A Phase I, Open-Label, Randomized, Two Period Crossover Study to Investigate the Effects of GW679769 on the Pharmacokinetics of Docetaxel in Subjects With Cancer


Inclusion Criteria:



- Male or female

- 18 years of age

- A female is eligible to enter and participate in this study if she is of:

1. Non-child-bearing potential (i.e., physiologically incapable of becoming
pregnant), including any female who has had at least one of the following:

- Has had a hysterectomy, or

- Has had a bilateral oophorectomy (ovariectomy), or

- Has had a bilateral tubal ligation, or • Is considered post-menopausal
(defined as amenorrheic for ≥ 1 year) and having serum follicle stimulating
hormone (FSH) and serum estradiol concentrations consistent with
post-menopausal status.

2. Childbearing potential, has a negative serum pregnancy or negative urine
pregnancy test within 24 hours prior to administration of the first dose of
study medication and agrees to one of the following:

- Complete abstinence from sexual intercourse from two weeks prior to
administration of the first dose of investigational product until 30 days
after the final dose of study medication.

- Use double-barrier contraception (condom with spermicidal jelly, foam
suppository, or film; diaphragm with spermicide; or male condom and
diaphragm) from two weeks prior to administration of the first dose of
investigational product until 30 days after the final dose of study
medication.

- Vasectomized partner who has been documented to be sterile prior to the
female subject's entry and is the sole sexual partner for that female.

- NOTE: if women of childbearing potential are enrolled, they must use
double-barrier contraception in addition to oral contraceptives during the
active study treatment period until 6 weeks after the final dose of study
medication.

- Histologically confirmed malignant solid tumor and is scheduled to receive at least 2
courses of chemotherapy with docetaxel as a single intravenous dose of 20 to 40 mg/m2
given over a duration of one hour and repeated weekly.

- Received eight or fewer previous doses of docetaxel. Subjects that have received more
than eight doses of docetaxel must receive permission from the GSK medical monitor in
order to be eligible for the study.

- ECOG performance status score of less than or equal to 2

NOTE: If the subject's performance status deteriorates between the screening Visit and the
time of first dose of study drug to a score > 2, the subject will be excluded from the
study

- Adequate hematologic and other physiological organ function as evidenced by Absolute
Neutrophil Count ≥1500/mm3. Platelets ≥ 100,000/mm3 Hemoglobin ≥ 9 g/dL Serum
creatinine < 1.5 mg/dL Total Bilirubin ≤ upper limit of the reference range Aspartate
Transaminase (AST) < 2 x upper limit of the reference range Alanine Transaminase
(ALT) < 2 x upper limit of the reference range Alkaline Phosphatase < 2.5 x upper
limit of the reference range. Calculated creatinine clearance > 50 mL/min (measured
by Cockcroft Gault Formula;)

- Written informed consent is obtained prior to any study-specific procedures or
assessments.

- Able to swallow and retain oral medications.

Exclusion Criteria:

- Pregnant or lactating.

- Received radiation therapy to the abdomen or the pelvis in the 28 days prior to
receiving the first dose of study medication or that are scheduled to receive
radiation therapy to the abdomen or the pelvis in the six days following the first
dose of study medication.

- Received a dose of docetaxel during the week prior to Day -1.

- Known central nervous system primary or metastatic malignancy, unless successfully
treated with excision or radiation and has been stable for at least 3 months prior to
receiving the first dose of study medication.

- Active systemic infection or any poorly controlled medical condition (other than
malignancy) which, in the opinion of the investigator, may confound the results of
the study or pose an unwarranted risk to the subject. Subjects with a previous, but
not current, history of alcoholism may be permitted provided that, in the
investigator's opinion, the subject's disease state will not confound the results of
the study.

- Receiving regular treatment with high dose systemic corticosteroid therapy or steroid
dose within 72 hours prior to receiving the first dose of study medication. Topical
steroids and inhaled corticosteroids with a steroid dose of less than or equal to 10
mg prednisone daily (or its equivalent) are permitted if the subject has been on this
dose for at least 14 days prior to dosing.

- Hypersensitivity or contraindication to ondansetron or other 5-HT3 receptor
antagonist, dexamethasone, docetaxel, casopitant, or any component of the above
mentioned medications.

- Received an investigational drug within the 28 days or five half-lives (whichever is
longer) prior to receiving the first dose of study medication, or is scheduled to
receive any investigational drug during the study.

- Use of strong inhibitors of CYP3A4 or CYP3A5 prior to the first dose of study
medication

- Use of inducers of CYP3A4 or CYP3A5 (other than steroids described in Exclusion
Criteria 5) within 14 days prior to the first dose of study medication

- Use of drugs with a narrow therapeutic index that interact with the P-glycoprotein
pathway within 14 days prior to the first dose of study medication until 14 days
after the last dose of docetaxel including digoxin.

- Use of drugs with a narrow therapeutic index that are metabolized by CYP2C8 within 14
days prior to the first dose of study medication including repaglinide and torsemide.

- Disease that will significantly affect absorption of oral medications.

- Inadequate venous access for pharmacokinetic sampling.

- Unresolved Grade 2 or worse toxicity from prior therapy.

- Active peptic ulcer disease (PUD) or a history of PUD of unknown etiology. NOTE:
Subject is eligible to enter and participate in this study if they have a history of
PUD of known etiology with documentation from a gastroenterologist or other qualified
physician of the etiology of the PUD and that effective treatment was provided with
full eradication of ulcers and symptoms. Subjects who present with symptoms of
gastroesophageal reflux disease (GERD) are eligible. However, if the investigator
suspects PUD in such a subject, the subject must have a GI assessment to rule out
PUD. If assessment is negative, subject may enter the study. For these subjects,
appropriate steps must also have been taken to minimize the risk of reoccurrence. If
PUD was non-steroidal anti-inflammatory drug (NSAID) induced, the subject should no
longer be taking NSAID medication(s). If PUD was induced by H. pylori, the subject
should have been appropriately treated.

- Stool positive for occult blood. Test may be repeated once if subject did not abstain
from red meat for the previous three days.

- Pepsinogen level below the lower limit of laboratory reference range (LLRR).

- Troponin level above 10% of the coefficient of variation of the assay as determined
by the laboratory performing the test.

- Calculated QT interval (QTc) > 480 msecs.

- Clinically significant cardiac disease that would interfere with participation in the
study as determined by the investigator.

- Known or suspected iron deficiency.

- Use of NSAIDS, including aspirin at any dose, and including COX2 inhibitors. These
medications are prohibited 7 days prior to administration of study drug and for the
duration of the study until 72 hours after the last dose of study drug.
