Filter by:This phase II trial studies how well antiandrogen therapy, abiraterone acetate, and prednisone with or without neutron radiation therapy work in treating patients with prostate cancer. Hormone therapy such as antiandrogen therapy may fight prostate cancer by blocking the production and interfering with the action of hormones. Abiraterone acetate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Neutron radiation therapy uses high energy neutrons to kill tumor cells and shrink tumors. It is not yet known whether antiandrogen therapy, abiraterone acetate, and prednisone with or without neutron radiation therapy may work better in treating patients with prostate cancer.
The safety run-in portion of this study is designed to identify the optimal dose of VSV-IFNβ-NIS in combination with pembrolizumab in patients with solid tumors and follows the 3+3 design. The expansion portion will use one-sample binomial designs to assess the efficacy of the combination in patients with refractory NSCLC or NEC. The optimal dose (RP2D) determined in the dose escalation portion of the trial will be used for the expansion portion. The study has been conducted with a dose of 1.7 × 1010 as the recommended phase II dose in an expansion cohort of 10 patients with NSCLC. However, current data suggests that VSV-IFNβ-NIS doses of up to 1.7 × 1011 is safe and likely more efficacious. Thus, this study will test a second VSV-IFNβ-NIS dose level, 1.0x1011 TCID50. A safety assessment will be carried out after 3 patients are enrolled. If this dose schedule is well tolerated and virus PK are not negatively impacted, both the NSCLC and NEC expansion cohorts will open using this dose schedule. If 2 of the first 3 patients or 2 of the first 6 patients experience a DLT, the dose will be de-escalated to 5 x 1010. The safety run-in/dose escalation portion of this study is expected to require a minimum of 3 patients and a maximum of 18 patients (6 patients per dose level). The expansion portion of this study is expected to require a minimum of 10 per cohort. The NSCLC and NEC patients enrolled at the identified optimal dose in the dose escalation cohort would be included in the dose expansion cohort if they are evaluable for the primary endpoint in the expansion portion (4 dose escalation patients at the optimal dose are expected to roll over to the expansion). Therefore, the overall sample size will be a maximum of 40 patients.
To assess the diagnostic accuracy of 18F-Fluorocholine PET/CT for the detection of medullary thyroid cancer in patients with primary and recurrent disease.
Medullary thyroid carcinoma (MTC) develops at the expense of calcitonin cells and is often characterized by lymph node metastases and sometimes visceral metastases. Improvement of preoperative diagnosis is of major importance in CMT because the quality of the initial surgery determines the prognosis. In recent years, 18F-fluorodihydroxyphenylalanine (18F-FDOPA) PET / CT was considered the most sensitive functional imaging tool in the evaluation of persistent CMT. To date, 18F-FDOPA PET at initial diagnosis has been reported in a few clinical cases. The main objective is to demonstrate that 18F-FDOPA PET provides additional information compared to conventional imaging on the initial diagnosis of CMT patients. The secondary objectives are to describe the nature of the information provided by PET / CT imaging, the main factors influencing tracer uptake and the positivity of PET / CT, and the impact of the examination on the care of the patient. This is a prospective, multicenter and open study. Patients with TCM who have serum calcitonin> 150 pg / ml at initial diagnosis and have performed baseline imaging examinations within the last 3 months will be included in the study . A PET at 18F-FDOPA will be performed according to a very powerful acquisition protocol. Image analysis will be performed blindly from the results of conventional imaging. All exams will be compared, in accordance with the gold standard. Therapeutic intentions will be collected before and after the PET imaging, as well as the actual management in place.
The purpose of this study is to see if the use of 68Gallium- positron emission tomography and computer tomography (PET/CT) scans along with NETSPOT® (Advanced Accelerator Applications USA, Inc.) can better define the localization of Neuroendocrine tumors enhancing the surgical removal of Neuroendocrine tumors (NETs).
This is a prospective observational study which aims to evaluate; The prevalence of pancreatic insufficiency in patients with pancreatic malignancies (adenocarcinoma and neuroendocrine tumours). The most appropriate diagnostic strategy. The impact that an adequate diagnosis and treatment may have on patients' outcome.
CVM-1118 (TRX-818) is a new small molecule chemical entity being developed as a potential anti-cancer therapeutic by TaiRx, Inc. CVM-1118 is a potent anti-cancer agent in numerous human cancer cell lines. The safety of administrating CVM-1118 on human is evaluated from the phase 1 study. The objectives of the phase 2 study is to further investigate the efficacy of CVM-1118 for patients with advanced neuroendocrine tumors.
Neuroendocrine tumors of the lung include the small cell carcinoma (SCLC), and large cell neuroendocrine carcinoma (LCNEC) and represent 20% of lung cancer. One of the only studies reported to date is reporting on a progression-free survival (PFS) and overall survival (OS) of 5.2 months and 7.7 months, respectively. Poorly differentiated gastroentero-pancreatic neuroendocrine carcinomas (GEP-NEC) represent a small sub-group of digestive NENs, according to the studies, 7 to 21% of patients. However, their prognosis is more negative, with the 5-year survival at less than 20%. Many Phase III trials showed superiority in terms of efficacy and tolerance of nivolumab+/-ipilimumab versus standard chemotherapy in second-line treatment in metastatic solid tumors. Neuroendocrine tumors are considered as rare disease without therapeutic guidelines in this setting. The French academic oncology groups (IFCT, FFCD and GERCOR) have the opportunity to recruit a sufficient number of patients, in a reasonable period of time, to provide a proof-of-concept of the safety and efficacy of nivolumab+/-ipilimumab in this population.
This phase Ib trial studies how well pembrolizumab works with combination chemotherapy in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate that has spread to nearby tissue or lymph nodes or that has spread to other places in the body. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as etoposide, docetaxel, cisplatin, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving pembrolizumab with platinum-based chemotherapy may work better in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate.
This is a Phase 1, multiple dose, ascending dose escalation study to define a MTD/RD and regimen of XmAb20717, to describe safety and tolerability, to assess PK and immunogenicity, and to preliminarily assess anti-tumor activity of XmAb20717 in subjects with selected advanced solid tumors.
