We performed an international retrospective cohort study to investigate the prognostic impact of cytogenetic abnormalities by FISH in 283 patients with AL amyloidosis treated with frontline daratumumab-bortezomib-cyclophosphamide-dexamethasone (Dara-VCD) or Dara-VD. The cytogenetic subgroups of interest were t(11;14), gain/amp(1q) [hereafter, +1q], hyperdiploidy, deletion(13q), del(17p), and myeloma high-risk (HR) translocations (t[4;14], t[14;16], or t[14;20]). The endpoints of interest were rate of hematologic complete response (heme CR), very good partial response or better (≥VGPR), and hematologic event-free survival (Heme EFS). The incidence of abnormalities was following: t(11;14)-53.4%; deletion (13q)-28.9%; +1q-22.3%; hyperdiploidy-19.4%; HR translocations-6.6%; and deletion(17p)-4.5%. The heme-CR rate by cytogenetic subgroups were: t(11;14) vs no t(11;14)-45.2% vs 41.8% (p=0.597); del(13q) vs no del(13q)-46.8% vs 42.8% (p=0.594); +1q vs no +1q-30.2% vs 47.9% (p=0.022); hyperdiploidy vs no hyperdiploidy-39.5% vs 44.9% (p=0.541); HR translocations vs none: 45.5% vs 43.1% (p=0.877); and del(17p) vs no del(17p)-50.0% vs 42.9% respectively (p=0.658). Similarly, +1q was the only subgroup with a significantly lower ≥VGPR rate (64.2% vs 79.0%; p=0.033). At a median follow-up of 19.8 months, the median heme-EFS was 49.6 months (95% CI, 24.7-not reached [NR]), and the 2-year OS was 80.98% (95% CI, 75.6-85.4). The presence of+1q was significantly associated with worse heme-EFS on multivariate analysis (HR 2.06, 95% CI, 1.14-3.71; p=0.017). Notably, there was no adverse prognostic impact of t(11;14) on heme EFS or OS. In conclusion, +1q is associated with worse outcome in the daratumumab-era. Clinical trials testing novel immunotherapies frontline should be enriched in +1q to further improve outcomes in this subgroup.
RESUMEN
The Glasgow prognostic score (GPS) and CAR-HEMATOTOX (CAR-HT) score identify multiple myeloma (MM) patients at high risk for immune-mediated toxicity and early mortality with cellular immunotherapy. However, their association with outcomes in patients receiving T-cell redirecting bispecific antibodies (bsAb) is unclear. This multi-centre retrospective study examines the association of baseline GPS and CAR-HT scores with outcomes in 126 MM patients treated with bsAb. Overall, 19% were identified as GPS high risk but did not experience increased toxicity or mortality. Conversely, high-risk CAR-HT patients had a higher incidence of infections and inferior survival, suggesting a need for aggressive infection mitigation strategies.
RESUMEN
Immunoglobulin light chain (AL) amyloidosis is a malignant plasma cell dyscrasia causing multi-organ morbidity. High dose melphalan and autologous stem cell transplantation (ASCT) is a preferred consolidation approach and is safe with improved patient selection criteria. With the advent of bortezomib and daratumumab based induction therapy, nearly all patients can achieve deep hematological responses but follow up for daratumumab based induction is short. Consequently, the traditional approach of induction followed by ASCT is called into question. Given the multi-organ involvement of AL, endpoints beyond depth of response and hematological progression free survival (PFS) are important. Major organ dysfunction PFS (MOD-PFS) adds to PFS and is a composite endpoint of PFS, renal and cardiac organ progression, and overall survival. It is currently unknown which consolidative approach (ASCT or non-ASCT) will generate improved outcomes across the MOD-PFS spectrum a question the recently opened S2213 trial will attempt to answer.
RESUMEN
ABSTRACT: Recent studies demonstrating the feasibility of outpatient chimeric antigen receptor (CAR)-modified T-cell therapy administration are either restricted to CARs with 41BB costimulatory domains or use intensive at-home monitoring. We report outcomes of outpatient administration of all commercially available CD19- and B-cell maturation antigen (BCMA)-directed CAR T-cell therapy using a strategy of no remote at-home monitoring and an early cytokine release syndrome (CRS) intervention strategy. Patients with hematologic malignancies who received CAR T-cell therapy in the outpatient setting during 2022 to 2023 were included. Patients were seen daily in the cancer center day hospital for the first 7 to 10 days and then twice weekly through day 30. The primary end point was to determine 3-, 7-, and 30-day post-CAR T-cell infusion hospitalizations. Early CRS intervention involved administering tocilizumab as an outpatient for grade ≥1 CRS. Fifty-eight patients received outpatient CAR T-cell infusion (33 myeloma, 24 lymphoma, and 1 acute lymphoblastic leukemia). Of these, 17 (41%), 16 (38%), and 9 patients (21%) were admitted between days 0 to 3, 4 to 7, and 8 to 30 after CAR T-cell infusion, respectively. The most common reason for admission was CAR T-cell-related toxicities (33/42). Hospitalization was prevented in 15 of 35 patients who received tocilizumab for CRS as an outpatient. The nonrelapse mortality rates were 1.7% at 1 month and 3.4% at 6 months. In conclusion, we demonstrate that the administration of commercial CAR T-cell therapies in an outpatient setting is safe and feasible without intensive remote monitoring using an early CRS intervention strategy.

It is well-established that most patients with systemic light chain (AL) amyloidosis have multi-organ involvement and are often diagnosed after a lag period of increasing symptoms. We leverage electronic health record (EHR) data from the TriNetX research network to describe the incidence, timing, and co-occurrence of precursor conditions of interests in a cohort of AL amyloidosis patients identified between October 2015-December 2020. Nineteen precursor diagnoses of interest representing features of AL amyloidosis were identified using ICD codes up to 36 months prior to AL amyloidosis diagnosis. Among 1,401 patients with at least 36 months of EHR data prior to AL amyloidosis diagnosis, 46% were females, 16% were non-Hispanic Black, and 6% were Hispanic. The median age was 71 (range, 21-91) years. The median number of precursor diagnoses was 5 with dyspnea and fatigue being the most prevalent. The time from the first occurrence of a precursor to AL diagnosis ranged from 3.2 to 21.4 months. Analyses of pairwise co-occurrence of specific diagnoses indicated a high association (Cole's coefficient >0.6) among the examined precursor diagnoses. These findings provide novel information about the timing and co-occurrence of key precursor conditions and could be used to develop algorithms for early identification of AL amyloidosis.

Multiple myeloma (MM) is a heterogenous plasma cell malignancy, for which the established prognostic models exhibit limitations in capturing the full spectrum of outcome variability. Leveraging single-cell RNA-sequencing data, we developed a novel plasma cell gene signature. We evaluated and validated the associations of the resulting plasma cell malignancy (PBM) score with disease state, progression and clinical outcomes using data from five independent myeloma studies consisting of 2115 samples (1978 MM, 65 monoclonal gammopathy of undetermined significance, 35 smoldering MM, and 37 healthy controls). Overall, a higher PBM score was significantly associated with a more advanced stage within the spectrum of plasma cell dyscrasias (all p < 0.05) and a shorter overall survival in MM (hazard ratio, HR = 1.72; p < 0.001). Notably, the prognostic effect of the PBM score was independent of the International Staging System (ISS) and Revised ISS (R-ISS). The downstream analysis further linked higher PBM scores with the presence of cytogenetic abnormalities, TP53 mutations, and compositional changes in the myeloma tumor immune microenvironment. Our integrated analyses suggest the PBM score may provide an opportunity for refining risk stratification and guide decisions on therapeutic approaches to MM.

The objective of our study was to report real-world data on the safety and efficacy of standard-of-care teclistamab in patients with relapsed/refractory multiple myeloma (MM). This is a multi-institutional retrospective cohort study and included all consecutive patients that received at least one dose of teclistamab up until August 2023. One hundred and ten patients were included, of whom, 86% had triple-class refractory disease, 76% penta-refractory disease, and 35% had prior exposure to B-cell maturation antigen (BCMA)-targeting therapies. The overall response rate (ORR) in our cohort was 62%, with a ≥ very good partial remission (VGPR) rate of 51%. The ORR in patients with and without prior BCMA-targeted therapies was 54% vs 67%, respectively (p = 0.23). At a median follow-up of 3.5 months (range, 0.39-10.92), the estimated 3 month and 6 month progression free survival (PFS) was 57% (95% CI, 48%, 68%) and 52% (95% CI, 42%, 64%) respectively. The incidence of cytokine release syndrome (CRS) and immune effector cell associated neurotoxicity syndrome (ICANS) was 56% and 11% respectively, with grade ≥3 CRS and ICANS noted in 3.5% and 4.6% of patients respectively. 78 unique infections were diagnosed in 44 patients, with the incidence of all-grade and grade ≥3 infections being 40% vs 26% respectively. Primary prophylaxis with intravenous immunoglobulin (IVIG) was associated with a significantly lower infection risk on multivariate analysis (Hazard ratio [HR] 0.33; 95% CI 0.17, 0.64; p = 0.001).

OBJECTIVE: To evaluate the psychometric properties of the AL-PROfile, a patient-reported outcome measure combining the Patient-Reported Outcomes Measurement Information System (PROMIS)-29, two items from PROMIS Cognitive Function, and select Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) items. METHODS: Content validity was assessed through cognitive debriefing interviews of 20 patients who completed the AL-PROfile (Study 1). Study 2 involved 297 participants who completed the AL-PROfile and Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Reliability (internal consistency and test-retest reliability) and validity (convergent and discriminant validity, known groups validity by stage/organ involvement) were calculated. RESULTS: Study 1 participants found the AL-PROfile straightforward confirming the relevance of the included content. Some felt that certain questions were not related to their amyloidosis experience. Study 2 demonstrated acceptable internal consistency for all domains/items except PROMIS Cognitive Function and acceptable test-retest reliability for all except PROMIS Cognitive Function and PRO-CTCAE nausea. Large correlations were seen for the same domain across measures while correlations for divergent domains within a measure and different domains across different measures were small. The PRO-CTCAE items showed small to medium correlations with each other and with PROMIS and SF-36 domains. Stage was associated with physical function, fatigue, social roles, swelling, and shortness of breath scores. CONCLUSION: The AL-PROfile has acceptable reliability and validity for use in systemic light chain amyloidosis patients.

Autologous haematopoietic cell transplantation (autoHCT) and continuous post-transplant maintenance therapy are the standard of care in transplant-eligible multiple myeloma (MM) patients. We sought to describe symptom burden and identify symptom clusters occurring in MM patients after autoHCT using data from the BMT CTN 0702 randomized controlled trial comparing the outcomes of three treatment interventions after an autoHCT in 758 MM patients. We analysed individual transplant-related symptoms assessed via the FACT-BMT questionnaire at enrolment and annually for 4-year post-autoHCT. We also described the effect the individual symptoms and symptom clusters have on quality of life (QoL). We identified three stable symptom clusters: malaise symptom cluster (lack of energy, feeling ill, having pain, experiencing nausea, loss of appetite), physical symptom cluster (having skin problems, tremors, worsening eyesight, change in taste, shortness of breath, frequent colds) and emotional symptom cluster (feeling sad, being nervous, experiencing sleep problems). Malaise and emotional symptom clusters have a greater impact on QoL than the physical symptoms cluster. Identifying these symptoms warrant additional support in terms of psychosocial support, in addition to treatment of the physical symptoms themselves.

Persistent Immune Effector Cell Associated Hematotoxicity (ICAHT) is a significant side effect of BCMA CAR T-Cell therapy in patients with relapsed multiple myeloma (MM). The use of stem cell boosts in ICAHT has been described, however studies have been limited by small patient numbers and short follow up. Herein, we report on our multi-institutional experience of ICAHT, defined by an absolute neutrophil count (ANC) of ≤ 1000, thrombocytopenia with a platelet count ≤ 50,000 or/and anemia as hemoglobin (hgb) ≤9 g/dL, in patients who received BCMA CAR T therapy, and the effects of subsequent stem cell boost on hematopoietic reconstitution and clinical outcome. In this study, ICAHT was observed in 60% (n = 61/101) of patients at D + 21, and risk factors for its development included history of a prior ASCT, higher number of prior lines of therapy, a decreased platelet count prior to lymphodepletion and history of ICANS. 28% of patients with ICAHT received a stem cell boost at a median of 116 days due to profound and prolonged cytopenias often requiring ongoing transfusion support. Stem cell boost significantly improved cytopenias at 3 and 6 months follow up without any adverse effects on PFS and OS, underscoring the safety of this procedure.

The reduced risk of chronic graft-versus-host-disease (GVHD) with posttransplant cyclophosphamide (ptCy) in the setting of haploidentical related donor and more recently, with HLA-matched related and matched and mismatched unrelated donor allogeneic transplantation has been established. There is, however, paucity of data to show if ptCy impacts chronic GVHD pathogenesis, its phenotype and evolution after HCT regardless of the donor status. We examined the differences in chronic GVHD incidence and presentation in 314 consecutive patients after receiving their first allogeneic transplantation (HCT) using ptCy-based GVHD prophylaxis (ptCy-HCT; n = 120; including 95 with haploidentical related donor) versus conventional calcineurin inhibitor-based prophylaxis (CNI-MUD; n = 194) between 2012 and 2019. The 1-year cumulative incidence of all-grade chronic GVHD and moderate/severe chronic GVHD was 24% and 12%, respectively, after ptCy-HCT and 40% and 23% in the CNI-MUD recipients (p = 0.0003 and 0.007). Multivariable analysis confirmed that use of CNI-based GVHD prophylaxis and peripheral blood stem cell graft as the risk factors for chronic GVHD. The cumulative incidence of visceral (involving ≥1 of the following organs: liver, lungs, gastrointestinal tract, serous membranes) chronic GVHD was significantly higher with CNI-MUD vs. ptCy-HCT (27% vs. 15% at 1 year, p = 0.009). The incidence of moderate/severe visceral chronic GVHD was 20% in CNI-MUD group vs. 7.7% in the ptCy-HCT group at 1 year (p = 0.002). In addition, significantly fewer ptCy-HCT recipients developed severe chronic GVHD in ≥3 organs (0.8%) vs. 8.8% in the CNI-MUD group at 1-year posttransplant (p = 0.004). There was no significant different in relapse, non-relapse mortality, and relapse-free and overall survival between the two groups. Further investigation is needed to confirm that reduced risk and severity of chronic GVHD, less visceral organ distribution with ptCy-HCT leads to improved quality of life.

BACKGROUND: The Center for International Blood and Marrow Transplant Research (CIBMTR) provides a 1-year overall survival calculator to estimate outcomes for individual patients before they undergo allogeneic hematopoietic cell transplantation (HCT) to inform risk. The calculator considers pre-HCT clinical and demographic characteristics, but not patient-reported outcomes (PROs). Because pre-HCT PRO scores have been associated with post-HCT outcomes, the authors hypothesized that adding PRO scores to the calculator would enhance its predictive power. METHODS: Clinical data were obtained from the CIBMTR and the Blood and Marrow Transplant Clinical Trials Network. The PRO measures used were the 36-Item Short Form Survey (SF-36) and the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation. One thousand thirty-three adult patients were included. RESULTS: When adjusted for clinical characteristics, the SF-36 physical component score was significantly predictive of 1-year survival (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.81-0.95; p = .0015), whereas the mental component score was not (HR, 1.02; 95% CI, 0.95-1.10; p = 0.6396). The baseline single general health question on the SF-36 was also significantly associated with mortality (HR, 1.91 for those reporting fair/poor health vs. good, very good, or excellent health; 95% CI, 1.33-2.76; p = .0005). The addition of PRO scores to the calculator did not result in a significant change in the model's predictive ability. Self-reported pre-HCT scores were strongly predictive of self-reported health status (odds ratio, 3.35; 95% CI, 1.66-6.75; p = .0007) and quality of life (odds ratio, 3.24; 95% CI, 1.93-5.41; p < .0001) after HCT. CONCLUSIONS: The authors confirmed the significant, independent association of pre-HCT PRO scores with overall survival, although adding PRO scores to the survival calculator did not improve its performance. They also demonstrated that a single general health question was as accurate as the full measure for predicting survival, an important finding that may reduce respondent burden and promote its inclusion in routine clinical practice. Validation of these findings should be performed.
