A Safety Study to Evaluate Pazopanib Eye Drops in Healthy Volunteers

This study has been completed.
Information provided by:
GlaxoSmithKline Identifier:
First received: February 18, 2010
Last updated: March 17, 2011
Last verified: March 2011
A study to determine the safety and tolerability of pazopanib eye drops. The study will also determine how the drug is absorbed and metabolized over time. Repeat doses of eye drops will be administered to healthy adult volunteers over a 14-day period with one additional dose given on the 15th day of the session. Three groups of subjects may receive either active drug or placebo (drops without drug). The first group of subjects will receive a maximum of 1.6mg of pazopanib or placebo. The dose of drug to be given to the next two groups will be determined based on the results of the first group of subjects. The last group of subjects will be of Japanese descent.

Primary Outcome Measures:
  • Clinical safety data from AE reporting, clinical observations, physical examinations, vital signs (blood pressure and heart rate), clinical laboratory tests including urinalysis, general ophthalmic examinations, and best-corrected visual acuity tests [ Time Frame: 2 weeks ]
  • Primary pharmacokinetic endpoints will include: AUC(0-24), Cmax after repeat administration of pazopanib ophthalmic solution, Tmax, and trough steady-state plasma pazopanib concentration (Cτ) [ Time Frame: 2 weeks ]

Secondary Outcome Measures:
  • Secondary pharmacokinetic parameters include: area under the plasma drug concentration versus time curve [AUC(0-t)], observed accumulation ratio (Ro), and apparent terminal half-life (t1/2) after repeat administration will be analyzed [ Time Frame: 2 weeks ]

Detailed Description:
The purpose of this study is to characterize the ocular safety and tolerability, the systemic safety and tolerability, and the pharmacokinetic profile of repeat doses of a higher strength ophthalmic formulation of pazopanib, 10 mg/mL. The higher strength formulation provides an opportunity to increase the total daily dose of pazopanib administered. In this 3-cohort study, healthy adult volunteers will participate in one 14-day repeat-dose session (plus a single dose on day 15), randomized to receive either pazopanib eye drops or placebo. Subjects in cohort 1 will receive 1 drop four times daily for a calculated total daily dose of 1.6 mg. The dosage regimen for two subsequent cohorts will be determined based on the emerging safety profile. The Japanese population chosen for the third cohort will provide a safety and tolerability profile as well as the pharmacokinetic profile of pazopanib prior to further development of this formulation in Japanese patients with AMD.

Ages Eligible for Study:   20 Years to 64 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • AST, ALT, alkaline phosphatase and bilirubin ≤ 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
  • Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
  • Male or female ≥ 20 to 64 years of age, at the time of signing the informed consent.
  • A female subject is eligible to participate if she is of non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea. In questionable cases, a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<140 pmol/L) is confirmatory
  • Body weight ≥ 50 kg for men and ≥ 45 kg for women and body mass index (BMI) within the range 18.5 - 32 kg/m2 (inclusive), where BMI = (weight in kg)/(height in meters)2.
  • Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • Average QTcF < 450 msec or QTc < 480 msec in subjects with bundle branch block.
  • Best-corrected visual acuity better than 20/80 (Snellen equivalent) in both eyes.

Exclusion Criteria:

  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
  • History of clinically relevant coronary heart disease, uncontrolled hypertension, renal disease, diabetes mellitus, impaired endocrine, thyroid, or respiratory function, or psychotic mental illness
  • History of any hemorrhagic event (hemoptysis, cerebral or gastrointestinal) within 6 months of screening
  • Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months of screening.

  • A positive pre-study drug/alcohol screen
  • A positive test for HIV antibody
  • Blood pressure (SBP/DBP) > 140/90 mmHg at screening

  • Prior history of ocular allergy, unless symptom-free for at least 6 months from first dose.
  • An unwillingness to refrain from wearing contact lenses during the study and up to 2 weeks before the study start
  • History of sensitivity to any of the study medications or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation

an average weekly intake of >14 drinks for males or >7 drinks for females. One drink is equivalent to 12 g of alcohol: 12 ounces (360 mL) of beer, 5 ounces (150 mL) of wine or 1.5 ounces (45 mL) of 80-proof distilled spirits

  • Participation in a clinical trial where the subject has received an investigational product within 30 days, 5 half-lives, or twice the duration of the biological effect of the investigational product (whichever is longer) prior to the first dose of study medication

  • Consumption of red wine, seville oranges, grapefruit or grapefruit juice within 7 days prior to the first dose of study medication
  • Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period

  • For Cohort 3, the following additional inclusion criterion applies:
