Abstract
BACKGROUND AIMS Cell therapies are an emerging treatment option for a variety of diseases, especially with the success of chimeric antigen receptor T-cell therapies. With 18 FDA-approved cell therapy products as of December 2020 and a growing number in clinical trials, standards for most aspects of the cell therapy lifecycle are well-established by professional organizations like AABB and FACT; however, there are limited standardized protocols regarding the day-of infusion. METHODS Infusions were observed at three academic medical centers in the United States, and the workflows were analyzed and compared based on factors including facility layout, product verification processes, cryobag design, timing restrictions, and use of electronic medical records. RESULTS Variations between the facilities were identified with product thawing location and cell therapy lab location being the most important factors in time from thaw to infusion. CONCLUSIONS Based on this analysis, opportunities were identified for standardization and streamlining the infusion workflow which may help facilitate adoption of new and existing cell therapies at a wider range of hospitals.

Abstract
Administration of posttransplant cyclophosphamide (PTCy) has significantly expanded the number of patients undergoing HLA-haploidentical hematopoietic cell transplantation (haplo-HCT). To examine immune reconstitution in these patients, we monitored T- and natural killer (NK)-cell recovery in 60 patients receiving bone marrow or peripheral blood stem cell (PBSC) grafts after haplo-HCT with PTCy and 35 patients receiving HLA-matched donor PBSC grafts with standard graft-versus-host disease (GVHD) prophylaxis. Compared with HLA-matched recipients, early T-cell recovery was delayed in haplo-HCT patients and skewed toward effector memory T cells with markedly reduced naive T cells. We found higher regulatory T (Treg)-cell/conventional T (Tcon)-cell ratios early after HCT and increased PD-1 expression on memory T cells. Within the haplo-HCT, patients who did not develop chronic GVHD (cGVHD) had higher PD-1 expression on central and effector memory CD4+ Treg cells at 1 month after transplant. These findings suggest an immunologic milieu that promotes immune tolerance in haplo-HCT patients. NK cells were decreased early after haplo-HCT with preferential expansion of immature CD56brightCD16- NK cells compared with matched donor transplants. One month after transplant, mass cytometry revealed enrichment of immature NK-cell metaclusters with high NKG2A, low CD57, and low killer-cell immunoglobulin-like receptor expression after haplo-HCT, which partially recovered 3 months post-HCT. At 2 months, immature NK cells from both groups were functionally impaired, but interleukin-15 priming corrected these defects in vitro. Increased immature/mature NK-cell ratios were associated with cytomegalovirus reactivation and increased incidence of cGVHD after haplo-HCT. These homeostatic imbalances in T- and NK-cell reconstitution after haplo-HCT reveal opportunities for early immune-based interventions to optimize clinical outcomes.

Abstract
BACKGROUND Sickle cell disease is characterized by hemolytic anemia, pain, and progressive organ damage. A high level of erythrocyte fetal hemoglobin (HbF) comprising α- and γ-globins may ameliorate these manifestations by mitigating sickle hemoglobin polymerization and erythrocyte sickling. BCL11A is a repressor of γ-globin expression and HbF production in adult erythrocytes. Its down-regulation is a promising therapeutic strategy for induction of HbF. METHODS We enrolled patients with sickle cell disease in a single-center, open-label pilot study. The investigational therapy involved infusion of autologous CD34+ cells transduced with the BCH-BB694 lentiviral vector, which encodes a short hairpin RNA (shRNA) targeting BCL11A mRNA embedded in a microRNA (shmiR), allowing erythroid lineage-specific knockdown. Patients were assessed for primary end points of engraftment and safety and for hematologic and clinical responses to treatment. RESULTS As of October 2020, six patients had been followed for at least 6 months after receiving BCH-BB694 gene therapy; median follow-up was 18 months (range, 7 to 29). All patients had engraftment, and adverse events were consistent with effects of the preparative chemotherapy. All the patients who could be fully evaluated achieved robust and stable HbF induction (percentage HbF/(F+S) at most recent follow-up, 20.4 to 41.3%), with HbF broadly distributed in red cells (F-cells 58.9 to 93.6% of untransfused red cells) and HbF per F-cell of 9.0 to 18.6 pg per cell. Clinical manifestations of sickle cell disease were reduced or absent during the follow-up period. CONCLUSIONS This study validates BCL11A inhibition as an effective target for HbF induction and provides preliminary evidence that shmiR-based gene knockdown offers a favorable risk-benefit profile in sickle cell disease.

Abstract
BACKGROUND The efficacy of interleukin-6 receptor blockade in hospitalized patients with coronavirus disease 2019 (Covid-19) who are not receiving mechanical ventilation is unclear. METHODS We performed a randomized, double-blind, placebo-controlled trial involving patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, hyperinflammatory states, and at least two of the following signs: fever (body temperature >38°C), pulmonary infiltrates, or the need for supplemental oxygen in order to maintain an oxygen saturation greater than 92%. Patients were randomly assigned in a 2:1 ratio to receive standard care plus a single dose of either tocilizumab (8 mg per kilogram of body weight) or placebo. The primary outcome was intubation or death, assessed in a time-to-event analysis. The secondary efficacy outcomes were clinical worsening and discontinuation of supplemental oxygen among patients who had been receiving it at baseline, both assessed in time-to-event analyses. RESULTS We enrolled 243 patients; 141 (58%) were men, and 102 (42%) were women. The median age was 59.8 years (range, 21.7 to 85.4), and 45% of the patients were Hispanic or Latino. The hazard ratio for intubation or death in the tocilizumab group as compared with the placebo group was 0.83 (95% confidence interval [CI], 0.38 to 1.81; P = 0.64), and the hazard ratio for disease worsening was 1.11 (95% CI, 0.59 to 2.10; P = 0.73). At 14 days, 18.0% of the patients in the tocilizumab group and 14.9% of the patients in the placebo group had had worsening of disease. The median time to discontinuation of supplemental oxygen was 5.0 days (95% CI, 3.8 to 7.6) in the tocilizumab group and 4.9 days (95% CI, 3.8 to 7.8) in the placebo group (P = 0.69). At 14 days, 24.6% of the patients in the tocilizumab group and 21.2% of the patients in the placebo group were still receiving supplemental oxygen. Patients who received tocilizumab had fewer serious infections than patients who received placebo. CONCLUSIONS Tocilizumab was not effective for preventing intubation or death in moderately ill hospitalized patients with Covid-19. Some benefit or harm cannot be ruled out, however, because the confidence intervals for efficacy comparisons were wide. (Funded by Genentech; ClinicalTrials.gov number, NCT04356937.).

Abstract
Tisagenlecleucel is a CD19 chimeric antigen receptor (CAR) T-cell therapy approved for treatment of pediatric and young adult patients with relapsed/refractory acute lymphoblastic leukemia (ALL) and adults with non-Hodgkin lymphoma (NHL). The initial experience with tisagenlecleucel in a real-world setting from a cellular therapy registry is presented here. As of January 2020, 511 patients were enrolled from 73 centers, and 410 patients had follow-up data reported (ALL, n = 255; NHL, n = 155), with a median follow-up of 13.4 and 11.9 months for ALL and NHL, respectively. Among patients with ALL, the initial complete remission (CR) rate was 85.5%. Twelve-month duration of response (DOR), event-free survival, and overall survival (OS) rates were 60.9%, 52.4%, and 77.2%, respectively. Among adults with NHL, the best overall response rate was 61.8%, including an initial CR rate of 39.5%. Six-month DOR, progression-free survival, and OS rates were 55.3%, 38.7%, and 70.7%, respectively. Grade ≥3 cytokine release syndrome and neurotoxicity were reported in 11.6% and 7.5% of all patients, respectively. Similar outcomes were observed in patients with in-specification and out-of-specification products as a result of viability <80% (range, 61% to 79%). This first report of tisagenlecleucel in the real-world setting demonstrates outcomes with similar efficacy and improved safety compared with those seen in the pivotal trials.

Abstract
Abstract
Purpose
Cardiovascular complications of chimeric antigen receptor T-cell (CAR T-cell) therapy are poorly understood. We examined the incidence, predictors and impact of new or worsening cardiomyopathy in patients undergoing CAR T-cell therapy.
Methods
All patients with refractory or relapsed non-Hodgkin's lymphoma, undergoing CAR T-cell therapy at collaborative institutes underwent serial echocardiograms at baseline and within 7 days after developing high-grade cytokine release syndrome (CRS), and were followed for all-cause mortality. New or worsening cardiomyopathy was defined as a reduction in left ventricular ejection fraction (LVEF) >10% from baseline to <50% during the index hospitalization.
Results
Among 187 consecutive CAR T-cell therapy patients, 116 (50 Grade ≤1 CRS, 66 Grade ≥2 CRS) had >1 echocardiogram performed and were included in this analysis. The median age was 63 (range 19–80) years, 42% were women, 91% were Caucasian. A total of 12 (10.3%) patients developed new or worsening cardiomyopathy with a decline in LVEF from 58±6% to 36±7% within a median of 12.5 (range 2–24) days of CAR T-cell infusion. In multivariable analyses, older age, prior stem cell transplantation, baseline angiotensin-converting enzyme inhibitor use and CRS grade ≥2 were associated with the development of cardiomyopathy. Patients who developed cardiomyopathy were more likely to require vasopressor support (p=0.004) and mechanical ventilation (p=0.014). LVEF improved in 9/12 (75%) patients. CAR T-cell associated cardiomyopathy did not impact overall mortality or cancer response to CAR-T cell therapy.
Conclusions
Patients undergoing CAR T-cell therapy are at risk of developing cardiomyopathy and hemodynamic instability. Pre-CAR T-cell therapy cardiovascular risk stratification and echocardiogram surveillance during therapy should be considered for prompt identification and mitigation of cardiac complications.

Abstract
PURPOSE Axicabtagene ciloleucel (axi-cel) was approved by the Food and Drug Administration for relapsed aggressive B-cell non-Hodgkin lymphoma in part on the basis of durable remission rates of approximately 40% in a clinical trial population. Whether this efficacy, and the rates of toxicity, would be consistent in a postcommercial setting, with relaxed eligibility criteria and bridging therapy, is unknown. This study describes the efficacy and safety correlates and outcomes in this setting. PATIENTS AND METHODS One hundred twenty-two patients from 7 medical centers in the United States were treated with axi-cel and were included in a modified intent-to-treat (mITT) analysis. Seventy-six patients (62%) were ineligible for the ZUMA-1 trial. Response and toxicity rates, duration of response (DOR), survival, and covariates are described on the basis of the mITT population. Correlative studies on blood and tumor samples were performed to investigate potential biomarkers of response and resistance. RESULTS Median follow-up was 10.4 months. In the mITT population, the best overall and complete response (CR) rates were 70% and 50%, respectively. Median DOR and progression-free survival (PFS) were 11.0 and 4.5 months in all patients and were not reached (NR) in CR patients. Median overall survival (OS) was NR; 1-year OS was 67% (95% CI, 59% to 77%). Although response rates were similar in the ZUMA-1-eligible and ZUMA-1-ineligible groups (70% v 68%), there was a statistically significant improvement in CR rate (63% v 42%, P = .016), DOR (median, NR v 5.0 months; P = .014), PFS (median, NR v 3.3 months; P = .020), and OS (1-year OS, 89% v 54%; P < .001) in patients who were ZUMA-1 eligible. Rates of grade ≥ 3 cytokine release syndrome and neurotoxicty were 16% and 35%, respectively. CONCLUSION Axi-cel yields similar rates of overall response and toxicity in commercial and trial settings, although CR rates and DOR were more favorable in patients eligible for ZUMA-1.

Abstract
Delayed reconstitution of the immune system is a long-recognized complication after allogeneic hematopoietic cell transplantation (HCT). Specifically, loss of T cell diversity has been thought to contribute to infectious complications, graft-versus-host disease (GVHD), and disease relapse. We performed serial high-resolution next-generation sequencing of T cell receptor (TCR)-β in 99 related or unrelated donor (57 unrelated, 42 related) allogeneic HCT recipients (55 with reduced-intensity conditioning, 44 with myeloablative conditioning) during the first 3 months after HCT using the immunoSEQ Assay. We measured T cell fraction, clonality (1- Peilou's evenness) and Daley-Smith richness from recipient samples at multiple time points. In agreement with previous studies, we found that although absolute T cell numbers recover relatively quickly after HCT, T cell repertoire diversity remains diminished. Restricted diversity was associated with conditioning intensity, use of antithymocyte globulin, and donor type. Increased number of expanded clones compared to donor T cell clones at day +30 was associated with the incidence of acute GVHD (hazard ratio [HR], 1.11; P = .00005). Even after exclusion of the 12 patients who developed acute GVHD before day +30, the association between acute GVHD and increased clonal expansion at day +30 remained (HR, 1.098; P = .041), indicating that increased clonal T cell expansion preceded the development of acute GVHD. Our results highlight T cell clonal expansion as a potential novel biomarker for acute GVHD that warrants further study.

Abstract
A major cause of morbidity and mortality for patients who undergo hematologic stem cell transplantation (HSCT) is acute graft-versus-host disease (aGVHD), a mostly T cell-mediated disease. Examination of the T cell receptor (TCR) repertoire of HSCT recipients and the use of next-generation nucleotide sequencing have raised the question of whether features of TCR repertoire reconstitution might reproducibly associate with aGVHD. We hypothesized that the peripheral blood TCR repertoire of patients with steroid-nonresponsive aGVHD would be less diverse. We also hypothesized that patients with GVHD who shared HLA might also share common clones at the time of GVHD diagnosis, thereby potentially providing potential clinical indicators for treatment stratification. We further hypothesized that HSCT recipients with the same HLA mismatch might share a more similar TCR repertoire based on a potentially shared focus of alloreactive responses. We studied 2 separate patient cohorts and 2 separate platforms for measuring TCR repertoire. The first cohort of patients was from a multicenter Phase III randomized double-blinded clinical trial of patients who developed aGVHD (NCT01002742). The second cohort comprised samples from biobanks from 2 transplantation centers and the Center for International Blood and Marrow Transplant Research of patients who underwent mismatched HSCT. There were no statistically significant differences in the TCR diversity of steroid responders and nonresponders among patients with aGVHD on the day of diagnosis. Most clones in the repertoire were unique to each patient, but a small number of clones were found to be both exclusive to and shared among aGVHD nonresponders. We were also able to show a strong correlation between the presence of Vβ20 and Vβ29 and steroid responsiveness. Using the Bhattacharya coefficient, those patients who shared the same HLA mismatch were shown to be no more similar to one another than to those who had a completely different mismatch. Using 2 separate clinical cohorts and 2 separate platforms for analyzing the TCR repertoire, we have shown that the sampled human TCR repertoire is largely unique to each patient but contains glimmers of common clones of subsets of clones based on responsiveness to steroids in aGVHD on the day of diagnosis. These studies are informative for future strategies to assess for reproducible TCR responses in human alloreactivity and possible markers of GVHD responsiveness to therapy.

Abstract
Chimeric antigen receptor (CAR) T cells are a new and powerful class of cancer immunotherapeutics that have shown potential for the treatment of hematopoietic malignancies. The tremendous promise of this approach is tempered by safety concerns, including potentially fatal neurotoxicity, sometimes but not universally associated with cytokine release syndrome. We describe the postmortem examination of a brain from a 21-year-old patient with relapsed pre-B cell acute lymphoblastic leukemia (ALL) who died from fulminant cerebral edema following CAR T-cell infusion. We found a range of changes that included activation of microglia, expansion of perivascular spaces by proteinaceous exudate, and clasmatodendrosis-a beading of glial fibrillary acidic protein consistent with astrocyte injury. Notably, within the brain parenchyma, we identified only infrequent T cells and did not identify ALL cells or CAR T cells. The overall findings are nonspecific but raise the possibility of astrocyte and blood-brain barrier dysfunction as a potential etiology of fatal CAR T-cell neurotoxicity in this patient.

Abstract
NKG2D ligands are widely expressed in solid and hematologic malignancies but absent or poorly expressed on healthy tissues. We conducted a phase I dose-escalation study to evaluate the safety and feasibility of a single infusion of NKG2D-chimeric antigen receptor (CAR) T cells, without lymphodepleting conditioning in subjects with acute myeloid leukemia/myelodysplastic syndrome or relapsed/refractory multiple myeloma. Autologous T cells were transfected with a γ-retroviral vector encoding a CAR fusing human NKG2D with the CD3ζ signaling domain. Four dose levels (1 × 106-3 × 107 total viable T cells) were evaluated. Twelve subjects were infused [7 acute myeloid leukemia (AML) and 5 multiple myeloma]. NKG2D-CAR products demonstrated a median 75% vector-driven NKG2D expression on CD3+ T cells. No dose-limiting toxicities, cytokine release syndrome, or CAR T cell-related neurotoxicity was observed. No significant autoimmune reactions were noted, and none of the ≥ grade 3 adverse events were attributable to NKG2D-CAR T cells. At the single injection of low cell doses used in this trial, no objective tumor responses were observed. However, hematologic parameters transiently improved in one subject with AML at the highest dose, and cases of disease stability without further therapy or on subsequent treatments were noted. At 24 hours, the cytokine RANTES increased a median of 1.9-fold among all subjects and 5.8-fold among six AML patients. Consistent with preclinical studies, NKG2D-CAR T cell-expansion and persistence were limited. Manufactured NKG2D-CAR T cells exhibited functional activity against autologous tumor cells in vitro, but modifications to enhance CAR T-cell expansion and target density may be needed to boost clinical activity.

Abstract
BACKGROUND Immune checkpoint inhibitor therapy is a modern breakthrough in medical oncology, but it can precipitate inflammatory and autoimmune adverse effects. Among the most serious of these toxicities is haemophagocytic lymphohistiocytosis (HLH), a life-threatening disorder of unbridled immune activation that results in injury to multiple organ systems. OBJECTIVE Description of a case of pembrolizumab-associated HLH in a patient with a proposed underlying genetic risk factor for its occurrence. METHODS AND RESULTS We describe a patient with aggressive metastatic breast cancer who developed HLH while undergoing experimental treatment with pembrolizumab, resulting in critical illness and multiorgan system failure. Pembrolizumab discontinuation and high-dose corticosteroids were effective in managing HLH. Subsequent next-generation sequencing of 15 genes associated with HLH revealed a germline polymorphism in perforin-1 (PRF1), PRFA91V, that may have predisposed the patient to develop HLH. The patient has had no evidence of malignancy for 2 years following recovery despite receiving no further cancer-directed treatment. CONCLUSIONS HLH is a rare but serious complication of immune checkpoint blockade. Patients with underlying hypomorphic alleles in PRF1 may be predisposed to develop this toxicity. Further studies are necessary to confirm a possible link between perforin gene mutations and immune checkpoint blockade-associated HLH.

Upper gastrointestinal acute graft- versus-host disease adds minimal prognostic value in isolation or with other graft- versus-host disease symptoms as currently diagnosed and treated. Haematologica 2018; 103:1708-1719.

Abstract
Upper gastrointestinal acute graft-versus-host disease is reported in approximately 30% of hematopoietic stem cell transplant recipients developing acute graft-versus-host disease. Currently classified as Grade II in consensus criteria, upper gastrointestinal acute graft-versus-host disease is often treated with systemic immunosuppression. We reviewed the Center for International Blood and Marrow Transplant Research database to assess the prognostic implications of upper gastrointestinal acute graft-versus-host disease in isolation or with other acute graft-versus-host disease manifestations. 8567 adult recipients of myeloablative allogeneic hematopoietic stem cell transplant receiving T-cell replete grafts for acute leukemia, chronic myeloid leukemia or myelodysplastic syndrome between 2000 and 2012 were analyzed. 51% of transplants were from unrelated donors. Reported upper gastrointestinal acute graft-versus-host disease incidence was 12.1%; 2.7% of recipients had isolated upper gastrointestinal acute graft-versus-host disease, of whom 95% received systemic steroids. Patients with isolated upper gastrointestinal involvement had similar survival, disease-free survival, transplant-related mortality, and relapse as patients with Grades 0, I, or II acute graft-versus-host disease. Unrelated donor recipients with isolated upper gastrointestinal acute graft-versus-host disease had less subsequent chronic graft-versus-host disease than those with Grades I or II disease (P=0.016 and P=0.0004, respectively). Upper gastrointestinal involvement added no significant prognostic information when present in addition to other manifestations of Grades I or II acute graft-versus-host disease. If upper gastrointestinal symptoms were reclassified as Grade 0 or I, 425 of 2083 patients (20.4%) with Grade II disease would be downgraded, potentially impacting the interpretation of clinical trial outcomes. Defining upper gastrointestinal acute graft-versus-host disease as a Grade II entity, as it is currently diagnosed and treated, is not strongly supported by this analysis. The general approach to diagnosis, treatment and grading of upper gastrointestinal symptoms and their impact on subsequent acute graft-versus-host disease therapy warrants reevaluation.
