Abstract | PURPOSE: METHODS: In vitro, human BCLs were cultured with CMC-544 or individual constituents of CHOP for inhibition of their growth. In vivo, immunocompromised mice with established BCL xenografts were administered CHOP, CVP or CMC-544 to monitor their survival and BCL growth. RESULTS: In vitro, CMC-544 was more potent in causing growth inhibition of various BCL than cyclophosphamide, doxorubicin, vincristine or dexamethasone. In vivo, treatment with CHOP or CVP inhibited growth of BCL xenografts for up to 40 days after which BCL relapsed. Tumor growth inhibition by CMC-544 (>100 days) lasted longer than that by CHOP or CVP. BCL xenografts that relapsed after the treatment with CHOP or CVP were far less responsive to CHOP or CVP re-treatment but regressed upon subsequent treatment with CMC-544. CVP could be co-administered with suboptimal doses of CMC-544, while CHOP could be administered on alternant days with CMC-544 to cause enhanced regression of established BCL xenografts. CONCLUSION: Preclinically, CMC-544 provides greater therapeutic benefit than CVP or CHOP against BCL xenografts. CMC-544 may also be co-administered with standard chemotherapeutic regimens in the treatment of B-NHL for superior anti- tumor activity.
