Active clinical trials for "Adenocarcinoma"

The main purpose of this study is to see how pancrelipase affects the body mass index (BMI) in people with metastatic PDAC. BMI is a measure based on a person's height and weight. Other study goals are to explore two different dosing schedules of pancrelipase and to evaluate pancrelipase in people who do not have symptoms of EPI.

This study is a non-randomized, open-label, multi-cohort, multi-site, pilot feasibility therapeutic trial. The study will enroll 20 patients across 4 cohorts (CRC, gastric, PDAC, and HCC/intra-hepatic-/extra-hepatic-, gall bladder adenocarcinomas) diagnosed with histologically confirmed GI cancers. These patients will have already completed all Standard of Care (SOC) treatments (including neoadjuvant, surgery, local therapies, and/or adjuvant therapy as applicable), as defined by the treating primary physician or research team, with curative intent but have a positive SignateraTM tumor-informed ctDNA test and NED radiographically by standard imaging within 28 days prior to enrollment and within 1 year of completing all curative-intent therapy. All patients will be treated with intravenous (IV) atezolizumab 1200 mg IV and bevacizumab 15 mg/kg on Day 1 of 21-day cycles until disease recurrence, ctDNA POD, unacceptable toxicity, or subject withdrawal of consent with a maximum 12 month total duration of study therapy. Atezolizumab and bevacizumab drug will be provided.

The ADCI 002 trial is a large multicenter phase II-III prospective randomized controlled trial comparing primary surgery versus primary chemotherapy followed by surgery in patients with a resectable signet ring cell gastric adenocarcinoma

The investigators hypothesize that detection of field cancerization in the GI tract could be performed during endoscopy by performing Raman and scattering measurements. Together with the Technical University of Munich (TUM) and the Universidad Carlos III de Madrid (UC3M), the investigators have developed an investigational medical device that integrates probe-based Raman and scattering measurements for endoscopic purposes: the SENSITIVE system. During preclinical ex vivo studies, the investigators have established that measurements of the SENSITIVE system were able to discriminate between non-field cancerized tissue and field cancerized tissue. Considering these results, the investigators aim to assess the safety of in vivo Raman/scattering during endoscopy. Secondly, the investigators to assess the feasibility of this approach measurements to determine field cancerization in the alimentary tract during endoscopy through the SENSITIVE system.

This clinical trial studies the effects of a diet and physical activity intervention on blood measures of lipids and insulin resistance in patients with prostate cancer undergoing radiation therapy (RT) and androgen deprivation therapy (ADT). ADT effectively slows the growth of prostate cancer cells, thereby enhancing the therapeutic effectiveness of RT. Despite the clinical gains, ADT leads to an array of side effects including insulin resistance, abnormal lipid levels, weight gain, increased visceral fat mass coupled with increased muscle wasting, and quality of life deterioration. A diet and physical activity intervention may intercept or prevent the abrupt metabolic and physiologic changes caused by androgen deprivation therapy in prostate cancer patients receiving ADT and RT.

The main objective is the evaluation of the prognostic value of ctDNA (circulating tumor DNA) as a marker of surgical futility in patients with operable PDAC.

The purpose of this research study is to learn about the best approach to sample patients with known or suspected Barrett's esophagus (BE) by comparing the standard Seattle biopsy protocol to sampling using wide area transepithelial sampling (WATS3D). Barrett's esophagus is a common condition that is used to spot patients at increased risk of developing a type of cancer in the esophagus (swallowing tube) called esophageal adenocarcinoma. The 5-year survival rate is as low as 18% for patients who get esophageal adenocarcinoma, but the rate may be improved if the cancer is caught in its early stages. Barrett's esophagus can lead to dysplasia, or precancerous changes, which occurs when cells look abnormal but have not developed into cancer. If the abnormal cells increase from being slightly abnormal (low-grade dysplasia), to being very abnormal (high-grade dysplasia), the risk of developing cancer (esophageal adenocarcinoma) goes up. Therefore, catching dysplasia early is very important to prevent cancer. Endoscopic surveillance is a type of procedure where endoscopists run a tube with a light and a camera on the end of it down a patients throat and remove a small piece of tissue. The piece of tissue, called a biopsy, is about the size of the tip of a ball-point pen and is checked for abnormal cells and cancer cells. Patients are being asked to be in this research study because they have been diagnosed with BE or suspected to have BE, and will need an esophagogastroduodenoscopy (EGD). Patients with BE undergo sampling using the Seattle biopsy protocol during which samples are obtained from the BE in a four quadrant fashion every 2 cm along with target biopsies from any abnormal areas within the BE. Another sampling approach is WATS3D which utilizes brushings from the BE. While both of these procedures are widely accepted approaches to sampling patients with BE during endoscopy, there is not enough research to show if one is better than the other. Participants in this study will undergo sampling of the BE using both approaches (Seattle biopsy protocol and WATS-3D); the order of the techniques will be randomized. Up to 2700 participants will take part in this research. This is a multicenter study involving several academic, community and private hospitals around the country.

The aim of this study is to assess the clinical value of 5 transcriptomic signatures prognostic of chemotherapeutic sensitivity to improve the Objective Response Rate (ORR) of first-line (L1). Chemotherapy regimen (FOLFIRINOX vs Gem-nabP) will be selected based on transcriptomic signatures applied to the pre-therapeutic liver biopsy of newly diagnosed PDAC patients.

This study is an open, exploratory clinical study. Eligible patients with advanced second-line gastric/gastroesophageal junction adenocarcinoma signed an informed consent form, were screened for enrollment, and were entered into Group A (non-immune retreatment group-patients who had failed previous first-line treatment with standard chemotherapy) and Group B (immune retreatment-patients who had obtained SD and above with best efficacy of previous first-line treatment with PD-1 antibody) based on whether they had received previous first-line treatment with PD-1 antibody. All patients received a combination of envafolimab and lenvatinib in combination with paclitaxel-albumin and were treated until disease progression, withdrawal of informed consent by the subject, loss to follow-up, and death, where treatment did not exceed 2 years. Clinical oncologic imaging assessments were performed using iRECIST every 8 weeks during treatment; safety assessments were performed using CTCAE 5.0, and adverse events were recorded throughout the study up to 30 days after the end of treatment.

The goal of this research study is to determine whether hormonal therapies used early in the course of prostate cancer could increase the amount of Prostate-Specific Membrane Antigen (PSMA) as detected by PET/CT scans for participants with recurrent prostate cancer. This study will measure PSMA levels using standard PET/CT scans and participants will receive standard-of-care androgen receptor antagonist monotherapy. The names of the treatment interventions involved in this study are: Androgen receptor antagonist monotherapy. PSMA PET/CT scan It is expected that about 15 people will take part in this research study. Participation in this research study is expected to last about 4 weeks.
