A Randomized Phase Ii Study Of Az2014 Versus Everolimus In Patients With Vegf Refractory Metastatic Clear Cell Renal Cancer (Mrcc).

409 Background: Dual TORC1 and 2 inhibitors such as AZD2014 have theoretical advantages over isolated TORC1 inhibitors such as everolimus in the treatment of mRCC. In this study we compare the activity of these drugs in patients with vascular endothelial growth factor (VEFG) refractory mRCC. Methods: Patients with measurable VEGF refractory mRCC were randomised (1:1) to AZD2014 or everolimus stratified by MSKCC prognostic score and 1st line targeted therapy. Progression free survival (PFS) measured by RECIST v1.1 was the primary endpoint. Adverse events (AE) (CTCAE v4.03), response rates (RR) and overall survival (OS) were reported. This was an investigator led study and had appropriate ethical approval. Results: The study was stopped early (May 2014) with the recommendation of the IDMC. At this point 48 patients were recruited and 40 (AZD2014 23 :everolimus 17) patients were assessable for efficacy. Patient’s demographics were similar in the 2 groups. The median PFS was shorter for AZD2014 than everolimu...
