GSK’s pazopanib hits endpoint
03.06.2013 - GlaxoSmithKline’s multi kinase blocker pazopanib has increased progression free survival in women with advanced ovarian cancer by 5.6 months.
At the ASCO meeting, the British drug major reported that the median time to disease progression under the VEGFR, PDGFR, c-KIT blocker post-surgery and chemotherapy was 17.9 months, compared with 12.3 months in patients receiving placebo. GSK announced that it will file an MAA in the US for pazopanib as first-in-class maintenance therapy after surgery and chemotherapy. In contrast to Europe where Roche’s bevacizumab is approved as maintenance therapy, there is no comparable treatment approved by the FDA.
91% of the 940 patients with advanced epithelial ovarian cancer had stage III/IV disease at diagnosis and no residual disease following surgery. While efficacy was shown, more serious adverse drug effects were observed in the pazopanib group (26%) than in the placebo arm (11%) of the study.
