Abstract Share this page

CVX-045 is produced by covalently attaching a thrombospondin 1 (TSP-1) mimetic comprising a peptidic sequence and a linker to the Fab binding site of a proprietary scaffold antibody. CVX-045 possesses the potency of the TSP-1-derived peptide, along with the advantageous pharmacokinetics of an antibody. Antitumor activity of CVX-045 was evaluated in human xenograft models alone and in combination with standard chemotherapies and targeted molecules. In A549 and A431 xenograft models, CVX-045 demonstrated significant (P < .05) antiangiogenic activity, reducing tumor microvessel density and increasing the levels of necrosis within treated tumors. In an HT-29 xenograft model, CVX-045 in combination with 5-fluorouracil significantly (P < .01) decreased tumor growth rate compared with vehicle, CVX-045, or 5-fluorouracil alone. Cotreatment of CVX-045 plus CPT-11 delayed progression of tumor growth from day 28 to 60. In contrast CVX-045 alone treatment did not delay the progression of tumor growth, and CPT-11 alone delayed progression of tumor growth to day 39. Cotreatment of CVX-045 with sunitinib extended the time to reach tumor load from day 26 to 40. In summary, CVX-045 exhibits significant antiangiogenic activity in several tumor models and enhances antitumor activity in combination with chemotherapy or targeted therapies. These data suggest future avenues for effective combination therapy in treating solid tumors. CVX-045 has recently completed a phase 1 trial in solid tumors where it has been well tolerated.
