Advanced Pancreatic Adenocarcinoma

ClinicalTrials.gov Brief Summary This Phase 1, open-label, first-in-human study is designed to evaluate the safety, tolerability, and recommended dose of intraperitoneal (IP) administration of Lm-LLO-TT in combination with low-dose gemcitabine in adults with previously treated, unresectable or metastatic pancreatic ductal adenocarcinoma (PDAC). Up to 18 participants will be enrolled. Lm-LLO-TT is a live attenuated Listeria monocytogenes-based immunotherapy engineered to express a tetanus toxoid antigen. The study will assess the safety of administering Lm-LLO-TT directly into the peritoneal cavity and characterize its use in combination with low-dose gemcitabine. Eligible participants will receive a tetanus toxoid booster vaccination during screening and undergo placement of an intraperitoneal access port before treatment. Participants will receive a single loading dose of Lm-LLO-TT followed by five cycles of low-dose gemcitabine and low-dose Lm-LLO-TT administered over approximately 17 days. Participants will be monitored for adverse events, laboratory abnormalities, dose-limiting toxicities, and disease outcomes throughout the study. The primary objective is to assess safety and tolerability and to determine the maximum tolerated dose and recommended dose for future clinical studies. Secondary objectives include evaluation of anti-tumor activity. Exploratory objectives include assessment of immune biomarkers, changes in pancreatic cancer-related symptoms, and changes in pain medication use. Participants will undergo tumor imaging assessments following treatment and during follow-up. A post-treatment tumor biopsy will be required for the first 10 enrolled participants and optional for subsequent participants. Participants will be followed for safety, disease status, and survival for up to 6 months after treatment initiation.

The UNCOVER study is a longitudinal observational cohort focused on patients at high risk for cancer cachexia. At Kaiser Permanente Northern California, up to 800 individuals with advanced or unresectable non-small cell lung cancer, pancreatic adenocarcinoma, or colorectal cancer will be enrolled, as these malignancies carry a substantial risk of cancer cachexia, which is characterized by progressive loss of weight, muscle, and adipose tissue, accompanied by functional decline and reduced quality of life. Data collected includes demographic, physiologic, and clinical data, including tumor characteristics and biomarkers of inflammation, hormonal and metabolic status, body composition, physical function, and patient reported outcomes. Investigators will identify patient phenotypes (i.e., subgroups) that may reflect distinct biological or clinical pathways underlying cancer cachexia. By characterizing heterogeneity in cancer cachexia, this study aims to inform the development of improved diagnostic criteria and more targeted therapeutic strategies, ultimately enhancing clinical trial design and supportive care for patients with advanced colorectal, lung, or pancreatic cancer.

The goal of this clinical trial is to evaluate the safety and preliminary effectiveness of a new combination therapy in patients with advanced pancreatic cancer. The main questions it aims to answer are: 1. Is the combination of the peptide nanovaccine (ONVAX-01), an anti-PD-1 antibody, and chemotherapy safe and well-tolerated? 2. Does this combination treatment help shrink tumors or stop the progression of advanced pancreatic cancer? Participants will be asked to: 1. Receive doses of the peptide nanovaccine (ONVAX-01). 2. Receive intravenous infusions of an anti-PD-1 antibody and standard chemotherapy. 3. Undergo regular physical exams, blood tests, and imaging scans (such as CT or MRI) to monitor their health and the tumor's response to the treatment.

This research study is being done to help determine the safety and efficacy of gadolinium based nanoparticle, Activation and Guidance of Irradiation X (AGuIX), used in conjunction with MR-guided stereotactic body radiation therapy (SBRT) in the treatment of pancreatic cancer and lung tumors.

This phase Ib trial tests the safety, side effects, and best dose of leflunomide in combination with gemcitabine in treating patients with pancreatic cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and cannot be removed by surgery (unresectable). Improving the effectiveness of gemcitabine without increasing side effects could lead to a greater impact for pancreatic cancer patients' survival and quality of life. Gemcitabine is commonly used as a first-line chemotherapy treatment for pancreatic cancer. Leflunomide is a drug approved for use against rheumatoid arthritis that is being looked at as a cancer treatment option. It has shown promising results when combined with gemcitabine. Giving gemcitabine in combination with leflunomide may be safe and effective in treating patients with advanced unresectable pancreatic cancer.

This study evaluates cancer-related weight and muscle mass loss, symptoms, and physical function (cachexia) in patients undergoing treatment for colorectal, lung, or pancreatic cancer that cannot be removed by surgery (unresectable) or is stage IV. Patients with these cancer types are at risk for developing cancer cachexia (CC), which is defined as weight loss, muscle loss, and fat loss due to cancer. CC has been associated with reduced physical performance, impaired quality of life, and poorer survival. Many studies that have evaluated treatments for cancer-related weight and muscle loss have aimed to treat all patients with weight loss exactly the same and, unfortunately, have not been successful. Like different cancer types, weight and muscle loss related to cancer may have different causes in different individuals and the best treatment strategy for this condition may not be a one-size-fits-all approach. Information gathered from this study may help researchers develop new diagnostic criteria for CC and design better treatments and clinical trials for cancer-related weight and muscle loss in the future to improve the quality of life in patients with advanced colorectal, lung, or pancreatic cancer.
