Filter by:This phase II trial studies how well temsirolimus and cixutumumab works in treating patients with locally advanced, metastatic, or recurrent soft tissue sarcoma or bone sarcoma. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cixutumumab, can block tumor growth by blocking the ability of tumor cells to grow and spread. Giving temsirolimus with cixutumumab may be an effective treatment for soft tissue or bone sarcoma.
The primary objectives of this trial are the determination of feasibility and toxicity of Heavy Ion Radiotherapy (C12) in patients with non-resectable osteosarcoma. Secondary endpoints are tumor response, disease free survival and overall survival. The aim is to improve outcome for patients with non-resectable osteosarcoma.
Approximately 150 new cases of osteosarcoma are reported each year in France, of which 15 to 20% are metastatic. Further to the initial standard care, about 45% of the patients relapse within a median duration of 20 months. Result of the OS94 study results and of the investigation performed within the CRLCC, indicate that 25 to 30 patients (children and adults) experience an osteosarcoma relapse each year in FRANCE. According to several studies, the 5-year overall survival rate of patients in first relapse is 23-28%,with a median post relapse survival of 10 to 17 months. Multiple relapse cases are also reported in the COSS study, with a median time to second relapse of 0.8 year. At present, there is no reference treatment for the standard care of osteosarcoma relapse in FRANCE. Thiotepa is known for its antitumor effect in numerous malignant tumors. In 2007, a study from our institution reported that about 35% of all osteosarcoma relapses are treated with a high-dose thiotepa while the efficacy and tolerance of this therapeutic strategy have never been assessed. These results highlight the need to the evaluate the efficacy and tolerance of this high-dose of thiotepa within a clinical trial and its inclusion in the standard care of the osteosarcoma at relapse.
This research trial studies blood samples from patients with osteosarcoma. Studying the genes found in samples of blood from patients with osteosarcoma may help doctors identify biomarkers related to the disease.
Patients with relapsed solid tumors such as sarcomas and neuroblastoma have a poor survival, generally < 20%. There is an urgent need for new treatments that are safe and effective. HSV1716, an oncolytic virus, is a mutant herpes simplex virus (HSV) type I, deleted in the RL1 gene which encodes the protein ICP34.5, a specific determinant of virulence. Mutants lacking the RL1 gene are capable of replication in actively dividing cells but not in terminally differentiated cells - a phenotype exploited to selectively kill tumor cells. In previous clinical studies, HSV1716 has been shown to be safe when injected at doses up to 10^5 plaque forming units (pfu) directly into human high-grade glioma and into normal brain adjacent to tumour, following excision of high-grade glioma. In an extension study, HSV1716 has been shown to be safe when injected at a dose of up to 10^6 pfu directly into brain tumours. Replication of HSV1716 in human glioblastoma in situ has been demonstrated. Following a single administration of HSV1716 by direct injection into active recurrent tumor or brain adjacent to tumor, some patients have lived longer than might have been expected. This study seeks to evaluate the safety of a single injection of HSV1716 in the treatment of extracranial solid tumors in adolescents and young adults. HSV1716 has also proved safe when given by direct intra-tumoural injection in patients with squamous carcinoma of the head and neck, and in patients with malignant melanoma. Replication of HSV mutants in human sarcomas and neuroblastoma in cultured cells and human xenograft models has been demonstrated. This study is designed in two parts. PART 1 of the study specifies a single dose of virus. Participants who experience at least stable disease or relapse following a determination of stable disease, may qualify for subsequent doses in PART 2. PART 2 requires signing of a separate consent.

Background: - Informed consent is the process by which prospective participants in clinical trials learn about clinical research in order to decide whether they want to enroll in the study. It consists of meetings and discussions with the health care team. - Phase I clinical trials are designed to determine what dose of an investigational agent is safe to administer to patients. Objectives: - To study communication, comprehension and decision-making during the informed consent process. - To examine ethical, psychological, social, and educational issues regarding informed consent. - To help researchers understand how to improve informed consent and education about clinical research. Eligibility: - Parents or guardians of children with cancer who are being considered for participation in phase I clinical trials - Prospective patients for pediatric phase I clinical trials who are between 14 and 21 years of age. - Members of the research team who obtain consent from patients and families for pediatric phase I clinical trials Design: - Research assistants observe and record the informed consent conference held with the research team and the parents and children. - After the conference, the research assistant interviews the parents in a private area about their experience during the conference and their decision-making process. They are asked about their thoughts and opinions during the informed consent conference, including the decision-making process, communication and trust in the medical team. - With their parent's permission, patients are interviewed privately to discuss their experience during the informed consent conference. - After parents and patients have made their decision about participation in the study, they are interviewed again about how they made the decision, aspects of the communication during the conference, and how they feel about the doctor. This interview is also recorded. - Parents may be contacted 6 months to 2 years from the time of their participation to be part of a parent advisory group about the informed consent process.
The purpose of this study is to collect and store samples of blood and tumor tissue from patients with osteosarcoma. Collecting and storing samples of tumor tissue and blood from patients to test in the laboratory may help the study of cancer in the future.
Aim of this exploratory phase II study is to assess the clinical activity of sorafenib as single agent, in terms of percentage of patients with high grade advanced osteosarcoma free from progression following 4 months of therapy
This phase II trial is studying the side effects and how well cixutumumab works in treating patients with relapsed or refractory solid tumors. Monoclonal antibodies, such as cixutumumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.
The purpose of this study is to determine the overall best tumor response rate to dacarbazine given until disease progression as assessed by RECIST criteria, CT and clinical exams in patients with metastatic sarcomas.
