A Phase I Study of the Hsp90 Inhibitor AUY922 Plus Capecitabine for the Treatment of Patients With Advanced Solid Tumors
1. Histologically confirmed metastatic or unresectable solid tumor malignancy that is
incurable and for which capecitabine is clinically appropriate.
2. Patient must be ≥4 weeks from administration of last dose of cancer therapy
(including radiation therapy, biologic therapy, hormonal therapy or chemotherapy).
Patients who received a small molecule targeted therapy as part of their first line
treatment regimen must be ≥4 weeks or ≥5 half lives from administration of last dose
whichever is shorter. The patient must have recovered from or come to a new chronic
stable baseline from all treatment-related toxicities.
3. Eastern Collaborative Oncology Group (ECOG) performance status 0 to 1 (see Appendix
4. Life expectancy of ≥3 months.
5. At least one unidimensional measurable lesion definable by MRI or CT scan. Disease
must be measurable per Response Evaluation Criteria in Solid Tumors (RECIST) version
1.1 criteria (see Section 9).
6. Normal bone marrow function defined as:
- Absolute neutrophil count (ANC) ≥1500/μL
- Hemoglobin (Hgb) ≥9 g/dL
- Platelets ≥100,000/μL
7. Adequate hepatic function defined as:
- AST or ALT and alkaline phosphatase (ALP) must be ≤3 x ULN, or ≤5 x ULN in
patients with liver metastases
- Total bilirubin ≤1.5 x the institutional ULN
8. Renal function defined as:
• Serum creatinine ≤1.5 x ULN or 24-hour creatinine clearance ≥40 mL/min
9. Normal electrolytes defined as:
- Phosphorous ≥ LLN
- Magnesium ≥ LLN
10. Women of childbearing potential (WOCBP) must have a negative serum or urine
pregnancy test performed within 7 days prior to start of treatment. 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.
11. Must be ≥18 years of age.
12. Patients must be accessible for treatment and follow-up.
13. Patients must be able to understand the investigational nature of this study and give
written informed consent prior to study entry.
1. 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.
2. Treatment with therapeutic doses of coumarin-type anticoagulants (maximum daily dose
of 1 mg allowed for port line patency permitted).
3. 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
4. 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
5. Patients with known diagnosis of human immunodeficiency virus (HIV), hepatitis C
virus, or acute or chronic hepatitis B infection.
6. 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.
7. Women who are pregnant (positive pregnancy test) or lactating.
8. 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
