral reactivation may be a useful strategy to reduce CMV reactivation. Future prospective trials are needed to compare strategies for CMV prophylaxis.

Abstract
Background Acute myeloid leukemia, the most common acute leukemia in adults, has a poor overall survival. Studies have suggested that certain socioeconomic factors such as living in a rural or farming area are associated with worse outcomes. Since 42% of acute myeloid leukemia patients seen in our academic center reside in a rural area, we have a unique opportunity to study outcomes of patients in rural versus urban settings. Aim This analysis evaluates the effect of geography and socioeconomic factors on the biology, treatment, and overall survival of patients with acute myeloid leukemia, with the goal of understanding health care disparities. Methods and results Patient characteristics, cytogenetic data, treatment history, and overall survival were collected and analyzed to identify differences between urban and rural residency. This cohort included 42% of patients who resided in a rural area at the time of acute myeloid leukemia diagnosis. There was no difference in overall survival between the cohorts. The 1 year overall survival for the entire cohort was 47.9%. There was no difference detected in rates of adverse cytogenetics between the rural and urban cohorts. Similar numbers of patients received induction chemotherapy or proceeded to allogeneic stem cell transplant between the cohorts. Conclusions This study highlights that similar outcomes can be achieved in rural and urban patients, suggesting that intensive efforts at telehealth, education, and collaboration with local oncology practices may be beneficial.

Abstract
PURPOSE OF REVIEW Rearrangements of the histone lysine [K]-MethylTransferase 2A gene (KMT2A) gene on chromosome 11q23, formerly known as the mixed-lineage leukemia (MLL) gene, are found in 10% and 5% of adult and children ALL cases, respectively. The most common translocated genes are AFF1 (formerly AF4), MLLT3 (formerly AF9), and MLLT1 (formerly ENL). The bimodal incidence of MLL-r-ALL usually peaks in infants in their first 2 years of life and then declines thereafter during the pediatric/young adult phase until it increases again with age. MLL-rearranged ALL (MLL-r-ALL) is characterized by hyperleukocytosis, aggressive behavior with early relapse, relatively high incidence of central nervous system (CNS) involvement, and poor prognosis. RECENT FINDINGS MLL-r-ALL cells are characterized by relative resistance to corticosteroids (due to Src kinase-induced phosphorylation of annexin A2) and L-asparaginase therapy, but they are sensitive to cytarabine chemotherapy (due to increased levels of hENT1 expression). Potential therapeutic targets include FLT3 inhibitors, MEK inhibitors, HDAC inhibitors, BCL-2 inhibitors, MCL-1 inhibitors, proteasome inhibitors, hypomethylating agents, Dot1L inhibitors, and CDK inhibitors. In this review, we discuss MLL-r-ALL focusing on clinical presentation, risk stratification, drug resistance, and treatment strategies, including potential novel therapeutic targets.

Abstract
Establishing a hematopoietic cell transplantation (HCT) program is complex. Planning is essential while establishing such a program to overcome the expected challenges. Authorities involved in HCT program establishment will need to coordinate the efforts between the different departments required to start up the program. One essential department is pharmacy and the medications required. To help facilitate this, the Worldwide Network for Blood and Marrow Transplantation organized a structured survey to address the essential medications required to start up an HCT program. A group of senior physicians and pharmacists prepared a list of the medications used at the different phases of transplantation. These drugs were then rated by a questionnaire using a scale of necessity based on the stage of development of the transplant program. The questionnaire was sent to 30 physicians, in different parts of the world, who have between 5 and 40 years of experience in autologous and/or allogeneic transplantation. This group of experts scored each medication on a 7-point scale, ranging from an absolute requirement (score of 1) to not required (score of 7). The results are presented here to help guide the prioritization of required medications.

Abstract
Unfortunately, many patients referred for hematopoietic cell transplant will not have a fully matched related donor, and finding matched unrelated donors through the registry may be difficult, especially if the recipient is not of Northern European descent [N Engl J Med 2014;371:339‐348]. Umbilical cord blood (UCB) has been an available graft source for hematopoietic cell transplant for more than 30 years, since the first UCB transplant was performed in the late 1980s [N Engl J Med 1989;321:1174‐1178]. UCB is readily available, has low immunogenicity, and does not require as strict of human leukocyte antigen (HLA) matching compared to other graft sources [N Engl J Med 2004;351:2265‐2275]. According to data from the Center for International Blood and Marrow Transplant Research (CIBMTR), an estimated 500 patients in the US will have received a UCB transplant in 2018. Since 2014, haploidentical transplants have surpassed UCB transplants performed in the United States (CIBMTR Summary Slides, 2018, available at https://www.cibmtr.org). Increased use of haploidentical transplants has brought to light concerns about UCB transplants, including delayed engraftment and graft failure, increased nonrelapse mortality, increased infection risk, and UCB acquisition costs [Lancet Oncol 2010;11:653‐660; Biol Blood Marrow Transplant 2019;1456‐1464]. These concerns will need to be addressed for UCB to remain a viable option as a graft source for hematopoietic cell transplant. Other promising therapeutic benefits for UCB, in addition to hematopoietic cell transplant, is its use in regenerative medicine and immune modulation, which is currently being evaluated in ongoing clinical trials.

Abstract
BACKGROUND Increased aurora A kinase (AAK) expression occurs in acute myeloid leukaemia; AAK inhibition is a promising therapeutic target in this disease. We therefore aimed to assess the activity of alisertib combined with 7 + 3 induction chemotherapy in previously untreated patients with high-risk acute myeloid leukaemia. METHODS We did a single-arm, phase 2 trial of patients recruited from the Dana-Farber/Harvard Cancer Center in the USA. Eligible patients had previously untreated acute myeloid leukaemia, an Eastern Cooperative Oncology Group performance status of 0-2, and were at high risk of disease as defined by the presence of an adverse-risk karyotype, the presence of secondary acute myeloid leukaemia arising from previous myelodysplastic syndrome or myeloproliferative neoplasm, the presence of therapy-related acute myeloid leukaemia, or being 65 years or older. Enrolled patients received 7 + 3 induction chemotherapy of continuous infusion of cytarabine (100 mg/m2 per day on days 1-7) and intravenous bolus of idarubicin (12 mg/m2 per day on days 1-3). Oral alisertib (30 mg) was given twice per day on days 8-15. Patients could receive up to four consolidation cycles with cytarabine and alisertib, and alisertib maintenance for 12 months. The primary endpoint was a composite including the proportion of patients achieving complete remission and those with a complete remission with incomplete neutrophil or platelet count recovery. Analyses were per-protocol. This study is registered with Clinicaltrials.gov, number NCT02560025, and has completed enrolment. FINDINGS Between Dec 31, 2015, and Aug 1, 2017, we enrolled a total of 39 eligible patients. 19 (49%) of 39 patients had secondary acute myeloid leukaemia and three (8%) had therapy-related acute myeloid leukaemia. At mid-induction, 33 (85%) of 39 patients showed marrow aplasia, six (15%) received re-induction. The median follow-up was 13·7 months (IQR 12·7-14·4). Composite remission was 64% (two-stage 95% CI 48-79), with 20 (51%) of 39 patients achieving complete remission and five (13%) achieving complete remission with incomplete neutrophil or platelet count recovery. The most common grade 3 or 4 adverse events included febrile neutropenia (16 [41%] of 39), neutropenia (12 [31%]), thrombocytopenia (13 [33%]), anaemia (11 [28%]), anorexia (nine [23%]), and oral mucositis (four [10%]). No treatment-related deaths were observed. INTERPRETATION These results suggest that alisertib combined with induction chemotherapy is active and safe in previously untreated patients with high-risk acute myeloid leukaemia. This study met criteria to move forward to a future randomised trial. FUNDING Millennium Pharmaceuticals.

Abstract
Aggressive curative therapies have now been extended to patients older than 65 years, a fast-growing segment of the population. As the number of allogeneic transplants in patients older than age 65 is increasing, attention is now focused on improving outcomes in this group. This paper discusses important aspects of allogeneic transplant in the older patient, focusing on donor and patient selection, choice of conditioning regimen and graft source, and the importance of timely access to a transplant center.

Abstract
Since Jehovah's Witness (JW) patients diagnosed with leukaemia refuse blood transfusions, they are often denied intensive chemotherapy for fear they could not survive myeloablation without blood transfusion support. Treatment of JW patients with acute leukaemia is challenging and carries a higher morbidity and mortality; however, the refusal of blood products should not be an absolute contraindication to offer multiple treatment modalities including haematopoietic stem cell transplantation. In this review we discuss their optimal management and describe alternative modalities to blood transfusions to provide sufficient oxygenation and prevent bleeding.

Abstract
Health care costs attributed to biologics have increased exponentially in the recent years, thus biosimilars offer a possible solution to limit costs while maintaining safety and efficacy. Reducing expenditure is vital to health care especially in developing countries where affordability and access to health care is a major challenge. We discuss the opportunities and the challenges of biosimilars in the field of hematopoietic cell transplantation (HCT) in low- and lower-middle income countries. Developing countries can potentially invest in the forecasted costs reduction by utilizing biosimilars. This can be used to decrease the costs of procedures such as HCT, which is a rapidly growing field in many developing regions. The introduction of biosimilars in the developing regions faces many challenges which include, but are not limited to: legal and regulatory issues, lack of research infrastructure, and the presence of educational barriers. Thus, collaborative efforts are needed to ensure an effective and safe introduction of biosimilars into low- and lower-middle income countries.

Abstract
4135 Background: Conventional chemotherapy (chemo) for locally advanced pancreatic cancer (LAPC) and metastatic pancreatic cancer (MPC) has dismal responses and poor survival rates. Arming activated T cells (ATC) with anti-CD3 x anti-EGFR bispecific antibody (BATs) makes every ATC into an EGFR-specific cytotoxic T cell that secretes cytokines, proliferates, and kills tumor. Methods: We report on 5 phase I (P1) and 15 phase II (P2) patients. In our phase I study, BATs were used to treat LAPC or MPC patients at Karmanos Cancer Institute (NCT0140874) in a dose escalation involving 3 weekly infusions of 1, 2, and 4 x 1010 BATs/infusion, followed by a booster infusion at 3 months (mos) for a total of up to 8 x 1010 BATs. No dose limiting toxicities were observed in the outpatient infusions. Fifteen patients treated on a phase II (NCT02620865) at KCI and (NCT03269526) at University of Virginia received biweekly infusions of 1010 BATs/infusion over 4 weeks for a total of 8 x 1010 EGFR BATs. Results: Four patients had stable disease (SD) for 6.1, 6.5, 5.3, and 36 mos. Two patients had complete responses (CR) when chemo was restarted after BATs. The median overall survival (OS) for 17 evaluable patients (3 of 4 infusions in the P1 and all 8 infusions in the P2) was 31 mos, and the median OS for all 20 patients (3 in the P2 who did not complete 8 infusions) is 14.5 mos (95% CI, 7.5-45.2 mos). Patient IT20104 had an apparent “pseudoprogression” after 3 BATs infusions, but achieved a CR after restarting capcitabine and is alive off therapy at 54 mos (24 mos after stopping capecitabine). Immune evaluations on the P1 patients show specific cytotoxicity to MiaPaCa-2 by peripheral blood mononuclear cells (PBMC) increased from 21% to 31% 2 weeks after the 3rd infusion, and IFN-γ EliSpots increased from < 20 to 1000 IFN-γ EliSpots/106 PBMC (p < 0.03). Patient IT 20121 (SD for 36 mos) increased IFN-γ EliSpots from 250 to 3200/106 PBMC after 8 infusions. Innate cytotoxicity responses in the P1 patients increased significantly after infusions (p < 0.04). Levels of IP-10 increased significantly (p < 0.04), and levels of IL-8 decreased but not significantly (p < 0.07). Conclusions: Infusions of BATs are safe and induce endogenous adaptive anti-tumor responses. Targeting PC with BATs may stabilize disease, leading to improved OS, as well as evidence that BATs infusions can induce anti-tumor activity and immunosensitize tumors to subsequent chemo.
