PD-1 blockade enhances the function of antitumor T cells and antibody-dependent, cell-mediated cytotoxicity (ADCC) of NK cells. In a single-center, open-label, phase 2 trial, we tested the combination of pembrolizumab, an anti-PD-1 monoclonal antibody, and rituximab, an anti-CD20 monoclonal antibody that induces ADCC, in 30 patients with follicular lymphoma (FL) with rituximab-sensitive disease who had relapsed after ≥1 prior therapy. Pembrolizumab was administered at 200 mg IV every 3 weeks for up to 16 cycles, and rituximab was given at 375 mg/m2 IV weekly for 4 weeks in cycle 1 only. The most common grade 3/4 adverse events (AEs) were …

The majority of RUNX1 mutations in acute myeloid leukemia (AML) are missense or deletion-truncation and behave as loss-of-function mutations. Following standard therapy, AML patients expressing mtRUNX1 exhibit inferior clinical outcome than those without mutant RUNX1. Studies presented here demonstrate that as compared with AML cells lacking mtRUNX1, their isogenic counterparts harboring mtRUNX1 display impaired ribosomal biogenesis and differentiation, as well as exhibit reduced levels of wild-type RUNX1, PU.1, and c-Myc. Compared with AML cells with only wild-type RUNX1, AML cells expressing mtRUNX1 were also more sensitive to the protein translation inhibitor homoharringtonine (omacetaxine) and BCL2 inhibitor venetoclax. Homoharringtonine treatment repressed …

The B-cell lymphoma 2 (BCL-2) inhibitor venetoclax (VEN) in combination with lower-intensity therapy is an efficacious treatment for acute myeloid leukemia (AML). VEN in combination with the hypomethylating agent azacitidine improved rates of response and measurable residual disease (MRD)-negative remissions in addition to overall survival in the pivotal phase 3 VIALE-A trial compared with azacitidine monotherapy and has since emerged as the current standard of care in older or unfit patients with AML. In younger, fit patients with AML, intensive induction and consolidation chemotherapy (IC) is commonly employed as frontline therapy; however, relapse remains the principal cause of treatment failure …


Prediction Of Early (4-Week) Mortality In Acute Myeloid Leukemia With Intensive Chemotherapy, Koji Sasaki, Tapan Kadia, Kebede Begna, Courtney D Dinardo, Gautam Borthakur, Nicholas J Short, Nitin Jain, Naval Daver, Elias Jabbour, Guillermo Garcia-Manero, Guillermo Montalban Bravo, Lucia Masarova, Sherry Pierce, Marina Konopleva, Farhad Ravandi, Ayalew Tefferi, Hagop Kantarjian Jan 2022

The progress with intensive chemotherapy and supportive care measures has improved survival in patients with newly diagnosed acute myeloid leukemia (AML). Given the recent development of effective low intensity therapies, an optimal decision on the therapy intensity may improve survival through the avoidance of early mortality. We reviewed the outcome of 3728 patients with newly diagnosed AML who received intensive chemotherapy between August 1980 and May 2020. Intensive chemotherapy was defined as a cumulative cytarabine dose ≥ 700 mg/m2 during induction therapy. We divided the whole cohort into a training and validation group at a 3:1 ratio. The population was …


Dnmt3a Haploinsufficiency Provokes Hematologic Malignancy Of B-Lymphoid, T-Lymphoid, And Myeloid Lineage In Mice, Garland Michael Upchurch Aug 2017

Dnmt3a Haploinsufficiency Provokes Hematologic Malignancy Of B-Lymphoid, T-Lymphoid, And Myeloid Lineage In Mice, Garland Michael Upchurch

Theses & Dissertations

DNA methyltransferase 3A (DNMT3A) is a master epigenetic regulator of benign and malignant hematopoiesis. To dissect the biological consequences of homozygous and heterozygous Dnmt3a inactivation in malignant hematopoiesis, we generated Dnmt3a homozygous null (Dnmt3aΔ/Δ) and Dnmt3a heterozygous (Dnmt3a+/–) mice and compared the presentations of hematologic malignancies between cohorts. Bi-allelic inactivation of Dnmt3a results in the presentation of mature lymphoid neoplasms resembling chronic lymphocytic leukemia (CLL; B220+CD19+CD5+; 88% penetrance (37/42)) and CD8+ peripheral T-cell lymphoma (PTCL; TCRβ+CD3+CD8+CD4—; 40% penetrance (17/42)). …


Correlation Matrix Analysis Identifies Gene Signatures Of Immune Cell Subsets And Their Interactions In Follicular Lymphoma, Jason R. Westin May 2015

Correlation Matrix Analysis Identifies Gene Signatures Of Immune Cell Subsets And Their Interactions In Follicular Lymphoma, Jason R. Westin

Dissertations and Theses (Open Access)

There are important but ill-defined interactions between benign immune cell subsets and neoplastic B cells within follicular lymphoma (FL). Using the novel technique of correlation matrix analysis (CMA) of publicly available FL whole-tumor gene expression profiling (GEP) data, we have identified signatures of immune cell subsets. Overall survival correlated most highly with a model using signatures of macrophages, T cells, and stroma, which was able to add significantly to existing clinical prognostic tools. From our own data of a cohort of 43 FL tumors sorted into B-cell and non-B cell (NB) fractions for GEP, CMA of the tumor infiltrating NB …
