AstraZeneca unveils 65 haematology abstracts at ASH 2025, including first cell therapy data

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).
