A multicenter phase II trial of etoposide, methylprednisolone, high-dose cytarabine, and oxaliplatin for patients with primary refractory/relapsed aggressive non-Hodgkin’s lymphoma

Optimized BEAC conditioning regimen improves clinical outcomes of autologous hematopoietic stem cell transplantation in non-Hodgkin lymphomas

The conditioning regimen is an important part of autologous hematopoietic stem cell transplantation (ASCT). We explored the efficacy and safety of an optimized BEAC (adjusted-dose, intermediate-dose cytarabine and reduced-dose cyclophosphamide, AD-BEAC) conditioning regimen for non-Hodgkin lymphoma (NHL). A total of 141 NHL patients received AD-BEAC or a standard-dose BEAC (SD-BEAC) conditioning regimen from January 2007 to December 2017, and 104 patients were included in the study after 1:1 propensity matching. The 5-year overall survival (OS) and progression free survival (PFS) rates were significantly higher with AD-BEAC than with SD-BEAC (82.7% vs. 67.3%, P = 0.039; 76.9% vs. 57.7%, P = 0.039). Transplant-related mortality (TRM) was 3.8% in both the AD-BEAC and SD-BEAC groups. The AD-BEAC group had lower incidence of oral ulcers and cardiotoxicity than the SD-BEAC group. An optimized BEAC conditioning regimen is an effective conditioning regimen for ASCT in NHL with acceptable toxicity, that is more effective and safer than a standard BEAC conditioning regimen.

Engineered Artesunate-Naphthalimide Hybrid Dual Drug for Synergistic Multimodal Therapy against Experimental Murine Lymphoma

Lymphoma can effectively be treated with a chemotherapy regimen that is associated with adverse side effects due to increasing drug resistance, so there is an emergent need for alternative small-molecule inhibitors to overcome the resistance that occurs in lymphoma management and overall increase the prognosis rate. A new series of substituted naphthalimide moieties conjugated via ester and amide linkages with artesunate were designed, synthesized, and characterized. In addition to the conjugates, to further achieve a theranostic molecule, FITC was incorporated via a multistep synthesis process. DNA binding studies of these selected derivatives by ultraviolet-visible (UV-vis), fluorescence spectroscopy, intercalating dye (EtBr, acridine orange)-DNA competitive assay, and minor groove binding dye Hoechst 33342-DNA competitive assay suggested that the synthesized novel molecules intercalated between the two strands of DNA due to its naphthalimide moiety and its counterpart artesunate binds with the minor groove of DNA. Napthalimide-artesunate conjugates inhibit the growth of lymphoma and induce apoptosis, including ready incorporation and reduction in cell viability. The remodeled drug has a significant tumoricidal effect against solid DL tumors developed in BALB/c mice in a dose-dependent manner. The novel drug appears to inhibit metastasis and increase the survival of the treated animals compared with untreated littermates.

A phase II study of etoposide, methylprednisolone, high-dose cytarabine, and oxaliplatin (ESHAOx) for patients with refractory or relapsed Hodgkin's lymphoma

We assessed the efficacy and toxicity of etoposide, methylprednisolone, high-dose cytarabine, and oxaliplatin (ESHAOx) combination chemotherapy in patients with refractory or relapsed Hodgkin's lymphoma (HL). This was an open-label, non-randomized, multi-center phase II study. The ESHAOx regimen consisted of intravenous (i.v.) etoposide 40 mg/m² on days 1 to 4, i.v. methylprednisolone 500 mg on days 1 to 5, i.v. cytarabine 2 g/m² on day 5, and i.v. oxaliplatin 130 mg/m² on day 1. Cycles (up to six) were repeated every 3 weeks. In an effort to identify prognostic markers, the serum levels of cytokines including tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and vascular endothelial growth factor (VEGF) were measured at the time of study entry. A total of 37 patients were enrolled, and 36 were available for evaluation of tumor response. The overall response rate was 72.2% (26/36) (complete response, 33.3% [12/36]; partial response, 38.9% [14/36]). The median time to progression was 34.9 months (95% confidence interval, 23.1-46.7 months). The most common grade 3 or 4 hematological adverse events were neutropenia (16/37, 43.2%), followed by thrombocytopenia (10/37, 27.0%). Grade 3 or 4 non-hematological adverse events were nausea (3/37, 8.1%), anorexia (2/37, 5.4%), mucositis (1/37, 2.7%), and skin rash (1/37, 2.7%). There were no treatment-related deaths. High levels of TNF-α and CRP were significantly associated with poorer overall survival (p = 0.00005 for TNF-α, p = 0.0004 for CRP, respectively). The ESHAOx regimen exhibited antitumor activity and an acceptable safety profile in patients with refractory or relapsed HL. Trial Registration: ClinicalTrials.gov.

Long-term follow-up of chemoimmunotherapy with rituximab, oxaliplatin, cytosine arabinoside, dexamethasone (ROAD) in patients with relapsed CD20+ B-cell non-Hodgkin lymphoma: Results of a study of the Mayo Clinic Cancer Center Research Consortium (MCCRC) MC0485 now known as academic and community cancer research united (ACCRU)

Patients with relapsed aggressive non-Hodgkin lymphoma (NHL) are often treated with platinum-based chemoimmunotherapy regimens in preparation for autologous stem cell transplant. We sought to reduce toxicity and maintain efficacy by using oxaliplatin with rituximab, cytarabine and dexamethasone (ROAD) in a phase II clinical trial in patients who had relapsed after one prior regimen. ROAD was delivered q21 days and consisted of rituximab 375 mg/m² IV weekly x 4 doses (cycle 1 only); dexamethasone 40 mg PO/IV d2 - 5; oxaliplatin 130 mg/m² IV day 2; cytarabine 2000 mg/m² IV × two doses on days 2 to 3; and pegfilgrastim 6 mg SC on day 4. Forty-five eligible patients were accrued between 2006 and 2008. Patient characteristics were a median age of 69 years; 96% had received prior rituximab; 53% were within one year of diagnosis. The median number of cycles received was 2 (range, 1-6). Forty-four % received ROAD as an outpatient. The overall response rate was 71% with 27% (12/45) CR and 44% (20/45) PR. Forty-four % (20/45) of all patients and 69% (18/26) of patients whom responded after 2 cycles proceeded to transplant. Median overall survival was 26 mos (95% CI: 7.3 mos-not reached) and median progression-free survival was 11 mos (95% CI: 6-104 mos). There was no grade 3/4 nephrotoxicity; the rate of grade 3/4 neuropathy was 4%. Forty-two percent of all patients and 69% of patients transplanted remain alive at 5 years. ROAD represents an acceptable salvage therapeutic option for patients with relapsed aggressive NHL.

Review of the clinical research conducted by the Consortium for Improving Survival of Lymphoma of the Korean Society of Hematology Lymphoma Working Party

The Consortium for Improving Survival of Lymphoma (CISL) in Korean Society of Hematology Lymphoma Working Party had first meeting in February, 2006 with 10 institutions and 12 members. Now CISL comprised of 64 centers. CISL has concentrated research activity on lymphomas which are relatively frequent in Korea and has tried to give favors for the Korean lymphoma patients. CISL has conducted more than 30 retrospective studies to evaluate Korean peculiar lymphoma subtypes. More than 30 prospective trials have been being performed for diffuse large B-cell lymphoma, marginal zone lymphoma, extra-nodal NK/T-cell lymphoma, and so on. The first prospective trial for advanced marginal zone lymphoma has led to use Rituximab containing chemotherapy with the re-imbursement of health insurance in Korea. The multi-center trials of the CISL with new therapeutic modalities will improve further the survival of lymphoma patients not only quantitatively but also qualitatively.
