The selective HDAC6 inhibitor 7b induced sustained α-tubulin acetylation at lower concentrations than ricolinostat or nexturastat A. 7b reduced primary CML PBMC viability while sparing healthy PBMCs and was active in vivo...ISR activation occurred downstream of the autophagy disruption: rapamycin attenuated ISR activation, whereas ATG7 silencing intensified ISR signaling and apoptosis...The combination elicited immunogenic cell death markers: calreticulin exposure, ATP and HMGB1 release, elevated TNF-α, and reduced IL-8. These findings identify HDAC6-driven autophagy as a therapeutically exploitable vulnerability in CML that, when combined with asciminib, triggers ISR-dependent immunogenic apoptosis.
Chronic lymphocytic leukaemia (CLL) most commonly transforms into aggressive lymphoma; development of chronic myeloid leukaemia (CML) in a patient with CLL should prompt evaluation for an independent myeloid clone rather than presumed transformation.Myeloid neoplasms in patients with CLL may arise from therapy-related leukemogenesis or divergent evolution from a shared hematopoietic progenitor, highlighting the importance of molecular characterization.Management of coexisting CLL and CML requires individualized risk-benefit assessment, particularly in elderly patients with prior solid tumours and immune dysfunction.

In patients experiencing failure of frontline therapy due to resistance or intolerance, multiple second- and third-line options are available, including second-generation TKIs, ponatinib, and asciminib, as well as novel investigational agents, including the ABL1 kinase domain inhibitors olverembatinib and ELVN-001 and the STAMP inhibitors TGRX-678 and TERN-701. In this review, we discuss the recent advances in the treatment of CML-CP and challenge some established management practices.
