Study Of Safety And Tolerability Of GW786034 Given With Lapatinib In Cancer Patients

Completed · Phase 1

Conditions studied: Carcinoma, Renal Cell

In brief

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.

Who can join

Age: 21 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Histologically or cytologically confirmed diagnosis of advanced solid tumor refractory to standard therapy or for whom there is no standard therapy.
• Females are eligible if they are of:
• 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.
• double-barrier contraception (condom with spermicidal jelly, foam suppository, or film; diaphragm with spermicide; or male condom and diaphragm with spermicide).
• ECOG (Eastern Cooperative Oncology Group) PS 0 or 1.
• Adequate bone marrow function.
• Platelets greater than or equal to 75,000/mm3.
• ANC greater than or equal to 1,500/mm3 (1.5 x 109/L).
• Hgb greater than or equal to 9 g/dL (5 mmol/L).
• CLcr > 50 mL/min as calculated by the Cockcroft-Gault formula.

• PT/INR/PTT less than or equal to 1.2 x upper limit of normal.
• AST/ALT less than or equal to 3 x upper limit of normal.
• Has LVEF within normal range or above 50% based on MUGA/ECHO.
• Urinalysis for protein is < 2 (negative, trace, or 1). NOTE: If urinalysis is 2 or greater then a 24 hour urine for protein must demonstrate less than 1 gram of protein in 24 hours for patient to be eligible for enrollment.
• Able to swallow and retain oral medication.
• Has a life expectancy of at least 12 weeks.

• Has allergy to drug similar to lapatinib (e.g. allergic to Iressa(gefitinib) or Tarceva(erlotinib).
• Is using therapeutic doses of anti-coagulant.
• Has had major surgery, hormonal therapy, chemotherapy, radiotherapy, or other investigational agent within last 28 days.
• Pregnant or lactating.
• History or current GI (gastrointestinal) condition that alters stomach or gut emptying from normal (e.g. major surgery on the stomach).
• Bowel obstruction or chronic diarrhea.
• Psychological or geographical conditions that would prevent him/her from being a good candidate.
• Do not have accessible veins for venipuncture.
