A Study of the Hsp90 Inhibitor AUY922 Plus Capecitabine for the Treatment of Patients With Advanced Solid Tumors

Study Overview
=================
Brief Summary
-----------------
The investigators propose this Phase I trial of the combination of AUY922 and capecitabine to determine the maximum tolerated dose (MTD) in patients with advanced solid tumors. This combination treatment has potential applicability in tumor types where capecitabine or fluorouracil is a treatment option, including colorectal and breast cancer.

Women of childbearing potential must use effective birth control measures during treatment and during the 6 months following completion of study treatment. If a woman becomes pregnant or suspects she is pregnant while participating in this study, she must agree to inform her treating physician immediately. Must be ≥18 years of age. Patients must be accessible for treatment and follow-up. Patients must be able to understand the investigational nature of this study and give written informed consent prior to study entry. Exclusion Criteria: Untreated CNS metastases. Patients with treated CNS metastases may be enrolled, provided the patient is asymptomatic, and the patient does not require antiepileptic drugs or steroids as treatment for the CNS metastases. Treatment with therapeutic doses of coumarin-type anticoagulants (maximum daily dose of 1 mg allowed for port line patency permitted). Impaired cardiac function with any one of the following: History (or family history) of long QT syndrome Mean QTc ≥450 msec on baseline ECG History of clinically manifested ischemic heart disease (i.e. myocardial infarction and/or unstable angina) ≤6 months prior to study start History of heart failure or left ventricular (LV) dysfunction (LVEF ≤45%) by MUGA or ECHO Clinically significant ECG abnormalities including 1 or more of the following: left bundle branch block (LBBB), right bundle branch block (RBBB) with left anterior hemiblock (LAHB). ST segment elevation or depression > 1mm, or 2nd (Mobitz II), or 3rd degree AV block. History or presence of atrial fibrillation, atrial flutter or ventricular arrhythmias including ventricular tachycardia or Torsades de Pointes Other clinically significant heart disease (e.g. congestive heart failure, uncontrolled hypertension, history of labile hypertension, or history of poor compliance with an antihypertensive regimen) Clinically significant resting bradycardia (< 50 beats per minute) Patients who are currently receiving treatment with any medication which has a relative risk of prolonging the QTcF interval or inducing Torsades de Pointes and cannot be switched to an alternative drug or discontinued prior to commencing AUY922 (see Appendix D). Obligate use of a cardiac pacemaker Impairment of gastrointestinal function or gastrointestinal disease that in the opinion of the Investigator may significantly alter the absorption of study drugs (e.g., Crohn's disease, ulcerative disease, uncontrolled vomiting, diarrhea, or malabsorption syndrome). Patients with known diagnosis of human immunodeficiency virus (HIV), hepatitis C virus, or acute or chronic hepatitis B infection. Concurrent severe, intercurrent illness including, but not limited to, ongoing or active infection, or psychiatric illness/social situations that would limit compliance with study requirements. Women who are pregnant (positive pregnancy test) or lactating. Any condition that would prevent patient comprehension of the nature of, and risk associated with, the study, and the inability to comply with study and/or follow-up procedures.

| --- | --- | --- |
| Drug Related Toxicities | To evaluate the drug related toxicities associated with different doses of the drugs used in this regimen. | 18 months | 
| Preliminary Efficacy Assessment: Response Rate (RR) | Response Rate (RR) is defined as the total number of patients with Complete Response (CR) or Partial Response (PR) as defined in RECIST v2. CR is defined as the dissappearance of all target lesions, disappearance of all non-target lesions and normalization of tumor markers. PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. | 18 months |
