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.

Abstract Background Therapy-related myeloid neoplasm (tMN) includes t-myelodysplasia (tMDS) and t-acute myeloid leukemia (tAML) and are serious late effects of the treatment of cancer. Prognosis of tMN is poor, related to the increased frequency of adverse cytogenetics and other clinical features which predict poor response to conventional treatment. Over the last years, azacitidine (AZA) has become the standard of treatment for high risk MDS (Silverman, JCO 2002; Fenaux, Lancet Oncol 2009) and has shown efficacy in AML. AZA represents an interesting option for patients with tMN considering its safety profile and its efficacy in poor prognosis subgroups of apparently de novo MDS patients including those with monosomy 7. Most prospective trials of AZA have excluded patients with tMN. Most tMN data are retrospective or registry studies (Bally, Leuk Res 2013). This abstract presents the results of 47 t-MN patients prospectively enrolled as a specific cohort in the E1905 study. Methods E1905 study is a randomized phase 2 study from the North American Leukemia Intergroup (NCT00313586, Prebet , ASH 2010) testing 10 days of AZA (50mg/m2/d s.c.) vs. 10 days of AZA + the histone deacetylase inhibitor entinostat (4 mg/m2/d PO days 3 and day 10). 6 cycles of treatment were planned; responding patients could receive up to 24 cycles. MDS, CMML, and AML with myelodysplasia-related changes were included. Patients with tMN were subsequently accrued as a separate cohort after amendment of the protocol. Response was assessed using IWG 2000 criteria (Cheson et al, Blood 2000); the primary endpoint of the overall trial was achievement of a normal hemogram in 25% of treated patients in either treatment arm. Results A total of 47 patients were included. Median age was 70 years (39y-83y), 45% male, and 94% of patients had ECOG PS 0-1. 29 patients could be subclassified as t-MDS and 18 as t-AML. At inclusion, median peripheral blood counts were: neutrophils 1.0 G/l, Platelets 35 G/L, Hemoglobin 9.2 g/l, peripheral blood blasts 0%, marrow blasts 14.0%. 68% of patients were RBC transfusion dependent and 40% platelet transfusion dependent. As expected, the cytogenetic evaluation showed a high frequency of unfavorable risk cytogenetics (74%) as compared to normal or intermediate risk cytogenetics (26%). Baseline characteristics were not statistically different between the 2 arms. 24 patients were treated with AZA monotherapy and 23 with AZA+entinostat. The median number of administered cycles was 4 and was significantly higher in patients treated with AZA monotherapy (6 cycles vs.3 cycles, p=0.008). 8 patients in the combination arm and 1 patient in the AZA monotherapy arm died of infection or hemorrhage before cycle 3. In an intent to treat analysis, overall response rates (CR, PR, or trilineage Hematologic improvement) were 11/24 (46%) in AZA monotherapy (95% CI 26 – 67%) and 4/23 (17%) in the combination arm (95% CI 5 – 39%, p=0.06 comparing the two arms). Median overall survival in the two arms were 12.8 months and 5.7 months (p=0.008). Conclusions In this group of very high risk patients with therapy-related myeloid neoplasms, the use of the novel 50 * 10 schedule of azacitidine monotherapy appears effective, with response rates comparable to those for patients with de novo MDS/AML treated on the same protocol (74 pts, 40% with unfavorable cytogenetics, ORR=32%, median OS=18 months). Because there are no prospective data examining the approved dose schedule of AZA (75 mg/m2/day * 7 days), it is not clear if this surprisingly high response rate derives from the current extended schedule of lower dose AZA, or would be true with standard dose AZA as well. This high response may enable many of these patients to proceed to allogeneic stem cell transplant. Entinostat combined with azacitidine at the dose and schedule applied in E1905 does not appear to be effective and tolerable as compared to azacitidine alone. Disclosures: Prebet: CELGENE: Honoraria.

Abstract Background: Venetoclax combined with azacitidine has been demonstrated to have a favorable overall response rate and tolerable safety in acute myeloid leukemia (AML) patients who are unfit for intensive chemotherapy. Methods: This study retrospectively recruited 64 Adults (≥18 years) with newly diagnosed AML ineligible for intensive chemotherapy who had received at least one cycle of treatment with venetoclax plus azacitidine. The primary endpoint was overall survival (OS). Secondary endpoints were remission rates. Safety was evaluated based on the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. Results: The median age of the enrolled patients was 69 years. The median OS for the cohort was 15.5 months, with 21.2 months for complete responders as opposed to 13.3 months for those who did not achieve a complete response. 39 (60.9%) patients achieved composite complete remission (complete remission (CR) + CR with incomplete count recovery (CRi)) and 7/64 (10.9%) achieved morphologic leukemia-free state (MLFS) with a median follow-up time of 14.7 months. The median CR+CRi duration was 10.9 months. It is noteworthy that 43/64 (67.2%) patients achieved the best response after one cycle with a median time of 1.2 months. Normal karyotype (P=0.015) was significantly associated with extended OS in multivariate analysis, while higher white blood cell count (P=0.032), lower platelet count (p=0.018) and antifungal drug combination (P=0.013) were predictors of shortened OS in univariate analysis. Common grade 3/4 Adverse Events (AEs) included infection (68%) and hematological AEs consisting of neutropenia (93%), anemia (90%), leukopenia (86%), thrombocytopenia (77%) and febrile neutropenia (52%). The median neutropenia duration was 16 days. Conclusions: The novel venetoclax-azacitidine combination regimen showed prolonged survival period, promising efficacy, sound and rapid response, and superior tolerance in Chinese patients newly diagnosed AML.

PURPOSE To explore trial-level and patient-level associations between response (complete remission [CR] and CR + CR with incomplete hematologic [CRi] or platelet [CRp] recovery), event-free survival (EFS), and overall survival (OS) in newly diagnosed acute myeloid leukemia (AML) trials of intensive chemotherapy. METHODS We identified data from eight randomized, active-controlled trials of intensive chemotherapy submitted to the US Food and Drug Administration for treatment of newly diagnosed AML (N = 4,482). Associations between trial-level odds ratios (ORs) for CR and CR + CRi or CRp, and hazard ratios (HRs) for EFS and OS were analyzed using weighted linear regression models. We performed patient-level responder analyses to compare OS by response using pooled data from all studies. RESULTS In trial-level analyses, association between HR for OS and OR for CR was moderate (R2 = 0.49; 95% CI, 0.05 to 0.86), as was the association with OR for CR + CRi or CRp (R2 = 0.48; 95% CI, 0.05 to 0.99). For OS versus EFS, a strong association was observed (R2 = 0.87; 95% CI, 0.47 to 0.98) when EFS definitions were harmonized across trials using raw data. In the patient-level responder analyses, patients who achieved CR had better OS compared with CRi or CRp responders (0.73; 95% CI, 0.64 to 0.84) and nonresponders (HR, 0.33; 95% CI, 0.31 to 0.37). CONCLUSION On a trial level, there is a moderate association between OS and CR rate. A strong association between EFS and OS was observed. However, CIs were wide, and results became moderate using alternative definitions for EFS. Patient-level analyses showed CR responders have better OS compared with CRi or CRp responders and nonresponders. A therapy in newly diagnosed AML with benefit in EFS or substantial benefit in CR rate would be likely to have an OS effect.
