Filter by:This study is being conducted to assess the safety, tolerability, and efficacy of EDP1503 alone and in combination with pembrolizumab in patients with advanced metastatic colorectal carcinoma, triple-negative breast cancer, and checkpoint inhibitor relapsed tumors
The purpose of this study is to find out what effects durvalumab has on bladder cancer, combined with treatment after completion of surgery, chemotherapy and radiotherapy.
This study evaluates the clinical benefit of TAS-102 in participants with metastatic urothelial carcinoma who are resistant to cisplatin or carboplatin front-line and checkpoint inhibitors as second line therapy. All participants will receive TAS-102 in oral form twice per day on Days 1-5 and Days 8-12 of each 28 day cycle.
Research Hypothesis Approximately 75% of patients with bladder cancer (BC) present with a disease confined to the mucosa (stage Ta, CIS) or submucosa (stage T1) (non-muscle invasive BC [NMIBC]). For high grade NMIBC, i.e. TaG3, T1G3 and CIS, intravesical bacillus Calmette-Guérin (BCG) immunotherapy is the treatment of choice, given that it prevents recurrence and reduces the odds of progression to MIBC. However, since initial BCG therapy fails in approximately 40% of patients over a 2-year period, new treatment options for these patients are of utmost importance. In that field of research durvalumab, a human monoclonal antibody that binds programmed cell death ligand-1 (PD-L1), demonstrated meaningful clinical activity as well as manageable safety profile in PD-L1-positive patients with BC, many of whom were heavily pretreated. Certain studies using systemic administration of anti-PD1 agents for BCG refractory NMIBC are ongoing. Nevertheless, intravesical administration may be advantageous, since selective bladder tumor uptake of monoclonal antibodies following intravesical administration, while this method results in negligible absorption in the circulation and, therefore, minimal risk of systemic toxicity. This notion is supported by the findings of a recent study of intravesical administration of recombinant adenovirus-mediated interferon-α2b gene therapy (rAd-IFNα), No rAd-IFNα DNA was detected in the blood. Furthermore, no systemic toxicity was reported in a phase II study using the same agent. The investigators, therefore, propose a phase II study of intravesical administration of durvalumab in patients with BCG refractory NMIBC. Since no safety or efficacy data specifically on intravesical administration of durvalumab exist, a run-in part will precede the main phase II, in order to confirm safety of the procedure and to reject a futility hypothesis, as described in the following sections of the protocol. Correlative studies of potential biomarkers in tumor tissue before and after durvalumab instillation are also proposed.
A multidisciplinary approach has led to the development of bladder-preservation therapy using maximal transurethral resection followed by radiotherapy with concomitant radio-sensitizing chemotherapy for muscle-invasive bladder cancer.
This research study is studying the effects of adding a certain type of immunotherapy to standard bladder-directed radiation as a treatment for muscle-invasive urothelial carcinoma of the bladder. The drug in this study is: Avelumab (also known as BAVENCIO®)
This study is a first in human Phase 1 study that involves patients with a type of cancer called HER2 (Human Epidermal Growth Factor Receptor 2) positive cancer. This study asks patients to volunteer to take part in a research study investigating the safety and efficacy of using special immune cells called HER2 chimeric antigen receptor specific cytotoxic T lymphocytes (HER2 specific CAR T cells), in combination with intra-tumor injection of CAdVEC, an oncolytic adenovirus that is designed to help the immune system including HER2 specific CAR T cell react to the tumor. The study is looking at combining these two treatments together, because we think that the combination of treatments will work better than each treatment alone. We also hope to learn the best dose level of the treatments and whether or not it is safe to use them together. In this study, CAdVEC will be injected into participants tumor at one tumor site which is most easiest to reach. Once it infects the cancer cells, activation of the immune response will occur so it can attack and kill cancer cells. (This approach may have limited effects on the other tumor sites that have not received the oncolytic virus injection, so, patients will also receive specific T cells following the intratumor CAdVEC injection.) These T cells are special infection-fighting blood cells that can kill cells infected with viruses and tumor cells. Investigators want to see if these cells can survive in the blood and affect the tumor. Both CAdVEC and HER2-specific autologous CAR T are investigational products. They are not approved by the FDA.
Millions of cancer patients every year receive chemotherapy with only a 20-60% probability of pathological response, while most experience adverse side effects that lower quality of life without prolonging it. Reliable identification of ineffective therapies can eliminate needless human suffering while increasing overall probability of positive response to treatment. Chemotherapy resistance profiling entails testing whether a patient exhibits strong resistance to a therapy prior to its final selection by the oncologist. However, there are no effective methods for quickly assessing patient chemotherapy resistance. Patient Derived Xenograft (PDX) models have replaced older Chemotherapy Sensitivity and Resistance Assays (CSRAs) to some degree, but both technologies suffer from long testing times, high cost, and/or low accuracy. Motility Contrast Tomography (MCT) has recently emerged as a technology that measures the biodynamic response of intact tumor biopsies to applied therapeutics by using Doppler detection of infrared light scattered from intracellular motions inside living tissue. Several small scale animal, xenograft, and human studies have shown this phenotypic profiling technique to be highly accurate in prediction of response and resistance to chemotherapy. This project will be the first human trial of biodynamic phenotyping to predict chemotherapy response among bladder cancer patients. Specifically, the study cohort will include patients selected for neoadjuvant chemotherapy treatment, because this setting offers the opportunity for near-term outcome measurement at the time of post-chemo surgery. Pre-therapy fresh tumor specimens will be imaged using MCT, and the resulting bio-dynamic signatures will be compared to confirmed pathological response at the time of surgery. Observation of a high predictive value will provide the basis for expanded clinical trials and prompt commercialization of a biodynamic chemotherapy selection assay for bladder and other cancer patients.
Based on current evidence, we hypothesize that eTURB represents an improvement in the surgical management of NMIBC. The resection is more precise and complete compared to cTURB. Moreover, the quality of an en-bloc specimen, including the tumor with its adjacent bladder wall layers, allows an accurate pathological review which leads to correct risk allocation and therapy. To answer these questions, we designed a RCT comparing eTURB with cTURB. Primary outcome of our study will be the accuracy of pathological staging assessment measured by the presence of detrusor muscle in the specimen as a surrogate parameter for quality of resection.
This prospective interventional study aims at evaluating the safety and efficacy of an adjuvant radiation treatment in cases of muscle-invasive bladder cancer, submitted to radical cystectomy and presenting clinic-pathological characteristics of high risk of recurrence.
