The Lymphoma Academic Research Organisation · Phase 3 active Small molecule

R-CHOP/R-HAD is a combination chemotherapy regimen that uses rituximab (an anti-CD20 monoclonal antibody) plus alternating cycles of CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) and HAD (high-dose cytarabine, doxorubicin, dexamethasone) to target B-cell lymphomas.

Mechanism of action

Rituximab binds to CD20 antigen on B-cell surfaces, triggering antibody-dependent cellular cytotoxicity and direct apoptosis. The alternating chemotherapy cycles (CHOP and HAD) provide intensive cytotoxic activity with different mechanisms and schedules to overcome chemotherapy resistance. This combination approach is designed to improve efficacy in aggressive lymphomas, particularly in younger or fit patients who can tolerate intensive treatment.
