Notes

Cladribine (purine analog) is profoundly lymphotoxic; per NCCN-SM: HBV/HCV/HIV screen mandatory before cytoreductive therapy. AASLD-HBV 2024 mandates entecavir or TAF prophylaxis for HBsAg+ on lymphocyte- depleting therapy through 12 months post-completion. Direction HOLD on cytoreduction until prophylaxis underway. STUB — requires clinical co-lead signoff.
