Anyone else diagnosed with 'aCLL' - rare variation?

I was diagnosed with CLL in 2021 and put on 'watch and wait'. A swollen lymph node biopsy this year led to a finding of 'aCLL' which was described by my hematologist as being an accelerated or aggressive form of CLL. (Not the Richter Transformation, TG.) Because it is a relatively newly discovered subset of the disease, little is known about it, and I wonder if anyone else has had this diagnosis and if so how your doctor wants to manage it? Mine put me on a BTK inhibitor which I was unable to tolerate and we're currently in a holding pattern. Thanks and best wishes to us all.
