Information provided by:
This Phase I, dose finding study evaluates the safety and tolerability of lapatinib, a dual tyrosine kinase inhibitor, and GW786034, an anti-angiogenesis agent, when given together. The study first will find the best doses using safety and blood concentration data of both agents. This is done enrolling stepwise, cohorts of 3 patients each and the last patient enrolled must reach at least Day 22 of continuous daily dosing before the next cohort at an increased dose can begin. If a patient in a cohort has a dose limiting toxicity before Day 22, then 3 more patients are studied at that same dose. If 2 of 6 patients have dose limiting toxicities within the first 22 days, the next cohort receives the next lowest dose. Otherwise each cohort has an increasing dose of one of the two agents. The second stage of the study will administer the best doses of the agents to about 16 patients to further study safety and collect more blood concentration data (more blood samples in the second phase compared to the first phase). The second stage has the advantage of using the best dose (decreases chance of receiving a sub-therapeutic dose) while it collects more blood samples and requires slightly more long clinic visits.

Primary Outcome Measures:
  • Changes in pre and post treatment lab values and monitoring/reporting AES.AE's throughout study [ Time Frame: throughout study ]
  • Labs every wk first cycle:day 1 subsequent cycles [ Time Frame: first cycle:day 1 subsequent cycles ]

Secondary Outcome Measures:
  • find max conc of drugs in blood and time it occurs find out if drugs are taken up by the body, how much/for how long find out if drugs affect the size of the tumor. Blood taken day 15, 22 or 37 and tumor assessed every 8 wks [ Time Frame: Blood taken day 15, 22 or 37 and tumor assessed every 8 wks ]

Estimated Enrollment: 65

    a) Non-childbearing potential (i.e., physiologically incapable of becoming pregnant), including any female who:

  • had a hysterectomy.
  • had a bilateral oophorectomy (ovariectomy).
  • had a bilateral tubal ligation.
  • is post-menopausal (a demonstration of total cessation of menses for 1 year).
  • childbearing potential, has a negative serum pregnancy test at screening, and agrees to one of the following:
  • an IUD with a documented failure rate of less than 1% per year.
  • vasectomized partner who is sterile prior to the female patient's entry and is the sole sexual partner for that female.
  • complete abstinence from sexual intercourse for 14 days before exposure to investigational product, throughout the clinical trial, and for at least 14 days after the last dose of investigational product.
