A multi-institutional, single arm pilot study of antibiotics and pembrolizumab, following chemotherapy for the treatment of surgically resectable pancreatic cancer.
The goal of this clinical trial is to learn if Adaptive Radiation Therapy (ART) is safe and effective in treating patients with locally advanced pancreatic cancer.
The main questions the study aims to answer are:
* Can ART improve how well radiation therapy targets the most aggressive cancer cells, while protecting the healthy tissue around the tumor?
* Can ART help reduce the side effects that participants may experience during treatment?
Participants will:
* Undergo CT scans to plan the exact location of the radiation treatment. During this process, 1-3 small markers may be placed in or near the tumor to help with the planning.
* Have a tumor biopsy, which involves taking a small sample of tissue from the cancer.
* Receive 5 radiation treatments every other day over a 2-week period.
* Provide blood samples before, during, and after your radiation treatment.
Replication-competent Adenovirus-mediated Double Suicide Gene Therapy (Theragene®,Ad5-yCD/mutTKSR39rep-ADP) showed safety and anti-cancer effect in patients with pancreatic cancer in phase I study.
From the experience of phase I study, the safety and efficacy of combination with standard chemotherapy and radiation therapy with Theragene treatment will be assessed in this study.
The primary purpose of this study is to evaluate the safety, side effects, and dosage for Motexafin Gadolinium given with the chemotherapy drug docetaxel to patients with advanced cancers. Secondly, tumor response to the combined treatment, drug levels in the body, and drug interactions will be evaluated.
This study aims to examine technical feasibility and diagnostic yield of new 20-gauge Procore needle for EUS-guided fine needle biopsy in solid lesions by comparing with 22-gauge Procore needle. The study design is prospective, randomized study.
This phase I trial studies the side effects and best dose of vaccine therapy when given together with sargramostim in treating patients with locally advanced or metastatic pancreatic cancer that cannot be removed by surgery. Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells. Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood. Giving vaccine therapy directly into the tumor together with sargramostim may cause a stronger immune response and kill more tumor cells.
This study is open to adults with advanced cancer of the colon, rectum, stomach, or pancreas, that is the cancer cannot be removed by surgery or has spread. People can take part in this study if their previous treatment was not successful, or no other treatment exists.
The study aims to find the highest dose for the study medicine called BI 765049 that people with advanced cancer can tolerate. Another purpose is to find the most suitable dose and best way of administration of BI 765049 for further clinical development. BI 765049 may help the immune system fight cancer.
Participants receive BI 765049 at least once every 3 weeks. Participants may continue to get BI 765049 treatment as long as they benefit from treatment and can tolerate it.
During this time, participants regularly visit the study site. The study visits include several overnight stays at the hospital. At the visits, study doctors check participants' health, take necessary laboratory tests, and note any unwanted effects. Unwanted effects are any health problems that the doctors think were caused by the study medicine or treatment. To find the highest dose of BI 765049 that participants can tolerate, researchers look at the number of participants with certain severe health problems. These are severe health problems that happen within 1 week after the first treatment with the intended dose.
The main purpose of this first human study with CC-223 is to assess the safety and action of a new class of experimental drug (dual mTOR inhibitors) in patients with advanced tumors unresponsive to standard therapies and to determine the appropriate dose and tumor type for later-stage clinical trials.
Pancreatic cancer (PC) is one of the deadliest diseases of human digestive malignancies. Despite the recent advances in surgery and chemotherapy, the 5-year survival rate of PC continues to be less than 10%. As a promising tumor therapy,Chimeric antigen receptor T cell (CAR-T), however, performed poorly in PC treatment and need to be further updated. In our study, on the basis of our previous research, we use anti-MSLN CAR-T as effector cell and explore the different effects and mechanism of gut microbiota (PC or healthy control) on anti-MSLN CAR-T treatment. Firstly, we detect the differences of gut microbiota and T cell cholesterol metabolism in PC and healthy control by means of 16S-rRNA,PCR, western blot and ELISA; explore the different effects of gut microbiota on the subtype of T cells; and analyze the relationships between intestinal flora composition and T cell cholesterol metabolism or subtype changes by means of Spearman's correlation. Secondly, we also explore the different effects of gut microbiota on the proliferation, migration, subtype, inflammatory cytokines expression and anti-tumor effector function of anti-MSLN CAR-T cells by means of flow cytometry and cytotoxicity assay. Thirdly, we discuss the different expression of cholesterol esterification enzyme 1 (ACAT-1) and other core genes of cholesterol metabolism in anti-MSLN CAR-T. Lastly, we evaluate the effects of different gut microbiota on the treatment of PC by anti-MSLN CAR-T cells in NSG mouse model of subcutaneous PC transplantation and liver metastasis. Through the above experiments, a new theoretical basis is provided in which gut microbiota regulates the subtype and anti-tumor function of anti-MSLN CAR-T by ACAT-1 expression. Furthermore, our findings, which demonstrate the relationship of gut microbiota and CAR-T cell, may be translatable for the treatment of other solid tumors like PC.
This is an open-label, multi-center, multi-national, non-randomized rollover study designed to allow continued access to napabucasin for patients who have participated in a Boston Biomedical-sponsored study and are being treated with napabucasin (monotherapy or combination) and who are deriving continued clinical benefit in the parent study at the time of closure.
