Introduction Hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS), is a rare and potentially life-threatening complication of hematopoietic stem cell transplantation (HSCT). Severe cases, historically defined by multi-organ dysfunction (MOD), may be associated with mortality rates of >80%. There is no FDA-approved treatment for VOD/SOS. Defibrotide (DF) has a proposed mechanism of action that includes stabilization of endothelial cells and restoration of thrombo-fibrinolytic balance. Earlier analyses of a pivotal phase 3 trial of DF in VOD/SOS plus MOD (Richardson et al. Blood. 2009;114:Abstract 654) underpinned approval of DF in the EU to treat severe hepatic VOD/SOS after HSCT. Additional data were obtained at the request of US health authorities. Here we present the final analysis: day +100 survival (primary endpoint) and complete response (CR; secondary). Methods This was a multicenter, open-label, phase 3 historical control (HC) study assessing DF. Eligible patients met Baltimore VOD/SOS criteria (total bilirubin ≥2.0 mg/dL with ≥2 of: hepatomegaly, ascites, or 5% weight gain) by day +21 post-HSCT, plus MOD (renal [trebling of creatinine levels, reduced creatinine clearance, or dialysis] and/or pulmonary [oxygen saturation ≤90%, need for oxygen supplementation/ventilator dependence]) by day +28 post-HSCT. Exclusion criteria included severe graft-versus-host disease (GvHD) of liver or gut, clinically significant bleeding, or need for ≥2 pressors. HC patients were reviewed for inclusion/exclusion criteria in a sequential review of medical charts starting 6 months prior to use of DF at each site; a blinded medical review committee made the final determination of HCs unequivocally meeting criteria for VOD/SOS with MOD. DF dose was 25 mg/kg/d in 4 divided 2-hour IV infusions q6h; recommended treatment duration was ≥21 days. Primary endpoint was day +100 survival. CR by day +100 was a secondary endpoint. Treatment difference in survival and CR rates and their 95% confidence intervals were estimated using propensity-stratified and weighted (Koch-adjusted) estimates of differences in proportions that account for baseline prognostic factors of survival (ie, ventilator and/or dialysis dependency at entry, age ≤/>16 years, transplant type, and prior HSCT). Analyses included patients treated with DF and HCs. Results There were 102 patients in the DF group and 32 cases selected as HCs. Baseline characteristics were similar in the DF and HC groups: mean age (26 and 25 years; 43% and 44% ≤16 years), allogeneic graft (88% and 84%), prior HSCT (13% and 9%), ventilator- and/or dialysis-dependent at study entry (33% and 22%), myeloablative conditioning (87% and 94%), and the most common underlying diseases (acute leukemias: 45% and 47%), respectively. In the DF-treated group, common GvHD medications included tacrolimus (49%), methotrexate (41%), and cyclosporine (38%); in the HC group, common medications were cyclosporine (72%) and methotrexate (63%). Survival at day +100 in the DF and HC groups was 38% and 25%, respectively. The propensity-stratified difference in survival was 23.0% (95.1% CI, 5.2-40.8, P = .0109). Respective observed CR rates by day +100 were 25.5% and 12.5%, and the propensity-stratified difference in CR was 19.0% (95.1% CI, 3.5-34.6, P = .0160). Comparing the earlier EU and final analyses, the survival rates at day +100 in each group did not vary; however, the propensity adjusted final analysis provided a different level of statistical significance. Day +100 CR rates in the original analysis were slightly lower in both arms at 24% and 9% due to increased data capture to investigate CR; the P value was essentially unchanged. For the DF group, 45% had an adverse event (AE) at least possibly related to study drug, and 21% had a serious AE at least possibly related to study drug. In this very sick population, percentages of patients with ≥1 AE leading to death were similar between DF and HC patients (64% and 69%), as were hemorrhagic AEs (64%, 75%) and hypotension (39%, 50%). Conclusions Based on observed study data and using a propensity-adjusted rate difference estimator, patients treated with DF had a 23% reduction in risk of death by day +100 and 19% improvement in CR rate. Overall incidence of hemorrhage and fatal AEs were similar between groups with AEs consistent with those expected in this critically ill population. Support: Jazz Pharmaceuticals.

Abstract Introduction: Panobinostat is a potent pan-deacetylase inhibitor (pan-DACi) that targets key aberrations in multiple myeloma (MM) cell biology, including epigenetics and protein metabolism. In the phase 3 clinical trial PANORAMA 1, panobinostat in combination with bortezomib and dexamethasone (PAN-BTZ-Dex) led to a statistically significant and clinically relevant increase in progression-free survival of approximately 4 months compared with that with placebo plus bortezomib and dexamethasone (Pbo-BTZ-Dex). Further analyses of patient outcomes by prior treatment demonstrated that the magnitude of PFS benefit was greatest among patients who received at least 2 prior regimens, including bortezomib and an immunomodulatory drug (IMiD; PAN-BTZ-Dex [n = 73]: 12.5 months [95% CI, 7.3-14.0 months]; Pbo-BTZ-Dex [n = 74]: 4.7 months (95% CI, 3.7-6.1 mo; HR 0.47 [95% CI, 0.32-0.72]). These data supported the regulatory approvals of PAN-BTZ-Dex for the treatment of patients with multiple myeloma who received at least 2 prior regimens, including bortezomib and an IMiD. Here we present the final analysis of overall survival (OS) for the entire patient population and among patients who received at least 2 prior regimens, including bortezomib and an IMiD. Methods: The study design for the PANORAMA 1 trial was described previously (San-Miguel. Lancet Oncol. 2014;15:1195-206). The key secondary endpoint was OS. As of June 29, 2015, the 415 events required to conduct the final analysis of OS had been observed. Kaplan-Meier estimation was utilized for OS analyses for the entire population (N = 768), the pre-specified subgroup of patients who received prior bortezomib and IMiD (n = 193), and patients who received at least 2 prior regimens including bortezomib and an IMiD (n = 147). Results: The median OS of patients who received PAN-BTZ-Dex in the overall population was 40.3 months (95% CI, 35.0-44.8 months) vs 35.8 months (95% CI, 29.0-40.6 months) for the Pbo-BTZ-Dex arm with HR 0.94 [95% CI, 0.78-1.14], P = .5435 (Fig 1A). The percentage of patients in each arm who received post-study therapy was 37.7% in the PAN-BTZ-Dex arm and 48.8% in the Pbo-BTZ-Dex arm. The median OS of patients who received at least 2 prior lines, including bortezomib and an IMiD, was 25.5 months (95% CI, 19.6-34.3 months) in the PAN-BTZ-Dex arm vs 19.5 months (95% CI, 14.1-32.5 months) in the Pbo-BTZ-Dex arm (Fig. 1B). The proportion of patients in this subgroup who received post-study therapy was 35.6% in the PAN-BTZ-Dex arm and 66.2% in the Pbo-BTZ-Dex arm. Conclusion: For the overall PANORAMA 1 study population, patients in the PAN-BTZ-Dex arm demonstrated an increase in median OS of 4.5 months vs patients in the Pbo-BTZ-Dex arm, but this result was not statistically significant (P = .5435). Median OS was also slightly longer for the PAN-BTZ-Dex arm among the more heavily pretreated subgroup of patients who received at least 2 prior regimens, including bortezomib and an IMiD. A higher percentage of patients on the Pbo-BTZ-Dex arm received post-study therapy vs the PAN-BTZ-Dex arm, which may have confounded the OS results. In summary, PAN-BTZ-Dex demonstrates statistically significant increases in PFS vs Pbo-BTZ-Dex in patients with relapsed or relapsed and refractory MM; however, this did not translate to a statistically significant increase in OS. Future trials will plan to focus on further optimization of dose and schedule of panobinostat and bortezomib to improve outcome, as well as novel combinations with other agents, including IMiDs and next-generation proteasome inhibitors.

Abstract Introduction Hepatic veno-occlusive disease, also called sinusoidal obstruction syndrome (VOD/SOS), is an unpredictable, potentially life-threatening complication of conditioning regimens for hematopoietic stem cell transplant (HSCT). Although VOD/SOS usually is thought of as a complication of HSCT, there is also a known risk in patients following chemotherapy in a non-HSCT setting. Severe hepatic VOD/SOS (ie, with multi-organ dysfunction [MOD]), may be associated with >80% mortality. Endothelial cell (EC) damage is a critical factor in the pathophysiology of VOD/SOS. Preclinical data suggest that defibrotide stabilizes ECs with direct, as well as EC-mediated, restoration of the thrombo-fibrinolytic balance. Defibrotide is approved for treatment of severe hepatic VOD/SOS in adult and pediatric patients in the European Union. In the United States, defibrotide is available as an investigational drug through an ongoing expanded-access protocol for treatment of hepatic VOD/SOS. Methods In the original protocol, patients were eligible if they had hepatic VOD/SOS by Baltimore criteria post-HSCT and MOD, defined by renal (tripling of creatinine levels or reduced creatinine clearance with or without dialysis) and/or pulmonary (need for oxygen supplementation with or without assisted ventilation) dysfunction. Symptoms of VOD/SOS were not considered adverse events (AEs) unless the event was considered serious. The protocol was later amended to include (1) post-chemotherapy patients with hepatic VOD/SOS; (2) patients with hepatic VOD/SOS without MOD, and (3) VOD/SOS per modified Seattle criteria. Enrolled patients received defibrotide 25 mg/kg/d in 4 divided doses for a recommended ≥21 days. Here, we describe efficacy and safety results with defibrotide for the subset of patients that developed VOD/SOS post-chemotherapy. Results Out of 642 patients who developed VOD/SOS and received ≥1 dose of defibrotide, 69 patients received chemotherapy without HSCT; 52% (n=36) had MOD, and 48% (n=33) did not. Median age was 8 years (range, <1 month-58.0 years), and 55 patients (80%) were ≤16 years (39 patients were children aged 2-11); 54% of patients were male. The most common primary diseases were acute lymphocytic leukemia (44%) and acute myelogenous leukemia (10%). Chemotherapeutic agents received by more than 30% of patients were vincristine, cyclophosphamide, cytarabine, doxorubicin, methotrexate and PEG-L-asparaginase. Antibody-drug conjugates linked to ozogamicin that are associated with development of VOD/SOS (gemtuzumab and inotuzumab) were received by 3 and 1 patient, respectively. The Kaplan-Meier estimated day +100 survival rate was 77.4% (95% confidence interval, 65.4%-85.7%). For patients with MOD and without MOD, the Kaplan-Meier estimated day +100 survival rates were 74.3% (56.4%-85.7%) and 80.9% (62.3%-90.9%), respectively. Overall, ≥1 AE was reported in 44 chemotherapy patients (63.8%). Of these, 14 (20.3%) had AEs assessed by the investigator as possibly, probably, or definitely related to defibrotide. Treatment-related AEs occurring in ≥2 patients were hypotension (4.3%), nausea (2.9%), vomiting (2.9%), and epistaxis (2.9%). Hemorrhagic AEs of any severity occurring in ≥2 patients were pulmonary (7.2%), epistaxis (5.8%), and gastric (2.9%). Serious AEs were reported in 26 patients (37.7%), most commonly multi-organ failure (7.2%), hypoxia (5.8%), and pulmonary hemorrhage (5.8%). AEs led to discontinuation in 4 patients (gastric, gastrointestinal and mouth hemorrhages, epistaxis, and hypotension). No treatment-related deaths were reported. Conclusions Day+100 survival of 77.4% in patients developing VOD/SOS following a variety of chemotherapy regimens without HSCT (80% of which were pediatric, primarily children) is a clinically encouraging finding. Defibrotide treatment in this group of 69 patients developing VOD/SOS post-chemotherapy was generally well-tolerated, with only 5.8% of patients discontinuing due to an AE and no treatment-related fatalities.

Abstract Introduction Hepatic veno-occlusive disease, also called sinusoidal obstruction syndrome (VOD/SOS), is an unpredictable, potentially life-threatening complication of conditioning for hematopoietic stem cell transplant (HSCT). Severe VOD/SOS (ie, with multi-organ dysfunction [MOD]) may be associated with >80% mortality. Defibrotide is approved for treatment of severe VOD/SOS in the EU. In the US, defibrotide is available through an ongoing, expanded-access study. The optimal time to initiate VOD/SOS treatment with defibrotide is of interest. Methods In the expanded-access study, patients were eligible in the original protocol if they had VOD/SOS and renal/pulmonary MOD by Baltimore criteria post-HSCT or by biopsy. The protocol was amended to include (1) post-chemotherapy patients, (2) patients without MOD, and (3) VOD/SOS per modified Seattle criteria. Defibrotide 25 mg/kg/day was given in 4 divided doses for a recommended ≥21 days. Here, Day +100 survival in patients with HSCT was examined post hoc based on time from VOD/SOS diagnosis (with or without MOD as relevant to study entry criterion) to initiation of defibrotide. Two analyses were conducted: (1) survival rate analyzed by treatment initiation for the entire population before or after each of the following days: 1, 2, 3, 4, 7, and 14, using Fisher's exact test; (2) survival rate for only those patients with treatment initiated on a particular day: 0, 1, 2, 3, 4, 5, 6, 7, 8-14, and ≥15, with a Cochran-Armitage test for trend across days. Results Among HSCT patients enrolled through 2013 who received ≥1 dose of defibrotide, treatment date was available for 573 patients. Of these, 351 also had MOD. Defibrotide was started on the day of diagnosis in >30% of patients; >90% of patients started defibrotide before day 7 post-diagnosis. In the population-wide analysis of treatment initiation before or after days 1, 2, 3, 4, 7, and 14, earlier initiation of defibrotide was associated with higher survival rates (Table), and was statistically significant for all cut-points considered except 14 days, with only 2.8% of patients beginning treatment post-day 14. Survival differences between earlier vs. later initiation ranged from 8.8% to 22.1% overall (MOD: 12.8% to 25.6%; Table) for the cut-points considered. In the analysis of relationship between Day +100 survival and treatment initiation day, survival rates were generally higher if treatment was initiated earlier. This was demonstrated by a statistically significant trend over time for better outcomes with earlier initiation (Figure). Similar results for both analyses were obtained for all patients with VOD/SOS and for the subgroup of patients with MOD. Conclusions Data indicate decreased Day +100 survival associated with longer treatment delays, confirmed by the Cochran Armitage trend test (P<0.001). Thus, defibrotide treatment should be initiated as soon as possible after VOD/SOS diagnosis. Table.

Abstract Background: Thrombocytopenia occurs in ~50% of patients with low/int-1 risk myelodysplastic syndrome (MDS) and is associated with reduced survival. In a placebo (PBO)-controlled study, 250 patients with MDS were randomized 2:1 to receive weekly romiplostim or PBO. In the original June 2011 analysis, romiplostim reduced clinically significant bleeding events [hazard ratio (HR) romiplostim vs PBO 0.83, 95% CI: 0.66−1.05, P = 0.13] and platelet transfusions (relative risk 0.77, 95% CI: 0.66−0.88, P<0.001) and increased IWG hematologic improvement platelets (HI-P) incidence (odds ratio 15.6, 95% CI: 4.7−51.8, P<0.001). Peripheral blast count increases >10% were more frequent with romiplostim (25/167, 15%) than PBO (3/83, 3.6%) and resolved after discontinuation in most cases. In February 2011, the DMC recommended that treatment with study drug be discontinued as the potential benefit seen in the reduction of bleeding did not outweigh the potential risk for disease progression to AML, and that transient increases in blast cell counts might put patients at risk for diagnosis of and treatment for AML. Patients were moved into long-term follow-up (LTFU). Previously reported (Giagounidis et al, Cancer 2014) 58-week incidence of AML was 6.0% (N = 10) for romiplostim and 4.9% for PBO (N = 4); HR 1.20 (95% CI: 0.38−3.84). This report provides final 5-year LTFU data. Methods: Eligible patients were receiving only supportive care and had IPSS low/int-1 risk MDS and platelets 1) ≤20 × 109/L or 2) ≤50 × 109/L with a history of bleeding. Disease progression to AML was defined as 1) ≥20% blasts in bone marrow or peripheral blood after 4 weeks following discontinuation of romiplostim; 2) pathology consistent with leukemia; or 3) antileukemic treatment. Results are presented by treatment group. Results: At baseline, median (Q1, Q3) age was 70 (61, 77) years, the majority (59%) of patients were male; 27.6% were IPSS low risk and 72.4% were int-1 risk. WHO classifications were RCMD: 67.6%, RAEB-1: 13.2%, MDS-U: 11.2%, RA: 4.4%, RCMD-RS: 2.4%, RARS: 0.8%, and RAEB-2: 0.4%. Of 250 patients in the study, 210 entered LTFU and 66 completed the 5 years of LTFU; median (Q1, Q3) follow-up was 27.5 (10.8, 58.7) months. Reasons for discontinuation (death, lost to follow-up, and consent withdrawal) during LTFU were similar in both groups. During the active study period and LTFU, death was reported in 93 (55.7%) patients in the romiplostim group and 45 (54.2%) patients in the PBO group (HR romiplostim vs PBO 1.03, 95% CI: 0.72−1.47) (Figure); mortality rates were greater in those with IPSS int-1 vs low risk for both groups (Table). AML was reported in 20 (11.9%) patients in the romiplostim group and 9 (11.0%) patients in the PBO group (HR 1.06, 95% CI: 0.48−2.33). The proportions of patients who either died or developed AML were 56.9% (N = 95) in the romiplostim group and 55.4% (N = 46) in the PBO group (HR for AML-free survival 1.04, 95% CI: 0.73−1.48) (Figure). Nearly half (N = 14, 48%) of the 29 AML cases occurred in patients who were RAEB-1 at screening (none RAEB-2), and 6 cases were diagnosed because of anti-AML treatment use alone (Table). In LTFU, patient-reported use of MDS therapy (eg, azacitidine or cyclosporine) was 42.8% (N = 59, 95% CI: 34.4%−51.5%) in the romiplostim group and 31.4% (N = 22, 95% CI: 20.9%−43.6%) in the PBO group. AML therapy (eg, chemotherapy) was used in 14 (10.2%) patients in the romiplostim group and 7 (10.0%) patients in the PBO group. Conclusions: Following the decision in 2011 to stop study drug secondary to increased AML rates at that time and transient blasts increases, final 5-year LTFU HRs (romiplostim vs placebo) for death or progression to AML, respectively, are 1.03 (95% CI: 0.72−1.47) and 1.06 (95% CI: 0.48−2.33). In conclusion, romiplostim reduced bleeding events and platelet transfusions, with no increase in AML incidence or impact on survival. Disclosures Kantarjian: Amgen Inc.: Research Funding.

Abstract Introduction: Venetoclax is a selective, oral inhibitor of BCL2, a key regulator of the intrinsic apoptotic pathway. The dose-escalation phase 1 study of venetoclax in patients with relapsed/refractory non-Hodgkin lymphoma (NHL) enrolled 106 patients from June 2011, and the overall response rate across the entire NHL cohort was 44%. The highest response rate (75%) was seen in the 28 patients with mantle cell lymphoma (MCL) (Davids et al., J Clin Oncol. 2017). Here, we report longer-term outcomes for those patients, now with a median of 27 months (range: 0.2 - 59) follow up. Methods: Venetoclax was administered in dose cohorts ranging from a maximum dose of 300-1200 mg and continued until progressive disease (PD) or unacceptable toxicity; intra-patient dose escalation was allowed. Adverse events (AEs) were assessed by NCI-CTCAE v4.0 and responses were assessed using 2007 Cheson IWG response criteria, utilizing CT scans beginning at week 6. The data cut off for this analysis was June 4th, 2018. Results: For the 28 patients with MCL, the median age was 72 years (range: 35 - 85). They had received a median of 3 (range: 1 - 7) prior treatments; 5 patients received prior PI3K inhibitor (but no prior ibrutinib). The median time from the preceding treatment to start of venetoclax was 13 months (range: 2 - 148). The median dose of venetoclax was 400 mg/day; 25/28 received at least 400mg/day. Median time on study drug was 11 months (range: 0.2 - 59). Three patients have been on therapy for over 4 years. The overall response rate was 75%, with 6 (21%) patients achieving complete remission (CR) and 15 (54%) partial response (PR). The median duration of response was 16 months (95% CI: 4, 30) and median progression free survival was 11 months (95% CI: 5, 21) for all patients (Figure). The 2 year PFS estimate was 30% (95% CI: 14%, 47%) for all patients, 83% (95% CI: 27%, 97%) for patients who achieved CR and 14% (95% CI: 2%, 37%) for patients who achieved PR. One patient who achieved PR proceeded to allogeneic stem cell transplant and remained disease free at the last protocol defined follow-up (24 months after coming off study). Three patients developed progressive disease after receiving venetoclax for more than two years of therapy (time to progression: 31, 33, and 33 months). Two patients with CR continue on study without evidence of progression, currently at 47 and 59 months of venetoclax monotherapy. The most common (≥25% of patients with MCL) all grade treatment emergent AEs were nausea (57%), diarrhea (50%), fatigue (39%), constipation (29%) and upper respiratory infection (25%). The most common (≥10% of patients with MCL) grade 3/4 AEs were neutropenia (14%), anemia (14%), pneumonia (11%), and thrombocytopenia (11%). Biochemical tumor lysis syndrome (TLS), without accompanying clinical features, was reported in one patient considered high risk for TLS. Specific interventions were not required, and the patient continued on study drug. Conclusions: Venetoclax monotherapy leads to durable remission in a meaningful proportion of patients with pretreated MCL. Further studies in MCL are currently investigating potential biomarkers for durable response to venetoclax combination regimens, including a Phase 3 randomized study with ibrutinib (SYMPATICO, NCT03112174).

Background: Current treatment options for red blood cell (RBC) transfusion-dependent (TD) patients with lower risk (LR) myelodysplastic syndromes (MDS) relapsed after or refractory to erythropoiesis-stimulating agents (ESAs) have limited efficacy and durability; new approaches are needed. Imetelstat is a 13-mer lipid-conjugated oligonucleotide that targets the RNA template of human telomerase and is a competitive inhibitor of telomerase enzymatic activity (Asai et al, Cancer Res 2003; Herbert et al, Oncogene 2005). Preclinical, in vivo xenograft models (Dikmen et al, Cancer Res 2005; Hochreiter et al, Clin Cancer Res 2006) and preliminary clinical data from a pilot study conducted at Mayo Clinic (Tefferi et al, Blood Cancer Journal 2016) supported initiation of a study in TD LR MDS patients. A Phase 2 study of imetelstat, IMerge, demonstrated an 8-week RBC transfusion independence (RBC-TI) rate of 42%, 24-week RBC-TI rate of 29%, and 68% erythroid hematologic improvement (HI-E) rate in 38 heavily TD patients (median prior RBC transfusion burden 8 units / 8 weeks over the 16 weeks pre-study period) with LR MDS. Responses were durable with median duration of 8-week RBC-TI of 85.9 weeks by Kaplan Meier estimates (range 8.0-140.9) (Steensma ASH 2018, Fenaux EHA 2019). These Phase 2 results provided further evidence of potential clinical benefit of imetelstat treatment in TD LR MDS, and supported initiation of a Phase 3 trial. Methods: IMerge is two-part, Phase 2/3 study (ClinicalTrials.gov: NCT02598661). The Phase 2 portion of the study described above is closed for enrollment. The Phase 3 portion of the study is open for enrollment of adult patients with International Prognostic Scoring System (IPSS) low or intermediate-1 risk, non-del(5q) MDS, who are TD, are relapsed after or refractory to ESAs, and have not received treatment with lenalidomide or hypomethylating agents. The study is a randomized (2:1) double-blind, placebo-controlled trial to compare efficacy of imetelstat vs. placebo that will enroll approximately 170 patients and will be conducted at approximately 90 centers in North America, Europe, Asia and Middle East. Imetelstat will be administered as 2-hour IV infusion every 4 weeks at 7.5 mg/kg. The primary endpoint of the study is to assess the rate of RBC-TI lasting ≥8 weeks. Secondary endpoints include safety, rate of RBC-TI ≥24 weeks, time to RBC-TI start, RBC-TI duration, rate of HI-E, the amount and relative change in RBC transfusions, rate of CR or PR, overall survival, progression of MDS, pharmacokinetics and effect of treatment on quality of life. Biomarkers relevant to the mechanism of action of imetelstat will be assessed to demonstrate target inhibition and their association with clinical responses. Cytogenetics and mutation analyses will be performed to evaluate the impact of imetelstat on reduction/depletion of malignant clones leading to disease modification.

Abstract BACKGROUND Few Tx options are available for pts with inadequately controlled PV. European LeukemiaNet defined resistance/intolerance was seen in ≈25% pts treated with HU (Alvarez-Larran et al, 2012). In the HU-resistant/intolerant PV pts evaluated in the pivotal RESPONSE study (week [wk] 208), RUX was well tolerated and superior to standard therapy in achieving durable hematocrit (HCT) control, hematologic response, and spleen size and symptom reductions. This Ph 3b ETP study was planned to provide RUX Tx to HU-resistant/intolerant PV pts, who have no alternative standard Tx, and are not eligible for any ongoing clinical studies. Results from wk 24 data cutoff of this study (Devos et al) were presented at ASH 2017. Here, we report consolidated findings from the ETP study at wk 96 data cutoff (Dec 29, 2017 [final database lock]) to further support the use of RUX in this pt population with an unmet medical need. METHODS RUX Tx was initiated at a starting dose of 10 mg bid (could be titrated to a maximum of 25 mg bid). Visits were scheduled every 4 wks until wk 24 and every 12 wks thereafter; final analysis was done when all pts had been followed for 30 days after discontinuation of Tx or completion of Tx per protocol (transitioned to commercial RUX or until Dec 31, 2017, whichever date occurred first). The primary endpoint was to assess the safety of RUX. Secondary endpoints included change in HCT level, change in spleen length, and pt-reported outcomes (change in MPN-SAF TSS score). HCT control at wk 24 was defined by absence of phlebotomy (PBT) eligibility starting at wk 8 and continuing through wk 24, with no more than 1 PBT eligibility occurring after first dose date and prior to wk 8. PBT eligibility was defined by confirmed HCT >45% (at least 3 percentage points higher than HCT at baseline [BL]), or confirmed HCT >48%. Blood count remission at wk 24 was defined by HCT control, and white blood cell count <10 × 109/L, and platelet count ≤400 × 109/L. RESULTS At data cutoff, 161 pts with PV were enrolled (BL characteristics similar to that presented at ASH 2017). End of Tx was reported for all 161 pts: Tx duration completed per protocol (141 pts), adverse event (AE [12 pts]), consent withdrawal (3 pts), pt decision (2 pts), disease progression (2 pts), and death (due to accident [1 pt]). The median exposure was 25.1 wks (range, 0.4-104.7), and median dose intensity of RUX was 20.0 mg/day (range, 6.7-47.7). AEs (regardless of study drug relationship) led to dose adjustment/interruption in 37.9% pts and study drug discontinuation in 8.7% pts. The most common hematologic AEs (rate=number of events per 100 pt-year exposure [pt-year exposure=110.2]; all grades]) included anemia (31.8) and thrombocytosis (10.0), while headache (24.5), diarrhea (14.5), constipation (12.7), and fatigue (12.7) were the most frequent non-hematologic AEs. For all reported grade 3/4 AEs, exposure-adjusted rate was less than 3. Thromboembolic events (all grade; Standardized MedDRA Query) were reported in 3 pts. Disease progression was reported in 4 pts (myelofibrosis=3 pts; acute myeloid leukemia=1 pt). The incidence of other neoplasms (regardless of study drug relationship) was low (leiomyoma, malignant melanoma, marginal zone lymphoma, renal cancer [1 pt each]; squamous cell carcinoma [2 pts]; basal cell carcinoma [3 pts]). Infections (all grades) were reported in 57 pts (grade 3/4 in 5 pts). At wk 24, 73 pts (45.3% [95% CI, 37.5%-53.4%]) achieved HCT control; hematologic remission was seen in 29 pts (18% [95% CI 12.4%-24.8%]). Changes in blood count parameters over time are shown in Fig. 1. In evaluable pts (N=105), use of PBT decreased from BL (39 PBTs between screening and BL) to end of Tx (5 PBTs in 12 wks prior). Best spleen response from BL for each pt by wk 96 is shown in Fig. 2. At least 50% spleen length reduction was seen in 86.7% (78/90) of pts from BL at any time in the study. Overall, 33.8% (46/136) of pts had ≥50% reduction in MPN-SAF TSS from BL at the end of Tx. CONCLUSION The observed safety profile of RUX in the ETP study was consistent with that of the RESPONSE studies. Efficacy results were close to the observed values in the RESPONSE studies. RUX Tx resulted in HCT control, hematologic remission, spleen response, and symptom reduction in this HU-resistant/intolerant pt population in need of a viable Tx option. Safety and efficacy findings from this ETP study support the use of RUX for pts with inadequately controlled PV, an unmet medical need.

Background: Myelofibrosis (MF) is a life-limiting condition with severe morbidity in advanced stages. Patients with MF and severe thrombocytopenia (platelet counts <50,000/mL) have a particularly poor prognosis, with more frequent anemia and leukopenia, higher rates of hemorrhagic and thrombotic complications, and worse overall survival (~15 months) compared to the overall MF population (Scotch AH, et al, Leuk Res. 2017; Masarova L, et al, Eur J Haematol. 2018). Moreover, effective treatment options are limited in this high-risk population as the currently approved JAK inhibitor, ruxolitinib (RUX), is associated with treatment-related thrombocytopenia and often requires dose reductions for patients with platelet counts <100,000/mL, with reduced efficacy compared to patients able to tolerate higher doses. Further, there is no approved dose of RUX for patients with platelet counts <50,000/mL, and NCCN guidelines encourage physicians to consider clinical trials for such patients given the lack of approved therapies. Pacritinib (PAC) is an oral JAK2/IRAK1 inhibitor that has demonstrated clinical activity in MF patients in two prior Phase 3 studies (PERSIST-1, PERSIST-2) as well as a Phase 2 dose-finding study (PAC203), including patients with severe thrombocytopenia. The PACIFICA trial has been designed to evaluate the efficacy and safety of PAC 200 mg BID vs. physician's choice (P/C) therapy in patients with MF and severe thrombocytopenia. Study Design and Methods: PACIFICA is a randomized, controlled Phase 3 trial of PAC vs. P/C in adult patients with primary or secondary MF who are not candidates for stem cell transplant, with DIPSS intermediate- or high-risk disease, ECOG PS ≤2, and platelet counts <50,000/mL, who have had up to 90 days of prior treatment with a JAK2 inhibitor or are JAK2 inhibitor-naïve. Additional exclusion criteria exist for patients with recent cardiac or hemorrhagic events, ejection fraction <50%, QTc >450 msec, or use of medications that increase the risk of hemorrhage or QT prolongation. On the PAC arm, patients receive continuous PAC 200mg BID. On the P/C arm, one of the following agents is selected prior to randomization: low-dose ruxolitinib (no more than 5 mg BID while platelet counts remain <50,000/mL), thalidomide, lenalidomide, corticosteroids, or hydroxyurea. The primary objective is to compare the efficacy of PAC vs. P/C based on the proportion of patients achieving a ≥35% spleen volume response (SVR) at Week 24. Secondary objectives include comparisons of the proportion of patients achieving a ≥50% reduction in total symptom score (TSS) at Week 24, overall survival, and proportion of patients who self-assess as "very much improved" or "much improved" as measured by the patient global impression of change (PGIC). Tertiary endpoints include alternative methods of evaluating SVR improvement, hematologic improvement (transfusion independence and improvement in anemia and thrombocytopenia), improvement in fatigue as measured by the PROMIS - Fatigue - Short form 7a, and changes in mutated allelic burden and gene expression (including correlation with response data). The study will enroll ~180 patients in a 2:1 ratio (PAC to P/C), which will have >80% power to achieve the primary endpoint. Enrollment is anticipated to begin in Q3 2019, as PACIFICA is expected to open as an amendment to the Phase 2 PAC203 study (NCT03165734) in select sites.

Abstract Background: Treatment options for RBC-TD pts with lower-risk MDS without del(5q) who are unresponsive or refractory to ESAs are very limited. In a previous phase 2 study, MDS-002 (CC-5013-MDS-002), LEN was associated with achievement of RBC-transfusion independence (TI) ≥ 56 days in 26% of pts with IPSS Low/Int-1-risk MDS without del(5q) (Raza et al. Blood 2008;111:86-93). This international phase 3 study (CC-5013-MDS-005) compared the efficacy and safety of LEN versus PBO in RBC-TD pts with IPSS Low/Int-1-risk MDS without del(5q) unresponsive or refractory to ESAs. Methods: This multicenter, randomized, double-blind, parallel-group phase 3 study included RBC-TD pts (≥ 2 units packed RBCs [pRBCs]/28 days in the 112 days immediately prior to randomization) with IPSS Low/Int-1-risk MDS without del(5q), who were unresponsive or refractory to ESAs (RBC-TD despite ESA treatment with adequate dose and duration, or serum erythropoietin [EPO] > 500 mU/mL). Pts were randomized 2:1 to oral LEN 10 mg once daily (5 mg for pts with creatinine clearance 40–60 mL/min) or PBO. Pts with RBC-TI ≥ 56 days or erythroid response by Day 168 continued double-blind treatment until erythroid relapse, disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was RBC-TI ≥ 56 days (defined as absence of any RBC transfusions during any 56 consecutive days). Secondary endpoints included time to RBC-TI, duration of RBC-TI, RBC-TI ≥ 168 days, progression to acute myeloid leukemia (AML; WHO criteria), overall survival (OS), and safety. Baseline bone marrow gene expression profiles were evaluated according to the Ebert signature (PloS Med 2008;5:e35) identified as predictive of LEN response. Clinical trial identifier: CT01029262. Results: The intent-to-treat population comprises 239 pts (LEN, n = 160; PBO, n = 79). Baseline characteristics were comparable across treatment groups; median age 71 years (range 43–87), 67.8% male, and median time from diagnosis 2.6 years (range 0.1–29.6). Pts received a median of 3.0 pRBC units/28 days (range 1.5–9.8) and 83.7% received prior therapy, including ESAs (78.7%). Significantly more LEN pts achieved RBC-TI ≥ 56 days versus PBO (26.9% vs 2.5%; P < 0.001; Table). The majority (90%) of pts with RBC-TI ≥ 56 days responded within 16 weeks of treatment. Median duration of RBC-TI ≥ 56 days was 8.2 months (range 5.2–17.8). Baseline factors significantly associated with achievement of RBC-TI ≥ 56 days with LEN were: prior ESAs (vs no ESAs; P = 0.005), serum EPO ≤ 500 mU/mL (vs > 500 mU/mL; P = 0.015), < 4 pRBC units/28 days (vs ≥ 4 pRBC units/28 days; P = 0.036), and female sex (vs male; P = 0.035). RBC-TI ≥ 168 days was achieved in 17.5% and 0% of pts in the LEN and PBO groups, respectively. The incidence of AML progression (per 100 person-years) was 1.91 (95% CI 0.80–4.59) and 2.46 (95% CI 0.79–7.64) for LEN and PBO pts, respectively, with median follow-up 1.6 and 1.3 years. Death on treatment occurred in 2.5% of pts on either LEN or PBO. The follow-up period was insufficient to permit OS comparison between the 2 groups. Myelosuppression was the main adverse event (AE); in the LEN versus PBO groups, respectively, grade 3–4 neutropenia occurred in 61.9% versus 11.4% of pts, and grade 3–4 thrombocytopenia in 35.6% versus 3.8% of pts. Discontinuations due to AEs were reported in 31.9% LEN and 11.4% PBO pts; among the 51 LEN pts who discontinued due to AEs, 14 discontinuations were due to thrombocytopenia and 8 due to neutropenia. In the subset of pts evaluated for the Ebert signature (n = 203), the predictive power of the signature was not confirmed. Conclusions: LEN therapy was associated with a significant achievement of RBC-TI ≥ 56 days in 26.9% of pts with a median duration of RBC-TI of 8.2 months; 90% of pts responded within 16 weeks of treatment. These data were consistent with response rates seen in the MDS-002 trial. The overall safety profile was consistent with the known safety profile of LEN and these data suggest LEN can be safely and effectively used in this patient population. Figure 1 Figure 1.

Abstract Introduction: Quantitative 18fluorodeoxyglucose positron emission tomography (PET)/computed tomography assessment using total metabolic tumor volume (TMTV) and tumor lesion glycolysis (TLG) measurements has been found promising as an objective method to predict survival in diffuse large B-cell lymphoma (DLBCL) patients (pts). However, the methodology for PET-derived metrics is still evolving, and their predictive value is yet to be proven in large-scale, prospective, multicenter studies. We investigated the prognostic value of baseline maximum standardized uptake value (SUVmax), TMTV and TLG for progression-free survival (PFS) in a large pt cohort treated with obinutuzumab (GA101; G) or rituximab (R) combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in the Phase 3 GOYA study (NCT01287741; Vitolo et al. J Clin Oncol 2017). Methods: Pts aged ≥18 years, with previously untreated, CD20-positive DLBCL and an International Prognostic Index (IPI) score ≥2 and low-risk pts with IPI scores of 1 (not due to age alone) or 0 (with bulky disease) were randomized 1:1 to receive 8 x 21-day cycles of G (1000mg intravenous [IV] on Days [D] 1, 8, and 15 of Cycle [C] 1 and D1, C2-8) or R (375mg/m2 IV on D1, C1-8) plus 6 or 8 cycles of CHOP. All pts had a baseline and end of treatment (EOT) PET. PET images were segmented using an automated workflow program in MIM software, applying thresholds of 1.5 x liver background and a minimum volume of 1mL to the whole body PET images. The data were analyzed for the overall population and according to germinal center B-cell-like (GCB), unclassified, and activated B-cell-like (ABC) subtypes of DLBCL. TMTV, TLG, and SUVmax were split into 4 categories/levels according to the following quartiles: Q1, &lt;25%; Q2, 25-50%; Q3, 50-75%; and Q4, 75-100%, which were obtained based on their distribution in the available population. The reported hazard ratios (HRs) refer to stratified log-rank tests comparing Q2, Q3, and Q4 to Q1, adjusted for stratification factors of the study: IPI score (low [0-2], intermediate [3], and high [4-5]) and number of planned CHOP cycles (6 or 8). Results: Of 1418 enrolled pts, 1346 had a baseline PET scan and 1334 had detectable lesions. There was no statistical difference in PFS between the treatment arms (G vs R), thus the entire cohort was analyzed as a whole. Results of the predictive value of baseline TMTV for PFS are presented in quartiles in Figure 1, and results of the predictive value of TLG for PFS are presented in quartiles in Figure 2, for the overall PET intent-to-treat population. After a median follow-up of 29 months TMTV and TLG were highly predictive of PFS when comparing Q4 vs Q1: HR=2.21, 95% CI 1.48-3.29, p&lt;0.0001, and HR=1.91, 95% CI 1.28-2.85, p=0.0005, respectively. TMTV was also predictive of overall survival (OS): HR=2.63, 95% CI 1.55-4.46; p&lt;0.0001. However, SUVmax-based prediction of PFS was not statistically significant (HR=0.84, 95% CI 0.57-1.23, p=0.3782). Three-year PFS for pts in TMTV Q1, 2, 3 and 4 was 86% (95% CI 81-89%), 84% (95% CI 78-88%), 78% (95% CI 72-83%) and 66% (95% CI 59-71%), respectively. TMTV also showed a trend for a better prediction of PFS (Figure 3) and OS in pts with the unclassified and ABC DLBCL subtypes when compared with those with the GCB subtype. Conclusions: This large prospective study confirms baseline TMTV and TLG as predictors of PFS and OS in DLBCL after first-line immunochemotherapy, while SUVmax may not be a predictor. Furthermore, TMTV and TLG appear to be better predictors of survival for pts with the unclassified and ABC subtypes of DLBCL than for those pts with the GCB subtype. Further analyses are underway comparing these results with the predictive value of percentage change from baseline to EOT PET, Deauville score-based analysis of EOT PET, and the various molecular DLBCL subtypes.
