Jorge Castillo, MD, shares data on an all-oral, non-chemo, fixed-duration regimen for Waldenström macroglobulinemia using pirtobrutinib and venetoclax. The combination delivered rapid, profound and 100% overall responses with manageable side effects and high rate of deep responses. #ASH25

🩸📖 NEJM 2003: CLOT trial - 676 patients w/ cancer-associated thrombosis (CAT) - Dalteparin vs warfarin. Dalteparin dose: 200 IU/kg sc daily ×1/12 → 150 IU/kg daily ×5/12 (total 6 months). Outcome: ↓ recurrent VTE; no ↑ major bleed in the group who received dalteparin. #hemesky #thrombosis #medsky

CARAVAGGIO 2020 (1,170 pts): Apixaban vs dalteparin for cancer VTE. Recurrent VTE 5.6 % vs 7.9 % (non-inf). Major bleed 3.8 % vs 4.0 %; no extra GI bleed. Bottom line: apixaban noninferior to dalteparin without increase in major bleeding in cancer-associated VTE. #medsky #hemesky #thrombosis
