Study to Assess Biomarkers in Patients With Resectable Oral Cavity Cancer Randomized to Receive Preoperative Treatment

This is an interventional treatment trial for Oral Cavity Cancer focused on measuring Oral cavity cancer, No prior treatment Read More

Inclusion Criteria:

• Signed, voluntary informed consent provided
• Willing and able to comply with scheduled visits, treatment plan, tests, other study procedures
• Patient must be diagnosed with histologically confirmed oral cavity squamous cell carcinoma (OCC) (lip, floor of mouth, anterior 2/3 tongue, buccal mucosa, upper and lower gingiva, hard palate and retromolar trigone) considered resectable (T1-4a, N0-2, M0; (without distant metastases)) for whom surgical resection of tumor is planned. Patients with distant metastatic disease or diagnosis of SCCHN may not be enrolled
• Must be able to provide a fresh tumor biopsy prior to randomization for histopathological and biomarker evaluation. No anti-neoplastic treatment allowed between obtaining baseline tumor specimen and randomization. Patients who decline an in-house fresh pre-treatment tumor biopsy must give consent to provide a tumor block from an existing diagnostic primary tumor biopsy completed within 90 days of enrolment
• Prior treatment with agents targeted to epidermal growth factor receptor is not allowed.
• No prior chemotherapy or radiotherapy (to primary site/nodes).
• Patient must not have received prior anti-neoplastic treatment within past 2 years
• Any treatment-related acute toxicity, including laboratory abnormalities, must have recovered to CTCAE Grade 1 (v.4.0) or baseline, except toxicity not considered a safety risk.
• ECOG performance status of 0-2.
• Patient must have adequate organ function as determined by the following criteria:
• Serum creatinine ≤ 1.5 ULN or a calculated creatinine clearance of ≥ 50 mL/min
• Absolute neutrophil count ≥ 1.5 x 109/L
• Leukocytes > 3.0 x 109/L
• Hemoglobin > 80 g/L
• Platelets > 100 x 109/L
• Total bilirubin < ULN
• AST (SGOT) and ALT (SGPT) < 2.5 x ULN
• 12-Lead ECG with normal tracing, or clinically non-significant changes that do not require medical intervention
• QTc interval < 470 msec, and without history of Torsades de Pointes or other symptomatic QTc abnormality
• A normal LVEF of >50% as measured by ECHO or MUGA within 4 weeks prior to start of study treatment will be required for all patients

Exclusion Criteria:

• Patients who require segmental mandibulectomy for surgical resection of oral cavity tumor will not be enrolled
• Primary site of head and neck carcinoma in nasopharynx, skin, or unknown
• Prior or concurrent radiation therapy to tumor at site of planned resection
• Any clinically significant gastrointestinal abnormalities, which may impair intake, transit or absorption of PF-00299804
• Requirement for treatment with drugs that are highly dependent on CYP2D6 for metabolism since PF-00299804 is a potent CYP2D6 inhibitor in in vitro assays
• Patients currently taking drugs that have a risk of causing Torsades de Pointes
• Any acute or chronic medical, psychiatric condition or laboratory abnormality that could increase the risk associated with trial participation or trial drug administration or could interfere with interpretation of trial results and, in the judgment of the investigator, would make the patient inappropriate for entry in the trial
• Other serious uncontrolled medical disorder or active infection that would impair the ability to receive study treatment as determined by investigator
• Dementia or significantly altered mental status that would limit the ability to obtain informed consent and compliance with the requirements of this protocol
• Patients breastfeeding or pregnant are excluded. All female patients with reproductive potential must have a negative pregnancy test within 72 hours prior to treatment.
• Patients of reproductive potential or their partners must agree to use effective contraception while receiving trial treatment and for at least 3 months thereafter.
• Current enrollment in another therapeutic clinical trial
• Inability/lack of willingness to comply with visits, treatment plans, protocol assessments or laboratory tests
