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

Phase 1
Completed
Conditions
Carcinoma, Renal Cell
Interventions
Registration Number
NCT00158782
Lead Sponsor
GlaxoSmithKline
Brief Summary

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.
