Thalidomide enhanced the efficacy of CHOP chemotherapy in the treatment of diffuse large B cell lymphoma: A phase II study.

ABSTRACT: Cyclophosphamide, doxorubicin, vincristine, and prednisolone plus rituximab (R-CHOP) is the standard treatment for patients with diffuse large B cell lymphoma (DLBCL). However, rituximab cannot be popularly applied in a considerable number of patients with DLBCL because of economic reasons. To develop a new regimen to improve the outcome of these patients is extremely important. In our study, sixty five patients with DLBCL were randomly assigned to thalidomide plus CHOP group (n=32) or to CHOP alone group (n=33). Objective response rates (ORR) and complete remission rates (CRR) were 96.7% and 80.6% in T-CHOP group versus 78.9 % and 57.8 % in CHOP group, respectively (P <0.05). At a median follow-up of 96 months, median PFS for T-CHOP group was still not reached yet, and in CHOP group it was 22.9 months (95% CI [0-50.4]). (P=0.163). Median overall survival (OS) for T-CHOP group was also not reached, and the estimated median OS for CHOP group was 83.5 months, the difference of OS between the two groups is not significant (p=0.263). But, in patients with Bcl-2 positive and Bcl-6 negative, the median PFS in T-CHOP group was longer than that in CHOP group (111.0 vs 8.5 months (P=0.017). In addition, thalidomide did not significantly increase the grade 3/4 toxicity of CHOP. We concluded that the addition of thalidomide to the CHOP regimen significantly improved the CRR and showed a trend of improving clinical outcome in patients with DLBCL, especially for patients with Bcl-2 positive and Bcl-6 negative B-cell phenotype, without increased toxicity.

Phase II Study of Bendamustine and Ofatumumab in Elderly Patients with Newly Diagnosed Diffuse Large B-Cell Lymphoma Who Are Poor Candidates for R-CHOP Chemotherapy.

Project description:Lessons learnedThe combination of ofatumumab and bendamustine in elderly patients with diffuse large B-cell lymphoma demonstrated modest efficacy compared with standard of care.The poor response may have been due to patient age and the high rate of treatment discontinuation.BackgroundThis phase II trial evaluated the efficacy of bendamustine and ofatumumab in elderly patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) who were not candidates for rituximab cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP).MethodsPatients received IV 90 mg/m2 bendamustine on days 1 and 2 of cycles 1 through 6 and IV 1,000 mg ofatumumab on days 1 and 8 of cycle 1 and on day 1 of cycles 2 through 6. Both drugs were administered at the U.S. Food and Drug Administration-approved dose for combination therapy. All patients received premedications before each infusion of ofatumumab and hematopoietic growth factors. Treatment was administered in 21-day cycles, with restaging after cycle 3 and cycle 6. The primary endpoint was complete response rate (CRR).ResultsTwelve of 21 enrolled patients completed treatment; median age was 83 years. The most common reasons for treatment discontinuation were disease progression (three patients), intercurrent illness (two patients), and death (one patient due to drug-related sepsis and bowel necrosis and one patient due to unknown cause). Thrombocytopenia (14%), neutropenia (10%), diarrhea (10%), vomiting (10%), and dehydration (10%) were the most common grade ≥3 treatment-related adverse events. The overall response rate was 90.5% and the CRR was 33.3%. Median progression-free survival (PFS) and overall survival (OS) were 8.6 and 12.0 months, respectively.ConclusionThe combination of ofatumumab and bendamustine is feasible in elderly patients with DLBCL.

Clinical efficacy and molecular biomarkers in a phase II study of tucidinostat plus R-CHOP in elderly patients with newly diagnosed diffuse large B-cell lymphoma.

Project description:BackgroundElderly patients with diffuse large B-cell lymphoma (DLBCL) present with poor clinical outcome and intolerance to intensive chemotherapy. Histone deacetylase inhibitors (HDACIs) show anti-lymphoma activities and can be applied to treat DLBCL. This study aimed to evaluate efficacy and safety of oral HDACI tucidinostat (formerly known as chidamide) plus R-CHOP (CR-CHOP) in elderly patients with newly diagnosed DLBCL (International Prognostic Index ≥ 2).ResultsAmong 49 patients, the complete response rate was 86%, with overall response rate achieving 94%. The 2-year progression survival (PFS) and overall survival (OS) rates were 68% (95% CI 52-79) and 83% (95% CI 68-91). Comparing with historical control (NCT01852435), the 2-year PFS and OS rates of double-expressor lymphoma phenotype (DEL) were improved, and negative prognostic effect of histone acetyltransferases CREBBP/EP300 mutations was also mitigated by CR-CHOP. Grade 3-4 neutropenia was reported in 171, grade 3-4 thrombocytopenia in 27, and grade 3 anemia in 11 of 283 cycles. No grade 4 non-hematological adverse event was reported.ConclusionCR-CHOP is effective and safe in elderly patients with newly diagnosed DLBCL. Relevance of DEL phenotype and molecular biomarkers on CR-CHOP response warrants further investigation in DLBCL. Trial registration ClinicalTrial.gov, NCT02753647. Registered on April 28, 2016.

Pegylated liposomal doxorubicin replacing conventional doxorubicin in standard R-CHOP chemotherapy for elderly patients with diffuse large B-cell lymphoma: an open label, single arm, phase II trial.

Project description:The present multicenter phase II trial evaluated the safety and efficacy of pegylated liposomal doxorubicin (PLD) instead of conventional doxorubicin in standard R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine [Oncovin], and prednisone) therapy for elderly patients with diffuse large B-cell lymphoma.Patients aged > 60 years who had stage II to IV disease were included. Treatment consisted of rituximab 375 mg/m(2) intravenously (I.V.); cyclophosphamide 750 mg/m(2) IV; PLD 40 mg/m(2) (maximum, 90 mg) I.V. over 1 hour; and vincristine 2.0 mg I.V., all on day 1. Additionally prednisone, 40 mg/m(2), was given orally on days 1 to 1 to 5 (DRCOP [rituximab, cyclophosphamide, PLD, vincristine, and prednisone]). The cycles were repeated every 3 weeks for 6 to 8 cycles.Eighty patients were enrolled and were evaluable for toxicity. The median age was 69 years. All except 1 had additional cardiac risk factors for anthracycline-induced cardiac toxicity beyond advanced age. From the intent-to-treat analysis of 79 eligible patients, the overall response rate was 86%, and the complete response rate was 78%. Cardiac events greater than grade 3 were identified in 3 patients (4%); grade 1 to 2 events, mostly asymptomatic declines in ejection fraction, were noted in another 16 patients. One death was attributed to cardiac failure. The estimated 5-year event-free and overall survival rate was 52% and 70%, respectively.DRCOP represents an effective strategy for potentially mitigating cardiotoxicity in elderly patients with aggressive B-cell lymphoma. Future studies incorporating baseline cardiac risk assessments, long-term follow-up data, and biospecimen collection for correlative science should be undertaken.

Identification of gene modules associated with survival of diffuse large B-cell lymphoma treated with CHOP-based chemotherapy.

Project description:Diffuse Large B-cell Lymphoma (DLBCL), a heterogeneous disease, is influenced by complex network of gene interactions. Most previous studies focused on individual genes, but ignored the importance of intergenic correlations. In current study, we aimed to explore the association between gene networks and overall survival (OS) of DLBCL patients treated with CHOP-based chemotherapy (cyclophosphamide combination with doxorubicin, vincristine and prednisone). Weighted gene co-expression network analysis was conducted to obtain insights into the molecular characteristics of DLBCL. Ten co-expression gene networks (modules) were identified in training dataset (n = 470), and their associations with patients' OS after chemotherapy were tested. The results were validated in four independent datasets (n = 802). Gene ontology (GO) biological function enrichment analysis was conducted with Metascape. Three modules (purple, brown and red), which were enriched in T-cell immune, cell-cell adhesion and extracellular matrix (ECM), respectively, were found to be related to longer OS. Higher expression of several hub genes within these three co-expression modules, for example, LCP2 (HR = 0.77, p = 5.40 × 10-2), CD2 (HR = 0.87, p = 6.31 × 10-2), CD3D (HR = 0.83, p = 6.94 × 10-3), FYB (HR = 0.82, p = 1.40 × 10-2), GZMK (HR = 0.92, p = 1.19 × 10-1), FN1 (HR = 0.88, p = 7.06 × 10-2), SPARC (HR = 0.82, p = 2.06 × 10-2), were found to be associated with favourable survival. Moreover, the associations of the modules and hub genes with OS in different molecular subtypes and different chemotherapy groups were also revealed. In general, our research revealed the key gene modules and several hub genes were upregulated correlated with good survival of DLBCL patients, which might provide potential therapeutic targets for future clinical research.

Diffuse large B-cell lymphoma: R-CHOP failure-what to do?

Project description:Although rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) is the standard treatment for patients with diffuse large B-cell lymphoma (DLBCL), ?30% to 50% of patients are not cured by this treatment, depending on disease stage or prognostic index. Among patients for whom R-CHOP therapy fails, 20% suffer from primary refractory disease (progress during or right after treatment) whereas 30% relapse after achieving complete remission (CR). Currently, there is no good definition enabling us to identify these 2 groups upon diagnosis. Most of the refractory patients exhibit double-hit lymphoma (MYC-BCL2 rearrangement) or double-protein-expression lymphoma (MYC-BCL2 hyperexpression) which have a more aggressive clinical picture. New strategies are currently being explored to obtain better CR rates and fewer relapses. Although young relapsing patients are treated with high-dose therapy followed by autologous transplant, there is an unmet need for better salvage regimens in this setting. To prevent relapse, maintenance therapy with immunomodulatory agents such as lenalidomide is currently undergoing investigation. New drugs will most likely be introduced over the next few years and will probably be different for relapsing and refractory patients.

The Gut Microbiome Correlated to Chemotherapy Efficacy in Diffuse Large B-Cell Lymphoma Patients.

Project description:The gut microbiome (GMB) has been extensively reported to be associated with the development and prognosis of human diseases. This study aims to investigate the relationship between GMB composition and chemotherapy efficacy in diffuse large B-cell lymphoma (DLBCL). We demonstrated that DLBCL patients at diagnosis have altered GMB compositions. Significant enrichment of the Proteobacteria phylum in DLBCL patients was observed. Gene analysis showed a high abundance of virulence factors genes. We found baseline GMB to be associated with clinical outcomes. The emergence of Lactobacillus fermentum was correlated with better treatment outcome. Our pilot results suggested a correlation between GMB composition and DLBCL development and prognosis. Clues from our study, together with previous research, provided a rational foundation for further investigation on the pathogenesis, prognosis value, and targeted therapy of GMB in DLBCL.

Obinutuzumab plus CHOP is effective and has a tolerable safety profile in previously untreated, advanced diffuse large B-cell lymphoma: the phase II GATHER study.

Project description:This study investigated the safety and efficacy of obinutuzumab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (G-CHOP) in patients with advanced diffuse large B-cell lymphoma (DLBCL) and explored the impact of cell-of-origin (COO) on patient outcomes. Patients (N = 100) received obinutuzumab (1000 mg on the days 1, 8, and 15 of cycle 1, and day 1 of cycles 2-8) plus CHOP (cycles 1-6). For patients without grade ≥3 infusion-related reactions (IRRs) to standard-rate obinutuzumab infusion, a shorter duration of infusion (SDI) was evaluated. Overall and complete response rates, as determined according to the Cheson et al. criteria by investigators/independent radiological facility, were 82.0/75.0% and 55.0/58.0%, respectively. SDI of 120 minutes and 90 minutes were well tolerated with no grade ≥3 IRRs. Among all patients, IRRs typically occurred during cycle 1, day 1. G-CHOP is active and has an acceptable safety profile in the first-line treatment of patients with advanced DLBCL. Clinical Trials: NCT01414855DLBCL.

Differential efficacy of bortezomib plus chemotherapy within molecular subtypes of diffuse large B-cell lymphoma.

Project description:Gene expression profiling of diffuse large B-cell lymphoma (DLBCL) has revealed distinct molecular subtypes that include germinal center B cell-like (GCB) and activated B cell-like (ABC) DLBCL. ABC DLBCL has a worse survival after upfront chemotherapy and is characterized by constitutive activation of the antiapoptotic nuclear factor-kappa B (NF-kappaB) pathway, which can inhibit chemotherapy. We hypothesized that inhibition of NF-kappaB might sensitize ABC but not GCB DLBCL to chemotherapy and improve outcome. As the proteasome inhibitor bortezomib can inhibit NF-kappaB through blocking IkappaBalpha degradation, we investigated bortezomib alone followed by bortezomib and doxorubicin-based chemotherapy in recurrent DLBCL. Tumor tissue was analyzed by gene expression profiling and/or immunohistochemistry to identify molecular DLBCL subtypes. As a control, we showed that relapsed/refractory ABC and GCB DLBCL have equally poor survivals after upfront chemotherapy. Bortezomib alone had no activity in DLBCL, but when combined with chemotherapy, it demonstrated a significantly higher response (83% vs 13%; P < .001) and median overall survival (10.8 vs 3.4 months; P = .003) in ABC compared with GCB DLBCL, respectively. These results suggest bortezomib enhances the activity of chemotherapy in ABC but not GCB DLBCL, and provide a rational therapeutic approach based on genetically distinct DLBCL subtypes. This trial is registered with http://www.ClinicalTrials.gov under identifier NCT00057902.

ROBUST: Lenalidomide-R-CHOP versus placebo-R-CHOP in previously untreated ABC-type diffuse large B-cell lymphoma.

Project description:Activated B-cell-like (ABC) diffuse large B-cell lymphoma (DLBCL), the major constituent of nongerminal center B-cell-like (non-GCB) DLBCL, is associated with poorer survival outcomes than GCB-type DLBCL. In Phase II studies, lenalidomide combined with R-CHOP (R(2)-CHOP) improved outcomes relative to historical R-CHOP in newly diagnosed DLBCL, particularly in non-GCB cases. ROBUST (CC-5013-DLC-002) is a randomized, double-blind, global, Phase III study of oral lenalidomide (15 mg, days 1-14) plus R-CHOP21 × 6 versus placebo-R-CHOP21 × 6 in patients with previously untreated ABC-type DLBCL. Subtyping is done within 3 calendar days by central laboratory gene-expression profiling of formalin-fixed paraffin-embedded biopsy tissue. The primary end point is progression-free survival. Secondary end points include response rates, overall survival and health-related quality of life.

Impact of sarcopenia on treatment tolerance in United States veterans with diffuse large B-cell lymphoma treated with CHOP-based chemotherapy.

Project description:While sarcopenia has been associated with decreased overall survival in diffuse large B-cell (DLBCL) patients, the impact of sarcopenia on treatment tolerance has not been well-studied. We evaluated the association of sarcopenia with febrile neutropenia hospitalization, treatment-related mortality, and ability to complete standard number of cycles in a retrospective cohort of United States veterans diagnosed with DLBCL between 1998 and 2008 and treated with cyclophosphamide, doxorubicin, vincristine, and prednisone, with or without rituximab. Baseline body composition parameters were evaluated using computed tomography analysis. In total, 522 patients were included in the study, of whom 245 (47%) had baseline sarcopenia. After controlling for other variables, baseline sarcopenia was independently associated with increased risk of febrile neutropenia hospitalization (adjusted Odds Ratio (aOR) 1.64, 95% confidence interval (CI) 1.01-2.65) and inability to complete standard number of treatment cycles (aOR 1.49, 95% CI 1.02-2.16) compared with no baseline sarcopenia. There was a non-statistically significant trend toward higher treatment-related mortality in sarcopenic patients than non-sarcopenic patients (aOR 1.77, 95% CI 0.92-3.41). Sarcopenia is associated with increased risk of treatment intolerance and may be useful in guiding treatment planning and supportive care measures. Am. J.
