In this week’s episode we discuss the role of allogeneic transplant in adult patients with Philadelphia chromosome-positive acute lymphoblastic leukemia. In a retrospective study, transplant provided no survival benefit in patients with rapid and deep responses to induction therapy that included BCR-ABL1 inhibitors. Up next, we discuss the evidence for an increased risk of ventricular arrythmias with use of acalabrutinib, which has emerged as a class effect of Bruton tyrosine kinase inhibitors. Lastly, we examine a novel, alloantigen-specific model to test the efficacy of a prophylactic treatment strategy for preventing fetal/neonatal alloimmune thrombocytopenia.
