Chimeric antigen receptor (CAR) T-cell therapy relies on T cells engineered to target specific tumor antigens such as CD-19 in B-cell malignancies. In this setting, the commercially available products have offered a potential long-term cure for both pediatric and adult patients. Yet manufacturing CAR T cells is a cumbersome, multistep process, the success of which strictly depends on the characteristics of the starting material, i.e., lymphocyte collection yield and composition. These, in turn, might be affected by patient factors such as age, performance status, comorbidities, and previous therapies. Ideally, CAR T-cell therapies are a one-off treatment; therefore, optimization and the possible standardization of the leukapheresis procedure is critical, also in view of the novel CAR T cells currently under investigation for hematological malignancies and solid tumors. The most recent Best Practice recommendations for the management of children and adults undergoing CAR T-cell therapy provide a comprehensive guide to their use. However, their application in local practice is not straightforward and some grey areas remain. An Italian Expert Panel of apheresis specialists and hematologists from the centers authorized to administer CAR T-cell therapy took part in a detailed discussion on the following: 1) pre-apheresis patient evaluation; 2) management of the leukapheresis procedure, also in special situations represented by low lymphocyte count, peripheral blastosis, pediatric population <25 kg, and the COVID-19 outbreak; and 3) release and cryopreservation of the apheresis unit. This article presents some of the important challenges that must be faced to optimize the leukapheresis procedure and offers suggestions as to how to improve it, some of which are specific to the Italian setting.

Multiple myeloma (MM) is the main indication for autologous stem cell transplantation (ASCT). Novel supportive therapies (e.g., granulocyte colony-stimulating factor) have significantly improved post-ASCT-related mortality; however, data on biosimilar pegfilgrastim-bmez (BIO/PEG) in this setting is lacking. This prospective cohort study compared Italian patients with MM who received BIO/PEG post-ASCT with data collected retrospectively from historical control groups from the same center who received either filgrastim-sndz (BIO/G-CSF) or pegfilgrastim (PEG; originator). The primary endpoint was time to neutrophil engraftment (three consecutive days with an absolute neutrophil count ≥ 0.5 × 10 9 /L). Secondary endpoints included incidence and duration of febrile neutropenia (FN). Of the 231 patients included, 73 were treated with PEG, 102 with BIO/G-CSF, and 56 with BIO/PEG. Median age was 60 years and 57.1% were male. Neutrophil engraftment was reached after a median of 10 days in the BIO/PEG and PEG groups and 11 days in the BIO/G-CSF group. Among patients who achieved neutrophil engraftment earlier than this (i.e., day 9), 58% (29/50) were on PEG; of those who achieved it later (i.e., day 11), 80.8% (59/73) were on BIO/G-CSF. FN incidence was higher with BIO/G-CSF (61.4%) versus PEG (52.1%) or BIO/PEG (37.5%) (p = 0.02 among groups). Patients on BIO/PEG had less frequent grade 2-3 diarrhea (5.5%) compared with BIO/G-CSF (22.5%) or PEG (21.9%); grade 2-3 mucositis was most frequent in the BIO/G-CSF group. In conclusion, pegfilgrastim and its biosimilar displayed an advantageous efficacy and safety profile compared with biosimilar filgrastim in patients with MM post-ASCT., (© 2023.

Purpose: CAR-T programs will burden increasingly on healthcare systems, since the implementation of these therapies involves: multidisciplinary team collaboration, post-infusion hospitalization with risk of life-threatening toxicities, frequent in hospital visits and prolonged follow-up which heavily influence patients' quality of life. In this review we propose an innovative, telehealth-based, model for monitoring CAR-T patients: this method was used for managing a case of COVID-19 infection occurred two weeks after CAR-T cell infusion., Methods: Several benefits for management of all these aspects of CAR-T programs could be made using telemedicine: for example, telemedicine real-time clinical monitoring could reduce the COVID-19 contagion risks for CAR-T patients., Results: Our experience confirmed feasibility and utility of this approach in a real-life case. We believe that use of telemedicine for CAR-T patients could improve: the logistics of toxicity monitoring (frequent vital sign checks and neurologic assessments), the multidisciplinary team communication (patient selection, specialists consulting, coordination with pharmacists, etc.), the decrease in hospitalization time and the reduction of ambulatory visits., Conclusions: This approach will be fundamental for future CAR-T cell program development, enhancing patients' quality of life and cost-effectiveness for healthcare systems., (© 2023.

Introduction: Chimeric antigen receptor (CAR)-T-cell therapy is a new treatment for patients with hematologic malignancies in which other therapies have failed., Areas Covered: The review provides an overview for recognizing and managing the most acute toxicities related to CAR-T cells., Expert Opinion: The development of immune-mediated toxicities is a common challenge of CAR-T therapy. The mechanism that determines this toxicity is still unclear, although an unfavorable tumor microenvironment and a pro-inflammatory state put patients at risk. The monitoring, diagnosis, and treatment of post-CAR-T toxicities must be determined and based on international guidelines and internal clinical practice. It is urgent to identify biomarkers that can identify patients at greater risk of developing complications. The adoption of consistent grading criteria is necessary to improve toxicity management strategies continually. The first-line therapy consists of supportive care and treatment with tocilizumab or corticosteroids. An early start of cytokine blockade therapies could mitigate toxicity. The plan will include cytokine release prophylaxis, a risk-adapted treatment, prevention of on-target/off-tumor effect, and a switch on/off CAR-T approach.

Chemotherapy-induced nausea and vomiting (CINV) is one of the most frequent adverse events compromising quality of life (QoL) in patients undergoing autologous stem cell transplantation (ASCT). However, CINV prophylaxis is still lacking uniformity for high-dose melphalan (HDM), which is used to condition patients with multiple myeloma (MM). Netupitant/palonosetron (NEPA) is administered with dexamethasone (DEXA) for CINV prevention in several chemotherapy regimens. Our study aims to assess the efficacy of NEPA, without DEXA, in preventing CINV in 106 adult patients with MM receiving HDM and ASCT. All patients had antiemetic prophylaxis with multiple doses of NEPA 1 h before the start of conditioning and after 72 h and 120 h. A complete response (CR) was observed in 99 (93%) patients at 120 h (overall phase). The percentage of patients with complete control was 93%. The CR rate during the acute phase was 94% (n = 100). During the delayed phase, the CR rate was 95% (n = 101). Grade 1 nausea and vomiting were experienced by 82% and 12% of the patients, respectively. Grade 2 nausea was reported in 18% and vomiting in 10% of patients. Our results showed, for the first time, that NEPA, without DEXA, was a well-tolerated and effective antiemetic option for MM patients receiving HDM followed by ASCT., (© 2021.

Despite the improvement in survival outcomes, multiple myeloma (MM) remains an incurable disease. Chimeric antigen receptor (CAR) T-cell therapy targeting B-cell maturation antigen (BCMA) represents a new strategy for the treatment of relapsed/refractory MM (R/R). In this paper, we describe several recent advances in the field of anti-BCMA CAR T-cell therapy and MM. Currently, available data on anti-BCMA CART-cell therapy has demonstrated efficacy and manageable toxicity in heavily pretreated R/R MM patients. Despite this, the main issues remain to be addressed. First of all, a significant proportion of patients eventually relapse. The potential strategy to prevent relapse includes sequential or combined infusion with CAR T-cells against targets other than BCMA, CAR T-cells with novel dual-targeting vector design, and BCMA expression upregulation. Another dark side of CART therapy is safety. Cytokine release syndrome (CRS) andneurologic toxicity are well-described adverse effects. In the MM trials, most CRS events tended to be grade 1 or 2, with fewer patients experiencing grade 3 or higher. Another critical point is the extended timeline of the manufacturing process. Allo-CARs offers the potential for scalable manufacturing for on-demand treatment with shorter waiting days. Another issue is undoubtedly going to be access to this therapy. Currently, only a few academic centers can perform these procedures. Recognizing these issues, the excellent response with BCMA-targeted CAR T-cell therapy makes it a treatment strategy of great promise.

Purpose: Cyclophosphamide (CY) in a dose of 2-4 g/m 2 is widely used for hemopoietic progenitor stem cells mobilization. CY administration is associated with several adverse effects, including chemotherapy-induced nausea and vomiting (CINV). This study aimed to evaluate the efficacy and tolerability of granisetron transdermal system (GTDS) plus dexamethasone in the management of CINV in MM patients undergoing chemo-mobilization with CY., Methods: In this single-center, prospective, observational, real world study, GTDS plus dexamethasone was administered to MM patients receiving chemo-mobilization based on CY 2 g/m2 plus G-CSF in an outpatient setting. The rate of complete response was evaluated as the main outcome. Other outcomes were rate of complete control of CINV, incidence of nausea/vomiting of any grade and safety., Results: A total of 88 patients were enrolled. A complete response was achieved in 45.5 % of patients; among them, 39.77 % attained complete control of CINV. Nausea and vomiting never occurred in 34.1 % and 45.5 % of patients, respectively. No episodes of grade 3-4 nausea and/or vomiting were documented. GTDS was safe and well tolerated., Conclusion: In real world, GTDS provided an innovative, effective, and well-tolerated control of CINV in MM patients after chemo-mobilization with CY. The study found out effectiveness of a non-invasive delivery system of antiemetic., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

G-CSF administration after high-dose chemotherapy and autologous stem cell transplantation (ASCT) has been shown to expedite neutrophil recovery. Several studies comparing filgrastim and pegfilgrastim in the post-ASCT setting concluded that the two are at least equally effective. Lipegfilgrastim (LIP) is a new long-acting, once-per-cycle G-CSF. This multicentric, prospective study aimed to describe the use of LIP in multiple myeloma patients receiving high-dose melphalan and autologous stem cell transplantation (ASCT) and compare LIP with historic controls of patients who received short-acting agent (filgrastim [FIL]). Overall, 125 patients with a median age of 60 years received G-CSF after ASCT (80 patients LIP on day 1 post-ASCT and 45 patients FIL on day 5 post-ASCT). The median duration of grade 4 neutropenia (absolute neutrophil count [ANC] < 0.5 × 10 [9]/L) was 5 days in both LIP and FIL groups, whereas the median number of days to reach ANC ≥ 0.5 × 10 [9]/L was 10% lower in the LIP than in the FIL group (10 vs 11 days), respectively. Male sex was significantly associated with a faster ANC ≥ 0.5 × 10 [9] L response (p = 0.015). The incidence of FN was significantly lower in the LIP than in the FIL group (29% vs 49%, respectively, p = 0.024). The days to discharge after ASCT infusion were greater in patients with FN (p < 0.001). The study indicates that LIP had a shorter time to ANC recovery and is more effective than FIL for the prevention of FN in the ASCT setting.

A longitudinal, prospective, observational, single-center cohort study on healthy donors was designed to identify predictors of CD34 + cell mobilization on day 4 after granulocyte colony-stimulating factor (G-CSF) administration. As potential predictors of mobilization, age, sex, body weight, height, blood volume, WBC count, peripheral blood (PB) mononuclear cell count, platelet (Plt) count, and hematocrit and hemoglobin levels were considered. Two different evaluations of CD34 + cell counts were determined for each donor: baseline (before G-CSF administration) and in PB on day 4 after G-CSF administration. One hundred twenty-two consecutive healthy donors with a median age of 47.5 years were enrolled. The median value of CD34 + on day 4 was 43 cells/µL (interquartile range, 23 to 68), and 81.1% of donors had ≥20 cells/µL. Basal WBC count, Plt count, and CD34 + were significantly higher for the subjects with CD34 + levels over median values on day 4. A multivariate quartile regression analysis, adjusted by sex, age, basal CD34 + , and basal Plt count, showed a progressively stronger relationship between baseline CD34 + and Plt levels and the CD34 + levels on day 4. The basal CD34 + cut-off level to predict the levels of CD34 + on day 4 was either ≤2 cells/μL or ≥3 cells/μL and that of basal Plt count was ≤229 × 10 9 /L or ≥230 × 10 9 /L, respectively, to determine whether mobilization therapy should or should not be attempted. PB stem cell mobilization with G-CSF was highly effective on day 4, and herein we describe a model for predicting the probability of performing PB stem cell collection after a short course of G-CSF., (Copyright © 2019 American Society for Blood and Marrow Transplantation.

Introduction : Management of multiple myeloma (MM) has improved over recent years. Health-related quality of life (HRQoL) data is becoming increasingly important, owing to improved survival outcomes. Areas covered : The authors performed an expert review of the literature to identify evidence-based data available on HRQoL in frontline and relapsed/refractory MM (RRMM) patients. Expert opinion : De-novo patients should be informed that the HRQoL is expected to improve during first-line treatment with different degrees of possible deterioration during the first cycles. Achievement of a maximal response should be strongly considered, particularly in the frontline setting, but must also be balanced with tolerability, HRQoL, and patient preferences. The same degree of improvement in HRQoL cannot be expected during conventional relapse treatments, where patients should be prepared only for stabilization of HRQoL. However, focusing attention only on measures such as toxicity may provide just a partial view of overall treatment effectiveness. Nonetheless, the authors believe the added value of taking into consideration the patient's perspectives and the importance of patient-reported outcomes in the evaluation of treatment effects should be considered mandatory. The incorporation of quality of life assessment into clinical and research practice has the potential of improving treatment outcomes.

Predicting mobilization failure before it starts may enable patient-tailored strategies. Although consensus criteria for predicted PM (pPM) are available, their predictive performance has never been measured on real data. We retrospectively collected and analyzed 1318 mobilization procedures performed for MM and lymphoma patients in the plerixafor era. In our sample, 180/1318 (13.7%) were PM. The score resulting from published pPM criteria had sufficient performance for predicting PM, as measured by AUC (0.67, 95%CI: 0.63-0.72). We developed a new prediction model from multivariate analysis whose score (pPM-score) resulted in better AUC (0.80, 95%CI: 0.76-0.84, p < 0001). pPM-score included as risk factors: increasing age, diagnosis of NHL, positive bone marrow biopsy or cytopenias before mobilization, previous mobilization failure, priming strategy with G-CSF alone, or without upfront plerixafor. A simplified version of pPM-score was categorized using a cut-off to maximize positive likelihood ratio (15.7, 95%CI: 9.9-24.8); specificity was 98% (95%CI: 97-98.7%), sensitivity 31.7% (95%CI: 24.9-39%); positive predictive value in our sample was 71.3% (95%CI: 60-80.8%). Simplified pPM-score can "rule in" patients at very high risk for PM before starting mobilization, allowing changes in clinical management, such as choice of alternative priming strategies, to avoid highly likely mobilization failure.

Outpatient autologous stem cell transplantation (ASCT) has proven to be feasible in terms of physical morbidity and mortality outcomes, but little data exist on the impact of this procedure on quality of life (QoL). The purpose of this prospective, observational, longitudinal cohort study was to compare the effects of inpatient (n = 76) and outpatient (n = 64) modes of care on QoL in patients with multiple myeloma who underwent ASCT. Patients were treated according to their preference for the inpatient or outpatient model. QoL was assessed using the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation (FACT-BMT) at baseline (7 days before ASCT; T1) and at days +7 (T2) and +30 (T3) after ASCT. Overall, inpatients achieved higher mean values at each time point (86.05 ± 15.54 at T1, 89.23 ± 19.19 at T2, and 87.96 ± 13.6 at T3) compared with outpatients (85.62 ± 14.51 at T1, 87.42 ± 23.41 at T2, and 83.98 ± 20.2 at T3), although the differences did not reach statistical significance. Inpatients showed higher mean scores than outpatients in physical well-being (7.67 ± 5.7, 15.44 ± 6.34, and 12.96 ± 6.03, respectively, versus 5.89 ± 4.33, 13.92 ± 7.05, and 8.84 ± 6.33, respectively; P < .05). Mean scores on social/family well-being were significantly higher in the outpatient group compared with the inpatient group (22.93 ± 13.29, 21.14 ± 5.31, and 21.64 ± 4.58, respectively, versus 20.59 ± 3.79, 19.52 ± 5.12, and 20.01 ± 3.97, respectively; P = .003). There were no significant between-group differences with respect to functional well-being and emotional status. Among adults at a single institution undergoing ASCT for MM, the use of outpatient care compared with standard transplantation care did not result in improved QoL during transplantation. Further research is needed for replication and to assess longer-term outcomes and implications., (Copyright © 2017 The American Society for Blood and Marrow Transplantation.

Background: Activity-based costing (ABC) was developed and advocated as a means of overcoming the systematic distortions of traditional cost accounting., Materials and Methods: We calculated the cost of high-dose chemotherapy and autologous stem cell transplantation (ASCT) in patients with multiple myeloma using the ABC method, through 2 different care models: the total inpatient model (TIM) and the early-discharge outpatient model (EDOM) and compared this with the approved diagnosis related-groups (DRG) Italian tariffs., Results: The TIM and EDOM models involved a total cost of €28,615.15 and €16,499.43, respectively. In the TIM model, the phase with the greatest economic impact was the posttransplant (recovery and hematologic engraftment) with 36.4% of the total cost, whereas in the EDOM model, the phase with the greatest economic impact was the pretransplant (chemo-mobilization, apheresis procedure, cryopreservation, and storage) phase, with 60.4% of total expenses. In an analysis of each episode, the TIM model comprised a higher absorption than the EDOM. In particular, the posttransplant represented 36.4% of the total costs in the TIM and 17.7% in EDOM model, respectively. The estimated reduction in cost per patient using an EDOM model was over €12,115.72. The repayment of the DRG in Calabrian Region for the ASCT procedure is €59,806. Given the real cost of the transplant, the estimated cost saving per patient is €31,190.85 in the TIM model and €43,306.57 in the EDOM model., Conclusion: In conclusion, the actual repayment of the DRG does not correspond to the real cost of the ASCT procedure in Italy. Moreover, using the EDOM, the cost of ASCT is approximately the half of the TIM model., (Copyright © 2017 Elsevier Inc. All rights reserved.)

A longitudinal, prospective, observational, single-center, cohort study on healthy donors (HDs) was designed to identify predictors of CD34 + cells on day 5 with emphasis on the predictive value of the basal CD34 + cell count. As potential predictors of mobilization, age, sex, body weight, height, blood volume as well as white blood cell count, peripheral blood (PB) mononuclear cells, platelet count, hematocrit, and hemoglobin levels were considered. Two different evaluations of CD34 + cell counts were determined for each donor: baseline (before granulocyte colony-stimulating factor [G-CSF] administration) and in PB after G-CSF administration on the morning of the fifth day (day 5). A total of 128 consecutive HDs (66 males) with a median age of 43 years were enrolled. CD34 + levels on day 5 displayed a non-normal distribution, with a median value of 75.5 cells/µL. To account for the non-normal distribution of the dependent variable, a quantile regression analysis to predict CD34 + on day 5 using the baseline value of CD34 + as the key predictor was performed. On crude analysis, a baseline value of CD34 + ranging from .5 cells/µL to 1 cells/µL predicts a median value of 50 cells/µL on day 5; a value of 2 cells/µL predicts a median value of 70.7 cells/µL; a value of 3 cells/µL to 4 cells/µL predicts a median value of 91.3 cells/µL, and a value ≥ 5 predicts a median value of 112 cells/µL. In conclusion, the baseline PB CD34 + cell count correlates with the effectiveness of allogeneic PB stem cell mobilization and could be useful to plan the collection., (Copyright © 2017 The American Society for Blood and Marrow Transplantation.

High-dose chemotherapy (HDT) with autologous stem cell transplantation is the standard of care for relapsed/refractory (RR) Hodgkin lymphoma (HL). Given that HDT may cure a sizeable proportion of patients refractory to first salvage, development of newer conditioning regimens remains a priority. We present the results of a novel HDT regimen in which carmustine was substituted by a third-generation chloroethylnitrosourea, fotemustine, with improved pharmacokinetics and safety (FEAM; fotemustine, etoposide, cytarabine, melphalan) in 122 patients with RR-HL accrued into a prospective registry-based study. Application of FEAM resulted in a 2-year progression-free survival (PFS) of 73·8% [95% confidence interval (CI), 0·64-0·81] with median PFS, overall survival and time to progression yet to be reached. The 2-year risk of progression adjusted for the competitive risk of death was 19·4% (95% CI, 0·12-0·27) for the entire patient population. Most previously established independent risk factors, except for fluorodeoxyglucose ((18) (F) FDG)-uptake, were unable to predict for disease progression and survival after FEAM. Although 32% of patients had (18) (F) FDG-positrin emission tomography-positive lesions before HDT, the 2-year risk of progression adjusted for competitive risk of death was 19·4% (95% CI; 0·12-0·27). No unusual acute toxicities or early/late pulmonary adverse events were registered. FEAM emerges as an ideal HDT regimen for RR-HL patients typically pre-exposed to lung-damaging treatments., (© 2015 John Wiley & Sons Ltd.)
