The Impact

Abstract Background Myelofibrosis (MF), polycythemia vera (PV), and essential thrombocythemia (ET) are myeloproliferative neoplasms (MPNs) whose associated disease burden includes a range of debilitating symptoms, thrombosis, hemorrhage, and shortened survival. To enhance patient care, it is important to understand the impact of MPNs in patients' lives; however, little is known regarding how these conditions affect patients' quality of life (QOL), activities of daily living, productivity, and emotional well-being. The US LANDMARK survey (Mesa et al. BMC Cancer 2016) captured data for US patients. Here, we present an interim analysis of results of another MPN LANDMARK survey conducted in the rest of the world. Methodology MPN LANDMARK survey is a cross-sectional survey of MPN patients across 6 countries (Australia, Canada, Germany, Japan, Italy, and UK). Patients completed an online questionnaire to measure MPN related symptoms experienced over the past 12 months and the impact of their condition on their QOL and ability to work. Additional questions related to employment productivity and activity impairment (including absenteeism and loss of productivity over the past 7 days). Patients included in this interim analysis had completed the survey by July 18, 2016, with enrollment continuing in all countries. Results Patients: Overall, 437 patients had completed the survey (98 MF, 121 PV, 218 ET). For MF and PV, the male to female gender split was relatively even (54% male for each), whereas an expected greater proportion of ET patients was female (70%). Patients with MF were significantly older than PV and ET patients (mean ages, 62, 59, and 55 years, respectively) and more had been diagnosed within 2 years of experiencing their symptoms (83% MF, 67% PV, 71% ET). MPN Symptoms (Table): Most patients (94%) experienced MPN-related symptoms in the past 12 months. The most commonly reported symptom among all subtypes was fatigue (69% MF, 62% PV, 73% ET), incidence of other common symptoms varied depending on disease subtype (MF: shortness of breath [38%], bruising [36%], night sweats [35%], early satiety [33%]; PV: night sweats [36%], trouble concentrating [36%], trouble sleeping [34%], dizziness [34%]; ET: trouble sleeping [37%], dizziness [37%], bruising [35%], night sweats [35%]). When asked which symptom patients would most like to have resolved, most patients preferred to have feeling of fatigue/tiredness improved across all disease subtypes (31% MF, 30% PV, 33% ET). Patients experienced an average of 6.4 symptoms at diagnosis but this progressed to an average of 7.6 symptoms since diagnosis after a median time of 6 years. QOL: A majority of patients indicated that they experienced a reduction in QOL due to MPN symptoms (87% MF, 71% PV, 73% ET) with 33% and 26% of MF and ET patients expressing that their condition has caused emotional hardship, and one-third of patients with PV reporting that they have felt worried or anxious about their disease (39%). MPN Impact on Activity/Employment: Patients reported a high impact on their ability to work, 12% reported voluntarily leaving their job, 10% had taken early retirement, 10% had moved onto disability living allowance, 8% moved to a lower paid job, and 2% experienced involuntary loss of work (Table). Of the patients who were in full-time or part-time employment at the time of the survey (MF [n=17]), PV [n=41], ET [n=98]), approximately, 40% had been absent from work within the past 7 days; this was the highest in MF patients (41% MF, 38% PV, 33% ET). On an average, over the past 7 days, MF patients had missed 3.1 hours from work, PV patients 2.3 hours and ET patients 2 hours. Across all subgroups, a substantial proportion of patients reported impairment in work (mean: 34% MF, 33% PV, 31% ET) and overall activity (mean: 46% MF, 42% PV, 39% ET). Conclusions This interim analysis from the MPN LANDMARK survey indicates that MPN patients experience a high burden of disease, including a high prevalence of symptoms, an increase in the number of symptoms from diagnosis and reduction of their emotional well-being, QOL, and ability to work. These results are consistent with those from the previous US LANDMARK survey with the addition of novel data on how MPNs impact work. When treating MPN patients, care should be taken in trying to manage a patient's disease burden, so as to minimize the impact on a patient's daily life. Further results from additional survey responses will be presented at the congress.

The Impact

Abstract Introduction: Myeloproliferative neoplasms (MPN) are a heterogeneous group of chronic myeloid malignancies resulting from the combination of a driver mutated gene (JAK2, MPL or CALR) and a variety of acquired additional somatic mutations. Although next-generation sequencing (NGS) has identified high molecular risk mutations associated with adverse prognosis (Vannucchi et al., Leukemia, 2013 , Guglielmelli et al., Leukemia, 2014 ), the clonal evolution of these mutations remains poorly described. Chronic exposure to cytoreductive treatment, especially genotoxic drugs such as hydroxyurea (HU), could impact clonal evolution. A previous study suggested that Interferon-α (IFN) could limit the accumulation of cytogenetic abnormalities compared to HU (Mondello et al., Blood, 2018). The objective of our study was to describe the long-term evolution of the mutational landscape in the era of NGS in a large cohort of MPN patients. Methods: A total of 1538 consecutive patients were diagnosed with MPN according to WHO criteria and followed in our hospital between January 2011 and January 2021. This study included 1039 of them in whom a NGS molecular analysis targeting 36 myeloid genes with a sensitivity of 1% was performed at diagnosis and/or during follow-up. Patients with only one NGS (n=588), AML/MDS transformation at either the first (n=3) or the second NGS (n=2) were excluded from the analysis. Serial NGS data obtained in chronic MPN phase were thus analyzed for 446 patients. Clinical and biological characteristics at time of diagnosis and follow-up were collected from medical charts and electronic medical records. Mutation rates per year were calculated for each gene as the difference in the number of mutations between first and last NGS divided by the time interval (in years) between both NGS. Results : Median age at MPN diagnosis in our whole cohort was 51 years [IQR 41-60]. Our cohort included 167 (37%), 205 (46%) and 64 (14%) patients with Polycythemia Vera (PV), Essential thrombocythemia (ET) and primary myelofibrosis (MF) respectively. 279 patients (63%) had at least one additional mutation at first NGS, and respectively 27 (6%) and 104 (23%) patients had TP53 and high molecular risk mutations. Median interval between MPN diagnosis and the first NGS was 6.5 years [IQR 1.7-13] while median time between the first and the last NGS was 2.5 years [IQR 1.6-4, range 0.3-14.3]. Overall, 178 patients (39.9%) acquired an additional mutation at last NGS evaluation, most frequently involving TET2, DNMT3A, ASXL1, TP53 and NFE2 genes . To study the impact of chronic MPN therapy on clonal evolution, we focused on patients who electively received HU (n=112) or IFN (n=92) as a monotherapy, or did not receive any cytoreductive treatment (n=119) between the first and the last NGS. The remaining patients received ruxolitinib (n=44), anagrelide (n=10), vercyte (n=7) or polytherapy (n=62). At last follow-up, 74 patients receiving IFN (80.4%) and 65 (58%) treated with HU had a complete hematological response. When combining all additional mutations, the global mutation rate per year did not significantly differ between treatment groups. When analyzing individual genes, TP53 mutation rate was higher in patients treated with HU compared to the patients receiving IFN (p=0.014) or not treated (p=0.008) (Figure). MDS/AML evolution occurred in 4 patients (3.6%) treated with HU, 2 (1.7%) without cytoreductive therapy versus none of the 92 patients treated with IFN (ns). In the whole cohort, MDS/AML evolution was significantly increased in patients harboring TP53 mutations (p= 0.004). In contrast, DNMT3A mutation rate was significantly increased in patients receiving IFN compared to patients treated with HU (p=0.045) (Figure). The latest result is in line with previous observations showing that loss of DNMT3A could confer resistance to IFN in a JAK2-V617F mouse model (Stetka et al., Blood, 2020). Conclusion: Our results highlight the impact of chronic cytoreductive therapy on clonal evolution shaping in MPN. IFN limits the emergence of TP53 mutated clones compared to HU, thus potentially reducing the risk of leukemogenesis. Emergence of DNMT3A mutated clones under IFN therapy requires further exploration and could potentially play a role in therapeutic resistance. This study on a large clinically and biologically annotated cohort illustrates how serial NGS analysis may guide therapeutic options for MPN patients. Figure 1 Figure 1.

The Impact

Background: The introduction of the JAK1/2 inhibitor Ruxolitinib has resulted in significant benefits for patients with Myelofibrosis (MF) and Polycythemia Vera, including reduction of splenomegaly and improvement in symptom burden. However, Ruxolitinib has limited ability to alter the natural history and biology of disease in myeloproliferative neoplasms (MPNs). More importantly, patients often lose response to ruxolitinib or suffer disease progression despite therapy with ruxolitinib. These observations have prompted efforts to introduce novel therapeutic approaches and devise novel combinatorial treatment strategies to improve the outcomes of patients with MPNs. CD123 (interleukin-3 receptor-a; IL-3R-a) has been identified as a therapeutic target in several myeloid malignancies. CD123 is expressed in a variety of myeloid malignancies, including AML, myelodysplastic syndrome (MDS) and CMML. Further, Tagraxofusp (ELZONRIS®, SL-401), a targeted therapy directed to CD123 comprised of recombinant IL-3 fused to a truncated diphtheria toxin payload, was recently FDA approved for the treatment of blastic plasmacytoid dendritic cell neoplasm (BPDCN). In an ongoing Phase 1/2 trial, Tagraxofusp has demonstrated single agent clinical activity, with a predictable and manageable safety profile, in patients with relapsed/refractory MF. Thus, Tagraxofusp appears to have activity in MF. However, the utility of Tagraxofusp in more advanced forms of MPN (such as accelerated phase MPN), as well as the utility of combination Ruxolitinib and Tagraxofusp, have not been evaluated to date. To address these questions, we first evaluated CD123 expression using flow cytometry analysis of peripheral blood samples from patients with MF with progression to accelerated-phase (>10%) or blast-phase (>20%) disease. CD123 expression was generally noted to be higher than that observed in normal control samples, by mean florescence intensity (Figure 1A). We next sought to determine the effect of treatment with Tagraxofusp alone and in combination with Ruxolitinib in leukemia cell lines and primary patient samples. We performed cell viability assays using the JAK2V617F mutant cell line UKE1. We first determined the IC50 of Tagraxofusp in UKE1 cells (range 2.95-3.57nM). Using this data, we then tested the impact of the addition of Tagraxofusp to Ruxolitinib on UKE1 cell viability using a fixed concentration of Tagraxofusp (5nM). The IC50 of range of single agent Ruxolitinib was 44.42-70.93nM. However, the addition of Tagraxofusp to Ruxolitinib resulted in a decrease of the IC50 range to 11.72-21.6nM, indicating an effect of combination therapy (Figure 1B). We then determined the impact of Tagraxofusp both alone and in combination with Ruxolitinib using primary patient MPN peripheral blood mononuclear cells in methylcellulose. Patient characteristics are described in Table 1. In most samples, CD123 expression was confirmed. In all samples studied, Tagraxofusp was able to significantly reduce colony formation when compared to vehicle, at a dose range of 2.5nM to 20nM. Notably, this includes two samples (151, 455) from patients with accelerated-phase disease. As well, Tagraxofusp demonstrated activity across genotypes, including in cases with TP53 and ASXL1 mutations. A reduction in colony formation in samples treated with combination Ruxolitinib and Tagraxofusp beyond that observed with either agent alone was observed in several cases (Figure 1C). Conclusions: Current therapeutic options for patients with MF beyond Ruxolitinib are limited. This is particularly the case for patients with progression to accelerated and blast-phase MPN. Here, we demonstrate that CD123 expression is evident in many such cases. Further, therapeutic targeting of CD123 using Tagraxofusp either alone or in combination with Ruxolitinib has activity in primary patient samples, including those in accelerated-phase and with high molecular risk profiles. These data thus support further testing of Tagraxofusp in MPNs, and in advanced MPNs in particular.

Abstract Background: The impact of ITP on patient (pt) QoL is multidimensional, broadly encompassing daily activities, emotional health, and work life. Health-related QoL has been shown to be substantially reduced in ITP pts relative to healthy controls, yet the full impact of ITP on affected pts is not well-defined. Aims: I-WISh studied the burden of ITP and its impact on QoL using a global pt and physician (MD) sampling frame. This analysis reports the impact of ITP on QoL, emotional health, and work productivity, and evaluates similarities and differences between pt and MD viewpoints. Methods : I-WISh is a cross-sectional survey of ITP pts, recruited via MDs and pt support groups, and MDs recruited via local fieldwork agencies. Participants (pts and MDs) completed a 30-minute online survey that included demographics and the impact of ITP on QoL, emotional health, work productivity, and need for caregivers. A steering committee of expert MD and pt advocacy leads specializing in ITP designed and endorsed survey materials. Results: 1491 pts from 12 countries completed the survey; 65% were female, mean (SD) age was 47 (16) years. 472 MDs from 13 countries completed the survey; 56% were university or teaching hospital based, with a mean (SD) ITP pt caseload of 34 (50) and a mean (SD) of 18 (36) newly-diagnosed pts in the past year. Overall, 84% (n=1258/1489) of pts reported that ITP reduced their energy levels, 77% (n=1149/1489) said ITP reduced their capacity to exercise, 75% (n=1116/1489) said ITP limited their ability to perform daily tasks, and 70% (n=1035/1485) said ITP impaired their social life. The proportion of pts reporting an impact of ITP on their QoL increased with symptom burden (Figure A); 98% of pts (n=298/303) with the greatest symptom burden reported an impact on energy levels and >90% reported an impact of ITP for 6/10 questions. MDs perceived potential bleeding as having the greatest impact on pt QoL (scored ≥5 on a 7-point Likert scale, where 7=great deal), with 88%, 73%, and 69% perceiving concerns of increased bleeding risk during sport, travel, and sex, respectively, as areas in which pt QoL could be affected. Fewer MDs than pts felt that ITP would greatly impact daily activities (52% vs 75%) or family and social life (45% vs 70%). 82% of MDs indicated they either do or would use a pt QoL tool at least every 6 months to monitor pts. Almost half (49%; n=731) of all pts stated ITP had a high impact on their emotional well-being (score ≥5 on 7-point Likert scale, where 7=great deal), with 63% (n=944) worried their condition would worsen. More pts with very high symptom burden reported high emotional impact (75%; n=227/303), with 85% (n=259/303) worrying about their condition worsening. MDs gave similar results to pts for emotional impact and considered anxiety about platelet counts the primary cause (85%). Nearly half of pts who worked (43%; n=383/894) reported that ITP affects their work productivity (score ≥4 on a 10-point scale, where 10=completely prevented from working), with 24% (n=212/889) having missed ≥6 hours' work in the week prior to survey completion. 48% (n=715/1491) of all pts had either reduced or seriously considered reducing their hours at work, and 21% (n=306/1491) had considered terminating their employment because of ITP (Figure B). Despite this, 62% (n=554/888) work >30 hours/week. Pts with very high symptom burden (n=303) reported greater impact on their work, with 69% either having reduced or seriously considering reducing their hours and 43% having considered terminating employment. Over half of pts (52%) reported needing care assistance, with their spouse being the main caregiver (59%; n=461/775), requiring an average of 16.3 hours of support in a week. Caregivers provided companionship (69%; n=534/775), helped with household chores (55%; n=429/775), and aided transportation (50%; n=386/775). Summary/conclusions: I-WISh demonstrates that most ITP pts experience substantially impaired QoL, with daily activities, social interactions, emotional well-being, and working lives all affected. Pts frequently report severe fatigue and pts with high ITP symptom burden were particularly affected, with nearly all pts reporting substantially reduced energy levels. Pts also worried about their condition worsening and had reduced work capacity. These results highlight the need for MDs to consider the impact of ITP disease burden on all aspects of individual pts' lives during management of ITP.

Abstract Background Tyrosine kinase inhibitors (TKIs) are the standard of care for pts with CP-CML. Current recommendation is to continue TKI therapy indefinitely but previous studies indicate that pts with deep and sustained molecular responses (MRs) on imatinib (IM) may achieve long-lasting TFR. Nilotinib (NIL) at 300mg BID induces higher rates of deep MRs compared to IM and high dose NIL (400mg BID) enables a substantial proportion of pts who do not obtain MR4 (BCR-ABL1IS £ 0.01%) or MR4.5 (BCR-ABL1IS £ 0.0032%) with IM to reach such deep MRs levels, potentially compatible with TFR. However, optimal duration of treatment with NIL to ensure the highest rate of TFR after treatment discontinuation is unknown. Objective ENESTPath was designed to assess the optimal duration of NIL therapy that is necessary to achieve and maintain TFR upon treatment discontinuation in pts pretreated with IM. Methods ENESTPath is a randomized, phase III study enrolling CP-CML pts who after at least 2 years (yrs) of IM therapy achieved a complete cytogenetic response (CCyR), but not yet a MR4. After enrollment, pts were assigned to receive NIL at 300 mg BID for 2 yrs or 3 yrs (Arm 1 and Arm 2, respectively). Patients who will obtain a stable MR4 or better for at least 12 months (mo) will enter the TFR phase. Primary endpoint is to evaluate the proportion of pts in both arms who will remain in TFR for ≥1 yr after NIL discontinuation. Results 620 pts were enrolled in the study between May-2013 & Apr-2015. In this interim analysis, the first 300 pts (mean age 50.8 yrs; 63.7% male) enrolled and treated with NIL for ≥1 yr have been included. Baseline characteristics are detailed in the Table. By 12 mo of NIL treatment, cumulative incidences of newly acquired MR4 and MR4.5 were 57.4% and 30.5%, respectively. Further analysis of MR4 achievement showed that pts with a major molecular response (MMR: BCR-ABL1IS >0.01% - ≤0.1%) at baseline had a higher probability to achieve a MR4 than those lacking MMR at baseline, with a cumulative incidence of MR4 by 12 months of 64.8% and 30.8%, respectively (Figure). Adverse events (AEs) were mostly of grade 1-2, manageable with supportive care or NIL dose interruption/reduction and included pruritus (19%), headache (9%), skin rash (9%), upper abdominal pain (8%) and constipation (7%). Grade 3-4 hematologic AEs were uncommon. The incidence of grade 3-4 laboratory abnormalities was low: lipase increase, hyperglycemia, ALT and AST increase, hyperbilirubinemia and hypercholesterolemia reported in 3.7%, 1.3%, 1%, 0.7%, 0.3%, 0.3% pts, respectively. Grade 3-4 ischemic cardiovascular events were experienced by 5% of pts including peripheral artery occlusive disease (1.7%) and coronary artery disease (3.7%) (1 pt experienced both AEs). Sub-analyses aiming to evaluate the impact of baseline SCOREa CV risk factor on the onset of arterial ischemic events are currently ongoing. Results on 168 pts showed grade 3-4 ischemic CV events in 19% of pts who were at very high or high risk (n = 47) compared to 1.7% of in pts with moderate or low risk (n = 121). During the first 12 mo, 48 (16%) pts discontinued NIL therapy: 32 discontinued due to AEs/laboratory abnormalities, 12 withdrew consent, 4 due to other reasons (protocol deviation, pregnancy and non-compliance). No patients left the study due to progression to AP/BP. Till date there were no on-treatment deaths. Conclusions This interim analysis shows that a switch to NIL at lower doses than in prior studies (300mg BID instead of 400mg BID) induces high rates of MR4 and MR4.5 in pts without such MR levels on IM. The safety profile of NIL at 300mg BID is consistent with that described in other prospective studies.Thus a switch to NIL for pts not achieving a deep MR during IM therapy is predicted to substantially increase the probability of achieving TFR requirements. A longer follow-up is necessary to assess what may be the best duration of NIL prior to treatment discontinuation. aRisk factors evaluated by applying the SCORE chart proposed by the European Society of Cardiology Table 1.

Abstract Background: The Philadelphia chromosome negative myeloproliferative neoplasms (MPNs), including essential thrombocythemia (ET), polycythemia vera (PV) and myelofibrosis (MF) all have a time dependent risk of progression to either an advanced myelofibrotic state (post ET/PV MF) and/or to acute myeloid leukemia. The impact of disease duration upon the MPN symptom burden is not well understood, nor are the precise mechanisms of disease progression. We sought to better understand the impact of disease duration on MPN symptom burden. Methods: Symptom burden data was collected utilizing the Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) amongst MPN patients, collected at the time of an office visit in an international cohort of MPN patients as previously described (Scherber et. al.). Symptom burden assessment was a previously validated 27-item symptom burden questionnaire scored on a 0-10 scale (0= as good as it can be, 10 = as bad as it could be). The patient or provider was asked to report the time since MPN diagnosis. MPN duration was determined to be early if the diagnosis was established between 0 to 5 years ago, intermediate if the diagnosis was established between 6 to 10 years ago, and late if the diagnosis was established 11 years ago or more. Anemia was defined as a red blood cell count less than 10 g/dL, leukopenia was defined as a white blood cell count was below 4 x 109, and thrombocytopenia if the platelet count was below 150 x109. Statistical significance was calculated using ANOVA f-test and chi squared. Results: Patient demographics and disease burden: A total of 1443 patients responded to the survey, including 592 (41%) ET, 549 (38%) PV, and 302 (21%) MF patients, including 181 (60%) primary MF, 67 (22%) post-ET MF, and 54 (18%) post-PV MF. Among MF patients, mean duration of MPN diagnosis was 9 years, and mean duration MF diagnosis was 4.7 years. Among respondents, 757 fit criteria for early disease duration, 353 fit criteria for intermediate disease duration, and 333 fit criteria for late disease duration. Respondent mean age was 62 years and approximately half of respondents were female (55%). Patients with longer diagnosis duration tended to be older (p=0.009) and were most likely to have anemia (0.02), leukopenia (p=0.01), or thrombocytopenia (p=0.03). These individuals were also most likely to have a history of hemorrhage (p=0.007) or require red blood cell transfusions (p<0.001). Combined cohort symptom burden: On average among the combined cohort of ET, PV and MF patients, symptoms tended to worsen with time with this effect being significant for symptom items of fatigue (BFI, p<0.04), concentration (p=0.007), insomnia (p=0.02), sexual difficulties (p=0.002), cough (p=0.03), night sweats (p=0.002), and pruritus (p=0.02). Symptoms of early satiety (p=0.004), concentration difficulties (p=0.01), insomnia (p=0.03), sexual difficulties (p=0.02), cough (p=0.01), and night sweats (p=<0.001) had significantly higher prevalence in those with longer disease duration. Similarly, the total calculated MPN-10 score (p=0.008) and quality of life assessment (0.03) demonstrated worsened outcomes with time (Table 1). No significant differences in symptoms for the combined cohort were observed among individuals diagnosed 0 to 1 years ago compared to those with a diagnosis established between 2 and 5 years ago. Symptom burden in MPN subtypes. When evaluating specific MPN types, patients with essential thrombocythemia experienced significantly greater sexual difficulties over time (p=0.03). The severity (p=0.01) and incidence (p=0.03) of pruritus and incidence of night sweats (p<0.001) were significantly increased over time for individuals with PV. For those with MF, the severity (p= 0.01) and incidence (p=0.009) of cough also significantly increased with longer diagnosis duration. Discussion Overall, significant worsening in symptom burden can be recognized over time for individuals diagnosed with MPNs. Diagnosis may not necessarily correlate with disease duration as the timing of diagnosis may be delayed from onset of disease. Given the intent of this abstract to evaluate changes with disease duration, we did not investigate correlations between symptom burden and cytopenias. We do know that risk factors for survival in the MPNs include older age and thrombosis, however, disease duration should be investigated as an alternative marker of burden in future survival studies.

INTRODUCTION: PNH, a rare, chronic, life-threatening disease, is characterized by hemolytic anemia due to uncontrolled activity of the complement alternative pathway (AP), bone marrow failure, and thrombosis. Inhibition of C5 by intravenously administered eculizumab and ravulizumab reduces intravascular hemolysis, but PNH red blood cells (RBCs) become opsonized and susceptible to extravascular hemolysis (Risitano et al, Blood 2009). Only approximately half of PNH patients become transfusion independent with eculizumab treatment (Hillmen et al, NEJM 2006). BCX9930 is a potent, selective, orally administered inhibitor of complement factor D. Inhibition of factor D may prevent both intravascular and extravascular hemolysis in PNH. In healthy subjects, BCX9930 showed linear pharmacokinetics and dose-related AP suppression, and was safe and generally well-tolerated over a wide dose range. Here we describe safety and laboratory data establishing proof-of-concept for BCX9930 monotherapy in PNH patients in Study BCX9930-101 (NCT04330534). METHODS: Ongoing Study BCX9930-101 includes an open-label, dose-ranging evaluation of BCX9930 in PNH subjects who may either be naïve to C5 inhibitors (and receive BCX9930 as monotherapy) or have an incomplete treatment response to eculizumab or ravulizumab (with BCX9930 added to existing treatment). Up to 4 sequential cohorts each use a forced titration design for the first 28 days (Figure 1). Subjects enrolled in South Africa can participate in an individualized 48-week extension if they derive benefit at Day 28. Clinical benefit from BCX9930 is evaluated using laboratory monitoring and symptom assessment. Safety and tolerability are evaluated via clinical and laboratory monitoring, causality of adverse events is assessed by investigators, and the study is overseen by an independent Data Monitoring Committee. Data from Cohort 1 through 28 days is reported; data from the extension and subsequent cohorts will be subsequently summarized as available. RESULTS: To date, four C5 inhibitor naïve PNH subjects in South Africa have enrolled in Cohort 1. These subjects had PNH for a median of 4.5 years; 2 subjects had a history of transfusions in the past year; 1 subject each had a history of aplastic anemia or major thrombosis. Pre-treatment lactate dehydrogenase (LDH), total bilirubin, hemoglobin (Hb), reticulocyte count, and RBC PNH Type III clone size ranged from 3.7-11.1 × ULN, 0.61-3.3 mg/dL, 6.1-11.6 g/dL, 0.13-0.29 × 106/µL, and 41.4%-88.6% respectively. Treatment over 28 days with 50 mg twice daily (BID; Days 1-14) and 100 mg BID (Days 15-28) of BCX9930 produced dose-dependent, clinically meaningful improvements across hemolysis biomarkers (Figure 2). Decreases were observed in LDH (4/4), reticulocytes (4/4), and total bilirubin (2/2 subjects with elevated pre-treatment values). Increases were observed in Hb (3/4) and PNH RBC clone size (4/4). One subject showed an initial response to BCX9930 50 mg BID, followed by worsening indicators of hemolysis temporally associated with an upper respiratory tract infection (URTI; onset on Day 7). With an increase in dose to 100 mg BID and resolution of the URTI, LDH and reticulocytes fell and Hb rose. All four subjects reported one or more PNH-associated symptoms, including hemoglobinuria, jaundice, fatigue, erectile dysfunction, headache and abdominal pain, prior to enrollment. With the exception of one subject with persistent hemoglobinuria, all symptoms resolved by Day 28 on BCX9930. Three subjects experienced moderate headache that resolved in &lt; 3 days after initiating BCX9930. One subject developed a rash during treatment with amoxicillin for an URTI; the rash resolved while continuing BCX9930 dosing. One subject on concomitant chronic corticosteroids and azathioprine had an unrelated fatal serious adverse event of disseminated varicella during the study extension. Based on review of safety data, Cohort 2 opened at doses of 200 mg BID and 400 mg BID and, in the 3 subjects who continued into the extension, the dose was titrated to ≥ 200 mg BID. CONCLUSIONS: Oral BCX9930 elicited rapid changes in laboratory parameters indicative of reduced hemolysis and clinical benefit and was safe and generally well-tolerated over a 28-day dosing interval. These interim results establish proof of concept for monotherapy with BCX9930 in the treatment of C5-inhibitor naïve PNH patients and support evaluation of higher doses.

Abstract Abstract 782 Introduction: Current evidence indicates that acquired genetic instability in chronic myeloid leukemia (CML) as a consequence of the t(9;22)(q34;q11) and the resulting BCR-ABL fusion causes the continuous acquisition of additional chromosomal aberrations (ACA) and mutations and thereby progression to accelerated phase and blast crisis (BC). Around 10 –12% of patients in chronic phase (CP) CML have ACA already at diagnosis. During the course of the disease this number rises to 80% in BC. Acquisition of ACA during treatment is considered as a poor prognostic indicator, whereas the impact of ACA at diagnosis is controversial. Patients and methods: Clinical and cytogenetic data of 1151 out of 1311 patients with Philadelphia and BCR-ABL positive CP CML randomized until 2009 to the German CML-Study IV were investigated in a prospective study. There were 459 females (40%) and 692 males (60%). Median age was 53 years (range, 16–88). All patients were treated with imatinib alone or in combination with interferon alpha or araC. The impact of ACA at diagnosis on time to complete cytogenetic and major molecular remission (CCR, MMR) and progression-free and overall survival (PFS, OS) was investigated. Written informed consent was obtained from all patients prior to entering the study. Results: At diagnosis 1003/1151 patients (87%) had the standard t(9;22)(q34;q11) only and 69 patients (6.0%) had a variant t(v;22). In 60 of 69 patients with t(v;22), only one further chromosome was involved in the translocation, in 7 patients two, and in 2 patients three further chromosomes were involved. Seventy-nine patients (6.9%) had ACA. Of these, 38 patients (3.3%) lacked the Y chromosome (-Y) and 41 patients (3.6%) had ACA except -Y. Sixteen of the 41 patients had major-route ACA (+8, i(17)(q10), +der(22)t(9;22)(q34;q11), ider(22)(q10)t(9;22)(q34;q11)) and 25 minor-route ACA [e.g. t(3;12), t(4;6), t(2;16), t(1;21)]. In patients with major-route ACA, trisomy 8 was the most frequent additional alteration (n=9). +der(22)t(9;22)(q34;q11) was observed in six patients, isochromosome (17)(q10) in five patients and ider(22)(q10)t(9;22)(q34;11) in three patients. After a median observation time of 5.3 years for patients with t(9;22), t(v;22), -Y, minor- and major-route ACA median times to CCR were 1.01, 0.95, 0.98, 1.49 and 1.51 years, to MMR 1.40, 1.58, 1.65, 2.49 and > 7 years, 5-year PFS 90%, 81%, 88%, 96% and 50% and 5-year OS 92%, 87%, 91%, 96% and 53%, respectively. In patients with major-route ACA times to CCR and MMR were longer. PFS and OS were shorter (p<0.001) than with standard t(9;22)(q34;q11). Loss of Y chromosome had no influence on time to CCR or MMR, PFS and OS. Conclusion: We conclude that the prognostic impact of additional cytogenetic findings at diagnosis of CML is heterogeneous and consideration of their types may be important. Major-route ACA identify a small group of patients with significantly poorer prognosis as compared to all other patients requiring early and more intensive intervention such as stem cell transplantation.

Abstract Abstract 4591 Introduction: Clinicians and investigators appreciate the value of measuring HRQOL for monitoring CLL and the impact of treatments, and commonly use ECOG performance status (PS) and clinician-reported patient fatigue as surrogates for HRQOL in clinical practice. However, limited data exist on the relationships between PS, fatigue, and HRQOL in CLL patients (pts) undergoing treatment in clinical practices. We examined the associations between these measures and 3 psychometrically validated, patient-reported, HRQOL instruments: the Brief Fatigue Inventory (BFI), EQ-5D, and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu). Methods: Data were collected as part of Connect CLL®, a prospective observational registry initiated in March 2010 involving US practices. Data on pt demographics and clinical characteristics were provided by clinicians. HRQOL was self-reported by pts at enrollment using the BFI, EQ-5D, and FACT-Leu. Mean BFI, EQ-5D and FACT-Leu scores were analyzed by ECOG PS and clinician-reported fatigue. Differences in HRQOL scores between sub-cohorts were assessed by ANOVA. Results: HRQOL data were reported by 604 pts enrolled from 10 academic, 148 community, and 3 government centers. Pts were predominantly male (62%) and white (90%); mean age was 70 (standard deviation 11) years. BFI data (scale: 0 [no fatigue] - 10 [worst fatigue]) indicated that on average pts report that global fatigue, fatigue severity and fatigue-related interference worsen by ECOG severity (Table 1) and are statistically associated with clinician-reported fatigue (Table 2). Mean EQ-5D overall HRQOL as measured by a Visual Analogue Scale (VAS) from 0 (worst) to 100 (best) worsens by ECOG severity and is significantly worse in pts with fatigue. Mean EQ-5D domain scores (scale: 1 [no problem], 2 [some problems], 3 [incapacity]) indicated that pain/discomfort, mobility and usual activities increase in severity as ECOG worsens and in pts with fatigue. FACT-Leu domains except social/family were statistically worse with worse ECOG PS and in pts with fatigue. Conclusions: Initial results from Connect CLL® indicate that HRQOL worsens with worsening ECOG PS, especially in physical / functioning domains, pain/discomfort, and mobility, and worsens across multiple domains among pts whose physicians reported fatigue. Future analyses should be conducted on how HRQOL, PS and fatigue may change over time with changes in CLL, and how they are influenced by therapies. These results may serve as baseline reference.

Abstract Background Patients with myocardial iron overload require effective cardiac iron removal to minimize the risk of cardiac complications. The 3 year EPIC cardiac sub-study showed that the oral iron chelator, deferasirox (DFX), effectively reduced cardiac iron overload. Previous reports demonstrate that cardiac iron removal is slow and suggest that liver iron concentration (LIC) may affect cardiac iron removal rate by chelators (Pennell et al., 2012; Blood). The objective of these analyses was to evaluate the impact of the severity of the liver iron overload on the change in myocardial T2* (mT2*) for patients receiving up to 3 years of DFX treatment in the EPIC sub-study. Methods Inclusion and exclusion criteria have been described previously (Pennell et al., 2012; Haematologica). Patients were categorized into LIC ≤15 and >15 mg Fe/g dry weight (hereafter mg/g) at baseline (BL) and by LIC <7, 7–≤15 and >15 mg/g at 12, 24, and 36 months to assess the impact of BL LIC and changes in LIC overtime on mT2*, respectively. During study, LIC and mT2* were measured every 6 months. Efficacy was assessed in per-protocol population that entered third year extension. Here, mT2* is presented as the geometric mean (Gmean) ± coefficient of variation (CV) unless otherwise specified. Statistical significance was established at α-level of 0.05 using a 2-sided paired t-test for within group comparisons and ANOVA for multiple group comparisons. All p-values were of exploratory nature for this post-hoc analysis. Results Of the 71 patients, who continued into study year 3, 68 patients considered evaluable were included in this analysis (per protocol population); 59 patients had LIC values available at end of study (EOS). Mean age was 20.5 ±7.35 years and 61.8 % of patients were female. Mean actual dose of DFX (mg/kg/day) was 32.1 ±5.5 and 35.1 ±4.9 in patients with BL LIC ≤15 and >15 mg/g, respectively. At EOS, mean actual doses were 32.9 ±5.4 (LIC <7 mg/g), 38.0 ±3.4 (LIC 7–≤15 mg/g), and 37.6 ±3.1 (LIC >15 mg/g). Overall, patients had high BL LIC (Mean, 29.0 ±10.0 mg/g); 61 patients had LIC >15 (30.8 ±8.8) mg/g, only 7 patients had LIC ≤15 (12.7 ±1.1) mg/g, and no patients had LIC <7 mg/g. After 36 months, a significant mean decrease from BL in LIC of -7.6 ±4.6 mg/g (p = 0.0049) and -16.8 ±14.0 mg/g (p <0.001) was observed in patients with LIC ≤15 and >15 mg/g, respectively. Notably, 51.9% of patients with BL LIC >15 mg/g achieved EOS LIC <7 mg/g. Overall, mean mT2* was 12.8 ±4.6 ms. The impact of BL LIC on mT2* and LIC response was as follows: in patients with LIC ≤15 mg/g (Mean BL mT2*, 14.2 ±3.6 ms) and >15 mg/g (BL mT2*, 12.7 ±4.7 ms), mT2* increased by 52% (Mean abs. change, 7.5 ±4.1 ms, p=0.0016) and 46% (7.3 ±7.3 ms, p<0.001), respectively. Patients with BL LIC ≤15 normalized mT2* in 24 months (Mean, 20.0 ±6.0 ms) versus 36 months for patients with BL LIC >15 mg/g, (20.1 ±10.6 ms) displaying a lag of nearly 12 months. The relation between post-BL LIC on mT2* response at 12, 24 and 36 months is shown in the figure. At 12 months, there was no significant difference in mT2* that had occurred in patients with LIC <7 mg/g (24% increase; mean abs. change, 3.5 ±2.3 ms), LIC 7–≤15 mg/g (19% increase; 3.4 ±5.2 ms) and those with LIC >15 mg/g (13% increase; 1.9 ±3.2 ms). However, at 24 months, there was a statistically significant difference amongst the 3 subgroups in percent increase in the mT2* that had occurred; patients with LIC <7, LIC 7-≤15 and LIC >15 mg/g had 54% (Mean abs. change, 8.3 ±7.3 ms), 33% (5.2 ±5.2 ms) and 10% (2.1 ±4.3 ms) increase (p <0.001), respectively. Similarly, at 36 months, the mT2* had increased by 71% (Mean abs. change, 10.3 ±6.6 ms) in the LIC <7 mg/g group; a 31% increase (5.3 ±5.0 ms) had occurred in the LIC 7– ≤15 mg/g group; and an 18% (3.3 ±6.0 ms) increase (p <0.001) had occurred in the LIC >15mg/g group. At all-time points, in patients who achieved an LIC <7 mg/g, a statistically significant increase in T2* from BL had occurred. Discussion Overall, DFX treatment resulted in a significant decrease in LIC and improved mT2*. A greater difference in mT2* improvement was shown to have occurred in patients who achieved lower end-of-year LIC after treated with DFX. This divergence was progressive with time, being maximal at 36 months. Thus, a therapeutic response in LIC with DFX is associated with a greater likelihood of improving mT2*. This may assist in monitoring liver and cardiac response to DFX. Prospective evaluation of this relationship is indicated.

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.
