Hematopoietic Stem Cell Transplant and Brain Volume Changes in Adults With Sickle Cell Disease

BACKGROUND AND OBJECTIVES: Adults with sickle cell disease (SCD) are at risk of decline in brain health and cognition, even without clinical stroke. SCD-related changes on MRI include brain atrophy and T2 fluid attenuated inversion recovery (FLAIR) white matter hyperintensity (WMH) growth. Hematopoietic stem cell transplant (HSCT) can be curative, but conditioning regimens risk new complications, particularly for adults with accumulated organ damage. We tested whether successful HSCT for adults with SCD was associated with reduced brain atrophy or WMH growth. METHODS: In this cohort study, adults with severe SCD underwent HSCT as part of 5 research protocols at the National Institutes of Health Clinical Center, including autologous gene therapy, HLA-matched donor HSCs, and haploidentical HSCs. Serial brain MRI scans acquired before and after transplant for up to 12 years included 3D T1-weighted and axial FLAIR sequences. Longitudinal brain volumes, segmented using FreeSurfer and corrected for total intracranial volume (TICV), were used to measure brain parenchymal fraction (BPF). A deep learning algorithm segmented WMH volumes from FLAIR sequences. Volumes were log2-transformed as a percentage of TICV. We tested whether HSCT success (persistent engraftment vs graft failure) or change in hemoglobin (Hb) (post-pre-HSCT) was associated with the rate of brain atrophy or WMH growth using mixed-effects linear regression. Random effects included scanner, participant intercept, and slope, while fixed effects included age and sex. RESULTS: Seventy-seven participants (mean age 32 ± 9 years, 43% female) who underwent HSCT were followed for a median 5.3 years (interquartile range [IQR] = 4.6). For 65 participants with successful HSCT, BPF declined nonsignificantly (-0.055%/year; 95% CI -0.12, 0.006; p = 0.08). Twelve participants with graft failure had a 7-fold greater BPF decline (-0.42%/year; 95% CI -0.57, -0.26; p < 0.001; group difference p < 0.001). A smaller change in Hb after HSCT was associated with steeper BPF decline (0.035%/year per unit Hb; 95% CI 0.017, 0.053; interaction p < 0.001). WMH growth was similar in both groups (0.038% vs 0.030% per year; interaction p = 0.50) and was associated with older age and baseline WMHs, but not treatment success. DISCUSSION: Successful HSCT was associated with preserved brain volume, but not WMH growth, another brain health biomarker. Whether these HSCT-related brain structural changes translate to cognitive preservation remains to be determined. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov NCT02140554 registered 2014-05-14, first enrollment February 2015; ClinicalTrials.gov NCT00061568; registered 2004-07-16, first enrollment July 2004; ClinicalTrials.gov NCT02105766; registered 2014-04-01, first enrollment April 2014; ClinicalTrials.gov NCT03077542; registered 2017-03-10, first enrollment April 2017; ClinicalTrials.gov NCT00977691; registered 2009-12-14, first enrollment December 2009. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that in adults with sickle cell disease, successful hematopoietic stem cell transplant is associated with slower declines in BPFs over a median period of 5 years, compared with patients with transplant failure.

A pilot randomized clinical trial of a peer support intervention for hematopoietic stem cell transplantation

Peer support has been associated with improved patient-reported outcomes (PROs), including reduced psychological distress, among patients undergoing hematopoietic stem cell transplantation (HSCT), but structured interventions are limited. This study assessed the feasibility, acceptability, and preliminary effects of a scalable peer support intervention to reduce psychological distress and enhance quality of life (QOL) post-HSCT. We conducted a pilot randomized clinical trial evaluating the Supporting Transplant Experiences with Peer Program (STEPP), a 5-session, telephone-based intervention delivered by an HSCT survivor offering psychoeducation and coping strategies. Participants were recruited 1 to 2 weeks pre-HSCT admission and randomized to STEPP or usual care. Feasibility was defined as ≥60% enrollment and ≥60% completing ≥3 sessions. Acceptability was assessed using the Client Satisfaction Questionnaire (CSQ; ≥3/4 mean benchmark). PRO measures of anxiety, depression (Hospital Anxiety and Depression Scale), posttraumatic stress (Post-Traumatic Stress Disorder Checklist-Civilian Version), QOL (Functional Assessment of Cancer Therapy-Bone Marrow Transplant), social support (Social Support and Effectiveness Questionnaire), and self-efficacy (Cancer Self-Efficacy Scale) were assessed pre-HSCT and at 30 and 60 days post-HSCT. Mixed-effects models explored preliminary effects. We enrolled 77% (90 of 117) of eligible patients (STEPP, n = 45; usual care, n = 45); 12 became ineligible due to HSCT cancellation or postponement. Among 78 active participants (mean age, 58.9 years [standard deviation, 12.3]; 57.7% women), all STEPP participants completed ≥3 sessions, and the mean CSQ score was 3.5. STEPP showed small-to-moderate improvements in day 30 anxiety (d = -0.36) and day 60 anxiety (d = -0.58), depression (d = -0.25), posttraumatic stress (d = -0.28), QOL (d = 0.48), social support (d = 0.36), and self-efficacy (d = 0.46). STEPP exceeds feasibility and acceptability thresholds, showing promising psychosocial benefits warranting a fully powered multisite efficacy trial. This trial was registered at www.clinicaltrials.gov as NCT06010017.

Pediatric-inspired regimens and HSCT for adolescents and young adults with acute lymphoblastic leukemia

The best frontline treatment for acute lymphoblastic leukemia (ALL) in adolescents and young adults (AYAs) is unclear. To support a clinical practice guideline, we systematically reviewed and meta-analyzed evidence on (1) asparaginase-based (pediatric) vs non-asparaginase-based (adult) regimens and (2) allogeneic hematopoietic stem cell transplantation (HSCT) vs no HSCT for AYAs (aged 15-39 years) with ALL in first complete remission. Data sources were PubMed, CINAHL, and PsycINFO from inception to 29 November 2023. Eligible studies compared regimens or the use of HSCT and reported survival, remission, toxicity, or quality of life in AYAs. We included 19 studies (14 comparative, 5 single-group; N = 3607) comparing regimens and 7 studies (N = 7492) comparing HSCT and no HSCT. Studies were mostly of poor quality, with sparse randomized controlled trials (RCTs), yielding low-certainty findings. Pediatric regimens were associated with higher 5-year overall survival (OS; relative risk [RR], 1.40; 95% confidence interval [CI], 1.18-1.65), event-free survival (RR, 1.80; 95% CI, 1.13-2.85), disease-free survival (DFS; RR, 1.55; 95% CI, 1.32-1.82), and lower treatment-related mortality (TRM; RR, 0.29; 95% CI, 0.09-0.90). HSCT was associated with lower 5-year OS (RR, 0.72; 95% CI, 0.61-0.84) and DFS (RR, 0.78; 95% CI, 0.68-0.90) and higher nonrelapse mortality (RR, 2.70; 95% CI, 1.18-6.18) and TRM (hazard ratio, 6.88; 95% CI, 3.02-15.70). Relapse risk varied by time point. In AYAs with Philadelphia chromosome-negative ALL, pediatric regimens may improve survival; toxicity-related evidence remains limited. HSCT may lead to inferior OS and DFS. With a dearth of RCTs, low-certainty evidence highlights the need for high-quality studies and subanalyses of AYAs.

A phase 1 trial of romidepsin, azacitidine, dexamethasone, and lenalidomide in relapsed or refractory T-cell lymphoma

Targeted therapies can induce responses in patients with relapsed/refractory T-cell lymphoma (R/R TCL) but are not curative. Genetic mutations associated with epigenetic and transcriptional dysregulation are common in many TCL subtypes, and drugs that modulate the epigenome and that target transcriptional regulators have synergistic activity in TCL. We hypothesized that fixed duration treatment with multiagent combinations of these drugs could produce deep responses leading to durable remissions. In a phase 1 trial, we tested escalating doses of lenalidomide added to romidepsin, azacitidine, and dexamethasone (RAdR) for patients with R/R TCL. The primary objective was to identify the maximum tolerated dose (MTD) of lenalidomide that could safely be used in RAdR. Secondary end points included response rate, survival, and markers of immune activation. Twenty-six patients enrolled and 21 were evaluable for response. Adverse events were predominantly gastrointestinal and hematologic. Grade 3/4 thrombocytopenia and neutropenia occurred in 19% and 21% of cycles, respectively. The MTD of lenalidomide was 20 mg. Among 9 patients treated at the MTD the objective response rate was 89% and complete response rate 22%. At 1 year, the estimated rate of progression-free survival was 14% and overall survival was 66%. Cell line models of anaplastic large cell lymphoma were interrogated to explore the activity of drug combinations in responding genetic subtypes. RAdR demonstrated activity in patients with highly refractory TCL but did not induce durable responses. This novel combination effectively bridged some patients with refractory TCL to consolidation such as allogeneic transplantation. This trial was registered at www.ClinicalTrials.gov as NCT04447027.

Addition of autologous stem-cell transplantation to an ibrutinib-containing first-line treatment in patients aged 18-65 years with mantle cell lymphoma (TRIANGLE): 4·5-year follow-up of a three-arm, randomised, open-label, phase 3 superiority trial of the European MCL Network

BACKGROUND: Adding ibrutinib to standard, first-line immunochemotherapy improves failure-free survival in adult patients aged 18-65 years with mantle cell lymphoma, according to the first results from the TRIANGLE trial. With prolonged follow-up, we investigated whether the addition of autologous stem-cell transplantation (ASCT) to an ibrutinib-containing regimen improves failure-free survival, and evaluated effects on overall survival. METHODS: We conducted a three-arm, randomised, open-label, phase 3 superiority trial (TRIANGLE) in 165 secondary or tertiary clinical centres, with experience in mantle cell lymphoma treatment and the capability to perform ASCT or an association with such a centre, in 13 European countries and Israel. Patients aged 18-65 years with untreated, stage II-IV mantle cell lymphoma and suitable for ASCT were randomly assigned (1:1:1) to control group A or experimental groups A + I or I. Randomisation was done using computer-generated random numbers and stratified by study groups and Mantle Cell Lymphoma International Prognostic Index risk groups. Treatment in group A consisted of six alternating, 21-day cycles of R-CHOP (intravenous rituximab 375 mg/m2 on day 0 or 1, cyclophosphamide 750 mg/m2 on day 1, doxorubicin 50 mg/m2 on day 1, vincristine 1·4 mg/m2 on day 1 [up to a maximum of 2 mg], and oral prednisone 100 mg on days 1-5) and R-DHAP or R-DHAOx (intravenous rituximab 375 mg/m2 on day 0 or 1, intravenous or oral dexamethasone 40 mg on days 1-4, high-dose intravenous cytarabine 2 × 2 g/m2 for 3 h every 12 h on day 2, plus either intravenous cisplatin 100 mg/m2 over 24 h on day 1 [R-DHAP] or intravenous oxaliplatin 130 mg/m2 on day 1 [R-DHAOx]), followed by ASCT. In group A + I, oral ibrutinib (560 mg daily) was added on days 1-19 of R-CHOP cycles and as 2-year maintenance after ASCT. In group I, ibrutinib was given the same way, but ASCT was omitted. Rituximab maintenance was allowed in all treatment groups according to national guidelines. Three pairwise, one-sided, log-rank tests for the primary outcome (failure-free survival) were statistically monitored. The primary analysis was by intention to treat and included all randomly assigned patients, ignoring protocol deviations. Safety was assessed in randomly assigned patients who started any trial treatment component of the respective treatment phase. The trial is registered with ClinicalTrials.gov (NCT02858258) and is complete. FINDINGS: Between July 29, 2016, and Dec 28, 2020, 870 patients (662 [76%] were male, 208 [24%] were female) were randomly assigned to group A (n=288), group A + I (n=292), or group I (n=290). After median follow-up of 54·9 months (95% CI 54·4-56·0), group A + I did not show superiority over group I, with 4-year failure-free survival of 82% (95% CI 78-87) versus 81% (76-86; hazard ratio [HR] 0·86 [one-sided 98·33% CI 0·00-1·27]; one-sided p=0·21). Group A + I remained superior to group A (82% [78-87] vs 70% [65-76]; HR 0·63 [one-sided 98·33% CI 0·00-0·89]; one-sided p=0·0026) and, as before, group A did not show superiority over group I (70% [65-76] vs 81% [76-86]; HR 1·45 [one-sided 98·33% CI 0·00-2·02]; one-sided p=0·99). 4-year overall survival was 88% (95% CI 84-92) in group A + I versus 81% (76-85) in group A (HR 0·59 [95% CI 0·38-0·92], p=0·0036) and 90% (87-94) in group I versus 81% (76-85) in group A (0·57 [0·36-0·90], p=0·0019). During maintenance or follow-up, the most common grade 3-5 adverse events were haematological disorders, reported in 127 (54%) of 234 patients in group A + I versus 74 (28%) of 269 in group I and 56 (23%) of 240 patients in group A, and infections, reported in 80 (34%) of 234 patients in group A + I versus 71 (26%) of 269 in group I and 37 (15%) of 240 patients in group A. Infections and infestations were the most common fatal adverse events during maintenance or follow-up, occurring in four (2%) of 234 patients in group A + I and five (2%) of 269 patients in group I. INTERPRETATION: After a prolonged follow-up of 55 months, both ibrutinib-containing groups showed relevant improvements not only in failure-free survival-a modified form of progression-free survival-but also in overall survival. In contrast, the addition of ASCT to an ibrutinib-containing regimen had no supplementary benefit but increased toxicity. Induction treatment with ibrutinib and R-CHOP plus R-DHAP (or R-DHAOx), followed by 2 years of maintenance treatment with ibrutinib, should be considered as a new standard of care for younger patients with mantle cell lymphoma.

First-in-Human Study of IL15-Activated Cytokine-Induced Killer Cells After Allogeneic HCT Shows Durable Remission and Serotherapy-Associated Immune Reconstitution in Leukemia

PURPOSE: Patients with high-risk (HR) leukemia remain at substantial risk of early relapse, treatment-related toxicity, and poor survival, underscoring the need for effective relapse prevention therapies. To our knowledge, this first-in-human, disease burden-guided study evaluated the feasibility, safety, and efficacy of donor-derived allogeneic interleukin-15-activated cytokine-induced killer cells (IL15-CIK) combining T-cell and natural killer cell properties for post-transplant disease control. METHODS: In a prospective, multicenter phase I/II trial (EudraCT 2013-005446-11) and an identically designed pilot study, 53 adult and pediatric patients with HR leukemia received 56 courses of IL15-CIK monotherapy after human leukocyte antigen (HLA)-matched or HLA-mismatched transplantation. Treatment intent was categorized as consolidation (13%), preemptive (61%), or salvage (27%) with 169 infusions administered as a single dose (29%) or according to adaptable dose-escalation regimens (71%). RESULTS: Acute graft-versus-host disease (GVHD) grades 1-2 and grade 3 occurred in 27% and 4% of cases, respectively; no extensive chronic GVHD or treatment-related mortality was observed. IL15-CIK-associated adverse events were predominantly mild. Disease clearance, assessed by the cumulative incidence of complete molecular remission, peaked at day 700, reaching 74% in the preemptive and 13% in the salvage setting. The five-year progression-free survival was 50% overall and highest (69%) in pediatric acute myeloid leukemia. The five-year overall survival (OS) was 71% in the consolidation, 61% in the preemptive, and 20% in the salvage setting. Multivariable analysis demonstrated significantly lower relapse rates with Campath compared with ATG, superior OS in myeloid malignancies, and reduced IL15-CIK efficacy in advanced disease. The median follow-up was 7.3 years. CONCLUSION: IL15-CIK monotherapy is feasible and safe and demonstrates promising relapse-preventive activity after hematopoietic stem-cell transplantation. Clinical outcomes are strongly influenced by disease burden at treatment initiation and previous serotherapy, supporting optimized patient selection and timing in future post-transplant immunotherapeutic strategies.

A phase 1/2 study of donor-derived anti-CD33 CAR T-cell therapy (VCAR33) for relapsed/refractory AML after allogeneic HCT

VCAR33, a donor-derived CD33-directed chimeric antigen receptor T-cell (CAR T) product, was developed to decrease relapse of high-risk acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) after allogeneic hematopoietic cell transplantation (alloHCT). We describe preclinical characterization of the VCAR33 construct, which was optimized for long-term antitumor surveillance based on killing and persistence assays. Prior to its use in post-alloHCT maintenance, we evaluated safety and efficacy of VCAR33 in a phase 1/2 clinical study for adults with relapsed or measurable residual disease (MRD)-positive CD33+ AML/MDS after alloHCT. Fifteen patients received VCAR33 across 2 arms stratified by disease burden: 7 patients in arm A (bone marrow blasts ≥5%) at dose level 1 (DL1; 1 × 106 CAR+ Ts per kg) and 8 patients in arm B (bone marrow blasts <5%) at DL1 (n = 5) and DL2 (3 × 106 CAR+ Ts per kg; n = 3). The study ended for nonsafety reasons before escalation to DL3 (1 × 107 CAR+ Ts per kg) and maximum tolerated dose was not determined. The most common treatment-related adverse event was cytokine release syndrome (93.3%; all <grade 3). Four patients (26.7%) experienced immune cell-associated neurotoxicity syndrome (1 ≥grade 3) and 1 patient (6.7%) had grade 3 acute graft-versus-host disease within 28 days of VCAR33 infusion. Fourteen patients (93.3%) had transient VCAR33 expansion. Overall response rate was 20%: 2 patients had complete remission with incomplete count recovery in arm A and 1 arm B patient achieved MRD clearance. This allogeneic CAR T product demonstrated acceptable safety and preliminary antileukemic activity. This trial was registered at www.clinicaltrials.gov as #NCT05984199.

Uncoupling toxicity from efficacy in donor selection for allogeneic hematopoietic cell transplantation: a retrospective cohort study using double machine learning

Haploidentical hematopoietic cell transplantation (HCT) offers potent graft-versus-tumor effects but is historically limited by higher non-relapse mortality (NRM) compared to matched unrelated (MUD) or related donors (MRD). To algorithmically decouple the competing risks of NRM and relapse, we analyzed 1,713 adult patients (MD Anderson discovery cohort) and 6,829 patients (registry replication cohorts) using a double machine-learning framework of Causal Survival Forests to estimate individualized treatment effects, while Random Survival Forests defined absolute prognostic risk. We found biological uncoupling of relapse and NRM: relapse was driven by disease biology, while NRM was governed by physiological reserve. Specifically, cardiovascular or cerebrovascular comorbidities acted as selective amplifiers of haploidentical toxicity-a "vascular penalty" that doubled mortality risk in the bootstrapped model (sub-distribution hazard ratio 2.09, 95% confidence interval 1.26-3.35). We developed a 3-factor nomogram (recipient age, vascular comorbidity, B-leader matching status) to identify an "Optimized Haploidentical" phenotype. Exploratory multivariable modeling suggested MUD consistently maximized predicted disease-free survival across all subgroups. Among haploidentical versus MRD comparisons, B-leader mismatch appeared to favor MRD across ages, while B-leader matched haploidentical donors in older patients (≥ 60 years) modeled near-equivalent DFS to MRD, representing a hypothesis-generating "zone of equivalence" requiring prospective validation.

Targeting Aurora kinase A to prevent GVHD and relapse after myeloablative allogeneic hematopoietic cell transplantation

The success of posttransplant cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis has driven efforts to optimize partner therapies that balance GVHD and relapse prevention. We report phase 1 dose-finding results of PTCy, sirolimus (SIR), and VIC-1911, a selective oral Aurora kinase A (AURKA) inhibitor, after myeloablative allogeneic hematopoietic cell transplantation (allo-HCT). Results from murine and in vitro studies informed the development of the novel drug combination. In the phase 1 trial, patients aged 18 to 60 years received myeloablative conditioning, followed by PTCy (50 mg/kg; days +3/+4), SIR (from day +5; target 8-12 ng/mL), and VIC-1911 (25, 50, or 75 mg twice daily; days +5 to +45). The primary end point was achieving <54% phosphorylated histone H3 serine 10 expression in CD4+ T cells by day +21. Preclinical models show that combining SIR with AURKA inhibition suppresses signaling downstream of CD28, enhancing GVHD prevention while leveraging the antileukemia activity of AURKA inhibition. In the phase 1 trial, the optimal VIC-1911 dose achieving target pathway inhibition without dose-limiting toxicities was 75 mg twice daily. Clinical outcomes included no grade 3 to 4 acute GVHD through day 180 (0%) and low rates of moderate/severe chronic GVHD (6%) and relapse (0%) through 1 year (5/16 received maintenance). The 1-year overall survival for this cohort was 94%. VIC-1911 at 75 mg twice daily, combined with PTCy and SIR, effectively suppressed AURKA activity, offering promising GVHD and relapse prevention with a favorable safety profile and promising early clinical outcomes. The trial was registered at www.clinicaltrials.gov as NCT05120570.

HCT Pre-App program: a telemedicine-based prehabilitation for allogeneic hematopoietic cell transplant candidates

Frailty has emerged as a key component of allo-HCT candidate assessment and is closely associated with transplant outcomes. Exercise-based prehabilitation may improve transplant candidacy, yet real-world implementation is limited. Our institution implemented a structured Frailty Program (FP) to assess frailty and introduce prehabilitation interventions. This study describes the program's evolution and evaluates the impact of prehabilitation. Between April 2021 and April 2025, 185 consecutive allo-HCT candidates were included in 3 sequential FP phases. In the first phase (No-Prehab, n = 76), patients underwent frailty assessment only. In the second phase (Pilot-Prehab, n = 59), patients received a home-based, nonsupervised prehabilitation program. In the third phase (Tele-Prehab, n = 50), patients participated in the HCT Pre-App Program, a structured digital telemedicine intervention supervised by rehabilitation physicians. Frailty was assessed at first consultation and HCT admission using the HCT Frailty Scale. Median prehabilitation duration was 6 weeks. Adherence was high across frailty groups (76%-88%), with no adverse events. Prehabilitation improved frailty status: fit patients increased from 22% to 42% in the Pilot-Prehab cohort (P = .009) and from 34% to 56% in the Tele-Prehab cohort (P = .001). Tele-Prehab independently increased the odds of being fit at admission (odds ratio [OR], 3.86; P = .001) and reduced frailty incidence (OR, 0.17; P = .031). One-year OS and NRM were comparable across cohorts (OS, 74.5%, 84.5%, and 78.1%; P = .367) with a trend toward lower NRM among prehabilitated patients (NRM, 14.6%, 5.1%, and 5.6%; P = .075). Frailty is dynamic in allo-HCT candidates, and results support how home-based digital prehabilitation improves fitness before transplantation.

Phase II Study of BCMA Chimeric Antigen Receptor T-Cell Therapy in Patients With Newly Diagnosed Multiple Myeloma Ineligible for or Not Proceeding to Autologous Stem-Cell Transplantation (CAREMM-001)

PURPOSE: Patients with newly diagnosed multiple myeloma (NDMM) who are ineligible for or not proceeding to autologous stem-cell transplantation (ASCT)-often because of age or frailty-have limited opportunities to receive multiple effective lines of therapy, underscoring the need for novel frontline strategies. METHODS: In this phase II, open-label, single-arm trial (ClinicalTrials.gov identifier: NCT05860036), patients received 3-4 cycles of protocol-allowed induction, followed by B-cell maturation antigen (BCMA) CAR-T infusion, and subsequent consolidation and lenalidomide maintenance. The primary end point was the rate of minimal residual disease (MRD) negativity (10-5) at Month three postinfusion. RESULTS: Between April 4, 2023, and December 26, 2024, 43 patients were screened, 40 were enrolled, and 36 received infusion (median age, 68 years [46-75]). In the infused cohort, the MRD negativity rate at Month three postinfusion was 100% (36 of 36; 95% CI, 90.3 to 100.0). With a median follow-up of 15.8 months postinfusion (range, 4.3-26.0), no MRD recurrence was observed. The complete response rate (CRR) increased from 33.3% (12 of 36; 95% CI, 18.6 to 51.0) preinfusion to 69.4% (25 of 36; 95% CI, 51.9 to 83.7) at Month 3% and 94.4% (34 of 36; 95% CI, 81.3 to 99.3) at last follow-up. The most common grade 3 to 4 adverse events were transient cytopenia, including lymphopenia (100%), neutropenia (88.9%), leukopenia (80.6%), thrombocytopenia (19.4%), and anemia (8.3%). Cytokine release syndrome occurred in 52.8% of patients (all grade 1 to 2), immune effector cell-associated neurotoxicity in 5.6% (all grade 1), and infections in 30.6% (grade ≥3 in 19.4%). No deaths or disease progressions occurred by cutoff. CONCLUSION: Frontline BCMA CAR-T therapy induces deep, rapid, and durable remissions with a manageable safety profile in the NDMM population ineligible for or not proceeding to ASCT. These findings support its investigation as a potentially practice-changing strategy for this population.

A phase 3 study of intensive chemotherapy with or without dasatinib in core-binding factor acute myeloid leukemia

Core-binding factor acute myeloid leukemia (CBF-AML) is associated with KIT mutations and deregulated expression of KIT. We report results from the randomized, open-label, phase 3 trial of intensive chemotherapy with or without the multikinase inhibitor dasatinib in adult patients with CBF-AML. Patients received "3+7" induction therapy, followed by 4 cycles of high-dose cytarabine; in the investigational arm, patients received dasatinib 100 mg daily on days 8 to 21 in induction, and on days 6 to 28 in consolidation cycles, followed by 12-month single-agent dasatinib 100 mg daily. Primary end point was event-free survival (EFS). Secondary end points included overall survival, relapse-free survival, and cumulative incidence of relapse. A total of 202 patients were randomly assigned to the standard arm (n = 102) and to the dasatinib arm (n = 100). Median age was 49 years (range, 18-77); 94 patients had t(8;21), 108 had inv(16)/t(16;16); and 58 (28.7%) patients had a KIT comutation. There was no statistically significant difference in EFS (hazard ratio, 0.92; 95% confidence interval, 0.63-1.33; P = .66) or secondary end points between treatment arms. There was also no significant difference in EFS in subgroup analyses according to age, CBF-AML type, and KIT mutation status. The incidence of serious adverse events was higher in the investigational arm (64%) than in the standard arm (36%). In patients with CBF-AML, the addition of dasatinib to intensive chemotherapy failed to improve survival outcomes. The addition of dasatinib was associated with an increase in toxicity. This trial was registered at www.ClinicalTrials.gov as NCT02013648.
