This feasibility study is designed as a side study to the multicenter, international phase I-II trial with HSP90 inhibitor AUY922 (protocol CAUY922A2101), as part of the biomarker assessment. In protocol CAUY922A2101, section 4, the design of this phase I-II trial is described (p37, 38). Briefly, a dose-escalation study is performed according to phase I design in adult patients with advanced solid malignancies. This part is followed by a dose-expansion study according to a phase II design. In the latter part, breast cancer patients are enrolled that are either refractory to hormone- or trastuzumab treatment (both treatment arms, n=40 patients), on the maximal tolerated dose of AUY922 based on the phase I part of the study. Patients with ER positive, hormone therapy refractory breast cancer, will receive a 89Zr-bevacizumab PET scan as part of the present side study protocol, which will be performed in collaboration with the Royal Marsden Hospital (United Kingdom).
To this end, a 89Zr-bevacizumab PET scan will be performed before (baseline) and during treatment with HSP90 inhibitor AUY922, as described below.
A minimum of six patients will be entered to evaluate whether the effect of HSP90 inhibition by AUY922 can be detected with a 89Zr-bevacizumab PET scan

- To evaluate the effect of HSP90 inhibition by AUY922 on VEGF by means of 89Zr-bevacizumab PET. [ Time Frame: 2 years ]Primary endpoint: measurement of decreased VEGF compared to baseline. A decline is defined as a decrease of at least 30% in mean Standardized Uptake Value (SUV) in a maximum of three lesions.
