PURPOSE Standard cytotoxic induction chemotherapy for acute myeloid leukemia (AML) results in prolonged neutropenia and risk of infection. Romyelocel-L is a universal, allogeneic myeloid progenitor cell product being studied to reduce infection during induction chemotherapy. PATIENTS AND METHODS One hundred sixty-three patients with de novo AML (age ≥ 55 years) receiving induction chemotherapy were randomly assigned on day 0 (d0), of whom 120 were evaluable. Subjects received either romyelocel-L infusion on d9 with granulocyte colony-stimulating factor (G-CSF) starting daily d14 (treatment group) or G-CSF daily alone on d14 (control) until absolute neutrophil count recovery to 500/µL. End points included days in febrile episode, microbiologically defined infections, clinically diagnosed infection, and days in hospital. RESULTS Mean days in febrile episode was shorter in the treatment arm from d15 through d28 (2.36 v 3.90; P = .02). Similarly, a trend toward decreased microbiologically defined infections and clinically diagnosed infection in the treatment arm was observed from d9 to d28 (35.6% v 47.5%; P = .09), reaching a statistically significant difference from d15 to d28 (6.8% v 27.9%; P = .002). Because of this, antibacterial or antifungal use for treatment of an infection was significantly less in the treatment group (d9-d28: 44.1% v 63.9%; P = .01). Significantly fewer patients in the treatment arm received empiric antifungals from d9 tod28 (42.4% v 63.9%; P = .02) and d15-d28 (42.4% v 62.3%; P = .02). Patients in the treatment arm also had 3.2 fewer hospital days compared with control (25.5 v 28.7; P = .001). Remission rates and days to absolute neutrophil count recovery were similar in the two groups. No patients in the romyelocel-L plus G-CSF group died because of infection compared with two patients in the control arm. No graft-versus-host disease was observed. CONCLUSION Subjects receiving romyelocel-L showed a decreased incidence of infections, antimicrobial use, and hospitalization, suggesting that romyelocel-L may provide a new option to reduce infections in patients with AML undergoing induction therapy.

Abstract Abstract 1417 Background: We have previously shown that for patients with acute myeloid leukemia (AML) treated with induction chemotherapy with cytarabine (ara-C) plus an anthracycline, the day of blast clearance from peripheral blood (PB) is a powerful prognostic marker. Earlier PB blast (but not white blood cell [WBC]) clearance portends improved overall survival (OS). We expanded our investigation to include patients with AML undergoing induction chemotherapy with ara-C (1.5g/m2 ×3 days) plus idarubicin (12mg/m2×3 days) that is, the AI regimen, plus sorafenib (400mg orally twice daily). Patients and Methods: We reviewed the clearance of PB blast and WBC (PB blasts = 0%, WBC≤0.1×109/dL), for patients with AML (except APL) undergoing AI alone (n=168) or AI+sorafenib (n=75). Patient characteristics for the AI alone group (n=168) were as follows: median age 55 years (range, 19–72), diploid cytogenetics (n=57, 34%), poor cytogenetics (n=61, 36%), FLT3-ITD positive (n=15, 9%), FLT3-negative (n=122, 73%), median WBC 5.0×109/dL (range, 0.3–132.3), median platelets 37×109/dL (range, 1–581), median hemoglobin 9.1g/dL (range, 4.0–13.2), median PB blasts 15% (range, 1–96), median BM blasts 42% (range, 1–96). Patient characteristics for the AI+sorafenib group (n=75) were as follows: median age 52 years (range, 18–66), diploid cytogenetics (n=38, 51%), poor cytogenetics (n=10, 13%), FLT3-ITD (n=25, 33%), FLT3-negative (n=48, 64%) median WBC 5.9×109/dL (range, 0.6–228.5), median platelets 51×109/dL (range 7–306), median hemoglobin 9.2g/dL (range, 7.4–12.6), median PB blasts 21% (range 0–98), median BM blasts 56% (range 6–98). Results: The overall response rate (ORR=CR+CRp) in the AI group was 63% (58%+5%) and 50 patients (30%) were resistant to therapy. The ORR in the AI+sorafenib group was 79% (72%+7%) and 11 patients (15%) were resistant. We analyzed OS by dividing patients based on the day of PB blast clearance: group 1 (0–1 days), 2 (2–3 days), 3 (4–5 days), 4 (6–8 days), and 5 (>8 days). For the patients receiving AI induction therapy, a total of 32, 59, 38, 18, and 2 patients were included in groups 1–5, and median OS for groups 1–4 were 167, 48, 67, and 25 weeks respectively. A logrank test comparison revealed these four OS curves were significantly different (p-value=0.0015). For the AI treatment group, earlier blast disappearance corresponded with better OS. In contrast, for patients in the AI+sorafenib group, the correlation between day of PB blast clearance and OS was less clear. A total of 10, 23, 25, 6, and 3 patients were included in groups 1–5. The median OS for groups 1, 3, and 4 were 101, 74, and 66 weeks respectively, and the median survival for group 2 could not be estimated because the curve did not fall below 0.5. The difference between these four survival curves was not significantly different (p-value=0.35). Survival differences for the AI group were more clearly demarcated when patients were divided based on blast disappearance within 0–5 days or >5 days (p-value=0.0004). A similar analysis in the AI+sorafenib group revealed no significantly different OS (p-value=0.13). Among patients in the AI+sorafenib treatment group, the mean day of blast disappearance for FLT3-ITD versus FLT3-negative patients was 5.2 vs. 4.5 days, and this difference was not statistically significant (p-value=0.33). While FLT3-ITD patients who cleared their blasts within 0–3 days (n=10) tended to have better OS survival than FLT3-ITD patients who cleared their blasts after 3 days (n=13), the difference in OS curves did not reach significance (p-value=0.18). Conclusion: The day of PB blast clearance is prognostic among patients receiving classic induction chemotherapy, where early clearance predicts better long-term outcomes. The addition of a targeted agent to a standard induction regimen limits the prognostic power of early PB blast clearance. We are currently investigating a novel mathematical approach to evaluate the prognostic value of clearance of peripheral blasts compared to WBC after initiation of therapy in patients receiving targeted agents during induction therapy; the approach aims to integrate the prognostic impact of FLT3 and NPM1 in combination with cytoreduction kinetics to better identify prognostically distinct groups. Disclosures: Off Label Use: Plerixafor plus G-CSF as a part of conditioning in allogenic transplant for AML/MDS.

Midostaurin is a tyrosine multikinase inhibitor approved for the treatment of patients with newly diagnosed acute myeloid leukemia (AML) with mutated Fms-like tyrosine kinase-3. We describe a case report of a 49-year-old AML patient treated with an intensive chemotherapy regimen followed by midostaurin. After achieving complete remission with blood count recovery, he suffered from a serious, rare complication of necrotizing hemorrhagic gastritis with no evidence of infection or malignant infiltration, possibly associated with midostaurin therapy.

Background: Acute Myeloid Leukemia syndrome (AML) is a hematologic malignancy which is due to clonal extensive proliferation of leukemic precursor cells and is rapidly fatal unless treated or response to chemotherapy. Cytogenetic findings have important role in prognosis and categorization of AML. The aim of this study was to investigate the expression changes in CX3CL1 and Interlukin-6 (IL-6) genes before and after chemotherapy as remission induction therapy in AML patients. Materials and Methods: In this study 69 patients (36 males, 33 female) with AML was selected from tertiary medical heath center. A quantitative polymerase chain reaction (PCR) was done for mRNA expression of CX3CL1 and IL-6genes before and after induction chemotherapy. To obtain expression changes in CX3CL1 and IL-6genes, we used 2-ΔΔCT method. Results: The expression of CX3CL1 and IL-6 was significantly increased after induction chemotherapy. Also, the ΔCt mean of CX3CL1 and IL-6 mRNA was not significant between AML subtype groups. Conclusion: In conclusion, as we showed that chemotherapy significantly increase the expression of CX3CL1 and IL-6 which can be used as a prognostic factor of AML.

This single-center retrospective study of invasive fungal disease (IFD) enrolled 251 adult patients undergoing induction chemotherapy for newly diagnosed acute myeloid leukemia (AML) from 2014–2019. Patients had primary AML (n = 148, 59%); antecedent myelodysplastic syndrome (n = 76, 30%), or secondary AML (n = 27, 11%). Seventy-five patients (30%) received an allogeneic hematopoietic cell transplant within the first year after induction chemotherapy. Proven/probable IFD occurred in 17 patients (7%). Twelve of the 17 (71%) were mold infections, including aspergillosis (n = 6), fusariosis (n = 3), and mucomycosis (n = 3). Eight breakthrough IFD (B-IFD), seven of which were due to molds, occurred in patients taking antifungal prophylaxis. Patients with proven/probable IFD had a significantly greater number of cumulative neutropenic days than those without an IFD, HR = 1.038 (95% CI 1.018–1.059), p = 0.0001. By cause-specific proportional hazards regression, the risk for IFD increased by 3.8% for each day of neutropenia per 100 days of follow up. Relapsed/refractory AML significantly increased the risk for IFD, HR = 7.562 (2.585–22.123), p = 0.0002, and Kaplan-Meier analysis showed significantly higher mortality at 1 year in patients who developed a proven/probable IFD, p = 0.02. IFD remains an important problem among patients with AML despite the use of antifungal prophylaxis, and development of IFD is associated with increased mortality in these patients.
