Filter by:This is a phase 1, multi-centre, sequential cohort, open-label, dose-escalation study of the safety, tolerability, and PK of ANG1005 in patients with solid tumors (with or without brain metastases). ANG1005 will be given by IV infusion once every 21 days (1 treatment cycle). Each patient will participate in only 1 dose group and will receive up to 6 cycles of treatment provided there is no evidence of tumor progression, there is recovery to ≤Grade 1 or baseline nonhematologic, ANG1005-related toxicity (except alopecia), the absolute neutrophil count is ≥1.5 x 109/L, and the platelet count is ≥100 x 109/L.
Lung cancer is a leading cause of death worldwide. Brain metastases manifest as the first site of disease failure in between 15-30% of patients with non-small cell lung cancer (NSCLC). The standard treatment for patients with multiple brain metastases is whole brain radiotherapy but this results in only a modest survival of 3-6 months. Drugs that can enhance the effect of cranial irradiation (radiosensitizers) may improve the the response rates. Erlotinib (Tarceva) is an oral agent that has been registered for treatment in patients with metastatic NSCLC. Erlotinib has shown tumor activity in patients presenting with brain metastases, and preclinical studies show that it may be a radiosensitizer. As a prelude to studies investigating the combination of Erlotinib and cranial radiotherapy, the present study will be performed to evaluate the safety of combining both these treatments.
The purpose of this study is to: Find out how safe and effective (by monitoring the good and/or bad effects) treatment with high dose temozolomide, thiotepa and carboplatin with stem cell rescue followed by 13-cis-retinoic acid has on children and adolescents with recurrent/refractory brain tumors Find out how the body uses 13-cis-retinoic acid by studying the your blood levels and proteins in the blood that break down the 13-cis-retinoic acid Determine how well 13-cis-retinoic acid penetrates into the spinal fluid.
The goal of this clinical research study is to find the highest safe dose of lomustine (CCNU, CeeNUTM) that can be given with temozolomide (TemodarTM) and thalidomide (ThalomidTM) in the treatment of metastatic melanoma that has spread to the brain. The safety and effectiveness of this combination therapy will also be studied.
The purpose of this study is to determine the effect of the surgical intervention and insertion of GLIADEL wafers on the neurocognitive functioning in patients with metastatic brain cancer.
This study is conducted to compare the contrast effect and safety of SH L562BB with ProHance, which has already been approved as a pharmaceutical product of similar indication.
Primary Objective: - Determine the interindividual range and median of individual maximum tolerated doses of valproic acid administered as one time evening dose in conjunction with a dose oral etoposide (50 mg/m2/day for children, but only 25mg/m2/day for adults to start) for four different age groups. Secondary Objectives: - Determine the qualitative and quantitative toxicity and reversibility of toxicity of valproic acid in conjunction with oral etoposide, - To investigate the clinical pharmacokinetics of valproic acid when given in conjunction with oral etoposide, - To describe quality of life of patients with relapsed, or progressive central and peripheral nervous system tumors when treated with oral valproic acid and etoposide, - To observe and describe the response pattern of progressive central nervous system tumors treated with oral valproic acid and etoposide, - To observe and describe event free survival time and overall survival time of patients with relapsed, or progressive central nervous system tumors when treated with oral valproic acid and etoposide, - To determine if histone deacetylase activity and topoisomerase expression in lymphocytes of patients is related to valproic acid levels, and - To determine, if the individual maximal tolerated dose (iMTD) depends on the initial performance status of the patient in the beginning of the treatment.
The Environmental Protection Agency has recognized that organophosphorus pesticides require close regulation and continued monitoring for human health effects and some (e.g chlorpyrifos) have been phased-out from the consumer market due to the special risk that it posed for children. There is growing evidence in support of the association between pesticide exposure and childhood leukemia. Studies of pesticides and their association with childhood cancer have been limited by study designs, self-reporting and lack of biological measurements. While several large studies in California found little evidence of an association between agricultural pesticide use and childhood leukemia, these results are in contrast with the associations observed with household exposures to pesticides. The real association may depend on timing of exposure, type of pesticide, dose and pathway of exposure. Furthermore, some persons may be more susceptible to the effects of specific pesticides due to inherited mutations in their detoxification pathways. We are conducting a pilot study to test the hypothesis that environmental exposure to pesticides in pregnancy or during the neonatal period, together with genetic susceptibility may lead to childhood ALL or brain cancer. The study is a multicenter, case-control study, based on collaboration between clinical researchers and basic science research to evaluate the risk for childhood cancer in relation to measured levels of pesticides (and their metabolites) and genetic polymorphisms. Biomarkers will be used to examine the risks of chronic low-dose exposures, and to characterize relationships between specific pesticides, childhood cancer and genetic susceptibility. Hypothesis: Interaction between environmental factors (pesticides) and maternal or child genetic polymorphisms may lead to childhood cancer.
The goal of this clinical research study is to learn if the combination of 6-Thioguanine, Xeloda (capecitabine), and Celebrex (celecoxib) with Temodar (temozolomide) or Lomustine (CCNU) is effective in the treatment of recurrent or progressive anaplastic glioma or glioblastoma multiforme in patients who have failed previous treatments. The safety of these combination treatment will also be studied. Objectives: 1.1 To determine the efficacy, as measured by 12 month progression-free survival, of TEMOZOLOMIDE or CCNU with 6-THIOGUANINE followed by CAPECITABINE and CELECOXIB in the treatment of patients with recurrent and/or progressive anaplastic gliomas or glioblastoma multiforme. 1.2 To determine the long-term toxicity of TEMOZOLOMIDE or CCNU with 6-THIOGUANINE followed by CAPECITABINE and CELECOXIB in recurrent anaplastic glioma or glioblastoma multiforme patients treated in this manner. 1.3 To determine the clinical relevance of genetic subtyping tumors as a predictor of response to this chemotherapy and long term survival
This is a Phase I, open-label, multi-centre study designed to assess the safety and tolerability of Cediranib in combination with lomustine in patients with primary recurrent malignant brain tumour.
