Description: Background: Understanding health-related quality of life (HRQOL) profile, including functional aspects and symptom burden, of yet untreated patients with myelodysplastic syndromes (MDS) is important to help clinicians to better identify subgroup of patients in need of special attention from the very beginning of therapy. Aims: The primary objective of this study was to investigate baseline (i.e., pretreatment) HRQOL profile of untreated patients with lower-risk MDS, examining differences by age, gender, risk score category and comorbidity. A secondary objective was to provide age and sex baseline reference HRQOL values, according to the EORTC QLQ-C30 questionnaire, to be used as benchmark comparisons in future MDS studies. Methods: This analysis is based on 443 newly diagnosed adult MDS patients with International Prognostic Scoring System (IPSS) risk score of low (46 %) or intermediate-1 (54%), enrolled in an international prospective cohort observational study. Median age was 75 years (range 32-94), with 261 men (59%) and 182 (41%) women. HRQOL was assessed by the EORTC QLQ-C30 questionnaire at study entry, before any treatment (except for transfusions). This well validated questionnaire consists of five functioning scales: physical, role, emotional, cognitive and social; three symptom scales: fatigue, nausea/ vomiting and pain; six single item scales: dyspnoea, sleep disturbance, appetite loss, constipation, diarrhea and financial impact; and the global health status/HRQOL scale. The items were scaled and scored using the recommended EORTC procedures. At the time of baseline HRQOL assessment, 111 (25%) patients had received at least one red blood cell transfusion. We used Wilcoxon-Mann-Whitney and Kruskal-Wallis tests for all comparisons. We used the false discovery rate approach to account for multiple testing, with a nominal α-level=0.05. In addition to statistical significance, clinically relevant HRQOL differences were also evaluated based on previously published criteria (Cocks K, et al, J Clin Oncol 29:89-96, 2011). Results: There were not statistically significant differences in any of the HRQOL scales measured by the EORTC QLQ-C30, by the specific IPSS risk category (i.e., low risk vs intermediate-1 risk score). Overall, women reported worse HRQOL scores than men, with clinically relevant differences for physical (Δ=-7.1, P=0.002), role (Δ=-9.9, P=0.002) and emotional functioning, (Δ=-10, P

Description: Background: About 10% of low risk patients with myelodysplastic syndromes (MDS) experience severe thrombocytopenia. Bleeding and the scarce efficacy of platelet (PLT) transfusions drive research in novel treatments. Eltrombopag is an oral agonist of the thrombopoetin-receptor (TPO-R). Its potential in increasing platelet (PLT) counts in low risk MDS has not been evaluated. We present interim results on the efficacy and safety of eltrombopag in inducing PLT responses in patients with low and intermediate-1 International Prognostic Scoring System (IPSS) risk MDS with severe thrombocytopenia in a Phase II, multicentre, prospective, placebo-controlled, single-blind study (EQoL-MDS). Methods: Primary endpoints are safety and efficacy of eltrombopag. Secondary endpoints include changes in quality of life (QoL), PLT transfusion requirement, incidence and severity of bleeding, and survival. Inclusion criteria are adult age; PLT200 Gi/L or adverse events. Study design is shown in the figure. PLT response, assessed at each visit, is defined as Response if: 1) baseline PLT〉20 Gi/L: absence of bleeding and increase by at least 30 Gi/L from baseline; 2) baseline PLT20 Gi/L and increase by at least 100%, not due to PLT transfusions; and Complete Response if PLT≥100 Gi/L and absence of bleeding. QoL scores are analysed by MDS-specific instrument, QOL-E v. 3. Results: Seventy patients (46 on eltrombopag - Arm A, 24 on placebo -Arm B) have been randomized at the time of this report. Mean age is 68.3 (SD 13.0) years, M/F 38/32. ECOG performance status was 0 in 47 cases, 1 in 16 cases, 2 in 7 cases. Ten patients had comorbidities. According to the WHO 2008 classification, 22 patients had refractory cytopenia with unilineage dysplasia, 9 had refractory anemia with ringed sideroblasts, 31 had refractory cytopenia with multilineage dysplasia (of which 15 with ringed sideroblasts), 6 had refractory anemia with excess blasts-1 and 2 were unclassified. IPSS score was low in 48 cases. Mean baseline platelet (PLT) count was 17.1 (SD 8.2) Gi/L, mean hemoglobin level 10.8 (SD 2.5) g/dL and mean white blood cell count was 5.0 (SD 3.8) Gi/L. Twenty-five (36%) patients were red blood cell transfusion-dependent. Thirty-three had a WHO bleeding scale of 1, 2 experienced mild blood loss, 4 a gross blood loss and 1 a debilitating blood loss. Fourteen patients in Arm A and 8 in Arm B had required PLT transfusions in the 8 weeks prior to randomization. Twenty-three cases (50%) in Arm A have responded versus 2 (8%) in Arm B (p=0.001). Thirty-three patients have completed at least 24 weeks of study. Median time to response was 14 days (IQR 7-46 days) at a median daily dose of 75 (IQR 50-162.5 mg). PLT count increased by mean 53.2 (SD 68.1) Gi/L (p=0.001) in Arm A versus no significant changes in Arm B by week 24. QOL-E scores at baseline and 12 weeks in 47 cases in both arms are shown in the table. There was an increase in treatment outcome index,mainly experienced in the first 3 weeks (p=0.034). Fatigue improved from baseline to 12 weeks associated with response (p=0.016). Related Grade III-IV adverse events (AE) occurred in 10 patients (22%) in Arm A and consisted in: nausea (4), hypertransaminasemia (3), hyperbilirubinemia (1), sepsis (1), pruritis (1), heart failure (1), asthenia (1), vomit (1), while in Arm B 1 patient (4 %) experienced grade 3 bone marrow fibrosis. MDS disease progression occurred in 5 (11%) in Arm A versus 2 (8%) in Arm B, p=ns. Conclusions: Preliminary data indicate that lower risk MDS patients with severe thrombocytopenia undergoing treatment with eltrombopag experience significant improvements in PLT counts accompanied by improvements in fatigue. The drug appears to be well-tolerated and not associated with MDS progression. Further follow-up is required to evaluate the impact on survival. Figure 1. Study design Figure 1.

Description: Background: In myelodysplastic syndromes (MDS), thrombocytopenia is associated with mortality and treatments in this setting are scarce. We tested whether eltrombopag, a thrombopoietin receptor agonist, be effective in improving outcomes in lower-risk MDS with severe thrombocytopenia within a multicentre clinical trial (EQoL-MDS). Initial interim results of short-term efficacy and safety have been published (Oliva et al. Lancet Hem 2017) in the first 90 subjects. We present interim results of the second phase for long-term results in the initial 90 of 174 subjects. Methods: In a single-blind, randomised, controlled, phase 2 trial of adult patients with International Prognostic Scoring System (IPSS) low- or intermediate-1-risk MDS and severe thrombocytopenia. Adult patients with a stable platelet (PLT) count 2% blasts (i.e. the median value of the whole study cohort) tended to be higher (P=0.06) in Eltrombopag (59.3%) than in placebo treated (38.7%) patients and resulted to be a strong predictor of study outcomes at both 2 and 5 years (P
