Filter by:Study Hypothesis: Patients with local renal cell carcinoma who are treated neoadjuvantly with Sutent may show a radiologic response to the study drug (Sutent). The study is looking at the neoadjuvant (pre-surgery) administration of Sutent in patients with localized kidney cancer. The purpose of this research is also to evaluate both the safety and effectiveness of Sutent in this patient population.
Besides liver transplantation, the curative treatment of primary hepatic cancer with cirrhosis remains the surgical resection. Radiofrequency or cryotherapy currently allow local ablation of small cancer, with very good results. However, all these treatments are followed by high rates of recurrence (50 - 70% at 5 years). Then, it seems essential to associate to the surgical resection or to the local ablation as "adjuvant" treatment, in order to prevent or to decrease the rate of recurrence. However, no evidence supports this attitude. Therefore, following curative treatment of primary hepatic cancer with cirrhosis, we propose to compare treated to untreated patients. Postoperative treatment means either intra-arterial chemotherapy or systemic chemotherapy. The main criterion of the study is time of survival without recurrence. The main secondary objective is the safety.
Hepatocellular carcinoma (HCC) is the fifth commonest cancer in the world with poor prognosis, as the annual mortality is almost equivalent to the incidence. This is mainly due to late diagnosis and co-morbid liver dysfunction. HCC is prevalent in our region than in the West due to prevalent Hepatitis B infection and carriers. At the time of diagnosis, only 10 - 20% of HCC patients are candidates for liver resection or transplantation. Almost 40-50% of patients have such poor liver function and co-morbid conditions that only supportive cares are offered. Thus the median survival time is 18-24 months for resectable disease, 6 months for unresectabe disease and 3 months for metastatic disease. Current screening methods for HCC in high risk patients depend on alpha-fetoprotein (AFP) and ultrasound of the liver. Neither test is sensitive or specific enough for early detection. Therefore, early diagnosis with novel protein biomarkers is needed urgently and may provides hope to improve treatment outcome. Our preliminary study in 49 HCC patients have identified several proteins such as truncated complement C3a, albumin, B2 microglobulin, may be potentially helpful in early diagnosis. We have started a large prospective and longitudinal study in July 2006, with nearly 100 patients accrued. This application is to extend and expand our current study. We aim to (i) identify and validate novel protein biomarkers for early diagnosis of HCC (ii) conduct longitudinal proteomics with most up-to-date methods to discover new biomarker for early detection and prognostication of HCC (iii) set up gene and plasma depository and clinical database for HCC in collaboration with Singapore Tissue Network.
This phase II trial is studying how well dasatinib works in treating patients with advanced liver cancer that cannot be removed by surgery. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Research Objective and Study End Points To evaluate the anti-HBV as well as HCC recurrence reducing effects of standard (18 months) lamivudine treatment at time of HBV reactivation with hepatitis flare up (HBV DNA > 105 copies/mL and ALT level > 2.0 x UNL) or prophylactic, prolong (36 months) adefovir dipivoxil therapy in post-operative HBsAg(+),< 5 cm HCC patients, and to compare the results of who group with historical controls (T1297, HBsAg+,< 5 cm HCC cohort),in terms of the following endpoints. 1. Primary endpoint: the 3-years recurrence rate (excluding those recur within first year). 2. Secondary endpoints: the first 2 year tumor recurrence rates the recurrence-free survival the overall survival. anti-viral efficacy, i.e. biochemical response and viral response rate. to correlate the changes of viral titer with the clinical outcome in post- operative HCC patients with adjuvant lamivudine or adefovir therapy.
This pilot clinical trial studies how well pazopanib hydrochloride works in treating patients with breast cancer that is newly diagnosed or has come back at or near the same place as the original tumor and can be removed by surgery. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by preventing the growth of new blood vessels necessary for tumor growth. Giving pazopanib hydrochloride before surgery may make the tumor smaller and reduce the amount of tissue that needs to be removed.
To evaluate the safety and toxicity of azacitidine (5-azacitidine, Vidaza®) and cisplatin combination in patients with squamous cell carcinoma of head and neck (SCCHN).
The primary objectives of this study are: 1. To evaluate the efficacy of glufosfamide in subjects with extensive recurrent sensitive small cell lung cancer (SCLC) as measured by objective response rate 2. To evaluate the safety of glufosfamide in subjects with extensive recurrent sensitive SCLC The secondary objectives are: 1. To evaluate the efficacy of glufosfamide in subjects with extensive recurrent sensitive SCLC as measured by duration of response, progression-free survival and overall survival 2. To evaluate the pharmacokinetics of glufosfamide and isophosphoramide mustard (IPM) The exploratory objectives of this trial are: 1. To evaluate the effect of glufosfamide on lung cancer symptoms 2. To evaluate the role of tumor cell glucose transporter expression on the efficacy of glufosfamide
This study randomized patients with advanced pancreatic islet cell tumors to receive either sunitinib or placebo. Patients who were randomized to sunitinib received 37.5 mg of sunitinib daily, those randomized to placebo received a tablet that looked similar but had no active drug. Neither the patient or the doctor knew whether the patient was receiving sunitinib or placebo. Patients were followed to determine the status and size of their tumors, survival, quality of life and safety of the drug. The study was designed to detect a 50% improvement in median PFS[Progression Free Survival] with 90% power and was to enroll 340 subjects. An interim analysis was planned when 130 events had occurred, and the final analysis was to be conducted when 260 events had occurred. Study A6181111 was stopped early during the enrollment period because of a clear and clinically meaningful improvement in efficacy for the sunitinib treatment arm as recommended by the DMC [Data Monitoring Committee]. The actual number of subjects enrolled was 171 and the actual number of PFS events recorded was 81 PFS events. The decision to terminate the study was not based on safety concerns related to sunitinib administration.
Rationale for Study Oral mucositis is a major complication arising from contemporary chemoradiation treatment of patients with head and neck cancer. No effective therapy exists to prevent this complication in this population. MRX-1024 is an investigational agent that has demonstrated in in vitro and in vivo experiments to have the potential to exert a protective effect in normal mucosa cells, without interfering with the intended antitumor effect of radiation. A pilot Phase 1 study of MRX-1024 was conducted in India in patients with head and neck cancer receiving radiation alone or radiation in combination with cisplatin or carboplatin. MRX 1024 doses of 100 mgkg given orally twice a day, five days a week during radiation treatment cycles, were well tolerated and appeared to exert a protective effect against the development of severe mucositis. Twice daily doses of MRX 1024 impose a certain level of inconvenience to the patient, to their clinic companion, and to the general work flow within radiation oncology clinics. This study is designed to study the safety and pharmacokinetics of both single daily dose and twice daily dose regimens of oral MRX 1024 given in conjunction with daily radiation fractions and intermittent high-dose cisplatin to patients with high-risk for recurrence head and neck cancer following surgical resection. The study will also document the incidence and severity of oral mucositis that occurs following such therapy. The results will be instrumental in determining the regimen of MRX 1024 to use in subsequent definitive clinical trials.
