Stomach Cancer clinical trials at University of California Health

The goal of this clinical trial is to test the safety and efficacy of KVA12123 alone or combined with pembrolizumab in patients with advanced solid tumors. The main questions this study aims to answer are: 1. What is the safety of KVA12123 when administered alone and in combination with pembrolizumab to advanced cancer patients? 2. What is an appropriate dose of KVA12123 to administer alone and in combination with pembrolizumab to advanced cancer patients in future clinical trials? Participants in this trial will be asked to: 1. Visit the clinical site every 1 - 2 weeks. 2. Receive KVA12123 every 2 weeks alone or in combination with pembrolizumab every 6 weeks. 3. Provide blood samples to evaluate drug levels in blood, drug safety and to explore the effects of each drug on the immune system. 4. Undergo scans every 6 weeks to test the effect of treatment on cancer progression. 5. Undergo other study procedures to evaluate drug safety and participant safety including physical exams, heart function tests, etc.

Claudin 18.2 protein, or CLDN18.2 is a protein found on cells in the digestive system. It is also found on some tumors. Researchers are looking at ways to attack CLDN18.2 to help control tumors. ASP2138 is thought to bind to 2 targets at the same time: CLDN18.2 and a protein called CD3 found on immune cells, called T-cells. ASP2138 works by binding to both the tumor cell and CD3 which "tells" the immune system to attack the tumor. ASP2138 is a potential new treatment for people with stomach cancer, gastroesophageal junction cancer, (cancer where the tube that carries food (esophagus) joins the stomach) or pancreatic cancer. Before ASP2138 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. This information will help to find a suitable dose and to check for potential medical problems from the treatment. Adults 18 years or older with stomach cancer, gastroesophageal junction cancer, or pancreatic cancer can take part. Their cancer is locally advanced unresectable or metastatic. Locally advanced means the cancer has spread to nearby tissue. Unresectable means the cancer cannot be removed by surgery. Metastatic means the cancer has spread to other parts of the body. The main aims of the study are to check the safety of ASP2138, how well it is tolerated, and to find a suitable dose of ASP2138 to be used later in this study. This is an open-label study. This means that people in this study and clinic staff will know that people will receive ASP2138. The study will have 2 phases. In phase 1, different small groups of people will receive lower to higher doses of ASP2138. Any medical problems will be recorded at each dose. This is done to find suitable doses of ASP2138 to use later in the study. The first group will receive the lowest dose of ASP2138. A medical expert panel will check the results from this group and decide if the next group can receive a higher dose of ASP2138. The panel will do this for each group until all groups have received ASP2138, or until suitable doses have been selected for later in the study. Doctors will also check how each type of cancer is responding to ASP2138. In phase 1b, other different small groups will receive suitable doses of ASP2138 found from phase 1. This phase will check how each type of cancer responds to ASP2138. The response to ASP2138 is measured using scans and blood tests. Doctors will continue to check all medical problems throughout the study. ASP2138 will be given through a vein in the arm. This is called an infusion. People will receive weekly infusions of ASP2138 in a 14-day (2-week) treatment cycle. People will continue to receive treatment until: their cancer gets worse; they have medical problems they can't tolerate; they ask to stop treatment; the doctors decide that continuing treatment is no longer in that person's best interest; the study is ended by the sponsor. Doctors will check if people had any medical problems from ASP2138. Other checks will include medical examinations, checking the nervous system, blood and urine tests and vital signs. Nervous system checks include checking peoples state of mind, reflexes, balance, movement and muscle strength. Vital signs include medical examinations, body temperature, breathing rate, and blood oxygen levels. Electrocardiograms (ECG) will be done to check the heart rhythm during the study. People will receive ASP2138 in a hospital. They will have blood tests and doctors will check for medical problems. People will also visit the clinic on certain days during their treatment, with extra visits during the first 3 cycles of treatment. People will visit the clinic after treatment has finished. The doctors will check for more medical problems. Other checks will include medical examinations, blood and urine tests, and vital signs. People will also have an ECG. After this, people will visit the clinic for a check-up several times. The number of visits and checks done at each visit will depend on the health of each person and whether they completed their treatment or not.

A Phase 2/3 Study of Evorpacept (ALX148) in Combination With Trastuzumab, Ramucirumab, and Paclitaxel in Patients With Advanced HER2-overexpressing gastric/GEJ adenocarcinoma.

RGX-202-01 (ompenaclid) is a Phase 1, first-in-human, dose escalation and expansion study of RGX-202-01 as a single agent and in combination with FOLFIRI +/- bevacizumab. RGX-202-01 is a small molecule inhibitor of the creatine transporter SLC6a8, a novel metabolic target that drives gastrointestinal cancer progression. During the dose escalation stage, multiple doses of orally administered RGX-202-01 with or without FOLFIRI +/- bevacizumab (single agent or combination therapy) will be evaluated in patients with advanced gastrointestinal tumors (i.e., locally advanced and unresectable, or metastatic) who have had PD on available standard systemic therapies or for which there are no standard systemic therapies of relevant clinical impact. In the expansion stage: Patients with colorectal cancer (CRC) RAS Mutant will be treated at the optimal dose.

The main objective of this study is to compare efficacy of bemarituzumab combined with oxaliplatin, leucovorin, and 5-fluorouracil (5-FU) (mFOLFOX6) to placebo plus mFOLFOX6 as assessed by overall survival (OS) in participants with FGFR2b ≥10% 2+/3+ tumor cell staining (FGFR2b ≥10% 2+/3+TC)

This phase I trial studies a new imaging technique called FAPi PET/CT to determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulate in normal and cancer tissues in patients with non-prostate cancer. The research team also want to know whether what they see on PET/CT images represents the tumor tissue being excised from the patient's body. The research team is also interested to investigate another new imaging technique called PSMA PET/CT. Participants will be invited to undergo another PET/CT scan, with the PSMA tracer (68Ga-PSMA-11). This is not required but just an option for volunteer patients. Patients who have not received an 18F-FDG PET/CT within one month of enrollment will also undergo an FDG PET/CT scan. The PET/CT scanner combines the PET and the CT scanners into a single device. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, in the case of this research, 68Ga-PSMA-11 and 68Ga-FAPi, and 18F-FDG (if applicable). Because some cancers take up 68Ga-PSMA-11 and/or 68Ga-FAPi it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs where it occurs in patient's body. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers. PSMA stands for Prostate Specific Membrane Antigen. This name is incorrect as PSMA is also found in many other cancers. The function of PSMA is not well understood but imaging studies have shown that PSMA can be detected with PET in many non-prostate cancers. Imaging FAP with PET/CT may in the future provide additional information about various cancers.
