Jennifer R. Brown, MD, PhD, of Dana-Farber Cancer Institute, discusses phase III findings of the ALPINE study, which showed that zanubrutinib is more efficacious and better tolerated than ibrutinib as a treatment for patients with relapsed or refractory chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). In this first head-to-head comparison of the two BTK inhibitors, the superior progression-free survival of zanubrutinib was observed across all major subgroups, including high-risk patients (Abstract LBA-6).
Mark R. Litzow, MD, of the Mayo Clinic, discusses phase III results from the ECOG-ACRIN E1910 Trial, which show that adding blinatumomab to consolidation chemotherapy resulted in a significantly better overall survival in adult patients aged 30 to 70 years with newly diagnosed B-lineage acute lymphocytic leukemia (ALL) who were measurable residual disease–negative after receiving intensification chemotherapy. The authors believe this may represent a new standard of care for this population (Abstract LBA-1).
Richter syndrome is an aggressive lymphoma that develops in up to 1% of patients with chronic lymphocytic leukemia (CLL) and it serves as an example of histologic transformation. While recent advances have transformed the treatment landscape of CLL, Richter syndrome remains associated with poor...
Zanubrutinib showed superior efficacy to ibrutinib—with fewer side effects—in the first head-to-head comparison between the Bruton’s tyrosine kinase (BTK) inhibitors among patients with chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL), according to data presented by Jennifer...

In the multicenter prospective trial...
A three-drug combination that showed success at sending patients with chronic lymphocytic leukemia (CLL) into deep remissions in a clinical trial may be effective at treating patients with high-risk types of the disease, according to new findings presented by Ryan et al at the 2022 American Society ...
The use of stem cell transplantation for acute myeloid leukemia increased by about 55% worldwide from 2009 to 2016, according to new findings presented by Niederweiser et al at the 64th American Society of Hematology (ASH) Annual Meeting and Exposition (Abstract 3638). Although the largest...
Irene Roberts, MD, of Oxford’s Weatherall Institute of Molecular Medicine, discusses children with Down syndrome, who have a more than 100-fold increased risk of developing acute myeloid leukemia before their fourth birthday compared to children without Down syndrome. Their risk of acute lymphoblastic leukemia is also increased by around 30-fold. Dr. Roberts details current knowledge about the biologic and molecular basis of this relationship between leukemia and Down syndrome, the role of trisomy 21 in leukemogenesis, and the clinical implications of these findings.
Abdul Rahman Al Armashi, MD, of Seidman Cancer Center, Case Western University, University Hospitals Cleveland Medical Center, discusses a retrospective analysis, using a CDC database, in one of the largest subgroup-based racial population studies analyzing mortality trends in patients with acute myeloid leukemia (AML). Between 2000 and 2019, AML mortality was the highest in Whites and the lowest in American Indians or Alaska Natives. The highest rate of increase in mortality was seen in Asians or Pacific Islanders. Dr. Al Armashi talks about the many variables that might contribute to these inequalities (Abstract 600).
Anand P. Jillella, MD, of Georgia Cancer Center at Augusta University, discusses results from the ECOG-ACRIN EA9131 Trial, which showed that using a simplified treatment algorithm and management recommendations made by a group of specialists, resulted in a dramatic improvement in 1-year survival of patients with acute promyelocytic leukemia (Abstract 421).
Andrew Matthews, MD, of the Abramson Cancer Center, University of Pennsylvania, discusses findings from a large, multicenter study that showed superior outcomes with 7 + 3 chemotherapy (cytarabine continuously for 7 days, along with short infusions of an anthracycline on each of the first 3 days) vs venetoclax in patients with acute myeloid leukemia (AML). In this real-world data set, the 7 + 3 cohort outperformed historical benchmarks in overall survival and early mortality, perhaps reflecting improved later lines of therapy and patient selection. Prospective studies (such as NCT04801797) must confirm the superiority of intensive chemotherapy (Abstract 426).
Researchers from the University of Pennsylvania’s Abramson Cancer Center presented preliminary results of an ongoing phase I clinical trial demonstrating successful retreatment with chimeric antigen receptor (CAR) T-cell therapy for patients whose cancers relapsed after previous CAR T-cell therapy. ...
Researchers from The University of Texas MD Anderson Cancer Center showed that inhibiting menin with an oral small-molecule inhibitor of the menin-KMT2A interaction, SNDX-5613—now named revumenib—yielded encouraging responses for patients with advanced acute leukemias and KMT2A rearrangements or...
Jorge E. Cortes, MD, of Georgia Cancer Center at Augusta University, discusses new findings on vodobatinib, which was administered to patients with chronic-phase Philadelphia chromosome–positive chronic myeloid leukemia (CML) and appeared to be efficacious and safe in people who had received therapy with two or three prior tyrosine kinase inhibitors (TKIs). Vodobatinib remains a potential option for these highly refractory patients. A phase II study (NCT02629692) of vodobatinib is ongoing in CML patients whose disease has failed to respond to three or more TKIs, including ponatinib (Abstract 84).
Elias Jabbour, MD, of The University of Texas MD Anderson Cancer Center, discusses an analysis confirming that olverembatinib is a potentially viable treatment option for patients with chronic myeloid leukemia (CML) and Philadelphia chromosome–positive acute lymphoblastic leukemia (ALL), including those with CML whose disease did not respond to ponatinib or asciminib, or who had a T315I mutation (Abstract 82).
Eunice S. Wang, MD, of Roswell Park Comprehensive Cancer Center, discusses the outcomes of patients newly diagnosed with acute myeloid leukemia (AML) who were treated with cytarabine plus daunorubicin plus gemtuzumab ozogamicin (GO). These patients experienced higher rates of measurable residual disease–negative complete remission and complete remission with incomplete count recovery, compared to those treated with cytarabine plus idarubicin daunorubicin alone. Although adding GO was not associated with improved overall survival, longer follow-up is warranted to determine an absolute survival advantage of this regimen (Abstract 58).
The results of a new study answer some questions and raise new ones about the optimal treatment strategy for children and young adults living with acute lymphoblastic leukemia (ALL) or lymphoblastic leukemia (LBL). The randomized study is the first to test whether the use of a shorter, higher-dose...
