Summary
Goal: Our earlier research have indicated doubtlessly greater proliferative exercise of tumor cells in Chinese language sufferers with mantle-cell lymphoma (MCL) than these in Western. Given the success and tolerability of R-DA-EDOCH immunochemotherapy in treating aggressive B-cell lymphomas, we designed a potential, part 3 trial to discover the efficacy and security of alternating R-DA-EDOCH/R-DHAP induction remedy for younger sufferers with newly identified MCL. The first endpoint was the whole remission price (CRR) on the finish of induction (EOI).
Strategies: A complete of 55 sufferers had been enrolled. The CRR on the EOI was 89.1% [95% confidence interval (CI) 78%–96%], and the general response price was 98.1% (95% CI 90%–100%). Most sufferers with bone marrow involvement shortly attained minimal residual illness (MRD) damaging standing, with a 95.7% price on the EOI.
Outcomes: The three-year progression-free survival (PFS) and total survival charges had been 66.3% and 83.2%, respectively. No sufferers discontinued therapy due to hostile occasions. Univariate evaluation recognized pathologic morphology and TP53 mutations as danger components for PFS. Nevertheless, excessive tumor proliferative exercise and sure cytogenetic abnormalities confirmed no important hostile prognostic significance.
Conclusions: Intensive remedy based mostly on a excessive cytarabine dose and repeatedly administered EDOCH achieved a excessive MRD-negative price and gives an non-obligatory induction alternative for younger sufferers with MCL with high-risk components.

Introduction
Mantle-cell lymphoma (MCL) is a uncommon subtype of non-Hodgkin’s lymphoma, with a median total survival (OS) of solely 3–5 years within the period of chemotherapy1. MCL is clinically characterised by its heterogeneity. Over the previous 2 a long time, substantial advances have been made within the prognosis of sufferers with MCL, with the arrival of rituximab2–7. Presently, each the Nationwide Complete Most cancers Community (NCCN) and the European Society for Medical Oncology (ESMO) tips advocate for a number of immunotherapy regimens containing high-dose cytarabine (Ara-C) because the first-line therapy for transplantation-eligible sufferers with MCL. These remedies embrace mixtures similar to RCHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone)/R-DHAP (rituximab, dexamethasone, high-dose cytarabine, and cisplatin), R-maxi-CHOP/R-HD-Ara-C (rituximab plus high-dose cytarabine), BR (rituximab and bendamustine)/R-HD-Ara-C, R-Hyper CVAD (cyclophosphamide, vincristine, doxorubicin, and dexamethasone)/R-MA (high-dose methotrexate and cytarabine), and R-BAC (rituximab, bendamustine, and cytarabine)8,9. Amongst these remedies, the routine of RCHOP/R-DHAP adopted by autologous stem cell transplantation (ASCT) has steadily been utilized in medical research. In observations over as many as 15 years, half the handled sufferers remained alive, and 40% remained of their first remission after greater than a decade10. The not too long ago proposed BR/R-HD-Ara-C routine has additionally achieved excessive remission charges and favorable survival outcomes11. Though these regimens have considerably improved the prognosis of sufferers with MCL, the optimum routine stays elusive; no definitive remedy is near being obtainable, and relapses are inevitable. Furthermore, high-risk people, notably these with MIPI-c, TP53, MYC abnormalities, and aggressive histology, steadily have poor prognosis12.
With deepening understanding of the mechanism of MCL, researchers are more and more specializing in this area, and extra focused brokers have been utilized clinically, thus providing promise for enhancing MCL outcomes (Figure 1). Just lately, Bruton’s tyrosine kinase inhibitors (BTKi) have been trialed as first-line suggestions. Outcomes from the TRIANGLE routine trial have proven that incorporating BTKi into induction regimens enhances affected person outcomes, notably for high-risk sufferers13. Nevertheless, for younger sufferers who’re transplant candidates, the normal intensified therapy regimens already supply appreciable extension in disease-free survival. Integrating BTKi would possibly compromise affected person tolerance to rigorous immunotherapy regimens, amplify the chance of an infection or issues, and pose added monetary burden. Exactly figuring out the suitable populations for goal remedy is important, to make sure that sufferers unlikely to profit from solo immunochemotherapy obtain the very best tailor-made therapy, thus serving to sufferers obtain maximal survival advantages on the lowest price, and attaining customized therapy.
Key molecular mechanisms/rationales for focused brokers in mantle cell lymphoma (MCL). In MCL, sustained activation of the B-cell receptor complicated leads to mobile development and survival by a number of downstream signaling pathways. This determine reveals the principle signaling pathways and molecules concerned in B cell receptor activation, similar to Btk and NF-κB. Arrows level to downstream signaling molecules or their roles. White bins point out novel therapies that inhibit essential components of this signaling pathway.

Our revealed information have indicated that Chinese language sufferers with MCL are typically youthful with a better prevalence of TP53 deletion and MYC abnormalities than Western sufferers with MCL14. Given the efficacy and tolerability of the dose-enhanced immunochemotherapy R-DA-EDOCH routine (dose-adjusted routine, rituximab plus etoposide, dexamethasone, doxorubicin, cyclophosphamide, and vincristine) in sufferers with a number of high-risk aggressive B-cell lymphomas15 and the doubtless elevated tumor cell exercise in Chinese language sufferers, we designed alternating R-DA-EDOCH/R-DHAP induction remedy as an enhanced model of the RCHOP/R-DHAP routine for younger sufferers with newly identified MCL. We carried out a part III examine (NCT02858804) of this routine by utilizing the brand new induction process adopted by ASCT. On this context, we examined the routine’s efficacy and security.
Sufferers and strategies
Sufferers
The “EDOCH Alternating with DHAP for Newly Recognized Youthful MCL (BDH-MCL01)” medical trial was registered on July 17, 2016 (registration No. NCT02858804). Trial enrollment was accomplished in June 2020, with an estimated enrollment of 55 sufferers. Eligible sufferers 18–65 years of age who had a confirmed prognosis of MCL with translocation breakpoints at t (11;14) or cyclin D1 expression had been enrolled. The primary inclusion standards included Ann Arbor stage II–IV and Jap Cooperative Oncology Group performance-status rating (ECOG) ≤ 1. All particulars relating to the inclusion and exclusion standards are outlined within the Supplementary material.
Trial design and coverings
This open-label, nonrandomized trial was carried out in accordance with the Declaration of Helsinki. The trial protocol was accepted by the institutional ethics committees (IIT2021030-EC-1), and all concerned sufferers offered written knowledgeable consent.
Throughout induction, sufferers acquired alternating R-DA-EDOCH/R-DHAP for two cycles (4 programs in complete). Particular drug dosages and use are listed within the Supplementary material. Sufferers who achieved lower than partial remission (PR) stopped the trial, whereas the opposite sufferers continued with one other cycle of therapy. After the three cycles of inductive therapy, sufferers determined whether or not to proceed ASCT consolidation remedy or one other cycle of consolidation. R upkeep remedy (375 mg/m2, each 3 months for as many as 8 further doses) was really useful to all sufferers. Supportive care, together with the usage of polyethylene glycol recombinant human granulocyte stimulating issue and prophylactic anti-infective brokers, was offered on the discretion of the investigator. The medical trial course of is illustrated in Figure 2.

Endpoints and assessments
The first endpoint of this examine was the whole response price (CRR) on the finish of induction (EOI). Secondary endpoints included the target response price (ORR) on the EOI, progression-free survival (PFS), OS, and security and tolerability. Efficacy analysis was carried out in accordance with the Lugano 2014 standards with positron emission tomography-computed tomography (PET-CT) and/or computed tomography (CT) after each 2 programs of therapy. PFS was outlined because the time from the initiation of remedy to development, relapse, transformation, loss of life, or the final go to. OS was measured from the initiation of remedy to the date of loss of life for any motive or the final follow-up. Security and tolerability had been assessed all through the trial and as many as 90 days after the tip of therapy. Adversarial occasions (AEs) had been graded in accordance with the Widespread Terminology Standards for Adversarial Occasions, model 5.0.
Minimal residual illness (MRD) standing was the exploratory efficacy endpoint for this trial. We carried out MRD testing on the bone marrow (if concerned) at 3 time factors: after the 2nd and 4th programs of therapy, in addition to after the completion of induction remedy. MRD was assessed in bone marrow with eight-color multiparameter move cytometry, as beforehand described16. MRD negativity was outlined as a clonal malignant cell depend of −4 (0.01%).
Statistical evaluation
Sufferers had been repeatedly enrolled in accordance with the eligibility standards. We calculated the pattern measurement on the premise of the first endpoint, CRR. On the premise of the idea of a CRR of 75% on this trial and a CRR of 55% as historic reference values2, no less than 50 sufferers had been discovered to be required for the first evaluation. This pattern measurement was calculated in accordance with a take a look at energy (1-β) of 0.80, significance degree (α) of 0.05 (two-tailed take a look at), and dropout price as 0.10. A complete of 55 sufferers had been enrolled on this examine.
All efficacy endpoints had been analyzed within the intention-to-treat inhabitants (outlined as all sufferers who had undergone induction remedy), and security was assessed in all sufferers who acquired no less than one course of therapy.
Survival distributions had been estimated with the Kaplan-Meier methodology and in contrast with the two-sided log-rank take a look at. The hazard ratio and related two-sided 95% confidence interval (CI) had been calculated with a stratified Cox proportional-hazards mannequin. Comparisons of categorical variables amongst subgroups had been carried out with Fisher’s precise take a look at. For steady variables, Mann-Whitney U take a look at was used. P values ®) model 26.0 (IBM Corp., Armonk, NY, USA), STATA software program model 15.0 (Stata Corp., School Station, TX, USA), and R model 4.0.1.
Outcomes
Sufferers and therapy
We enrolled 55 sufferers with a median age of 53 years (vary: 37–65 years). The male to feminine ratio was 2.2:1, as detailed in Table 1. Fifty-three sufferers (94.6%) had advanced-stage illness (Ann Arbor stage Ⅲ–Ⅳ), and 38.2% sufferers exhibited B signs. A complete of 11.5% (6/52) of circumstances had been of blastocytic subtype and three.8% (2/52) of circumstances had been of pleomorphic subtype. Immunohistochemical research revealed a Ki-67 index ≥ 30% and p53 ≥ 50% in 43.6% (17/39) and 50.0% (18/36) of sufferers, respectively. TP53 mutation detection was obtainable in 42 sufferers, and the mutation frequency was 26.2% (11/42). Different molecular findings included MYC rearrangements/amplifications in 30.0%, 17p deletions in 18.9%, and 9p deletions in 34.1%. Notably, 16.7% of sufferers exhibited each TP53 mutations and 17p deletion, denoted TP53 double-allele abnormalities. Immunoglobulin heavy-chain variable area (IGHV) somatic hypermutation evaluation was carried out in 33 sufferers, 22 (66.7%) of whom had unmutated IGHV genes. Total, 61.8% of the sufferers had been recognized to have no less than one high-risk issue in accordance with danger stratification, pathological classification, and molecular genetic abnormalities (Table 1).
Baseline traits and danger stratification
All sufferers underwent no less than 2 cycles of alternating R-DA-EDOCH/R-DHAP immunochemotherapy, and efficiently accomplished an efficacy and security analysis (Figure 3). One affected person dropped out due to illness development throughout induction remedy. A complete of 28 sufferers underwent ASCT consolidation remedy, and 25 sufferers continued one other cycle of R-EDOCH/R-DHAP consolidation remedy as an alternative of ASCT. Amongst these not present process ASCT, 13 opted for R upkeep. Baseline traits and danger stratification of sufferers with/with out ASCT are listed in Table S1.

Excessive response price and deep remission
Among the many 55 response-evaluable sufferers, 98.1% achieved an ORR on the finish of alternating R-DA-EDOCH/R-DHAP inductive therapy (95% CI 90%–100%), and the CRR was 89.1% (95% CI 78%–96%). Calculations of CRR, ORR, and partial response charges had been carried out throughout numerous subgroups, similar to MIPI, MIPI-c, pathological traits, copy quantity variations, and essential tumor suppressor gene mutations. No important variations had been noticed in CRR and ORR amongst sufferers with numerous prognostic traits (Table 2). Sufferers with blastoid/pleomorphic MCL displayed a comparatively unfavorable therapy response, with CRR under 80% at EOI (Table 2).
EOI response charges amongst response-evaluable sufferers within the indicated subgroups
Of the 55 sufferers, 48 had bone marrow involvement at their preliminary prognosis. Of the 48 sufferers, 33 (68.8%) underwent bone marrow analysis after 2 therapy cycles. This quantity elevated to 45 of 48 (93.8%) after 4 therapy cycles, and additional elevated to 46 of 48 (95.8%) at EOI. A notable majority shortly reached MRD-negative standing. Particularly, the MRD-negativity charges had been 51.5% after 2 therapy cycles, 93.3% after 4 cycles, and 95.7% at EOI. Impressively, by the EOI, no detectable MRD was noticed amongst all sufferers attaining a whole response (CR, n = 49). Moreover, of the 5 sufferers with PR, MRD was undetectable within the bone marrow in 3 sufferers. An in depth breakdown of CR and MRD-negative charges at numerous levels is offered in Table S2.
Favorable tolerability
The alternating R-DA-EDOCH/R-DHAP routine was effectively tolerated, and no sufferers discontinued therapy due to insupportable treatment-related AEs. Hematologic AEs had been predominant, and 85.5% of sufferers skilled no less than one such occasion. Notably, 49.1% and 58.2% of the sufferers exhibited grade 3–4 leukopenia and neutropenia, respectively, whereas 14.5% skilled grade 3 neutropenic fever.
Relating to non-hematologic toxicity, we noticed no cases of grade 4 AEs. Essentially the most prevalent AEs had been grade 1–2 nausea/vomiting (25.4%), fatigue (17.9%), and peripheral neuritis (14.5%). Relating to an infection, 15 sufferers developed a pulmonary an infection, 7 sufferers had higher respiratory tract an infection, 4 sufferers had gingivitis, and a couple of sufferers skilled conjunctivitis and introduced with a grade 3 urinary tract an infection. Moreover, 2 sufferers (3.6%) encountered grade 2 arrhythmias throughout therapy. Different notable occasions included grade 2 thrombosis in 2 sufferers and grade 1 bleeding in 1 affected person. Detailed hematologic and non-hematologic AEs are listed in Table 3.
Hematologic and non-hematologic hostile occasions
Improved prognosis
Throughout a median follow-up of 48 months (vary: 6–112 months), the 3-year PFS and OS charges had been 66.3% and 83.2%, respectively (Figure 4). All through this era, 23 sufferers skilled illness development. Furthermore, 15 sufferers died: 2 due to treatment-related secondary leukemia (MCL nonetheless in CR), 1 due to cerebral infarction, 1 due to Pneumocystis carinii pneumonia throughout post-ASCT upkeep remedy, and the remaining 11 due to illness development.

Sequential ASCT consolidation and/or R upkeep barely elevated the CRR however considerably prolonged PFS (3-year PFS price: ASCT+R 83.6% vs. R 61.5% vs. with out ASCT/R 50.0%, P = 0.009, Figure 5). Nevertheless, the OS didn’t considerably differ throughout these teams. No important distinction in PFS and OS was noticed between sufferers with (n = 34) or with out (n = 9) excessive danger components (PFS P = 0.735, OS P = 0.612). Univariate evaluation revealed that blastoid/pleomorphic pathologic morphology (P = 0.003), TP53 mutation (P = 0.038), and TP53 double-allele occasions (P = 0.020) had been danger components for PFS underneath this therapeutic strategy (Figure 6). Apparently, components similar to excessive tumor proliferative exercise (e.g., Ki-67 ≥ 30% and MYC abnormalities) and sure damaging genetic abnormalities (e.g., deletions on chromosomes 17p and 9p) lacked statistically important hostile prognostic implications. To additional discover the consequences of therapy choices on the prognosis of high-risk sufferers, we carried out a subgroup evaluation of high-risk sufferers (with TP53 abnormalities or/and blastoid morphology). Excessive-risk sufferers who accomplished transplantation and upkeep remedy had higher prognosis than those that didn’t bear transplantation or upkeep remedy (Figure S1). Nevertheless, on this post-hoc evaluation, some subgroups had very small pattern sizes; due to this fact, statistical validity is missing, and additional analysis in bigger pattern sizes is critical.

Due to the excessive proportion of sufferers with bone marrow MRD negativity after intensive therapy, solely 2 sufferers had been bone marrow MRD-positive after induction remedy. This discovering would possibly clarify the absence of prognostic significance within the bone marrow MRD standing (P = 0.347).
Dialogue
MCL is a heterogeneous illness presenting various pathophysiological and genetic traits, medical signs, staging, and prognosis1. Numerous medical trials and real-world research have assessed the potential effectiveness of assorted therapy approaches2–4,17–24, but a standardized and healing resolution for MCL stays undefined. This potential medical trial underscores the efficacy and security of the first-line induction remedy of alternating R-DA-EDOCH/R-DHAP for younger sufferers with MCL. Impressively, most individuals attained CR [CRR 89% (95% CI 78%–96%)] and MRD-negative standing shortly, and confirmed notable tolerance. Apart from pathologic morphology and TP53 aberrance, excessive tumor proliferative exercise (similar to Ki-67 ≥ 30% and MYC abnormalities) and sure different genetic abnormalities confirmed no important hostile prognostic results. Furthermore, the sequential utility of ASCT consolidation and/or R upkeep (P = 0.019) considerably extended PFS in sufferers with MCL.
Within the period of immunochemotherapy, rituximab, high-dose cytarabine, and ASCT have emerged as the three cornerstones for therapy of younger sufferers with MCL. Prior analysis has indicated that roughly 55% of younger sufferers with MCL reached CR after finishing alternating R-CHOP/R-DHAP induction. Nevertheless, this price is arguably inadequate for a situation recognized for its excessive aggressiveness and unfavorable outcomes. Moreover, our earlier examine has indicated that Chinese language sufferers with MCL are youthful and have a better proportion of TP53 deletion and MYC abnormalities than western sufferers with MCL, each of that are unfavorable prognostic indicators, thereby suggesting doubtlessly enhanced tumor cell proliferation on this demographic14. Additional analyses of Alliance/GALGB 50303 medical trial information have indicated that R-DA-EPOCH improves PFS in intermediate-high-risk and high-risk sufferers with untreated diffuse giant B-cell lymphoma, with comparatively favorable tolerance15. Consequently, we hypothesized that alternating R-DA-EDOCH/R-DHAP wouldn’t be inferior to alternating R-CHOP/R-DHAP because the inductive remedy for eligible sufferers with MCL, and particular subgroups would profit from this routine. The CRR and the ORR on the EOI had been 89% (95% CI 78%–96%) and 98% (95% CI 90%–100%), respectively, surpassing these of different immunochemotherapeutic modalities similar to alternating R-CHOP/R-DHAP (55%) and R-hyper CVAD/R-MA (87%)2,4. The sufferers who accomplished the ASCT and R upkeep confirmed comparable survival in our examine, though the proportion of high-risk sufferers seemed to be better than these in earlier research10,25. Solely 51% sufferers underwent ASCT consolidation and/or R upkeep on this examine, partially due to COVID-19 disruptions lately. In alignment with findings from Le Gouill et al.6, the subgroup evaluation affirmed that ASCT consolidation and/or R upkeep did delay PFS in our examine. Nevertheless, no important OS benefit was noticed within the ASCT subgroup. The introduction of pioneering remedies after development, similar to BTKi and B-cell lymphoma-2 inhibitor (BCL2i), and/or participation in medical trials, have largely improved post-relapse survival amongst sufferers in whom immunochemotherapy has failed.
As anticipated, alternating R-DA-EDOCH/R-DHAP induction was usually well-tolerated, with manageable charges of hematologic and infectious AEs. Grade 3–4 leukopenia and neutropenia had been probably the most prevalent extreme AEs. Nonetheless, in contrast with earlier research, there have been restrict deadly infectious occasions underneath crucial help therapy, together with the utilization of granulocyte-stimulating issue and prophylactic anti-infective brokers. Crucially, this routine didn’t impair the profitable assortment of stem cells for ASCT and was appropriate for sufferers eligible for transplantation.
One urgent problem in modern lymphoma therapy is making certain an enduring response for many sufferers. MRD has emerged as a essential posttreatment end result predictor26. Amongst sufferers with MCL, substantial proof has highlighted that attaining deep remission, outlined as a CR paired with MRD negativity, correlates with prolonged survival11,27,28. Numerous strategies have been used for MRD monitoring within the context of MCL, however an ordinary detection methodology stays elusive. We used a prognostic analysis strategy by integrating radiologic imaging with eight-color multiparameter move cytometry of samples with bone marrow involvement. This strategy enabled complete analysis of each nodal/extranodal lesions and bone marrow involvement. The speed of CR with bone marrow MRD negativity on the EOI reached 88.7%, a price greater than these in prior research. In contrast with different research, this outcome indicated deeper remission and higher standing for the next remedy. Particularly, the longitudinal information additionally indicated fast remission in our cohort, thereby demonstrating the efficiency of the routine.
Given the restricted pattern measurement of our cohort, we didn’t carry out additional multivariate prognostic evaluation. In our univariate prognostic evaluation, traditionary danger components1,12 similar to MIPI, 17p deletion and 9p deletion didn’t considerably affect survival. Notably, danger components related to tumor proliferative exercise, similar to Ki-67 ≥ 30% and MYC abnormalities, exhibited no marked prognostic significance, as anticipated. The CRR and MRD-negative price had been comparatively excessive in these high-risk sufferers. These outcomes instructed that R-DA-EDOCH/R-DHAP remedy was an efficient induction routine in sufferers with excessive proliferative exercise. Nevertheless, this intensive therapy didn’t work effectively in sufferers with blastoid/pleomorphic pathologic morphology and sufferers with TP53 mutation and/or TP53 double-allele occasions. Along with outcomes from different research, our findings highlighted that immunochemotherapy alone may not absolutely overcome the hostile prognostic results of pathologic morphology and TP53 aberrance12,29. Over the previous decade, the therapeutic panorama for MCL has significantly advanced. Focused brokers, similar to immunomodulatory medicine (e.g., lenalidomide), BTKi, and BCL2i, have proven exceptional efficacy in sufferers with relapsed/refractory standing and are actually choices in first line remedy, notably for high-risk sufferers with MCL29. The important thing molecular mechanisms and rationale to be used of focused brokers in MCL are illustrated in Figure 1. Encouragingly, the subgroup evaluation of the ZUMA-2 medical trial indicated comparable ORRs for sufferers no matter blastoid morphology and TP53 mutation30. We eagerly anticipate additional research to supply deeper insights into high-risk MCL and to boost the survival prospects of those sufferers.
Conclusions
In abstract, alternating R-DA-EDOCH/R-DHAP inductive remedy confirmed spectacular efficacy and favorable tolerability in younger untreated sufferers with MCL on this potential examine. Beneath intensive remedy, sufferers confirmed a big enhance within the price of deep remission and MRD-negative standing. Intensive remedy based mostly on a excessive dose of cytarabine and repeatedly administered EDOCH might partially overcome the hostile prognostic results of high-risk components similar to excessive MIPI danger, excessive Ki-67, and MYC abnormalities. Nevertheless, this therapy can’t absolutely overcome the damaging results of blastoid pathological subtypes and TP53 mutations. Mixture remedy with focused medicine is critical to supply sufferers with further survival advantages. The alternating R-DA-EDOCH/R-DHAP routine presents a compelling induction alternative for younger sufferers with MCL, notably for these with excessive tumor proliferative exercise.
