Telehealth-aided outpatient management of acute heart failure in a specialist virtual ward compared with standard care.

AIMS: The aim of this propensity score matched cohort study was to assess the outcomes of telehealth-guided outpatient management of acute heart failure (HF) in our virtual ward (HFVW) compared with hospitalized acute HF patients. METHODS AND RESULTS: This cohort study (May 2022-October 2023) assessed outcomes of telehealth-guided outpatient acute HF management using bolus intravenous furosemide in a HF-specialist VW. Propensity score matching (PSM) was performed using logistic regression to adjust for potential differences in baseline patient characteristics between HFVW and standard care [Get With The Guidelines-HF score, clinical frailty score (CFS), Charlson co-morbidity index (CCI), NT-proBNP, and ejection fraction]. Clinical outcomes (re-hospitalizations and mortality) were compared at 1, 3, 6, and 12 months versus standard care-SC (acute HF patients managed without telehealth in 2021). Five hundred fifty-four HFVW ADHF patients (age 73.1 ± 10.9 years; 46% female) were compared with 404 ADHF patients (74.2 ± 11.8; P = 0.15 and 49% female) in the standard care-SC cohort. After propensity score matching for baseline patient characteristics, re-hospitalizations were significantly lower in the HFVW compared with SC (1 month-HFVW 8.6% vs. SC-21.5%, P < 0.001; 3 months-21% vs. 30%, P = 0.003; 6 months-28% vs 41%, P < 0.001 and 12 months-47% vs. 57%, P = 0.005) and mortality was also lower at 1 month (5% vs. 13.7%; P < 0.001), 3 months (9.5% vs. 15%; P = 0.001), 6 months (15% vs. 21%; P = 0.03), and 12 months (20% vs. 26%; P = 0.04). Multivariate logistic regression analysis showed that compared with standard care, HFVW management was associated with lower odds of readmission (1-month odds ratio (OR) = 0.3 [95% Confidence Interval CI 0.2-0.5], P < 0.0001; 3 month OR = 0.15 [0.1-0.3], P < 0.0001; 6-month OR = 0.35 [0.2-0.6], P = 0.0002; 12-month OR = 0.25 [0.15-0.4], P ≤ 0.001 and mortality (1-month OR = 0.26 [0.14-0.48], P < 0.0001; 3-month OR = 0.11 [0.04-0.27], P < 0.0001; 6-month OR = 0.35, [0.2; 0.61], P = 0.0002; 12-month OR = 0.6 [0.48; 0.73], P = 0.03. Higher GWTG-HF score independently predicted increased odds of re-hospitalization (1-month OR = 1.2 [1.1-1.3], P < 0.001; 3-month OR = 1.5 [1.37; 1.64], P < 0.0001; 6-month OR = 1.3 [1.2-1.4], P < 0.0001; 12-month OR = 1.1 [1.05-1.2], P = 0.03) as well as mortality (1-month OR = 1.21 [1.1-1.3], P < 0.0001; 3-month OR = 1.3 [1.2-1.4], P < 0.0001; 6-month OR = 1.2 [1.1-1.3], P < 0.0001; 12-month OR = 1.3 [1.1-1.7], P = 0.02). Similarly higher CFS also independently predicted increased odds of re-hospitalizations (1-month OR = 1.9 [1.5-2.4], P < 0.0001; 3-month OR = 1.8 [1.3-2.4], P = 0.0003; 6-month OR = 1.4 [1.1-1.8], P = 0.015; 12-month OR 1.9 [1.2-3], P = 0.01]) and mortality (1-month OR = 2.1 [1.6-2.8], P < 0.0001; 3-month OR = 1.8 [1.2-2.6], P = 0.006; 6-month OR = 2.34 [1.51-5.6], P = 0.0001; 12-month OR = 2.6 [1.6-7], P = 0.02). Increased daily step count while on HFVW independently predicted reduced odds of re-hospitalizations (1-month OR = 0.85[0.7-0.9], P = 0.005), 3-month OR = 0.95 [0.93-0.98], P = 0.003 and 1-month mortality (OR = 0.85 [0.7-0.95], P = 0.01), whereas CCI predicted adverse 12-month outcomes (OR = 1.2 [1.1-1.4], P = 0.03). CONCLUSIONS: Telehealth-guided specialist HFVW management for ADHF may offer a safe and efficacious alternative to hospitalization in suitable patients. Daily step count in HFVW can help predict risk of short-term adverse clinical outcomes.

Cilta-cel, a BCMA-targeting CAR-T therapy for patients with multiple myeloma.

INTRODUCTION: Ciltacabtagene autoleucel (cilta-cel), a BCMA-targeting CAR-T therapy, is approved in the United States and Europe for patients with relapsed/refractory multiple myeloma (RRMM) and ≥1 prior line of therapy (LOT), including a proteasome inhibitor and an immunomodulatory drug, and are lenalidomide refractory. AREAS COVERED: We examine recent long-term data in heavily pretreated RRMM (LEGEND-2, CARTITUDE-1) and earlier LOTs (CARTITUDE-4) compared with standard therapy and discuss the rationale for investigating cilta-cel as frontline therapy for transplant-eligible and transplant-ineligible patients (CARTITUDE-5, CARTITUDE-6). EXPERT OPINION: CAR-T therapies can improve outcomes for patients with MM across different LOTs. CARTITUDE-1 and CARTITUDE-4 have set a new bar for efficacy, with median PFS of 34.9 months in heavily pretreated patients (CARTITUDE-1) and a 74% relative risk reduction for progression/death versus standard care in patients with 1-3 prior LOTs (CARTITUDE-4), with manageable safety. Response rates were consistent between the two studies: 98% in CARTITUDE-1 and approaching 100% for infused patients in CARTITUDE-4. Cilta-cel could be a key treatment choice for patients with RRMM after first LOT. Clinical trials investigating frontline cilta-cel therapy will provide valuable insights into optimizing treatment pathways with the aim to potentially cure MM.

The Value of History and Physical Examination to Optimize Outcomes of Cataract Surgery: A Systematic Review.

This systematic review was conducted to examine the value of the preoperative history and physical (H&P) examination and preoperative care prior to cataract extraction and the resulting outcomes of adverse events, patient experience, and cost. Four databases were searched using appropriate keywords from 2012 to 2022. Observational studies, randomized controlled trials, and quality improvement studies with data on the precataract H&P were included. Outcome measures were adverse events, cost, and patient experience. Of the 4,170 studies screened, 12 studies were included. Risk stratification of patients into a high-risk group with an H&P and a low-risk group without an H&P resulted in an increased incidence of minor adverse events in the low-risk group but did not increase the incidence of major adverse events or surgical adverse events. A short-term cost savings was reported, and patient experience was unchanged. In 2020, the Centers for Medicare and Medicaid Services removed the requirement for the precataract H&P within 30 days prior to ambulatory surgery, which has implications for surgery center policy. More research on the role of the preoperative H&P on patient experience, adverse events, cost, and outcomes should be conducted, given the methodological heterogeneity of this review.

Ciltacabtagene Autoleucel in Patients With Prior Allogeneic Stem Cell Transplant in the CARTITUDE-1 Study.

BACKGROUND: Patients with prior allogeneic stem cell transplant (alloSCT) are typically excluded from trials of chimeric antigen receptor (CAR) T cell therapies, because their engineered cells may include allogeneic T cells. Ciltacabtagene autoleucel (cilta-cel) demonstrated early, deep, durable responses and manageable safety in heavily pretreated relapsed/refractory multiple myeloma patients. We retrospectively analyzed patients who received alloSCT prior to cilta-cel in CARTITUDE-1. PATIENTS AND METHODS: Patients eligible for CARTITUDE-1 were ≥18 years, had ≥3 prior lines of therapy (LOT) or were double refractory to a proteasome inhibitor (PI) and immunomodulatory drug (IMiD) and had received a PI, IMiD, and anti-CD38 antibody. Patients with active graft-versus-host disease (GVHD) or had alloSCT within 6 months before apheresis were excluded. Patients received cilta-cel 5 to 7 days after lymphodepletion. RESULTS: Patients (N = 7) received median 9 prior LOTs (range, 6-14); median time since alloSCT was 5.1 years (range, 2.7-6.2). At median follow-up 27.7 months after cilta-cel infusion, overall response rate was 85.7% (n = 6). The safety profile was generally consistent with patients without alloSCT as prior therapy (cytokine release syndrome, 85.7% vs. 95.6%, respectively; immune effector cell-associated neurotoxicity syndrome, 14.3% vs. 16.7%). One patient with prior alloSCT had grade 3 movement and neurocognitive treatment-emergent adverse events/parkinsonism. No GVHD cases were reported. Two patients died due to adverse events (treatment-related lung abscess; unrelated liver failure). CONCLUSION: Cilta-cel efficacy and safety were comparable between CARTITUDE-1 patients with and without prior alloSCT. Additional studies are needed to fully elucidate the suitability of CAR-T cell therapy in the post-alloSCT setting.

Cilta-cel or Standard Care in Lenalidomide-Refractory Multiple Myeloma.

BACKGROUND: Ciltacabtagene autoleucel (cilta-cel), a B-cell maturation antigen (BCMA)-directed CAR T-cell therapy, is effective in heavily pretreated patients with relapsed or refractory multiple myeloma. We investigated cilta-cel in earlier treatment lines in patients with lenalidomide-refractory disease. METHODS: In this phase 3, randomized, open-label trial, we assigned patients with lenalidomide-refractory multiple myeloma to receive cilta-cel or the physician's choice of effective standard care. All the patients had received one to three previous lines of treatment. The primary outcome was progression-free survival. RESULTS: A total of 419 patients underwent randomization (208 to receive cilta-cel and 211 to receive standard care). At a median follow-up of 15.9 months (range, 0.1 to 27.3), the median progression-free survival was not reached in the cilta-cel group and was 11.8 months in the standard-care group (hazard ratio, 0.26; 95% confidence interval [CI], 0.18 to 0.38; P<0.001). Progression-free survival at 12 months was 75.9% (95% CI, 69.4 to 81.1) in the cilta-cel group and 48.6% (95% CI, 41.5 to 55.3) in the standard-care group. More patients in the cilta-cel group than in the standard-care group had an overall response (84.6% vs. 67.3%), a complete response or better (73.1% vs. 21.8%), and an absence of minimal residual disease (60.6% vs. 15.6%). Death from any cause was reported in 39 patients and 46 patients, respectively (hazard ratio, 0.78; 95% CI, 0.5 to 1.2). Most patients reported grade 3 or 4 adverse events during treatment. Among the 176 patients who received cilta-cel in the as-treated population, 134 (76.1%) had cytokine release syndrome (grade 3 or 4, 1.1%; no grade 5), 8 (4.5%) had immune effector cell-associated neurotoxicity syndrome (all grade 1 or 2), 1 had movement and neurocognitive symptoms (grade 1), 16 (9.1%) had cranial nerve palsy (grade 2, 8.0%; grade 3, 1.1%), and 5 (2.8%) had CAR-T-related peripheral neuropathy (grade 1 or 2, 2.3%; grade 3, 0.6%). CONCLUSIONS: A single cilta-cel infusion resulted in a lower risk of disease progression or death than standard care in lenalidomide-refractory patients with multiple myeloma who had received one to three previous therapies.

BCMA CAR-T induces complete and durable remission in refractory plasmablastic lymphoma.

Plasmablastic lymphoma (PBL) is a rare subtype of aggressive large B-cell lymphoma, with a dismal prognosis despite aggressive therapies. New approaches are needed for those with refractory disease. PBL expresses antigens similar to multiple myeloma (MM), including B-cell maturation antigen (BCMA). Chimeric antigen receptor T-cell (CAR-T) therapy directed against BCMA has shown efficacy for the treatment of heavily pretreated MM with low rates of grades 3 and 4 cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) in a phase Ib/II trial (A Study of JNJ-68284528, a CAR-T Directed Against BCMA in Participants With Relapsed or Refractory Multiple Myeloma (CARTITUDE-1), NCT03548207). However, data for the use of BCMA CAR-T for treating PBL are lacking.We report a challenging case of multiple refractory PBL that emerged from B-cell acute lymphoblastic leukemia in an adolescent who failed to respond to an allogeneic hematopoietic cell transplant. The patient developed rapidly advancing disease despite withdrawal of immunosuppression, treatment with etoposide, ibrutinib, and daratumumab, prompting consideration of BCMA CAR-T (under emergency investigational new drug (eIND)). The patient achieved a complete remission (CR), without recurrent acute graft versus host disease (GVHD), CRS or ICANS after BCMA CAR-T therapy. BCMA CAR-T expansion was detected in vivo, peaking on day 15. The patient remains in CR for more than a year post CAR-T therapy, supporting consideration of immunotherapy for future patients with refractory PBL, a disease with few treatment options.

Barriers and facilitators to nurses addressing social needs and associated outcomes in the ambulatory setting in adult patients: Systematic review.

AIM: To examine the barriers and facilitators nurses experience in addressing social needs in the United States and the associated outcomes of addressing these needs in adults in the ambulatory care setting. DESIGN: A systematic review with inductive thematic and narrative synthesis. DATA SOURCES: PubMed, CINAHL, Web of Science, and Embase from 2010 through 2021. REVIEW METHODS: Cochrane Handbook of Systematic Reviews; Risk of Bias-CASP and the JBI checklist; Certainty of evidence-GRADE-CERQual assessment. RESULTS: After duplicates were removed, 1331 titles and abstracts were screened, and a full-text review was performed on 189 studies. Twenty-two studies met inclusion criteria. The most frequently cited barriers to addressing social needs were lack of resources, workload burden, and lack of education in social needs. The most cited facilitators were engaging the person and family in decision-making, a well-integrated standardized data tracking and referral documentation system, clear communication within the clinic and with community partners, and specialized education and training. Seven studies measured the nurse's impact of screening for and addressing social needs, and outcomes improved in most of these studies. CONCLUSION: Barriers and facilitators specific to nurses in the ambulatory setting and associated outcomes were synthesized. Limited evidence suggests that screening for social needs by nurses may impact outcomes by decreasing hospitalizations, decreasing emergency department utilization, and improving self-efficacy towards medical and social services navigation. IMPACT: These findings inform practice and facilitate changes within nursing towards care that accounts for a person's individual social needs in ambulatory care settings and are most directly applicable to nurses and administrators in the United States. REPORTING METHOD: PRISMA guidelines, supplemented by the ENTREQ and SWiM guidelines. NO PATIENT OR PUBLIC CONTRIBUTION: This systematic review is the result of work performed by the four authors exclusively.

Component Costs of CAR-T Therapy in Addition to Treatment Acquisition Costs in Patients with Multiple Myeloma.

INTRODUCTION: Ciltacabtagene autoleucel (cilta-cel), is a B-cell maturation antigen-directed, genetically modified autologous chimeric antigen receptor T-cell (CAR-T) immunotherapy. It is indicated for treatment for adult patients with relapsed or refractory multiple myeloma (RRMM) after four or more prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. The objective of this study was to estimate the per-patient US commercial healthcare costs related to cilta-cel (CARVYKTI®) CAR-T therapy (i.e., costs separate from cilta-cel therapy acquisition) for patients with RRMM. METHODS: US prescribing information for cilta-cel, publicly available data, and published literature were used with clinician input to identify the cost components and unit costs associated with administration of cilta-cel. Cost components included apheresis, bridging therapy, conditioning therapy, administration, and postinfusion monitoring for 1 year of follow-up. Adverse event (AE) management costs for all grades of cytokine release syndrome and neurologic toxicities, and additional AEs grade ≥ 3 occurring in > 5% of patients were included in the analysis. RESULTS: The estimated per-patient average costs of cilta-cel CAR-T therapy administered exclusively in an inpatient setting, excluding cilta-cel therapy acquisition costs, totaled US$160,933 over a 12 month period. Costs assuming different proportions of inpatient/outpatient administration (85%/15% and 70%/30%) were US$158,095 and US$155,257, respectively. CONCLUSION: Cost estimates from this analysis, which disaggregates CAR-T therapy costs, provide a comprehensive view of the cost components of CAR-T therapy that can help healthcare decision-makers make informed choices regarding the use of cilta-cel. Real-world costs may differ with improved AE prevention and mitigation strategies.

Patient Perceptions Regarding Ciltacabtagene Autoleucel Treatment: Qualitative Evidence From Interviews With Patients With Relapsed/Refractory Multiple Myeloma in the CARTITUDE-1 Study.

INTRODUCTION: Ciltacabtagene autoleucel (cilta-cel), a novel chimeric antigen receptor T (CAR-T) cell therapy, has demonstrated early, deep, and durable clinical responses in heavily pretreated patients with relapsed/refractory multiple myeloma (RRMM), and improvements in health-related quality of life (HRQoL) in CARTITUDE-1 (NCT03548207). Patient perspectives on treatment provide context to efficacy outcomes and are an important aspect of therapeutic evaluation. METHODS: Qualitative interviews were conducted in a subset of CARTITUDE-1 patients (n = 36) at screening, Day 100, and Day 184 post cilta-cel on living with MM, therapy expectations, and treatment experiences during the study. RESULTS: Patients most wanted to see change in symptoms with the greatest impact on HRQoL: pain (85.2%) and fatigue (74.1%). The primary treatment expectation was achieving remission (40.7%), followed by extended life expectancy (14.8%). Patients most often defined meaningful change as improvement in symptoms (70.4%) and return to normalcy (40.7%). The percentage of patients reporting symptoms (pain, fatigue, bone fracture, gastrointestinal, neuropathy, and weakness) decreased from 85.2% to 22.2% across symptom types at baseline to 29.2% to 0% on Day 184 after cilta-cel. Improved symptoms and positive sentiments corresponded with improved perception of overall health status and reduced pain level, respectively. Most patients reported that their expectations of cilta-cel treatment had been met (70.8%) or exceeded (20.8%) at Day 184, and 70.8% of patients considered cilta-cel therapy better than their previous treatments. CONCLUSION: Overall HRQoL improvements and qualitative interviews showed cilta-cel met patient expectations of treatment and suggest the long treatment-free period also contributed to positive sentiments.

Ciltacabtagene Autoleucel, an Anti-B-cell Maturation Antigen Chimeric Antigen Receptor T-Cell Therapy, for Relapsed/Refractory Multiple Myeloma: CARTITUDE-1 2-Year Follow-Up.

PURPOSE: CARTITUDE-1, a phase Ib/II study evaluating the safety and efficacy of ciltacabtagene autoleucel (cilta-cel) in heavily pretreated patients with relapsed/refractory multiple myeloma, yielded early, deep, and durable responses at 12 months. Here, we present updated results 2 years after last patient in (median follow-up [MFU] approximately 28 months), including analyses of high-risk patient subgroups. METHODS: Eligible patients had relapsed/refractory multiple myeloma, had received ≥ 3 prior lines of therapy or were double refractory to a proteasome inhibitor and immunomodulatory drug and had received prior proteasome inhibitor, immunomodulatory drug, and anti-CD38 therapy. Patients received a single cilta-cel infusion 5-7 days after lymphodepletion. Responses were assessed by an independent review committee. RESULTS: At a MFU of 27.7 months (N = 97), the overall response rate was 97.9% (95% CI, 92.7 to 99.7); 82.5% (95% CI, 73.4 to 89.4) of patients achieved a stringent complete response. Median duration of response was not estimable. Median progression-free survival (PFS) and overall survival (OS) were not reached; 27-month PFS and OS rates were 54.9% (95% CI, 44.0 to 64.6) and 70.4% (95% CI, 60.1 to 78.6), respectively. Overall response rates were high across all subgroups (95.1%-100%). Duration of response, PFS, and/or OS were shorter in patients with high-risk cytogenetics, International Staging System stage III, high tumor burden, or plasmacytomas. The safety profile was manageable with no new cilta-cel-related cytokine release syndrome and one new case of parkinsonism (day 914 after cilta-cel) since the last report. CONCLUSION: At approximately 28 months MFU, patients treated with cilta-cel maintained deep and durable responses, observed in both standard and high-risk subgroups. The risk/benefit profile of cilta-cel remained favorable with longer follow-up.

Recent Advances in the Use of Chimeric Antigen Receptor-Expressing T-Cell Therapies for Treatment of Multiple Myeloma.

INTRODUCTION: Chimeric antigen receptor T cell (CAR-T) therapies have revolutionized the treatment paradigm for heavily pretreated B-cell malignancies such as large B-cell lymphoma. There is a major unmet need for effective treatments for heavily pretreated relapsed/refractory multiple myeloma (RRMM), for which many CAR-T therapies are under active clinical investigation. Goal of the review: This review provides an overview of recently updated clinical trial data and indirect treatment comparison analyses regarding two clinically advanced CAR-T therapies, idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel (cilta-cel). DISCUSSION: Recently presented data after prolonged follow-up periods for ide-cel (KarMMa) and cilta-cel (CARTITUDE-1) have demonstrated that both therapies have the potential to elicit responses in individuals with heavily pretreated RRMM. Indirect treatment comparisons between cilta-cel and ide-cel suggest cilta-cel is associated with deeper and more durable responses than ide-cel in triple class-exposed RRMM; however, these types of comparisons have limitations and direct head-to-head trials are needed to confirm these findings. Additional indirect treatment comparisons conducted separately for ide-cel and cilta-cel have demonstrated that these CAR-T therapies hold promise for substantial clinical benefit relative to currently available treatments for RRMM. Further considerations, including safety profiles and real-world treatment considerations, are also discussed. CONCLUSION: Data collected to date support CAR-T therapies holding substantial promise for patients with heavily pretreated RRMM relative to other currently available therapies. Additional real-world data will help provide further insights into the comparative efficacy and safety profiles of these treatments in RRMM as these treatments become more widely available.

Updated results from a matching-adjusted indirect comparison of efficacy outcomes for ciltacabtagene autoleucel in CARTITUDE-1 versus idecabtagene vicleucel in KarMMa for the treatment of patients with relapsed or refractory multiple myeloma.

OBJECTIVE: This study used the latest available data cuts from the CARTITUDE-1 and KarMMa clinical trials to update previously published matching-adjusted indirect treatment comparisons (MAICs) assessing the comparative efficacy of ciltacabtagene autoleucel (cilta-cel) versus the FDA-approved idecabtagene vicleucel (ide-cel) dose range of 300 to 450 × 106 CAR-positive T-cells in the treatment of patients with relapsed or refractory multiple myeloma (RRMM) who were previously treated with a proteasome inhibitor, an immunomodulatory drug, and an anti-CD38 monoclonal antibody (i.e. triple-class exposed). METHODS: MAICs were performed with the latest available individual patient data for cilta-cel (CARTITUDE-1) and published summary-level data for ide-cel (KarMMa). The analyses included treated patients from CARTITUDE-1 who satisfied the eligibility criteria for KarMMa. The MAIC adjusted for unbalanced baseline covariates of prognostic significance identified in the literature and by clinical expertise. Comparative efficacy was assessed for overall response rate (ORR), complete response or better (≥CR) rate, duration of response (DoR), progression-free survival (PFS), and overall survival (OS). RESULTS: Cilta-cel was associated with statistically significantly improved ORR (odds ratio [OR]: 94.93 [95% confidence interval [CI]: 21.86, 412.25; p < .0001]; relative risk [RR]: 1.34), ≥CR rate (OR: 5.65 [95% CI: 2.51, 12.69; p < .0001]; RR: 2.23), DoR (hazard ratio [HR]: 0.52 [95% CI: 0.30, 0.88; p = .0152]), PFS, (HR: 0.38 [95% CI: 0.24, 0.62; p < .0001]), and OS (HR: 0.43 [95% CI: 0.22, 0.88; p = .0200]) compared with ide-cel. CONCLUSIONS: These analyses demonstrate improved efficacy with cilta-cel versus ide-cel for all outcomes over longer follow-up and highlight its therapeutic potential in triple-class exposed RRMM patients.

Adjusted comparison of outcomes between patients from CARTITUDE-1 versus multiple myeloma patients with prior exposure to proteasome inhibitors, immunomodulatory drugs and anti-CD38 antibody from the prospective, multinational LocoMMotion study of real-world clinical practice.

Ciltacabtagene autoleucel (cilta-cel) is a chimeric antigen receptor T-cell therapy studied in patients with multiple myeloma exposed to three classes of treatment in the single-arm CARTITUDE-1 study. To assess the effectiveness of cilta-cel compared to real-world clinical practice (RWCP), we performed adjusted comparisons using individual patients' data from CARTITUDE-1 and LocoMMotion, a prospective, multinational study of patients with multiple myeloma triple-class exposed of treatment. Comparisons were performed using inverse probability weighting. In CARTITUDE-1, 113 patients were enrolled, and 97 patients were infused with cilta-cel. In LocoMMotion, 248 patients were enrolled, and 170 patients were included in the comparisons versus infused patients. Ninety-two unique regimens were used in LocoMMotion, most frequently carfilzomib-dexamethasone (13.7%), pomalidomide-cyclophosphamide-dexamethasone (13.3%) and pomalidomidedexamethasone (11.3%). Adjusted comparisons showed that patients treated with cilta-cel were 3.12-fold more likely to respond to treatment than those managed by RWCP (response rate, 3.12, 95% confidence interval [95% CI]: 2.24-4.00), had their risk of progression or death reduced to by 85% (progression-free survival hazard ratio=0.15, 95% CI: 0.08-0.29), and a risk of death lowered by 80% (overall survival hazard ratio HR=0.20, 95% CI: 0.09-0.41). The incremental improvement in healthrelated quality of life from baseline for cilta-cel versus RWCP at week 52, as measured by EORTC QLQ-C30 Global Health Status, was 13.4 (95% CI: 3.5-23.6) and increased to 30.8 (95% CI: 21.8-39.8) when including death as additional information regarding patients' health status. Patients treated with cilta-cel experienced more adverse events than those managed with RWCP (any grade: 100% vs. 83.5%). The results from this study demonstrate improved efficacy outcomes of cilta-cel versus RWCP and highlight its potential as a novel and effective treatment option for patients with multiple myeloma triple-class exposed of antimyeloma treatment. CARTITUDE-1 is registered with clinicaltrials gov. Identifier: NCT03548207. LocoMMotion is registered with clinicaltrials gov. Identifier: NCT04035226.

Health-related quality of life in patients given ciltacabtagene autoleucel for relapsed or refractory multiple myeloma (CARTITUDE-1): a phase 1b-2, open-label study.

BACKGROUND: CARTITUDE-1 is a phase 1b-2 study evaluating ciltacabtagene autoleucel (cilta-cel), a chimeric antigen receptor T cell therapy with two B-cell maturation antigen-targeting single-domain antibodies, in patients with relapsed or refractory multiple myeloma. Primary efficacy outcomes have previously been reported. Here, we report health-related quality of life (HRQOL) secondary outcomes evaluated using patient-reported outcomes. METHODS: This single-arm, open-label, phwase 1b-2 study was done at 16 centres in the USA. Patients were aged 18 years or older with diagnosis of multiple myeloma and Eastern Cooperative Oncology Group performance status of 1 or less with three or more previous lines of therapy, or were double refractory to a proteasome inhibitor and immunomodulatory drug, and had received a proteasome inhibitor, immunomodulatory drug, and anti-CD38 antibody. A single cilta-cel infusion (target dose 0·75 × 106 CAR+ T cells per kg) was administered 5-7 days after lymphodepletion. Patient-reported outcomes were assessed using the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaire core 30-item, pre-specified items from the EORTC myeloma module, and EuroQol five-dimensional descriptive system questionnaire. Clinically meaningful changes in patient-reported outcomes were defined by anchor-based minimally important differences. This trial is registered with ClinicalTrials.gov, NCT03548207. This trial is completed but feeding into a long-term follow-up study. FINDINGS: Between July 16, 2018, and Oct 7, 2019, 78 patients were enrolled and underwent apheresis in phase 2 of the study. 68 patients were treated (43 [63%] male, 49 [72%] White), and their patient-reported outcomes assessed (median follow-up 16·9 months, IQR 15·7-17·5). After infusion, a transient decline was observed, followed by improvements in global health status (mean change from baseline to day 464 +8·0 points, SD 20·9), physical (+4·6 points, 21·1), and emotional functional scales (+1·9 points, 23·7) over time, and declines for symptom-based scores (-14·1 pain, SD 31·5 and -15·4 fatigue; SD 29·5), indicating improved patient HRQOL following treatment with cilta-cel. INTERPRETATION: These durable HRQOL improvements are consistent with clinical findings, in which a single cilta-cel infusion led to substantial and durable responses in heavily pre-treated patients with relapsed or refractory multiple myeloma. These results support the use of cilta-cel in patients with relapsed or refractory multiple myeloma. FUNDING: Janssen Research & Development and Legend Biotech USA.

Population-based cellular kinetic characterization of ciltacabtagene autoleucel in subjects with relapsed or refractory multiple myeloma.

The aims of this work were to develop a population pharmacokinetic (PK) model for chimeric antigen receptor (CAR) transgene after single intravenous infusion administration of ciltacabtagene autoleucel in adult patients with relapsed or refractory multiple myeloma. CAR transgene level in blood were measured by quantitative polymerase chain reaction (qPCR) from 97 subjects in a phase Ib/II CARTITUDE-1 study (NCT03548207), with a targeted cilta-cel dose of 0.75 × 106 (range 0.5-1.0 × 106 ) CAR positive viable T-cells per kg body weight. The population PK model development was primarily guided by the current mechanistic understanding of CAR-T kinetics and the principles of building a parsimonious model. Cilta-cel PK was adequately described by a two-compartment model (with a fast and a slow apparent decline rate from each compartment, respectively) and a chain of four transit compartments with a lag time empirically representing the process from infused CAR-T cell to measurable CAR transgene. No apparent relationship was observed between cilta-cel dose (i.e., the actual number of CAR positive viable T-cells infused), given the narrow dose range, and the observed transgene level. Based on covariate search and subgroup analysis of maximum systemic CAR transgene level (Cmax ) and area under curve from the first dose to day 28 (AUC0-28d ), none of the investigated subjects' demographics, baseline characteristics, and manufactured product characteristics had significant effects on cilta-cel PK. The developed model is deemed robust and adequate for enabling subsequent exposure-safety and exposure-efficacy analyses.

Ciltacabtagene autoleucel in patients with relapsed/refractory multiple myeloma: CARTITUDE-1 (phase 2) Japanese cohort.

Chimeric antigen receptor (CAR) T cells targeting B-cell maturation antigen have shown positive responses in patients with multiple myeloma (MM). The phase 2 portion of the CARTITUDE-1 study of ciltacabtagene autoleucel (cilta-cel) included a cohort of Japanese patients with relapsed/refractory MM. Following a conditioning regimen of cyclophosphamide (300 mg/m2 ) and fludarabine (30 mg/m2 ), patients received a single cilta-cel infusion at a target dose of 0.75 × 106 (range, 0.5-1.0 × 106 CAR-positive viable T cells/kg). The primary endpoint was overall response rate (ORR; defined as partial response or better) by International Myeloma Working Group criteria. A key secondary endpoint was the rate of very good partial response (VGPR) or better (defined as VGPR, complete response, stringent complete response). This first analysis was performed at 6 months after the last patient received cilta-cel. Thirteen patients underwent apheresis, nine of whom received cilta-cel infusion. Eight patients who received cilta-cel at the target dose responded, yielding an ORR of 100%. Seven of eight (87.5%) patients achieved a VGPR or better. One additional patient who received a below-target dose of cilta-cel also achieved a best response of VGPR. MRD negativity (10-5 threshold) was achieved in all six evaluable patients. Eight of nine (88.9%) patients who received cilta-cel infusion experienced a grade 3 or 4 adverse event, and eight (88.9%) patients experienced cytokine release syndrome (all grade 1 or 2). No CAR-T cell neurotoxicity was reported. A positive benefit/risk profile for cilta-cel was established for heavily pretreated Japanese patients with relapsed or refractory MM.

Comparative effectiveness of ciltacabtagene autoleucel in CARTITUDE-1 versus physician's choice of therapy in the Flatiron Health multiple myeloma cohort registry for the treatment of patients with relapsed or refractory multiple myeloma.

Introduction: Ciltacabtagene autoleucel (cilta-cel) is a novel chimeric antigen receptor T-cell therapy that is being evaluated in the CARTITUDE-1 trial (NCT03548207) in patients with relapsed or refractory multiple myeloma (RRMM) who received as part of their previous therapy an immunomodulatory drug, proteasome inhibitor, and an anti-CD38 monoclonal antibody (i.e., triple-class exposed). Given the absence of a control arm in CARTITUDE-1, this study assessed the comparative effectiveness of cilta-cel and physician's choice of treatment (PCT) using an external real-world control arm from the Flatiron Health multiple myeloma cohort registry. Methods: Given the availability of individual patient data for cilta-cel from CARTITUDE-1 and PCT in Flatiron, inverse probability of treatment weighting was used to adjust for unbalanced baseline covariates of prognostic significance: refractory status, cytogenetic profile, International Staging System stage, time to progression on last regimen, number of prior lines of therapy, years since diagnosis, and age. Comparative effectiveness was estimated for progression-free survival (PFS), time to next treatment (TTNT), and overall survival (OS). A range of sensitivity analyses were conducted. Results: Baseline characteristics were similar between the two cohorts after propensity score weighting. Patients with cilta-cel had improved PFS (HR: 0.18 [95% CI: 0.12, 0.27; p < 0.0001]), TTNT (HR: 0.15 [95% CI: 0.09, 0.22; p < 0.0001]), and OS (HR: 0.25 [95% CI: 0.13, 0.46; p < 0.0001]) versus PCT. Cilta-cel treatment benefit was robust and consistent across all sensitivity analyses. Conclusion: Cilta-cel demonstrated significantly superior effectiveness over PCT for all outcomes, highlighting its potential as an effective therapy in patients with triple-class exposed RRMM.

Matching-Adjusted Indirect Treatment Comparison to Assess the Comparative Efficacy of Ciltacabtagene Autoleucel in CARTITUDE-1 Versus Belantamab Mafodotin in DREAMM-2, Selinexor-Dexamethasone in STORM Part 2, and Melphalan Flufenamide-Dexamethasone in HORIZON for the Treatment of Patients With Triple-Class Exposed Relapsed or Refractory Multiple Myeloma.

INTRODUCTION: This study estimated the comparative efficacy of ciltacabtagene autoleucel (cilta-cel; CARTITUDE-1), a chimeric antigen receptor (CAR)-T-cell therapy, versus 3 non-CAR-T therapies (belantamab mafodotin [DREAMM-2], selinexor plus dexamethasone [STORM Part 2], and melphalan flufenamide plus dexamethasone [HORIZON]), each with distinct mechanisms of action, for the treatment of patients with relapsed or refractory multiple myeloma (RRMM) who were triple-class exposed to an immunomodulatory drug, proteasome inhibitor, and an anti-CD38 monoclonal antibody. PATIENTS AND METHODS: Pairwise matching-adjusted indirect treatment comparisons (MAICs) were conducted using patient-level data for cilta-cel from CARTITUDE-1 and summary level data for each comparator (2.5 mg/kg cohort in DREAMM-2, modified intention-to-treat population in STORM Part 2, and triple-class refractory patients in HORIZON). Treated patients from CARTITUDE-1 who satisfied the eligibility of the comparator trial were included. MAICs adjusted for imbalances in important prognostic factors between CARTITUDE-1 and the comparator populations. Comparative efficacy of cilta-cel versus each therapy was estimated for overall response rate, complete response or better rate, progression-free survival, and overall survival. RESULTS: After adjustment, patients treated with cilta-cel demonstrated at least a 3.1-fold and at least a 10.3-fold increase in the likelihood of achieving an overall response or complete response or better, respectively, at least a 74% reduction in the risk of disease progression or death, and at least a 47% reduction in the risk of death. These results were statistically significant. CONCLUSION: Cilta-cel showed improved efficacy over each comparator for all outcomes, demonstrating its potential as an efficacious treatment for patients with triple-class exposed RRMM.

Process, resource and success factors associated with chimeric antigen receptor T-cell therapy for multiple myeloma.

Background: Chimeric antigen receptor T-cell (CAR-T) therapy represents a new frontier in multiple myeloma. It is important to understand critical success factors (CSFs) that may optimize its use in this therapeutic area. Methods: We estimated the CAR-T process using time-driven activity-based costing. Information was obtained through interviews at four US oncology centers and with payer representatives, and through publicly available data. Results: The CAR-T process comprises 13 steps which take 177 days; it was estimated to include 46 professionals and ten care settings. CSFs included proactive collaboration, streamlined reimbursement and CAR-T administration in alternative settings when possible. Implementing CSFs may reduce episode time and costs by 14.4 and 13.2%, respectively. Conclusion: Our research provides a blueprint for improving efficiencies in CAR-T therapy, thereby increasing its sustainability for multiple myeloma.

Patients with multiple myeloma can now be treated with chimeric antigen receptor T-cell (CAR-T) therapy. We studied how CAR-T therapy is used for multiple myeloma. We also studied things that could help make this therapy easier for doctors to use. The CAR-T process takes 13 steps and 177 days. It begins with the choice to use the therapy and ends about 100 days after it is used. The process uses 46 different healthcare professionals and ten different locations. We found several possible changes that can improve this process. Of these changes, three stand out. First, improved teamwork between members of the care team can help them prepare for and resolve possible problems. Second, reducing insurance red tape will make it easier to provide CAR-T therapy to patients. Third, allowing use of CAR-T therapy in places other than hospitals can help more patients receive this therapy. If applied, these three things may lower the time needed to treat patients by 14.4% and may reduce costs by 13.2%.
