Support for potential extra travelling costs during the transition period when working at the Oss site About AstraZeneca Oncology R&D, Amsterdam At AstraZeneca Amsterdam, we bring together two research groups, in haemato-oncology and next-generation cell therapy research. Together, they form our Oncology R&D hub in the Netherlands, working closely with colleagues in the US, Canada, Spain and the UK, to develop innovative treatments for patients with cancer. Our haematology R&D group was born as Acerta Pharma, one of the Netherlands’ greatest biotech success stories. Our small-molecule BTK inhibitor has been approved by both the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of Chronic Lymphocytic Leukaemia (CLL) and Mantle Cell Lymphoma (MCL). In Amsterdam approximately 100 colleagues continue the development of new therapies for haematological malignancies under the AstraZeneca brand name. AstraZeneca’s Cell Therapy R&D team focuses on developing next-generation T-cell receptor (TCR) therapies targeting neoantigens in solid tumours. With a team of around 75 scientists, we work on both fully individualised and shared neo-antigen approaches, with the aim of improving outcomes for patients with cancer. Our oncology research and development hub is anchored by our new state-of-the-art laboratories in OneHelix and the adjacent Plus Ultra Amsterdam building, both located on the Amsterdam University Medical Centre (Amsterdam UMC) campus. Our hub is firmly positioned at the heart of the Dutch research community network, creating new opportunities for our people, our science, and the patients we work to transform outcomes for.
