Impact of Cytomegalovirus Replication in Patients with Aggressive B Cell Lymphoma Treated with Chimeric Antigen Receptor T Cell Therapy. Transplant Cell Ther 2022; 28:851.e1-851.e8. [PMID: 36221995 DOI: 10.1016/j.jtct.2022.09.007] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 08/14/2022] [Accepted: 09/14/2022] [Indexed: 02/07/2023]
Abstract
Data are scarce on cytomegalovirus (CMV) replication in patients receiving CD19-directed chimeric antigen receptor (CAR) T cell treatment. Here we describe the incidence, severity, and management of CMV infection in patients with aggressive B cell lymphoma treated with CAR T cell therapy. In this retrospective observational study, we analyzed CMV viral load and its clinical impact in patients with aggressive B cell lymphoma receiving CAR T cell therapy between July 2018 and December 2021 at a single center. Patients with a negative baseline CMV IgG or a previous allogeneic stem cell transplantation were excluded. CMV replication was determined in whole blood. Overall, 105 patients met the study's inclusion criteria. Ten patients presented with CMV replication before CAR T cell infusion and were analyzed separately. Forty-two of the remaining 95 patients (44%) had at least 1 positive CMV determination, with a viral load ≥1000 IU/mL in 21 patients (22%). Four patients in the main cohort (N = 95) and 4 patients in the preinfusion replication group (N = 10) achieved a viral load >10,000 IU/mL. Only 7 patients received preemptive antiviral treatment. No CMV end-organ disease was reported. The sole independent risk factor associated with CMV viremia ≥1000 IU/mL was dexamethasone treatment (odds ratio, 8.4; 95% confidence interval, 2.4 to 36.6; P = .002). Based on our findings, we designed an algorithm for CMV management in this setting. CMV replication is relatively frequent in patients with aggressive B cell lymphoma receiving CAR T cell therapy. It is usually self-limited and not associated with end-organ disease. Patients receiving dexamethasone or harboring CMV replication before infusion might benefit from active surveillance and preemptive treatment strategies.

Abstract
Here, we report the first comparative analysis of patient-reported outcomes (PROs) with chimeric antigen receptor T-cell therapy vs standard-of-care (SOC) therapy in second-line relapsed/refractory large B-cell lymphoma (R/R LBCL) from the pivotal randomized phase 3 ZUMA-7 study of axicabtagene ciloleucel (axi-cel) vs SOC. PRO instruments were administered at baseline, day 50, day 100, day 150, month 9, and every 3 months from randomization until 24 months or an event-free survival event. The quality of life (QoL) analysis set comprised patients with a baseline and ≥1 follow-up PRO completion. Prespecified hypotheses for Quality of Life Questionnaire-Core 30 (QLQ-C30) physical functioning, global health status/QoL, and EQ-5D-5L visual analog scale (VAS) were tested using mixed-effects models with repeated measures. Clinically meaningful changes were defined as 10 points for QLQ-C30 and 7 for EQ-5D-5L VAS. Among 359 patients, 296 (165 axi-cel, 131 SOC) met inclusion criteria for QoL analysis. At day 100, statistically significant and clinically meaningful differences in mean change of scores from baseline were observed favoring axi-cel over SOC for QLQ-C30 global health status/QoL (estimated difference 18.1 [95% confidence interval (CI), 12.3-23.9]), physical functioning (13.1 [95% CI, 8.0-18.2]), and EQ-5D-5L VAS (13.7 [95% CI, 8.5-18.8]; P < .0001 for all). At day 150, scores significantly favored axi-cel vs SOC for global health status/QoL (9.8 [95% CI, 2.6-17.0]; P = .0124) and EQ-5D-5L VAS (11.3 [95% CI, 5.4-17.1]; P = .0004). Axi-cel showed clinically meaningful improvements in QoL over SOC. Superior clinical outcomes and favorable patient experience with axi-cel should help inform treatment choices in second-line R/R LBCL. This trial was registered at www.clinicaltrials.gov as #NCT03391466.

Abstract
The ZUMA-7 (Efficacy of Axicabtagene Ciloleucel Compared to Standard of Care Therapy in Subjects With Relapsed/Refractory Diffuse Large B Cell Lymphoma) study showed that axicabtagene ciloleucel (axi-cel) improved event-free survival (EFS) compared with standard of care (SOC) salvage chemoimmunotherapy followed by autologous stem cell transplant in primary refractory/early relapsed diffuse large B-cell lymphoma (DLBCL); this led to its recent US Food and Drug Administration approval in this setting. We modeled a hypothetical cohort of US adults (mean age, 65 years) with primary refractory/early relapsed DLBCL by developing a Markov model (lifetime horizon) to model the cost-effectiveness of second-line axi-cel compared with SOC using a range of plausible long-term outcomes. EFS and OS were estimated from ZUMA-7. Outcome measures were reported in incremental cost-effectiveness ratios, with a willingness-to-pay (WTP) threshold of $150 000 per quality-adjusted life-year (QALY). Assuming a 5-year EFS of 35% with second-line axi-cel and 10% with SOC, axi-cel was cost-effective at a WTP of $150 000 per QALY ($93 547 per QALY). axi-cel was no longer cost-effective if its 5-year EFS was ≤26.4% or if it cost more than $972 061 at a WTP of $150 000. Second-line axi-cel was the cost-effective strategy in 73% of the 10 000 Monte Carlo iterations at a WTP of $150 000. If the absolute benefit in EFS is maintained over time, second-line axi-cel for aggressive relapsed/refractory DLBCL is cost-effective compared with SOC at a WTP of $150 000 per QALY. However, its cost-effectiveness is highly dependent on long-term outcomes. Routine use of second-line chimeric antigen receptor T-cell therapy would add significantly to health care expenditures in the United States (more than $1 billion each year), even when used in a high-risk subpopulation. Further reductions in the cost of chimeric antigen receptor T-cell therapy are needed to be affordable in many regions of the world.

Abstract
BACKGROUND Patients with Diffuse Large Bcell Lymphoma (DLBCL) with MYC and BCL2 and/or BCL6 gene rearrangements [double-hit lymphoma/triple-hit lymphoma (DHL/THL)] have poor prognosis in the relapsed/refractory setting. METHODS We utilized a real-world deidentified database of DLBCL patients and report patterns of therapy utilization in relapsed/refractory DLBCL. We used log-rank test to compare real-world overall survival (rwOS) among DHL and non-DHL subgroups for CAR Tcell therapy or ASCT respectively, stratified for prior lines of therapy. RESULTS Of all 7,877 patients with DLBCL, 367 patients had DHL while 6113 had non-DHL. Second line chemotherapy was administered to 147 DHL patients and 1517 non-DHL. 1393 were excluded, including 934 with unknown DHL/THL status. Approximately 47% received salvage intent chemotherapy in the DHL subgroup, of which 19% patients eventually received ASCT, while 34% received salvage intent chemotherapy in the non-DHL/THL group with 32% receiving ASCT. DHL/THL status negatively influenced median rwOS for patients who underwent ASCT in the second-line while it was associated with numerically inferior but without statistically significant rwOS among patients that underwent CAR Tcell therapy on multivariable analysis. CONCLUSION rwOS of relapsed DHL/THL is inferior to non-DHL/THL. Fewer patients with DHL/THL were able to proceed with ASCT after salvage chemotherapy compared to non-DHL/THL. ASCT as second-line therapy for relapsed DHL/THL had worse rwOS than for non-DHL/THL, consistent with the natural history of DHL/THL. This difference was not seen for CAR Tcell therapy, which combined with promising results from clinical trials, suggests a greater role for CAR T-cell therapy in relapsed/refractory DHL.

Abstract
INTRODUCTION Gemcitabine-based regimens are effective salvage therapy for RR lymphoma patients eligible for ASCT, but there is limited data in transplant-ineligible (TIE) patients. Here, we present a retrospective analysis on the outcome of TIE adult patients with RR lymphoma treated with gemcitabine, cisplatin or carboplatin and dexamethasone (GDP/GDCarboP) +/- rituximab regimen in our center. PATIENTS We identified 33 patients: 54.5% diffuse large Bcell lymphoma (DLBCL), 6.1% double/triple hit lymphoma, 15% follicular lymphoma, 18% T-cell lymphoma, and 6% classical Hodgkin lymphoma. Majority of the patients had advanced-stage disease and raised LDH at relapse. The cohort's median age was 71 years. The median number of prior lines of treatment was 2, and 60.6% were refractory to their last line of treatment. RESULTS The overall response rate was 33% (complete response 15%) for the entire cohort and 62.5% for DLBCL patients not refractory to prior line of treatment. At median follow-up of 25 months, the median duration of response and overall survival in the responders were not reached. Conversely, the median overall survival for the non-responders was dismal at 5 months. Fifty-five percent required treatment alteration (dose attenuation or omission and treatment delay for >1 week) due to adverse events, 73% needed transfusion, and 70% had at least 1 hospital admission during treatment. CONCLUSION Our real-world data showed that GDP/GDCarboP provides meaningful efficacy and durability, especially among the responders. However, dose modification and inpatient support are frequently needed, indicating the need for good supportive care and close follow-up in this frailer population.

Abstract
BACKGROUND Chimeric antigen receptor (CAR) T-cell therapy has emerged as a promising treatment option for relapsed or refractory B-cell malignancies and multiple myeloma. Underlying and treatment-related variables may contribute to the development of infectious complications. RESEARCH DESIGN AND METHODS We conducted a systematic review and meta-analysis on the incidence of overall and severe (grade ≥3) infection in patients with hematological malignancies receiving CAR T-cells. Secondary outcomes included the specific rates of bacterial, viral and invasive fungal infection (IFI), and infection-related mortality. PubMed, Embase and Web of Science databases were searched from inception to 27 May 2022. Sensitivity analysis were performed according to the type of malignancy and study design (randomized clinical trials [RCTs] or observational studies). RESULTS Forty-five studies (34 RCTs) comprising 3,591 patients were included. The pooled incidence rates of overall and severe infection were 33.8% (I2 = 96.31%) and 16.2% (I2 = 74.41%). The respiratory tract was the most common site of infection. Most events were bacterial or viral, whereas the occurrence of IFI was rare. The pooled attributable mortality was 1.8% (I2 = 43.44%). CONCLUSIONS Infection is a frequent adverse event in patients receiving CAR T-cell therapy. Further research should address specific risk factors in this population.

Abstract
CAR T-cell therapy has transformed the treatment of hematological malignancies of the B cell lineage. However, the quest to fulfil the same promise for solid tumors is still in its infancy. This review summarizes some of the challenges that the field is trying to overcome for effective treatment of human carcinomas, including tumor heterogeneity, the paucity of truly tumor-specific targets, immunosuppression and metabolic restrictions at solid tumor beds, and defective T-cell trafficking. All these barriers are being currently investigated and, in some cases, targeted, by multiple independent groups. With clinical interventions against multiple human malignancies and different platforms under accelerated clinical development, the next few years will see an array of cellular therapies, including CAR T-cells, progressively becoming routine interventions to eliminate currently incurable diseases, as it happened with some hematological malignancies.

Abstract
Was ist neu?
DLBCL. Biologie Der kürzlich publizierte „LymphGen-Algorithmus“ differenziert 7 genetische Subtypen, die sich in der Aktivierung onkogener Signalwege, im Genexpressionsmuster, im Tumormikromilieu, der Überlebenswahrscheinlichkeit und potenzieller zielgerichteter Therapien unterscheiden.
Erstlinientherapie Der Einsatz des neuen Antikörper-Wirkstoff-Konjugats Polatuzumab-Vedotin (6 Zyklen der Kombination aus Polatuzumab + R-CHP) waren der bisherigen Erstlinien-Standardtherapie mit R-CHOP hinsichtlich 2-Jahres-PFS überlegen. Subgruppenanalysen wiesen vor allem auf eine Wirksamkeit bei Patienten mit Hochrisikofaktoren hin.
Rezidivtherapie Seit Kurzem steht mit dem gegen den CD19 gerichteten Antikörper Tafasitamab in Kombination mit dem Immunmodulator Lenalidomid eine wirksame Rezidivtherapie für jene Patientengruppe zur Verfügung, die für eine Hochdosistherapie nicht geeignet ist. In 2 Phase-III-Studien wurde kürzlich bereits im 1. Rezidiv eine Überlegenheit von CAR-T-Zellen gegenüber dem bisherigen Standard der Hochdosistherapie, gefolgt von aPBSCT, gezeigt. Mit den bispezifischen, T-Zell-rekrutierenden CD3 / CD20-Antikörpern Mosunetuzumab, Epcoritamab und Glofitamab sind derzeit weitere vielversprechende immuntherapeutische Ansätze Gegenstand aktueller Phase I/II-Studien.
MCL. Biologie Trotz der weiteren Entschlüsselung des genetischen Hintergrunds des MCL ist weiterhin nur für TP53 eine klinische Relevanz nachgewiesen.
Erstlinientherapie In der Ära der zielgerichteten Therapiestrategien wird derzeit die Bedeutung des BTK-Inhibitors Ibrutinib für die Erstlinien- und Erhaltungstherapie des MCL evaluiert. Für ältere Patienten erwies sich kürzlich die Kombination des Proteasom-Inhibitors Bortezomib, Rituximab, Cyclophosphamid, Doxorubicin und Prednisolon (VR-CAP) der bisherigen Standardtherapie mit R-CHOP überlegen. Für ältere Patienten, die für intensivere Therapieregime nicht geeignet sind, führte die Erweiterung des klassischen Regimes Rituximab + Bendamustin um Ibrutinib zu einer deutlichen Verbesserung des PFS.
Rezidivtherapie Für das rezidivierte/refraktäre MCL wurden neben dem seit Jahren zugelassenen Ibrutinib kürzlich auch die beiden Next-Generation-BTK-Inhibitoren Acalabrutinib and Zanubrutinib zugelassen. Der bcl1-Inhibitor Venetoclax bietet für Hochrisikopatienten, die nach vorangegangener Therapie mit Ibrutinib ein Rezidiv erlitten, eine vielversprechende Behandlungsmöglichkeit. Bezüglich immuntherapeutischer Therapieansätze erfolgte kürzlich die Zulassung des CD19-CAR-T-Zell-Konstrukts Brexucabtagene autoleucel ab dem 2. Rezidiv.

Cellular therapy modalities, including autologous (auto-) hematopoietic cell transplantation (HCT), allogeneic (allo-) HCT, and now chimeric antigen receptor (CAR) T cell therapy, have demonstrated long-term remission in advanced hematologic malignancies. Auto-HCT and allo-HCT, through hematopoietic rescue, have permitted the use of higher doses of chemotherapy. Allo-HCT also introduced a nonspecific immune-mediated targeting of malignancy resulting in protection from relapse, although at the expense of similar targeting of normal host cells. In contrast, CAR T therapy, through genetically engineered immunotherapeutic precision, allows for redirection of autologous immune effector cells against malignancy in an antigen-specific and MHC-independent fashion, with demonstrated efficacy in patients who are refractory to cytotoxic chemotherapy. It too has unique toxicities and challenges, however. Non-Hodgkin lymphoma (including large B cell lymphoma, mantle cell lymphoma, and follicular lymphoma), B cell acute lymphoblastic leukemia, and multiple myeloma are the 3 main diseases associated with the use of fully developed CAR T products with widespread deployment. Recent and ongoing clinical trials have been examining the interface among the 3 cellular therapy modalities (auto-HCT, allo-HCT, and CAR T) to determine whether they should be "complementary" or "competitive" therapies. In this review, we examine the current state of this interface with respect to the most recent data and delve into the controversies and conclusions that may inform clinical decision making.

Effect of granulocyte colony-stimulating factor on toxicities after CAR T cell therapy for lymphoma and myeloma. Blood Cancer J 2022; 12:146. [PMID: 36316312 PMCID: PMC9622902 DOI: 10.1038/s41408-022-00741-2] [Citation(s) in RCA: 23] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 09/30/2022] [Accepted: 10/06/2022] [Indexed: 11/17/2022] Open
Abstract
Chimeric antigen receptor T cells (CAR T) are groundbreaking therapies but may cause significant toxicities including cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), and cytopenias. Granulocyte colony-stimulating factor (G-CSF) is often used to mitigate neutropenia after CAR T, but there is no consensus recommended strategy due to hypothesized, but largely unknown risks of exacerbating toxicities. To investigate the impact of G-CSF, we retrospectively analyzed 197 patients treated with anti-CD19 CAR T for lymphoma and 47 patients treated with anti-BCMA CAR T for multiple myeloma. In lymphoma, 140 patients (71%) received prophylactic G-CSF before CAR T (mostly pegylated G-CSF) and were compared with 57 patients (29%) treated with G-CSF after CAR T or not exposed. Prophylactic G-CSF was associated with faster neutrophil recovery (3 vs. 4 days, P < 0.01) but did not reduce recurrent neutropenia later. Prophylactic G-CSF was associated with increased grade ≥2 CRS (HR 2.15, 95% CI 1.11-4.18, P = 0.02), but not ICANS. In multiple myeloma, prophylactic G-CSF was not used; patients were stratified by early G-CSF exposure (≤2 days vs. ≥3 days after CAR T or no exposure), with no significant difference in toxicities. Future trials should clarify the optimal G-CSF strategy to improve outcomes after CAR T.

Abstract
Adoptive cell therapy (ACT) and chimeric antigen receptor (CAR) T cell therapy in particular represents an adaptive, yet versatile strategy for cancer treatment. Convincing results in the treatment of hematological malignancies have led to FDA approval for several CAR T cell therapies in defined refractory diseases. In contrast, the treatment of solid tumors with adoptively transferred T cells has not demonstrated convincing efficacy in clinical trials. One of the main reasons for ACT failure in solid tumors is poor trafficking or access of transferred T cells to the tumor site. Tumors employ a variety of mechanisms shielding themselves from immune cell infiltrates, often translating to only fractions of transferred T cells reaching the tumor site. To overcome this bottleneck, extensive efforts are being undertaken at engineering T cells to improve ACT access to solid tumors. In this review, we provide an overview of the immune cell infiltrate in human tumors and the mechanisms tumors employ toward immune exclusion. We will discuss ways in which T cells can be engineered to circumvent these barriers. We give an outlook on ongoing clinical trials targeting immune cell migration to improve ACT and its perspective in solid tumors.

Abstract
The development of chimeric antigen receptor (CAR)-T cell therapy has revolutionized the treatment of hematological diseases. However, approximately 60% of patients relapse after CAR-T cell therapy, and no clear cause for this failure has been identified. The objective of the Bio-CAR-T BS study (ClinicalTrials.gov: NCT05366569) is to improve our understanding of the lymphocyte harvest to maximize the quality of the CAR-T cell product. Of the 14 patients enrolled, 11 were diagnosed with DLBCL, 2 with PMBCL, and 1 with ALL. Five of 11 DLBCL patients met the criteria for "pre-emptive" Lymphocytes-apheresis (being at high risk of second relapse), and 6 were included in the standard-of-care Lymphocytes-apheresis group. Previous autologous stem cell transplantation (ASCT) and age were significantly different between the two groups. At the time of Lymphocyte-apheresis, patients in the "pre-emptive" group had more "fit" lymphocytes (higher CD4+/CD8+ ratio; higher naïve T cells levels) compared with standard group, probably due to the impact of ASCT. At the same time, also being older than 60 years results in a more "exhausted" lymphocyte profile. Overall, "pre-emptive" Ly-apheresis in DLBCL patients at high risk of relapse appears to be feasible and may allow the timely collection of "fit" lymphocytes for CAR-T cell manufacturing.

Abstract
Chimeric antigen receptor (CAR) T cell (CAR-T cell) therapy based on gene editing technology represents a significant breakthrough in personalized immunotherapy for human cancer. This strategy uses genetic modification to enable T cells to target tumor-specific antigens, attack specific cancer cells, and bypass tumor cell apoptosis avoidance mechanisms to some extent. This method has been extensively used to treat hematologic diseases, but the therapeutic effect in solid tumors is not ideal. Tumor antigen escape, treatment-related toxicity, and the immunosuppressive tumor microenvironment (TME) limit their use of it. Target selection is the most critical aspect in determining the prognosis of patients receiving this treatment. This review provides a comprehensive summary of all therapeutic targets used in the clinic or shown promising potential. We summarize CAR-T cell therapies’ clinical trials, applications, research frontiers, and limitations in treating different cancers. We also explore coping strategies when encountering sub-optimal tumor-associated antigens (TAA) or TAA loss. Moreover, the importance of CAR-T cell therapy in cancer immunotherapy is emphasized.

Abstract
Histological transformation (HT) to an aggressive lymphoma results from a rare evolution of Waldenström macroglobulinemia (WM). A higher incidence of transformation events has been reported in MYD88 wild-type WM patients. HT in WM can be histologically heterogeneous, although the diffuse large B-cell lymphoma of activated B-cell subtype is the predominant pathologic entity. The pathophysiology of HT is largely unknown. The clinical suspicion of HT is based on physical deterioration and the rapid enlargement of the lymph nodes in WM patients. Most transformed WM patients present with elevated serum lactate dehydrogenase (LDH) and extranodal disease. A histologic confirmation regarding the transformation to a higher-grade lymphoma is mandatory for the diagnosis of HT, and the choice of the biopsy site may be dictated by the findings of the 18fluorodeoxyglucose-positron emission tomography/computed tomography. The prognosis of HT in WM is unfavorable, with a significantly inferior outcome compared to WM patients without HT. A validated prognostic score based on 3 adverse risk factors (elevated LDH, platelet count < 100 × 109/L and any previous treatment for WM) stratifies patients into 3 risk groups. The most common initial treatment used is a chemo-immunotherapy (CIT), such as R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). The response duration is short and central nervous system relapses are frequent. Whether autologous stem cell transplantation could benefit fit patients responding to CIT remains to be studied.

Abstract
Secondary CNS lymphoma (SCNSL) is a rare but frequently fatal complication of systemic lymphoma. There is no standard treatment for SCNSL, and patients who develop SCNSL at diagnosis or after frontline therapy often receive highly intensive chemotherapy regimens that are inactive against primary chemorefractory disease and too toxic for older, frail patients to tolerate. Because the prognosis of SCNSL is so poor, management has historically emphasized prevention, but the current methods of CNS prophylaxis are not universally effective. To improve both the prevention and management of SCNSL, better characterization of the molecular determinants of CNS invasion is needed. Novel treatments that are currently being studied in SCNSL include targeted pathway inhibitors and cellular therapy, but SCNSL patients are often excluded from clinical trials of promising new therapies.

Abstract
Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) have both demonstrated impressive clinical activity in relapsed/refractory (R/R) diffuse large B cell lymphoma (DLBCL). In this study, we analyzed the outcome of 809 patients with R/R DLBCL after two or more previous lines of treatment who had a commercial chimeric antigen receptor (CAR) T cells order for axi-cel or tisa-cel and were registered in the retrospective French DESCAR-T registry study ( NCT04328298 ). After 1:1 propensity score matching (n = 418), the best overall response rate/complete response rate (ORR/CRR) was 80%/60% versus 66%/42% for patients treated with axi-cel compared to tisa-cel, respectively (P < 0.001 for both ORR and CRR comparisons). After a median follow-up of 11.7 months, the 1-year progression-free survival was 46.6% for axi-cel and 33.2% for tisa-cel (hazard ratio (HR) = 0.61; 95% confidence interval (CI), 0.46-0.79; P = 0.0003). Overall survival (OS) was also significantly improved after axi-cel infusion compared to after tisa-cel infusion (1-year OS 63.5% versus 48.8%; HR = 0.63; 95% CI, 0.45-0.88; P = 0.0072). Similar findings were observed using the inverse probability of treatment weighting statistical approach. Grade 1-2 cytokine release syndrome was significantly more frequent with axi-cel than with tisa-cel, but no significant difference was observed for grade ≥3. Regarding immune effector cell-associated neurotoxicity syndrome (ICANS), both grade 1-2 and grade ≥3 ICANS were significantly more frequent with axi-cel than with tisa-cel. In conclusion, our matched comparison study supports a higher efficacy and also a higher toxicity of axi-cel compared to tisa-cel in the third or more treatment line for R/R DLBCL.

Abstract
Lymphomas are among the most common cancers in people with HIV (PWH). The lymphoma subtypes and pathogenesis of lymphoma in PWH are different from the immunocompetent population. It is well-known that HIV causes severe CD4+ T cell lymphopenia in the absence of antiretroviral therapy (ART); however, the risk of developing certain subtypes of lymphoma remains elevated even in people receiving ART with preserved CD4+ T cells. HIV contributes to lymphomagenesis and causes decreased immune surveillance via T cell depletion and dysregulation, B cell dysregulation, and the potential contribution of HIV-encoded proteins. The oncogenic gammaherpesviruses, Epstein-Barr virus (EBV) and Kaposi sarcoma herpesvirus (KSHV, also known as human herpesvirus 8), are the causative agents in the majority of HIV-associated lymphomas. HIV-associated T cell depletion and dysregulation allows EBV and KSHV to proliferate in infected B cells. Specific EBV- and KSHV-encoded proteins participate in B cell activation, and proliferation leading to B cell transformation. Understanding the distinct pathogenesis of HIV-associated lymphomas affords opportunities to develop therapies that specifically target these unique aspects and improve lymphoma outcomes in PWH. Agents being studied that target the specific roles of HIV, EBV, and KSHV in lymphomagenesis include immunotherapies, targeted agents, and cellular therapies.

Abstract
Chimeric antigen receptor (CAR) T cell therapy represents a significant advancement in the treatment of patients with relapsed/refractory B cell lymphoid malignancies. Cytokine release syndrome and immune effector cell-associated neurotoxicity represent the most acute serious adverse events post CAR T cell therapy but the occurrence and persistence of cytopenias post CAR T cell therapy represent a significant adverse event and a management challenge. While most patients typically recover blood counts by 30 days, a significant subset of patients have persistent or late cytopenias beyond 30 days. Patients receiving CAR T cell are heavily pre-treated and the impact of prior therapies on late cytopenias is not well understood. In this study, we found an association between increased number of rituximab infusions and/or cumulative rituximab dose received prior to CAR T cell infusion and persistent anemia and thrombocytopenia at 90 and 180 days afterwards. An overall increased number of prior lines of therapy was also associated with persistent lymphopenia and anemia at 90 days while receiving a prior autologous hematopoietic cell transplant was associated with a greater risk of neutropenia and lymphopenia.

Abstract
Although chimeric antigen receptor (CAR) T-cell therapy has shown a high response rate in lymphoma patients, its cost-effectiveness is controversial due to the high price and uncertainty of the clinical evidence. In addition to the high acquisition cost of CAR T-cell therapy, procedure and facility cost increase the financial burden considering the frequency of adverse events such as cytokine release syndrome. In clinical research, relatively short follow-up periods were used compared to traditional cancer agents. In addition, head-to-head comparative effectiveness data are unavailable, which is an important factor when evaluating the cost-effectiveness of a new treatment. Additional evidence that will compensate for the uncertainty of existing clinical data is needed for full evaluation of long-term efficacy, safety, and comparative effectiveness.

Abstract
Chimeric antigen receptor (CAR)-T cells are engineered to identify and eliminate cells expressing a target antigen. Current manufacturing protocols vary between commercial CAR-T cell products warranting an assessment of these methods to determine which approach optimally balances successful manufacturing capacity and product efficacy. One difference between commercial product manufacturing methods is whether T cell engineering begins with fresh (unfrozen) patient cells or cells that have been cryopreserved prior to manufacture. Starting with frozen PBMC material allows for greater manufacturing flexibility, and the possibility of collecting and storing blood from patients prior to multiple lines of therapy. We prospectively analyzed if second generation anti-CD19 CAR-T cells with either CD28 or 4-1BB co-stimulatory domains have different phenotype or function when prepared side-by-side using fresh or cryopreserved PBMCs. We found that cryopreserved PBMC starting material is associated with slower CAR-T cell expansion during manufacture but does not affect phenotype. We also demonstrate that CAR-T cell activation, cytokine production and in vitro anti-tumor cytotoxicity were not different when CAR-T cells were manufactured from fresh or cryopreserved PBMC. As CAR-T cell therapy expands globally, the need for greater flexibility around the timing of manufacture will continue to grow. This study helps support the concept that cryopreservation of PBMCs could be the solution to these issues without compromising the quality of the final CAR-T product.

Abstract
Tafasitamab and lenalidomide were approved for second-line treatment of diffuse large B-cell lymphoma (DLBCL) based on a single-arm phase II study. This combination was superior to routine immunochemotherapy regimens when comparing matched observational cohorts. "Synthetic" control groups may support use of novel DLBCL therapies in the absence of randomized studies. See related article by Nowakowski et al., p. 4003.

Abstract
The therapeutic landscape for lymphomas is quite diverse and includes active surveillance, chemotherapy, immunotherapy, radiation therapy, and even stem cell transplant. Advances in the field have led to the development of targeted therapies, agents that specifically act against a specific component within the critical molecular pathway involved in tumorigenesis. There are currently numerous targeted therapies that are currently Food and Drug Administration (FDA) approved to treat certain lymphoproliferative disorders. Of many, some of the targeted agents include rituximab, brentuximab vedotin, polatuzumab vedotin, nivolumab, pembrolizumab, mogamulizumab, vemurafenib, crizotinib, ibrutinib, cerdulatinib, idelalisib, copanlisib, venetoclax, tazemetostat, and chimeric antigen receptor (CAR) T-cells. Although these agents have shown strong efficacy in treating lymphoproliferative disorders, the complex biology of the tumors have allowed for the malignant cells to develop various mechanisms of resistance to the targeted therapies. Some of the mechanisms of resistance include downregulation of the target, antigen escape, increased PD-L1 expression and T-cell exhaustion, mutations altering the signaling pathway, and agent binding site mutations. In this manuscript, we discuss and highlight the mechanism of action of the above listed agents as well as the different mechanisms of resistance to these agents as seen in lymphoproliferative disorders.

Abstract
CAR-T cell therapies have been recognized as one of the most advanced and efficient strategies to treat patients with hematologic malignancies. However, similar results have not been observed for the treatment of solid tumors. One of the explanations is the fact that tumors have extremely hostile microenvironments for the infiltration and effector activity of T-cells, mainly due to the presence of highly suppressive cytokines, hypoxia, and reactive oxygen species. Taking advantage of cytokines functionally, new fourth-generation CAR constructs have been developed to target tumor cells and additionally release cytokines that can contribute to the cytotoxicity of T-cells. The manufacturing process, including the use of cytokines in the expansion and differentiation of T cells, is also discussed. Finally, the clinical aspects and the influence of cytokines on the clinical condition of patients, such as cytokine release syndrome, who receive treatment with CAR-T cells are addressed. Therefore, this review aims to highlight how important cytokines are as one of the major players of cell therapy.

Abstract
Purpose High tumor burden has emerged as a negative predictor of efficacy in chimeric antigen receptor T-cell therapy (CART) in patients with refractory or relapsed large B-cell lymphoma. This study analyzed the deviation among imaging-based tumor burden (TB) metrics and their association with progression-free (PFS) and overall survival (OS). Materials and methods In this single-center observational study, we included all consecutively treated patients receiving CD19 CART with available baseline PET-CT imaging. Imaging-based TB was determined based on response evaluation criteria in lymphoma (RECIL), the Lugano criteria, and metabolic tumor volume. Total, nodal and extranodal TB were represented, according to the respective criteria, by sum of longest diameters (TBRECIL), sum of product of perpendicular diameters (TBLugano), and metabolic tumor volume (TBMTV). Correlation statistics were used for comparison. Proportional Cox regression analysis studied the association of TB metrics with PFS and OS. Results 34 consecutive patients were included (median age: 67 years, 41% female) with total median baseline TBRECIL of 12.5 cm, TBLugano of 4,030 mm2 and TBMTV of 330 mL. The correlation of TBRECIL and TBLugano with TBMTV was strong (ρ=0.744, p<0.001 and ρ=0.741, p<0.001), with lowest correlation for extranodal TBRECIL with TBMTV (ρ=0.660, p<0.001). Stratification of PFS was strongest by total TBMTV>50% (HR=2.915, p=0.042), whereas total TBRECIL>50% and total TBLugano>50% were not significant (both p>0.05). None of the total TB metrics were associated with OS (all p>0.05). Conclusion Pre-CART TB metrics vary significantly based on the assessment method, impacting their association with survival outcomes. The correlation between TBRECIL, TBLugano and TBMTV was influenced by disease phenotype and prior bridging therapy. TB method of assessment must be considered when interpreting the impact of TB on outcomes in clinical trials. Considering the heterogeneity, our results argue for standardization and harmonization across centers.

Abstract
Chimeric antigen receptor T-cell therapy (CAR-T) is a major advance in managing aggressive relapsed or refractory B-cell lymphomas; however, relapses are frequent and pose a major therapeutic challenge. There is substantial variability across transplantation and cellular therapy programs in assessing and managing post-CAR-T failures. The American Society for Transplantation and Cellular Therapy Committee on Practice Guidelines conducted an online cross-sectional survey between August 2021 and October 2021 to determine the U.S. lymphoma and transplantation and cellular therapy physicians' practice patterns for the detection and diagnosis of CAR-T failure, as well as management strategies for diffuse large B-cell lymphoma in this particular setting. E-mail surveys were sent to 901 potential participants, of which 174 (19%) completed the survey. Responders were mainly White (51.2%), male (70.7%), and with >10 years of practice experience (51.2%). Overall, 87% of the responders were affiliated with university/teaching centers; 54.6% had general oncology practices, and 45.4% had lymphoma-focused transplantation/cellular therapy practices. The most common periods to perform surveillance scans were at 3 months and 12 months after CAR-T infusion. Overall, 88.5% of responders would often or always consider a biopsy to confirm relapse and 89% would routinely check for the persistence of the antigen targeted by the CAR (e.g., CD19 in the case of CD19 CAR-T). The most popular first salvage regimen for relapse or progression was an alternate CAR-T therapy (dual or alternate target) regardless of CD19 positivity. Twenty-seven percent of responders chose this regimen for CD19 positive relapse, whereas 31% of responders did so for CD19 negative relapse. Overall, 88.5% of responders favored consolidative allogeneic hematopoietic cell transplantation after response to salvage, whereas 51.2% of physicians would consider autologous hematopoietic cell transplantation in transplantation-naïve patients. There is substantial cross-center variation in surveillance, diagnosis, and management of CAR-T failure. Prospective clinical trials evaluating novel agents in this setting are urgently needed to identify best management strategies.

Abstract
Approximately 60% of patients with large B cell lymphoma treated with chimeric antigen receptor (CAR) T cell therapies targeting CD19 experience disease progression, and neurotoxicity remains a challenge. Biomarkers associated with resistance and toxicity are limited. In this study, single-cell proteomic profiling of circulating CAR T cells in 32 patients treated with CD19-CAR identified that CD4+Helios+ CAR T cells on day 7 after infusion are associated with progressive disease and less severe neurotoxicity. Deep profiling demonstrated that this population is non-clonal and manifests hallmark features of T regulatory (TReg) cells. Validation cohort analysis upheld the link between higher CAR TReg cells with clinical progression and less severe neurotoxicity. A model combining expansion of this subset with lactate dehydrogenase levels, as a surrogate for tumor burden, was superior for predicting durable clinical response compared to models relying on each feature alone. These data credential CAR TReg cell expansion as a novel biomarker of response and toxicity after CAR T cell therapy and raise the prospect that this subset may regulate CAR T cell responses in humans.

Abstract
Advances in immuno-oncology have provided a variety of novel therapeutics that harness the innate immune system to identify and destroy neoplastic cells. It is noteworthy that acceptable safety profiles accompany the development of these targeted therapies, which result in efficacious cancer treatment with higher survival rates and lower toxicities. Adoptive cellular therapy (ACT) has shown promising results in inducing sustainable remissions in patients suffering from refractory diseases. Two main types of ACT include engineered Chimeric Antigen Receptor (CAR) T cells and T cell receptor (TCR) T cells. The application of these immuno-therapies in the last few years has been successful and has demonstrated a safe and rapid treatment regimen for solid and non-solid tumors. The current review presents an insight into the clinical pharmacology aspects of immuno-therapies, especially CAR-T cells. Here, we summarize the current knowledge of TCR and CAR-T cell immunotherapy with particular focus on the structure of CAR-T cells, the effects and toxicities associated with these therapies in clinical trials, risk mitigation strategies, dose selection approaches, and cellular kinetics. Finally, the quantitative approaches and modeling techniques used in the development of CAR-T cell therapies are described.

Abstract
Noninvasive disease monitoring and risk stratification by circulating tumor DNA (ctDNA) profiling has become a potential novel strategy for patient management in B-cell lymphoma. Emerging innovative therapeutic options and an unprecedented growth in our understanding of biological and molecular factors underlying lymphoma heterogeneity have fundamentally increased the need for precision-based tools facilitating personalized and accurate disease profiling and quantification. By capturing the entire mutational landscape of tumors, ctDNA assessment has some decisive advantages over conventional tissue biopsies, which usually target only one single tumor site. Due to its non- or minimal-invasive nature, serial and repeated ctDNA profiling provides a real-time picture of the genetic composition and facilitates quantification of tumor burden any time during the course of the disease. In this review, we present a comprehensive overview of technologies used for ctDNA detection and genotyping in B-cell lymphoma, focusing on pre-analytical and technical requirements, the advantages and limitations of various approaches, and highlight recent advances around improving sensitivity and suppressing technical errors. We broadly review potential applications of ctDNA in clinical practice and for translational research by describing how ctDNA might enhance lymphoma subtype classification, treatment response assessment, outcome prediction, and monitoring of measurable residual disease. We finally discuss how ctDNA could be implemented in prospective clinical trials as a novel surrogate endpoint and be utilized as a decision-making tool to guide lymphoma treatment in the future.

Abstract
Treatment with high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is considered standard of care (SOC) second-line treatment for relapsed or refractory large B-cell lymphoma (LBCL). However, outcomes remain suboptimal. A systematic review and meta-analysis of randomised controlled trials comparing efficacy and safety of SOC versus chimeric antigen receptor T-cell (CAR-T) therapy as second-line for patients with LBCL refractory or relapsing within 12 months. Outcomes included overall survival (OS), event-free survival (EFS), overall response rate (ORR) and safety. Three trials published in 2021 (involving 865 participants) fulfilled the eligibility criteria. EFS as well as OS were significantly improved with CAR-T therapy as compared to SOC, hazard ratio (HR) 0.57 (95% confidence interval [CI] 0.49-0.68) and HR 0.77 (95% CI 0.60-0.98) respectively. CAR-T therapy was associated with significantly better ORR, relative risk (RR) 1.55 (95% CI 1.12-2.13, p = 0.001). The risk of Grade III/IV adverse event was comparable between the two arms, RR 1.03 (95% CI 0.93-1.14). In summary, CAR-T therapy has superior outcomes as compared to SOC in patients with LBCL refractory or relapsing within 12 months, without excess of toxicity. Longer follow-up is needed to confirm these results and determine the optimal sequencing of CAR-T therapy in the management of LBCL.

Abstract
Since 2017, 3 CD19-directed chimeric antigen receptor (CAR) T cell therapies-axicabtagene ciloleucel, tisagenlecleucel, and lisocabtagene maraleucel-have been approved for relapsed/refractory aggressive diffuse large B cell lymphoma after 2 lines of therapy. Recently, 3 prospective phase 3 randomized clinical trials were conducted to define the optimal second-line treatment by comparing each of the CAR T cell products to the current standard of care: ZUMA-7 for axicabtagene ciloleucel, BELINDA for tisagenlecleucel, and TRANSFORM for lisocabtagene maraleucel. These 3 studies, although largely addressing the same question, had different outcomes, with ZUMA-7 and TRANSFORM demonstrating significant improvement with CD19 CAR T cells in second-line therapy compared with standard of care but BELINDA not showing any benefit. The US Food and Drug Administration has now approved axicabtagene ciloleucel and lisocabtagene maraleucel for LBCL that is refractory to first-line chemoimmunotherapy or relapse occurring within 12 months of first-line chemoimmunotherapy. Following the reporting of these practice changing studies, here a group of experts convened by the American Society for Transplantation and Cellular Therapy provides a comprehensive review of the 3 studies, emphasizing potential differences, and shares perspectives on what these results mean to clinical practice in this new era of treatment of B cell lymphomas.

Abstract
Abstract
Chimeric antigen receptor T cells have revolutionized the treatment of hematological malignancies during the past five years, boasting impressive response rates and durable remissions for patients who previously had no viable options. In this review, we provide a brief historical overview of their development. We focus on the practical aspects of a patient’s journey through this treatment and the unique toxicities and current best practices to manage those. We then discuss the key registration trials that have led to approvals for the treatment of relapsed/refractory acute lymphoblastic leukemia (ALL), diffuse large B cell lymphoma (DLBCL), follicular lymphoma, mantle cell lymphoma (MCL), and multiple myeloma. Finally, we consider the future development and research directions of this cutting edge therapy.

Abstract
Axicabtagene ciloleucel (axi-cel) is an anti-CD19 chimeric antigen receptor (CAR) T cell therapy approved for relapsed/refractory large B cell lymphoma (LBCL) and has treatment with similar efficacy across conventional LBCL subtypes. Toward patient stratification, we assessed whether tumor immune contexture influenced clinical outcomes after axi-cel. We evaluated the tumor microenvironment (TME) of 135 pre-treatment and post-treatment tumor biopsies taken from 51 patients in the ZUMA-1 phase 2 trial. We uncovered dynamic patterns that occurred within 2 weeks after axi-cel. The biological associations among Immunoscore (quantification of tumor-infiltrating T cell density), Immunosign 21 (expression of pre-defined immune gene panel) and cell subsets were validated in three independent LBCL datasets. In the ZUMA-1 trial samples, clinical response and overall survival were associated with pre-treatment immune contexture as characterized by Immunoscore and Immunosign 21. Circulating CAR T cell levels were associated with post-treatment TME T cell exhaustion. TME enriched for chemokines (CCL5 and CCL22), γ-chain receptor cytokines (IL-15, IL-7 and IL-21) and interferon-regulated molecules were associated with T cell infiltration and markers of activity. Finally, high density of regulatory T cells in pre-treatment TME associated with reduced axi-cel–related neurologic toxicity. These findings advance the understanding of LBCL TME characteristics associated with clinical responses to anti-CD19 CAR T cell therapy and could foster biomarker development and treatment optimization for patients with LBCL. Analysis of tumor biopsies from the pivotal phase 1/2 ZUMA-1 trial identifies pre-treatment T cell–related characteristics that are associated with clinical response and neurologic toxicity after anti-CD19 CAR T cell therapy in patients with large B cell lymphoma.

Abstract
Hematological malignancies represent defying clinical conditions, with high levels of morbidity and mortality, particularly considering patients who manifest multiple refractory disease. Recently, chimeric antigen receptor (CAR)-T cell therapy has emerged as a potential treatment option for relapsed/refractory B cell malignancies, which have motivated Food and Drug Administration approval of a series of products based on this technique. The objective of this systematic review was to assess the efficacy and safety of CAR-T cell therapy for patients with hematological malignancies. A comprehensive literature search was conducted in the electronic databases (CENTRAL, Embase, LILACS and MEDLINE), clinical trials register platforms (Clinicaltrials.gov and WHO-ICTRP) and grey literature (OpenGrey). The Cochrane Handbook for Reviews of Interventions was used for developing the review and the PRISMA Statement for manuscript reporting. The protocol was prospectively published in PROSPERO database (CRD42020181047). After the selection process, seven RCTs were included, three of which with available outcome results. The available results are from studies assessing axicabtagene, lisocabtagene and tisagenlecleucel for patients with B cell lymphoma, and the certainty of evidence ranged from very low to low for survival and progression-related outcome and for safety outcomes. Additionally, four randomized controlled trials comparing CAR-T cell therapy to the standard treatment for various types of relapsed/refractory B cell non-Hodgkin lymphomas and multiple myeloma included in this systematic review still did not have available outcome data. The results of this review may be used to guide clinical practice but evidence concerning safety and efficacy of CAR-T Cell therapy for hematological malignancies is still immature to recommend its application outside of clinical trials or compassionate use context for advanced and terminal cases. It is expected the results of the referred comparative studies will provide further elements to subsidize broader application of this immunotherapy. This article is protected by copyright.

Abstract
Simple Summary Immunotherapy helps a person’s immune system to target tumor cells. Recent advances in cancer immunotherapy, including immune checkpoint inhibition, chimeric antigen receptor T-cell therapy and cancer vaccination, have changed the landscape of cancer treatment. These approaches have had profound success in certain cancer types but still fail in the majority of cases. This review will cover both successes and current challenges in cancer immunotherapy, as well as recent advances in the field of basic tumor immunology that will allow us to overcome resistance to existing treatments. Abstract Cancer immunotherapy has revolutionized the field of oncology in recent years. Harnessing the immune system to treat cancer has led to a large growth in the number of novel immunotherapeutic strategies, including immune checkpoint inhibition, chimeric antigen receptor T-cell therapy and cancer vaccination. In this review, we will discuss the current landscape of immuno-oncology research, with a focus on elements that influence immunotherapeutic outcomes. We will also highlight recent advances in basic aspects of tumor immunology, in particular, the role of the immunosuppressive cells within the tumor microenvironment in regulating antitumor immunity. Lastly, we will discuss how the understanding of basic tumor immunology can lead to the development of new immunotherapeutic strategies.

Full automation of total metabolic tumor volume from FDG-PET/CT in DLBCL for baseline risk assessments. Cancer Imaging 2022; 22:39. [PMID: 35962459 PMCID: PMC9373298 DOI: 10.1186/s40644-022-00476-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 07/17/2022] [Indexed: 11/21/2022] Open
Abstract
Background Current radiological assessments of 18fluorodeoxyglucose-positron emission tomography (FDG-PET) imaging data in diffuse large B-cell lymphoma (DLBCL) can be time consuming, do not yield real-time information regarding disease burden and organ involvement, and hinder the use of FDG-PET to potentially limit the reliance on invasive procedures (e.g. bone marrow biopsy) for risk assessment. Methods Our aim is to enable real-time assessment of imaging-based risk factors at a large scale and we propose a fully automatic artificial intelligence (AI)-based tool to rapidly extract FDG-PET imaging metrics in DLBCL. On availability of a scan, in combination with clinical data, our approach generates clinically informative risk scores with minimal resource requirements. Overall, 1268 patients with previously untreated DLBCL from the phase III GOYA trial (NCT01287741) were included in the analysis (training: n = 846; hold-out: n = 422). Results Our AI-based model comprising imaging and clinical variables yielded a tangible prognostic improvement compared to clinical models without imaging metrics. We observed a risk increase for progression-free survival (PFS) with hazard ratios [HR] of 1.87 (95% CI: 1.31–2.67) vs 1.38 (95% CI: 0.98–1.96) (C-index: 0.59 vs 0.55), and a risk increase for overall survival (OS) (HR: 2.16 (95% CI: 1.37–3.40) vs 1.40 (95% CI: 0.90–2.17); C-index: 0.59 vs 0.55). The combined model defined a high-risk population with 35% and 42% increased odds of a 4-year PFS and OS event, respectively, versus the International Prognostic Index components alone. The method also identified a subpopulation with a 2-year Central Nervous System (CNS)-relapse probability of 17.1%. Conclusion Our tool enables an enhanced risk stratification compared with IPI, and the results indicate that imaging can be used to improve the prediction of central nervous system relapse in DLBCL. These findings support integration of clinically informative AI-generated imaging metrics into clinical workflows to improve identification of high-risk DLBCL patients.

The impact of race, ethnicity, and obesity on CAR T-cell therapy outcomes. Blood Adv 2022; 6:6040-6050. [PMID: 35939781 PMCID: PMC9700270 DOI: 10.1182/bloodadvances.2022007676] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 07/25/2022] [Indexed: 12/14/2022] Open
Abstract
Cancer outcomes with chemotherapy are inferior in patients of minority racial/ethnic groups and those with obesity. Chimeric antigen receptor (CAR) T-cell therapy has transformed outcomes for relapsed/refractory hematologic malignancies, but whether its benefits extend commensurately to racial/ethnic minorities and patients with obesity is poorly understood. With a primary focus on patients with B-cell acute lymphoblastic leukemia (B-ALL), we retrospectively evaluated the impact of demographics and obesity on CAR T-cell therapy outcomes in adult and pediatric patients with hematologic malignancies treated with CAR T-cell therapy across 5 phase 1 clinical trials at the National Cancer Institute from 2012 to 2021. Among 139 B-ALL CAR T-cell infusions, 28.8% of patients were Hispanic, 3.6% were Black, and 29.5% were overweight/obese. No significant associations were found between race, ethnicity, or body mass index (BMI) and complete remission rates, neurotoxicity, or overall survival. Hispanic patients were more likely to experience severe cytokine release syndrome compared with White non-Hispanic patients even after adjusting for leukemia disease burden and age (odds ratio, 4.5; P = .001). A descriptive analysis of patients with multiple myeloma (n = 24) and non-Hodgkin lymphoma (n = 23) displayed a similar pattern to the B-ALL cohort. Our findings suggest CAR T-cell therapy may provide substantial benefit across a range of demographics characteristics, including for those populations who are at higher risk for chemotherapy resistance and relapse. However, toxicity profiles may vary. Therefore, efforts to improve access to CAR therapy for underrepresented populations and elucidate mechanisms of differential toxicity among demographic groups should be prioritized.

Assessing the role of radiotherapy in patients with refractory or relapsed high-grade B-cell lymphomas treated with CAR T-cell therapy. Radiother Oncol 2022; 175:65-72. [PMID: 35952976 DOI: 10.1016/j.radonc.2022.08.007] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2022] [Revised: 07/31/2022] [Accepted: 08/03/2022] [Indexed: 11/22/2022]
Abstract
An estimated 30-40% of patients with diffuse large B cell lymphoma (DLBCL) will either relapse or have refractory disease with first-line chemoimmunotherapy. The standard approach for relapsed/refractory disease is salvage chemotherapy followed by autologous stem cell transplantation, but this approach cures fewer than 20% of patients in the modern era. This low cure rate is a result of refractory disease despite salvage therapy, medical ineligibility for transplantation, or relapse following transplantation. CD19-targeted chimeric antigen receptor (CAR) T-cell therapy has revolutionized the treatment paradigm for patients with relapsed or refractory disease, leading to response rates that range between 52% to 93%, and overall survival rates at one year between 48% and 83%. However, the time from apheresis to infusion of CAR T-cell therapy currently takes several weeks, leaving many patients in need of bridging therapy to control disease progression. Radiation therapy (RT) has been utilized as a bridging therapy prior to CAR T infusion in select patients, with some remarkable responses in chemorefractory disease. Furthermore, the potential synergy between RT and CAR T-cells due to immunomodulatory mechanisms has generated considerable excitement, as it has been hypothesized that RT could also be considered as a salvage therapy following CAR T failure, based on limited case series published to date. Prospective trials are warranted to validate the significance of this modality following CAR T-cell therapy.
