A phase II study of cixutumumab (IMC-A12, NSC742460) in advanced hepatocellular carcinoma.

ABSTRACT:

Background & aims

IGF-IR is implicated in hepatic carcinogenesis. This and preliminary evidence of biological activity of anti-IGF-1R monoclonal antibody cixutumumab in phase I trials prompted this phase II study.

Methods

Patients with advanced HCC, Child-Pugh A-B8, received cixutumumab 6mg/kg weekly, in a Simon two-stage design study, with the primary endpoints being 4-month PFS and RECIST-defined response rate. Tissue and circulating markers plus different HCC scoring systems were evaluated for correlation with PFS and OS.

Results

As a result of pre-specified futility criteria, only stage 1 was accrued: N=24: median age 67.5 years (range 49-83), KPS 80% (70-90%), 20 males (83%), 9 stage III (37%)/15 stage IV (63%), 18 Child-Pugh A (75%), 11 HBV (46%)/10 HCV (42%)/11
