A Study of AUY922 for GIST(Gastrointestinal Stromal Tumor) Patients
Study Details
Study Description
Brief Summary
A Phase II Study of AUY922, Novel HSP Inhibitor, in Patients with Advanced GIST Failed to or Intolerance of Imatinib and Sunitinib Therapy
Primary endpoint:
•The primary endpoint of this study is to assess disease control rate (complete response + partial response + stable disease≧4 months) of AUY922 in patients with advanced GIST failed to imatinib and sunitinib
Secondary endpoints:
-
To determinate the objective response rate (ORR, complete response + partial response)
-
To determinate the time to tumor progression (TTP)
-
To evaluate the safety and toxicity profiles of AUY922
-
To evaluate the pharmacokinetics profile of AUY922 in Taiwan GIST population
-
To access the pharmacodynamic effect of AUY922 on HSP client proteins in blood and tumor if feasible , i.e. HSP70, in Taiwan GIST population
-
To access the tissue biomarkers pre-treatment and 4wks post treatment if feasible, i.e. HSP70, c-KIT, PDGFRA mutation, ...etc in Taiwan GIST population
Exploratory endpoints:
•PET imaging; sSUVmax

Detailed Description
This is an open-label; pharmacokinetic and pharmacodynamic phase II study of AUY922 in patients with advanced GIST failed to or intolerance of imatinib and sunitinib therapy. AUY922 is a novel HSP90 inhibitor and will be administered at dose of 70 mg/m2 i.v. infusion on D1 every week. The Simon one sample two-stage minimax design was used with 15 suitable patients to be accrued to the first stage. If at least two patients meet our primary endpoint (complete response＋partial response＋stable disease≧4 months), an additional 10 patients would be recruited to the second stage. AUY922 would be considered active in this patient population, if there were more than 5 cases of non-progressive disease in the total cohort of 25 patients.

-
Life expectancy ≥ 4 months
-
At least 4 weeks apart from prior systemic (including chemotherapy, approved targeted therapy or investigational agent) and surgical treatment, and recovery from all prior treatment-related toxicity to grade < 1 according to Common Terminology Criteria for Adverse Events (CTCAE) v4.0.
-
With adequate organ and marrow function as defined below:
-
WBC ≥ 3.00 × 103/ mm3 and absolute neutrophil count ≥ 1.50 × 103/ mm3
