Abstract Background: Therapy for patients (pts) with high risk and/or relapsed or refractory AML remains unsatisfactory. Retrospective studies have demonstrated activity of fludarabine, cytarabine, granulocyte colony stimulating factor and idarubicin (FLAG-IDA) as salvage therapy in pts with relapsed or refractory AML. Furthermore, a recent randomized trial has indicated high complete remission (CR) rates with improved relapsed-free survival when FLAG-IDA is administered as frontline induction chemotherapy (Burnett et al. J Clin Oncol 2013). Therefore, since January 2011, we have employed FLAG-IDA as first line therapy in pts with high risk AML (i.e. poor risk cytogenetics, antecedent myeloproliferative neoplasm or myelodysplastic syndrome, or therapy-related AML), or as first salvage in pts with primary refractory or relapsed AML, in an attempt to improve CR rates and permit more patients with AML to advance to allogeneic hematopoietic stem cell transplantation (alloSCT). Methods: A retrospective review was conducted of the 62 consecutive patients with high risk AML or primary refractory or relapsed AML treated with FLAG-IDA between January 2011 to December 2013 at the Princess Margaret Cancer Centre to determine the CR rate and overall survival (OS) associated with FLAG-IDA remission induction chemotherapy. Results: Baseline characteristics of the patients are listed in Table 1. Fourteen pts received FLAG-IDA as first induction, whereas 48 pts received FLAG-IDA as salvage (39 as first salvage and 9 as second salvage). The overall CR rate (i.e. CR + CR with incomplete platelet recovery [CRi]) using FLAG-IDA as frontline therapy was assessed in 13 patients, as one pt died during induction therapy and therefore, was not evaluable. Of the 13 evaluable patients, all achieved CR or CRi. The overall CR rate for the salvage induction group was 73% (i.e. 31% CR and 42% CRi). The CR duration was censored at time of transplant. The CR duration for pts receiving FLAG-IDA as first induction was 3 mos (range, 0-15 mos). For pts receiving FLAG-IDA as salvage therapy, the CR1 duration for primary refractory AML pts was 6 mos (range, 2-58 mos) and CR2 duration for relapsed AML pts was 4 mos (range, 1-12 mos). 76% of patients (n=10) who received frontline FLAG-IDA induction chemotherapy, and achieved CR/CRi, had a donor identified, but only 40% of those pts underwent alloSCT. 85% of pts (n=30) who received salvage FLAG-IDA, and achieved CR/CRi, had a donor identified, but only 53% of those pts proceeded to alloSCT. The length of hospital stay during the first FLAG-IDA induction was 33 days (range, 17-96 days), whereas the length of hospital stay for salvage FLAG-IDA induction was 43 days (range, 10-305 days). Fourteen percent of pts in the first induction group were admitted to the ICU during their induction, compared to 17% of pts in the salvage induction group. The median ICU stay was 39.5 days and 14 days, respectively. There was a 14% death rate during FLAG-IDA induction for both groups. The median follow up time from diagnosis for both groups was 15.28 mos (range, 2-70.4 mos). Overall survival at 1 and 2 years in the upfront FLAG-IDA induction group was 65% and 41%, respectively, while OS at 1 and 2 years for the salvage FLAG-IDA group was 60% and 35%, respectively. Conclusions: The toxicities associated with FLAG-IDA induction, including induction death rates and ICU admission rates, are acceptable and similar in the untreated and heavily pre-treated groups. FLAG-IDA induction can result in durable CR rates, permitting patients with high risk AML or patients with primary refractory or relapsed AML to proceed to allogeneic transplantation.

BACKGROUND As the COVID-19 pandemic continues, an initial risk-adapted allocation is crucial for managing medical resources and providing intensive care. OBJECTIVE In this study, we aimed to identify factors that predict the overall survival rate for COVID-19 cases and develop a COVID-19 prognosis score (COPS) system based on these factors. In addition, disease severity and the length of hospital stay for patients with COVID-19 were analyzed. METHODS We retrospectively analyzed a nationwide cohort of laboratory-confirmed COVID-19 cases between January and April 2020 in Korea. The cohort was split randomly into a development cohort and a validation cohort with a 2:1 ratio. In the development cohort (n=3729), we tried to identify factors associated with overall survival and develop a scoring system to predict the overall survival rate by using parameters identified by the Cox proportional hazard regression model with bootstrapping methods. In the validation cohort (n=1865), we evaluated the prediction accuracy using the area under the receiver operating characteristic curve. The score of each variable in the COPS system was rounded off following the log-scaled conversion of the adjusted hazard ratio. RESULTS Among the 5594 patients included in this analysis, 234 (4.2%) died after receiving a COVID-19 diagnosis. In the development cohort, six parameters were significantly related to poor overall survival: older age, dementia, chronic renal failure, dyspnea, mental disturbance, and absolute lymphocyte count &lt;1000/mm<sup>3</sup>. The following risk groups were formed: low-risk (score 0-2), intermediate-risk (score 3), high-risk (score 4), and very high-risk (score 5-7) groups. The COPS system yielded an area under the curve value of 0.918 for predicting the 14-day survival rate and 0.896 for predicting the 28-day survival rate in the validation cohort. Using the COPS system, 28-day survival rates were discriminatively estimated at 99.8%, 95.4%, 82.3%, and 55.1% in the low-risk, intermediate-risk, high-risk, and very high-risk groups, respectively, of the total cohort (<i>P</i>&lt;.001). The length of hospital stay and disease severity were directly associated with overall survival (<i>P</i>&lt;.001), and the hospital stay duration was significantly longer among survivors (mean 26.1, SD 10.7 days) than among nonsurvivors (mean 15.6, SD 13.3 days). CONCLUSIONS The newly developed predictive COPS system may assist in making risk-adapted decisions for the allocation of medical resources, including intensive care, during the COVID-19 pandemic.

Abstract Around 50% of patients with high-risk MDS or MDS-AML may enter CR after induction chemotherapy, but CR duration, as well as overall survival is usually short. To address this clinical problem the Nordic MDS Group designed a prospective multicenter phase II study, which assessed the clinical feasibility and utility of long-term maintenance treatment with azaciditine. Sixty patients with high-risk MDS (IPSS intermediate-2 or high) (n=23) or AML following a previous known MDS (n=37) were enrolled between 2004 and 2006. The mean age was 68 (54–83) and patients should not be eligible for stem cell transplantation. Induction treatment consisted of standard doses of daunorubicin and ara-C. Patients in CR received low dose azacitidine subcutaneously 5/28 days until relapse, unless unacceptable toxicity developed. Methylation status of the P15ink4b (P15), E-cadherine (CDH) and Hypermethylated in Cancer 1 (HIC) gene was analysed at study start, in CR and in some patients during follow up. Last follow up was on August 1 2008, 24 months after the last CR was reported. Twenty-four patients (40%) reached CR and 23 of these started maintenance treatment with azacitidine. The initial dose of azacitidine was 75 mg/m2 but as four of the first five enrolled patients developed grade 4 cytopenia, the starting dose was lowered to 60 mg/m2, and was allowed to be reduced to 45 or 30 mg/m2 to avoid severe cytopenias. The mean dose of azacitidine was 54.3 mg/m2. Azacitidine was well tolerated. In 52% of the cases no side effects at all were reported. The most commonly reported side effect was mild rashes at the injection site (35%). Twenty-two percent developed fever or some kind of infection, mostly mild. Myelosuppression (grade 1–3) was seen in 22% of the cases. As previously reported, the probability of reaching CR was negatively correlated to promoter hypermethylation of CDH (p=0.008) and none of the 6 patients hypermethylated on all 3 genes reached CR (p=0.03) and hence only four patients hypermethylated on other genes than P15 received demethylating therapy. The median CR duration for the azacididine treated group was 13.5 months (2–49+) and median survival time from time of inclusion in the study for the same group was 20 months (4–52+). Four of 23 patients (17%) had a CR exceeding 24 months (32–52+). The two patients hypermethylated on CDH pre-induction had CR durations of only 2 and 5 months respectively. By last follow up 3 patients were still in CR. Of 10 patients without any methylation pre-treatment, all but one maintained this pattern in CR. Of the nine patients with pre treatment methylation of at least one gene, only one remained hypermethylated in CR. This patient had a CR duration of only 5 months. One patient showed development of P15 hypermethylation in the bone marrow sampled at 12 months and relapsed at 15 months. These findings support previous reports on P15 hypermethylation as a marker for minimal residual disease (MRD) and threatening relapse. In the whole group, survival was significantly shorter in patients with CDH methylation (3 vs 9 months, p=0.005), while pre-treatment p15 methylation status did not affect CR duration or overall survival. In conclusion, we show for the first time that maintenance treatment with azacytidine is feasible and associated with a median CR duration of 13.5 months, and very mild side effects. However azacytidine does not seem to prevent relapse in the majority of patients, including those with hypermethylation pre-treatment and/or in CR. Hypermethylation of multiple genes is a strong negative factor for survival, probability of CR, and CR duration. We observe a subset of patients, 17%, with a CR duration of &gt;24 months; but no persistent pattern regarding cytogenetics, methylation or morphology could be identified in this group. The strong negative impact of E-Cadherin methylation, a gene involved in adhesion, warrants further investigation.

Abstract Abstract 1294 Background: Patients with AML or MDS who relapse after allogeneic HSCT have a poor prognosis and therapeutic options are limited. The DNA hypomethylating agent Aza has significant activity in patients (pts) with AML and MDS and retrospective analyses have recently shown encouraging results with the use of Aza +/− DLI in patients with AML and MDS, who relapsed after allogeneic HSCT (Czibere et al., 2010; Luebbert et al., 2010). In line with these clinical observations preclinical data suggest that Aza enhances a Graft-versus-Leukemia (GvL) effect while mitigating Graft-versus-Host Disease (GvHD). Design/Methods: To evaluate the activity and safety of Aza in combination with DLI as first salvage therapy in pts with AML or MDS relapsing after HSCT, we conducted a prospective, multicenter, single-arm phase-II trial. Pts were allowed to receive up to 8 cycles Aza (100 mg/m2/d d1-5, every 28 days) and 3 DLI with increasing dosages (1-5×106 – 1–5×108 cells/kg) after every 2nd Aza treatment cycle. Additional DLI were permitted. Results: Between January 2009 and May 2010, 30 pts from 6 German transplant centres were included into this trial. So far, 25 pts (15 female/10 male) were evaluable and are presented in this analysis: Of these, 23 (92%) suffered from AML (15 de novo/8 secondary following MDS), 1(4%) from a MDS (RAEB-1) and 1 (4%) from a myelodysplastic/myeloproliferative syndrome (MDS/MPS, CMML-1). Median age was 54 years (range 29–71). Conditioning was myeloablative in 24 pts (96%) and non-myeloablative in 1 patient (4%). Eight pts (35%) received a graft from a matched sibling donor, while 15 (65%) were transplanted with a matched unrelated donor (2 pts missing data). Peripheral blood stem cells (PBSC) were used in 24 pts (96%; 1 pt missing data). At the time of transplant 6 pts (24%) had primary induction failure, another 6 (24%) suffered from first or secondary relapse, 10 pts (40%) were in first or second complete remission (CR), while 3 pts (12%) were untreated. With regard to their molecular and genetic characteristics at diagnosis, 21 pts belonged to an adverse (9 pts) or intermediate (12 pts) group, whereas 2 pts were diagnosed with a favourable genetic phenotype (2 pts not performed). Prior to relapse 9 (36%) and 3 (12%) pts had episodes of acute GvHD and/or chronic GvHD, respectively. Relapse occurred in all pts after a median of 160 days (range 19–1199) following HSCT (median BM blasts: 34%, range 5–100%, median chimerism: 63% range-1-100%). At the time of relapse, karyotype was evaluable in 13 of 25 pts (52%). Of these 13 pts, 4 pts had a normal karyotype, while 9 had chromosomal aberrations including 6 pts with a complex karyotype. Patients received a median of 3 courses Aza (range 1–8) and 18 of 25 pts (72%) received DLI (median: 1, range: 1–4, median CD3 dose 5×106/kg/DLI, range: 1–207×106). Following treatment, overall response rate was 64% with 5 pts (20%) achieving a CR or CRi, 3 (12%) a partial remission (PR) and 8 (32%) a stable disease (SD). Median response duration was 266 days. Acute GvHD occurred in 6 pts (24%) (2 skin/6 liver/ 2 gut) after a median of 65 days (range 19–179) following the first DLI, while chronic GvHD was observed in 3 pts (12 %, all limited). Hematotoxicity (grade III-IV) was observed in 64% of all evaluated patients. Common adverse events were gastrointestinal side effects as well as infections. After a median follow-up of 100 days (range 25–485) 15 of 25 pts (60%) are currently alive. Median overall survival of all pts is 184 days (range 87–281). All pts, who achieved a CR/CRi, remained in ongoing remission for a median time of 229 days. Achieving a CR (CR: not reached vs. no CR: 117 days, p .008) or any type of response (CR/CRi, PR or SD) to the combination of Aza and DLI (any response: not reached vs. no response: 79 days, p .0001) were associated with a significantly longer overall survival. Conclusion: The combination of Aza and DLI as salvage treatment for patients with AML or MDS who relapse after allogeneic HSCT seems to be safe and shows significant anti-leukemic activity. Response, including CR rates, so far match those from retrospective analyses. Data presented in this interim-analysis suggest that salvage therapy with Aza and DLI is of substantial therapeutic benefit in these challenging patients.

Abstract Abstract 1938 Introduction: Patients with relapsed or primary refractory AML have a dismal prognosis. Even salvage therapy with allogeneic hematopoietic cell transplantation (HCT) could not improve outcome due to high incidence of relapse and high non-relapse mortality (NRM). Recently, promising results in patients with unfavorable karyotype or treatment refractory AML have been reported using a sequential treatment with aplasia inducing chemotherapy consisting of Fludarabine, Ara-C and Amsacrine (FLAMSA) followed within 3 days by reduced intensity conditioning (RIC) for allogeneic HCT (Schmid et al., Blood 2006 Aug 1;108(3):1092–9). Methods: We report a retrospective analysis of our single center experience with FLAMSA-RIC in primary refractory or relapsed AML patients. We searched our database for patients receiving FLAMSA-RIC in the past 10 years. Details on characteristics and clinical course of the patients were confirmed by retrospective chart review. Results: We retrospectively identified and analyzed 51 consecutive patients (f=22, m=29) transplanted after FLAMSA-RIC at our institution from 2006–2011. At time of HCT patients were refractory after chemotherapy (n=22) or had an untreated relapse (n=29). Data on molecular and cytogenetic markers were available in 36 and 44 patients, respectively. 34 were initially high-risk because of unfavorable karyotype (n=25) or molecular genetic alterations (n=9). Median age of patients was 56 years (range, 20–72) and diagnosis of all patients was acute myeloid leukemia (de-novo AML, n=27, secondary AML, n=24). FLAMSA (Fludarabine 30 mg/m2 day −12 to −9, AraC 2000 mg/m2 day −12 to −11 and Amsacrine 100 mg/m2 day −12 to −9) was used as salvage therapy followed by RIC (Fludarabine 30 mg/m2 day −5 to −4/Busulfan 0.8 mg/kg day −6 to −4, n=10; TBI 4Gy on day −5/Cyclophosphamide 60 mg/kg on day −4 to −3, n=28; Busulfan 0.8 mg/kg day −6 to −4/Cyclophosphamide 60 mg/kg for matched and mismatched unrelated donors (MUD/MMUD) or 40 mg/kg for matched related donors (MRD) on day −3 to −2, n=13). As GVHD prophylaxis calcineurin inhibitor combined with mycophenolate mofetil and anti-thymocyte globuline (ATG-Fresenius®, 10 mg/kg for MRD and 20 mg/kg for MUD/MMUD) was used. 10 patients were transplanted from MRD, 16 from MUD, 21 from a MMUD and 4 from a MMRD. 14 patients received DLI (2 × 106 - 1 × 108 /kg after a median of 186 days, range 72–922) in absence of GVHD in case of mixed chimerism or relapse after HCT. Current overall survival (OS) was 18/51 patients with a median follow-up of 410 days (range, 179–1557) of patients alive resulting in a Kaplan-Meier estimated 2-year OS and event-free-survival (EFS) of 34% and 29%, respectively. There was no significant difference between the different RIC regimens with 50% Fludarabine / Busulfan vs. 26% TBI 4Gy / Cyclophosphamide and 40% Fludarabine / Busulfan (p=0.37). Causes of death were relapse (n=19), infections (n=5), GVHD (n=2), multi-organ-failure (n=5), cerebral hemorrhage (n=1) and progressive multifocal leukencephalopathy (n=1). Cumulative incidence of relapse at 2 years with death due to NRM as competing risk was 40% and cumulative incidence at 2 years of NRM with death due to relapse as competing risk was 27%. 2-year OS was inferior in patients with secondary AML compared to patients with de-novo AML (28% vs. 38% p=0.79). The outcome in the elderly subgroup defined by age ≥60 years (median age 67, n=22) was similar to the group of younger patients (median age 46, n=29) with 2-year OS of 31% vs. 37% (p=0.87). Patients with a blast count < 10% in the bone marrow at time of HCT had a better outcome with 64% vs. 25% OS (p=0.09). 2-year-OS was inferior in patients being refractory after chemotherapy (25% vs 38%, p=0.78). Incidence of acute GVHD (aGVHD) ≥II and chronic GVHD (cGVHD, limited, n=11, extensive, n=3) was 22% and 27%, respectively. Presence of aGVHD did not influence survival while presence of cGVHD was associated with an improved overall survival after HCT (58% vs 24%, p=0.009). Conclusion: FLAMSA-RIC followed by allogeneic HCT enables long-term disease free survival, even in primary refractory or relapsed AML patients. The sequential approach of this regimen seems to overcome the dismal prognosis of these patients. Its moderate toxicity allows the application of this curative salvage therapy option even in an elderly patient population. Disclosures: Off Label Use: The use of some agents in the conditioning is off-label.

Abstract Background: Most adults with AML or high-risk MDS will ultimately require salvage therapy. However, the likelihood of achieving a complete remission (CR) with standard salvage regimens is often 15-20% or less. Emerging data suggest that pre-treatment (“priming”) with a hypomethylating agent such as decitabine can sensitize AML cells to chemotherapeutics, prompting a dose-escalation study of MEC preceded by decitabine-priming in relapsed/refractory AML and high-risk MDS. Methods: This single arm study aimed to estimate the maximum tolerated dose (MTD) of decitabine-primed MEC in adults ≥18 years with relapsed/refractory high-risk MDS (>10% blasts) or AML requiring first or subsequent salvage therapy. Previous treatment with hypomethylating agents or MEC (but not the combination) was acceptable. Trial participation required a treatment-related mortality (TRM) score of <9.2, corresponding to an expected TRM of 4% with standard induction chemotherapy. Patients with post-transplant relapse were eligible if graft-versus host disease was well controlled. Excluded were patients with concomitant illness with expected survival <1 year, and active, uncontrolled infection. Cohorts of 6-12 patients were assigned to 1 of 3 total dose levels of decitabine (20mg/m2 for 5, 7, or 10 days) followed by MEC (mitoxantrone 8mg/m2/day x 5 days; etoposide 100 mg/m2/day x 5 days; cytarabine 1 g/m2/day x 5 days) after a break of 5 days. In the case of persistent leukemia, patients were eligible for re-induction provided all non-hematologic toxicities had resolved to grade <2. Patients achieving a CR or CR with incomplete platelet recovery (CRp) could receive 2 additional cycles of decitabine-MEC given at doses identical to those used during induction. Dose-limiting toxicity (DLT) was defined as: 1) any grade 3 non-hematologic toxicity lasting >48 hours that resulted in >7 day delay of the subsequent treatment cycle, with the exception of febrile neutropenia or infection; 2) any grade ≥4 non-hematologic toxicity, with the exception of febrile neutropenia/infection or constitutional symptoms, if recovery to grade ≤2 within 14 days. Results: 30 patients, median age 55 (range: 19-72) years, with primary refractory disease (n=13), first relapse (n=16), or second relapse (n=1) with median duration of prior CR of 4 (range: 1-19) months were enrolled and received a median of 1 (range: 1-3) cycles of therapy. During dose escalation, 1 DLT occurred at each the 2nd and 3rd tested dose level after cycle 1 (septic shock with multi-organ failure in both), identifying a 10-day course of decitabine together with standard dose MEC as the MTD. A total of 12 patients received therapy at the MTD level. 9/30 patients achieved a CR (30%). This CR rate compared favorably relative to a historic control population with patient matching based on duration of prior remission and number of prior salvage therapies (Blood 1996; 88:756), with an observed/expected CR ratio of 1.9. 5 additional patients achieved a CRp, and 1 achieved a CR with incomplete count recovery (CRi) for an overall response rate of 15/30 (50%). Furthermore, 4 patients achieved a morphologic leukemia-free state, 8 had refractory disease, and 3 died before a response was assessed. Of the 15 patients who achieved a remission, 3 remain on study, 9 were taken off protocol to pursue further intensive consolidation therapy including hematopoietic cell transplantation, and 3 have died after a median CR duration of 68 days. In the 15 responders, the median response duration was 68 days (range 0-437), with 6 of these responses ongoing. Overall survival of these 15 patients was longer (median of 211 [range: 59-484] days) than that for patients who failed to achieve remission but lived at least 29 days (i.e. did not experience TRM) (median of 110 [range: 30-303] days). Six patients died within 28 days of treatment initiation for a TRM rate of 20%: 4 from infection, 1 from intracranial hemorrhage, and 1 from unknown cause. Besides grade 3-4 cytopenias, cough, fatigue, nausea and infection/neutropenic fever were the most common adverse events. Conclusion: Decitabine-primed MEC is feasible, well tolerated, and has anti-leukemic activity in relapsed/refractory AML and high-risk MDS. A phase 2 study based on these findings has been initiated. Disclosures Off Label Use: Off-label use of some of the study drugs for either AML or high-risk MDS.

Objective Impella 2.5 has been shown to reduce major adverse events for patients undergoing elective high-risk percutaneous coronary intervention. We performed a single-center retrospective study to compare the costs and resource use of Impella 2.5 and intra-aortic balloon pump (IABP) support. Methods All high-risk patients who received Impella 2.5 (n = 35) and IABP (n = 295) support from December 2008 to July 2011 were included. Propensity score matching identified a balanced 1:1 matched cohort (35 Impella vs 35 IABP) based on indications for implantation, preimplantation hemodynamics, and age. Diagnostic, procedural, financial, and resource use data were collected. Results As compared with IABP, Impella offered a more predictable course of treatment/resource consumption and was not associated with any extreme cost outliers (17.1% vs 0.0%, respectively; P = 0.025). The mean admission and 90-day episode of care total costs for Impella were 5.5% ($67,681 vs $71,608, P = 0.79) and 4.2% ($70,680 vs $73,476, P = 0.85) lesser than that for IABP, respectively. Although not statistically significant, Impella patients had a trend toward lower rehospitalization rates (11.4% vs 20%), lesser mean index length of hospital stay (11.2 vs 13.7), and 90-day (11.7 vs 14.2) episode of care length of hospital stay. Conclusions Impella support was associated with consistent course of treatment/resource consumption with significantly fewer 90-day extreme cost outliers than was IABP. The lower index and 90-day follow-up cost trends observed for Impella were driven by shorter length of hospital stay and fewer rehospitalizations. As providers strive to improve quality of care by reducing variability, these findings have implications for the development of hemodynamic support algorithms.
