Filter by:The prognosis of children and adolescents with high risk tumors of the central nervous system and other miscellaneous solid tumors is poor despite modern treatment protocols. Frequently, physicians suggest additional therapy with high dose chemotherapy after a good initial response to standard doses of treatment has been obtained, so as to reduce the chance that the tumor will recur. We propose a regimen of high dose thiotepa and melphalan followed by rescue of the patient's previously stored hematopoietic (blood manufacturing) system with blood stem cells. The aim of this study is to prove that this therapy is tolerable in children and adolescents, that it results in tolerable levels of toxicity, and that it improves the survival of this group of children as compared to standard therapy given in the past
The aim of this study is to evaluate the feasibility and safety of laparoscopic liver surgery.
Genasense® is currently administered to subjects in clinical studies as a multiple-day continuous intravenous infusion. Subjects are treated on an outpatient basis and carry a pump that delivers the drug through a peripheral or central intravenous line. The route of administration limits the convenience of treatment, and catheter-related complications have been reported. This study is designed to evaluate the pharmacokinetics and safety of G3139 administered by subcutaneuous injection.
To determine the feasibility and safety of administering YM155 in combination with docetaxel
This is a phase I, multi-center, open-label, dose-escalation study of TH-302 in patients with advanced solid tumors. TH-302 is a hypoxia activated product designed to exploit the hypoxic nature of tumors. The study is designed to establish the safety including the maximum tolerated dose, the pharmacokinetics, and the anti-tumor activity of TH-302.
The uptake of iodide by thyroid cells requires the expression of sodium iodide symporter (NIS). Thyroid benign and malignant tumors have low iodide uptake activity. Previous studies of NIS expression with RT-PCR and immunohistochemistry showed divergent data. NIS protein was overexpressed in thyroid cancer. The aim of this study was to investigate the NIS transcript levels and its presence and localization in 30 samples of thyroid tumors (14 benign and 16 malignant) and in their surrounding non-tumoral tissues (NT), by real time RT-PCR and immunohistochemistry, respectively. Our results revealed lower gene expression in 78.6% of the benign tumors and 100% of the carcinomas when compared with the NT samples, using GHPDH as a housekeeping gene. Immunohistochemical staining revealed presence of NIS protein in 100% of the non-tumoral samples, 100% of the benign tumors and 93.75% of the malignant tumors. NIS protein was identified at basolateral membrane in 23.3% of non-tumoral samples, 14.3% of benign and 12.5% of malignant tumors. Stronger cytoplasmatic immunostaining of NIS protein was detected in 64.3% of benign tumors and in 87.5% of malignant tumors when compared to NT. Association between low gene expression and strong cytoplasmatic immunostaining was found in 50% of benign tumors and 87.5% of malignant tumors. We concluded that the reduced NIS gene expression in thyroid tumors associated with strong intracytoplasmatic staining may be due to its incapacity to migrate to cellular membrane.
To estimate the effect of second-line panitumumab monotherapy on objective response in patients with metastatic or recurrent squamous cell carcinoma of head and neck (SCCHN).
The purpose of this trial is to determine the effect of food versus a fasted state on single-dose pharmacokinetics of BMS-540215, the active metabolite of Brivanib alaninate
The purpose of this trial is to determine the mass balance, pharmacokinetics, metabolism, and routes and extent of elimination of BMS-582664
The purpose of the study is to assess the safety and establish the maximum tolerated dose (MTD) of the combination of BSI-201 with chemotherapeutic regimens in adult subjects with histologically or cytologically documented advanced solid tumors. Based on data generated by BiPar/Sanofi, it is concluded that iniparib does not possess characteristics typical of the PARP inhibitor class. The exact mechanism has not yet been fully elucidated, however based on experiments on tumor cells performed in the laboratory, iniparib is a novel investigational anti-cancer agent that induces gamma-H2AX (a marker of DNA damage) in tumor cell lines, induces cell cycle arrest in the G2/M phase in tumor cell lines, and potentiates the cell cycle effects of DNA damaging modalities in tumor cell lines. Investigations into potential targets of iniparib and its metabolites are ongoing.
