Abstract
Chimeric antigen receptor T cells (CAR-Ts) have remarkable efficacy in liquid tumors, but limited responses in solid tumors. We conducted a Phase I trial (NCT02107963) of GD2 CAR-Ts (GD2-CAR.OX40.28.z.iC9), demonstrating feasibility and safety of administration in children and young adults with osteosarcoma and neuroblastoma. Since CAR-T efficacy requires adequate CAR-T expansion, patients were grouped into good or poor expanders across dose levels. Patient samples were evaluated by multi-dimensional proteomic, transcriptomic, and epigenetic analyses. T cell assessments identified naive T cells in pre-treatment apheresis associated with good expansion, and exhausted T cells in CAR-T products with poor expansion. Myeloid cell assessment identified CXCR3+ monocytes in pre-treatment apheresis associated with good expansion. Longitudinal analysis of post-treatment samples identified increased CXCR3- classical monocytes in all groups as CAR-T numbers waned. Together, our data uncover mediators of CAR-T biology and correlates of expansion that could be utilized to advance immunotherapies for solid tumor patients.

Abstract
Abstract
Background: Chimeric antigen receptor T cells (CARTs) hold promising therapeutic potential for refractory tumors. GD2 is a tumor antigen expressed on neuroblastoma and osteosarcoma. In initial studies, T cells expressing 1st generation GD2-CARTs were shown to be safe and mediated modest antitumor activity in some patients with refractory neuroblastoma.
Methods: We developed a 3rd generation GD2-CART (GD2-CAR.OX40.28.z.ICD9) and conducted a phase I trial (NCT02107963) to determine the feasibility of producing and safety of administering escalating doses of GD2-CARTs in children and young adults with GD2+ solid tumors, including neuroblastoma and osteosarcoma, following cyclophosphamide-based lymphodepletion. Patient samples were evaluated for cytokine profile kinetics, immune phenotype analysis with mass cytometry (CyTOF), transcriptomic evaluation with RNA-sequencing (RNA-seq), epigenetic determination with Assay for Transposase-Accessible Chromatin using sequencing (ATAC-seq), and functional studies with flow cytometry.
Results: 15 patients aged 8-28 years were enrolled on four dose levels, of which 13 patients were infused. No dose-limiting toxicities were observed and administration of up to 1x107 GD2-CART/kg was feasible and safe for children and young adults with neuroblastoma and osteosarcoma. 15.4% (2/13) of patients experienced grade-1 cytokine release syndrome (CRS) and no neurological toxicity was observed. We measured the expansion and persistence of adoptively transferred GD2-CARTs in the peripheral blood. GD2-CARTs expanded in all patients receiving treatment, half of whom had expansion similar to that seen in clinically active CD19 and CD22 CARTs, but the GD2-CARTs had limited persistence. At Day 28 following GD2-CART infusion, 23.1% (3/13) of evaluable patients had progressive disease and 76.9% (10/13) had stable disease (SD). 3/10 SD patients remained stable at 60 days post-GD2-CART, but all patients eventually progressed. Since a major barrier to CART efficacy is inadequate CART expansion, we comprehensively evaluated for phenotypic, transcriptomic, and epigenetic immune profiles of patient apheresis, CART product, and post-treatment peripheral blood samples to identify determinants of CART expansion. GD2-CART expansion is significantly correlated with several T cell markers, and a larger baseline naïve and central memory T cell pool. Unique myeloid populations are associated with CART expansion. ATACseq identifies epigenetic differences in pre-treatment apheresis that may predict good CAR expansion in patients.
Conclusions: GD2-CART therapy following cyclophosphamide conditioning was well tolerated at all four dose levels in pediatric and young adult patients with neuroblastoma and osteosarcoma. Subsequent multi-dimensional analyses suggest key mechanisms underlying CART biology and function and highlight the potential of defining and applying molecular signatures in apheresis and CART product as biomarkers and prognostic indicators of CART expansion, with promise for advancing immunotherapies for solid tumor patients in the future.

Abstract
Abstract
Monocytes are innate immune cells recognized for their ability to play both tumor permissive and surveillant roles in cancer. Circulating classical monocytes (CD14+CD16−) can home to the tumor and suppress other immune cells through various mechanisms, including the production of arginase and the release of reactive oxygen species (ROS). Conversely, patrolling nonclassical monocytes (CD14−CD16+) have been shown to employ processes such as phagocytosis and presentation of tumor antigens to prevent metastasis. This heterogeneous monocyte function is influenced by tumor-derived factors that are released during cancer development and progression. Phenotypic and transcriptional alterations in circulating monocytes and other myeloid cells in patients with solid tumors have been reported and associated with poor clinical outcomes. However, perturbations of specific monocyte functions in the setting of solid tumors have not been well explored. Here we present a characterization of monocytes by coupling flow cytometry-based functional assays with sequencing (Func-seq). Healthy donor primary monocytes and monocytic cell lines were used to examine the production of ROS and arginase in response to osteosarcoma-conditioned media and monocyte-mediated phagocytosis of osteosarcoma cells. Bulk RNA-seq and ATAC-seq were performed on FACS-sorted populations to compare differentially expressed genes and establish transcriptomic and epigenetic signatures associated with monocyte-mediated immunosuppression and tumor-cell phagocytosis. The incorporation of functional selection into -omic characterization provides insights into monocyte behavior and potential therapeutic targets to alter their activity in solid tumors.

Abstract
Abstract
Monocytes are a heterogeneous group of mononuclear innate immune cells that have diverse inflammatory responses. In the context of cancer, monocytes and monocyte-derived cells have been evaluated for their pro- and anti-tumoral effects in the tumor microenvironment. These functions range from induction of tumor cell death to suppression of T cells, promotion of angiogenesis and remodeling of the extracellular matrix. Outside of the primary tumor, monocytes in circulation maintain their dichotomous role in cancer immunosurveillance. Specifically, patrolling non-classical CD14−CD16+ monocytes have been found to play a role in the prevention of metastasis. In contrast, CD14+ monocyte-derived cells from patients with solid tumors have been shown to promote tumor progression. Therefore, understanding this monocytic heterogeneity as well as other unexplored roles (i.e. monocyte-mediated phagocytosis of tumor cells) is crucially important for malignancies with high rates of metastasis. Yet, the phenotypic and functional diversity of circulating monocytes in patients with metastatic solid malignancies is still largely unknown. In this study, we sought to characterize and compare peripheral blood monocytes obtained from healthy donors and patients with advanced stage solid tumors. Through flow cytometric analysis and functional assays, we determined the subpopulation distributions as well as the phagocytic and suppressive activities of the monocytic compartment in patients with advanced cancer and healthy controls. Providing new insights into their cancer-related functions, we highlight the need for consideration of circulating monocytes into immune-targeting approaches in metastatic solid malignancies.

Abstract
Metastasis is the leading cause of cancer-related deaths, and greater knowledge of the metastatic microenvironment is necessary to effectively target this process. Microenvironmental changes occur at distant sites prior to clinically detectable metastatic disease; however, the key niche regulatory signals during metastatic progression remain poorly characterized. Here, we identify a core immune suppression gene signature in pre-metastatic niche formation that is expressed predominantly by myeloid cells. We target this immune suppression program by utilizing genetically engineered myeloid cells (GEMys) to deliver IL-12 to modulate the metastatic microenvironment. Our data demonstrate that IL12-GEMy treatment reverses immune suppression in the pre-metastatic niche by activating antigen presentation and T cell activation, resulting in reduced metastatic and primary tumor burden and improved survival of tumor-bearing mice. We demonstrate that IL12-GEMys can functionally modulate the core program of immune suppression in the pre-metastatic niche to successfully rebalance the dysregulated metastatic microenvironment in cancer.

Abstract
Despite a remarkable increase in the genomic profiling of cancer, integration of genomic discoveries into clinical care has lagged behind. We report the feasibility of rapid identification of targetable mutations in 153 pediatric patients with relapsed/refractory or high-risk leukemias enrolled on a prospective clinical trial conducted by the LEAP Consortium. Eighteen percent of patients had a high confidence Tier 1 or 2 recommendation. We describe clinical responses in the 14% of patients with relapsed/refractory leukemia who received the matched targeted therapy. Further, in order to inform future targeted therapy for patients, we validated variants of uncertain significance, performed ex vivo drug-sensitivity testing in patient leukemia samples, and identified new combinations of targeted therapies in cell lines and patient-derived xenograft models. These data and our collaborative approach should inform the design of future precision medicine trials. SIGNIFICANCE: Patients with relapsed/refractory leukemias face limited treatment options. Systematic integration of precision medicine efforts can inform therapy. We report the feasibility of identifying targetable mutations in children with leukemia and describe correlative biology studies validating therapeutic hypotheses and novel mutations.See related commentary by Bornhauser and Bourquin, p. 1322.This article is highlighted in the In This Issue feature, p. 1307.

Abstract
BACKGROUND The treatment paradigm for patients with relapsed/refractory B-cell acute lymphoblastic leukemia (rrALL) has been revolutionized given recent clinical trials demonstrating remarkable success of immunotherapies and leading to drug approvals by United States and European agencies. We report experience with commercial blinatumomab and inotuzumab use at two North American pediatric oncology centers in children and adolescents/young adults with B-ALL. PROCEDURE Patients 0-25 years old treated with the CD19 × CD3 bispecific T cell-engaging antibody blinatumomab and/or the CD22 antibody-drug conjugate inotuzumab from January 1, 2010, to June 1, 2018, were eligible. Disease status included relapsed B-ALL in second or greater relapse, primary chemotherapy-refractory B-ALL, or B-ALL complicated by severe infection precluding delivery of conventional chemotherapy. RESULTS We identified 27 patients who received blinatumomab and/or inotuzumab outside of clinical trials during the study period. Four of the 13 patients (31%) with relapsed disease achieved minimal residual disease (MRD)-negative remission, and five patients (39%) underwent hematopoietic stem cell transplant (HSCT). In the 12 patients with primary chemorefractory B-ALL treated with immunotherapy, 11 (92%) achieved MRD-negative remission as assessed by flow cytometry; 10 patients (83%) underwent subsequent HSCT. Two patients with B-ALL in MRD-negative remission received blinatumomab due to severe infection and remained in remission after chemotherapy continuation. CONCLUSIONS Blinatumomab and inotuzumab can induce deep remissions in patients with rrALL and facilitate subsequent HSCT or other cellular therapies. Blinatumomab can also serve as an effective bridging therapy during severe infection. The optimal timing, choice of immunotherapeutic agent(s), and duration of responses require further investigation via larger-scale clinical trials.

Abstract
Allogeneic hematopoietic cell transplantation (HCT) for children with nonmalignant disorders is challenged by potential drug-related toxicities and poor engraftment. This retrospective analysis expands on our single pediatric medical center experience with targeted busulfan, fludarabine, and intravenous (IV) alemtuzumab as a low-toxicity regimen to achieve sustained donor engraftment. Sixty-two patients received this regimen for their first HCT for a nonmalignant disorder between 2004 and 2018. Donors were matched sibling in 27%, 8/8 HLA allele-matched unrelated in 50%, and 7/8 HLA allele-mismatched in 23% (some of whom received additional immunoablation with thiotepa or clofarabine). Five patients experienced graft failure for a cumulative incidence of 8.4% (95% CI, 1 to 16%). In engrafted patients, the median donor chimerism in whole blood and CD3, CD14/15, and CD19 subsets at 1-year were 96%, 90%, 99%, and 99%, respectively. Only one patient received donor lymphocyte infusions (DLIs) for poor chimerism. Two patients died following disease progression despite 100% donor chimerism. The 3-year cumulative incidence of treatment-related mortality was 10% (95% CI, 2 to 17%). Overall survival and event-free-survival at 3-years were 87% (95% CI, 78 to 95%) and 80% (95% CI, 70 to 90%), respectively. The 6-month cumulative incidence of grade II to IV acute graft-versus-host disease (GVHD) was 7% (95% CI, 3 to 13%), while the 3-year cumulative incidence of chronic GVHD was 5% (95% CI, 0 to 11%). These results suggest that use of targeted busulfan, fludarabine and IV alemtuzumab offers a well-tolerated option for children with nonmalignant disorders to achieve sustained engraftment with a low incidence of GVHD.

Abstract
The main component of the amyloid senile plaques found in Alzheimer's brain is the amyloid-beta-peptide (A beta), a proteolytic product of a membrane precursor protein. Previous structural studies have found different conformations for the A beta peptide depending on the solvent and pH used. In general, they have suggested an alpha-helix conformation at the N-terminal domain and a beta-sheet conformation for the C-terminal domain. The structure of the complete A beta peptide (residues 1-40) solved by NMR has revealed that only helical structure is present in A beta. However, this result cannot explain the large beta-sheet A beta aggregates known to form amyloid under physiological conditions. Therefore, we investigated the structure of A beta by molecular modeling based on extensive homology using the Smith and Waterman algorithm implemented in the MPsrch program (Blitz server). The results showed a mean value of 23% identity with selected sequences. Since these values do not allow a clear homology to be established with a reference structure in order to perform molecular modeling studies, we searched for detailed homology. A 28% identity with an alpha/beta segment of a triosephosphate isomerase (TIM) from Culex tarralis with an unsolved three-dimensional structure was obtained. Then, multiple sequence alignment was performed considering A beta, TIM from C.tarralis and another five TIM sequences with known three-dimensional structures. We found a TIM segment with secondary structure elements in agreement with previous experimental data for A beta. Moreover, when a synthetic peptide from this TIM segment was studied in vitro, it was able to aggregate and to form amyloid fibrils, as established by Congo red binding and electron microscopy. The A beta model obtained was optimized by molecular dynamics considering ionizable side chains in order to simulate A beta in a neutral pH environment. We report here the structural implications of this study.
