Special Issue Information

Dear Colleagues, 

Acute myeloid leukemia (AML) has always posed a therapeutic challenge due to its molecular and cytogenetic complexity. For the first time in decades, advances in treatment through the approval of novel agents and combinations, have been made. Long-term disease-free survival had plateaued at less than 30% at 5 years; however, in the last few years, a small, but steady increase has been seen thanks to the advancements in novel therapies. The exploration of novel mechanisms and immune system enhancement as therapeutic targets for the treatment of AML continues.

This Special Issue will highlight the clinical trials and advances in supportive care for acute myeloid leukemia. 

You may choose our Joint Special Issue in Current Oncology.

Abstract
Background: Despite the development of targeted therapies in first-line AML, complete remissions (CR) cannot be achieved in 30–40%, and relapse rates remain high. In R/R AML the intensive treatment regimen of fludarabine, cytarabine, idarubicin combined with venetoclax (FLA-VIDA) showed improved remission rates compared [...] Read more.
Background: Despite the development of targeted therapies in first-line AML, complete remissions (CR) cannot be achieved in 30–40%, and relapse rates remain high. In R/R AML the intensive treatment regimen of fludarabine, cytarabine, idarubicin combined with venetoclax (FLA-VIDA) showed improved remission rates compared to FLA-IDA. In this retrospective single-center analysis, we investigated the efficacy and safety of dose-reduced FLA-IDA with and without venetoclax to minimize the risk of infectious complications and excessive myelosuppression; Methods: Between 2011 and 2023, 89 R/R AML patients were treated with dose-reduced FLA-IDA (fludarabine 30 mg/m2 day 1–4, cytarabine 2000 mg/m2 day 1–4, idarubicin 10 mg/m2 day 1 + 4). From 2019 onwards, venetoclax was added (day 1 100 mg, day 2 200 mg, day 3–14 400 mg); Results: Significantly improved response rates were observed with 60.0% vs. 38.8% CR/CRi (p = 0.0297) and 74.5% vs. 47.3% (p = 0.032) CR/CRi/MLFS for FLA-VIDA vs. FLA-IDA. Further, with FLA-VIDA significantly improved event-free survival (EFS) was observed (p = 0.026). Overall survival (OS) was similar in FLA-VIDA and FLA-IDA treated patients. The most common treatment-related toxicities were hematological adverse events, but they were comparable between groups. The time to neutrophil and platelet recovery were similar in responding patients treated with FLA-VIDA vs. FLA-IDA; Conclusions: Dose-reduced FLA-VIDA significantly improved response rates without increases in toxicity, showing promise for an improved R/R AML treatment.

Chemotherapy remains a primary treatment for younger AML patients, though many relapse. Data from our group have shown that highly phosphorylated S6 in blasts may predict response to sirolimus given with chemotherapy. We report the results of a phase I study of this combination in newly diagnosed AML and the pharmacodynamic analysis of pS6 before and after treatment. Subjects received sirolimus (12 mg on day 1, 4 mg daily, days 2–10), then idarubicin and cytarabine (days 4–10). Response was assessed at hematologic recovery or by day 42 using a modified IWG criteria. Fifty-five patients received sirolimus. Toxicity was similar to published 7 + 3 data, and 53% had high-, 27% intermediate-, and 20% favorable-risk disease. Forty-four percent of the high-risk patients entered into CR/CRp. Seventy-nine percent of the intermediate-risk subjects had a CR/CRp. All favorable-risk patients had a CR by day 42; 9/11 remained alive and in remission with a median follow-up of 660 days. Additionally, 41/55 patients had adequate samples for pharmacodynamic analysis. All patients demonstrated activation of S6 prior to therapy, in contrast to 67% seen in previous studies of relapsed AML. mTORC1 inhibition was observed in 66% of patients without enrichment among patients who achieved remission. We conclude that sirolimus and 7 + 3 is a well-tolerated and safe regimen. mTORC1 appears to be activated in almost all patients at diagnosis of AML. Inhibition of mTORC1 did not differ based on response, suggesting that AML cells may have redundant signaling pathways that regulate chemosensitivity in the presence of mTORC1 inhibition.

KMT2A-rearranged leukemias are a highly aggressive subset of acute leukemia, characterized by poor prognosis and frequent relapses despite intensive treatment. Menin inhibitors, which target the critical KMT2A–menin interaction driving leukemogenesis, have shown promise in early clinical trials. However, resistance to these inhibitors, often driven by menin mutations or alternative oncogenic pathways, remains a significant challenge. This review explores combination therapies aimed at overcoming resistance and improving patient outcomes. Potential strategies include inhibiting DOT1L, a histone methyltransferase essential for KMT2A-driven transcription, and BRD4, a regulator of transcriptional super-enhancers. Additionally, targeting MYC, a key oncogene frequently upregulated in KMT2A-rearranged leukemia, offers another approach. Direct inhibition of KMT2A-fusion proteins and c-MYB, a transcription factor critical for leukemic stem cell maintenance, is also explored. By integrating these diverse strategies, we propose a comprehensive therapeutic paradigm that targets multiple points of the leukemic transcriptional and epigenetic network. These combination approaches aim to disrupt key oncogenic pathways, reduce resistance, and enhance treatment efficacy, ultimately providing more durable remissions and improved survival for patients with KMT2A-rearranged leukemias.
