ATLANTA, USA—A new research method has elucidated cellular processes (involving mutated TP53 oncogene) that can convert a relatively benign myeloproliferative neoplasm into acute myeloid leukemia.
Findings from Oxford University in the UK (using the novel genetic sequencing tool called: single cell multi omics) were reported at the American Society of Hematology (ASH) 2021 Annual Meeting Plenary Session, by Oxford scientist Alba Rodriguez-Meira DPhil, PhD, from the Weatherall Institute of Molecular Medicine in Oxford—winner of an ASH Abstract Achievement Award. She discusses her award-winning research with Audio Journal of Oncology reporter Peter Goodwin.
In an inspiring oral presentation at ASH, Alba Rodriguez-Meira explained how her group’s research on the TP53 gene had made it possible to analyze the genome of a large number of individual cells from a relatively small sample of patients and healthy controls. https://ash.confex.com/ash/2021/webprogram/Paper150191.html
The study findings should provide predictive, prognostic and therapeutic tools that could improve otherwise dismal outcomes in subgroups of patients with hematologic malignancies.
Our single cell multi omics analysis, coupled with in-vitro and in-vivo analysis, has allowed us to depict a model of TP53 -mediated transformation in myeloproliferative neoplasms in which inflammatory signaling leads to suppression of wild-type and MPN cells while giving a fitness advantage to TP53 [mutated] cells with leukemic stem-cell properties. From our study we hope to find this is applicable to many other cancer types,” said Rodriguez-Meira at the ASH session.
Single-cell multi omics analysis in a small patient cohort can theoretically be used to derive the gene signature that is highly relevant in much larger patient cohorts.

Othman Al-Sawaf MD PhD, a hematologist from University Hospital of Cologne, presents early data from the CLL17 international phase three trial at ASH 2025. The findings indicate that fixed-duration treatment with venetoclax plus obinutuzumab or venetoclax plus ibrutinib is non-inferior to continuous ibrutinib for patients with previously untreated chronic lymphocytic leukemia, potentially becoming the preferred treatment.

Dr. Juan Du presented early phase one study findings at ASH 2025, detailing a novel dual-targeted FasTCAR-T therapy for newly diagnosed multiple myeloma. The study demonstrated deep, durable responses in patients using the BCMA and CD19-targeting CAR T-cell platform, GC012F/AZD0120. These promising results, consistent across all dose groups, highlight a highly favorable safety profile and potential for patients, including those with high-risk features and transplant-ineligible individuals.

This podcast episode, recorded at ASH 2025, features an interview with María-Victoria Mateos MD PhD, who discusses groundbreaking findings from the Majestec-3 study. The study highlights unprecedented survival benefits with the BCMA/CD3 bispecific antibody teclistamab. In patients with relapsed or refractory multiple myeloma, adding teclistamab to standard second-line therapies significantly improved progression-free and overall survival.
