Study Details

Study Description

Brief Summary

This is a study to assess how much of the investigational drug, PF-00298804, is in the blood stream over a period of time (called pharmacokinetic tests or PK) in patients with locally advanced head and neck squamous cell carcinoma who have a (gastrojejunostomy) feeding tube.

Condition or Disease	Intervention/Treatment	Phase
Head and Neck Squamous Cell Carcinoma	Drug: PF-00299804	N/A

Detailed Description

This is a single arm pharmacokinetic assessment study conducted at Princess Margaret Hospital in which eligible patients will be enrolled successively to receive a single dose of PF-00299804 in an open-labelled, unblinded manner. All patients will receive 45 mg of PF-00299804 via Gastrostomy (GT) once only on an empty stomach (i.e. 2 hours before or after oral food intake or GT feeds (food intake of less than 500 calories permitted)) as an inpatient. All patients will be admitted for an overnight inpatient stay (approximately 24 hours) to facilitate pharmacokinetic assessment. There will be no dose reductions or modifications. Blood sampling for pharmacokinetics will occur on day 1 immediately prior to the dose of PF-00299804 (t=0), then at t=30 minutes, t=1 hour, t=2 hours, t=3 hours, t=4 hours, t=6 hours, t=12 hours, t=24 hours, t=48 hours, t=72 hours, t=96 hours, t=144 hours, t=168 hours, t=192 hours, and t=216 hours.

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Signed, voluntary informed consent provided
Willing and able to comply with visits, treatment plan, pharmacokinetics, tests, other procedures
Confirmed SCCHN. Other primary sites of head and neck carcinoma: nasopharynx, skin, maxillary sinus or unknown primary, are allowed
Must have functioning gastrojejunostomy tube
May be receiving concurrent chemoradiation, radiation alone or recently completed surgery for locally advanced disease
Prior treatment with agents targeted to epidermal growth factor receptor not allowed.
Any treatment-related toxicity, including laboratory abnormalities, must have recovered to CTCAE Grade 2 (v.4.0) or baseline, except toxicity not considered safety risk. Chronic dysphagia, xerostomia or other local effect from prior surgery or radiation will not be considered exclusion criterion if stable for ≥ 3 months.
ECOG performance status 0-2
Must have adequate organ function determined by: Serum creatinine ≤ 1.5 ULN (upper limit of normal) or calculated creatinine clearance of ≥ 50 mL/min using the formula: Creatinine clearance = [(140-age) x wt (kg) x Constant] / creatinine (µmol/L) [Constant = 1.23 for men; 1.04 for women]. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L; Leukocytes ≥ 3.0 x 109/L; Hemoglobin ≥ 80 g/L (or > 8 g/dL); Platelets ≥ 100 x 109/L. Total bilirubin ≤ ULN; AST (SGOT) and ALT (SGPT) ≤ 2.5 x ULN. 12-Lead electrocardiogram (ECG) with normal tracing, or clinically non-significant with no medical intervention; QTc interval ≤ 470 msec, without history of Torsades de Pointes or other QTc abnormality

Exclusion Criteria:

Cannot be enrolled on another clinical trial
Prior investigational drug therapy within 30 days or 5 half-lives preceding first dose of study drug (whichever longer)
Requirement for drugs highly dependent on CYP2D6 for metabolism since PF-00299804 is a potent CYP2D6 inhibitor
Patients currently taking drugs with risk of Torsades de Pointes
Any acute/chronic medical, psychiatric condition or laboratory abnormality that could increase risk of participation, trial drug administration or interfere with interpretation of trial results and, investigator feels, would make patient inappropriate for entry. Including: History of interstitial lung disease; Uncontrolled hypertension, unstable angina, myocardial infarction, symptomatic congestive heart failure within past year, uncontrolled cardiac arrhythmia, diagnosed/suspected congenital long QT syndrome; history of stroke, deep vein thrombosis, or stable for 6 months without requiring antiarrhythmics/significant change in medical management; Active bacterial, fungal or viral infection including hepatitis B/C, and human immunodeficiency virus. Testing not required at baseline with no symptoms of infection. History of significant bleeding disorder, or concurrent medications that investigator feels may lead to unacceptable coagulation during perioperative interval, including: congenital bleeding disorders; acquired bleeding disorder within a year
Other serious uncontrolled medical disorder or active infection that would impair ability to receive study treatment as determined by investigator
Dementia or altered mental status that would limit ability to obtain informed consent and compliance with requirements of the protocol
Patients breastfeeding or pregnant are excluded. Those with reproductive potential must have negative pregnancy test within 72 hours of treatment. Patients of reproductive potential include any female who has experienced menarche and who has not undergone successful surgical sterilization, or is not postmenopausal. Patients of reproductive potential/partners must agree to effective contraception while receiving trial treatment and for at least 3 months after. Effective contraception will be judgment of principal investigator or designate
Inability/lack of willingness to comply with visits, treatment plans, assessments or tests
