Tipifarnib is a potent and selective, orally available nonpeptidomime, Tic FTI erf Leads both phase I and phase II metabolism in the liver A Phase I study of the Consortium tipifarnib p Pediatric brain tumors was performed to describe the dose-limiting side effects and beautiful TW-37 protect the maximum tolerable Possible Dose by simultaneous oral administration of tipifarnib radiotherapy and p nondisseminated pediatric patients, diffuse intrinsic BSG. This study provided the basis for a Phase II study of tipifarnib PBTC simultaneously and managed by radiation therapy in children with BSG. Materials and Methods The primary objectives of the study Re aim of the study was to determine the maximum tolerable Possible dose of tipifarnib administered protect fa beautiful It concomitant radiotherapy at p Nondisseminated pediatric patients, diffuse intrinsic BSG.
A secondary Res goal was the toxicity of th With tipifarnib treatment in combination with radiotherapy and more connected to describe. Another secondary Res target, which will GSK256066 be presented separately, it was the radiological changes Ver Tipifarnib in BSG with radiotherapy and MRI, spectroscopy, perfusion and diffusion imaging and PET characterize treated. Eligibility for Sick Children and over the years or less and recently new U diagnosed diffuse intrinsic BSG nondisseminated for this study. Other suitable criteria for assessment of Karnofsky performance score or Lansky performance, bone marrow function, and appropriate for a ad Quate renal and hepatic function. Patients again U before irradiation, chemotherapy or experimental anti-cancer agents, except for the stero Of, and in patients with a known allergy to topical or systemic imidazoles were excluded.
Patients receiving enzyme-inducing anticonvulsants were also excluded, as these have proven to significantly increased Hen tipifarnib the game. The ethics committee of each institution approved the protocol PBTC before initial patient enrollment and continuing approval was w During the study retained. Patients, parents or guardians gave written Einverst ndnis Consent was obtained and, if applicable,. In accordance with the Locational IRB policy before registering Studies before and w During treatment, a detailed history was obtained, k Rperliche and neurological examinations were performed before treatment, in w Chentlichen distances Ends w During the first weeks of treatment and monthly thereafter.
