17510 Background: More than 56,000 new cases of non-Hodgkin’s lymphoma (NHL) will be diagnosed this year in the United States. As our aging patient population develops worsening performance status and co-morbidities, it seems appropriate to develop effective lymphoma treatments, which have fewer toxicities and lower costs for administration. One approach is to combine non-myelosuppressive therapies. One non-myelosuppressive agent, which has efficacy in lymphoma, is gallium nitrate. Investigation of gallium nitrate for cancer treatment dates back to the 1970’s and it has been shown to inhibit ribonucleotide reductase and bind transferrin and potentially complex with transferrin and/or transferrin receptor, which is highly expressed in intermediate and aggressive histology lymphomas. It appears that the binding of the transferrin receptor on the lymphocyte as well as its inhibition of ribonucleotide reductase, eventually impairs iron metabolism, which is a necessary component of the intracellular cytochrome systems/mitochondrial function and ultimately oxidative phosphorylation. Methods: The current study is a phase II clinical trial investigating the combination of gallium nitrate, rituximab and dexamethasone (GaRD) for relapsed or refractory DLBCL, MCL or transformed follicular lymphomas. The gallium nitrate is given at 200mg/m2 CIV days 1–7, rituximab 375mg/m2 IVPB day 1 and dexamethasone 40 mg po days 1–4. Eligible patients must have proven relapsed or refractory disease and have a SWOG PS ≤3. Patients may have failed prior ASCT or allogeneic SCT. The accrual goal was 37 patients however the study was stopped after 22 patients were accrued as the primary endpoint was reached after the initial interim analysis. Results: ORR 12/22 (55%); CR/CRu 6/22(27%); PR 6/22(27%); SD 3/22 (14%); and PD 7/22 (32%). Most of these patients were refractory to prior salvage regimens 15/22 (68%), including ESHAP, DHAP or high-dose cyclophosphamide. No patients developed grade 3 or 4 toxicities, with the exception of grade 4 lymphopenia. Conclusions: Gallium nitrate, rituximab and dexamethasone (GaRD) appears to be an effective and non-toxic salvage regimen for patients with relapsed DLBCL [Table: see text]

More than 56,000 new cases of non-Hodgkin’s lymphoma (NHL) will be diagnosed this year in the United States. Despite advances in treatment modalities such as radiation, biologic agents, and cytotoxic chemotherapeutic regimens, only 25–30% of these patients will be cured of their disease. Standard salvage regimens such as DHAP, ESHAP, ICE and EPOCH have proven efficacy at the cost of increasing toxicity and hospitalization costs. The reported response rates for these are on the order of 50–75% as first-line salvage regimens. However, as our aging patient population develops worsening performance status and co-morbidities, it seems appropriate to develop effective lymphoma treatments, which have fewer toxicities and lower costs for administration. One approach is to combine non-myelosuppressive therapies. One non-myelosuppressive agent, which has efficacy in lymphoma, is gallium nitrate. Investigation of gallium nitrate for cancer treatment dates back to the 1970’s. While it is currently approved for the treatment of bisphosphonate resistant hypercalcemia of malignancy, it has also been shown to inhibit ribonucleotide reductase and bind transferrin and potentially complex with the transferrin receptor, which is highly expressed in intermediate and aggressive histology lymphomas. It appears that the binding of the transferrin receptor on the lymphocyte as well as its inhibition of ribonucleotide reductase, eventually impairs iron metabolism, which is a necessary component of the intracellular cytochrome systems/mitochondrial function and ultimately oxidative phosphorylation. The current study is a phase II clinical trial investigating the combination of gallium nitrate, rituximab and dexamethasone (GaRD) for relapsed or refractory DLBCL, MCL or transformed follicular lymphomas. The gallium nitrate is given at 200mg/m2 CIV days 1–7, rituximab 375mg/m2 IVPB day 1 and dexamethasone 40 mg po days 1–4. Eligible patients must have proven relapsed or refractory disease and have a SWOG PS <3. Patients may have failed prior ASCT or allogeneic SCT. The accrual goal is 37 patients. We have enrolled 14 patients on study to date and have 12 evaluable patients; as part of the ongoing safety evaluation for this study, we have the following results: ORR 9/12 (75%); CR 2/12 (17%); PR 7/12 (58%); SD 2/12 (17%); and PD 1/12 (8%). Most of these patients were refractory to prior salvage regimens 8/12 (67%), including ESHAP, DHAP or high-dose cyclophosphamide. No patients developed grade 3 or 4 toxicities, with the exception of grade 4 lymphopenia and grade 3 anemia (most likely due to transferrin receptor binding). Conclusions: gallium nitrate, rituximab and dexamethasone (GaRD) appears to be an effective and relatively non-toxic salvage regimen for patients with relapsed DLBCL, MCL or transformed FL.

Abstract Abstract 1759 Background The prognosis of patients with relapsed or refractory aggressive B-cell lymphoma after the conventional first line chemotherapy is still disappointing. Although several rituximab combined salvage regimens were reported, the optimal treatment has not yet been established. We therefore evaluated the efficacy and toxicity of a non-anthracycline based salvage regimen, consisting of rituximab, ifosfamide, etoposide, cytarabine and dexamethasone (R-IVAD) in patients with relapsed or refractory aggressive B-cell lymphoma. Patients and methods Patients with relapsed or refractory CD20-positive diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma grade 3 (FL G3) were consecutively enrolled in this treatment. R-IVAD consisted of rituximab (375 mg/m2 on day -2), ifosfamide (1500 mg/m2 on day 1–5), etoposide (150 mg/m2 on day 1–3), cytarabine (100 mg/m2 on day 1–3) and dexamethasone (40 mg/body on day 1–3). Treatment was given every 3 weeks up to a total of 3 courses with support of granulocyte colony stimulating factor. For responders under 65 years old with good performance status (PS), we planed peripheral stem cell collection after the third cycle of R-IVAD and consolidating high-dose chemotherapy (HDC) with cycrophosphamide (60 mg/kg on day -7,-6), etoposide (500 mg/m2 on day -6, -5, -4) and ranimustine (250 mg/m2 on day -3, -2) followed by autologous stem cell transplantation (ASCT). Results Thirty-two patients (25 DLBCL and 7 FL G3) with a median age of 64 years old (range 38–79) participated in this study and received an average of 2.6 cycles of R-IVAD. There were 21 relapsed and 11 primary refractory patients. The overall response (OR) and the complete response (CR) rate were 72% and 56% respectively. The OR rate of relapsed patients was significantly higher than that of primary refractory patients (86% vs. 45%, p=0.035). With a median 16 months (range 2–99) of follow up, the 2-year overall survival (OS) and the event-free survival (EFS) for all patients were 55% and 36% respectively. Of the 11 eligible patients, 10 successfully proceeded to HDC/ASCT with an average of 5.5 × 106/kg of harvested CD34-positive cells, resulting in the 2-year OS of 90%. No treatment related death was observed during the investigation. Multivariate analysis revealed that the age > 60 years, PS ≥ 2, extranodal sites ≥ 2, and primary refractory disease were independently associated with worse survival. Conclusion R-IVAD regimen, which efficiently mobilizes peripheral stem cells, is a safe and efficacious alternative for patients with relapsed or refractory aggressive B-cell lymphoma. Disclosures: No relevant conflicts of interest to declare.

e19551 Background: The AE rates and HRU reported in multiple real-world evidence (RWE) studies of chimeric antigen receptor T-cell (CAR-T) therapies tisa-cel and axi-cel in r/r DLBCL have differed from those in their clinical trials. However, the cost implications from these findings are not well understood in existing literature. This study summarizes information from these RWE studies of tisa-cel and axi-cel and quantifies the associated costs. Methods: A literature review was conducted to identify RWE studies reporting AE rates and HRU of tisa-cel and axi-cel in the United States (US). AE rates and HRU were summarized and the associated costs were estimated using a micro-costing approach. Costs of AE management included hospitalization and pharmacy costs, such as intensive care unit (ICU) stays, inpatient admissions, and medications for the treatment of cytokine release syndrome (CRS) and neurotoxicity events (NE). HRU costs included hospitalization, ICU stays, and outpatient visit costs. Unit costs were from public health databases that are representative of US healthcare system and from literature. Costs were inflated to 2020 US dollars. A range was reported to present evidence if inputs are available from multiple studies. Results were summarized for tisa-cel and axi-cel separately. Results: Four publications were identified: Jaglowski 2019, Pasquini 2019, Riedell 2019, and Jacobson 2020. Across studies, grade 3+ CRS and NE occurred in 1%-4% and 0%-5% of tisa-cel-treated patients and 7%-16% and 20%-35% of axi-cel-treated patients, respectively. Tocilizumab usage was reported in 14%-20% of tisa-cel- and 62%-71% of axi-cel-treated patients. CAR-T infusion was inpatient for 36% of tisa-cel- and 92%-100% of axi-cel-treated patients. The median hospitalization days was 2 for tisa-cel and 15-16 for axi-cel. ICU transfer was observed for 7% and 28%-38% of tisa-cel- and axi-cel-treated patients, respectively, with median stays of 4 and 5 days, respectively. The median number of outpatient visits within 28 days after infusion was 6 for tisa-cel and 4 for axi-cel. The total estimated costs for managing AEs per patient were $843-$1,962 for tisa-cel and $5,979-$10,878 for axi-cel. The total estimated HRU costs per patient were $3,321 for tisa-cel and $32,394-33,166 for axi-cel. Conclusions: RWE studies suggest that patients with r/r DLBCL receiving tisa-cel had numerically lower AE rates, HRU, and cost burden than those receiving axi-cel in the US. The additional cost burden for axi-cel was primarily driven by the incremental ICU and hospitalization care due to a higher proportion of inpatient infusion among patients receiving axi-cel. Further research is warranted to compare the costs associated with the two CAR-Ts in r/r DLBCL.

8505 Background: Although level 1 evidence is lacking, the majority of patients (pts) with LSCLC are treated with a high dose QD TRT regimen in clinical practice. CALGB 30610/RTOG 0538 was designed to determine if administering high dose TRT would improve overall survival (OS), compared with standard 45 Gy BID TRT, in LSCLC pts treated with chemoradiotherapy. Methods: Eligible pts had LSCLC, ECOG performance status (PS) 0-2 and regional lymph node involvement excluding contralateral hilar or supraclavicular nodes. This phase 3 trial was conducted in 2 stages. In the first stage, pts were randomized 1:1:1 to 45 Gy BID over 3 weeks, 70 Gy QD over 7 weeks, or 61.2 Gy concomitant boost (CB) over 5 weeks. For the second stage, the study planned discontinuation of one high dose arm based on interim toxicity analysis with patients then randomized 1:1 in the two remaining arms. TRT was given starting with either the 1st or 2nd (of 4 total) chemotherapy cycles. The primary endpoint was OS measured from date of randomization. Results: The trial opened 03/15/2008 and closed 12/01/2019 upon completing accrual, with the CB arm discontinued 3/11/2013 after interim analysis. This analysis includes 638 pts randomized to 45 Gy BID TRT (n = 313) or 70 Gy QD TRT (n = 325). Median age was 63 years (range 37-81), the majority of pts were Caucasian (86%), female (52%), and with ECOG PS 0-1 (95%). After median follow-up of 2.84 years (IQR:1.35 -5.61) for surviving pts, QD compared to BID did not result in a significant difference in OS (HR 0.94, 95% CI: 0.76-1.2, p = 0.9). Median, 2- and 4-year OS for QD were 30.5 months (95% CI: 24.4-39.6), 56% (95% CI: 0.51-0.62), and 39% (95% CI: 0.33-0.45), and for BID 28.7 months (95% CI: 26.2-35.5), 59% (95% CI: 0.53-0.65), and 35% (95% CI: 0.29-0.42). QD also did not result in a significant difference in PFS (HR 0.96, 95% CI: 0.78-1.18, p = 0.94). Most grade 3+ hematologic and non-hematologic adverse events (AEs) were similar between cohorts. Rates of grade 3+ febrile neutropenia, dyspnea, esophageal pain and dysphagia for QD were 12.6%,7%, 11.6% and 11.3%, and for BID 13.6%, 4%, 11.2 % and 9.5%. Grade 5 AEs were reported in 3.7% and 1.7% of the QD and BID cohorts, respectively. Results will be updated at presentation. Conclusions: High dose QD TRT to 70 Gy did not significantly improve OS compared with standard 45 Gy BID TRT. Nevertheless, favorable outcomes on the QD arm provide the most robust evidence available supporting high dose once-daily TRT as an acceptable option in LSCLC. Outcomes from this study, the largest conducted in LSCLC to date, will help guide TRT decisions for this patient population.

Abstract Background. Combined immunochemotherapy with CHOP and rituximab have improved the outcome of patients with diffuse large B-cell lymphoma (DLBCL). and related diseases. However, the cure rate of patients with IPI 3–5 or aaIPI 3 is still only about 50% with this regimen. Given the feasibility of previous CLSG regimens based on high-dose CHOP-ESHAP induction and BEAM consolidation, we have conducted a phase II trial combining this approach with rituximab immunotherapy. Patients and methods. Patients aged 18–65 years with DLBCL and age-adjusted IPI (aaIPI) 2–3 were treated with three cycles of high-dose CHOP (MegaCHOP - cyclophosphamide, 3 g/m2, vincristine 2 mg, adriamycin, 75 mg/m2, and prednisone, 300 mg/m2) with G-CSF every 3 weeks, followed by three cycles of ESHAP (etoposide, 240 mg/m2, cisplatin, 100 mg/m2, methylprednisolone, 2000 mg and Ara-C 2000 mg/m2) every 3 weeks. Four to six doses of rituximab 375 mg/m2 were administered on day 1 of each cycle of induction therapy. High-dose therapy (BEAM) followed by autologous stem cell transplant (ASCT) was used as consolidation. Radiotherapy was given to residual masses or sites of bulky disease. Primary endpoint was progression-free survival (PFS), while secondary endpoints were overall survival (OS) and feasibility of the treatment. Results. From April 2002 to October 2006, 105 consecutive patients from 10 centers were recruited. 58% were men and 42% women with median age 46 years (19–63 years). 74% of patients had stage IV disease, 92% had elevated LDH, 53% had performance status &gt;1, 55% had B symptoms and 19% had bone marrow involvement. aaIPI was 2 in 62% of patients and 3 in 38% of patients. 68% of patients received the whole treatment according to the protocol, including ASCT and radiotherapy. Stem cells mobilization according to the protocol was performed in 90% of patients and was successful in 86% of mobilized patients (77% of all patients). 73% of patients ultimately received ASCT (including 3 patients transplanted after ammended treatment) and 51% of patients received planned radiotherapy. Complete remission (CR) was achieved in 83% of all patients and partial remission (PR) in 2%. Early toxic death rate was 6% and 9% patients had primary refractory disease. Of patients who achieved CR or PR, only 6 subsequently relapsed (7%) and two suffered late toxic death (2%). With a median follow-up of 32 months for living patients, the estimated 2-year PFS is 77% and 2-year OS is 81%. Age less than median (46 years) was strongest predictor of favorable outcome (p = 0,00006 for PFS and p = 0,00013 for OS), while there was no effect of stage, LDH, performance status or aaIPI (2-year PFS 79% for aaIPI 2 and 77% for aaIPI 3, 2-year OS 81% for aaIPI 2 and 80% for aaIPI 3). Delivery of ASCT or radiotherapy did not significantly affected PFS in patients who did not suffered early progression or early toxic death, but radiotherapy modestly improved OS of these patients (p = 0,03). Conclusion. R-MEB has proved to be an effective treatment strategy for younger patients with high-risk aggressive B-cell lymphoma. Currently, CLSG is testing whether utilization of early PET scan may decrease toxicity and improve treatment tolerance while maintaining the efficacy of this regimen.

Abstract Abstract 2805 CHOP – based chemotherapy for aggressive lymphomas in patients with age-adjusted International Prognostic Index (IPI) score of 2–3 resulted in a historical 3-year progression free survival of approximately 30% in a previous Nordic phase III study. The aim of the present study is to determine whether an intensified regimen with chemoimmunotherapy and CNS prophylaxis improves outcome. Methods: From October 2004 to June 2008 patients were included in a phase II study. Inclusion criteria: 1) Age 18–65 years. 2) Newly diagnosed de novo diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) grade III. 3) No clinical sign of CNS disease and negative CSF cytology/flow cytometry by lumbar puncture. 4) No HIV infection. 5) WHO performance score 0–3. 6) Adequate organ functions. Schedule: Six courses of R-CHOEP14. Pegfilgrastim 6 mg sc. day four of each cycle. One course of high dose cytarabine 12 g/m2 (6 g/m2 for patients 60–65 years). One course of high dose methtrexate 3 g/m2 (1 g/m2 for patients 60–65 years). Biopsy and/or 18FDG PET/CT imaging of residual masses after fulfilled therapy was recommended, but not mandatory. Radiotherapy was given to residual masses of uncertain significance. Results. Demographic data:.156 eligible patients were included (97 males). Median age: 54 years (range 20–64). Histology: DLBCL: 145, FL grade 3: 12 (three patients no data). Age adjusted IPI score: 2: 117; 3: 39. Stage III-IV: 150 patients. LDH elevated: 151 patients. Performance status 2–3: 51 patients. B-symptoms were registered in 97 patients, more than one extranodal site in 42 and bulky lesions (≥ 10 cm) in 68. Median observation time for patients alive at last follow up was 36 months. Toxicity: Three toxic deaths are registered, one large bowel perforation, one fulminant hepatic necrosis and one septic shock. Hematological toxicity grade 4 was seen in 78% of the patients, infection grade 4 in 8%. Radiotherapy was given to 16% of the patients. Response: Response rates at end of therapy: CR/CRu: 69%, PR: 22%, SD: 1%, PD: 4.5%. Seventeen patients (7%) were not treated according to protocol, either due to lack of response (6 patients) or due to toxicity (eleven patients). The majority of the PR patients were considered to have residual masses and not viable tumour tissue. Survival: Three year overall survival was 80% (95% CI +/− 6.5%) and three year treatment failure free time 67% (95% CI +/−8.0%). CNS events: Seven patients had a CNS relapse, all but one were isolated (4 intracerebral, 3 meningeal). All CNS relapses occurred within 6 months after inclusion. Conclusions: The results are promising with a low three year treatment failure rate, a low toxic death rate and fewer CNS events than expected. The CNS events might be further reduced by earlier CNS prophylaxis.

e19005 Background: No standard salvage regimen exists for patients (pts) with relapsed or refractory (RR) NHL or CLL. Bendamustine, pentostatin and ofatumumab have activity in pts with CLL and NHL, but have not been combined as a single regimen. We conducted a phase I trial to assess the safety of this regimen. Methods: Pts with RR B-NHL or CLL were eligible. The design was a standard 3+3 using escalating doses of Bendamustine (50, 70, or 90 mg/m2 D1-2), Pentostatin (4 mg/m2 D1), and Ofatumumab (cycle 1: 300 mg D1; cycle 2-6: 1000 mg D2) every 28 days. Responses were assessed after cycle 3. Results: Ten pts were enrolled (6M/4F). Median age was 56 (range 37-65). Pts had follicular (FL) NHL (n = 2), CLL or SLL (n = 6), primary mediastinal B-cell lymphoma (PMBL) (n = 1), and extra-nodal marginal zone (MZL) NHL (n = 1). Pts had relapsed (n = 7) or refractory disease (n = 3) and received a median of 3 prior lines of therapy (range 1-4). Two CLL pts had high risk cytogenetics: 11p (n = 1) and 17p (n = 1). Most NHL pts (3/4) had stage 4 disease and all were refractory to rituximab. The ORR was 90% (PR = 5 pts: FL = 2, CLL/SLL = 3; CR = 4; CLL = 3, MZL = 1). One pt with PMBL progressed on treatment and died. One pt with CLL relapsed after 6 months. After a median follow up of 17 mo, the OS was 90% and PFS was 80%. Two pts (FL and CLL/SLL) subsequently underwent allogeneic stem cell transplant. DLT was not reached. Grade 3-4 toxicities included electrolyte imbalance (50%), neutropenia (30%), thrombocytopenia (30%), tumor lysis (20%), neutropenic fever (20%), and infusion reactions (10%). Common grade 1-2 toxicities were hyperglycemia (90%), thrombocytopenia (80%), nausea (80%), edema (80%), fatigue (80%) and neutropenia (70%). Conclusions: The BOP regimen is well tolerated and safe in pts with RR B-NHL or CLL. No DLT toxicity was reached at the highest bendamustine dose of 90mg/m2. Targeted therapies have largely supplanted the role of chemo-immunotherapy in the salvage setting. This trial was initiated in the pre-ibrutinib era and accrual to the planned phase II portion is on hold as pts now receive targeted therapy as salvage therapy. BOP might be an option for pts refractory to other strategies. Clinical trial information: NCT01352312.

Abstract Introduction: standard treatment for relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) is high-dose chemotherapy followed by autologous stem-cell transplantation (ASCT) but this strategy is not appropriate for elderly DLBCL patients (pts) related to a high risk of toxicities. Multiple chemotherapy regimens had been developed for heavily pretreated elderly DLBCL patients such as R-bendamustine, R-gemcitabine-oxaliplatin (R-GEMOX) and pixantrone; the median progression free survival (PFS) of these regimens were 2, 4 and 3.5 months, respectively in prospective phase II studies for patients previously treated with R (Sehn 2017, Mounier 2013, Pettengel 2016). Adapted dose of ifosfamide and etoposide was firstly developed as sequential consolidation regimen after high-dose CHOP (ACVBP regimen) in first line therapy of young DLBCL patients (Tilly 2003). This regimen with a safe toxicity profile was then used in combination with R in Lyon University Hospital in elderly R/R DLBCL ineligible to intensive strategy. Methods: we retrospectively reviewed the efficacy and the safety profile of this regimen performed in two Lyon University Hospitals (Centre Hospitalier Lyon Sud and Leon Berard Cancer Center). Between June 2004 and March 2017, 75 pts with R/R DLBCL (63 de novo DLBCL, 12 transformed DLBCL) received R (375 mg/m2) in combination etoposide (300 mg/m2) and ifosfamide (1500 mg/m2) on day 1 (N=72, 96%) and on days 1-2 (N=3, 4%) at 2 (N=46, 61%) or 3-week (N=29, 39%) intervals. All medical records were reviewed for clinical and biological characteristics, modality of treatment and supportive care, toxicities, responses and outcome. Results: the median age was 79 years (range, 64-92) at the beginning of R-ifosfamide/VP16 treatment with 46% of the patients over 80 years. 13% of pts had a CIRS-G grade 3 or 4 >2 categories and 35% had a cumulative CIRS-G score more than 6. The performance status according to EORTC scale was 2-4 in 37% of the pts and 93% had III-IV Ann Arbor stages. Age-adjusted IPI were 0-1 in 20 pts (27%) and 2-3 in 55 pts (73%). All patients were previously treated in first-line therapy by R in combination with chemotherapy (CHOP, N=56, 75%, low-dose CHOP, N=14, 19%, other, N=5, 6%). The patients received a median number of 1 previous line (range, 1-8) and no patient was previously treated by ASCT. The median time between initial diagnosis and R-ifosfamide/VP16 was 20 months (range 4-187). The median time between the last treatment and R-ifosfamide/VP16 was 5 months (range 0-181). A refractory disease to first-line treatment was showed in 14 pts (19%). 31% of the patients had a refractory disease to the last regimen performed before R-ifosfamide/VP16. Patients received a median of 6 cycles (1-12). At the end of treatment, the overall response rate (ORR), defined by the rate of complete response (CR) and partial response (PR) was 37%, with 18% of CR. Evaluations were assessed for 29% of the pts by TEP scanner. For toxicity, among the 387 cycles, 10 patients developed febrile neutropenia (2.6%); 15 (20%) a grade 3-4 neutropenia; 7 (9%) a grade 3-4 thrombocytopenia; 5 patients needed platelet units and 16 patients received packed red blood cell units. No grade 3-4 non-hematological toxicity was observed and no toxic death occurred. With a median follow up of 31.3 months (range, 5.0-202.8), the median progression-free survival (PFS) was 4.3 months with a 1-year PFS rate of 26.0% (95%CI, 17.7-38.3) (Figure 1A). The median overall survival (OS) was 8.2 months with a 1-year OS rate of 40.8% (95%CI, 30.9-54.0) (Figure 1B). The median duration of response was 4 months (range 1-97). The median PFS was adversely affected by response (refractory versus CR/PR) to the last treatment (3.0 months versus 5.5 months, P=0.001) (Figure 1C). Conclusions: in this retrospective study, R-Ifosfamide/VP16 regimen provided effective results in R/R DLBCL transplant-ineligible pts with 37% of ORR and a median of PFS of 4.3 months with a safe toxicity profile. This regimen could also be considered as a platform for combinations with novel targeted agents in these categories of patients.

Abstract Background: Prognosis of diffuse large B-cell lymphoma (DLBCL) and other aggressive lymphoma entities has improved with the advent of Rituximab, and R-CHOP-21 and variants is SOC. Nevertheless, a substantial proportion of patients fail first line treatment. Salvage therapies are often effective. However, no more than 25-50% achieve a long term remission even when consolidative high dose chemotherapy (HDT) followed by hematopoietic stem cell transplantation (SCT) is applied. In case of failure or intolerance to HDT, regimen like Gemcitabine/Oxaliplatin are applied but show limited efficacy, indicating the need for new treatments. Obinutuzumab (GA101) is a type II anti-CD20 antibody. Superiority of Obinutuzumab could be demonstrated in xenograft models of mantle cell lymphoma and DLBCL. Although desirable, cumulative dose-related, progressive cardiotoxicity eliminates anthracyclins from higher treatment lines. With Pixantrone, a drug structurally related to anthracyclines and especially anthracenediones, a re-exposition against this drug class has been shown to be feasible. In 70 heavily pre-treated patients, a best ORR of 40% (20% CR/CRu) was observed (Pettengell et al). Experiences from further antibody drug combinations lead to the assumption that the effects of Pixantrone will be augmented by a monoclonal antibody without increasing toxicity. We thus initiated a trial combining both agents for the first time. The trial has opened in Q4/2015 and recruitment is ongoing. Overall, a total of up 70 patients will be enrolled for a number of 64 evaluable patients. Primary endpoint will be the objective overall response rate, with secondary endpoints being safety, PFS and OS. Methods: this is a multicenter, national, prospective trial. Inclusion criteria: patients were eligible if they had histologically proven DLBCL, FL grade IIIb or transformed indolent lymphoma, CD20 positive disease, no curative option available, relapsed disease, measurable disease, ECOG < 3, sufficient bone marrow reserve, no severe concomitant diseases and given informed consent. There was no upper limit or prior treatment lines. Treatment consisted of Pixantrone 50mg/m² day 1, 8 and 15 of each cycle, Obinutuzumab 1000 mg flat dose day 1, 8 and 15 of cycle one and day 1 of each subsequent cycle. A total of 6 cycles was planned with interim staging after 3 cycles. Results: 24 patients (pts) have been included until now. Concerning clinical characteristics, all were caucasian, 12 were female and the other 12 male and median age was 75 years. Most of the patients suffered from DLBCL (18 pts, 82%). Median number of prior therapies was 2 (1 to 6). Until now 55 evaluable cycles of chemotherapy (median 2 cycles (0 to 6)) have been performed. At this time, the treatment seems to be well tolerated, with no unforeseen side effects. Observed toxicity was predominantly hematologic. The following hematologic adverse events of grade 3/4 were noted: leukopenia (4 pts, 17%), neutropenia (6 pts, 25%), granulocytopenia (1 pts, 4%), as well as thrombocytopenia (2 pts). Non-hematologic grade 3/4 adverse events were observed in at least two patients: hypertension (2 pts) and pelvic pain (2 pts). Response: currently, best responses were 4 PR, 1 SD, and 8 PD in 13 patients evaluable so far. Four patients died, all after progression of lymphoma. Summary: the combination of Obinutuzumab and Pixantrone seems to be feasible and safe with early signs of efficacy. Updated results of this trial in progress with a focus on safety will be presented.

e15599 Background: The role of the second line chemotherapy in advanced gastric cancer was not clear, but possibility of prolongation of survival is open question. Irinotecan is promising agents in gastric cancer and this phase II study evaluated the efficacy and safety of combination chemotherapy with irinotecan, high dose of 5-fluorouracil (5-FU) and leucovorin in taxane and cisplatin based chemotherapy refractory metastatic gastric cancer. Methods: Eligible criteria were as followed; histologic confirmed adenocarcinoma of stomach, previously treated with taxane and cisplatin, age≥18, Eastern Clinical Oncology Group (ECOG) performance status of 1 or less, adequate organ function. Irinotecan (150 mg/m2) as a 30-min infusion and leucovorin (200 mg/m2) as a 15-min infusion were given on day 1, followed by 5-FU 400 mg/m2bolus infusion then 5-FU 2,400 mg/m2 as a 48-hour continuous infusion. This cycle was repeated every 2 weeks until disease progression or unacceptable toxicities. Results: Thirty-four patients were enrolled. The median age was 57 years (range 27–73 years), and the ECOG performance status of all patients was 1. All patients were evaluable for safety and survival and twenty seven patients (79.4%) were evaluable for tumor response. The overall response rate was 18.5% (95% CI: 3.9–33.1). The median progression free survival and overall survival were 4.6 (95% CI: 2.4–6.9) and 9.3 months (95% CI: 5.2–13.4), respectively. Greater than grade 3 haematological toxicities were neutropenia in nine (26.5%), febrile neutropenia in one (2.9%) and thrombocytopenia in one patient (2.9%). The major non-haematological toxicity was asthenia, but most of patients showed grade 1 or 2. Greater than grade 3 non- haematological toxicities were elevated AST/ALT in four (11.8%), hyperbilirubinemia in two (5.9%), nausea in two patients (5.9%). Conclusions: This results showed that the combination chemotherapy with irinotecan, 5-FU and leucovorin was well tolerated and active in taxane and cisplatin refractory patients.
