Although venetoclax (VEN)-based combination chemotherapy in patients with acute myeloid leukemia (AML) results in prolonged and profound neutropenia, data regarding infectious complications and antimicrobial prophylaxis are lacking. We investigated the infectious complications in 122 adult patients with AML under the same standard of care for prevention. The prophylaxis protocol was fluconazole 400 mg/d without antibacterial agents. The incidence of proven or probable invasive fungal infections (IFIs) was 6.6/100 cycles, and 22 patients (18.0%) were diagnosed (median, second cycle; interquartile range, 1–2). All IFIs were caused by Aspergillus and significantly influenced the overall mortality (odds ratio (OR), 2.737; 95% confidence interval (CI), 1.051–7.128; p = 0.034). In the multivariate analysis, secondary or therapy-related AML was an independent risk factor for IFIs (OR, 3.859; 95% CI, 1.344–11.048, p = 0.012). A total of 39 bloodstream infection (BSIs) episodes occurred in 35 patients (28.7%), with an incidence of 12.7/100 cycles. High-dose steroid administration within 90 days was associated with the occurrence of BSIs (OR, 7.474; 95% CI; 1.661–3.631, p = 0.008), although BSIs themselves did not have an impact on the outcomes. Our findings suggest evidence for the need for mold-active antifungal agents as antifungal prophylaxis, rather than fluconazole, especially in patients with secondary or therapy-related AML.

Abstract Background Acute myeloid leukemia (AML) is associated with poor prognosis, particularly in elderly patients with co-morbidities. Low-intensity therapies like azacitidine (aza) were the standard of care and were associated with low response rates and limited survival. Combining venetoclax (ven) with aza demonstrated significant improvements in responses and survival compared to aza alone, and represents the new standard of care for this population. However, as a myelosuppressive regimen, infectious complications, especially invasive fungal infections (IFI), are a potential concern. The incidence of IFI and the role for antifungal prophylaxis have not been well defined for newly-diagnosed AML patients receiving ven/aza. Methods We conducted a retrospective cohort review of AML patients treated with ven/aza at the University of Colorado Hospital from January 2014 to August 2020. Duration of therapy was defined as the time from initiation of treatment through one of the following endpoints (1) patient discontinuation, (2) progression of disease, (3) bone marrow transplantation, or (4) death. Four patients with a history of prior IFI were excluded. We assessed the impact of patient age, sex, duration of neutropenia, antifungal prophylaxis, and AML specific risk factors on the incidence of IFI as defined by the European Mycoses Study Group. Results One hundred forty-four AML patients were included in the study. Ten patients received antifungal prophylaxis and none developed IFI (p=0.21). Twenty-five (17%) patients developed IFI: 2 (8%) had proven IFI, 6 (24%) probable IFI, and 17 (68%) possible IFI. Invasive pulmonary aspergillosis represented all 25 cases of proven, probable, and possible IFI. There was a statistically significant association between prolonged neutropenia ( >60 days) and IFI (p=0.007), whereas age, sex, and SWOG classification were not significantly associated with IFI. Conclusion The incidence of IFI in our AML cohorts treated with ven/aza was 17%, lower than that reported at other institutions. Neutropenia > 60 days was significantly associated with IFI in our AML cohort treated with ven/aza. Although we were not powered to determine whether antifungal prophylaxis impacted IFI, there was no significant difference in IFI for patients who received prophylaxis.

Background and Purpose:Children with acute myeloid leukemia and relapses of leukemia are at high risk of developing fungal infections and need antifungal prophylaxis. This study aimed to compare the efficacy and toxicity of two different dosage regimens of voriconazole (VRCZ) during prophylactic administration in children with malignancyand neutropenia. Materials and Methods:This prospective study was conducted at the Belarusian Research Center for Pediatric Oncology, Hematology, and Immunology fromMay 2017 to December 2019. The present study included 21 Caucasian patients with malignant hematological diseases (20 patients with acute myeloid leukemia and relapses of leukemia and 1 patient with Non-Hodgkin's lymphoma) aged 2-18 years. All patients were randomly divided into two groups that received different dosage regimens of VRCZ prophylaxis. Patients in the “high-dose” group received VRCZat a dose of 9 mg/kg twice a day PO, or 8 mg/kg twice a day IV without a loading dose (children of 2-11 and adolescents and of 12-14 years old with. Results:In the high-dosegroup (n=20 episodes of prophylaxis), invasive fungal infections (IFI) signs were recorded in one (5%) case. In the low-dose group (n=20 episodes), IFI signs were observed in six (30%) cases (P=0.0375). The residual serum concentration was significantly higher in patients who received high doses of VRCZ (p <0.0001). Most patients with IFI (n=6, 86%) had a mean value (i.e.,) Conclusion:The likelihood of IFI was significantly lower in children who prophylactically received VRCZ in high doses (P=0.0375) and had ≥ 0.74 μg/ml residual serum concentration of the medication (P=0.0258). Residual serum concentration of VRCZ reached a plateau by day sixth of the treatment. In children, the dosage was the only highly significant factor affecting the metabolism of VRCZ.

Abstract In recent years, research in molecular genetics has been instrumental in deciphering the molecular heterogeneity of acute myeloid leukemia (AML), in particular the subset of patients with “intermediate-risk” cytogenetics. However, at present, only the markers NPM1, CEBPA, and FLT3 have entered clinical practice. Treatment of intermediate-risk AML patients eligible for intensive therapy has not changed substantially. The “3 + 7” induction therapy still represents the standard of care. The addition of the immunoconjugate gemtuzumab ozogamicin to therapy has been shown to improve outcome; however, the drug is not approved for this use. A common standard for postremission therapy is the administration of repeated cycles of intermediate- to high-dose cytarabine. Allogeneic stem cell transplantation may offer a survival benefit for many patients with intermediate-risk AML. Patients are best selected based on the genetic profile of the leukemia cells and the risk associated with the transplantation itself. A myriad of novel agents targeting mutant leukemia drivers or deregulated pathways are in clinical development. In the past, many novel compounds have not met expectations; nonetheless, with the rapid developments in comprehensive molecular profiling and new drug design, there is the prospect of personalizing therapy and improving patient outcome.

Abstract The most effective reinduction regimen for acute myeloid leukemia (AML) patients who do not achieve complete remission (CR) after one cycle of cytarabine combined with an anthracycline is not well established. In an effort to search for new synergistic and non-cross resistant antileukemic regimens different chemotherapeutic combinations have been investigated in refractory AML patients. Multiple regimens including high dose cytarabine, anthracyclines, fludarabine and etoposide have been used with CR rates up to 40%. Mitoxantrone and etoposide have activity in AML as induction agents but their role in reinduction in patients not responding to first line therapy has not been fully established. In the current retrospective study we evaluated the efficacy and toxicity of mitoxantrone and etoposide in AML patients treated at our institution who did not respond to first induction therapy with cytarabine and an anthracycline. A total of fifty seven AML patients were treated with mitoxantrone and etoposide (mean age 55 years, range 18–75 years). Twenty four patients were treated with mitoxantrone 10 mg/m2/d and etoposide 100 mg/m2/d both administered intravenously, days 1 to 5 (regimen 5+5) and thirty three patients were treated with mitoxantrone 10 mg/m2/d administered intravenously days 1 to 3 and etoposide 100 mg/m2/d administered intravenously, days 1 to 5 (regimen 3+5). Twenty six of fifty seven patients (46%) achieved CR. CR was achieved in 38% of patients (9/24) treated with the 5+5 regimen and 52% of patients (17/33) treated with the 3+5 regimen. Mean blast percentage before treatment with mitoxantrone and etoposide was 25% in patients who achieved CR vs 40% in patients who did not achieve CR (p < 0.03). Grade 3/4 hepatic toxicities were seen in 5% (3/57) of patients and there were no grade 3 or 4 renal toxicities. The median duration of neutropenia in patients achieving CR was 29 days after reinduction. 10% (6/57) of the patients died from infectious complications. Cytogenetic analyses were performed prior to first-line therapy in all patients. Patients with favorable cytogenetics treated with etoposide and mitoxantorne had 100% CR (3/3), patients with standard cytogenetics had 58% CR (19/33) and patients with unfavorable cytogenetics had 19% CR (4/21). Overall CR was achieved in 61% (22/36) of patients with favorable and standard cytogenetics. Our data suggest that the combination of etoposide and mitoxantorne is an active and well tolerated regimen, especially in patients with favorable and standard cytogenetics, and warrants further studies in prospective trials.

Abstract Abstract 1011 Poster Board I-33 Background: Addition of purine analogues to standard induction therapy of acute myeloid leukemia (AML) had previously been demonstrated to increase complete remission rate. The aim of this study was to analyze whether the use of cladribine or fludarabine during induction and consolidation increases the risk of infectious complications. Material and methods: 118 AML patients, included in two consecutive randomized trials between 1999-2006 in a single centre were analyzed. Induction therapy consisted of daunorubicin + cytarabine (DA-7, n=53) alone or in combination with cladribine or fludarabine (DAC-7 + DAF-7, n=65 ). Consolidation included one course of high-dose AraC + mitoxantrone and one course of high-dose AraC +/- purine analogues. A median age was 45(17-58) years and 48(20-60) years for patients treated with and without purine analogues, respectively. Results: The frequency of neutropenic fever as well as microbiologically documented bacterial, fungal and viral infections during induction and consolidation did not differ between two compared groups - receiving or not purine analogues. Time to infection occurrence and infection duration were similar in both study groups. During induction and both consolidation treatments significant lower values of lymphocytosis were observed in the group of patients treated with purine analogues. There was a slight tendency to increased rate of mucositis for patients treated with purine analogues (60% vs. 44.3%, p=0.07) during induction treatment, while infections affecting skin and soft tissues were significant frequent for patients treated without purine analogues (43.3% vs. 18%, p=0.03) during second consolidation treatment (high dose AraC). The usage of intravenous anti-infectious medications (antibiotics, antifungal, antiviral) and periods of hospitalization did not differ between two groups in this study. Conclusions: We conclude that the use of purine analogues, either cladribine or fludarabine along with conventional induction and consolidation therapy does not aggreviate infectious complications in adults with AML. Disclosures: No relevant conflicts of interest to declare.

ABSTRACTAlthough primary antifungal prophylaxis (PAP) is routinely administered in patients with acute myeloid leukemia (AML) during remission-induction and consolidation chemotherapy, the impact of PAP on the incidence of invasive fungal infections (IFIs) is not well described. We retrospectively analyzed the incidence of IFIs in 152 patients with AML who had been admitted to a tertiary cancer center between August 2009 and March 2011 and received PAP within 120 days after first remission-induction chemotherapy. We excluded patients who had undergone stem cell transplantation. Patients received a PAP drug with anti-Aspergillusactivity during 72% (7,660/10,572) of prophylaxis-days. The incidence of documented IFIs (definite or probable according to revised European Organization for Research and Treatment of Cancer [EORTC] criteria) was 2.0/1,000 prophylaxis-days (95% confidence interval [CI], 1.23 to 3.04). IFIs due to molds were more common than IFIs due to yeasts (1.5/1,000 prophylaxis-days versus 0.4/1,000 prophylaxis-days;P= 0.01). Echinocandin-based PAP (8.6 and 7.1/1,000 prophylaxis-days, respectively) was associated with higher rates of documented IFIs than anti-Aspergillusazoles (voriconazole or posaconazole) (2.4 and 1.1/1,000 prophylaxis-days, respectively) at both 42 days (P= 0.03) and 120 days (P< 0.0001) after first remission-induction chemotherapy. The incidence of overall (documented and presumed) IFIs (P< 0.001), documented IFIs (P< 0.01), and empirical antifungal therapies (P< 0.0001) was higher during the first 42 days than after day 42. Despite the broad use of PAP with anti-Aspergillusactivity, IFIs, especially molds, remain a significant cause of morbidity and mortality in AML patients, predominantly during the remission-induction phase. Patients receiving echinocandin-based PAP experienced higher rates of IFIs than did those receiving anti-Aspergillusazoles.

Abstract Background Patients with high risk (HR) myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) have significant toxicities such as mucositis, protracted neutropenia and severe infections when treated with standard chemotherapy. This had led to the development of ‘less intense’ chemotherapy (targeted therapy, TT). These treatments are expected to produce less toxicities, especially less immunosuppression. Antibiotic and antifungal prophylaxis are routinely given to patients undergoing intensive chemotherapy. It is not clear if the same strategy should be used for patients receiving less intensive chemotherapy. The objective of this study is to evaluate the outcome of patients receiving TT according to the use of antimicrobial prophylaxis. Methods We retrospectively reviewed the medical records of patients with AML and HR MDS that received TT as induction therapy from January 2000 to July 2007 at our institution. Baseline characteristics and antibiotic usage was recorded. All courses of TT received from start of therapy until outcome (response or failure) was assessed were evaluated, and infections or death occurring during any of these courses constituted an event. Results 225 patients received TT [decitabine or azacitidine n = 137 (61%); miscellaneous (tipifarnib, PKC412, imatinib, SAHA, and others) n=88 (39%)] for a total of 583 courses (median course per patient = 2). Median age was 72 years (range 13–89), 60% were male, 95% had Zubroad performance status ≤ 2 and 28% were neutropenic at the start of TT. None of the patients were placed in HEPA-filtered rooms (‘protected environment’) at any time. Each course of therapy was grouped into 1 of 4 groups based on the strategy use for infectious prophylaxis (table 1). Clinically documented infections and FUO were the most frequent type of infection reported in all the groups, followed by bacterial infections. Fungal infections were infrequent (total 5; group 1 = 1; group 2 = 2, group 3 = 2). There was no significant difference in the number of infectious episodes per course between the groups that received both antibacterial and antifungal prophylaxis vs. those who received no prophylaxis (p= 0.984). However, mortality was significantly higher during courses of TT administered without prophylaxis (p= 0.005). Conclusions As opposed to standard chemotherapy, fungal infections are infrequent in the patients treated with TT. Mortality is significantly higher in patients who did not receive any anti-microbial prophylaxis. The use of antibacterial and antifungal prophylaxis should be considered in patients receiving TT.

Abstract Background Despite fungal prophylaxis, invasive mold infections (IMIs) are a significant cause of morbidity and mortality in patients with acute myeloid leukemia (AML) receiving remission induction chemotherapy. The choice of antifungal prophylaxis agent remains controversial, especially in the era of novel targeted therapies. We conducted a retrospective case–control study to determine the incidence of fungal infections and to identify risk factors associated with IMI. Methods Adult patients with AML receiving anti-Aspergillus prophylaxis were included to determine the incidence of IMI per 1000 prophylaxis-days. Patients without and with IMI were matched 2:1 based on the day of IMI diagnosis, and multivariable models using logistic regression were constructed to identify risk factors for IMI. Results Of the 162 included patients, 28 patients had a possible (n = 22), probable, or proven (n = 6) diagnosis of IMI. The incidence of proven or probable IMI per 1000 prophylaxis-days was not statistically different between anti-Aspergillus azoles and micafungin (1.6 vs 5.4, P = .11). The duration of prophylaxis with each agent did not predict IMI occurrence on regression analysis. Older age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.004–1.081; P = .03) and relapsed/refractory AML diagnosis (OR, 4.44; 95% CI, 1.56–12.64; P = .003) were associated with IMI on multivariable analysis. Conclusions In cases that preclude use of anti-Aspergillus azoles for prophylaxis, micafungin 100 mg once daily may be considered; however, in older patients and those with relapsed/refractory disease, diligent monitoring for IMI is required, irrespective of the agent used for antifungal prophylaxis.
