Purpose The treatment of patients with diffuse large B-cell lymphoma (DLBCL) with cardiac comorbidity is problematic, because this group may not be able to receive anthracycline-containing chemoimmunotherapy. We designed a single-arm phase II multicenter trial of rituximab, gemcitabine, cyclophosphamide, vincristine, and prednisolone (R-GCVP) in patients considered unfit for anthracycline-containing chemoimmunotherapy because of cardiac comorbidity. Patients and Methods Sixty-one of 62 patients received R-GCVP, administered on day 1 with gemcitabine repeated on day 8 of a 21-day cycle. Median age was 76.5 years. All patients had advanced disease; 27 (43.5%) had left ventricular ejection fraction of ≤ 50%, and 35 (56.5%) had borderline ejection fraction of > 50% and comorbid cardiac risk factors such as ischemic heart disease, diabetes mellitus, or hypertension. Primary end point was overall response rate at the end of treatment. Results Thirty-eight patients (61.3%; 95% CI, 49.2 to 73.4) achieved disease response (complete response [CR], n = 18; undocumented/unconfirmed CR, n = 6; partial response, n = 14). Two-year progression-free survival for all patients was 49.8% (95% CI, 37.3 to 62.3), and 2-year overall survival was 55.8% (95% CI, 43.3 to 68.4). Thirty-four patients experienced grade ≥ 3 hematologic toxicity. There were 15 cardiac events, of which seven were grade 1 to 2, five were grade 3 to 4, and three were fatal, reflecting the poor cardiac status of the study population. Conclusion Our phase II multicenter trial showed that the R-GCVP regimen is an active, reasonably well-tolerated treatment for patients with DLBCL for whom anthracycline-containing immunochemotherapy was considered unsuitable because of coexisting cardiac disease.

Abstract Background: Loss of major histocompatibility Class II antigens (MHCII) in diffuse large B-cell lymphoma (DLBCL) is associated with a decreased CD8+ tumor-infiltrating T-lymphocyte (TIL) response and poor patient survival. Transcription of the MHCII gene complex is under the control of the master transactivator, CIITA, which in part is regulated by histone acetylation. We tested the hypothesis that combination of histone deacetylase inhibitor vorinostat with standard chemotherapy will enhance MHCII expression and improve patient outcome in DLBCL. Methods: SWOG S0806 was a phase I/II open label trial of vorinostat given at 400 mg po daily on days 1-9 (subsequently reduced to days 1-5) combined with Rituximab-CHOP (R-CHOP) at standard doses, given on day 3 of a 21-day cycle for 8 cycles. Eligibility criteria included having newly diagnosed advanced stage DLBCL, international prognostic index (IPI) of at least 1, and lack of known CNS involvement or HIV. Primary endpoint of phase I was to establish maximum tolerated dose (MTD) of vorinostat with standard R-CHOP. Primary endpoint of phase II was to estimate 2-year progression free survival (PFS). Translational endpoints included correlation of pre-treatment acetylation status of histones, expression of MHCII genes, and percentage of TIL to PFS; and correlation of cytokine profile to response and outcomes. Results: Phase I was open in 5 SWOG institutions and enrolled 11 patients. There were only 2 patients who had dose limiting toxicities in the first cycle - grade 3 febrile neutropenia and grade 4 hypokalemia - allowing phase II to proceed with the original vorinostat dosing of 400 mg daily days 1-9, at all SWOG institutions. However, excess rates of febrile neutropenia and sepsis were seen upon further follow up, and the study was amended to reduce the duration of vorinostat to days 1-5. A total of 72 patients were enrolled in phase II, of which 8 were ineligible and 2 withdrew consent prior to treatment. For the remaining 62 patients, median age was 64 years, 92% had stage III/IV disease, 39% B symptoms, 61% elevated LDH, 39% had more than 1 extranodal site of involvement, with IPI breakdown of 13/26/47/13/2%. Notable grade 3-4 non-hematologic toxicities included febrile neutropenia (39%), sepsis (18%), fatigue (15%), hypokalemia (11%), hyponatremia (10%), and small bowel perforation (3%). Grade 3-4 hematologic toxicities included neutropenia (60%), anemia (35%), and thrombocytopenia (35%). There was one death in phase I from sepsis and multi-organ failure at the end of 8 cycles of treatment, but no deaths from toxicity in phase II. Overall response rate was 81% (95% CI: 69-90%). With median follow-up of 24.3 months, estimate of 2-year PFS is 72% (95% CI: 58%, 81%) and of 2-year OS is 85% (95% CI: 74%, 92%). Analysis of the panel of 30 cytokines performed on matched serum specimens of 40 patients showed correlation of baseline elevated IL-2R levels with worsened PFS and OS, and correlation of decrease in Epidermal Growth Factor level with improved PFS and OS. Results of immunohistochemical stains for expression of MHCII genes and percentage of TIL will be reported at the meeting. Conclusions: The regimen of vorinostat-R-CHOP achieved 2-year PFS estimate of 72%, which is slightly more than 68% expected from R-CHOP alone per IPI adjusted historical rate, but less than an IPI adjusted target of 78% that would be sufficient to warrant further investigation. It also resulted in unexpected excess rates of febrile neutropenia and sepsis. This regimen cannot be recommended for the broad DLBCL population. Current studies are focused on finding biomarkers of response to histone deacetylase inhibitors. Disclosures Persky: Gilead Sciences, Inc: Speakers Bureau.

Abstract Abstract 2688 Poster Board II-664 Rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) and dose-dense CHOP therapy has improved the treatment results of diffuse Large B-cell lymphoma (DLBCL) patients. Nevertheless, a substantial number of patients progress or relapse. Bortezomib is a proteasome inhibitor that is widely used in myeloma treatment and was recently approved for use in mantle cell lymphoma treatment. Its antitumor activity in DLBCL patients was reported in several studies, both as a single agent and in combination with chemotherapy. In this study, we tried to add bortezomib to dose-dense CHOP every 2 weeks to evaluate the complete response (CR) rate and safety of the treatment. Patients with previously untreated disseminated stage DLBCL and age 70 years or less were eligible. All patients received CHOP (Cyclophosphamide 750 mg/m2 IV, doxorubicin 50mg/m2 IV, vincristine 1.4mg/m2 IV on day 1, and prednisolone 100mg PO on days 1 to 5) and granulocyte colony-stimulating factor at a dose of 5μg/kg from days 4 to 13 every 2 weeks. Bortezomib, as recommended by the previous phase I trial, was administered at a dose of 1.6mg/m2 on days 1 and 4 of each cycle. Thirty-five patients were enrolled from March, 2007 to March 2009. Total 188 cycles of treatment were done. Twenty-six patients finished planned 6 cycles of treatment, while 9 patients could not continue all planned treatment due to treatment related toxicities and one patient experienced disease progression after 5 cycles of treatment. Twenty-four patients had a CR (92.4%), one patient had a partial response (3.8%), and one patient had a progressive disease (3.8%). Grade 3 hematologic toxicity episodes occurred including 20 anemia (10.7%), 4 neutropenia (2.1%), and 6 thrombocytopenia (3.2%). Grade 4 hematologic toxicity episodes comprised 2 anemia (1.6%), 11 neutropenia (5.9%), and 6 thrombocytopenia (3.2%). One patient died of severe infection with neutropenia. Among 35 patients, grade 3 non-hematologic toxicity occurred with fatigue (11.4%), nausea (2.9%), vomiting (5.7%), diarrhea (8.6%), abdominal pain (8.6%), and sensory neuropathy (20.0%). One patient experienced grade 4 constipation. This interim analysis shows that bortezomib plus dose-dense CHOP every two weeks showed promising activity in disseminated DLBCL patients as the first-line treatment with acceptable toxicity. Further accrual will be continued till the planned patient enrollment goal for phase II results. Disclosures: No relevant conflicts of interest to declare.

Purpose Obinutuzumab (GA101), a type II, glycoengineered, humanized anti-CD20 monoclonal antibody, was superior to rituximab in human diffuse large B-cell lymphoma (DLBCL) and mantle-cell lymphoma (MCL) xenograft models. In phase I of our study, obinutuzumab (GA101) exhibited encouraging activity but no clear dose-response relationship, and few patients had aggressive histologies. The efficacy and safety of two doses of obinutuzumab (GA101) were explored in our randomized phase II trial in patients with heavily pretreated DBLCL and MCL. Patients and Methods Patients were randomly assigned to receive eight cycles of obinutuzumab (GA101) either as a flat dose of 400 mg for all infusions (days 1 and 8 of cycle 1; day 1 of cycles 2 to 8) or 1,600 mg on days 1 and 8 of cycle 1 and 800 mg on day 1 of cycles 2 to 8. Results Forty patients were enrolled: 21 patients in the 400/400-mg treatment arm (DLBCL, n = 10; MCL, n = 11) and 19 patients in the 1,600/800-mg arm (DLBCL, n = 15; MCL, n = 4). End-of-treatment response was 28% (32% and 24% in the 1,600/800-mg and 400/400-mg study arms, respectively). Best overall response rates were 37% in the 1,600/800-mg arm and 24% in the 400/400-mg study arm (DLBCL, eight [32%] of 25 patients; MCL, four [27%] of 15 patients). Five (20%) of 25 rituximab-refractory patients exhibited treatment response, including four of 12 in the 1,600/800-mg group. The most common adverse events were infusion-related reactions (IRRs), which were manageable. Three patients had grade 3/4 IRRs. Grade 3/4 neutropenia was seen in only one patient. Conclusion Obinutuzumab (GA101) 1,600/800 mg achieves early steady-state concentration and clinical activity with an acceptable safety profile in relapsed/refractory DLBCL and MCL, supporting further exploration.

Abstract Background: Non-Hodgkin's lymphoma (NHL), which includes diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and mantle cell lymphoma (MCL), is associated with a high unmet need in the relapsed and refractory setting. The PI3K/AKT/mTOR pathway has been shown to play a key role in the pathogenesis of NHL. Overexpression of PIK3CD (encoding the PI3Kd isoform) is common in B-cell malignancies and is therefore widely viewed as a therapeutic target in NHL. PIK3CA and PIK3CB are also expressed in B-cell malignancies, with PIK3CA overexpression seen particularly at relapse, thereby justifying exploration of pan-PI3K inhibitors in the relapsed or refractory setting. Buparlisib (BKM120) is an oral pan-class I PI3K inhibitor which has demonstrated activity in patients with solid tumors as well as in in vitro and in vivo models of hematologic malignancies. Methods: The primary objective of this Phase II study (NCT01693614) was to evaluate the efficacy of buparlisib in three parallel cohorts of adult patients with relapsed or refractory DLBCL, FL, or MCL. Secondary objectives were to evaluate safety and tolerability, progression-free survival, duration of response, and overall survival. Inclusion criteria were: patients with relapsed or refractory disease who have received at least one prior line of therapy; at least one measurable nodal lesion (≥2 cm); ECOG performance status ≤2; and adequate bone marrow and organ function. Patients with DLBCL must have received, or be ineligible for, autologous or allogeneic stem cell transplant. All patients received single-agent buparlisib 100 mg orally QD continuously until progression, intolerance, or patient withdrawal. Tumor response was evaluated by investigators per standard criteria (Cheson, 2007). Results: At data cut-off (June 19, 2014), 64 patients had been enrolled; 26 DLBCL, 24 FL, and 14 MCL. Here, results are presented for the DLBCL cohort only. Updated results from the DLBCL cohort including biomarker analyses and results for the FL cohort will be presented at the meeting. The MCL cohort is currently enrolling. For the DLBCL cohort, median age (range) was 63.5 (28–81) years and 69% were male. The median (range) number of prior therapy regimens was 3 (1–12). Specific prior therapies included: rituximab (n=25, 96%) and bendamustine/carmustine (n=8, 31%); all patients had received prior anthracycline and an alkylating agent (e.g. cyclophosphamide), and 6 (23%) patients had undergone prior stem cell transplantation. The most common (≥15%) AEs (all grades) regardless of causality were hyperglycemia and nausea (39% each), depression (31%), anxiety and fatigue (23% each), vomiting and diarrhea (19% each), and abdominal pain (15%). Alanine transaminase or aspartate transaminase elevations were rare (4% each, with no Grade 3/4 AEs). The most common (>5%) Grade 3/4 AEs regardless of causality were hyperglycemia (23%), and nausea, depression, anxiety, urinary tract infection, and neutropenia (8% each). Six (23%) patients discontinued therapy due to AEs (potentially treatment-related). Seven on-treatment deaths were reported: 6 were disease-related and 1 was suspected to be treatment-related (unexplained death following a gastrointestinal [GI] bleed in a patient with massive GI lymphoma involvement). Overall response rate was 12% (95% CI = 2.4, 30.2) with 3 responses: 1 complete response (4%) and 2 partial responses (8%). Five patients had stable disease (19%). Eight patients (31%) experienced some decrease in tumor burden (Figure 1). At data cut-off, 2 patients demonstrated durable responses, as they were still on study treatment after 9.2 and 7.4 months, respectively. Figure 1 Figure 1. Conclusions: Early results from this Phase II study of the pan-PI3K inhibitor, buparlisib, demonstrate encouraging clinical activity, and a favorable safety profile in heavily pretreated patients with relapsed or refractory DLBCL. These data suggest that targeting all 4 PI3K isoforms in DLBCL is a viable strategy and worthy of further exploration in patients with NHL. Future combination studies with buparlisib will take a mechanism-based approach.

Abstract Backgrounds Histone deacetylases (DACs) are involved in chromatin structure regulation and function. Treatment with DACs inhibitors leads to the activation or repression of genes regulating apoptosis, proliferation, differentiation, angiogenesis, immune responses. These agents resulted to be active for the treatment of T and B-cell lymphoma and other haematological malignancies. Previous in vitro studies underlined the possible pathophysiological role of DACs in diffuse large B-cell lymphoma (DLBCL). In FIL-PanAL10 we evaluate the therapeutic activity and safety of Panobinostat, a potent pan-DACs inhibitor, in patients with relapsed or refractory (R/R) DLBCL. Methods FIL-PanAL10 (NCT01523834) is a phase II, prospective multicenter trial of the Fondazione Italiana Linfomi (FIL). Enrolled patients are ≥ 18 years old with R/R DLBCL, following ≥ 1 line of chemo-immunotherapy (R-CHOP) including high dose therapy with autologous stem cell support (ASCT) in eligible patients. Patients with > 5 prior systemic lines of treatment, CNS involvement, HIV positivity, impaired cardiac function (according to the protocol) are excluded. Patients are scheduled to receive Panobinostat po 40 mg three-times every week as part of a 4-weeks treatment cycle up to disease progression, unacceptable toxicity, or patient’s refusal. The primary endpoint of the study is to explore the antitumor activity of Panobinostat in terms of overall response (ORR) according to the Cheson criteria 1999. Secondary objectives are the evaluation of complete response (CR), time to response (TTR), progression free survival (PFS), overall survival (OS) and safety. Exploratory objectives evaluate the predictive role of pharmacogenetics, immunohistochemical and specific gene expression in relation to the response to Panobinostat; for this aim a new lymph node or other pathologic tissue biopsy is requested before starting treatment. With the null (P0) and P1 hypothesis of overall response (ORR) corresponding to <10% and ≥ 30%, 35 patients will be needed (α: 0.5; β: 0.10) and at the end of the trial treatment with Panobinostat will be considered active if ≥ 7 responses will be occurred. Results Between February 2011 and May 2013, 23 patients were enrolled on this study. Patients’ median age is 73 years (range 44-83 years); 7 (30%) patients received ≥ 3 previous lines of chemotherapy. Five patients responded to Panobinostat (ORR= 22%) including 3 CR (13%) and 2 (9%) partial response (PR): 1 patient had (4%) stable disease (SD). TTR was 2.5 months (range 2-3 months ). All 6 patients with ORR or SD are still in treatment with Panobinostat after 4, 5, 12, 12, 15, 24, months; 17 patients discontinued therapy because of progression (15) or side effects (2). After a median period of observation of 11 months from the beginning of treatment, 1-year PFS and OS are 22% and 28%, respectively. Most common observed grade 3-4 adverse events were hematological and included thrombocytopenia (88%) and neutropenia (34%); grade 3-4 diarrhoea was present in 3 (13%). The therapeutic schedule was modified from the three times week to three times every other week in 15 patients; a further dose reduction from 40 mg to 30 mg resulted to be necessary in 8 patients. The analysis of exploratory biologic objectives and of their relationship with outcome is still under investigation and will be ready for December 2013. Conclusions The preliminary results of this study indicates that Panobinostat is an active salvage therapy in nearly 20% of heavily pretreated R/R DLBCL patients; the relatively short TTR observed allows a prompt shift to other rescue treatments in non responders. The analysis of biologic biomarkers will hopefully better address Panobinostat therapy to a specific biologic subgroup.

Background/Aims: Rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) every 14 days seems to achieve better outcomes than R-CHOP every 21 days in diffuse large B-cell lymphoma (DLBCL) patients. Currently, the standard regimen is R-CHOP every 21 days. Methods: This is a phase II clinical trial of treatment with 6 cycles of R-CHOP-14 with pegfilgrastim support in 2 populations of previously untreated DLBCL patients aged ≥65 years (n = 73) or <65 years (n = 51) with low-risk International Prognostic Index scores (0-2). Results: With a median follow-up of 63.7 months, the 5-year event-free survival rate was 53.8% in patients aged ≥65 years and 71.0% in patients aged <65 years. The 5-year overall survival rate was 71.4 and 89.8%, respectively. The complete remission rate was 69.9% for older and 80.4% for younger patients. The median relative dose intensity of cytotoxic drugs was 143.2% in the elderly and 149.1% in the young patients. Febrile neutropenia was the most common grade 3-4 adverse event, being higher in elderly patients (21.3 vs. 9.3%). Eight deaths (7 in elderly patients) were considered treatment related. Conclusion: In conclusion, the R-CHOP-14 regimen is feasible and very active, though it is more toxic in elderly patients mainly due to an increased incidence of infections. New strategies, such as new monoclonal antibodies or new targeted therapies, are needed to improve the outcomes of DLBCL patients.
