Filter by:PET CT is one of the imaging tools that are used for staging of urological malignancies. C11 Choline is a novel isotope with the advantage of its minimal secretion in the urine. This advantage makes it a potentially better metabolic marker then others such as FDG. Preliminary studies showed ~95% sensitivity in the diagnosis of TCC. Our Goal is to continue the evaluation of this method as a diagnostic and follow up tool in different urological malignancies.
Background: This prospective study was designed to be the first to evaluate the toxicity of radiofrequency ablation (RFA) in patients with recurrent pediatric solid tumors. Methods: From 2003 through 2006, we conducted a phase I, IRB-approved study of RFA for recurrent solid tumors. A multidisciplinary cancer management team selected appropriate candidates for the study. Imaging-guided RFA was performed percutaneously. Response was assessed at 3 months. Repeat RFA was performed for some incompletely ablated or new lesions.
Formation of new blood vessels (angiogenesis) is important for tumor growth in advanced cancer. It is known that tumors make a protein called vascular endothelial growth factor (VEGF). VEGF stimulates the formation of blood vessels that supply the tumor with nutrients and oxygen. PTC299 is an oral investigational new drug that has been shown to decrease production of VEGF in animal models of human cancer. In these animal models, oral PTC299 administration decreases VEGF levels in the tumor and in the bloodstream, decreases blood vessel numbers in the tumor, and significantly slows or halts tumor growth. When given in combination with the chemotherapeutic drug, docetaxel, PTC299 increases the antitumor activity over use of docetaxel alone. Safety studies in research animals indicate good tolerability at doses and drug levels that are higher than those planned for the clinical studies. Results from Phase 1a studies in healthy volunteers indicate that PTC299 achieves levels of PTC299 in the bloodstream that are known to be active in animal models of human cancer. This Phase 1b study is designed to test the hypothesis that PTC299 will be tolerable and will show evidence of anti-VEGF and antitumor activity when administered orally to participants with cancer.
Rationale: The Mammalian Target of Rapamycin (mTOR) is a large polypeptide serine/threonine kinase of 289 kDa; kinases have been shown to be important regulators of cancer cell cycle, proliferation, invasion, and angiogenesis, and mTOR has been shown to have a key role in the signaling of malignant cell growth, proliferation, differentiation, migration, and survival. Inhibition of mTOR would result in arrest of cell growth in the G1 phase of the cell cycle. Temsirolimus (CCI-779) is a soluble ester analogue of rapamycin (sirolimus) which has shown impressive in vitro and in vivo cytostatic activity in selectively inhibiting mTOR. In animal models, temsirolimus has demonstrated an impressive cytostatic effect on a wide variety of cancer cells. In vitro, it inhibited the growth of human T-cell leukemia, glioblastoma, melanoma, prostate, breast, renal cell, and pancreatic cells, all of which showed particular sensitivity to temsirolimus, with significant growth inhibition at concentrations of less that 0.01micrometers. In Phase I trials, temsirolimus has been investigated as a single agent on a weekly schedule as well as daily for 5 days every other week, and evidence of activity was observed over the entire dose range (15 - 220 mg/m2) in patients with both breast and renal cancer. There was no apparent relationship between exposure and clinical benefit, suggesting that the inhibition of mTOR may be achieved at doses well below dose levels that result in dose limiting toxicities. Major tumor responses were noted in Phase I trials in patients previously treated with lung, breast, renal as well as neuroendocrine tumors. Minor responses were noted in soft tissue sarcoma, endometrial, and cervical carcinoma. Docetaxel is a taxane analog which is active against many solid tumors including breast, non-small cell lung, prostate, gastric, ovarian, head and neck, and pancreatic cancers, soft tissue sarcoma, and melanoma. It has been shown in several Phase III studies to have clinically significant activity in several solid tumors. We propose treating patients with resistant solid malignancies with docetaxel and temsirolimus. In a study using human breast cancer cell lines, mTOR inhibition with rapamycin had a synergistic cytotoxic effect with paclitaxel. Given the novel mechanism of action of mTOR inhibitors and known synergistic activity of an mTOR inhibitor, rapamycin, with a taxane, paclitaxel, in vitro, we envision that this regimen would be highly active in patients with solid tumor malignancies. Objectives: Primary - To define the maximum tolerated dose (MTD) and dose-limiting toxicities (DLT) of temsirolimus in combination with pegylated liposomal doxorubicin in patients with resistant solid malignancies. - To determine the incidence and severity of other toxicities of temsirolimus in combination with pegylated liposomal doxorubicin in patients with resistant solid malignancies. Secondary - To assess the pharmacokinetic profile of temsirolimus in combination with pegylated liposomal doxorubicin. - To determine any anti-tumor activity and response to the combination of temsirolimus and pegylated liposomal doxorubicin in treatment of patients with resistant solid malignancies.

Pegylated liposomal doxorubicin has been FDA approved for use in refractory metastatic ovarian cancer and AIDS-related Kaposi's Sarcoma. It has also been shown to be effective in previously treated metastatic breast cancer. Combination studies in preclinical models suggest that rapamycin and its analogues are at least additive in effect with standard chemotherapy and radiation. In addition, studies in breast cancer cell lines suggest that the mTOR inhibitors may reverse resistance to anti-estrogen agents. Thus, we are proposing that the combination of temsirolimus and liposomal doxorubicin will be highly effective in metastatic solid tumor malignancies.

TB-403 is a monoclonal antibody directed against Placental Growth Factor (PlGF). The antibody binds to PlGF and inhibits the binding to it's receptor, VEGF-1. By preventing this binding, growth of tumor vessels are inhibited and tumor growth prevented. In this study we are investigating the tolerability and safety of TB-403 in patients with solid tumors who receives multiple intravenous doses of TB-403.
The main objective of this trial is to provide safety data in terms of drug-related adverse events (AE) for the recommendation of the dose for further trials in the development of BI 811283. Secondary objectives are the collection of antitumour efficacy data and the determination of the pharmacokinetic profile of BI 811283.
The purpose of this study is to evaluate the response rate (Complete Response (CR) and Partial Response (PR)) to carboplatin and DOXIL treatment in combination with bevacizumab in patients with platinum-sensitive recurrent ovarian, fallopian tube and primary peritoneal cancers. All patients will received DOXIL, carboplatin and bevacizumab for a maximum of ten 28-day cycles. Patients will be followed for six months following treatment to assess progression-free survival.
