Phase 1b dose-finding study of rituximab, lenalidomide, and ibrutinib (R2I) in patients with relapsed/refractory mantle cell lymphoma. Leuk Lymphoma 2023; 64:2225-2235. [PMID: 37740588 DOI: 10.1080/10428194.2023.2259528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 09/08/2023] [Indexed: 09/24/2023]
Abstract
Mantle cell lymphoma (MCL) is a rare non-Hodgkin lymphoma that frequently becomes chemoresistant over time. The distinct mechanisms of ibrutinib and lenalidomide provided a judicious rationale to explore the combination with anti-CD20 immunotherapy. In this phase 1b study (NCT02446236), patients (n = 25) with relapsed/refractory MCL received rituximab with escalating doses of lenalidomide (days 1-21) and ibrutinib 560 mg (days 1-28) of 28-day cycles. The MTD for lenalidomide was 20 mg; most common grade ≥3 adverse events were skin rashes (32%) and neutropenic fever (24%). The best ORR was 88%, CR rate was 83%, and median duration of response (DOR) was 36.92 months (95% CI 33.77, 51.37). Responses were seen even in refractory patients or with high-risk features (e.g. blastoid variant, TP53 mutation, Ki-67 > 30%). R2I was safe and tolerable in patients with R/R MCL.

Abstract
In this article, we will review current strategies for the front-line management of mantle cell lymphoma, an uncommon and biologically and clinically heterogeneous subtype of non-Hodgkin lymphoma that remains incurable with current therapies. Patients invariably relapse with time, and as a result, treatment strategies involve persistent therapy over the course of months to years, including induction, consolidation, and maintenance. Topics discussed include the historical development of various chemoimmunotherapy backbones with continued modifications to maintain and improve efficacy while limiting off-target, off-tumor effects. Chemotherapy-free induction regimens were developed initially for elderly or less fit patients though are now being utilized for younger, transplant-eligible patients due to deeper, more prolonged remission durations with fewer toxicities. The historic paradigm of recommending autologous hematopoietic cell transplant for fit patients in complete or partial remission is now being challenged based in part on ongoing clinical trials in which minimal residual disease directed approaches influence the consolidation strategy for any particular individual. The addition of novel agents, namely first and second generation Bruton tyrosine kinase inhibitors as well as immunomodulatory drugs, BH3 mimetics, and type II glycoengineered anti-CD20 monoclonal antibodies have been tested in various combinations with or without immunochemotherapy. We will attempt to help the reader by systematically explaining and simplifying the various approaches for treating this complicated group of disorders.

Treatment Outcomes and Survival Patterns of Asian Patients With Relapsed/Refractory Mantle Cell Lymphoma. J Hematol 2021; 10:187-195. [PMID: 34527115 PMCID: PMC8425802 DOI: 10.14740/jh890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 08/10/2021] [Indexed: 11/11/2022] Open
Abstract
Background Mantle cell lymphoma (MCL) is widely considered an incurable malignancy even with current therapies and relapsed/refractory (R/R) disease to primary treatment remains common. With improved treatment guidelines and the advent of novel agents, patients are increasingly being treated with more lines of regimens. However, outcomes after each line of treatment remain poorly characterized, especially in the Asian population. In this paper, we described the survival outcomes in a group of R/R MCL patients. Methods We retrospectively studied 35 patients with R/R MCL between 1998 and 2020 at the National Cancer Centre Singapore. Patients were followed longitudinally throughout their disease course. Overall survival (OS) and progression-free survival (PFS) were determined by the Kaplan-Meier method. Results The median OS and PFS from diagnosis were 105 and 40 months, respectively. After first relapse, the median OS and PFS were 52 and 19 months, post-second relapse 32 and 8 months, and post-third relapse 12 and 6 months, respectively. Patients older than 65 years at first relapse had shorter survival (median OS: 22 vs. 55 months, P = 0.0417; median PFS: 9 vs. 29 months, P = 0.001). Early treatment failure after first line therapy was also associated with worse survival outcomes (median OS: 13 vs. 55 months, P < 0.001; median PFS: 9 vs. 26 months, P < 0.001). Conclusion With each relapse, survival outcomes for patients with MCL are worse. Novel treatment and contemporary outcomes of R/R MCL are encouraging and support the need for continued research in this area.

Abstract
The systematic application of next-generation sequencing to large cohorts of oncologic samples has opened a Pandora's box full of known and novel genetic lesions implicated in different steps of cancer development and progression. Narrowing down to B cell malignancies, many previously unrecognized genes emerged as recurrently mutated. The challenge now is to determine how the mutation in a given gene affects the biology of the disease, paving the way to functional genomics studies. Mutations in NOTCH family members are shared by several disorders of the B series, even if with variable frequencies and mutational patterns. In silico predictions, revealed that mutations occurring in NOTCH receptors, despite being qualitatively different, may have similar effects on protein processing, ultimately leading to enhanced pathway activation. The discovery of mutations occurring also in downstream players, either potentiating positive signals or compromising negative regulators, indicates that multiple mechanisms in neoplastic B cells concur to activate NOTCH pathway. These findings are supported by results obtained in chronic lymphocytic leukemia and splenic marginal zone B cell lymphoma where deregulation of NOTCH signaling has been functionally characterized. The emerging picture confirms that NOTCH signaling is finely tuned in cell- and microenvironment-dependent ways. In B cell malignancies, it contributes to the regulation of proliferation, survival and migration. However, deeper biological studies are needed to pinpoint the contribution of NOTCH in the hierarchy of events driving B cells transformation, keeping in mind its role in normal B cells development. Because of its relevance in leukemia and lymphoma biology, the NOTCH pathway might represent an appealing therapeutic target: the next few years will tell whether this potential will be fulfilled.

Abstract
This study intended to present a practicable prognostic nomogram for patients with mantle cell lymphoma (MCL). The clinical data of 281 patients were reviewed. A nomogram that could predict overall survival (OS) was constructed based on the Cox proportional hazard model. To compare the capacity of the nomogram with the International Prognostic Index (IPI) and MCL International Prognostic Index (MIPI) scoring systems, we used the concordance index (C-index) to validate the veracity and the calibration curve. Age, Eastern Cooperation Oncology Group, lactate dehydrogenase, white cell count and Ki-67 were independent prognostic factors in the multivariate analysis and were subsequently included in the nomogram construction. The C-index was 0.81 and 0.79 in the primary and validation cohorts, respectively, which were superior to the predictive capacity of the IPI and MIPI systems in both cohorts. The nomogram makes it possible for physicians to predict patient OS individually and correctly, but certain limitations are noted.

Abstract
Mutations and epigenetic alterations are key events in transforming normal cells to cancer cells. Mantle cell lymphoma (MCL), a non-Hodgkin's lymphoma of the B-cell, is an aggressive malignancy with poor prognosis especially for those patients who are resistant to the frontline drugs. There is a great need to describe the molecular basis and mechanism of drug resistance in MCL to develop new strategies for treatment. We reviewed frequent somatic mutations and mutations involving the B-cell pathways in MCL and discussed clinical trials that attempted to disrupt these gene pathways and/or epigenetic events. Recurrent gene mutations were discussed in the light of prognostic and therapeutic opportunity and also the challenges of targeting these lesions. Mutations in the ATM, CCND1, TP53, MLL2, TRAF2 and NOTCH1 were most frequently encountered in mantle cell lymphoma. Translational models should be built that would assess mutations longitudinally to identify important compensatory, pro-survival and anti-apoptic pathways and actionable genetic targets.

Abstract
RATIONALE Although still relatively rare, multiple primary malignant neoplasms (MPMNs) have been increasingly reported in recent years. PATIENT CONCERNS AND DIAGNOSES A 65-year-old man was referred to our hospital for a painless, incidental left axillary lump. Ultrasound showed enlarged left axillary lymph nodes. An excisional biopsy was conducted on 3 lymph nodes. The pathological diagnosis was determined to be metastatic adenocarcinoma and mantle cell lymphoma (MCL) in the lymph nodes. Further physical examination of the patient yielded a 1.5-cm hard, left subareolar mass. INTERVENTIONS AND OUTCOMES The patient underwent modified radical mastectomy. The diagnosis was grade II invasive ductal carcinoma (stage IIA). The axillary lymph node showed MCL (stage I, group A), but not metastatic ductal carcinoma. The patient received chemotherapy, including 6 courses of CHOP (A chemotherapy protocol consists of cyclophosphamide 1.2 g day 1, doxorubicin 80 mg day 1, vindesine 4 mg day1, and prednisone 90 mg from day 1 to 5) for lymphoma and breast cancer. The patient was also administered endocrine therapy. After a 54-month follow-up, the patient was well with no evidence of disease. LESSONS MPMNs are easily misdiagnosed as a primary and metastatic tumor, leading to delayed or erroneous treatment. Male breast cancer in a patient with MCL is rare. Early diagnosis and proper therapy are necessary for an optimal prognosis. Further studies are required to define the mechanisms and risk factors of MPMNs.

Clinical utility of recently identified diagnostic, prognostic, and predictive molecular biomarkers in mature B-cell neoplasms. Mod Pathol 2017; 30:1338-1366.

Abstract
Genomic profiling studies have provided new insights into the pathogenesis of mature B-cell neoplasms and have identified markers with prognostic impact. Recurrent mutations in tumor-suppressor genes (TP53, BIRC3, ATM), and common signaling pathways, such as the B-cell receptor (CD79A, CD79B, CARD11, TCF3, ID3), Toll-like receptor (MYD88), NOTCH (NOTCH1/2), nuclear factor-κB, and mitogen activated kinase signaling, have been identified in B-cell neoplasms. Chronic lymphocytic leukemia/small lymphocytic lymphoma, diffuse large B-cell lymphoma, follicular lymphoma, mantle cell lymphoma, Burkitt lymphoma, Waldenström macroglobulinemia, hairy cell leukemia, and marginal zone lymphomas of splenic, nodal, and extranodal types represent examples of B-cell neoplasms in which novel molecular biomarkers have been discovered in recent years. In addition, ongoing retrospective correlative and prospective outcome studies have resulted in an enhanced understanding of the clinical utility of novel biomarkers. This progress is reflected in the 2016 update of the World Health Organization classification of lymphoid neoplasms, which lists as many as 41 mature B-cell neoplasms (including provisional categories). Consequently, molecular genetic studies are increasingly being applied for the clinical workup of many of these neoplasms. In this review, we focus on the diagnostic, prognostic, and/or therapeutic utility of molecular biomarkers in mature B-cell neoplasms.

Abstract
Mantle cell lymphoma (MCL) is a type of non-Hodgkin lymphoma (NHL) with aggressive disease characteristics resulting in multiple relapses after initial treatment. Lenalidomide is an immunomodulatory agent approved in the US for patients with relapsed/refractory MCL following bortezomib based on results from 3 multicenter phase II studies (2 including relapsed/refractory aggressive NHL and 1 focusing on MCL post-bortezomib). The purpose of this report is to provide longer follow-up on the MCL-001 study (follow-ups were 6.8 [NHL-002], 7.6 [NHL-003], and 52.2 [MCL-001] months). The 206 relapsed MCL patients treated with single-agent lenalidomide (25 mg/day PO, days 1 to 21 every 28-days) had a median age of 67 years (63% ≥65 years), 91% with stage III/IV disease, and 50% with ≥4 previous treatment regimens. With a median follow-up of X, the combined best overall response rate (ORR) was 33% (including 11% with complete remission [CR]/CR unconfirmed CRu). Lenalidomide produced rapid and durable responses with a median time to response of 2.2 months and median duration of response (DOR) of 16.6 months (95% CI: 11.1%-29.8%). The safety profile was consistent and manageable; myelosuppression was the most common adverse event (AE). Overall, single-agent lenalidomide showed consistent efficacy and safety in multiple phase II studies of heavily pretreated patients with relapsed/refractory MCL, including those previously treated with bortezomib.

Abstract
At our center, relapsed mantle cell lymphoma (MCL) can be treated with maintenance therapy composed of consecutive low-dose lenalidomide and short-term, high-dose dexamethasone (LD regimen), which achieves good responses (longer overall survival and progression-free survival) and low toxicity. Cereblon is probably targeted by both lenalidomide and dexamethasone, which leads to synergistic cytotoxicity in MCL by inhibiting the interleukin-6/signal transducer and activator of transcription 3 (IL-6/STAT3), phosphatidylinositol 3-kinase (PI3K)/AKT and AKT2/Forkhead box O3 (FOXO3A)/BCL2-like 11 (BIM) pathways. The two drugs synergistically inhibit the same pathways, but through different sites. Cereblon was found expressed in most of the MCL tissues (91.3% positivity). Moreover, cereblon expression is positively correlated with LD regimen sensitivity: long-term lenalidomide exposure downregulates cereblon and induces multi-drug resistance against lenalidomide, dexamethasone, cytarabine, cisplatin, and methotrexate in vitro. Removal of lenalidomide resensitizes lenalidomide-resistant MCL cells to lenalidomide and dexamethasone. Our work suggests that rotating the LD regimen with other regimens would improve MCL maintenance therapy.

Abstract
Mantle cell lymphoma is a clinically heterogeneous disease occurring within a heterogeneous patient population, highlighting a need for personalized therapy to ensure optimal outcomes. It is therefore critical to understand the benefits and risks associated with both intensive and deintensified approaches. In the following review we provide a therapeutic roadmap to strategically guide treatment for newly diagnosed and relapsed/refractory patients highlighting pivotal and recently published results involving known and novel therapies.

Abstract
The resistance of apoptosis in cancer cells is pivotal for their survival and is typically ruled by mutations or dysregulation of core apoptotic cascade. Mantle cell lymphoma (MCL) is a non-Hodgkin's B-cell malignancy expressing higher anti-apoptotic proteins providing survival advantage. B-PAC-1, a procaspase activating compound, induces apoptosis by sequestering Zn bound to procaspase-3, but the amino acids holding Zn in Caspase-3 is not known. Here we show that reintroduction of WT caspase-3 or 7 in Caspase3-7 double knock-out (DKO) mouse embryonic fibroblasts (MEF) promoted B-PAC-1 to induce apoptosis (27-43%), but not in DKO MEFs or MEFs expressing respective Casp3-7 catalytic mutants (12-13%). Using caspase-6 and -9 exosite analysis, we identified and mutated predicted Zn-ligands in caspase-3 (H108A, C148S and E272A) and overexpressed into DKO MEFs. Mutants carrying E272A abrogated Zn-reversal of apoptosis induced by B-PAC-1 via higher XIAP and smac expressions but not in H108A or C148S mutants. Co-immunoprecipitation analysis revealed stronger XIAP-caspase-3 interaction suggesting a novel mechanism of impulsive apoptosis resistance by disrupting predicted Zn-ligands in caspase-3. B-PAC-1 sponsored apoptosis in MCL cell lines (30-73%) via caspase-3 and PARP cleavages accompanied by loss of Mcl-1 and IAPs including XIAP while Zn substantially abrogated B-PAC-1-driven apoptosis (18-36%). In contrary, Zn is dispensable to inhibit staurosporin, bendamustine, ABT199 or MK206-induced apoptosis. Consistent to cell lines, B-PAC-1 stimulated cell death in primary B-lymphoma cells via caspase-3 cleavage with decline in both Mcl-1 and XIAP. This study underscores the first genetic evidence that B-PAC-1 driven apoptosis is mediated via Zn chelation.

Abstract
BACKGROUND Lenalidomide, an immunomodulatory drug with antineoplastic and antiproliferative effects, showed activity in many single-group studies in relapsed or refractory mantle cell lymphoma. The aim of this randomised study was to examine the efficacy and safety of lenalidomide versus best investigator's choice of single-agent therapy in relapsed or refractory mantle cell lymphoma. METHODS The MCL-002 (SPRINT) study was a randomised, phase 2 study of patients with mantle cell lymphoma aged 18 years or older at 67 clinics and academic centres in 12 countries who relapsed one to three times, had Eastern Cooperative Oncology Group performance status of 0-2, at least one measurable lesion to be eligible, and who were ineligible for intensive chemotherpy or stem-cell transplantation. Using a centralised interactive voice response system, we randomly assigned (2:1) patients in a permuted block size of six to receive lenalidomide (25 mg orally on days 1-21 every 28 days) until progressive disease or intolerability, or single-agent investigator's choice of either rituximab, gemcitabine, fludarabine, chlorambucil, or cytarabine. Randomisation was stratified by time from diagnosis, time from last anti-lymphoma therapy, and previous stem-cell transplantation. Individual treatment assignment between lenalidomide and investigator's choice was open label, but investigators had to register their choice of comparator drug before randomly assigning a patient. Patients who progressed on investigator's choice could cross over to lenalidomide treatment. We present the prespecified primary analysis results in the intention-to-treat population for the primary endpoint of progression-free survival, defined as the time from randomisation to progressive disease or death, whichever occurred first. Patient enrolment is complete, although treatment and collection of additional time-to-event data are ongoing. This study is registered with ClinicalTrials.gov, number NCT00875667. FINDINGS Between April 30, 2009, and March 7, 2013, we enrolled 254 patients in the intention-to-treat population (170 [67%] were randomly assigned to receive lenalidomide, 84 [33%] to receive investigator's choice monotherapy). Patients had a median age of 68·5 years and received a median of two previous regimens. With a median follow-up of 15·9 months (IQR 7·6-31·7), lenalidomide significantly improved progression-free survival compared with investigator's choice (median 8·7 months [95% CI 5·5-12·1] vs 5·2 months [95% CI 3·7-6·9]) with a hazard ratio of 0·61 (95% CI 0·44-0·84; p=0·004). In the 167 patients in the lenalidomide group and 83 patients in the investigator's choice group who received at least one dose of treatment the most common grade 3-4 adverse events included neutropenia (73 [44%] of 167 vs 28 [34%] of 83) without increased risk of infection, thrombocytopenia (30 [18%] vs 23 [28%]), leucopenia (13 [8%] vs nine [11%]), and anaemia (14 [8%] vs six [7%]). INTERPRETATION Patients with relapsed or refractory mantle cell lymphoma ineligible for intensive chemotherapy or stem-cell transplantation have longer progression-free survival, with a manageable safety profile when treated with lenalidomide compared with monotherapy investigator's choice options.

Abstract
Mantle cell lymphoma (MCL) is an aggressive B cell lymphoma with a poor prognosis. It is characterized by the t(11;14)(q13;q32) translocation, resulting in overexpression of CCND1. Morphologically, MCL is categorised into two types: classical MCL (cMCL) and aggressive MCL (aMCL), with a proportion of cMCL progressing to develop into aMCL. miRNAs are currently considered to be important regulators for cell behavior and are deregulated in many malignancies. Although several genetic alterations have been implicated in the transformation of cMCL to aMCL, the involvement of miRNAs in transformation is not known. In an effort to identify the miRNAs related to the transformation of MCL, miRNA microarray analyses were used for cMCL and aMCL cases. These analyses demonstrated significant differences in the expression of seven microRNAs based on a t-test (p-value <0.05); miR-15b was greatly upregulated in aMCL. Locked nucleic acid in situ hybridization showed increased staining of miR-15b in formalin-fixed paraffin-embedded sections of aMCL. These results correlated well with the microRNA microarray analysis. Although the molecular functions of miR-15b are largely unknown, it has been found to be associated with the cell cycle and apoptosis. However, the physiological significance of increased miR-15b in MCL is still unknown. Our present findings suggest that the upregulated expression of miR-15b is likely to play an important role in the transformation of cMCL to aMCL.

Abstract
In most cases of relapsed/refractory mantle cell lymphoma (MCL), patients respond to salvage therapy, though typically responses are partial and/or transient followed by disease progression, even with newer agents (e.g., ibrutinib). In this multicenter, open-label, single-arm, phase II study, patients with relapsed/refractory non-blastoid MCL received bendamustine 90 mg/m(2) (days 1 and 2) and rituximab 375 mg/m(2) (day 1) for 6 planned 28-day cycles. Functional imaging with 18-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) was conducted at baseline and after cycle 6. Forty-five patients were enrolled (median age, 70 years; 82 % stage IV disease; median number of prior chemotherapies, 2 [range, 1-4]), showing an overall response rate (ORR; primary efficacy measure) of 82 % (complete response [CR], 40 %; partial response, 42 %). In the 32 patients with complete 18F-FDG PET/CT data, 75 % achieved a complete metabolic response. Median duration of response was 1.6 years, 1-year progression-free survival was 67 %, and 3-year overall survival was 55 %. Main non-hematologic adverse events were nausea (69 %), fatigue (56 %), decreased appetite (42 %), constipation (38 %), diarrhea (36 %), vomiting (36 %), and decreased weight (31 %). Grade 3/4 neutropenia and lymphopenia occurred in 44 and 89 % of patients, respectively. ORR and CR rate compared favorably with single-agent ibrutinib (ORR, 67 %; CR, 23 %); bendamustine-rituximab is an effective therapy with manageable toxicity in relapsed/refractory MCL.

Abstract
The recent World Health Organization (WHO) classification defines mantle cell lymphoma (MCL) as a distinct entity characterized by a unique immunophenotype and a molecular hallmark of chromosomal translocation t(11;14)(q13;q32). We report an unusual case of an advanced stage of CD5 negative MCL with a blastoid variant with a massive bone marrow (BM) necrosis as an initial presenting feature, with no adenopathy or hepatosplenomegaly. The pathologic features showed blastoid variant of MCL and flow cytometry showed that the tumor cells were CD5−, CD19+, CD20+, FMC-7+, CD23−, and lambda light chain restricted. Chromosomal analysis, using karyotype and fluorescent in situ hybridization (FISH), demonstrated karyotypic abnormalities in addition to the t(11;14). Our case study may be reported as a unique case of CD5− blastic MCL with unusual presentation and findings which made the diagnosis of MCL difficult.

Abstract
Patients with mantle cell lymphoma (MCL) generally respond to first‐line immunochemotherapy, but often show chemoresistance upon subsequent relapses, with poor outcome. Several studies of the immunomodulator, lenalidomide, have demonstrated its activity in MCL including the MCL‐001 study in relapsed/refractory patients who had failed defined prior therapies of anthracyclines or mitoxantrone, cyclophosphamide, rituximab and also bortezomib. We present here the long‐term efficacy follow‐up of the prospective phase II MCL‐001 study (N = 134), including new exploratory analyses with baseline Ki‐67 (MIB1), a biological marker of tumour proliferation. With longer follow‐up, lenalidomide showed a 28% overall response rate [ORR; 8% complete response (CR)/CR unconfirmed (CRu)]. Median duration of response (DOR), progression‐free survival and overall survival were 16·6, 4·0 and 20·9 months, respectively. Myelosuppression continued to be the most common grade 3/4 toxicity. Several studies of MCL patients treated with chemotherapy, rituximab and bortezomib have shown an inverse association between survival and Ki‐67. Ki‐67 data in 81/134 MCL‐001 patients showed similar ORRs in both low (<30% or <50%) versus high (≥30% or ≥50%) Ki‐67–expressing groups, yet lower Ki‐67 levels demonstrated superior CR/CRu, DOR and survival outcomes. Overall, lenalidomide showed durable efficacy with a consistent safety profile in heavily pretreated, relapsed/refractory MCL post‐bortezomib.

Abstract
The diagnosis of B-cell non-Hodgkin lymphomas has changed significantly over the past few decades as new immunophenotypic markers, molecular subtype classification schemes, and novel biomarkers have emerged. Meanwhile, there has been an increasing emphasis on individualizing treatment approaches in accordance with a biologic heterogeneity that has been uncovered within many of the individual B-cell lymphoma entities. The application of high-throughput genomic sequencing to B-cell lymphomas has yielded large amounts of valuable information. The data encompass discoveries essential to an understanding of pathogenesis, clonal or tumoral evolution, and identification of biomarkers that may be useful for prognostic or therapeutic considerations. The following review discusses several of the more common, primarily tissuebased B-cell lymphomas, with a focus on pathologic classification and certain phenotypic characteristics or genetic lesions that apply to refinement of diagnosis and therapy.

Abstract
BACKGROUND We previously developed an antibody-avidin fusion protein (ch128.1Av) specific for the human transferrin receptor 1 (TfR1; CD71) to be used as a delivery vector for cancer therapy and showed that ch128.1Av delivers the biotinylated plant toxin saporin-6 into malignant B cells. However, as a result of widespread expression of TfR1, delivery of the toxin to normal cells is a concern. Therefore, we explored the potential of a dual targeted lentiviral-mediated gene therapy strategy to restrict gene expression to malignant B cells. Targeting occurs through the use of ch128.1Av or its parental antibody without avidin (ch128.1) and through transcriptional regulation using an immunoglobulin promoter. METHODS Flow cytometry was used to detect the expression of enhanced green fluorescent protein (EGFP) in a panel of cell lines. Cell viability after specific delivery of the therapeutic gene FCU1, a chimeric enzyme consisting of cytosine deaminase genetically fused to uracil phosphoribosyltransferse that converts the 5-fluorocytosine (5-FC) prodrug into toxic metabolites, was monitored using the MTS or WST-1 viability assay. RESULTS We found that EGFP was specifically expressed in a panel of human malignant B-cell lines, but not in human malignant T-cell lines. EGFP expression was observed in all cell lines when a ubiquitous promoter was used. Furthermore, we show the decrease of cell viability in malignant plasma cells in the presence of 5-FC and the FCU1 gene. CONCLUSIONS The present study demonstrates that gene expression can be restricted to malignant B cells and suggests that this dual targeted gene therapy strategy may help to circumvent the potential side effects of certain TfR1-targeted protein delivery approaches.

Abstract
Obatoclax, a BH3 mimetic inhibitor of anti-apoptotic Bcl-2 proteins, demonstrates synergy with bortezomib in preclinical models of mantle cell lymphoma (MCL). This phase I/II study assessed obatoclax plus bortezomib in patients with relapsed/refractory MCL. Twenty-three patients received obatoclax 30 or 45 mg plus bortezomib 1.0 or 1.3 mg/m(2), administered intravenously on days 1, 4, 8 and 11 of a 21-day cycle. In phase I, the combination was feasible at all doses. Obatoclax 45 mg plus bortezomib 1.3 mg/m(2) was selected for phase II study. Common adverse events were somnolence (87%), fatigue (61%) and euphoric mood (57%), all primarily grade 1/2. Grade 3/4 events included thrombocytopenia (21%), anemia (13%) and fatigue (13%). Objective responses occurred in 4/13 (31%) evaluable patients (three complete and one partial response). Six patients (46%) had stable disease lasting ≥ 8 weeks. Obatoclax plus bortezomib was feasible, but the synergy demonstrated in preclinical models was not confirmed.

Clinical features and treatment outcomes in patients with mantle cell lymphoma in Korea: Study by the Consortium for Improving Survival of Lymphoma. Blood Res 2014; 49:15-21. [PMID: 24724062 PMCID: PMC3974951 DOI: 10.5045/br.2014.49.1.15] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2013] [Revised: 12/05/2013] [Accepted: 02/19/2014] [Indexed: 12/11/2022] Open
Abstract
Background We investigated the clinical features and treatment outcomes of patients with mantle cell lymphoma (MCL) in Korea. Methods We retrospectively analyzed the clinical characteristics and prognosis of 131 patients diagnosed with MCL between January 2004 and December 2009 at 15 medical centers in Korea; all patients received at least 1 chemotherapeutic regimen for MCL. Results The median age for the patients was 63 years (range, 26-78 years), and 77.9% were men. A total of 105 patients (80.1%) had stage III or IV MCL at diagnosis. Fifty-two patients (39.7%) were categorized with high- or high-intermediate risk MCL according to the International Prognostic Index (IPI). Eighteen patients (13.7%) were in the high-risk group according to the simplified MCL-IPI (MIPI). The overall incidence of extranodal involvement was 69.5%. The overall incidence of bone marrow and gastrointestinal involvements at diagnosis was 41.2% and 35.1%, respectively. Cyclophosphamide, doxorubicin, vincristine, prednisolone, and rituximab were used frequently as the first-line treatment (41.2%). With a median follow-up duration of 20.0 months (range, 0.2-77.0 months), the overall survival (OS) at 2 years was 64.7%, while the event-free survival (EFS) was 39.7%. Multivariate analysis showed that the simplified MIPI was significantly associated with OS. However, the use of a rituximab-containing regimen was not associated with OS and EFS. Conclusion Similar to results from Western countries, the current study found that simplified MIPI was an important prognostic factor in Korean patients with MCL.

Abstract
Purpose We designed a gene profiling experiment to identify genes involved in secondary drug resistance in mantle cell lymphomas (MCL). Experimental Design We obtained paired tissue samples collected from the same patients before treatment and after relapse or progression. Variations in gene expression between the 2 samples were estimated for 5 patients. For each gene, the mean variation was estimated for patients with a refractory primary tumor and for responders who developed secondary drug resistance. Nine genes of interest were selected on the basis of the magnitude and statistical significance of the variation of expression in responders and non-responders. Results BMP7 was the only one with significantly increased expression at relapse in patients who developed secondary resistance. Validation of BMP7 as a key gene involved in secondary resistance was performed using cultures of cell line. Incubation of BMP7 with MCL cell lines increased their resistance to bortezomib and cytarabine, while inhibition of BMP7 expression by siRNA correlated with increased cell death linked to drug application. Conclusion Variations in gene expression after treatment point out BMP7 as a key gene involved in secondary resistance in mantle cell lymphoma.

Abstract
PURPOSE Although dose-intensive strategies or high-dose therapy induction followed by autologous stem-cell transplantation have improved the outcome for patients with mantle-cell lymphoma (MCL), most eventually relapse and subsequently respond poorly to additional therapy. Bortezomib (in the United States) and temsirolimus (in Europe) are currently the only two treatments approved for relapsed disease. Lenalidomide is an immunomodulatory agent with proven tumoricidal and antiproliferative activity in MCL. The MCL-001 (EMERGE) trial is a global, multicenter phase II study examining the safety and efficacy of lenalidomide in patients who had relapsed or were refractory to bortezomib. PATIENTS AND METHODS Lenalidomide 25 mg orally was administered on days 1 through 21 every 28 days until disease progression or intolerance. Primary end points were overall response rate (ORR) and duration of response (DOR); secondary end points included complete response (CR) rate, progression-free survival (PFS), overall survival (OS), and safety. RESULTS In all, 134 patients were enrolled with a median age of 67 years and a median of four prior therapies (range, two to 10 prior therapies). The ORR was 28% (7.5% CR/CR unconfirmed) with rapid time to response (median, 2.2 months) and a median DOR of 16.6 months (95% CI, 7.7 to 26.7 months). Median PFS was 4.0 months (95% CI, 3.6 to 5.6 months), and median OS was 19.0 months (95% CI, 12.5 to 23.9 months). The most common grade 3 to 4 adverse events were neutropenia (43%), thrombocytopenia (28%), anemia (11%), pneumonia (8%), and fatigue (7%). CONCLUSION The MCL-001 study demonstrated durable efficacy of lenalidomide with a predictable safety profile in heavily pretreated patients with MCL who had all relapsed or progressed after or were refractory to bortezomib.

Abstract
BACKGROUND SGI-1776 is a small-molecule Pim kinase inhibitor that primarily targets c-MYC-driven transcription and cap-dependent translation in mantle cell lymphoma (MCL) cells. Bendamustine is an alkylating chemotherapeutic agent approved for use in B-cell lymphoma that is known to induce DNA damage and initiate response to repair. MATERIALS AND METHODS Our studies were conducted in MCL cell lines JeKo-1 and Mino, as well as primary B-cell lymphoma samples of MCL and splenic marginal zone lymphoma (SMZL), where we treated cells with SGI-1776 and bendamustine. We measured levels of cellular apoptosis, macromolecule synthesis inhibition, and DNA damage induced by drug treatments. RESULTS Both SGI-1776 and bendamustine effectively induced apoptosis as single agents, and when used in combination, an additive effect in cell killing was observed in MCL cell lines JeKo-1 and Mino, as well as in MCL and SMZL primary cells. As expected, SGI-1776 was effective in inducing a decrease of global RNA and protein synthesis, and bendamustine significantly inhibited DNA synthesis and generated a DNA damage response. When used in combination, the effects were intensified in DNA, RNA, and protein synthesis inhibition compared with single-agent treatments. CONCLUSION These data provide a foundation and suggest the feasibility of using Pim kinase inhibitors in combination with chemotherapeutic agents such as bendamustine in B-cell lymphoma.

Abstract
We developed here a vaccine-identical measles virus (MV) as an oncolytic agent against mantle cell lymphoma (MCL), an aggressive B-cell non-Hodgkin's lymphoma that is difficult to cure but radiosensitive. We armed the virus with the sodium-iodide symporter, which concentrates iodide within infected cells enabling noninvasive imaging and combination radiovirotherapy. Through high-resolution in vivo and ex vivo imaging, we visualized the spread of infections in primary and metastatic tumors for over 2 weeks after therapy, documenting homogeneous virus seeding and spread restricted to perfused tissue. Infection of metastases was more rapid and intense than primary tumors, achieving isotope uptake within about threefold the efficiency of the thyroid. Virotherapy combined with systemic (131)I resulted in more rapid disease regression than either therapy alone. In addition to ubiquitous CD46, vaccine MV retains cell entry through its immune cell-specific receptor signaling lymphocytic activation molecule (SLAM). We asked whether both receptors could sustain effective oncolysis of MCL. Strikingly, only SLAM-dependent entry sustained efficient viral spread, tumor regression, and prolonged survival. These observations shift the focus of future clinical trials to SLAM-expressing hematologic malignancies and suggest that oncolytic vectors may depend on tissue-specific receptors for both cell entry and activation of responses assisting their replication.

Abstract
The ubiquitin-proteasome system (UPS) and associated signaling pathways are regarded today as an exciting area of development for novel therapeutics. However, two decades ago, following the discovery and elucidation of ubiquitin and the 26S proteasome as key mediators of protein turnover, the concept of inhibiting the UPS was not even considered a feasible therapeutic approach due to the assumption that inhibition of this pathway would have widespread deleterious effects. Subsequent clinical developments with the first-in-class proteasome inhibitor bortezomib have radically overturned that view, with the proteasome now recognized as a validated target and proteasome inhibition demonstrated to be a highly successful treatment for a number of hematologic malignancies. Here we provide a historic perspective on the emergence of proteasome inhibition, sharing some of the lessons learned along the way. We describe the development of bortezomib and the elucidation of the effects of its novel mechanism of action, and place the cutting-edge work described elsewhere in this issue in the context of these historic developments.

Abstract
To complement the existing treatment guidelines for all tumour types, ESMO organizes consensus conferences to focus on specific issues in each type of tumour. In this setting, a consensus conference on the management of lymphoma was held on 18 June 2011 in Lugano, next to the 11th International Conference on Malignant Lymphoma. The conference convened ∼30 experts from all around Europe, and selected six lymphoma entities to be addressed; for each of them, three to five open questions were to be addressed by the experts. For each question, a recommendation should be given by the panel, referring to the strength of the recommendation based on the level of evidence. This consensus report focuses on the three less common lymphoproliferative malignancies: marginal zone lymphoma, mantle cell lymphoma, and peripheral T-cell lymphomas. A first report had focused on diffuse large B-cell lymphoma, follicular lymphoma, and chronic lymphocytic leukaemia.

Abstract
Mantle cell lymphoma (MCL) is a type of non-Hodgkin's lymphoma (NHL) with treatment outcomes that have historically been poorer than those observed with other NHL subtypes. Patients typically present with advanced-stage disease and frequent extranodal involvement; the median age at diagnosis is >60 years. Recent improvements in progression-free and overall survival have been observed with more dose-intensive strategies, although at least half of patients diagnosed with MCL are not eligible for such treatment approaches based on age and co-morbidities. In addition, therapy options for relapsed MCL are limited. Only bortezomib is approved for treatment of relapsed MCL in the US. Development of targeted therapy approaches to minimize toxicities while preserving anti-neoplastic properties is of particular importance in MCL. Multiple ongoing studies are attempting to build on the known efficacy of bortezomib by evaluating combination regimens with other targeted agents or cytotoxic chemotherapy. The mammalian target of rapamycin (mTOR) inhibitor temsirolimus has known activity in MCL, making this an attractive class of agents for further investigation in combination regimens. Rituximab and other monoclonal antibodies are being evaluated for novel roles in MCL treatment, including as maintenance therapy. Other classes of drugs being investigated in MCL are immunomodulatory agents, inhibitors of the phosphoinositide 3-kinase/Akt and B-cell receptor signalling pathways, and inhibitors of bcl-2 and histone deacetylase. Although many of the agents appear to have modest single-agent activity, the favourable toxicity profile of many agents will make them best suited for incorporation into combination regimens.

Abstract
Mantle cell lymphoma(MCL), a special type of non-Hodgkin's lymphoma, is incurable through conventional treatment. This study aimed to analyze the clinical features, therapeutic responses, and prognosis of patients with MCL. Clinical data of 30 patients with MCL treated in our hospital between April 2006 and July 2011 were analyzed. Eighteen patients were treated with CHOP plus rituximab (R-CHOP) regimen, 12 underwent conventional chemotherapy. The median age of the 30 patients was 58 years, 23 were men, all patients had Cyclin D1 overexpression, 29 (96.7%) had advanced disease, 11 (36.7%) had bone marrow involvement, 9 (30.0%) had gastrointestinal involvement, and 15 (50.0%) had splenomegaly. The complete response(CR) rate and overall response rate(ORR) were significantly higher in patients undergoing R-CHOP immunochemotherapy than in those undergoing conventional chemotherapy (38.9% vs. 16.7%, P = 0.187; 72.2% vs. 41.4%, P = 0.098). The difference of 2-year overall survival rate between the two groups was not significant (P = 0.807) due to the short follow-up time. The 2-year progression-free survival (PFS) rate was higher in R-CHOP group than in conventional chemotherapy group (53% vs. 25%, P = 0.083), and was higher in patients with a lower mantle cell lymphoma international prognostic index (MIPI) (51% for MIPI 0-3, 33% for MIPI 4-5, and 0% for MIPI 6-11, P = 0.059). Most patients with MCL were elderly; in an advanced stage; showed a male predominance; and usually had bone marrow involvement, gastrointestinal involvement, or splenomegaly. R-CHOP regimen could improve the CR rate and ORR of MCL patients. MIPI can be a new prognostic index for predicting the prognosis of advanced MCL.

Abstract
There is no consensus on treatment strategies for elderly patients with mantle cell lymphoma (MCL). In this prospective phase II study we investigated whether the poor outcome could be improved, with reasonable toxicity, by prolonging the immunochemotherapy. Ten cycles of alternating cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP)/cytarabine (AraC) with eight doses of rituximab (R) were given as induction. The potential synergism of intermediate-dose AraC and fludarabine was tested in cycles 6-8. Induction was followed by bimonthly rituximab maintenance for 2 years. The median age of the 60 included patients was 74 years, and the Mantle Cell Lymphoma International Prognostic Index (MIPI) was intermediate or high risk in 98% of the patients. The overall response rate was 95% (complete response/complete response unconfirmed 87%). The response of 11 patients improved with cycles 6-8 (R-fludarabine-AraC). Progression-free survival was 70% and overall survival 72% at 4 years, respectively. Treatment related mortality was 2%. Severe infections were rare, with only one grade 4 infection. More dose reductions were needed during fludarabine-containing courses as compared to R-AraC. In 20 patients a transient grade 4 neutropenia without severe infections was recorded during maintenance. In conclusion, elderly patients with MCL can be treated relatively intensively with acceptable toxicity.

Mantle cell lymphoma (MCL), an aggressive subtype of non-Hodgkin lymphoma, is characterized by the hallmark translocation t(11;14)(q13;q32) and the resulting overexpression of cyclin D1 (CCND1). Our current knowledge of this disease encompasses frequent secondary cytogenetic aberrations and the recurrent mutation of a handful of genes, such as TP53, ATM, and CCND1. However, these findings insufficiently explain the biologic underpinnings of MCL. Here, we performed whole transcriptome sequencing on a discovery cohort of 18 primary tissue MCL samples and 2 cell lines. We found recurrent mutations in NOTCH1, a finding that we confirmed in an extension cohort of 108 clinical samples and 8 cell lines. In total, 12% of clinical samples and 20% of cell lines harbored somatic NOTCH1 coding sequence mutations that clustered in the PEST domain and predominantly consisted of truncating mutations or small frame-shifting indels. NOTCH1 mutations were associated with poor overall survival (P = .003). Furthermore, we showed that inhibition of the NOTCH pathway reduced proliferation and induced apoptosis in 2 MCL cell lines. In summary, we have identified recurrent NOTCH1 mutations that provide the preclinical rationale for therapeutic inhibition of the NOTCH pathway in a subset of patients with MCL.

Abstract
Mantle cell lymphoma (MCL) carries an unfavorable prognosis and requires new treatment strategies. The associated t(11:14) translocation results in enhanced cyclin D1 expression and cyclin D1-dependent kinase activity to promote cell-cycle progression. A pharmacodynamic study of the selective CDK4/6 inhibitor PD0332991 was conducted in 17 patients with relapsed disease, using 2-deoxy-2-[(18)F]fluoro-D-glucose (FDG) and 3-deoxy-3[(18)F]fluorothymidine (FLT) positron emission tomography (PET) to study tumor metabolism and proliferation, respectively, in concert with pre- and on-treatment lymph node biopsies to assess retinoblastoma protein (Rb) phosphorylation and markers of proliferation and apoptosis. Substantial reductions in the summed FLT-PET maximal standard uptake value (SUV(max)), as well as in Rb phosphorylation and Ki-67 expression, occurred after 3 weeks in most patients, with significant correlations among these end points. Five patients achieved progression-free survival time of > 1 year (range, 14.9-30.1+ months), with 1 complete and 2 partial responses (18% objective response rate; 90% confidence interval, 5%-40%). These patients demonstrated > 70%, > 90%, and ≥ 87.5% reductions in summed FLT SUV(max) and expression of phospho-Rb and Ki67, respectively, parameters necessary but not sufficient for long-term disease control. The results of the present study confirm CDK4/6 inhibition by PD0332991 at a well-tolerated dose and schedule and suggest clinical benefit in a subset of MCL patients. This study is registered at www.clinicaltrials.gov under identifier NCT00420056.

Abstract
PURPOSE Aurora A and B are oncogenic serine/threonine kinases that regulate mitosis. Overexpression of Auroras promotes resistance to microtubule-targeted agents. We investigated mechanistic synergy by inhibiting the mitotic spindle apparatus in the presence of MLN8237 [M], an Aurora A inhibitor with either vincristine [MV] or docetaxel [MD] in aggressive B-cell non-Hodgkin lymphoma (B-NHL). The addition of rituximab [R] to MV or MD was evaluated for synthetic lethality. EXPERIMENTAL DESIGN Aggressive B-NHL cell subtypes were evaluated in vitro and in vivo for target modulation and anti-NHL activity with single agents, doublets, and triplets by analyzing cell proliferation, apoptosis, tumor growth, survival, and mechanisms of response/relapse by gene expression profiling with protein validation. RESULTS MV is synergistic whereas MD is additive for cell proliferation inhibition in B-NHL cell culture models. Addition of rituximab to MV is superior to MD, but both significantly induce apoptosis compared with doublet therapy. Mouse xenograft models of mantle cell lymphoma showed modest single-agent activity for MLN8237, rituximab, docetaxel, and vincristine with tumor growth inhibition (TGI) of approximately 10% to 15%. Of the doublets, MV caused tumor regression, whereas TGI was observed with MD (approximately 55%-60%) and MR (approximately 25%-50%), respectively. Although MV caused tumor regression, mice relapsed 20 days after stopping therapy. In contrast, MVR was curative, whereas MDR led to TGI of approximately 85%. Proliferation cell nuclear antigen, Aurora B, cyclin B1, cyclin D1, and Bcl-2 proteins of harvested tumors confirmed response and resistance to therapy. CONCLUSIONS Addition of rituximab to MV is a novel therapeutic strategy for aggressive B-NHL and warrants clinical trial evaluation.

Abstract
PURPOSE Dysregulated cyclin-dependent kinases are important to the growth of some sarcomas. Flavopiridol is a pan-CDK inhibitor that has been shown to potentiate chemotherapy. As such, we explored the potentiation of doxorubicin by flavopiridol in sarcoma, in vitro and in vivo, and conducted a phase I trial of flavopiridol with doxorubicin in patients with advanced sarcomas. EXPERIMENTAL DESIGN Sarcoma cell lines and xenografts were treated with flavopiridol alone and in combination with doxorubicin. In the phase I study, doxorubicin and flavopiridol were administered on two flavopiridol schedules; a 1-hour bolus and split dosing as a 30-minute bolus followed by a 4-hour infusion. RESULTS Preclinically, flavopiridol potentiated doxorubicin. In vivo, doxorubicin administered 1 hour before flavopiridol was more active than doxorubicin alone. Clinically, 31 patients were enrolled on protocol and flavopiridol was escalated to target dose in two schedules (90 mg/m(2) bolus; 50 mg/m(2) bolus + 40 mg/m(2) infusion) both in combination with doxorubicin (60 mg/m(2)). Dose-limiting toxicities were neutropenia, leukopenia, and febrile neutropenia but no maximum tolerated dose was defined. Flavopiridol pharmacokinetics showed increasing C(max) with increasing dose. Response Evaluation Criteria in Solid Tumors (RECIST) responses included two partial responses, however, stable disease was seen in 16 patients. Of 12 evaluable patients with progressive well- and dedifferentiated liposarcoma, eight had stable disease greater than 12 weeks. CONCLUSIONS The sequential combination of doxorubicin followed by flavopiridol is well tolerated on both schedules. Disease control was observed in well- and dedifferentiated liposarcoma specifically, a disease in which CDK4 is known to be amplified.

Calcium blockers decrease the bortezomib resistance in mantle cell lymphoma via manipulation of tissue transglutaminase activities. Blood 2012; 119:2568-78.

Abstract
Although bortezomib is clinically approved for the treatment of mantle cell lymphoma (MCL), only limited effects of this treatment have been demonstrated. To improve survival for bortezomib-resistant patients, it is necessary to develop new therapeutic strategies. In the present study, we used biochemical and molecular methodologies to demonstrate that tissue transglutaminase (TG) activates downstream NF-κB signaling pathways. The signaling axis from TG to NF-κB could be a new therapeutic target to overcome bortezomib resistance in MCL. TG2 is a calcium-dependent protein cross-linking enzyme reported to be overexpressed in various cancer cells. We found that MCL cells expressed elevated levels of TG2 and that the modification of TG2 activities altered NF-κB expression and downstream signaling in MCL cells. When TG2 signaling was inhibited by calcium blockers, the combination of a calcium blocker (perillyl alcohol) with bortezomib suppressed NF-κB expression and improved the cytotoxicity of bortezomib in MCL cells. Our study is the first to show the expression of TG2 and the contribution of TG2 to NF-κB signaling in MCL. TG2 inhibition may be used as an alternative target anti-MCL therapy, and calcium blockers may be combined with bortezomib to overcome the bortezomib resistance in MCL.

Abstract
Antimetabolites are cytotoxic agents, which have been developed for more than 50 years. Which cancer patient did not receive or will not receive 5-fluorouracil or methotrexate during the evolution his or her disease? Antimetabolites are defined as interfering with the synthesis of the DNA constituents; they are structural analogues, either of purine and pyrimidine bases (or the corresponding nucleosides), or of folate cofactors, which are involved at several steps of purine and pyrimidine biosynthesis. Their first mechanism of action is, therefore, to induce depletion in nucleotides inducing in turn an inhibition of DNA replication. However, some of them are able to get inserted fraudulently into nucleic acids, inducing structural abnormalities leading to cell death by other mechanisms, including DNA breaks. We present in this paper, for the three classes of antimetabolites, both ancient and recent molecules as well as molecules still in clinical trials, without exhaustivity.

Abstract
Mantle cell lymphoma (MCL) is a subtype of B-cell Non-Hodgkin's Lymphoma (NHL) and accounts for approximately 6% of all lymphomas. Unlike small lymphocytic lymphoma and chronic lymphocytic lymphoma, which are relatively sensitive to chemotherapy, MCL is highly refractory to most chemotherapy, and has the worst survival rate among NHL patients. Stem-like cells in MCL, which we have termed mantle cell lymphoma-initiating cells (MCL-ICs), enriched in the population that are lack of prototypic B-cell marker CD19. These cells were able to self-renew upon serial transplantation and are highly tumorigenic. Importantly, these stem-like cells confer chemotherapeutic resistance to MCL. In this report, we show that stem-like MCL-ICs are resistant to bortezomib, as well as chemotherapeutic regimens containing bortezomib, despite constitutive nuclear factor-κB (NF-κB) expression. Interestingly, bortezomib treatment induced MCL-IC differentiation in plasma-like cells with upregulated expression of CD38 and CD138. This process was accompanied by expression of plasma cell differentiation transcriptional factors, BLIMP-1 and IRF4. This article is the first to show that stem-like MCL cells utilize constitutive NF-κB expression for survival. Given that the NF-κB expression in MCL-ICs is resistant to bortezomib, it will be important to find alternative therapeutic strategies to inhibit NF-κB expression.

Abstract
Mantle cell lymphoma (MCL) usually responds well to initial therapy but is prone to relapses with chemoresistant disease, indicating the need for novel therapeutic approaches. Inhibition of the p53 E3 ligase human homolog of the murine double minute protein-2 (HDM-2) with MI-63 has been validated as one such strategy in wild-type (wt) p53 models, and our genomic and proteomic analyses demonstrated that MI-63 suppressed the expression of the ribonucleotide reductase (RNR) subunit M2 (RRM2). This effect occurred in association with induction of p21 and cell-cycle arrest at G(1)/S and prompted us to examine combinations with the RNR inhibitor 2',2'-difluoro-2'-deoxycytidine (gemcitabine). The regimen of MI-63-gemcitabine induced enhanced, synergistic antiproliferative, and proapoptotic effects in wtp53 MCL cell lines. Addition of exogenous dNTPs reversed this effect, whereas shRNA-mediated inhibition of RRM2 was sufficient to induce synergy with gemcitabine. Combination therapy of MCL murine xenografts with gemcitabine and MI-219, the in vivo analog of MI-63, resulted in enhanced antitumor activity. Finally, synergy was seen with MI-63-gemcitabine in primary patient samples that were found to express high levels of RRM2 compared with MCL cell lines. These findings provide a framework for translation of the rational combination of an HDM-2 and RNR inhibitor to the clinic for patients with relapsed wtp53 MCL.
