Safety Concerns Prompt Pause of Magrolimab Trials
Cancer Discov 2022 Apr 1;12(4):877-878.PMID:35140129DOI:10.1158/2159-8290.CD-NB2022-0012.
Gilead paused enrollment in trials of its anti-CD47 therapy Magrolimab following suspicions of a safety issue experienced by patients with acute myeloid leukemia or myelodysplastic syndrome who received it in combination with the chemotherapeutic agent azacitidine.
Updates on targeted therapies for acute myeloid leukaemia
Br J Haematol 2022 Jan;196(2):316-328.PMID:34350585DOI:10.1111/bjh.17746.
In the past few years research in the underlying pathogenic mechanisms of acute myeloid leukaemia (AML) has led to remarkable advances in our understanding of the disease. Cytogenetic and molecular aberrations are the most important factors in determining response to chemotherapy as well as long-term outcome, but beyond prognostication are potential therapeutic targets. Our increased understanding of the pathogenesis of AML facilitated by next-generation sequencing has spurred the development of new compounds in the treatment of AML, particularly the creation of small molecules that target the disease on a molecular level. Many of the hopeful predictions outlined in our AML review of 2018 are now therapeutic realities: gemtuzumab ozogamicin, venetoclax, FLT3 inhibitors (midostaurin, gilteritinib), IDH inhibitors (ivosidenib, enasidenib), CPX-351, glasdegib, oral decitabine, and oral azacitidine. Others may soon be (quizartinib, APR246 Magrolimab, menin inhibitors). The wealth of positive data allows reconsideration of what might soon be new standards of care in younger and older patients with AML. In this review we give an overview of recently approved therapies in AML and address present and future research directions.
Advances in myelodysplastic syndrome
Curr Opin Oncol 2021 Nov 1;33(6):681-686.PMID:34474438DOI:10.1097/CCO.0000000000000790.
Purpose of review: In this review, the focus is on the most recent improvements in diagnosis, prognostication and therapy of myelodysplastic syndromes (MDS) and on their relevance for clinical management. Recent findings: Analytical methods to refine cytogenetic and molecular assessment of MDS have been proposed, improving prognostic stratification obtained from integration of clinical and genomic data. Novel agents with very different mode of action, as single drugs or added to HMA backbone, show promising clinical results in LR-MDS and HR-MDS. Luspatercept has obtained approval given the fact that in transfusion-dependent erythropoietic-stimulating agent resistant/relapsed LR-MDS induced nearly 50% of transfusion independence. Another investigational agent showing efficacy and possibly disease modifying activity in the same setting is the telomerase inhibitor imetelstat. Results from phase II study with azacytidine and pevonedistat indicate the concrete possibility to enhance durable responses compared with azacitidine single drug. In the same direction are the preliminary results of other agents with different mode of action: Magrolimab, venetoclax, sabatolimab, as well as the targeted therapy with enasidenib and ivosidenib. New posttransplant maintenance strategies may concur to prolong response. Summary: Better diagnosis and prognostic stratification may allow a more precise and personalized treatment of MDS with novel agent combinations leading to improved therapeutic algorithms.
Current and emerging strategies for management of myelodysplastic syndromes
Blood Rev 2021 Jul;48:100791.PMID:33423844DOI:10.1016/j.blre.2020.100791.
Myelodysplastic syndromes (MDS) are characterized by ineffective hematopoiesis with varying degrees of dysplasia and peripheral cytopenias. MDS are driven by structural chromosomal alterations and somatic mutations in neoplastic myeloid cells, which are supported by a tumorigenic and a proinflammatory marrow microenvironment. Current treatment strategies for lower-risk MDS focus on improving quality of life and cytopenias, while prolonging survival and delaying disease progression is the focus for higher-risk MDS. Several promising drugs are in the horizon, including the hypoxia-inducible factor stabilizer roxadustat, telomerase inhibitor imetelstat, oral hypomethylating agents (CC-486), TP53 modulators (APR-246 and ALRN-6924), and the anti-CD47 antibody Magrolimab. Targeted therapies approved for acute myeloid leukemia treatment, such as isocitrate dehdyrogenase inhibitors and venetoclax, are also being studied for use in MDS. In this review, we provide a brief overview of pathogenesis and current treatment strategies in MDS followed by a discussion of newer agents that are under clinical investigation.
Emerging Targeted Therapy for Specific Genomic Abnormalities in Acute Myeloid Leukemia
Int J Mol Sci 2022 Feb 21;23(4):2362.PMID:35216478DOI:10.3390/ijms23042362.
We describe recent updates of existing molecular-targeting agents and emerging novel gene-specific strategies. FLT3 and IDH inhibitors are being tested in combination with conventional chemotherapy for both medically fit patients and patients who are ineligible for intensive therapy. FLT3 inhibitors combined with non-cytotoxic agents, such as BCL-2 inhibitors, have potential therapeutic applicability. The menin-MLL complex pathway is an emerging therapeutic target. The pathway accounts for the leukemogenesis in AML with MLL-rearrangement, NPM1 mutation, and NUP98 fusion genes. Potent menin-MLL inhibitors have demonstrated promising anti-leukemic effects in preclinical studies. The downstream signaling molecule SYK represents an additional target. However, the TP53 mutation continues to remain a challenge. While the p53 stabilizer APR-246 in combination with azacitidine failed to show superiority compared to azacitidine monotherapy in a phase 3 trial, next-generation p53 stabilizers are now under development. Among a number of non-canonical approaches to TP53-mutated AML, the anti-CD47 antibody Magrolimab in combination with azacitidine showed promising results in a phase 1b trial. Further, the efficacy was somewhat better in patients with the TP53 mutation. Although clinical evidence has not been accumulated sufficiently, targeting activating KIT mutations and RAS pathway-related molecules can be a future therapeutic strategy.
