Abstract: Febrile neutropenia (FN) is an oncologic emergency, and prolonged time to antibiotic administration (TTA) is associated with increased hospital length of stay (LOS) and worse outcomes. We hypothesized that a febrile neutropenia pathway (FNP) quality initiative project would reduce TTA delays for febrile patients with cancer presenting to the emergency department (ED). Methods: This prospective study compared ED FNP patients ( 〉 18 years old), between June 2012 and June 2013 with both historical and direct admissions (DA) cohorts at a multispecialty academic center. Interventions included providing patients with FN-Alert cards, standardizing the definition of FN and recognizing it as a distinct chief complaint, revising ED triage level for FN, creating electronic FN order sets, administering empiric antibiotics before neutrophil count result, and relocating FN antibiotics to the ED. The primary outcome was TTA, with a target goal of 90 minutes after ED presentation. Results: In total, 276 FN episodes in 223 FNP patients occurred over the 12-month study period and were compared with 107 episodes in 87 patients and 114 episodes in 101 patients in the historical and DA cohorts, respectively. Use of the FNP reduced TTA from 235 and 169 minutes in historical and DA cohorts, respectively, to 81 minutes, and from 96 to 68 minutes when the order set was not used versus used in the FNP group (P 〈 .001 for all comparisons). Decrease in hospital LOS was not statistically significant. Conclusion: The ED FNP is a significant quality initiative with sustainable interventions, and was able to demonstrate value by decreasing TTA compared to both historical and DA controls in cancer patients presenting to the ED.

Abstract: Febrile neutropenia (FN) is an oncologic emergency associated with high morbidity and mortality, particularly in patients (pts) with hematologic malignancies. Delays in antibiotic administration, which can occur in busy emergency departments (EDs), lead to worse outcomes. We instituted a FN pathway (FNP) in the Cleveland Clinic (CC) ED to reduce antibiotic delays. Methods This prospective study comparing patients from 06/12 - 06/13 to historical pts from 02/10 - 05/12, represented a collaboration among cancer center, ED, infectious disease, pharmacy, and electronic medical record representatives. Fever was defined as temperature 〉 38°C either at home or in the ED, while neutropenia as absolute neutrophil count 〈 0.5 x 109/L. All CC cancer pts received a special “Neutropenic Risk Hospital Medical Alert Card,” which they presented upon CC ED registration with fever. The pathway formally recognized “fever with a history of cancer” to be a distinct chief complaint and FN to be categorized as Emergency Severity Index level 2 (equivalent to stroke or myocardial infarction) for immediate triage and care. ED-specific electronic FN order sets were created to facilitate antibiotic, laboratory, and blood culture ordering, with antibiotics administered prior to return of neutrophil count. The primary goal of the FNP is administration of empiric broad-spectrum antibiotics within 120 minutes of ED presentation, per Infectious Diseases Society of America guidelines; and the primary outcomes measured were time intervals related to it, e.g. time to blood draw, physician assessment, and antibiotic order/administration. Group comparisons were made using the chi-square, Kruskal-Wallis, Wilcoxon rank-sum, and log rank tests, as appropriate. All reported times were from ED registration. Results In total, 137 consecutive FN episodes in 115 pts with hematologic malignancies occurred during the 12 month study period, 63 episodes in 44 pts in the historical cohort. All pts were triaged and treated using the ED FNP, but use of the specific FN order set was variable: episodes were thus classified as treated per the order set (n=53) or not (n=84 – pts still received antibiotics, but not necessarily per the order set). Overall 60% of pts (n=89) were male and the median age at the time of first ED encounter was 59 years (range 20-88). Cancers were: non-Hodgkin lymphoma (38%), acute myeloid leukemia (21%), other leukemias (15%), and myelodysplastic syndromes (8%). Compared to historical pts, FNP study pts had a higher median ANC (2.0 vs. 0.2, p 〈 0.0001), were less likely to be on growth factors (26% vs. 41%, p=0.06) and more likely to have received prophylactic antibiotics (55% vs. 35%, p=0.006). For the outcome of interest, FNP study pts had significantly shorter time to having blood drawn (median 38.5 vs. 70 minutes, p 〈 0.0001), seeing a doctor (median 44 vs. 71 minutes, p=0.0002) and to receiving antibiotics (median 79 vs. 228 minutes, p 〈 0.0001). Time to admission was also shorter for FNP study pts (4.2 vs. 6.0 hours, p 〈 0.0001), though study pts were less likely to be admitted than historical controls (83% vs. 97%, p=0.005). For FNP pts admitted to the hospital, there was a non-significant decrease in length of stay (median 3.8 vs 4.6 days, p=0.28), ICU admission (7% versus 11%, p=0.26), and length of ICU stay (median 1.9 vs 2.3 days, p=0.83) compared to historical controls. Comparing the two FNP groups treated or not treated per the order set, those treated using the order set had shorter times to antibiotics being ordered (median 28.0 vs. 60.5 minutes, p 〈 0.0001) and administered (median 66.0 vs 92.5 minutes, p=0.002). ED order set pts also had a higher rate of antibiotic use (100% vs 90%, p=0.02). Correct antibiotic use, antibiotic over-use, hospital and ICU admission rates, time to hospital admission, and length of hospital stay were all similar between the two groups (all p 〉 0.28). Conclusion The FNP significantly decreased time from ED registration to all set time-points, including time to antibiotics by almost three-fold, compared to historical controls in pts with hematologic malignancies. Rate of hospitalization was significantly lower, and ICU and length of stay numerically lower. The FNP is an effective clinical tool to provide prompt antibiotic administration to FN pts and likely represents a significant mechanism for improved outcomes and cost-savings to patients with hematologic malignancies presenting with FN.

Abstract: Background: Adult acute myeloid leukemia (AML) patients with high-risk cytogenetics have a significantly worse survival compared to similarly treated intermediate- or favorable-risk patients. Although prior studies suggest better outcome in high-risk AML patients in first complete remission (CR1) who undergo allogeneic hematopoietic cell transplantation (HCT) compared with consolidation chemotherapy, only 40% of patients proceed to HCT. The lack of a matched sibling donor (available in about 33%) should not be a barrier to HCT since alternative donors are available for the large majority of high-risk AMLpatients and recent data suggest outcomes after allogeneic HCT from fully matched unrelated donors are similar to those following matched related donor transplantation. We sought to determine if a prospective organized effort could rapidly identify alternative donors to improve the historical 40% allogeneic HCT rate in high-risk CR1 AML patients ≤ age 61. Secondly, we hypothesized that transplanting significantly more adults with high-risk AML in CR1 would lead to an improved outcome compared with the historical relapse-free survival (RFS) of 22%. Patients and Methods: Adult patients between ages 18 and 60 years with untreated AML were randomized to receive induction therapy with standard cytarabine plus daunorubicin (7+3; n=261), idarubicin with high-dose cytarabine (IA; n=261), or IA with vorinostat (IA+V; n=216). Conventional cytogenetics were obtained at time of enrollment and used to determine risk classification by standard criteria. All patients with high-risk cytogenetics underwent expedited HLA-typing. High-risk patientswere encouraged tobe referred for consultation with a transplant team with the goal of conducting an allogeneic HCT in CR1. Results: Of 738 eligible patients (median age, 49 years; range, 18-60), 159 (22%) had high-risk cytogenetics, of whom 60 (38%), 61 (38%), and 38 (24%) received induction with 7+3, IA, or IA+V, respectively. A total of 107 of the 159 high-risk patients achieved CR/CRi (67%). HCT was performed in 317 of all 738 patients (43%) and 68 (64%) of the high-risk patients received a transplant in CR1 (p 〈 0.001 compared to historical rate of 40%). Twenty-five (37%) had a matched related donor, 31 (45%) had a matched unrelated donor, 3 (4%) had a mismatched related donor, 8 (12%) had a mismatched unrelated donor, and 1 (1%) received an umbilical cord blood transplant. Sixty-six high-risk patients transplanted in CR/CRi have detailed data. Median time to HCT from CR1 was 76 days (range, 20-365). Fifty-seven patients (86%) received a myeloablative regimen and 9 (14%) reduced-intensity conditioning. Reasons for 39 high-risk CR1 patients not receiving a transplant in CR1 were: co-morbidities (n=1), death (n=6), no insurance (n=1), no donor (n=1), physician decision (n=3), patient decision (n=3), relapse (n=6), other (n=10), or unknown (n=8). The 2-year RFS estimate in the entire high-risk cohort is 32%, significantly higher than the 22% historical rate (p=0.05). Median RFS in the high-risk CR1 cohort (n=107) was 10 months [range, 1-32* (censored) months]. RFS and OS were similar among HCT patients using matched related [1 year estimates: 40% (95% CI 27%, 74%) and 56% (37%, 74%), respectively] and matched unrelated [1 year estimates: 52% (37%, 75%) and 56% (37%, 74%), respectively] donors in CR1. The HR (reference = unrelated) for RFS was 0.67 (0.32, 1.37) and for OS was 0.88 (0.41, 1.90). Median overall survival (OS) among all patients in the high-risk cohort (n=159) was 12 months [range, 1-33* (censored) months] and was 18 months [range 3-33* (censored) months] for those transplanted in CR1 (Fig. 1). Conclusions: In newly diagnosed adults with AML age 18-60, early cytogenetic testing with an organized effort to identify a suitable allogeneic HCT donorled to a CR1 transplant rate of 64% in the high-risk group, which in turn led to a significant improvement in RFS over historical controls. Better outcomes in poor prognosis AML patients may be achieved simply by rapidly finding unrelated donors and performing allogeneic HCT in CR1 as soon as possible.

Abstract: Background: A majority of younger pts with AML receive initial therapy with a 7+3 scheme. Escalated doses of daunorubicin (dauno) in combination with standard doses of ara-C may lead to improved outcomes (Fernandez; NEJM 2009). A phase II trial of idarubicin and high-dose ara-C (IA) in combination with the histone deacetylase inhibitor vorinostat (IA+V) resulted in historically high response rates compared to IA or 7+3 (Garcia-Manero; JCO 2011). SWOG 1203 tested whether a high-dose ara-C induction with or without vorinostat could result in improved outcomes for younger AML pts compared to 7+3. Methods: The primary endpoints were comparison of event-free survival (EFS) of 7+3 vs IA vs IA+V and evaluating the frequency of allogeneic hematopoietic cell transplantation. Secondary endpoints included toxicity, remission rate, relapse-free survival (RFS), and overall survival (OS) according to treatment arm, and by cytogenetic and molecular subgroups. Because of the historical trend of cured pts in S0106, EFS was modeled with an exponential cure model, and it was assumed IA or IA+vorinostat increased the proportion of pts cured from 35% to 45% and increased median EFS among those not cured from 4.7 months to 7.1 months. Main inclusion criteria included a diagnosis of previously untreated non-APL AML by WHO criteria, age 15 to 60 years, and preserved cardiac function but no severe comorbidities. Pts with known CBF rearranged or FLT3 mutant leukemias were eligible if no other alternative clinical trials existed. Treatment was as follows: Induction: 7+3 arm: dauno 90 mg/m2 IV QD x 3 on days 1-3 with ara-C CI 100 mg/m2 QD x 7 days on days 1 to 7. IA arm: ida 12 mg/m2 QD x 3 on days 1 to 3 with 24 hours CI ara-C 1.5 gm/m2 QD for 4 days on days 1 to 4. IA+vorinostat was as IA but with vorinostat 500 mg orally TID for 3 days on days 1 to 3. Consolidation: 7+3 arm: standard high-dose ara-c at 3 gm/m2 over 3 hrs q12 hours x 6 doses for 1 to 4 cycles depending on transplant availability. IA arm: idarubicin 8 mg/m2 IV QD x 2 days on days 1 to 2 with ara-C 0.75 gm/m2 CI for 3 days on days 1 to 3 for 4 cycles. The number of consolidation cycles depended on transplant indication; a secondary aim of the study was to transplant all cytogenetically-determined high risk pts (presented in a different abstract). Results: Of 754 pts randomized, 738 were eligible (261 to 7+3, 261 to IA, and 216 to IA+V). Baseline characteristics were well balanced among all three groups. Most (75%) pts were between 40 and 60 years, 51% were male, median (range) WBC and platelets were 10.8 (0.3-800) and 49 (3-3900), respectively; marrow blast percentage was 60% (0%-100%); cytogenetics were favorable in 13% of pts, intermediate in 63%, and high-risk in 22%; FLT-3 was mutated in 21% and unknown in 31%; NPM1 was mutated in 20% and was unknown in 37%. Complete remission (CR) rates were 75% for 7+3, 79% for IA, and 77% for IA+V (p=0.58). Significantly more pts received reinduction with 7+3 (24%) versus 11% with IA and 9% with IA+V (p=0.001). 48% of intermediate and unfavorable risk pts received transplant in CR1, with no significant differences among arms (p=0.44). There were no significant differences in EFS, RFS or OS among all three arms (Figure 1, all p 〉 0.5). By cytogenetic or molecular group, there were no differences in outcome for any standard risk subset (FLT-3, NPM1, or CEBPα or cytogenetic subset), although pts with favorable cytogenetics had significantly better EFS, RFS and OS with 7+3 therapy compared to IA or IA+V (Figure 2, all p≤0.015). 30% of pts received 1 consolidation cycle, 18% 2, 16% 3, and 37% 4 cycles. Grade 5 induction toxicity rates were 4% (7+3), 8% (IA), and 9% (IA+V) by arm (p=0.07), and for toxicities related to therapy, 2%, 7%, 8%, respectively (p=0.01). Grade 4 induction toxicity rates were similar across arms (p=0.38). Conclusion: Treatment with IA is not more effective than 7+3 in younger pts with AML. Outcomes with IA or IA plus vorinostat are similar. In pts with favorable cytogenetics, outcomes were inferior with IA or IA+V when compared to 7+3, perhaps related to use of lower doses of ara-C during consolidation.

Abstract: Glasdegib is a Hedgehog pathway inhibitor. This ongoing, open‐label, phase 2 study (NCT01546038) evaluated glasdegib plus cytarabine/daunorubicin in patients with untreated acute myeloid leukemia (AML) or high‐risk myelodysplastic syndromes (MDS). Patients received glasdegib 100 mg orally, once daily in continuous 28‐day cycles from day −3, with intravenous cytarabine 100 mg/m 2 on days 1‐7 and daunorubicin 60 mg/m 2 on days 1‐3. Patients in remission then received consolidation therapy (2‐4 cycles of cytarabine 1 g/m 2 twice daily on days 1, 3, 5 of each cycle), followed by maintenance glasdegib (maximum 6 cycles). Primary endpoint was complete remission (CR) in patients aged ≥55 years. Secondary endpoints included overall survival (OS), safety and outcome by mutational status. Patients had a median (range) age of 64.0 (27‐75) years, 60.0% were male, and 84.5% were white. In 69 evaluable patients, 46.4% (80% confidence interval [CI]: 38.7‐54.1) achieved investigator‐reported CR. Among patients ≥55 years old ( n = 60), 40.0% (80% CI 31.9‐48.1) achieved CR. Among all 69 patients, median OS was 14.9 (80% CI 13.4‐19.3) months, with 12‐month survival probability 66.6% (80% CI 58.5‐73.4). The most common treatment‐related adverse events (≥50% patients) were diarrhea and nausea. There were no significant associations between mutational status (12 genes) and clinical response, suggesting potential benefit across diverse molecular profiles. Glasdegib plus cytarabine/daunorubicin was well tolerated and associated with clinical activity in patients with untreated AML or high‐risk MDS. A randomized phase 3 trial of glasdegib in combination with chemotherapy (7 + 3 schedule) is ongoing.

Abstract: The 2016 revision of the World Health Organization classification of tumors of hematopoietic and lymphoid tissues is characterized by a closer integration of morphology and molecular genetics. Notwithstanding, the myelodysplastic syndrome (MDS) with isolated del(5q) remains so far the only MDS subtype defined by a genetic abnormality. Approximately half of MDS patients carry somatic mutations in spliceosome genes, with SF3B1 being the most commonly mutated one. SF3B1 mutation identifies a condition characterized by ring sideroblasts (RS), ineffective erythropoiesis, and indolent clinical course. A large body of evidence supports recognition of SF3B1-mutant MDS as a distinct nosologic entity. To further validate this notion, we interrogated the data set of the International Working Group for the Prognosis of MDS (IWG-PM). Based on the findings of our analyses, we propose the following diagnostic criteria for SF3B1-mutant MDS: (1) cytopenia as defined by standard hematologic values, (2) somatic SF3B1 mutation, (3) morphologic dysplasia (with or without RS), and (4) bone marrow blasts & lt;5% and peripheral blood blasts & lt;1%. Selected concomitant genetic lesions represent exclusion criteria for the proposed entity. In patients with clonal cytopenia of undetermined significance, SF3B1 mutation is almost invariably associated with subsequent development of overt MDS with RS, suggesting that this genetic lesion might provide presumptive evidence of MDS in the setting of persistent unexplained cytopenia. Diagnosis of SF3B1-mutant MDS has considerable clinical implications in terms of risk stratification and therapeutic decision making. In fact, this condition has a relatively good prognosis and may respond to luspatercept with abolishment of the transfusion requirement.
