Dear Colleagues,

The ASH Annual Meeting and Exposition is the premier event for presentation of novel data on malignant and non-malignant hematologic diseases, attracting up to 30,000 specialists from all over the world. The 62nd ASH Annual Meeting was planned to be held on December 5–8, 2020 in ­San Diego, California, but due to the COVID-19 pandemic had been trans­formed to an all-virtual event. Attendees had access to thousands of scientific abstracts highlighting cutting-edge research in hematology. This publi­cation summarizes work presented in the field of B-cell malignancies with a focus on targeted therapies.

Inhibition of the Bruton’s tyrosine kinase (BTK) has been implemented as a mainstay of treatment in various types of hematologic malignancies, including Waldenström’s macroglobulinemia, chronic lymphocytic leukemia, marginal zone lymphoma, and mantle cell lymphoma. Later-generation BTK inhibitors designed to achieve optimized selectivity offer advantages with respect to tolerability and efficacy compared to first-generation BTK inhibition. Benefits have been observed with these agents irrespective of factors such as pre­treatment or cytogenetic risk. 

Progress is also ongoing regarding other drug classes such as PI3Kδ inhibitors and anti-CD20 antibodies that complement the armamentarium available for the treatment of various B-cell malignancies. Immune checkpoint inhibition might also play a role in the future, although a variety of inhibitory receptors apart from PD-1 and PD-L1 are still awaiting investigation in terms of their clinical usefulness as targets for drug therapy. 

Naturally, combinations are a major area of research given the importance of achieving deep remission that allows for long-lasting disease-free survival. The wide range of drugs already established in the field of hematologic diseases enables the assessment of new regimens that might represent a major step forward in terms of patient life expectancy and quality of life.
