"* Patients will receive HDMP + Rituximab for 1 cycle, followed by reassessment of Tumor Burden,~* If Tumor Burden classification is low after HDMP + Rituximab (lymph nodes \< 5cm in diameter AND absolute lymphocyte count \< 25k/uL), patients will initiate venetoclax dose ramp-up, with ramp-up schedule according to venetoclax package insert.~* Patients who still have a disease burden (lymphadenopathy \> 5 cm or ALC \> 25k/iL) that meets criteria for medium or high risk of TLS after 1 cycle of HDMP + Rituximab are given the option to repeat a 2nd cycle of HDMP + Rituximab prior to venetoclax dose ramp-up."
