Antibody-drug conjugates (ADCs) combine the specificity of monoclonal antibodies with biologically active cytotoxic molecules or drugs. As such, they can deliver cytotoxic agents specifically at the tumour site in a way that minimises systemic exposure and its associated toxicity. As of 2001, four ADCs have been approved by the European Medicines Agency for multiple human malignancies: gemtuzumab ozogamicin, brentuximab vedotin, trastuzumab emtansine, and inotuzumab ozogamicin. In addition to this, several new promising agents are under development. Although ADCs represent a new, effective class of therapeutics, the selection of the appropriate cytotoxin and linker remains challenging and systemic toxicity and rapid clearance should be monitored carefully. This review gives an overview on the safety and efficacy of ADCs in the treatment of haematological malignancies.

On Saturday, May 25th 2019, the Belgian Hematology Society (BHS) organised the first BHS patient network meeting in Brussels. Patients with lymphoma, chronic and acute leukaemia, myeloma, sickle cell disease and myeloproliferative neoplasms, their family members and friends were all welcome. The goal of this symposium was to discuss the role of patient organisations, summarise the latest advances in treatment of the different haematological malignancies and address the affordability of health care and the role of the government. Professor Rik Schots, head of the clinical haematology department at Brussels University Hospital, introduced the patients to haematology and the work of the BHS.

In addition to the long list of abstracts dedicated to malignant haematology, EHA 2019 also featured several sessions dedicated to benign haematological abnormalities. Results from the Northstar clinical trial program highlighted the efficacy of LentiGlobin gene therapy in transfusion-dependant β-thalassaemia. The BELIEVE study showed that Luspatercept treatment was associated with increased HbF in patients with red blood cell (RBC) transfusion dependent (TD) β-thalassaemia in both responders and non-responders. With respect to paroxysmal nocturnal haemoglobinuria, ravulizumab (a novel C5 complement inhibitor) and ACH-4471 (an inhibitor of factorD, a highly specific serine protease that cleaves factor B) proved to be promising new drugs. Finally, long term inhibition of complement C1s with the humanized monoclonal antibody sutimlimab can be a new strategy in treating patients with cold agglutinin disease.
