Background: During recent years, cancer-testis (CT) antigens (CTA), particularly those encoded by genes on the X chromosome (CT-X genes), have emerged as attractive targets for cancer immunotherapy. Whereas malignancies of diverse histologies express a variety of CTAs, immune responses to these proteins appear uncommon in cancer patients, possibly due to low-level, heterogeneous antigen expression, as well as immunosuppressive regulatory T cells present within tumor sites and systemic circulation of these individuals. Conceivably, vaccination of cancer patients with tumor cells expressing high levels of CTAs in combination with regimens that deplete or inhibit T regulatory cells will induce broad immunity to these antigens. In order to examine this issue, patients with primary lung and esophageal cancers, pleural mesotheliomas, thoracic sarcomas, thymic neoplasms and mediastinal germ cell tumors, as well as sarcomas, melanomas, germ cell tumors, or epithelial malignancies metastatic to lungs, pleura or mediastinum with no evidence of disease (NED) or minimal residual disease (MRD) following standard multidisciplinary therapy will be vaccinated with H1299 tumor cell lysates with Iscomatrix adjuvant. Vaccines will be administered with or without metronomic oral cyclophosphamide (50 mg by mouth (PO) twice a day (BID) x 7day (d) every (q) 14d), and celecoxib (400 mg PO BID). Serologic responses to a variety of recombinant CTAs as well as immunologic responses to autologous tumor or epigenetically modified autologous Epstein-Barr virus (EBV) transformed lymphocytes will be assessed before and after a six month vaccination period. Primary Objectives: 1. To assess the frequency of immunologic responses to CTAs in patients with thoracic malignancies following vaccinations with H1299 cell lysate/Iscomatrix(TM) vaccines alone in comparison to patients with thoracic malignancies following vaccinations with H1299 cell lysate/Iscomatrix vaccines in combination with metronomic cyclophosphamide and celecoxib. Secondary Objectives: 1. To examine if oral metronomic cyclophosphamide and celecoxib therapy diminishes the number and percentage of T regulatory cells and diminishes activity of these cells in patients with thoracic malignancies are at risk of recurrence. 2. To examine if H1299 cell lysate/Iscomatrix(TM) vaccination enhances immunologic response to autologous tumor or epigenetically modified autologous EBV-transformed lymphocytes (B cells). Eligibility: - Patients with histologically or cytologically proven small cell or non-small cell lung cancer (SCLC;NSCLC), esophageal cancer (EsC), malignant pleural mesothelioma (MPM), thymic or mediastinal germ cell tumors, thoracic sarcomas, or melanomas, sarcomas, or epithelial malignancies metastatic to lungs, pleura or mediastinum who have no clinical evidence of active disease (NED), or minimal residual disease (MRD) not readily accessible by non-invasive biopsy or resection/radiation following standard therapy completed within the past 26 weeks. - Patients must be 18 years or older with an Eastern Cooperative Oncology Group (ECOG) performance status of 0 - 2. - Patients must have adequate bone marrow, kidney, liver, lung and cardiac function. - Patients may not be on systemic immunosuppressive medications at time vaccinations commence. Design: - Following recovery from surgery, chemotherapy, or chemo/radiotherapy (XRT), patients with NED or MRD will be vaccinated via IM injection with H1299 cell lysates and Iscomatrix(TM) adjuvant monthly for 6 months. - Vaccines will be administered with or without with metronomic oral cyclophosphamide and celecoxib. - Systemic toxicities and immunologic response to therapy will be recorded. Pre and post vaccination serologic and cell mediated responses to a standard panel of CT antigens as well as autologous tumor cells (if available) and EBV-transformed lymphocytes will be assessed before and after vaccination. - Numbers/percentages and function of T regulatory cells in peripheral blood will be assessed before, during, and after vaccinations. - Patients will be followed in the clinic with routine staging scans until disease recurrence. - The trial will randomize 28 evaluable patients per arm to either receive vaccine alone or vaccine plus chemotherapy in order to have 80% power to determine if the frequency of immune responses on the combination arm exceeds that of the vaccine alone arm, if the expected frequencies of immune responses on the two arms were 20% and 50%, using a one-sided 0.10 alpha level Fisher's exact test. - Approximately 60 patients will be accrued to this trial.
Cancer patients have an increased risk of developing blood clots in the veins compared to non-cancer patients. Cancer patients who develop blood clots can lead to reduced life expectancy, delayed cancer treatment, and decreased quality of life. Prevention is the most effective way to decrease the complications associated with blood clots in the veins. Although previous clinical trials have shown some benefit on the use of medication to prevent blood clots in the veins in ambulatory cancer patients, these studies have been inconclusive in demonstrating that existing blood thinners significantly reduce the rate of blood clots in cancer patients. One possible explanation relates to the fact that these studies have included a large proportion of cancer patients who are a low risk of developing blood clots in the veins. We are proposing to identify cancer patients who are at a high risk of developing blood clots by using a validated tool at the time of their cancer diagnosis. The identified high risk cancer patients will be asked to participate in a trial to test the safety and efficacy of a new oral medication that has been used to prevent blood clots in patients undergoing surgery. We are enrolling 574 patients in 7 Canadian centers (Ottawa, Halifax, Montreal, Vancouver, Sault Ste. Marie, Toronto and Hamilton). 287 patients will receive the study drug and 287 will receive an inactive substance. Analysis will be performed to assess the safety and the superiority of the study drug.
ACT-PFK-158 is a novel anti-cancer agent that inhibits glucose uptake in cancer cells. The primary objective of the study will be to determine the maximum tolerated dose (MTD) and to describe any dose limiting toxicity. The secondary objectives of the study will be to determine the safety profile of the drug, to determine the pharmacokinetic profile, to identify any anti-tumor activity, and to determine the pharmacodynamic profile of ACT-PFK-158.
The goal of this study is to determine the feasibility, reliability, and validity of administering the Geriatric Assessment Tool using these two different computer based survey platforms, REDCap and Support Screen. The development of a computer based Geriatric Assessment Tool has the potential to improve research and clinical practice by providing an efficient user friendly means to collect and analyze data for geriatric oncology patients.
This study is being conducted to measure the relative bioavailability of the original gelatin capsule formulation and a new formulation, immediate release (IR) tablet of Afuresertib (GSK2110183). The study will be composed of Screening, Treatment, and Follow-up Periods. A subject's total time involved in the study will be approximately 9 weeks. The study will enroll approximately 18 healthy volunteers.
This is an observational study. The purpose is to determine the feasibility of using a novel nano-scintillator fiber-optic dosimeter (nanoFOD) for the real time dosimetric monitoring of brachytherapy treatment. Women with gynecologic cancers treated with brachytherapy as part of their standard therapeutic regimen will represent the study population.
The purpose of this study is to determine if Gadofosveset Trisodium (Gdfos, Ablavar) is a useful magnetic resonance imaging (MRI) contrast agent in accurately diagnosing liver metastases compared to the standard agent gadobutrol (EcGd, Gadovist).
The objective of the study is to evaluate the efficacy of the Pac-IFicO programme in improving the quality of pain management in hospitalised cancer patients. This is a before-after cluster phase II study performed in medicine, oncology and respiratory disease hospital wards. The Pac-IFicO programme is a complex interventions with multiple components. The primary end-point of the study is the proportion of cancer patients with severe pain.
The EndoCuff is novel flexible cuff that can be attached to the distal tip of the colonoscope and helps to flatten large mucosal folds during withdrawal. The study hypothesis is that the use of the Endocuff (EC) increases the adenoma detection rate during colonoscopy. The study purpose is to compare EC-assisted colonoscopy with standard colonoscopy for polyp detection.
