Symptom Burden and Quality of Life in High-Risk Essential Thrombocythemia and Polycythemia Vera Patients Receiving Hydroxyurea or Pegylated Interferon Alfa-2a: Results of Myeloproliferative Neoplasms Research Consortium (MPN-RC) 111 and 112 Trials

Introduction Essential thrombocythemia (ET) and polycythemia vera (PV) patients suffer from various symptoms that worsen quality of life (QOL), yet serial data on symptom changes resulting from therapy are sparse in the literature. Patient questionnaires from 2 large multicenter trials (MPN-RC 111, 112) were used to assess change in symptom burden and QOL over 12 months and impact of baseline symptom burden on subsequent change in ET / PV patients on hydroxyurea (HU) or pegylated interferon alfa-2a (PEG). Methods Trials MPN-RC 111 was a single-arm, open-label, phase II trial evaluating response to PEG in high-risk ET / PV patients with HU resistance/intolerance or splanchnic vein thrombosis (SVT; NCT01259817). MPN-RC 112 was a randomized, open-label, phase III trial comparing response to PEG versus HU in cytoreductive therapy naïve high-risk ET / PV patients diagnosed < 5 years ago (NCT01258856). Measures Patients reported disease-related symptoms via the validated Myeloproliferative Neoplasms Symptom Assessment Form (MPN-SAF), QOL via the European Organisation for the Research and Treatment of Cancer Core QOL Questionnaire (EORTC QLQ-C30), and (if applicable) PEG-related symptoms (flu-like symptoms, injection site irritation, blurry vision, vision change, flushing) at baseline, 3, 6, 9, and 12 months. Analysis Mixed models assessed mean changes from baseline in the MPN-SAF Total Symptom Score (TSS), MPN-SAF items, QOL, and PEG-related symptoms in MPN-RC 111, 112 PEG, and 112 HU patients. Mixed models also assessed the impact of baseline symptom burden (high [TSS ≥ 20] versus low) on subsequent change in PEG (MPN-RC 111 and 112) and HU patients. Results Patients Of the 135 enrolled MPN-RC 111 patients, 20 with SVT and 1 with no questionnaires were excluded. Of the remaining 114, 64 (56%) / 50 (44%) had ET / PV. Patients were 51% / 48% female. Median age was 65 / 64 years, and median time since diagnosis was 38 / 55 months. 31% / 22% had prior thrombosis, and 19% / 56% had splenomegaly. Of the 168 enrolled MPN-RC 112 patients (82 PEG, 86 HU), 2 with no questionnaires were excluded. Of the remaining 166, 79 (48%) / 87 (52%) had ET / PV. Patients were 50% / 33% female. Median age was 60 / 62 years, and median time since diagnosis was 3 / 3 months. 25% / 29% had prior thrombosis, and 11% / 37% had splenomegaly. Symptoms Questionnaire completion rates ranged from 90 - 99%, 87 - 100%, and 75 - 96% for on-treatment MPN-RC 111, 112 PEG, and 112 HU patients. At baseline, TSS (0 [absent] - 100 [worst imaginable]) and QOL (0 [very poor] - 100 [excellent]) means (SDs) were 19.5 (18.4) and 71.6 (20.1) for MPN-RC 111, 17.0 (13.6) and 67.9 (24.3) for MPN-RC 112 PEG, and 14.6 (11.4) and 73.8 (18.8) for MPN-RC 112 HU patients. On average, MPN-RC 111 patients had significant improvement of TSS, fatigue, abdominal pain, abdominal discomfort, dizziness, numbness, night sweats, and fever; MPN-RC 112 PEG patients had significant worsening of fever; and MPN-RC 112 HU patients had significant worsening of inactivity (no mean changes indicating improvement were observed). PEG patients had significant worsening of PEG-related symptoms. The greatest improvements occurred in the 46 (40%), 27 (33%), and 23 (28%) MPN-RC 111, 112 PEG, and 112 HU patients with high baseline symptom burden. On average, PEG patients with high baseline symptom burden had significant improvement of TSS, fatigue, early satiety, abdominal pain, abdominal discomfort, inactivity, headache, concentration, dizziness, numbness, insomnia, cough, night sweats, itching, bone pain, fever, weight loss, and QOL, while those with low baseline symptom burden had significant worsening of TSS, early satiety, headache, itching, and bone pain. On average, HU patients with high baseline symptom burden had significant improvement of TSS, early satiety, abdominal discomfort, headache, dizziness, numbness, insomnia, itching, and weight loss, while those with low baseline symptom burden had significant worsening of TSS, early satiety, abdominal discomfort, inactivity, concentration, and sexual desire/function (Figures 1 and 2). Conclusions Although no statistical comparisons were made across trials, overall improvements were seen in MPN-RC 111 but not 112. Patients with high baseline symptom burden experienced the greatest improvements in symptom burden and QOL during treatment with PEG or HU, which may explain the improvements seen in the more advanced patients in MPN-RC 111 compared to 112.

Abstract Abstract 1739 BACKGROUND: Differences in symptom burden characteristics between persons of European and non-European descent with BCR-ABL negative MPNs including essential thrombocythemia (ET), polycythemia vera (PV), and primary myelofibrosis (MF) are not studied. We reported significant clinical and laboratory differences between these populations age at diagnosis and survivals (Blood 2011;119: 2469–73) which could affect symptom burden. Given China represents one-fifth of the global population, we aimed to evaluate MPN symptom burden among a cohort of Chinese MPN patients. METHODS: Data were collected from Chinese with MPNs and their physicians and compared these to a previously collected data from a cohort of subjects of predominately European descent (N=1488). Subject data included MPN-SAF (Blood 2011;118:401-8) and BFI score (Cancer 1999;85: 1186–96), demographics, and disease-related features. Statistical methods included ANOVA, chi-squared tests, and multiple regressions. RESULTS: Demographic and Disease Characteristics: 397 Chinese subjects were prospectively enrolled with a distribution of 172 (43%) ET, 102 (26%) PV, and 123 (31%) MF (of which 103 [84%] were PMF, 14 [11%] were post-ET MF, and 6 [5%] were post-PV MF). Median age (56.0 y) was younger in Chinese than in the European-descent cohort (63.0 y, p<0.001) despite relative gender equality. Laboratory abnormalities including anemia (76%, p<0.001) and disease features including bleeding (1%, p<0.001), were more common and present at a significantly higher incidences in the European-descent cohort than amongst Chinese. Chinese Symptom Severity and Incidence by MPN type: When comparing across MPN types, symptoms of worst fatigue, early satiety, abdominal discomfort, inactivity, concentration, depression, cough, night sweats, weight loss, and total MPN-SAF TSS score varied significantly (p<0.05) with MF being most severe for each symptom. Chinese versus European-descent Symptom Severity: After adjusting for age and MPN type, Chinese subjects had significantly higher mean severity for fever, sexual difficulties, and quality of life (Table 1). Symptoms of worst fatigue, early satiety, abdominal discomfort and overall BFI score had a significantly higher mean severity in the European descent cohort. Chinese versus European-descent Symptom Incidence: The European-descent cohort had significantly greater incidence of worst fatigue (90% vs 81%, p<0.001), abdominal pain (47% vs 35%, p<0.001), early satiety (65% vs 57%, p=0.005), concentration problems (64% vs 58%, p=0.04), numbness (63% vs 56%, p=0.02), insomnia (68% vs 58%, p<0.001), and depression (62% vs 56%, p=0.02) compared to Chinese subjects. In contrast, symptoms of dizziness (63% vs 57%, p=0.04), sexual difficulties (72% vs 61%, p<0.001), and fever (23% vs. 18%, p=0.03) were significantly worse amongst Chinese. CONCLUSION: We found a significant divergence in severity and incidence of key symptom burdens including QOL, fever, sexuality, dizziness, abdominal pain, early satiety, and fatigue between Chinese and persons of European descent with MPNs. Biological and cultural factors likely account for these differences and should be considered when interpreting outcomes of clinical trials of diverse populations. When the target of therapy is reversing symptoms, the best strategy may require revision for different populations.

Abstract Background: Patients who undergo allogeneic hematopoietic cell transplantation (allo-HCT) are at high risk of reactivation or de novo infection with double-stranded (ds) DNA viruses such as cytomegalovirus (CMV), Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6), adenovirus (AdV), BK virus (BKV), and JC virus (JCV). After allo-HCT, up to 90% patients develop detectable viremia by PCR. EMR data collected between 2018 and April 1, 2021, from over 1400 high-risk allo-HCT patients at 21 US centers suggest that 40-50% develop clinically significant viral infection or disease associated with ≥1 of these dsDNA viruses within 200 days of transplant. Multiple studies demonstrate increased morbidity and mortality associated with viremia, with or without end-organ disease. Prophylactic and preemptive therapies have substantial side effects and can lead to the development of resistance, especially in CMV. HCT donor-derived virus-specific T-cells have shown promise in preventing single virus infections in prior clinical trials but were infeasible for wide-scale use. There is an urgent unmet medical need for preventive strategies targeting multiple viruses in patients undergoing high-risk allo-HCT. Methods: We are conducting a clinical trial (NCT04693637) to evaluate the safety and efficacy of posoleucel (ALVR105, Viralym-M) for preventing clinically significant viral infections due to CMV, EBV, HHV-6, AdV, BKV, and JCV in high-risk allo-HCT recipients. Posoleucel is an ex-vivo expanded, partially HLA-matched, off-the-shelf, multivirus-specific T cell investigational product generated from healthy, third-party donors targeting CMV, EBV, HHV-6, AdV, BKV, and JCV. In the open-label portion of the study, patients receive up to seven infusions of 4×10 7 cells of posoleucel administered once every 14 days. High-risk patients are those who received a graft from a sibling or unrelated donor with ≥1 HLA mismatch; from a haploidentical donor; from umbilical cord blood or with T-cell-depletion; as well as patients with lymphocytes <180/mm 3 or CD4 T cells <50/mm 3 at enrollment. Patients must be engrafted and within 15-49 days of allo-HCT. Those with grade ≥3 GVHD as well as those requiring steroids (>0.5 mg/kg/day prednisone equivalent) at enrollment are ineligible. Patients are tested weekly for viremia using quantitative PCR assays and are monitored every other week for adverse events. The primary endpoint is the number of clinically significant viral infections or episodes of end-organ disease due to CMV, EBV, HHV6, AdV, BKV, or JCV by week 14. Results: Data are available for 12 of 25 planned participants thus far (Table 1). No patient developed a clinically significant infection within 14 weeks, the primary study endpoint. Over the entire study duration, defined as the primary 14-week treatment period plus the additional 12-week follow-up, 11 (92%) patients have remained free of any clinically significant viral infections, the key secondary endpoint. One patient, a 49-year-old female haploidentical transplant recipient, developed clinically significant AdV viremia after receiving over a month of high-dose methylprednisolone exceeding 0.5 mg/kg/day for recurrent aGVHD. This patient was administered IV cidofovir in week 15 of the study. During the primary study efficacy period one participant received 2 doses of valganciclovir following transient CMV viremia deemed not to be clinically significant by the principal investigator. Posoleucel has been well tolerated to date, with no drug-related serious adverse events, new-onset acute GVHD, or cytokine release syndrome. Safety and efficacy data from the entire open-label cohort will be presented. Conclusions: Preliminary results in this open-label cohort show that in high-risk allo-HCT patients receiving off-the-shelf posoleucel, clinically significant viral infections or disease from the 6 targeted dsDNA viruses were uncommon. No clinically significant infections were observed among participants treated in accordance with the protocol. These results, combined with the favorable safety and tolerability profile of posoleucel, support its continued evaluation in high-risk allo-HCT recipients for the prevention of CMV, EBV, HHV6, AdV, BK virus, or JC virus infection and disease.

Background: Essential thrombocythemia (ET) is a chronic myeloproliferative neoplasm (MPN) characterized by thrombocytosis and increased risk of thrombotic events and hemorrhage. Treatment of ET is risk-adapted, focused on preventing thrombosis, bleeding, and minimizing symptoms. Real-world data regarding factors contributing to treatment initiation and therapy choice in this setting are limited. Here, we present the clinical characteristics of low- and high-risk pts with ET enrolled in Myelofibrosis and Essential Thrombocythemia Observational STudy (MOST) and assess whether these differ for pts who were treated vs untreated at the time of enrollment. Methods: MOST (NCT02953704) is an ongoing multicenter, non-interventional, longitudinal, prospective, observational study in pts with specific risk categories of ET or MF. Pts included in this analysis met modified ELN criteria (J Clin Oncol. 2011;29:761) for high-risk ET (age ≥60 y and/or thromboembolic event [TE] history) or low-risk ET if receiving ET-directed therapy (not including aspirin only). Data from pt records were entered into an electronic case report form during usual-care visits over a planned observation period of 36 months. Patient-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 1235 pts with ET enrolled at 124 sites between 11/29/2016 and 12/31/2018, 1210 were included in the analysis; 25 were excluded (low-risk receiving aspirin alone [n=16]; low risk receiving neither ET-directed therapy nor aspirin [n=8]; BCR-ABL mutation-positive [n=1]). Of the 1210 pts analyzed, 159 (13.1%) were low-risk (all treated), 887 (73.3%) were high-risk and treated, and 164 (13.6%) were high-risk and untreated, respectively. Reasons for high-risk categorization were similar for treated and untreated high-risk pts (age ≥60 y, 67.5% vs 70.1%; TE history, 8.8% vs 10.4%; both age ≥60 y and TE history, 23.7% vs 19.5%). Pt characteristics are listed in Table 1A. Compared with low risk pts, significantly more high risk pts were JAK2 V617F positive (P = 0.0143); fewer were CALR positive, and more were MPL positive. Pts with high-risk disease who were untreated had the highest proportion of palpable splenomegaly; mean palpable spleen length below the costal margin was greater in treated pts (low- and high-risk) than in untreated pts. Blood counts were similar across cohorts, except platelets were elevated for untreated high-risk pts. The proportion of pts with comorbidities was similar across cohorts; cardiovascular comorbidities were not as common among low- vs high-risk pts. Mean TSS was highest for low-risk pts, and was similar in both treated and untreated high-risk pts. Fatigue was the most severe symptom in all cohorts. Mean MPN-SAF TSS was significantly higher for low- vs high risk pts (P = 0.0007), as were several individual symptom scores (abdominal discomfort, P = 0.0081; concentration, P = 0.0014; numbness/tingling, P = 0.0361; night sweats, P < 0.0001; itching, P = 0.0131; bone pain, P = 0.0206; weight loss, P = 0.0469). Physician-reported signs and symptoms were generally more common in low- vs high-risk pts, with differences between risk groups reaching significance for headache (P = 0.0009) and abdominal pain (P = 0.0455). Among currently untreated high-risk pts, 40.9% had not received any previous ET-directed therapy. Hydroxyurea (HU) was the most common ET-directed monotherapy at enrollment in both low- and high-risk treated pts (Table 1B). A small proportion of pts in both low- and high-risk treated groups was receiving >1 ET-directed therapy. Conclusion: These real-world data from the MOST study indicate that despite treatment, low-risk pts had greater patient-reported symptom burden and physician-reported signs/symptoms than high-risk (treated or untreated) pts. This finding suggests that current management (most commonly with HU in this analysis) may not address symptoms in low-risk pts. Notably, nearly 60% of currently untreated high-risk pts had been previously treated, highlighting an unmet need for effective and tolerable second-line treatments in pts with high-risk ET. Further analyses from MOST will help define changes in the clinical and treatment characteristics of pts with ET over time.

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.

Phase 2 Trial

Background. Polycythemia vera (PV) patients are treated with periodic therapeutic phlebotomy (TP) in order to maintain hematocrit levels <45% in an effort to reduce the incidence of thrombotic events [Marchioli NEJM 2013]. Since, they are seen periodically, PV patients likely spend significant time with hematocrit levels >45%, thereby potentially increasing their risk of thrombosis. Symptomatic iron deficiency represents a challenge in PV as it is commonly present at diagnosis [Ginzburg Leukemia 2018] and worsens after repeated and/or frequent TP, and often symptomatic from their iron deficiency. We hypothesized that both iron deficiency and expanded erythropoiesis in PV lead to suppression of hepcidin, the body's main negative regulator of iron metabolism, and that hepcidin suppression enhances iron absorption and availability for enhanced erythropoiesis in TP-requiring PV patients. We previously demonstrated that PTG-300, a hepcidin-mimetic, caused dose-related anemia in preclinical studies. In a phase 2 trial in β-thalassemia, PTG-300 leads to a sustained (3-7 days) decrease in serum iron and transferrin saturation (TSAT) but did not demonstrate off-target effects. The current study aims to compare the iron status and phlebotomy requirements in high TP-requiring PV patients before and during treatment with PTG-300 (Figure 1). Methods. PTG-300-04 is a 3-part Phase 2 trial consisting of (1) a 28-week dose-finding; (2) a 12-week blinded randomized withdrawal (1:1) PTG-300 vs placebo; and (3) a 52-week open label extension (Figure 1). Eligibility criteria include PV diagnosis (by 2016 WHO criteria) and ≥3 phlebotomies with or without concurrent cytoreductive therapy to maintain hematocrit ≤45% in the 24 weeks prior to enrollment. PTG-300 doses of 10, 20, 40, 60 and 80 mg administered subcutaneously weekly were adjusted to maintain hematocrit <45%. Results. Thirteen subjects were enrolled to date: 7/13 with low risk, mean age 57.4 years (range 31-74). Six receiving TP alone, 6 concurrent hydroxyurea, 1 on concurrent interferon; TP in the 24 weeks prior to enrollment = 3-9; median time between TP = 42 days. After instruction, each of the patients self-administered the drug at home. Eight subjects have been treated for ≥3 months with PTG-300 (Figure 2a). Three subjects have been randomized. During the open label dose finding portion of the study, all subjects were phlebotomy-free with the exception of one subject. Three subjects completed part 1 (28 weeks) with no TP as compared to 3-5 TP required in a similar period prior to study initiation. During the 28-week dose-finding period, the hematocrit was continuously controlled below 45% in all but two subjects' (Figure 2b). Two subjects had hematocrits transiently >45% but remained below 45% after phlebotomy in one and dose increase in both. Furthermore, erythrocyte numbers decreased (Figure 2c) and MCV increased in all but two subjects. These findings suggest a redistribution of iron within erythropoiesis. Lastly, prior to treatment, mean iron-related parameters were consistent with systemic iron deficiency while serum ferritin increased progressively toward normal range. Most frequent adverse events were injection site reaction (ISR) reported by three patients. Most of the reactions were grade 1-2 and were transient in nature and no patient discontinued the drug. Conclusions. The current results indicate that PTG-300 is an effective agent for the treatment of PV, reversing iron deficiency and eliminating the need for TP in PV patients. Elimination of TP requirements for 7 months in TP-dependent PV patients is significant and unexpected. The effect of PTG-300 on PV-related symptoms is also being evaluated. Continued patient enrollment will enable more definitive conclusions regarding the efficacy and safety of hepcidin mimetic PTG-300 in PV patients with high TP requirements. PTG-300 looks very promising in eliminating the therapeutic phlebotomies in both low and high-risk patients.

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.

Background: Quality of life (QOL) is predictive of survival in many malignancy types, including myeloproliferative neoplasms (MPNs; Scherber 2017, Sloan 2012, Montazeri 2009, Nilsson 2017). We have previously characterized that an association exists between symptom burden and QOL among MPN patients, but due to the disease specificity of symptoms, symptoms rather than QOL remains a key therapeutic endpoint (Scherber 2017, NCCN Guidelines). Despite these advancements, our understanding of the extent that different patient and disease characteristics, including symptoms, contribute to overall QOL has remained elusive. In this analysis, we utilized information from a large survey of MPN patients to develop a model of QOL that establishes the degree that individual variables contribute to QOL, including psychosocial variables, comorbidities, and MPN disease symptoms. Methods: The FATIGUE survey of MPN patients (Scherber 2016) investigated self-reported symptoms using the MPN10 (Scherber 2012), depression utilizing the Profile of Mood States-Brief (POMS-B, McNair 1971), Patient Health Questionnaire (PHQ-2, Kroenke 2003) and Mental Health Inventory (MHI-5, Berwick 1991), and QOL utilizing a single numeric analog scale (range 0-10) regarding overall quality of life. Linear regression analysis was utilized to establish the relationship between individual symptoms and QOL, and a structural equation model (SEM) was used to identify complex relationships among patient demographics, behavioral factors, comorbidities, and QOL. Results: A total of 914 patients from the online survey lived in the USA and provided data for this analysis. Average age was 62 with 67% of patients being female and the mean BMI was 25. Education varied across middle school or high school education (22%), undergraduate or college degree (44%), masters (26%), to doctorate (8%). 43% of respondents were employed. Fatigue (β coefficient 0.23, p<0.001), inactivity (β 0.21, p<0.001), concentration difficulties (β 0.13, p<0.001), sad mood (β 0.18, p<0.001), and night sweats (β 0.05, p=0.03) showed statistically significant impact on QOL. SEM Model: We developed the SEM model in Figure 1. Out of all variables analyzed, MPN total symptom burden demonstrated the strongest association with (β 0.89) with QOL, followed by depression (β 0.76). Comorbidities, including COPD and renal issues, age, and body mass index abnormalities had some impact on symptoms (all β <0.40), but did not demonstrate a significant impact on QOL. Comparative Fit Index (CFI) was 0.905 and root mean square error of approximation (RMSEA) was 0.051 (0.048, 0.054) indicating good fit. Conclusions: Previous clinical trials of JAK inhibition have targeted improvement in symptoms as a key endpoint, and ultimately demonstrated improvements in overall survival. The mechanism of this survival benefit has not been fully explored. This analysis suggests that symptoms and mood are strongly associated and potentially a major contributor to QOL among MPN patients, whereas other major comorbidities and age are not as strongly correlated. Efforts are underway to analyze more comprehensive datasets to better understand the role of other variables, including marriage status and financial concerns, on QOL.

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.

Abstract Introduction: Polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis (MF) are Philadelphia-negative myeloproliferative neoplasms (MPNs) leading to risk of vascular events, splenomegaly and cytopenias in advanced disease as well as disease-originating symptoms, including (but not limited to) fatigue, depressive symptoms, insomnia, inactivity, sexual problems, and pruritis. Current therapy with JAK inhibition has improved MPN symptom burden, yet even in responders, unmet needs remain for alleviating fatigue, mood related symptoms, and insomnia. Yoga used as non-pharmacologic therapy has been shown to be efficacious for improving anxiety, depression, sleep quality, and fatigue in other cancer populations, including hematological malignancies. Due to a lack of this type of research in MPN patients, we undertook the first yoga study in this population as a feasibility trial (i.e., acceptability, demand, practicality) of home-based, online-streamed yoga for improving MPN patient symptom burden. Methods: MPN patients were recruited nationally using social media. Participants were asked to complete 60 minutes of online-streamed yoga weekly for 12 weeks. The yoga video selection included MPN-specific videos as well as others chosen specifically with potential splenomegaly in mind. Additionally, participants were asked to complete online self-report surveys administered via Qualtrics. Survey measures included demographics, total symptom burden and fatigue (MPN Symptom Assessment Form [MPN SAF]) as well as NIH PROMIS measures of pain, anxiety, depression, sleep, and sexual function. Surveys were administered at baseline (week 0), mid-point (week 7), post-intervention (week 12), and follow-up (week 16). Weekly yoga minutes were collected through online self-report. Results:Patients: Two hundred and forty-four MPN patients completed the eligibility survey, 134 were eligible, 55 completed the informed consent, and 38 MPN patients completed the 12-week intervention. The majority of participants were diagnosed with either PV (n=16) or ET (n=16), with MF being less common (n=6). Additionally, the majority of participants were female (n=34), Caucasian (n=37), married (n=30) of a normal BMI category (n=26), and had attained a Bachelor's degree or higher (n=25). Median age of those participating was 56 years (range 29-72). Yoga Participation & Safety:Approximately 37% (n=14) of study participants averaged ≥60 min/week of yoga. Yoga participation averaged 50.8±36.2 min/week. Additionally, 75% of participants felt safe from injury while participating in online yoga. Only one adverse event was reported (irritated enlarged spleen). Feasibility:Overall, 68% of participants were either satisfied or very satisfied with online yoga and 75% felt that is was helpful for coping with MPN-related symptoms (i.e., acceptability, practicality). However, only 43% of participants reported that they were likely or very likely to continue their online yoga practice (i.e., demand). Impact of Yoga Intervention: From baseline (week 0) to post-intervention (week 12, n=30), there were significant improvements in total symptom burden (effect size [ES] in standard deviation units=-0.36, p=0.004), anxiety (ES=-0.67, p=0.002), depression (ES=-0.41, p=0.049), sleep (ES=-0.58, p<0.001), and fatigue (ES=-0.33, p=0.04). These improvements remained significant at follow-up (week 16, n=28) for all outcome measures with a trend for maintained fatigue improvement (ES=-0.34, p=0.06). There were no significant differences in outcomes between those that averaged <60 min/week of yoga compared to those that averaged ≥60 min/week of yoga. Conclusions: A 12-week, home-based, online-streamed yoga intervention is feasible (i.e., accepted, practical) for MPN patients. Although the sample size was small and there was no control group, the results suggest that online yoga may be effective for improving MPN symptom burden, with statistically significant improvements observed in total symptom burden, fatigue, anxiety, depression, and sleep. A randomized, controlled trial is warranted to evaluate home-based, online-streamed yoga on MPN patient outcomes. If effective, yoga may represent a unique non-pharmacologic complement to standard therapies in a population with a heterogeneous symptom profile and significant symptom burden.

Abstract Background: The incidence of multiple myeloma (MM) and enrichment of cytogenetic abnormalities differ significantly between racial/ethnic groups in the US, and their significance in determining myeloma progression and survival is not well understood. Whole genome sequencing has identified unique mutational signatures in MM, including an age-related process common in hyperdiploid myeloma. Our purpose was to describe racial and age-related differences in the impact of high-risk cytogenetic abnormalities (HRCAs) on survival in MM. Methods: We conducted a retrospective cohort study of adult MM patients starting first-line therapy between January 2011 and May 2021 using the nationwide Flatiron Health electronic health record-derived de-identified database. Patient-level demographic and clinical characteristics were ascertained using structured and unstructured data, curated via technology-enabled abstraction. Patients who had documented fluorescence in situ hybridization testing within 30 days prior to or 90 days following the start of first-line treatment were included. HRCAs, including gain or amplification 1q21, deletion 17p, t(4;14), t(14;16) and t(14;20), were identified and categorized as 0, 1, or 2+ HRCAs. Our outcomes of interest were real world progression free survival (rwPFS) and overall survival (rwOS). Cox proportional hazards models were used to calculate adjusted hazard ratios (HR) and 95% confidence intervals (CI), adjusted for demographic and clinical characteristics and treatment including time-dependent receipt of autologous stem cell transplantation. Results: From a cohort of 4889 MM patients, there were 790 (16%) Black and 2995 (61%) White patients with median ages at diagnosis of 68 and 70 years, respectively. Compared to White patients, a higher proportion of Black patients had IgG M-protein (61% vs 55%) and a lower proportion had 1+ HRCAs identified (31% vs 34%). Among all racial groups, compared to patients aged <65 years (N=1771), a higher proportion of patients aged 65+ years (N=3118) had IgA M-protein (21% vs 17%) and 1+ HRCAs identified (35% vs 33%). Multivariable models showed evidence of significant statistical interaction between age and prevalence of HRCA for rwPFS (P-int: 0.02). Among White patients, having 2+ HRCAs ("double-hit MM") compared to no HRCAs was associated with worse rwPFS in both younger and older patients (<65 years: HR 2.88, 95% CI 1.93-4.32, P<0.01; 65+ years: HR 1.51, 95% CI 1.18-1.94, P<0.01). Among Black patients, associations between double-hit MM and rwPFS were attenuated and not statistically significant regardless of age (<65 years: HR 1.81, 95% CI 0.69-4.74, P=0.23; 65+ years: HR 1.61, 95% CI 0.92-2.81, P=0.09). Similarly, we also found evidence of statistical interaction between age and prevalence of HRCA for rwOS (P-int: 0.02). Among White patients, double-hit MM was significantly associated with worse rwOS but the magnitude of increased risk differed for younger (HR 3.39, 95% CI 2.24-5.14, P<0.01) and older (HR 1.61, 95% CI 1.27-2.05, P<0.01) patients. Double-hit MM was significantly associated with worse rwOS among older Black patients (HR 1.78, 95% CI 1.03-3.06, P=0.04), but not younger Black patients (HR 1.60, 95% CI 0.58-4.40, P=0.36). Conclusions: In this cohort of newly diagnosed MM patients treated in routine practice, having double-hit MM was differentially predictive of poor survival across age groups. Double-hit MM was associated with worse rwPFS and rwOS among White patients, but these trends were less consistent among Black patients. Our current understanding of cytogenetic risk stratification of MM requires further study and additional data for identifying low- and high-risk subsets of patients across different ages and racial groups.
