Active clinical trials for "Adenocarcinoma"

The purpose of this study is to evaluate the safety, dose, immunogenicity and early clinical activity of GRT-C901 and GRT-R902, a personalized neoantigen cancer vaccine, in combination with nivolumab and ipilimumab, in patients with metastatic non-small cell lung cancer, microsatellite stable colorectal cancer, gastroesophageal adenocarcinoma, and metastatic urothelial cancer.

Hypofractionated external beam radiotherapy has been clinically used for localized prostate cancer in view of the low estimated alpha/beta ratio of prostate cancer cells. Moderate fraction sizes of <4Gy per fraction has been investigated in several phase II/III studies and has been found to be well tolerated with comparable biochemical control in comparison with standard fractionated dose-escalated regimens. Fraction sizes of > 4 Gy has also been investigated in single center studies. However, its toxicity and disease control outcomes is less well known. In this Phase I/II single arm study the investigators aim to treat non-metastatic prostate cancer with stageT1-T4N0M0 and Prostate Specific Antigen (PSA) <60 ng/ml to a regimen of 35Gy in 5 fractions delivered once a week with a view to determine acute toxicity, biochemical control with PSA and late toxicity.

This phase I trial studies how well stereotactic body radiation therapy works in combination with tremelimumab and durvalumab in treating participants with cervical, vaginal, or vulvar cancers that have come back (recurrent) or spread to other areas of the body (metastatic). Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Immunotherapy with monoclonal antibodies, such as tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving stereotactic body radiation therapy, tremelimumab, and durvalumab may work better in treating participants with cervical, vaginal, or vulvar cancers.

Gastro-esophageal adenocarcinoma is one of the most common cancer in the world and the fourth most common cancer in France with more than 6,000 cases per year. For non-metastatic patients, a preoperative chemotherapy is recommended. As colorectal adenocarcinomas, gastroesophageal cancers (OGC) could be caused by a failure of DNA repair related to the loss of expression of one of the DNA repair proteins (MLH1, MSH2, PMS2, MSH6) (deficient MMR (dMMR)). The prevalence of tumors with dMMR is evaluated at 14% (Choi et al, 2014; Kim et al, 2015). This proportion reaches 25% among patients over 70 years old. Evidence suggests that patients with dMMR tumors do not benefit from neoadjuvant chemotherapy (Smyth et al, 2017), which may even have a negative impact, especially in elderly patients, and which should be discussed in this particular situation. The decision of neo-adjuvant chemotherapy must be taken very quickly after the endoscopic diagnosis. The investigators will evaluate the diagnostic performance of the determination of dMMR status by endoscopic biopsies of OGC. Moreover, there is no clear recommendation for the determination of dMMR status in OGC especially regarding the size of the forceps to use to ensure the quality of samples and the best molecular techniques for dMMR status determination. Methods In this prospective study, the investigators will include patients who will benefit from an upper endoscopy within 5 French hospital centers (Saint-Louis, Lariboisière, Beaujon, Bichat and Avicenne) linked to the NORDICAP network. If a suspect lesion of OGC is discovered during the gastroscopy, the endoscopist will perform at least 8 endoscopic biopsies, according to the recommendations, and by the mean of 2 kinds of forceps: standard biopsy forceps and a large capacity biopsy forceps. The clinical and follow-up data will be prospectively collected and will include demographics data, cancer stage, lymph node invasion, treatment history, recurrence and survival data. The investigators will assess MSI status by genotyping and MMR proteins expression by immunochemistry (IHC), performed, for each patient, on both biopsies and surgical tumor samples. Expected results This study will allow us to compare diagnostic performance of endoscopic biopsies to surgical samples for the assessment of dMMR status. Likewise, the investigators will compare the diagnostic performance of the two kinds of endoscopic forceps and of IHC and genotyping for the determination of dMMR phenotype. It will enable us to establish recommendations for the benefit of gastro-enterologists and pathologists.

The purpose of this clinical trial is to study an experimental drug called PTP-01 that is being used as an imaging agent to diagnosis pancreatic cancer. Currently, pancreatic cancer is diagnosed using CT or MRI scans which miss small pancreatic cancers, particularly early stage disease. Researchers at the University of Virginia have identified a biomarker for pancreatic cancer called plectin, which is very specific for pancreatic cancer and not other, non-cancerous conditions involving the pancreas. These researchers have also developed PTP-01, an experimental drug that may be used with SPECT imaging to detect pancreatic cancer cells in humans.

This phase II trial studies how well cabozantinib-s-malate works in treating patients with ovarian, fallopian tube, or primary peritoneal cavity cancer that has come back or is growing, spreading, or getting worse. Cabozantinib-s-malate may stop the growth of tumor cells by blocking the growth of new blood vessels necessary for tumor growth and also by blocking some of the enzymes needed for cell growth.

Famitinib is a tyrosin-inhibitor agent targeting at c-Kit, VEGFR2, PDGFR, VEGFR3, Flt1 and Flt3, whose anti-tumor and anti-angiogenesis effects have been validated in preclinical tests. In PhaseⅡb study, a significantly improved Progression Free Survival (PFS) was found in patients with advanced colorectal cancer treated with Famitinib compared to placebo. On the other hand, the toxicity of Famitinib was manageable in both PhaseⅠand Ⅱb studies. The purpose of this study is to determine whether Famitinib can improve Overall Survival (OS) compared with placebo in total 540 patients with advanced colorectal cancer who have failed in previously received at least two lines of standard chemotherapy.

This pilot early phase I trial studies talazoparib to determine if certain characteristics of the deoxyribonucleic acid (DNA) affect how the disease responds to therapy in patients with ovarian, fallopian tube, or primary peritoneal cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment (advanced). Studying samples of tissue in the laboratory from patients receiving talazoparib may help doctors learn more about the effects of talazoparib on cells and may help doctors understand how well patients respond to treatment.

The investigators' long-term goal is to improve the survival of patients with pancreatic cancer by enhancing the efficacy of gemcitabine-radiation by adding the Wee1 inhibitor MK-1775.

This pilot clinical trial studies 6,8-bis(benzylthio)octanoic acid in treating patients with locally advanced or metastatic pancreatic cancer. Drugs used in chemotherapy, such as 6,8-bis(benzylthio)octanoic acid, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
