Trial overview

Official title: PGx7592: Evaluation of the Effect of BIM Germline Variants on Pazopanib Efficacy in Patients with Cancer
Trial description: Pazopanib and sunitinib are anti-angiogenic, oral tyrosine kinase inhibitors (TKIs), both are approved for use in advanced or metastatic renal cell carcinoma (RCC). Pazopanib is also approved for use in advanced soft tissue sarcoma (STS), and sunitinib is approved for use in gastrointestinal stromal tumour and pancreatic neuroendocrine tumours. Currently, there is no validated biomarker that predicts response to treatment with either pazopanib or sunitinib.
A 2.9kb deletion polymorphism in the BIM gene was shown to be associated with resistance to gefitinib treatment in subjects with non-small cell lung cancer, and with resistance to imatinib treatment in subjects with chronic myeloid leukemia (Ng et al. Nat Med 2012; 18:521-8). This deletion has only been observed in individuals of East Asian descent. This pharmacogenetic (PGx) analysis will assess association between the BIM deletion and other putatively functional BIM polymorphisms and progression free survival (PFS), overall survival (OS) and best response in subjects received either pazopanib or sunitinib. The PGx analyses will using data from consented subjects in eight GSK clinical studies for advanced/metastatic RCC (VEG102616, VEG105192, VEG107769, VEG108844 and VEG113078), advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer (VEG110655, VEG114012 ), and advanced STS (VEG110727). The primary analysis will test association between the BIM deletion and PFS in pazopanib-treated subjects of East or South-East (E/SE) Asian ancestry. Secondary analyses will test association between 1) the BIM deletion with OS and best response in pazopanib- treated subjects of E/SE Asian ancestry; 2) the BIM deletion and efficacy endpoints in sunitinib-treated subjects of E/SE Asian ancestry; 3) other putatively functional BIM polymorphisms with efficacy endpoints in pazopanib- or sunitinib-treated subjects of all ancestries. Cox proportional hazards model will be used to assess the association of genotype with PFS and OS. Ordinal regression will be conducted for best response. Summary statistics from genotyping/indications groups will be meta-analyzed using the inverse variance method.
