Symptom Severity and Clinical Variables of Polycythemia Vera Patients with Splenomegaly, Phlebotomy Requirements and/or Hydroxyurea Use: a Retrospective Evaluation of 1334 Patients

Abstract Background Polycythemia vera (PV) is a clonal myeloproliferative disorder characterized by erythrocytosis, splenomegaly and a frequently burdensome symptom profile. Despite current guidelines of aspirin, phlebotomy, and selective cytoreduction, many patients have inadequately controlled PV-related symptoms and/or disease features. We performed a comparison of PV symptom burden/disease feature phenotypes to understand unmet needs in current medical management. Methods Data was collected prospectively amongst an international cohort of PV patients including symptom burden, demographics, and disease features. Subgroups were identified who had previously failed hydroxyurea (PV-HU), required ongoing phlebotomy (PV-P), had palpable splenomegaly (PV-S), or had all 3 features (PV-HUPS). Control groups were derived from the remaining PV patients lacking the specified subgroup trait; patients in whom the trait status was unknown were excluded from each respective control group. All participants completed the MPN specific symptom burden questionnaire (MPN-SAF TSS (MPN-10 – Table 1)) and had no prior history of splenectomy. Surveyed symptoms on the MPN-10 included the patient's perceptions of common MPN-related symptoms and overall quality of life (QOL) on a 0 (absent) to 10 (worst imaginable) scale. PV risk scores were calculated using the 2013 criteria (Leukemia 2013). Comparison of symptoms between groups employed t-tests. Results Patient Demographics and Disease Features Between Phenotypic Groups A total of 1334 PV patients completed the MPN-10, and were assigned to categories of PV-HU (499 [37%]), PV-P (646 [48%]), PV-S (369, [28%]), and PV-HUPS (148 [12%]). The demographics between these groups were similar (comparable age (median range 60-63), PV risk scores (mean risk range: Low 16.4-23.7%; Intermediate 31.4%-36.6%; High 42.8%-47%). Mean hemoglobin was similar among PV subgroups (range 14.4-14.9); PV-HUPS had a higher mean WBC count (20.3 g/dL vs. 8.8-11.8 g/dL) and platelet count (703.5 x 10(9)/L vs. 327.5-462.8 x 10(9)/L), and disease duration (11.5 years vs. 6.4-8.8 years). Prior thrombosis was most common in PV-S patients (28.5% vs. 21.8-25.2%) and prior hemorrhage was most common in PV-HUPS patients (23.8% vs. 13.7-15.8%). Symptom Burden The MPN-10 scores of each problematic PV phenotype (HU, P, S, HUPS) were compared to the remainder of the PV cohort lacking the trait (PV-control; Table 1). Both individual symptom scores and TSS were highest for PV-HUPS patients (mean TSS 32.5 vs. 27.7-29.2). All problematic PV subgroups demonstrated significant differences for individual symptoms and TSS compared to PV-control. Comparing "problematic" subgroup responses, PV-HU patients described more inactivity whereas PV-S patients described more early satiety and pruritus. No statistical differences were noted in PV-HU, PV-P and PV-HUPS patient responses to MPN-10 items of "fever" and "weight loss". Discussion PV patients who have either failed HU, are undergoing phlebotomy and/or have splenomegaly exhibit moderate to severe symptomatology and demonstrate unmet medical need for management. As evidenced in this study, considerable overlap in symptomatology exists in PV-HU, PV-P, PV-S and PV-HUPS. Current randomized trials of JAK inhibitors have demonstrated benefits in a PV-HUPS phenotype. This data suggests that PV patients with any evidence of inadequate control (PV-HU, P, or S) have similarly unmet needs and may be candidates for clinical trials, intensification of medical therapy or perhaps JAK inhibitor therapy.

The Impact

Background: Historical treatment guidelines for the myeloproliferative neoplasm, polycythemia vera (PV), have generally not recommended cytoreductive therapy for "low risk" PV (age <60 and no prior thrombo-hemorrhagic events (TH)) on the hypothesis that decreasing the risk of TH events is the only goal of therapy for PV. The MPN-QOL Study Group has previously reported on the presence of PV associated symptoms, sometime severe, in PV including "low risk" PV patients. Recently, data from the ongoing "Low PV" interventional trial of RoPEG Interferon (INF) vs. Phlebotomy alone suggests an advantage in symptom control and event free survival in "low risk" PV patients treated on the RoPEG INF cytoreductive arm (LBA EHA 2020). Given this latter trial might alter the approach to managing "low risk" PV patients we sought to assess the symptom burden (with or without cytoreductive treatments) in that population. Methods: MPN patient data was collected prospectively amongst an international cohort of PV patients including symptom burden, demographics, and disease features collected by IRB approved de-identified survey questionnaires (N=2,017, of which 698 had PV). We analyzed data from a subgroup consistent with "low risk PV" (age <60, no prior thrombo-hemorrhagic events). All participants completed the MPN-specific symptom burden questionnaire (MPN-SAF TSS [MPN-10]) and had no prior history of splenectomy. Surveyed symptoms on the MPN-10 included the patient's perceptions of common MPN-related symptoms and overall quality of life (QOL) on a 0 (absent) to 10 (worst imaginable) scale. Results: A total of 211 "low risk" PV patients were identified, of which 140 (66.4%) had received some form of cytoreductive therapy (hydroxyurea = 54%; pegylated interferon = 44%; and anagrelide = 2%), with those patients not on cytoreductive therapy being statistically significantly younger (M=48.2±8.74 years vs. M=50.6±7.41 years), having a shorter duration of an MPN diagnosis (M=4.6±4.82 years vs. M=6.7±6.00 years), and higher hemoglobin (M=16.9±3.26 vs. M=15.2±2.37), higher hematocrit (M=50.6±9.83 vs. M=45.5±7.10), higher leukocyte (M=10.8±4.25 vs. M=7.5±4.72), and higher platelet counts (M=508.1±317.19 vs. M=327.8±190.52) at the time of MPN symptom assessment (Table 1). The entire cohort was quite symptomatic with 87% (n=184/211) of patients endorsing fatigue, but overall the PV patients on cytoreduction were more symptomatic (mean MPN-10 of 24.7 (cytoreduction) vs 18.5 (no cytoreduction) p=0.01) with significantly higher levels of fatigue (p=0.04), bone pain (p=0.04), fever (p=0.001) and weight loss (p=0.04) in cytoreductive group (Table 2). Conclusions: "Low risk" PV patients are frequently symptomatic, and an unselected series from the MPN-QOL Study Group demonstrates significant symptomatic unmet needs in this population potentially supporting the need and potential benefit of cytoreductive therapy. "Low risk" PV patients (even before the impact of the Low PV Study is realized) also have frequently been receiving cytoreductive therapies, even though they have not been included in treatment guidelines, and typically have higher symptom burden despite lower counts, are older, and have longer duration of MPNs. Drivers of the decision to use cytoreductive therapy was not captured, but it is possible longer duration of disease, higher symptom burden, intolerance of phlebotomy might all be contributing factors. These results show there is both unmet need, and frequent heterogeneity amongst "low risk" PV patients, the final results of the Low PV Study are anticipated with great interest.

Abstract Background: Thrombotic and hemorrhagic complications are commonly encountered in uncontrolled essential thrombocythemia (ET). Both anagrelide and hydroxyurea (HU) have proven efficacious in cytoreduction as well as reducing these events and remain first line therapy for most high-risk ET patients. Independent of their role in risk-reduction, little is known about how these therapies impact patient symptomatology or quality of life. In this study, we compared the clinical and symptomatic profiles of ET patients receiving HU or anagrelide against patients with no previous experience with these agents. Methods: Data was assessed from a prospectively collected international database of ET patients in which demographics, disease features, and ET symptoms utilizing the myeloproliferative neoplasm symptom assessment form (MPN-SAF; Scherber et al, 2011). The MPN-SAF includes the patient's perceptions of common MPN-related symptoms and overall quality of life (QOL) on a 0 (absent) to 10 (worst imaginable) scale. Total symptom score (TSS) was computed based on symptom items using the published scoring algorithm on a 0 (all reported symptoms absent) to 100 (all reported symptoms worst imaginable) scale. ET risk scores were calculated using the IPSET scoring algorithm (Passamonti 2012). Thrombocytopenia was defined as a platelet count <100 x 10(9)/L, anemia was defined as hemoglobin<10 g/dL and leukopenia was defined as a white blood cell count <4.0 x 10(9)/L. Associations between the MPN-SAF individual symptoms were investigated using chi-square test for categorical data and ANOVA F-test for continuous variables. Results Hydroxyurea vs. HU Naive A total of 402 ET patients with active HU use were compared to 392 ET patients with no history of HU use. Patients using HU were older (63.5 years vs. 52.3 years, p<0.001) and had a greater concentration of both high risk (24.9% vs. 11.4%, p=0.001) and intermediate risk (53.9% vs 38.4%, p<0.001) patients. They also had a higher rate of prior thrombosis (29.8% vs 11.3%, p<0.001) and leukopenia (10.1% vs. 3.0%, p<0.001). No differences were noted between gender, a history of prior hemorrhage, red blood cell transfusion requirements, or the presence of anemia/thrombocytopenia. In comparing symptom profiles, no significant differences were noted between TSS or individual symptoms with the exception of slightly more severe cough in HU patients (1.5 vs. 1.1, p=0.02, Figure 1). Anagrelide vs. Anagrelide Naive A total of 49 ET patients with active anagrelide use were compared to 794 ET patients with no history of anagrelide use. Patients using anagrelide had a longer mean disease duration (8.1 years vs. 5.8 years) and were more anemic (9.1% vs. 1.2%, p<0.001). No differences were noted between age, gender, risk scores, the presence of leukopenia/thrombocytopenia, a history of prior thrombosis or hemorrhage complications or red blood cell transfusion requirements. Additionally, there were no significant differences between TSS or individual symptom items (Figure 1). HU vs. Anagrelide A total of 402 patients currently using HU were compared to 39 patients currently using anagrelide. Overall, HU users were slightly older (63.5 years vs. 55.1 years, p<0.001) with a greater population of patients meeting high risk criteria (24.9% vs. 2.8%, p=0.002) and having a history of prior thrombosis (29.8% vs. 12.8%, p=0.02). Patients receiving anagrelide had a slightly longer disease duration (8.2 years vs. 6.0 years, p=0.0446). In comparing symptom profiles, no differences were noted in TSS or individual symptom items between cohorts. Discussion In this retrospective analysis, it does not appear cytoreduction with either HU and/or anagrelide has a significant impact on ET symptom burden despite reducing vascular events. Importantly, the higher risk scores in HU patients did not translate directly into greater patient symptomatology supporting previous studies demonstrating a poor association between these two items. Prospective trials measuring ET symptom change, in the setting of randomized trials will better quantify impact of cytoreduction on symptom burden as well as quantify impact of newer agents such as interferon or jak inhibition.

Background: Individuals with acute myeloid leukemia (AML) are at risk for significant physical and psychological burden related to their illness. While overall survival rates are improving, treatments may be associated with lengthy hospitalizations, and the risk of relapse remains substantial. This study explores cancer-related distress and concerns among AML survivors, as well as supportive care received from their healthcare team. Methods: 58 AML patients and survivors enrolled in the Cancer Support Community's online Cancer Experience Registry; 38 completed CancerSupportSource® (CSS) questions, a 25-item distress screening tool in which they rated their level of concern (0=Not at all; 4=Very seriously) about emotional well-being, symptom burden and impact, body image and healthy lifestyle, healthcare team communication, and relationships and intimacy. CSS includes validated subscales that identify individuals at risk for clinically significant depression and anxiety. Participants also completed questions about their unmet needs and desired help. Pearson's correlation coefficients were used to explore bivariate associations between socio-demographic variables and clinical history with overall distress (sum of CSS ratings) in AML respondents. Results: Mean (SD) age was 50 (14) years (range: 18-77); mean time since diagnosis was 5.6 years. Participants were 87% White and 64% female. 33% were receiving treatment at the time of taking the survey; 23% had ever experienced a recurrence of their cancer. Participants' greatest concerns (% rated Moderately to Very seriously) included: eating and nutrition (61%); exercising (57%); fatigue (53%); worry about the future and what lies ahead (51%); feeling irritable (51%); health insurance or money worries (49%); sleep problems (47%); changes or disruptions in work, school, or home life (46%); and feeling sad or depressed (45%). Based on responses to CSS risk screening subscales, more than half of participants (54%) were at risk for clinically significant level of anxiety; 42% were at risk for clinically significant levels of depression. Over half of respondents indicated their healthcare team asked about emotional concerns (58%); half said they were asked about lifestyle concerns such as diet and exercise (50%) and about financial concerns (e.g., out-of-pocket costs) (50%); roughly two-out-of-five had a health professional talk to them about employment concerns (40%) or family (42%). A majority of participants wished they had received more help with managing emotions related to cancer (67%), managing short-term (50%) and long-term (61%) side effects and symptoms, changing lifestyle behaviors (53%), and financial advice/assistance (47%). In bivariate analysis, greater overall distress was associated with younger age (r=-.49; p<.01), less education (r=-.44; p<.01), and lower annual household income (r=-.74; p<.001). Conclusions: This exploratory study demonstrates that substantial proportions of AML survivors express concerns about emotional distress, symptom burden and impact, and practical matters including finances. Yet, many report they are not counseled about these concerns, and the majority wish for more help to address these needs. Efforts are needed to enhance social and emotional support and improve access to integrated supportive care for individuals with AML, to reduce the potential impact of illness burden and distress on quality of life, treatment adherence, and other illness outcomes. Future research will examine multivariate predictors of distress and unmet needs. Disclosures Zaleta: Pfizer: Research Funding; Gilead: Research Funding; Athenex: Research Funding.

Abstract Background: Myelofibrosis (MF), polycythemia vera (PV), and essential thrombocythemia (ET), are chronic MPNs associated with a broad array of symptoms that may negatively impact patients’ quality of life (QoL). To enhance patient care, it is important to have a current and clear understanding of how MPNs affect the overall health and daily lives of patients. The MPN LANDMARK SURVEY was developed to examine patients’ perceptions of these MPNs related to disease burden, QoL, productivity, and activities of daily living (ADLs). Methods: Eligible patients diagnosed with an MPN were recruited to participate in an online survey conducted from May–July 2014in the US. Patients were asked about the overall burden of disease and impact of symptoms on their QoL, productivity, and ADLs. Descriptive analyses were conducted to assess these outcomes and examined by calculated (not reported) prognostic risk score (MF - DIPSS: Passamonti, Blood 2010; PV: Tefferi, Leuk 2013; ET - IPSET: Passamonti, Blood 2012) and symptom severity quartiles, which were determined using the MPN Symptom Assessment Form (MPN-SAF) total symptom scores. Results: 813 patients (MF=207; PV=380; ET=226) responded to the survey. A majority of patients were female (MF, 54%; PV, 62%; ET, 72%), approximately half were aged 60–74 years (MF, 55%; PV, 51%; ET, 46%), and most were covered by health insurance (>98%). Nearly half (48%) were diagnosed within the last 5 years and average time to diagnosis from first symptoms was >2 years. A high proportion of patients had intermediate to high prognostic risk scores (MF, 94%; PV, 87%; ET, 44%). The majority of patients reported feeling anxious or worried about their MPN (MF, 91%; PV, 78%; ET, 74%). Among all groups, fatigue was the most severe symptom reported (mean MPN-SAF score=6.0–6.4 on a scale of 0–10). A subset of patients in each group described their symptoms as very severe (severity score ≥7 on a scale of 0–10; MF: fatigue [59%], problems with sexual desire [49%], inactivity [46%]; PV: inactivity [48%], fatigue [49%], problems with sexual desire [49%]; and ET: problems with sexual desire [49%], fatigue [50%], headaches [40%]). The majority of patients reported that MPN-related symptoms reduced their QoL (MF, 81%; PV, 66%; ET, 57%); this was reported in all risk groups but more frequently by patients with a high risk score vs a low risk score in MF and ET (MF, 89% vs 69%; PV, 63% vs 65%; ET, 71% vs 59%). A more substantial QoL impact was reported by patients in high vs low symptom quartiles (MF, 95% vs 51%; PV, 94% vs 33%; ET, 93% vs 15%). Similarly, MPNs also had a marked negative impact on reduced work hours, sick days, voluntary job termination, receipt of medical disability, early retirement, and ADLs (Table 1). For example, among patients employed, approximately one fourth reported missing ≥1 day of work (MF, 29%; PV, 19%; ET, 23%) in the last 30 days before the survey. Even patients with low prognostic risk scores often reported missing ≥1 day of work (MF, 33%; PV, 23%; ET, 22%) or cancelling ≥1 day of planned activities (MF, 46%; PV, 35%; ET, 34%). Patients in the high vs low symptom quartiles were more likely to call in sick to work (MF, 48% vs 0%; PV, 52% vs 4%; ET, 38% vs 0%) or cancel ≥1 day of planned activities (MF, 77% vs 5%; PV, 56% vs 7%; ET, 67% vs 3%). Conclusion: The findings from this large, first-of-its-kind survey demonstrate a marked burden of disease across all 3 MPNs that is not limited to symptoms but extends to QoL, productivity, and ADLs. Although high prognostic risk scores have long been associated with a significant burden of disease, in this study, patients with a low risk score also reported significant burden. The symptom burden reported is consistent with previous studies, thus validating the present dataset. MPN treatment considerations should include reducing the symptom burden and improving QoL and productivity to enhance the overall health and lives of MPN patients.

Abstract BACKGROUND: Polycythemia vera (PV) is characterized by increased red cell mass often associated with elevated leukocyte and platelet counts, splenomegaly and significant symptom burden. In the RESPONSE study, which only enrolled PV patients with splenomegaly, ruxolitinib (Rux) demonstrated superior improvements in hematocrit (HCT) control and reductions in spleen volume compared with best available therapy (BAT) in pts who were resistant to or intolerant of HU. Supportive data included clinically meaningful improvements in PV-related symptom burden and quality of life (QOL) measures. Here, we describe the baseline (BL) characteristics and symptom burden of PV pts resistant to or intolerant of HU enrolled in the RESPONSE-2 study, which unlike RESPONSE, enrolled PV patients with a nonpalpable spleen. METHODS: RESPONSE-2 is an open-label, randomized (1:1), multicenter, phase 3 study evaluating the efficacy and safety of Rux vs BAT in PV pts who are HU-resistant/-intolerant, require phlebotomy (PBT), and have no palpable spleen. Pts' BL symptom burden, BL QOL and BL pt-reported outcomes (PRO) were assessed by using 10-items modified Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPN-SAF TSS), the Pruritus Symptom Impact Scale (PSIS), European QOL Questionnaire (EQ-5D-5L), and Work Productivity and Activity Impairment: Polycythemia Vera V2.0 (WPAI: PV). RESULTS: A total of 149 pts were enrolled. BL demographic data from both arms combined are summarized in the Table. Forty percent of the patients were resistant whereas 60% were intolerant of HU treatment. Other than HU, prior treatments included interferons (15.4%), alkylating agents (8.1%), alkyl sulfonates (2.7%), pyrimidine analogs (0.7%), and other antineoplastic agents (1.0%). Ninety-seven percent of pts had at least 1 PBT within 16 weeks (wks) prior to screening and 72% had ≥ 2 PBT within 24 wks prior to screening. Past medical histories included hypertension (49%), pruritus (23%) and fatigue (9%). BL demographics of pts in RESPONSE-2 were generally comparable with previous PV studies (Table). Despite using frequent phlebotomy and cytoreductive agents during the screening period prior to randomization, 55% and 52% of pts had WBC counts greater than 10 × 109/L and platelet counts greater than 400 × 109/L, respectively, suggesting inadequately controlled disease even while receiving therapy. Additionally, pts had significant symptom burden at BL as measured by the MPN-SAF with fatigue (3.6) and pruritus (3.4) (Table). As measured by EQ-5D-5L scale, 26% and 19% of pts reported moderate to extreme pain/discomfort and depression, respectively. In WPAI outcomes, 40 of 149 pts reported missing work due to PV accounting for 14.3% of their working time. SUMMARY/CONCLUSION: Demographic and BL data from the RESPONSE-2 study highlight the significant unmet medical need in this inadequately controlled HU-resistant/-intolerant PV population. As expected, pts in RESPONSE-2 reported lower scores for symptoms associated with splenomegaly (early satiety, 1.8 vs 2.0; abdominal discomfort, 1.7 vs 2.0) as compared with RESPONSE population. In comparison to PV pts with splenomegaly in the RESPONSE trial, pts without splenomegaly in the RESPONSE-2 trial have a distinct but comparable disease burden with marked fatigue and pruritus.

Daratumumab (DARA) is a CD38-targeted antibody FDA-approved for the treatment of multiple myeloma (MM) and its efficacy has recently been demonstrated in the treatment of AL amyloidosis. DARA is conventionally given indefinitely until evidence of disease progression or intolerance for the treatment of MM. In AL amyloidosis, the optimal duration of therapy is not known, and patients may be treated indefinitely on maintenance, extrapolating from MM data. However, the plasma cell burden observed in AL amyloidosis is often lower than in MM, and thus certain patients achieving deep responses may have durable responses with time-limited treatment. Outcomes for patients who are observed after DARA discontinuation are not known. We report the outcomes of patients at our institution who received time-limited DARA. A retrospective analysis of AL amyloidosis patients treated at Stanford University from 2016 to 2019 with DARA monotherapy and dexamethasone for at least 2 months was performed, and patients who subsequently had DARA discontinued for reasons other than disease progression or lack of response were selected for the study. Hematologic responses were assessed by consensus guidelines. Duration on and off therapy were explored, along with time-to-next treatment or death (TTNT), defined as the time from DARA initiation to restarting/switching therapy or death. An exploratory analysis comparing TTNT between the study population and a control cohort who achieved hematologic CR and were maintained on DARA was conducted with the Kaplan-Meier method and log-rank testing. 67 patients received at least 2 months of DARA monotherapy and dexamethasone; among these, 15 patients discontinued therapy for reasons other than disease progression and were included. Median age was 66 years old and median lines of prior therapies was 4 (range: 1 - 6). Baseline difference between involved and uninvolved free light chains (dFLC) prior to DARA initiation was 2.6 mg/dL (range: 0 - 16.8 mg/dL). 10 of 15 patients had cardiac involvement with median NT-proBNP of 1982 pg/mL and 9 of 15 patients had renal involvement with median 24-hour proteinuria of 6.2 g and eGFR of 32 mL/min/1.73m2 at DARA initiation. Median duration from starting to stopping DARA was 7.8 months (range: 2 - 21 months). Median duration from achieving best hematologic response to stopping DARA was 3 months (range: 0 - 17 months). Reasons for discontinuation included: patient preference (5), fatigue/body aches (4), infection (2), other active medical comorbidities (3), and lack of perceived further benefit (1). At DARA discontinuation, median dFLC was 0.1 mg/dL (range: 0 - 2.2 mg/dL) and there were 12 hematologic CR, 1 VGPR, 1 PR, and 1 not assessable for response. Outcomes for all 15 patients are shown in Figure 1. The median treatment-free interval was 17.5 months (range: 5 - 34 months); estimated 2-year TTNT-free survival was 83% (95% CI: 61 - 100%). All 14 evaluable patients eventually achieved CR. 3 patients restarted DARA for rising dFLC, and all 3 patients demonstrated response to retreatment (2 achieving CR and 1 near PR with ongoing follow-up). There were 2 deaths. One patient with severe baseline cardiac amyloidosis developed sudden rise in dFLC after treatment-free interval of 21 months; although he rapidly achieved hematologic CR on retreatment, he died of heart failure within 2 months of restarting DARA. The other patient developed therapy-related AML while off therapy and underwent allogenic stem cell transplant but died of leukemia (censored for AL amyloidosis outcomes at transplant). There was no significant difference in the TTNT between the study group and a control group of 16 patients who achieved CR and were on continuous maintenance (Figure 2; p=0.807). AL amyloidosis patients achieving deep responses with DARA can have favorable outcomes after treatment discontinuation, including a long treatment-free interval. Although our sample size is small, the outcomes of these patients appeared comparable to those achieving CR on continuous DARA maintenance, and patients were able to regain responses when retreatment was necessary. These results suggest that DARA may be safely discontinued in patents achieving deep hematologic responses, which has significant implications for quality of life and financial burden of treatment. Future studies evaluating time-limited versus continuous DARA maintenance after achievement of deep responses are warranted. Disclosures Kaufman: Janssen: Other: travel/lodging, Research Funding.

Therapy Initiation

Background: Myelofibrosis (MF) is a chronic Philadelphia chromosome-negative myeloproliferative neoplasm (MPN) characterized by extramedullary hematopoiesis, bone marrow fibrosis, splenomegaly, constitutional symptoms, and diminished quality of life. Treatment decisions may involve a variety of factors including prognosis and symptomatology. Data regarding real-world disease and demographic factors that contribute to therapy initiation and choice in pts with lower risk MF are limited. This analysis of data from the ongoing Myelofibrosis and Essential Thrombocythemia Observational STudy (MOST; NCT02953704) assessed whether these factors differ for lower risk pts who were treated vs untreated at enrollment. Methods: MOST is a longitudinal, noninterventional, prospective, observational study in pts with MF or essential thrombocythemia enrolled at clinical practices within the US. Pts included in the analysis (≥18 y), had low risk MF by the Dynamic International Prognostic Scoring System (DIPSS; Blood. 2010;115:1703), or intermediate-1 (INT-1) risk by age >65 y alone. Pt data were entered into an electronic case report form during usual-care visits over a planned 36-month observation period. Pt-reported symptom burden was assessed using the MPN-Symptom Assessment Form (MPN-SAF); Total Symptom Score (TSS) was calculated (0 [absent] to 100 [worst imaginable]; J Clin Oncol. 2012;30:4098). Data were analyzed with basic descriptive and inferential statistics. Results: Of 233 pts with MF enrolled at 124 sites between 11/29/2016 and 03/29/2019, 205 were included in this analysis; 28 were excluded for being INT-1 risk for reasons other than age. Of the 205 pts, 85 (41.5%) were low- and 120 (58.5%) were INT-1 risk; 56.5% (48/85) and 59.2% (71/120), respectively, were being treated at enrollment. Pt characteristics are listed in Table 1A. Fewer low- vs INT-1 risk pts were JAK2 V617F or MPL positive, and more were CALR positive. The proportion of pts with palpable splenomegaly was similar for treated low- and INT-1 risk pts. In low risk pts, the proportion of pts with palpable splenomegaly was higher in untreated vs treated pts; whereas, in INT-1 risk pts, the opposite was observed (ie, lower proportion in untreated vs treated pts). Blood counts were generally similar across cohorts, except median leukocytes were lower for low risk treated pts and platelet counts were elevated in low- vs INT-1 risk pts. The proportion of pts with comorbidities was similar across cohorts, except for fewer cardiovascular comorbidities in low- vs INT-1 risk pts. Mean TSS was lower in low- vs INT-1 risk pts, but the proportion of pts with TSS ≥20 was greater in treated vs untreated pts in both low- and INT-1 risk groups. Fatigue was the most severe pt-reported symptom in all cohorts. Differences in mean TSS and individual symptom scores between risk groups were not significant (P > 0.05), except itching was worse among INT-1 risk pts (P=0.03). Physician-reported signs and symptoms were generally more frequent for untreated vs treated pts, irrespective of risk (all P > 0.05). Most low risk (69.4%) and INT-1 risk pts (61.2%) who were currently untreated at enrollment had not received any prior MF-directed treatment (Table 1B); the most common prior treatment among currently untreated pts was hydroxyurea (HU) in both risk groups. Of currently treated pts, HU was the most common MF-directed monotherapy at enrollment in low-risk pts, and ruxolitinib was most common in INT-1 risk pts. No low risk pts and few INT-1 risk pts were currently receiving >1 MF-directed therapy at enrollment. Conclusion: These real-world data from pts with MF enrolled in MOST show that a substantial proportion of both low- and INT-1 risk pts who had received treatment before enrollment were not being treated at the time of enrollment. Although watch-and-wait is a therapeutic option, the finding that many of these lower risk pts had in fact received prior therapies suggests an unmet need for effective and tolerable second-line treatment options. Treated pts had greater pt-reported symptom burden vs untreated pts, which suggests that high symptom burden may contribute to the decision for treatment. Prospective studies are needed to evaluate symptom burden change with therapy initiation. In this regard, future analyses of data from MOST are planned to assess the longitudinal evolution of the clinical characteristics, treatment patterns, and management of pts with MF.

Abstract Abstract 2931 Background: The incidence of sMDS is increasing due to improved survival of patients (pts) treated with chemotherapy (CT) or radiotherapy (RT) for other cancers. While studies have demonstrated hematologic improvement (HI) and survival benefits of AZA in pts with primary MDS (pMDS) (Lancet Oncol 2009;10:223), the effects of AZA in sMDS, considered rarer (5-10% of MDS diagnoses) (J Natl Cancer Inst 2008;100:1542) and more difficult to treat, are unknown. AVIDA, a longitudinal, US, multicenter, prospective registry of pts in community-based clinics receiving AZA, is the largest database of AZA-treated pts in the world and includes a large cohort of sMDS pts. We compared the tolerability of and response rates to AZA in sMDS vs pMDS pts in the AVIDA database. Methods: MDS pt data were collected at registry entry (baseline), and then quarterly using electronic data capture, between October, 2006 and July, 2010. Treating physicians determined AZA dose, dosing schedule, and treatment duration. Baseline characteristics of sMDS and pMDS pts were evaluated but formal statistical tests comparing cohorts were intentionally not performed to avoid Type I errors. Rates of IWG-2000-defined HI or possibly better responses (HI+) were assessed centrally and compared between sMDS and pMDS cohorts (each assessment included only pts eligible for improvement). RBC and platelet transfusion independence (TI) were also evaluated between groups using logistic regression analyses with patients stratified by International Prognostic Scoring System (IPSS) scores (higher [score >1] vs lower [score ≤1]) and transfusion status at baseline, with age and months since diagnosis included as covariates. Odds ratios (sMDS to pMDS) and 95% confidence intervals (CI) were reported from these models. Results: At data cut-off in July 2010, 37/417 pts (8.9%) in the registry had sMDS associated with exposure to RT, CT, or radioiodine (n=33), benzene (n=2), or radiation (n=2). Median times since diagnosis for pts with sMDS and pMDS were 1 month (range 0 – 69) and 3 months (0 – 207), and median ages were 71 years (range 41 – 86) and 75 years (29 – 91), respectively. At baseline, for pts with available IPSS scores, a larger proportion of pts with sMDS than pts with pMDS had IPSS higher-risk scores (55% vs 30%) and IPSS poor cytogenetics (59% vs 17%). Additionally, a higher proportion of sMDS vs pMDS pts had chromosome 7 abnormalities (47% vs 11%), 2–3 cytopenias (76% vs 62%), and infections requiring IV antibiotics (41% vs 16%); but similar proportions had >10% blasts (18% of both cohorts) and were dependent on RBC (57% vs 52%) and platelet (22% vs 13%) transfusions at baseline. Median follow-up was 5.9 months (range 0.2 – 24) in the sMDS and 6.7 months (0.1 – 37) in the pMDS cohorts, and median numbers of AZA treatment cycles were 4 (range 1 – 21) and 5 (1 – 26), respectively. In both the sMDS and pMDS groups, the most common treatment dose and schedules were 75 mg/m2 AZA (91% and 83%, respectively) for 5 consecutive days (46% and 55%) in ≤28-day cycles (45% and 54%). Pts with sMDS had a high rate of HI+, which was comparable to that in pts with pMDS (Table). Rates of RBC TI in baseline RBC transfusion-dependent pts with sMDS vs pMDS were 57% vs 61%, and of platelet TI for baseline platelet transfusion-dependent sMDS vs pMDS pts were 50% vs 64% (Table). Odds ratios from the logistic regression models were 1.4 (95%CI: 0.6, 3.5; p=0.47) and 0.6 (95%CI: 0.2, 1.4; p=0.23) for RBC TI and platelet TI, respectively, after adjusting for the other covariates in the model. Grade 3 or 4 adverse events were similar in the 2 groups, with the exception of higher frequencies of thrombocytopenia (27% vs 11%) and infections (24% vs. 12%) in sMDS vs pMDS pts, respectively. Conclusion: Pts with sMDS treated with AZA had rates of HI or better responses comparable to those of pMDS patients, despite worse pretreatment disease characteristics. AZA was well tolerated by pts with sMDS and pMDS. A diagnosis of sMDS alone should not preclude treatment with the disease-modifying drug, azacitidine.

Abstract Background Peripheral T-cell lymphoma (PTCL) is an aggressive and heterogeneous subtype of non-Hodgkin lymphoma (NHL). PTCL has a poor prognosis due to advanced stage at presentation, and generally poor response to standard chemotherapy. According to recent SEER estimates, PTCL accounts for about 4% of all NHL cases in the United States each year. To date, few studies have assessed the clinical and economic burden of PTCL. Methods MarketScan data for commercially insured and Medicare supplemental patients were used to retrospectively identify unique PTCL patients. Patients were identified by ICD-9-CM diagnosis codes between October 1, 2007 and June 30, 2011. The time of first PTCL diagnosis code served as the index date, and a second PTCL diagnosis date was used for confirmation. All patients were required to have at least 6 months of continuous enrollment before and 12 months of continuous enrollment after their index date. Patients were excluded if aged <18 years, date of birth or gender were missing, or if they had received a stem cell transplant (SCT) prior to PTCL diagnosis. The control group includes patients that may have any other malignant (excluding PTCL) or non-malignant condition and are considered to represent an average insured patient population from the payer perspective. The control group was matched based on age, sex, region, plan type, payer type, and length of enrollment. Mean cost per month was measured and annualized to provide average yearly costs. Healthcare costs included hospitalizations, pharmacy services, office visits, emergency room visits, hospice stays, SCT, and other patient-related costs (lab procedures, radiology procedures, blood transfusions, and other ancillary procedures). Results Of 2820 patients with ≥1 PTCL diagnosis, 1000 patients were identified that met all inclusion criteria (mean age 56 years, 58% male), and were matched to the control group. On an average annual basis, PTCL patients were hospitalized more often (0.9 vs 0.1 hospitalizations), and experienced a longer length of stay (6.4 vs 4 days) compared with matched controls. In addition, PTCL patients had a higher utilization of office visits (16.2 vs 4.1 visits), pharmacy services (34.2 vs 11.6 prescriptions), emergency room visits (0.8 vs 0.2 visits), and hospice care (0.6 vs 0.1 stays). PTCL patients also experienced higher comorbidities (mean Charlson Comorbidity Index of 1.72 vs 0.39, as determined at index date). Overall, PTCL patients incurred much higher average annual costs compared with matched patients ($75,934.08 vs $4660.64; Table), driven mainly by hospitalizations (32.2% of overall costs) and pharmacy services (19.6% of overall costs). Conclusions PTCL is associated with high resource utilization rates and high overall costs. The development of efficacious treatments for PTCL may offer better disease management and may reduce the clinical and economic burden of PTCL.

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.
