A Phase 2 Study of Sunitinib in Recurrent and/or Metastatic Adenoid Cystic Carcinoma of the Salivary Glands

This is an open-label phase II study of sunitinib malate in patients with recurrent and/or
metastatic adenoid cystic carcinomas (ACC) of major or minor salivary gland origin.
Sunitinib is a novel, multi-targeted small molecule inhibitor of the receptor tyrosine
kinases (RTKs), including vascular endothelial growth factor receptors (VEGFs), platelet
derived growth factor receptors (PDGFRs) and stem cell factor receptor (KIT), that are
involved in tumour proliferation and angiogenesis. VEGF expression has been associated
clinically with disease prognosis in many different types of cancers and a number of studies
have suggested that VEGF may play an important role in the pathogenicity of ACC. Sunitinib
is expected to inhibit PDGF- and VEGF-driven angiogenesis and, as a consequence, limit solid
tumour growth.This study will determine the anti-tumour activity of sunitinib in ACC of the
salivary glands using objective response rates (partial and complete responses) as its
primary objective.

Inclusion Criteria:

- Patients must have histologic or cytologic adenoid cystic carcinomas of major or
minor salivary gland origin.

- Patients must have recurrent and/or metastatic disease that is progressive and not
amenable to surgery or curative radiotherapy occurring within 6 months of study

- at least a 20% increase in radiologically or clinically measurable disease;

- appearance of any new lesions or

- deterioration in clinical status

- Patients must have measurable disease, at least one lesion that can be accurately
measured in at least one dimension as >20 mm with conventional techniques or as >10
mm with spiral CT scan.

- Patients with prior therapy with at least a 4 weeks' interval between any
chemotherapy (6 weeks for nitrosoureas or mitomycin C), radiotherapy or surgery and
study enrollment. Exceptions may be made for low dose, non-myelosuppressive

- Patients must be 18 years of age or older.

- Life expectancy of greater than 12 weeks.

- Patients must have normal organ and marrow function as defined below:

- leukocytes >3,000/μL

- absolute neutrophil count >1,500/μL

- platelets >100,000/μL

- total bilirubin within normal institutional limits

- AST(SGOT)/ALT(SGPT) ≤2.5 X institutional upper limit of normal

- amylase/lipase within normal institutional limits

- creatinine within normal institutional limits

- creatinine clearance >60 mL/min/1.73 m2 for patients with creatinine levels
above institutional normal

- Cardiac ejection fraction within the institutional range of normal as measured by
ECHO or MUGA scan.

- Patients must have QTc < 500 msec on baseline ECG.

- Patients with New York Heart Association (NYHA) Class II cardiac function:

- with a history of Class II heart failure who are asymptomatic on treatment

- with prior anthracycline exposure

- who have received central thoracic radiation that included the heart in the
radiotherapy port.

- Women of child-bearing potential and men must agree to use adequate contraception
(hormonal or barrier method of birth control or abstinence) prior to study entry and
for the duration of study participation.

- Ability to understand and the willingness to sign a written informed consent

Exclusion Criteria:

- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for
nitrosoureas or mitomycin C) prior to entering the study or those who have not
recovered from adverse events due to agents administered more than 4 weeks earlier.
At least 4 weeks must have elapsed since any major surgery.

- Patients receiving any other investigational agents.

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to sunitinib.

- Patients with QTc prolongation or other significant ECG abnormalities.

- Patients with poorly controlled hypertension.

- Patients who require use of therapeutic doses of coumarin-derivative anticoagulants
such as warfarin, although doses of up to 2 mg daily are permitted for prophylaxis of
thrombosis. Note: Low molecular weight heparin is permitted provided the patient's PT
INR is <1.5.

- Patients with any condition that impairs their ability to swallow and retain
sunitinib tablets.

- Patients with any of the following conditions:

- Serious or non-healing wound, ulcer, or bone fracture.

- History of abdominal fistula, gastrointestinal perforation, or intraabdominal
abscess within 28 days of treatment.

- Any history of cerebrovascular accident or transient ischemic attack within 12
months prior to study entry.

- History of myocardial infarction, cardiac arrhythmia, stable/unstable angina,
symptomatic congestive heart failure, or coronary/peripheral artery bypass graft
or stenting within 12 months prior to study entry.

- History of pulmonary embolism within the past 12 months.

- Class III or IV heart failure as defined by the NYHA.

- Patients taking medications that are potent inducers or inhibitors of the CYP3A4
liver enzyme (unless deemed acceptable by the Principal Investigator).

- Patients with a pre-existing thyroid abnormality who are unable to maintain thyroid
function in the normal range with medication.

- Patients with known brain metastases.

- Patients with uncontrolled intercurrent illness including, ongoing or active
infections or psychiatric illness/social situations that would limit compliance with
study requirements.

- Pregnant women. Breastfeeding should be discontinued if the mother is treated with

- HIV-positive patients on combination antiretroviral therapy

- Patients taking any of the medications that may cause QTc prolongation unless the
required washout period has been met.

Type of Study:


Study Design:

Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:
