Filter by:Radiotherapy involves the use of high-energy X-rays, which can be used to stop the growth of tumor cells. Radiotherapy constitutes an essential avenue in the treatment of brain tumors. The modern techniques of radiotherapy involve radiation planning techniques guided by computer algorithms aimed to deliver high doses of radiation to the areas of brain with tumors and limit the doses to surrounding normal structures. Artificial intelligence uses advanced analytical processes aided by computational analysis, which can be undertaken on the medical images, and radiation planning process. We plan to use artificial intelligence techniques to automatically delineate areas of the brain with tumor and other normal structures as identified from images. Also, we will use artificial intelligence on the radiation dose images and other images done for radiation treatment to classify tumors with good or bad prognoses, identify patients developing radiation complications, and detect responses after treatment.
SJELIOT is a phase 1 trial that aims to explore the combination of prexasertib with established DNA-damaging agents used in medulloblastoma to evaluate tolerance and pharmacokinetics in recurrent or refractory disease. Additionally, a small expansion cohort will be incorporated into the trial at the combination MTD/RP2D (maximum tolerated dose/recommended phase two dose) to detect a preliminary efficacy signal. Stratum A: Prexasertib and Cyclophosphamide Primary Objectives - To determine the safety and tolerability and estimate the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) of combination treatment with prexasertib and cyclophosphamide in participants with recurrent/refractory Group 3 and Group 4 medulloblastoma and recurrent/refractory sonic hedgehog (SHH) medulloblastoma. - To characterize the pharmacokinetics of prexasertib in combination with cyclophosphamide. Secondary Objectives - To estimate the rate and duration of objective response and progression free survival (PFS) associated with prexasertib and cyclophosphamide treatment in this patient population. - To characterize the pharmacokinetics of cyclophosphamide and metabolites. Stratum B: Prexasertib and Gemcitabine Primary Objectives - To determine the safety and tolerability and estimate the MTD/RP2D of combination treatment with prexasertib and gemcitabine in participants with recurrent/refractory Group 3 and Group 4 medulloblastoma. - To characterize the pharmacokinetics of prexasertib in combination with gemcitabine. Secondary Objectives - To estimate the rate and duration of objective response and PFS associated with prexasertib and gemcitabine treatment in this patient population. - To characterize the pharmacokinetics of gemcitabine and gemcitabine triphosphate (only at St. Jude Children's Research Hospital).
This is a prospective, observational registry in patients who have been prescribed Gliadel Wafer by the physician as part of usual care.
