Abstract Background: Rituximab (R) plus CHOP (R-CHOP) is standard-of-care treatment for previously untreated diffuse large B-cell lymphoma (DLBCL). Approximately 35-40% of patients (pts) will relapse following R-CHOP, and outcomes with salvage therapy remain poor. Obinutuzumab (GA101; GAZYVA/GAZYVARO; G) is a glycoengineered, type II anti-CD20 monoclonal antibody with greater direct cell death induction and antibody-dependent cellular cytotoxicity/phagocytosis activity than R. In the Phase 2 GATHER study (NCT01414855), G plus CHOP (G-CHOP) demonstrated manageable toxicity and promising efficacy in pts with advanced untreated DLBCL. GOYA (NCT01287741) is an open-label, multicenter, randomized Phase 3 study comparing the efficacy and safety of G-CHOP with R-CHOP in pts with previously untreated DLBCL. GOYA was sponsored by Roche with scientific support from the Fondazione Italiana Linfomi. Methods: Eligible pts were aged ≥18 years and had adequate hematologic function, ≥1 bi-dimensionally measurable lesion, an ECOG performance status (PS) of ≤2 and an International Prognostic Index (IPI) score of ≥2 (high, high-intermediate or low-intermediate risk). Low-risk pts with an IPI score of 1 (but not due to age alone) or with an IPI score of 0 with bulky disease (one lesion ≥7.5cm) were also eligible. Pts were randomized 1:1 to receive 8 (21-day) cycles of G (1000mg i.v. on Days [D] 1, 8, and 15, Cycle [C] 1 and D1, C2-8) or R (375mg/m2 i.v. on D1, C1-8) in combination with 6 or 8 cycles of CHOP (number of cycles preplanned in advance for all pts at each site). Preplanned radiotherapy was allowed for bulky or extranodal disease. The primary endpoint was investigator (INV)-assessed progression-free survival (PFS); for the target hazard ratio (HR) of 0.75, the 3-year PFS was expected to improve from 60% to 68%. Secondary endpoints included: PFS assessed by Independent Review Committee (IRC); overall survival (OS); complete response (CR) and overall response rate (ORR) with or without PET (assessed by INV or IRC according to modified Cheson 2007 criteria); and safety. Results: 1418 pts were randomized to study treatment: 706 to G-CHOP and 712 to R-CHOP. Baseline characteristics were well balanced between the G-CHOP and R-CHOP arms: mean age, 62.0 years in both arms; ECOG PS ≥2, 12% vs. 14%; IPI score ≥3, 47% vs. 43%; Ann Arbor stage III-IV, 76% in both arms. Cell-of-origin distribution, as assessed by gene-expression profiling (NanoString), was similar in both treatment groups (GCB: 58% [271/471] G-CHOP, 58% [269/462] R-CHOP; ABC: 27% [125/471] G-CHOP, 26% [118/462] R-CHOP; Unclassified: 15.9% [75/471] G-CHOP, 16.2% [75/462] R-CHOP). For the primary endpoint of INV-assessed PFS, there was no significant difference between G-CHOP and R-CHOP (3-year PFS, 69% vs. 66%; stratified HR, 0.92; 95% confidence interval [CI], 0.76, 1.12; p=0.3868; Table). Secondary endpoints, including PFS by IRC, OS, and end-of-treatment ORR/CR rate (with and without PET), were consistent with the primary endpoint, with no clinically meaningful differences observed between the treatment arms (Table). In a prespecified subgroup analysis of INV-assessed PFS, a stratified HR of 0.72 (95% CI, 0.50, 1.01) in favor of G-CHOP over R-CHOP was determined for pts with GCB DLBCL (3-year PFS, 79% vs. 70%). No new safety signals were identified. Grade ≥3 adverse events (AEs; 74% vs. 65%) and serious AEs (43% vs. 38%) were more common in the G-CHOP than in the R-CHOP arm. Grade ≥3 AEs of particular interest that were numerically more common with G-CHOP than R-CHOP included neutropenia (57% vs. 48%), infusion-related reactions (45% vs. 32%), infections (54% vs. 44%), and thrombocytopenia (8% vs. 3%). AEs resulting in withdrawal from treatment (12% [84/704] G-CHOP; 9% [60/703] R-CHOP) and AEs with fatal outcome (6% [41/704] G-CHOP; 4% [30/703] R-CHOP) were slightly more common with G-CHOP. The most common AEs leading to death were pneumonia (5 G-CHOP; 6 R-CHOP) and sepsis/septic shock (7 G-CHOP; 3 R-CHOP). Conclusions: The primary endpoint of this study was not met: G-CHOP did not significantly improve INV-assessed PFS compared with R-CHOP in previously untreated pts with DLBCL. No unexpected safety signals were identified. Further investigation of outcomes in subgroups is planned.

Background: The combination of carfilzomib with immunomodulatory drugs (IMiDs) and dexamethasone is active in multiple myeloma (MM). Carfilzomib, thalidomide, and dexamethasone (KTd) has been studied in upfront MM treatment but has not been studied in the setting of relapsed/refractory myeloma (RRMM). The ALLG MM018/ AMN002 is an open-label phase II study of KTd in patients with RRMM. This study was conducted across 16 sites across Australia, New-Zealand, Singapore, South Korea and Taiwan. Method: Patients with RRMM with 1-3 prior lines of treatment were given carfilzomib [K: 20mg/m2 IV cycle 1 days 1 and 2, 56mg/m2 (36mg/m2 for patients age ≥75 years) from cycle 1 day 8 onwards], thalidomide (T: 100mg po nocte) and dexamethasone [dex: 40mg (20mg for patients age ≥75 years) po weekly], in a 28-day cycle. After 12 cycles, T was omitted, and K was given on days 1,2,15,16 and dex days 1,15 every 28-day cycles for a further six cycles. The primary endpoint was PFS. Secondary endpoints were ORR, overall survival, adverse events, and quality of life (QoL). The study had an 80% power to detect a ≥70% PFS at 6.5 months compared to historical ≤50% PFS at 6.5 months expected with Td (Kropff, M. et al. Haematologica 2012), at a significance level of 0.05. Results: This study has completed accrual. Eighty-three patients [median age of 66 years (42-85)] were enrolled with a median follow up of 15.9 (0.9-26) months. ORR rates were 86.4% (≥VGPR 70.2%). Median PFS was 20m (95% CI 15.9-26m). PFS at 6.5 months was 76.2% (95% CI 73.6-84.9%). Median OS has not been reached, and was 75% at 20 months. The most common grade ≥3/4 AEs were peripheral neuropathy (16%), upper respiratory tract infections (12%), dyspnoea (14%), and hypertension (10%). Grade ≥3/4 cardiac AEs occurred in 6%. The median carfilzomib dose that was delivered was 70.7% (32.8-92.6%) of the target dose. Thus far, 41% of patients have completed the intended 18 cycles of treatment. 21% of patients ceased therapy early. The most common reason for early treatment cessation was disease progression (30%) and adverse events (15%). Fifteen patients (18%) have died, 11 were due to MM, two from infection, one from an ischaemic cardiac event, and one from a traffic accident. QoL, as measured by the EQ-5D-5L instrument, remained stable throughout treatment. Conclusion: The ALLG MM018/AMN 002 study has met its primary endpoint. The KTd schedule as outlined in this study is efficacious in patients with RRMM, resulting in a prolonged PFS and a safety profile in line with previous reports for each of carfilzomib and thalidomide. KTd is an active option in jurisdictions where the cost of other IMiDs prohibits regulatory funding. Comparisons of efficacy and adverse events between the Caucasian and Asian populations will be presented at the meeting.

Abstract Background SAR3419 is a humanized anti-CD19 antibody conjugated to maytansin DM4, a potent cytotoxic agent. SAR3419 targets CD19, an antigen expressed in the majority of B cell non-Hodgkin lymphomas (NHL). The recommended dose for single agent SAR3419 was previously determined to be 55 mg/m2 administered IV every week for 4 weeks, then bi-weekly. In phase I, clinical activity was shown mainly in patients with follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL). (Trial funded by Sanofi). Methods Patients (pts) with a CD20+ and CD19+ DLBCL relapsing or refractory (R/R) after at least 1 standard treatment including rituximab and not candidate for or who already underwent transplantation, were eligible. Refractory disease was defined as unresponsive to or progressing within 6 months of regimen completion. Fresh (or recent formalin-fixed, paraffin-embedded) biopsy was required before SAR3419 start. Pts received 375 mg/m2 of rituximab (R) IV and 55 mg/m² of SAR3419 on day 1, 8, 15, 22 (35-day cycle 1), followed by bi-weekly R and SAR3419 at the same doses for 2 additional 28-day cycles, provided there was no disease progression or other study discontinuation criteria met. The primary objective was the overall response rate (ORR) following Cheson 2007 criteria, with the first tumor assessment being done 42 days after the last study treatment administration. Secondary objectives were: safety, pharmacokinetics (PK), duration of response (DOR), progression free survival (PFS), overall survival (OS) and correlation of the antitumor and biological activity of the combination with tumor biomarker status. Results Fifty-three pts were enrolled, 52 treated. Median age was 66.5 years (range 38-85), 50% were male; 23%, 33% and 40% of patients had received 1, 2 or ≥3 prior chemo/immunotherapy regimens for DLBCL, respectively. Of the enrolled patients, 3.8% had received no prior regimen for DLBCL and therefore were excluded from primary analysis for efficacy. Seventy-three percent had stage III/IV disease, 59% had elevated lactate dehydrogenase (LDH), and 63% had bulky disease. Sixty percent were refractory to first regimen (primary refractory), 16% were refractory to last regimen and 24% were relapsed pts. The ORR in the per-protocol population (n=45) was 31.1% (80% confidence interval (CI): 22.0% to 41.6%). Among the 14 responders, 5 had progressed at the time of analysis, with duration of response beyond 6 months for 3 of them. The ORR was 58.3% (80% CI: 36.2% to 78.1%) for patients with relapsed DLBCL (n=12), 42.9% (80% CI: 17.0% to 72.1%) for pts refractory to last regimen (n=7) and 15.4% (80% CI: 6.9% to 28.4%) for primary refractory pts (n=26). Overall survival and PFS data are not yet mature. Biomarkers and PK data will be presented at the meeting. The most common (≥10%) all grades non-hematologic treatment-emergent adverse events (TEAEs) were asthenia (25.0%), nausea (21.2%), cough (19.2%), diarrhea (17.3%), weight decrease (17.3%), vomiting (15.4%), dyspnea (15.4%), abdominal pain (13.5%), back pain (13.5%), pyrexia (13.5%) and constipation (11.5%). Related grade 3-4 TEAEs were: 1 syncope, 1 bronchospasm, 2 neutropenia and 1 anemia. No TEAEs led to treatment discontinuation, no grade 3-4 peripheral neuropathy or grade 3-4 ocular events were observed. Two pts experienced grade 2 keratitis, both rapidly recovered with local treatment. Hematological toxicity was moderate, with grade 3-4 neutropenia and thrombocytopenia in 15.7% and 9.8% pts, respectively. No complications related to neutropenia were reported. Grade 3 transaminase increase was observed in 1 patient. Conclusions The combination of SAR3419 plus R showed moderate ORR in R/R DLBCL; however the study population was of poor prognosis (60% refractory to first line therapy). In the relapsed DLBCL patients a higher ORR was observed. SAR3419 plus R presented with a favorable safety profile. Further investigations on biomarker expression are ongoing to identify a sub-group of pts who could have better benefited from this combination.

Abstract Introduction: Panobinostat (PAN) is a potent pan-deacetylase inhibitor that targets multiple myeloma (MM) cells via its epigenetic effects as well as its effect on the aggresome. In the PANORAMA 1 phase 3 trial, the combination of PAN, bortezomib (BTZ), and dexamethasone (Dex; PAN+BTZ+Dex) significantly increased progression-free survival compared with placebo plus BTZ and Dex, leading to approval in Europe of the combination for the treatment of patients with MM who have received ≥ 2 prior regimens, including BTZ and an immunomodulatory agent. The purpose of this expanded treatment protocol (ETP) is to further evaluate safety and to provide panobinostat prior to commercial availability to patients with relapsed/refractory MM who have received ≥ 2 prior lines of therapy but for whom satisfactory treatment alternatives are not available. Methods: Panobinostat-ETP is a multicenter, open-label, ETP study of PAN+BTZ+Dex in adult patients with MM relapsed and/or refractory to ≥ 2 prior lines of therapy. During treatment phase (TP) 1 of the study, patients received oral PAN 20 mg (days 1, 3, 5, 8, 10, and 12) plus intravenous or subcutaneous BTZ 1.3 mg/m2 (days 1, 4, 8, and 11) for eight 21-day cycles. Patients with ≥ stable disease proceeded to TP2, with maintained PAN and less frequent BTZ dosing (days 1 and 8) for an additional 8 cycles. In both phases, oral Dex 20 mg was administered on the days of and after BTZ treatment. Reduction to once-weekly BTZ was allowed prior to TP2 as a dose reduction strategy. Results: A total of 49 patients with a median age of 67 years (range, 45-85 years) were enrolled in the study. Patients were heavily pretreated; 73.5% received ≥ 3 prior lines of therapy. Most patients (n = 43 [87.8%]) received subcutaneous BTZ, while 3 (6.1%) received intravenous BTZ, and another 3 (6.1%) received both. The median duration of treatment with PAN+BTZ+Dex was 67 days (range, 12-305 days). The most common grade 3/4 hematologic laboratory abnormalities were thrombocytopenia (51.0%), anemia (12.2%), and neutropenia (10.2%). The most common nonhematologic grade 3/4 treatment-emergent adverse events (AEs) were diarrhea (14.3%), fatigue (8.2%), infection (6.1%), and nausea (6.1%). Common gastrointestinal treatment-emergent AEs of any grade included diarrhea (51.0%), constipation (16.3%), and nausea (16.3%). Interestingly, in the patients receiving subcutaneous BTZ, the rates of grade 3/4 diarrhea (11.6%), thrombocytopenia (48.8%), anemia (14.0%), and neutropenia (11.6%) were lower than those seen with intravenous BTZ administration in the phase 3 PANORAMA 1 trial (25%, 57%, 16.8%, and 24.1%, respectively). Two patients died while on treatment; one due to disease progression and the other due to infection. Common serious AEs included diarrhea (12.2%) and thrombocytopenia, atrial fibrillation, infection, pneumonia, and syncope (all 6.1%); serious AEs of atrial fibrillation and syncope were higher than in PANORAMA 1 (1.0% and 1.3%, respectively). AEs led to PAN, BTZ, and Dex dose adjustment in 36.7%, 42.9%, and 16.3% of patients, respectively; the most common AE leading to dose adjustment or temporary interruption was thrombocytopenia (all-grade, 30.6%; grade 3/4, 28.6%). Efficacy data will be reported after sufficient follow-up. Conclusions: Overall, the safety results from panobinostat-ETP, albeit in an older population of patients with more advanced MM, support those generated in PANORAMA 1, with only a slight increase in atrial fibrillation, potentially because of the older population. In the subgroup of patients receiving subcutaneous BTZ, rates of diarrhea and hematologic toxicities, AEs of interest with PAN+BTZ+Dex therapy, appear to be reduced compared with PANORAMA 1 data with intravenous BTZ administration; however, because of the small size of this study, these results should be interpreted with caution. Further clinical experience with the use of subcutaneous BTZ in this combination will help to determine the potential impact of the route of BTZ administration on tolerability.

Bridging Strategy

Background: CD19-targeted chimeric antigen receptor T cell (CAR T) therapies have remarkable overall response rates (ORR) for relapsed diffuse large B cell lymphoma (DLBCL). There is strong rationale to use a radiotherapy (RT) bridge during the cell manufacturing process including palliation, local control and cytoreduction with limited count impact. Recent data from our institution suggests RT may augment an immune response and sensitize antigen negative cells to CAR-mediated death. This series details our early experience using RT conditioning. Methods: 13 patients (median age 64 years) with DLBCL (n=9) or transformed follicular lymphoma (n=4) were analyzed. Overall, patients had a median of 2 prior therapies (range 1-8) including 3 with autologous transplant, 3 with distant RT and 1 with CAR T infusion. Several CAR products were used, including axicabtagene ciloleucel (n=8), JCAR017 (n=3, per NCT02631044), tisagenlecleucel (n=1) and EGFRt/19-28z/4-1BBL "armored" CAR (n=1, per NCT03085173). Most patients (n=10) began RT post apheresis with median duration between RT and CAR infusion of 20d (range 13-80, Figure 2). The most common RT regimen (n=8) was 20 Gy in 5 fractions (range 20-47 Gy) but 2 received our pre-transplant regimen of 30 Gy in 20 BID fractions. None received concurrent chemotherapy with RT but one had a cycle post RT and pre CAR. All had cyclophosphamide and fludarabine lymphodepletion. PET response was evaluated by Lugano criteria. Results: Three patients had limited stage PET avid disease at RT and were treated comprehensively pre-CAR. The remaining 10 were advanced stage and were treated palliatively to limited sites. Irradiated sites included the pelvis/groin (n=4), neck (n=3), intraabdominal (n=2) and extremity (n=2). Most (n=10) had intensity modulated radiotherapy. RT fields were large (median planning treatment volume of 887 cc, range 163-1641). Post RT PET interpretation was challenging given a short interval since RT ended (median 11d) but of 11 evaluable patients, many (n=8, 73%) had partial response (PR). Though locally controlled, most (n=10, 91%) had out of field progressive disease (PD) pre-CAR. Post CAR T, no severe adverse events in the RT field were noted, 9/13 had cytokine release syndrome (n=1 grade 3, n=2 grade 2) and 4 had neurotoxicity (n=3 grade 3). At day 30, ORR was 90%; of 10 evaluable patients, 7 had complete response (CR) and 2 had partial response (PR). Of the 7 evaluable patients at day 90, 4 (57%) had continued CR and the other 3 (43%) had PD and subsequently died from DLBCL. One relapsed at 95d post armored CAR both in and out of the RT field, and the other relapsed at 64d post JCAR017 primarily out of field. Conclusions: Use of RT as a CAR T bridging strategy is feasible and associated with excellent pre-CAR local control and initial post CAR ORR in a cohort of heavily pre-treated DLBCL patients. We observed moderate serious CAR toxicity that did not appear to be augmented by RT. Future efforts should clarify the optimal RT timing/dose and assess the potential for incremental immunogenicity with combined therapy.

Abstract Background: Axi-cel is a US FDA-approved autologous anti-CD19 chimeric antigen receptor (CAR) T cell therapy for treatment of adult patients (pts) with relapsed or refractory large B cell lymphoma after ≥ 2 prior lines of therapy. In ZUMA-1, the pivotal study of pts with refractory large B cell lymphoma, the objective response rate (ORR) was 82%, including a 58% complete response (CR) rate (Neepalu and Locke, et al. N Engl J Med. 2017). Grade ≥ 3 cytokine release syndrome (CRS) and neurologic events were observed in 12% and 31% of pts, respectively, and were generally reversible. Checkpoint proteins, such as PD-1 and PD-L1, have been shown to be expressed on both CAR T cells and in the tumor microenvironment and subsequently upregulated after CAR T cell infusion (Vranic, et al. PLoS One. 2017; Cherkassky, et al. J Clin Invest. 2016; Galon, et al. ASCO 2017. #3025). This suggests that axi-cel activity could be augmented by incorporating PD-L1 blockade. This end of Phase 1 analysis of ZUMA-6 examines the safety and preliminary efficacy of axi-cel in combination with the anti-PD-L1 antibody atezolizumab (atezo) in pts with refractory diffuse large B cell lymphoma (DLBCL; NCT02926833). Methods: Eligible pts (≥ 18 years) with refractory DLBCL, defined as stable or progressive disease to last line of therapy or relapse within 12 months after autologous stem cell transplant, must have recieved prior CD20-targeting and anthracycline-containing regimen and had ECOG ≤ 1 and adequate bone marrow and organ function. Pts received low-dose conditioning with fludarabine 30 mg/m2/day and cyclophosphamide 500 mg/m2/day × 3 days followed by axi-cel infusion at a target dose of 2 × 106 cells/kg. Atezo was administered at 1200 mg every 21 days for 4 doses starting on Day 21, 14, and 1 post-axi-cel infusion for Cohorts 1, 2, and 3, respectively. This report describes Phase 1 results from all 3 cohorts. Incidence of dose-limiting toxicities (DLTs) was the primary endpoint. Secondary endpoints included the frequency of adverse events (AEs), disease response, pharmacokinetics, and biomarkers. Results: As of January 19, 2018, 12 pts have received axi-cel and at least 1 dose of atezo (3 in Cohort 1; 3 in Cohort 2, 6 in Cohort 3). Median age was 55 years (range, 30 - 66). Most pts (9/12, 75%) had received ≥ 3 prior therapies, and 4 pts (33%) had an International Prognostic Index score of 3 or 4. The median follow-up from axi-cel infusion was 4.4 months (range, 0.8 - 12.6), with 50% of pts having ≥ 6 months of follow-up. Eight pts (67%) have received all 4 doses of atezo, and 11/12 pts have received all scheduled doses of atezo. One pt in Cohort 3 experienced a DLT of Grade 4 thrombocytopenia and neutropenia lasting longer than 30 days. All pts experienced at least 1 AE (92% Grade ≥ 3), with no apparent exacerbation or recurrence of axi-cel-related toxicity following atezo infusion. Only 1 Grade ≥ 3 AE was attributed solely to atezo. Overall, the most common grade ≥ 3 AEs were anemia (9/12, 75%), encephalopathy (5/12, 42%), and neutropenia (5/12, 42%). Grade ≥ 3 CRS and neurologic events occurred in 3 (25%) and 6 (50%) pts, respectively. The ORR in evaluable pts was 9/10 (90%), with 6 pts (60%) in CR and 3 (30%) in partial response (PR); 2/6 pts (33%) had converted to CR at month 6 and month 9 after initially achieving a PR. CAR T cell expansion as measured by area under the curve in the first 28 days (AUC0-28) was over 2-fold higher in ZUMA-6 than the median observed in pts with DLBCL in ZUMA-1 (ZUMA-6: median, 823 cells/µL × days, range, 99 - 2301; ZUMA-1: median, 357 cells/µL × days, range, 5 - 11,507; Figure). Median CAR T cell levels remained higher than ZUMA-1 beyond 28 days. However, initial peak CAR T cell levels were similar (ZUMA-6: median, 68 cells/µL, range, 9 - 274; ZUMA-1: median, 32 cells/µL, range, 1 - 1513). Interferon-γ (IFNγ) levels peaked within the first week after axi-cel infusion and reached a median of 730.5 pg/mL (range, 212 - 1876). The median peak IFNγ level in pts from ZUMA-6 was 1.5-fold higher than that from pts enrolled in Cohort 1 of ZUMA-1 (493.8 pg/mL, range, 32.4 - 1876). Conclusions: PD-L1 blockade with atezo following axi-cel infusion has a manageable safety profile, with a low incidence of DLTs and no clinically significant evidence of increased incidence of AEs. Encouraging efficacy results support the opening of Phase 2 of ZUMA-6 in which 22 pts will be treated according to the Cohort 3 schedule. Pharmacokinetic data suggest the potential for enhanced CAR T cell expansion. Figure. Figure.

Abstract INTRODUCTION: R-CHOP is effective for diffuse large B-cell Lymphoma (DLBCL), but many patients (Pts) relapse or have refractory disease, likely due to inherent biologic differences in DLBCL subtype. Activated B-Cell (ABC) subtype DLBCL signals through Nuclear Factor-κ-B (NF-κB) and is more likely to display treatment failure than DLBCL arising from the germinal center (GC). Proteasome inhibitors disrupt NF-κB signaling, but randomized trials have failed to demonstrate clinical benefit of adding bortezomib to R-CHOP for the treatment of non-GC DLBCL. Carfilzomib (Car) displays superior clinical activity relative to bortezomib in plasma cell neoplasms and, while occasionally associated with cardiac events, does not have dose-limiting neuropathy. To explore the safety and efficacy of Car in upfront treatment of DLBCL, we initiated a phase I/II clinical trial of Car + R-CHOP and report the phase I results. METHODS: 24 adult (age ≥ 18) Pts with untreated de novo or transformed DLBCL, adequate organ function and performance status were enrolled. During 3 x 3 dose escalation, Car was given at 20 mg/m2 on days 1 and 2, with R-CHOP on day 2 for 6 cycles (n = 6). Due to grade 4 thrombocytopenia, the protocol was amended to administer Car at a dose (in mg/m2) of 20 on days 1 and 2 of cycle 1 with rituximab (R) on day 2 and CHOP on day 3, followed by a Car dose of 20 (n=3), 27 (n=3), 36 (n=3), 45 (n=3) and 54 (n = 6) on days 1 and 2 of cycles 2-6. All Pts received pegfilgrastim the day after CHOP and zoster prophylaxis with acyclovir x 6 months post treatment. Echocardiograms were obtained at baseline and at conclusion of therapy to assess the cardiac safety of combining Car with anthracycline. Interim response assessments with CT +/- PET were performed after cycle 3 and end-of-treatment response assessments were uniformly captured with PET. RESULTS: The median age was 57 (range 24-77) years old. 63% of patients were female. Stage at diagnosis was I-II (58%) or III-IV (32%). The majority of Pts had ECOG performance status of 0-1 (88%). B symptoms were present in 21% of Pts and 54% had an increased LDH at diagnosis. 29% had >1 extranodal site. IPI score was 0-1 (50%), 2 (21%) or 3-4 (39%). For this phase I dose escalation study, eligible Pts included primary mediastinal lymphoma (n = 1) and DLBCL of GC (n = 9), non-GC (n = 13) and unknown (n = 1) Hans algorithm subtypes. Hematologic adverse events (AEs) included 60 grade 1/2, 27 grade 3 and 16 grade 4 AEs. Grade 3/4 hematologic toxicities included neutropenia (n=14), thrombocytopenia (n = 6) anemia (n = 6), with only 4 cases of grade 3 febrile neutropenia. Grade 3/4 non-hematologic AEs were generally consistent with known R-CHOP toxicity were notable for: hypertension (n = 2), decreased ejection fraction (n =2), GI hemorrhage (n = 2) dizziness, headache, and syncope (n = 1 each), thromboembolic event (n=1), hyperglycemia (n=2), increased ALT (n=1) and nausea/vomiting (n=2). Compared to age-matched controls, end-of-treatment echocardiograms of CarR-CHOP treated Pts showed no statistically significant additional effect on ejection fraction (EF) [94.8% vs. 90.0% of pre-treatment value, respectively (P = 0.19)] after 6 cycles of treatment and there was no association of change in EF with Car dose (P = 0.61). There were no dose limiting toxicities. As of June 2018, median follow-up among surviving Pts was 16 months. There were 3 deaths during the study period, 2 from lymphoma and 1 from lung cancer. The overall response rate was 92% [75% complete remission (CR), 17% partial remission]. 18-month Kaplan Meier estimates of PFS and overall survival were 77% and 88%, respectively (Figure). There was no significant difference in CR rates or PFS for patients with GC vs. non-GC subtype (P = 0.65 and 0.61, respectively). CONCLUSION: CarR-CHOP is safe at a recommended phase II dose of 20 mg/m2 on day 1 & 2 for cycle 1 followed by 56 mg/m2 for cycles 2-6, without significant excess cardiac effects. Within the limitations of a prospective phase I clinical trial with potential patient selection bias, preliminary efficacy data suggest a high complete metabolic response rate and equivalent outcomes for patients with GC and non-GC subtype. Phase II accrual is ongoing for non-GC DLBCL only and additional correlative studies of the molecular subtype of DLBCL will be incorporated into future analysis.

Background: In the two largest phase 3 studies in patients with paroxysmal nocturnal hemoglobinuria (PNH), ravulizumab given every 8 weeks was noninferior to eculizumab given every 2 weeks across all efficacy endpoints. Data on efficacy and safety of ravulizumab in patients aged >65 years with PNH are limited. Aims: To compare the efficacy and safety of ravulizumab in patients with PNH aged >65 years with those aged ≤65 years. Methods: The population included patients from two phase 3 studies that assessed ravulizumab vs eculizumab in complement-inhibitor-naïve (301; NCT02946463) and -experienced (302; NCT03056040) adults with PNH. In study 301, patients were aged ≥18 years with a confirmed PNH diagnosis by flow cytometry and had a lactate dehydrogenase (LDH) level ≥1.5x upper limit of normal (ULN; 246U/L). In study 302, patients were aged ≥18 years with a confirmed PNH diagnosis by flow cytometry, were clinically stable on eculizumab having received ≥6 months of treatment and had a LDH level ≤1.5x ULN. Patients were randomized to either ravulizumab or eculizumab for 26 weeks after which all received ravulizumab up to 52 weeks. This prespecified analysis stratified patients by age: ≤65 or >65 years. Primary endpoints included percentage change in LDH from baseline to weeks 26 and 52, percentage of patients achieving LDH-normalization (LDH-N; LDH levels: ≤1x ULN) at weeks 26 and 52 and transfusion avoidance (TA) from baseline to weeks 26 and 52. Breakthrough hemolysis (BTH), hemoglobin (Hgb) stabilization and FACIT-fatigue score were secondary endpoints. Treatment emergent adverse events (TEAEs) were assessed as an indicator of safety. Results: A total of 58 patients aged >65 years and 383 patients aged ≤65 years were included. Disposition and medical history were similar among subgroups at baseline (Table 1). Results for primary and secondary endpoints for the two subgroups were comparable across studies and efficacy was maintained through 52 weeks. A higher proportion of treatment-experienced patients (>65 years) achieved all endpoints vs -naïve patients (Table 2). The percentage change in LDH levels from baseline to 26 and 52 weeks was similar between subgroups in study 301 (-66.5 to -80.0%) whereas in study 302, LDH levels remained stable in all subgroups up to 52 weeks (-3.7 to 22%). The percentage of patients achieving LDH-N in both studies at 26 and 52 weeks differed; 43.8-63.9% of patients aged ≤65 years achieved LDH-N compared with 21.4-77.8% of patients aged >65 years. A higher proportion of older treatment-experienced patients (57.1‒77.8%) achieved LDH-N compared with older treatment-naive patients (21.4‒50.0%) at 26 and 52 weeks. In patients aged ≤65 years in both studies, 63.7‒89.4% achieved TA. In the >65 years subgroup, 14.3‒50.0% of treatment-naive patients achieved TA whereas in study 302, 54.5‒72.7% of patients achieved TA. The number of BTH events was low, with no events reported in older patients to date. Hgb stabilization was consistent in the ≤65 year subgroup between the studies; a higher proportion of older patients in study 302 (45.5‒71.4%) achieved stabilized Hgb compared with older patients in study 301 (14.3‒35.3%). A clinically significant 3-point change was seen in FACIT-fatigue scores (indicating improvements in fatigue), with higher scores observed for ravulizumab in both subgroups (Figure 1). One patient discontinued the extension of study 301 due to lung cancer onset during the 26-week period and died following discontinuation. Headache was the most frequent TEAE. The incidence of TEAEs reported during ravulizumab treatment up to 52 weeks did not increase vs the 26-week period, with few events (Table 3) and no difference between subgroups. Conclusions: We present clinical outcomes in the largest cohort of patients with PNH (>65 years) on ravulizumab in a clinical trial setting to date. Ravulizumab was associated with similar efficacy and safety in both age subgroups and showed consistent and durable efficacy through 52 weeks of treatment. A higher proportion of patients in study 302 achieved all efficacy endpoints than in study 301, which can be due to patients' prior complement inhibitor experience. This observation was more evident in older patients. There were no BTH events in the older patients to date, and the number of infections in both subgroups was low. Ravulizumab was well tolerated in older patients with no additional safety concerns compared to younger patients.

Abstract Abstract 301 Background: Pomalidomide (POM) is an IMiD® derived from thalidomide with a modified chemical structure with improved potency in vitro and potential efficacy and safety benefits in vivo. Two phase (Ph) 1b, single-center, ascending dose, open-label studies in pts with relapsed/refractory multiple myeloma (MM; Schey et al, 2004, Streetly et al, 2008) identified maximum tolerated dose (MTD) as 2mg QD or 5mg on alternate days (28 of each 28-day cycle). High response rates of POM alone in heavily pretreated pts were encouraging. To evaluate the MTD, safety and efficacy of POM alone or with Dexamathasone (dex) on a 21/28 day schedule, a Ph 1/2, multicenter, randomized, open-label, 3×3 dose-escalation study was initiated in pts with relapsed/refractory MM after at least 2 prior regimens, including bortezomib and lenalidomide. Methods: The study has a Ph 1 POM MTD (n=32) portion, followed by Ph 2 open-label randomized POM+ dex vs POM alone (192 pts planned). Eligible pts had documented relapsed/refractory MM. All pts received low-dose prophylactic aspirin QD and monitored for venous thromboembolic events (VTE). In Ph 1, POM was given QD on Days 1–21 of 28-day cycle: 4 dose levels of POM (2, 3, 4, 5mg) were studied with option to add dex at 40 mg/wk after 4 cycles for lack of response or progressive disease (PD). Pts enrolled in Ph 1 and discontinued either for intolerance or PD could not be enrolled in Ph 2. Toxicities and responses were assessed using CTCAE v3 and modified European Group for Blood and Marrow Transplantation (EBMT) criteria. Results: Results from Ph 1 of the study are reported with 32 pts enrolled to date. Fifteen pts discontinued therapy and 17 pts are ongoing for both safety and efficacy analyses. Mean age is 66.6 yrs (range 38–84), with median number of prior regimens 7 (range 2–18). MTD has not yet been reached. There were 4 dose reductions due to POM (5mg [2-neutropenia, 1-rash]; 3mg [1-neutropenia]) after 108 completed cycles. Neutropenia and thrombocytopenia were the most common grade 3/4 toxicities, with no dose-dependent increase apparent so far: 12 serious adverse events (SAEs) occurred in 10 pts; drug related events included POM (VTE, syncope, 3rd degree AV block, asthenia, diarrhea, neutropenia, anemia, rash); dex (lung infection with neutropenia); POM + dex (sepsis with pharyngeal abscess). AEs such as somnolence (1) VTE (1) neuropathy (2), and constipation (4) were uncommon. There were 3 deaths on study not attributed to POM; 2 pts died of rapid PD, 1 pt died of gastrointestinal perforation due to amyloidosis. Responses were seen at each dose level (Table 1). In 20/21 (95%) evaluable pts, clinical activity (SD or better) was reported. During treatment with POM alone, overall response rate (ORR; 1 CR, 2 PR, 5 MR) was 38% (8/21), mean duration of response (DOR) was 11.1 (range 4–32) wks, mean time to progression (TTP) was 8.3 (range 2–36) wks. Median completed cycles of POM +/− dex overall was 4 (range 1–12), with 13/21 evaluable pts (62%) having dex added to their regimens at various different cycles (median cycle 3, range 2–9) for PD or lack of response. During treatment with POM+dex, ORR (2 PR, 3 MR) was 38%, mean DOR of 14.2 (range 4–32) wks, and mean TTP of 20 (range 4–52) wks. In addition, there were 9 stable diseases (SD) on POM alone with mean DOR of 7.1 (range 4–16) wks, and 6 SD on POM + dex with mean DOR of 10.7 (range 8–16) wks. In 5/13 pts (38%), responses improved after dex was added (2 PR, 2 MR, 1 SD). Conclusions: These preliminary results indicate that POM alone or in combination with dex is associated with 38% MR or better, while SD was achieved in 43% (POM alone) and 46% (POM + dex), amongst heavily pretreated pts with relapsed/refractory MM. The incidence of SAEs and discontinuations decreased with increased dose of POM with no dose-dependent increase in grade 3/4 hematological toxicities. The MTD has not been reached to date. Overall, these data indicate that POM has an acceptable safety profile and is a clinically active therapeutic option for advanced refractory MM, warranting further investigation in this patient population.

Abstract Background Ruxolitinib is a potent JAK1/JAK2 inhibitor that has demonstrated rapid and durable reductions in splenomegaly, improved MF-related symptoms and quality of life (QoL), and prolonged survival in 2 phase 3 studies comparing ruxolitinib with placebo (COMFORT-I) and best available therapy (COMFORT-II). However, no clinical trial in pts with MF had been conducted in Asian countries, and only a limited number of Asian pts or healthy volunteers had been enrolled in any ruxolitinib study. Methods This study was an open-label phase 2 study evaluating ruxolitinib in Asian pts with PMF, PPV-MF, or PET-MF who had palpable splenomegaly ≥ 5 cm below the costal margin and intermediate-2– or high-risk MF by the International Working Group for Myelofibrosis Research and Treatment (IWG-MRT) criteria. Pts received starting doses of ruxolitinib 15 or 20 mg twice daily (bid) based on baseline platelet count (100-200 or > 200 × 109/L, respectively); dose adjustments balancing safety and efficacy were allowed to titrate each pt to their most appropriate dose. The primary endpoint was met if the proportion of pts achieving ≥ 35% reduction in spleen volume from baseline at week 24 was ≥ 27.5% as measured by MRI/CT. Symptomatic response was assessed as a secondary endpoint using the 7-day modified MF Symptom Assessment Form (MFSAF) v2.0 total symptom score (TSS) and European Organisation for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC QLQ-C30). The study was conducted in China (n = 63), Japan (n = 30), Korea (n = 17), and Taiwan (n = 10). The data cutoff date for this analysis was 7 June 2013. Results Overall, 120 pts were enrolled (PMF, n = 80; PPV-MF, n = 21; PET-MF, n = 19), and their baseline characteristics were as follows: median age, 61 years (range, 25-80 years); 51.7% female; 69.2% intermediate-2 and 30.8% high risk by IWG-MRT criteria; median palpable spleen size, 15 cm (range, 5-45 cm); median spleen volume, 2159 cm3; 55.8% of pts had prior exposure to hydroxyurea. The median follow-up was 8.44 months; 22.5% of pts discontinued treatment, primarily for adverse events (AEs; 9.2%) and disease progression (7.5%). The median duration of treatment was 8.44 months (range, 0.5-21.7 months), and the median daily dose was 20.64 mg/day in the 15 mg bid group (n = 46) and 36.11 mg/day in the 20 mg bid group (n = 74). All pts were evaluable for achievement of the primary endpoint, 101 pts remained on study and were evaluable at week 24, and 96 pts had nonzero scores on the MFSAF-TSS and were evaluable for a reduction from baseline. Most pts who had assessments at week 24 (91% [92/101]) had a reduction from baseline in spleen volume (Figure). The study met the primary endpoint, with 31.7% (38/120) of all pts achieving ≥ 35% reduction from baseline at week 24. Overall, 38.3% (46/120) of pts achieved ≥ 35% reduction from baseline in spleen volume at any time on study. As measured by the 7-day MFSAF, 49% (47/96) of pts achieved ≥ 50% reduction from baseline in TSS (median reduction, 47.2%). Pts experienced an improvement from baseline at week 24 in EORTC global health status/QoL (mean change, 5.2). The most common nonhematologic AEs (≥ 10%) regardless of relationship to study medication included diarrhea (25.8%), upper respiratory tract infection (17.5%), ALT level increased (15.0%), pyrexia (15.0%), AST level increased (13.3%), cough (11.7%), herpes zoster infection (11.7%), nasopharyngitis (10.8%), constipation (10.0%), gamma-glutamyl transferase level increased (10.0%), and headache (10.0%), and most were grade 1/2. Serious AEs were reported for 24.2% of pts, and 65.8% of all pts had grade 3/4 AEs. The most common new or worsening laboratory abnormalities were low hemoglobin (all grade 3, 55.7%), low lymphocyte (grade 3/4, 19.5%), low platelet (grade 3/4, 15.3%), and low ANC (grade 3/4, 7.6%) levels. AEs observed in this study were consistent with those observed in the 2 large phase 3 COMFORT studies. Six pts (5%) died on treatment or within 30 days of discontinuation. Summary/conclusions Findings from this study demonstrated that ruxolitinib was relatively well tolerated in Asian pts with MF and provided substantial reductions in splenomegaly and modest improvements in MF-associated symptoms. The AEs observed with ruxolitinib treatment in this study are consistent with those observed in the large phase 3 COMFORT studies, and there were no new AEs associated with ruxolitinib in Asian pts with MF.

Abstract Background Polycythemia vera (PV) is the most common of the myeloproliferative neoplasms and is characterized by elevated hematocrit requiring phlebotomy, splenomegaly, a variety of symptoms and increased thrombotic risk. Ruxolitinib, a JAK1/JAK2 inhibitor, was well tolerated and achieved rapid and durable clinical responses in a phase 2 study of patients (pts) with PV who were resistant to or intolerant of hydroxyurea (HU). Pts experienced phlebotomy independence, resolution of splenomegaly, and improvements in white blood cell (WBC) counts, platelet (PLT) counts, and disease-related symptoms. Here, we describe the baseline (BL) characteristics and symptom burden of pts in a phase 3 study of ruxolitinib in pts with PV who are resistant to or intolerant of HU. Methods RESPONSE is a randomized (1:1), open-label, phase 3 study (NCT01243944) comparing the efficacy and safety of ruxolitinib with best available therapy (BAT) in pts with PV who are resistant to or intolerant of HU (modified European LeukemiaNet criteria), have splenomegaly, and require phlebotomy for inadequate hematocrit (Hct) control. Fourteen disease-related symptoms were assessed on a scale of 0 (absent) to 10 (worst imaginable) using the modified Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF). Blinded data are presented here. Results BL demographic data are available for the 222 enrolled pts (Table). Apart from HU, other common prior medications for PV included interferons (15%), PLT aggregation inhibitors (10%), alkylating agents (3.6%), alkyl sulfonates (3.2%), pyrimidine analogues (1.8%), and nitrosoureas (1.4%). The majority of pts (54.5%) had 1 phlebotomy within 12 weeks prior to screening; 23.9% had 2 and 17.1% had 3 or more phlebotomies. RESPONSE BL demographics are generally similar in terms of age (60 years vs 57-67); sex (66% male vs 58%-68%); Hct (44% vs 45%-48%); and platelets (419 x 109/L vs 320-429 x 109/L) to other PV studies including trials of givinostat (Finazzi BJH 2013) and AOP2014 (Gisslinger ASH 2012) and the ECLAP-PV (Marchioli JCO 2005) and CYTO-PV studies (Marchioli NEJM 2012). At the time of writing, BL symptom data from the MPN-SAF were available for 164 pts (Table). Pts in this study reported a similar symptom burden as PV pts from a large study of pts with MPNs (Emanuel JCO 2012; N = 1425; PV, n = 538), including similar mean scores for early satiety, abdominal discomfort, concentration problems, night sweats, itching, and tiredness/fatigue. In addition, prior therapy may have adversely affected BL symptom burden, as many of these symptoms (concentration problems, night sweats, fatigue) have been shown to be worsened by the use of conventional therapy to strictly control Hct (< 45%) and cardiovascular risk (Emanuel EHA 2013). BL MPN-SAF symptom data for all 222 pts will be presented. In addition, correlations between BL EORTC QLQ-C30 and MPN-SAF scores will be presented. Summary/Conclusions Demographic and BL symptom data from the RESPONSE study demonstrated that pts with HU refractory or intolerant PV have a significant disease burden that includes a variety of symptoms. These findings are consistent with those of Emanuel (JCO 2012), which showed that pts with PV have a significant symptom burden and a reduced quality of life. Pts with PV in the RESPONSE study are representative of those who have been studied in other clinical trials for the treatment of PV.
