Health resource utilization and costs of care for adult patients with relapsed or refractory mantle cell lymphoma in the United States: a retrospective claims analysis. Expert Rev Pharmacoecon Outcomes Res 2023; 23:773-787. [PMID: 37278284 DOI: 10.1080/14737167.2023.2216458] [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: 03/24/2023] [Accepted: 05/05/2023] [Indexed: 06/07/2023]
Abstract
OBJECTIVES We assessed real-world healthcare resource utilization (HRU) and costs among US patients with relapsed or refractory mantle cell lymphoma (R/R MCL) by line of therapy (LoT). METHODS We selected patients from MarketScan® (1/1/2016-12/31/2020): ≥1 claims of MCL-indicated first line (1L) therapies, ≥1 diagnoses of MCL pre-index date (1L initiation date), ≥6-month continuous enrollment pre-index date, second line (2L) therapy initiation, ≥18 years old at 2L, and no clinical trial enrollment. Outcomes included time to next treatment (TTNT), all-cause HRU, and costs. RESULTS The cohort (N = 142) was 77.5% male, aged 62 years (median). Sixty-six percent and 23% advanced to 3L and 4L+, respectively. Mean (median) TTNT was 9.7 (5.9), 9.3 (5.0), and 6.3 (4.2) months for 2L, 3L, and 4L+, respectively. Mean (median) per patient per month (PPPM) costs were $29,999 ($21,313), $29,352 ($20,033), and $30,633 ($23,662) for 2L, 3L, and 4L+, respectively. Among those who received Bruton tyrosine kinase inhibitors, mean (median) PPPM costs were $24,702 ($17,203), $31,801 ($20,363), and $36,710 ($25,899) for 2L, 3L, and 4L+, respectively. CONCLUSIONS During the period ending in 2020, patients relapsed frequently, incurring high HRU and costs across LoTs. More effective treatments with long-lasting remissions in R/R MCL may reduce healthcare burden.

Abstract
Mantle cell lymphoma (MCL) is an aggressive lymphoid malignancy with a poor prognosis. Ubiquitin-specific peptidase 9, X-linked (USP9X), has been associated with multiple physiological pathways and regulates various cellular activities. In this study, we explored the role of USP9X in MCL in vitro and in vivo. USP9X was verified to be increased in peripheral blood mononuclear cells (PBMCs) of MCL patients and MCL cells. Moreover, CCND1 and SOX11 were also upregulated in PBMCs of MCL patients. The positive correlation between USP9X and CCND1, USP9X and SOX11, and CCND1 and SOX11 were identified. Further, USP9X overexpression and knockdown were performed in MCL cells. We proved that USP9X overexpression promoted proliferation and cell cycle and suppressed cell apoptosis in MCL cells. Upregulation of angiogenesis and cell migration were induced by USP9X overexpression in MCL cells. However, the USP9X knockdown showed opposite effects. In addition, USP9X was discovered to decrease Cyclin D1 (CCND1)-mediated SOX11 expression in MCL cells. We demonstrated that SOX11 overexpression reversed USP9X knockdown-mediated angiogenesis in MCL cells. Besides, tumor formation was inhibited by USP9X knockdown in mice in vivo. In conclusion, these results revealed that USP9X promoted tumor angiogenesis in MCL via increasing CCND1-mediated SOX11.

Abstract
Maternal embryonic leucine zipper kinase (MELK) is of vital importance due to its significant role in cancer development and its association with poor prognosis in different cancers. Here, we employed several computer aided drug design approaches to shortlist potential binding molecules of MELK. For virtual screening, asinex oncology library (containing 6334 drugs) and comprehensive marine natural products database (containing approximately 32,000 drugs) were used. The study identified two drug molecules: Top-2 and Top-3 as high affinity binding MELK molecules compared to the control co-crystalized Top-1 inhibitor. Both the shortlisted compounds and the control showed high stable binding free energy and high GOLD score. The compounds and control also reported stable dynamics with root mean square deviations (RMSD) value ∼ 2 Å in 500 ns. Similarly, the MELK active site residues were observed in good stability with the compounds. Further, it was noticed the compounds/control formed multiple hydrogen bonds with the MELK active pocket residues which is the main reason of high intermolecular stability. Atomic level binding free energies determined van der Waals and electrostatic energies to play vital role in stable complex formation. From drug likeness and pharmacokinetics perspective, the compounds are ideal molecules for further investigation. Overall, the results are promising and might be tested in in vivo and in vitro studies against MELK.

Abstract
One of the most common cancer malignancies is non-Hodgkin lymphoma, whose incidence is nearly 3% of all 36 cancers combined. It is the fourth highest cancer occurrence in children and accounts for 7% of cancers in patients under 20 years of age. Today, the survivability of individuals diagnosed with non-Hodgkin lymphoma varies by about 70%. Chemotherapy, radiation, stem cell transplantation, and immunotherapy have been the main methods of treatment, which have improved outcomes for many oncological patients. However, there is still the need for creation of novel medications for those who are treatment resistant. Additionally, more effective drugs are necessary. This review gathers the latest findings on non-Hodgkin lymphoma treatment options for pediatric patients. Attention will be focused on the most prominent therapies such as monoclonal antibodies, antibody–drug conjugates, chimeric antigen receptor T cell therapy and others.

Abstract
OPINION STATEMENT Mantle cell lymphoma is a rare and incurable non-Hodgkin lymphoma with a heterogenous clinical presentation. Typically, treatment consists of frontline chemoimmunotherapy induction with or without autologous stem cell transplant (ASCT) as consolidation. However, this approach has the propensity to increase short- and long-term toxicities, such as secondary malignancies, without being curative. Genomic profiling of MCL will allow for greater impact of new targeted therapies in the future and may become a helpful tool to guide treatment. Based on the data discussed, use of non-chemotherapy options may become the preferred approach for frontline therapy as opposed to conventional chemotherapy and hematopoietic stem cell transplants.

Abstract
INTRODUCTION Conventional treatment for mantle cell lymphoma (MCL) patients includes regimens combining rituximab with other cytotoxic drugs, followed or not by consolidation with autologous stem cell transplantation and rituximab maintenance. However, older, unfit, and relapsed/refractory patients are often ineligible for intense treatment. Currently, available new targeted treatment options seem to offer hope in this group of patients. AREAS COVERED This article reviews the safety profiles of new therapeutic chemotherapy-free options for MCL patients. Publications in English from 2010 through June 2020 were surveyed on the MEDLINE database for articles. Proceedings of the American Society of Hematology during the last 5 years were also included. EXPERT OPINION MCL is a clinically heterogenous disease predominantly affecting elderly patients. Its variable clinical course requires personalization and individualization of treatment to achieve optimal survival and acceptable safety profiles, especially in poor prognosis patients. Results of clinical trials performed in the past decade indicated that novel drugs used as a single agent or as part of a conventional chemotherapeutic treatment offer promise in minimalizing the relapse rate for MCL and may allow more effective and safer treatment options by reducing the risk of adverse events, especially cytopenias and infections.

Abstract
Background miR-100 is reported to be associated with cell proliferation and apoptosis. However, the function of miR-100 in mantle cell lymphoma (MCL) is unknown. The purpose of this study is to analyze the abnormal expression of miR-100 and mTOR in MCL together with their potential biological function and pathogenesis. Method Eighteen MCL tissue samples and 3 cell lines (Jeko-1, Mino, Granta-519) were investigated in this research study, while eighteen samples of proliferative lymphadenitis from patients and peripheral lymphocyte cells from healthy volunteers served as controls. The expression and alteration of miR-100 and mTOR mRNA were detected by RT-PCR. The expression and alteration of mTOR protein were explored by Western blot. LV-miR-100-up and LV-mTOR-RNAi were constructed and transfected by lentivirus transfection. Cell proliferation, cell apoptosis and the cell cycle were detected using CCK-8 and flow cytometry. Bioinformatics prediction software was used to predict the miR-100 target gene of mTOR. A double luciferase experiment was used to verify miR-100 targeting at the mTOR-3′-UTR. The interaction between miR-100 and mTOR was further studied using recovery experiments. GraphPad Prism 7 software (version 7.2) was used for statistical analysis, and a P value < 0.05 was considered statistically significant. Results We found that the expression of miR-100 mRNA in MCL tissues and cell lines was lower, while that of the mTOR protein was higher. There was a negative correlation between miR-100 and mTOR in both MCL tissues and cell lines. Promoting miR-100 and inhibiting mTOR could inhibit cell proliferation, induce cell apoptosis and block the cell cycle in the G1 phase. A double luciferase reporter assay showed that mTOR was one of the target genes of miR-100. The recovery experiment demonstrated that PV-mTOR-up partially set off the effect of LV-miR-100-up on decreasing mTOR expression, inhibiting proliferation, inducing apoptosis and blocking the cell cycle in G1 phase in both Jeko-1 and Mino cells. Conclusions Abnormal expression of miR-100 and mTOR was found in MCL, which included downregulation of miR-100 and upregulation of mTOR. The expression of mTOR is negatively correlated with miR-100. It may play an important role in MCL pathogenesis. miR-100 up-regulation can inhibit cell proliferation, promote cell apoptosis, and inhibit cell cycle in G1 phase by targeting the mTOR gene. miR-100 may potentially be an anti-mantle cell lymphoma gene.

Abstract
AIM AND OBJECTIVE Mantle Cell Lymphoma (MCL) is typically an aggressive and rare disease with poor prognosis, therefore new effective therapeutics are urgently needed. Drug repurposing for cancer treatment is becoming increasingly more attractive as an alternative approach to discover clinically approved drugs that demonstrate antineoplastic effect. The objective of this study was to screen an approved drug library and identify candidate compounds with an antineoplastic effect in MCL cells using High-Throughput Screening (HTS) technique. MATERIALS AND METHODS Using the HTS technique, nearly 3,800 clinically approved drugs and drug candidates were screened in Jeko and Mino MCL cell lines. We also demonstrated the selectivity window of the candidate compounds in six normal cell lines. Further validations were performed in caspase-3/7 apoptosis assay and three-dimensional (3D) multicellular aggregates model using Z138 cell line. RESULTS We identified 98 compounds showing >50% inhibition in either MCL cell line screened, they were distributed across eight unique therapeutic categories and have different mechanisms of action (MOA). We selected alisertib, carfilzomib, pracinostat and YM155 for further validation based on their antiproliferative activity in two MCL cell lines, selectivity to normal cell lines, and drug developing stages in terms of clinical research. Alisertib and carfilzomib showed antiproliferative effect on MCL cell with EC50 = 6 nM and >100-fold selectivity to normal cell lines, especially for alisertib which demonstrated >1000-fold selectivity to 5 out of 6 normal cell lines. Pracinostat and YM155 had potency of 11 and 12 nM in MCL cell with >20-fold selectivity to normal cell lines. All four compounds had been tested in caspase-dependent apoptosis assay. We further validated and demonstrated their anti-MCL effect on cell proliferation and (3D) multicellular aggregates model using Z138 cell line. CONCLUSION This is the first study to examine such a large library of clinically approved compounds for the identification of novel drug candidates for MCL treatment, the results could be rapidly translated into clinical practice in patients with MCL.

Potent efficacy of MCL-1 inhibitor-based therapies in preclinical models of mantle cell lymphoma. Oncogene 2019; 39:2009-2023.

Abstract
Apoptosis-regulating BCL-2 family members, which can promote malignant transformation and resistance to therapy, have become prime therapeutic targets, as illustrated by the striking efficacy in certain lymphoid malignancies of the BCL-2-specific inhibitor venetoclax. In other lymphoid malignancies, however, such as the aggressive mantle cell lymphoma (MCL), cell survival might rely instead or also on BCL-2 relative MCL-1. We have explored MCL-1 as a target for killing MCL cells by both genetic and pharmacologic approaches. In several MCL cell lines, MCL-1 knockout with an inducible CRISPR/Cas9 system triggered spontaneous apoptosis. Accordingly, most MCL cell lines proved sensitive to the specific MCL-1 inhibitor S63845, and MCL-1 inhibition also proved efficacious in an MCL xenograft model. Furthermore, its killing efficacy rose on combination with venetoclax, the BCL-XL-specific inhibitor A-1331852, or Bruton's tyrosine kinase (BTK) inhibitor ibrutinib, which reduced pro-survival signals. We also tested the MCL-1 inhibitor in primary samples from 13 MCL patients, using CD40L-expressing feeder cells to model their microenvironmental support. Notably, all unstimulated primary MCL samples were very sensitive to S63845, but the CD40L stimulation attenuated their sensitivity. Mass cytometric analysis revealed that the stimulation likely conveyed protection by elevating BCL-XL and MCL-1. Accordingly, sensitivity of the CD40L-stimulated cells to S63845 was substantially restored by co-treatment with venetoclax, the BCL-XL-specific inhibitor or ibrutinib. Overall, our findings indicate that MCL-1 is very important for survival of MCL cells and that the MCL-1 inhibitor, both alone and together with ibrutinib, venetoclax or a BCL-XL inhibitor, offers promise for novel improved MCL therapies.

Abstract
Diffuse large B cell lymphoma (DLBCL) and mantle cell lymphoma (MCL) are among the most aggressive B cell non-Hodgkin lymphomas. Maternal embryonic leucine zipper kinase (MELK) plays a role in cancer cell cycle progression and is associated with poor prognosis in several cancer cell types. In this study, the role of MELK in DLBCL and MCL and the therapeutic potential of MELK targeting is evaluated. MELK is highly expressed in DLBCL and MCL patient samples, correlating with a worse clinical outcome in DLBCL. Targeting MELK, using the small molecule OTSSP167, impaired cell growth and survival and induced caspase-mediated apoptosis in the lymphoma cells. Western blot analysis revealed that MELK targeting decreased the phosphorylation of FOXM1 and the protein levels of EZH2 and several mitotic regulators, such as Cdc25B, cyclin B1, Plk-1, and Aurora kinases. In addition, OTSSP167 also sensitized the lymphoma cells to the clinically relevant Bcl-2 inhibitor venetoclax by strongly reducing Mcl1 levels. Finally, OTSSP167 treatment of A20-inoculated mice resulted in a significant prolonged survival. In conclusion, targeting MELK with OTSSP167 induced strong anti-lymphoma activity both in vitro and in vivo. These findings suggest that MELK could be a potential new target in these aggressive B cell malignancies.

Abstract
Background The aggressive B-cell non-Hodgkin lymphomas diffuse large B-cell lymphoma (DLBCL) and mantle cell lymphoma (MCL) are characterised by a high proliferation rate. The anaphase-promoting complex/cyclosome (APC/C) and its co-activators Cdc20 and Cdh1 represent an important checkpoint in mitosis. Here, the role of the APC/C and its co-activators is examined in DLBCL and MCL. Methods The expression and prognostic value of Cdc20 and Cdh1 was investigated using GEP data and immunohistochemistry. Moreover, the therapeutic potential of APC/C targeting was evaluated using the small-molecule inhibitor proTAME and the underlying mechanisms of action were investigated by western blot. Results We demonstrated that Cdc20 is highly expressed in DLBCL and aggressive MCL, correlating with a poor prognosis in DLBCL. ProTAME induced a prolonged metaphase, resulting in accumulation of the APC/C-Cdc20 substrate cyclin B1, inactivation/degradation of Bcl-2 and Bcl-xL and caspase-dependent apoptosis. In addition, proTAME strongly enhanced the anti-lymphoma effect of the clinically relevant agents doxorubicin and venetoclax. Conclusion We identified for the first time APC/C as a new, promising target in DLBCL and MCL. Moreover, we provide evidence that Cdc20 might be a novel, independent prognostic factor in DLBCL and MCL.

Adverse events, resource use, and economic burden associated with mantle cell lymphoma: a real-world assessment of privately insured patients in the United States. Leuk Lymphoma 2019; 60:955-963. [PMID: 30277099 PMCID: PMC7564890 DOI: 10.1080/10428194.2018.1509320] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Revised: 08/02/2018] [Accepted: 08/04/2018] [Indexed: 10/28/2022]
Abstract
In view of recent therapeutic advances in mantle cell lymphoma (MCL), the aim of this retrospective cohort analysis was to assess treatment patterns, adverse events (AEs), resource utilization, and health care costs in patients with MCL in a US-based commercial claims database. A total of 783 patients with MCL (median age = 65 years) were selected. Among patients receiving systemic therapy (n = 457), the most common treatment regimens were bendamustine/rituximab (BR) (41.1%), rituximab/cyclophosphamide/doxorubicin/vincristine (RCHOP) (26.7%), rituximab monotherapy (20.4%), and ibrutinib monotherapy (14.2%). Mean monthly costs during treatments with BR, RCHOP, rituximab, and ibrutinib were $12,958, $24,719, $13,153, and $21,690, respectively. Mean monthly cost during follow-up was $13,650 among patients with ≥6 AEs versus $5131 among those without AEs. The costs of MCL varied considerably by treatment regimen and care setting. The overall economic burden of managing patients with MCL can be substantially affected by costs associated with managing AEs occurring during treatment.

Abstract
Spleen tyrosine kinase (Syk) mediates B‐cell receptor signalling in normal and malignant B cells. Entospletinib is an oral, selective Syk inhibitor. Entospletinib monotherapy was evaluated in a multicentre, phase 2 study of patients with relapsed or refractory indolent non‐Hodgkin lymphoma or mantle cell lymphoma (MCL). Subjects received 800 mg entospletinib twice daily. Forty‐one follicular lymphoma (FL), 17 lymphoplasmacytoid lymphoma/Waldenström macroglobulinaemia (LPL/WM), 17 marginal zone lymphoma (MZL) and 39 MCL patients were evaluated. The primary endpoint was a progression‐free survival (PFS) rate (defined as not experiencing progression or death) at 16 weeks for patients with MCL and at 24 weeks for patients with FL, LPL/WM and MZL. The most common treatment‐emergent adverse events were fatigue, nausea, diarrhoea, vomiting, headache and cough. Common laboratory abnormalities were anaemia, neutropenia and thrombocytopenia; aspartate transaminase, alanine transaminase, total bilirubin and serum creatinine were all increased. PFS at 16 weeks in the MCL cohort was 63·9% [95% confidence interval (CI) 45–77·8%]; PFS at 24 weeks in the FL, LPL/WM, MCL and MZL cohorts was 51·5% (95% CI 32·8–67·4%), 69·8% (95% CI 31·8–89·4%), 56·6% (95% CI 37·5–71·8%) and 46·2% (95% CI 18·5–70·2%), respectively. Entospletinib had limited single‐agent activity with manageable toxicity in these patient populations.

Abstract
BACKGROUND The cell line HaCaT/SM was developed as a sulfur mustard (SM) resistant cell line from the human keratinocyte cell line HaCaT. This cell line was established to learn more about the effect of SM and possible therapeutic approaches to counteract the cytotoxic effects of SM. The aim of this study was to clarify whether the SM-resistant cell line HaCaT/SM exhibit also resistance to other alkylating agents or cytotoxic drugs with different mechanism of action. MATERIAL AND METHOD The chemosensitivity of SM-resistant human keratinocyte cell line HaCaT/SM and the original cell line HaCaT were tested using the XTT assay. Nine cytotoxic drugs from five different substance groups were investigated. RESULTS HaCaT/SM showed a significant increase in resistance against all tested drugs. From the substance class of the alkylating agents, HaCaT/SM showed the strongest resistance increase against chlorambucil (1.7 fold increase). Whereas over all substances strongest increase was observed against cisplatin (5.1 fold increase). DISCUSSION The highest resistance was observed for cisplatin. The SM resistant cells revealed changes in the miRNA profile as described before. The resistance to cisplatin is also connected to a specific miRNA profile. Interestingly, changes of miRNA-203 and miRNA-21 levels were found in HaCaT/SM as well as in cisplatin resistant cells. It is therefore conceivable that the same resistance pathways are involved for both substances.

Abstract
Lymphoma is a large group of lymphoid hematopoietic malignancies including Hodgkin lymphoma and non-Hodgkin's lymphoma. The various subtypes of lymphoma are different in clinical features, response to treatment and prognoses. The relative frequency of specific subtypes of lymphoma varies geographically. The mature T cell lymphoma is much more common in East Asia compared with Western countries. Chemotherapy plays an important role in the treatment of lymphoma. With advances in understanding the biology and genetics of lymphoma, many new agents are used in the treatment of lymphoma. In mainland China, some new agents and new combination chemotherapy regimens showed high efficacy and good tolerability. Chidamide, a histone deacetylase inhibitor, has been approved for the treatment of relapsed or refractory peripheral T cell lymphoma by the China Food and Drug Administration. Anti-programmed death 1 antibodies and chimeric antigen receptor-engineered T cells have been explored for lymphoma immunotherapy in Chinese patients. Advances in the treatment have substantially increased the likelihood of cure for patients with lymphoma.
