AstraZeneca advances its ambition to redefine haematology care with new data from its diverse pipeline and portfolio at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition, 6-9 December 2025.

This year's ASH congress will feature the Company's largest presence to date, with 65 abstracts across eight approved and investigational medicines, including 15 oral presentations.

Key presentations include:

• Phase I trial of surovatamig: Updated results at three-year follow up from the ongoing first-in-human trial of surovatamig, a CD19xCD3 T-cell engager, in relapsed/refractory (R/R) follicular lymphoma (FL) (Oral Abstract #1005).
• DURGA-1 Phase Ib/II study: Initial data for AZD0120 in patients with R/R multiple myeloma (MM). AZD0120 is an investigational BCMAxCD19 chimeric antigen receptor T-cell (CAR T) therapy (Oral Abstract #269).
• ECHO Phase III trial: Results after 50 months of follow up evaluating Calquence (acalabrutinib) plus bendamustine and rituximab in the first-line treatment of mantle cell lymphoma (MCL) (Oral Abstract #885).
• ALXN1210-TMA-314 Phase III trial: Additional results from the open-label trial evaluating Ultomiris (ravulizumab) in paediatric patients with haematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA) (Oral Abstract #1052).

Anas Younes, Senior Vice President, Haematology R&D and Chief Medical Officer, AstraZeneca, said: "We are advancing a broad pipeline of investigational therapies with the potential to redefine patient care across multiple types of blood cancer. At ASH, we are sharing meaningful progress with early efficacy and safety data for AZD0120, our first cell therapy, in multiple myeloma, and for surovatamig, a novel T-cell engager, in B-cell malignancies."

Christophe Hotermans, Senior Vice President, Head of Global Medical Affairs, Alexion, said: "At ASH, we look forward to demonstrating how pioneering science can drive meaningful advances for people living with rare haematologic conditions. New data on Ultomiris, including Phase III results in paediatric patients with HSCT-TMA, will show clinically meaningful overall survival and improved outcomes, highlighting our ongoing pursuit to realise the full potential of our medicines and their impact on treating rare conditions."

Additional highlights include:

• SYRUS Phase I/II trial: Updated safety and efficacy data for surovatamig in adolescent and adult patients with R/R B-cell acute lymphoblastic leukaemia (Abstract #3345)
• Phase I trial of surovatamig: Initial efficacy and safety data for surovatamig in R/R diffuse large B-cell lymphoma (Abstract #5514)
• AZD0120: Follow-up data from two investigator-initiated trials (IIT) in China evaluating AZD0120 as a first-line therapy in high-risk, newly diagnosed MM (Oral Abstract #258).

• TrAVeRse Phase II trial: Preliminary results evaluating Calquence plus venetoclax and rituximab in treatment-naïve MCL patients (Oral Abstract #884).
• AMPLIFY Phase III trial: Exploratory analyses supporting the safety and efficacy profile of Calquence in first-line chronic lymphocytic leukaemia, with new subgroup data evaluating the impact of prognostic mutations on clinical outcomes (Poster Abstract #3898).
• ALPHA Phase III trial: Sub-analysis of results evaluating Voydeya (danicopan) as add-on to Ultomiris or Soliris (eculizumab) in adults with paroxysmal nocturnal haemoglobinuria (PNH) and clinically significant extravascular haemolysis, including in patients with advanced age (Oral Abstract #949).

• Ultomiris: Real-world evidence highlighting the impact of Ultomiris in certain patient subgroups across approved indications, including in pregnant patients (Poster Abstracts #6238 and #4458).

Notes

AstraZeneca in haematology
AstraZeneca is pushing the boundaries of science to redefine care in haematology. Our goal is to help transform the lives of patients living with malignant, rare and other related haematologic diseases through innovative medicines and approaches that are shaped by insights from patients, caregivers and physicians. 

In addition to our marketed products, we are spearheading the development of novel therapies designed to target underlying drivers of disease across multiple scientific platforms. Our acquisitions of Alexion, with expertise in rare, non-malignant blood disorders, and Gracell Biotechnologies Inc., pioneers of autologous cell therapies, expand our haematology pipeline and enable us to reach more patients with high unmet needs through the end-to-end discovery, development and delivery of novel therapies.

AstraZeneca in cell therapy
AstraZeneca's ambition is to realise the full potential of cell therapies. It is focused on empowering the immune system to attack cancers, reset the underlying drivers of immune-mediated diseases to return patients to health, and provide transformative solutions with curative potential for people living with rare diseases. To achieve this, the Company is building world-class cell therapy capabilities and advancing a broad pipeline of cell therapies, enabled by technologies including chimeric antigen receptor T-cells (CAR T), T-cell receptor therapies (TCR T) and CAR T regulatory (CAR Tregs) cells.

AstraZeneca in oncology
AstraZeneca is leading a revolution in oncology with the ambition to provide cures for cancer in every form, following the science to understand cancer and all its complexities to discover, develop and deliver life-changing medicines to patients.
