3 Clinical Trials for Various Conditions
Zolbetuximab is being studied as a treatment for people with cancer in and around the stomach or cancer where the food pipe (esophagus) joins the stomach (gastroesophageal junction cancer). Most people with this type of cancer have a protein called Claudin 18.2 in their tumor. Zolbetuximab is thought to work by attaching to Claudin 18.2 in their tumor. This switches on the body's immune system to attack the tumor. There is an unmet medical need to treat people with advanced cancer in and around the stomach or gastroesophageal junction cancer. This study will provide more information on zolbetuximab given by itself and in combination with other treatments in adults with advanced stomach or gastroesophageal junction cancer. The study is currently ongoing globally. People in this study will either be treated with zolbetuximab by itself, with zolbetuximab and chemotherapy, with zolbetuximab and a medicine called pembrolizumab, or zolbetuximab with chemotherapy and a medicine called nivolumab. This study is ongoing, but enrollment in any of the treatment options has been completed. In addition, at this stage of the study, treatment in some of these treatment options has completed. The main aim of this study is to check how well zolbetuximab controls tumors when given by itself. Adults with cancer in and around the stomach or gastroesophageal junction cancer can take part. Their cancer is locally advanced unresectable or metastatic and has the CLDN18.2 marker in a tumor sample. 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. They may have been previously treated with standard therapies. People cannot take part if they need to take medicines to suppress their immune system, have blockages or bleeding in their gut, have specific uncontrollable cancers such as symptomatic or untreated cancers in the nervous system, have a specific heart condition or infections. There are different treatments in the study. People who take part will receive just 1 of the treatments. Treatment will be given in cycles. The treatment is given through a vein; this is called an infusion. Some people with advanced disease will have 1 infusion in 3 week (21-day) cycles. Some people will have several infusions in 6 week (42-day) cycles. Some people with cancer in and around the stomach or gastroesophageal junction who have surgery for their cancer will have a few infusions in 2-week (14-day) cycles. This will happen before and after they have surgery for their cancer. People may receive chemotherapy for up to 6 months. Some people enrolled to received zolbetuximab and pembrolizumab, may have received pembrolizumab for up to 2 years. People will visit the clinic on certain days during their treatment; there may be extra visits during the first cycle of treatment. The study doctors will check if people had any medical problems from zolbetuximab and the other study treatments. Also, people in the study will have a health check including blood tests. On some visits they will also have scans to check for any changes in their cancer. Tumor samples will be taken at certain visits with the option of giving a tumor sample after treatment has finished. People will visit the clinic after they stop treatment. They will be asked about any medical problems and will have a health check including blood tests. After the clinic visits end some people will have a telephone health check every 3 months. 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.
This is a phase I study of the experimental anticancer drug oxaliplatin. It is designed to establish the maximum dose of the drug that can be given safely to patients with cancer who have impaired liver function and to determine the drug's side effects. It will also examine how liver function affects the drug's elimination from the body. The liver plays an important role in the elimination of many anticancer drugs, and patients with impaired liver function should not take certain drugs or should take them in reduced doses. Patients 18 years of age and older with cancer that has metastasized (spread from the original tumor site) and for whom standard treatment is not available or is no longer effective may be eligible for this study. Candidates will be screened with various tests and procedures that may include physical examination, computerized tomography (CT) or magnetic resonance imaging (MRI) scans, chest X-rays, and blood and urine tests. Participants will be given oxaliplatin in doses determined according to their level of liver function. Patients may have normal liver function or mildly, moderately or severely impaired liver function, or may have had a liver transplant. Oxaliplatin will be infused intravenously (through a vein) over two hours on the first day of 21-day treatment cycles-that is, once every 3 weeks. Treatment will continue as long as the cancer is under control and side effects do not require stopping the drug. Urine will be collected over 48 hours after the infusion to determine how much of the drug is eliminated in urine. Blood tests will be done to monitor safety of the treatment, and imaging studies, such as X-rays, CT and MRI scans, will be done periodically to evaluate the tumor's response to treatment. Special blood tests will also be done to study how oxaliplatin is eliminated from the body. With the first dose of the drug, blood samples will be collected just before the infusion begins, just before it ends, 15 minutes, 30 minutes, 1, 2, 4, 6, 24, 48, and 72 hours after the infusion, and again 1 week and 3 weeks later. Additional blood samples may be collected at the third treatment cycle.
Oxaliplatin is an experimental anti-cancer drug that can shrink tumors such as colon cancer. However, because this drug can damage the kidneys, it is necessary to determine what doses of the drug can safely be given to patients with poor kidney function. Patients with advanced cancer, poorly functioning kidneys, and no good standard treatment options are eligible for this study. Candidates will be screened with imaging tests, such as CT and MRI scans, to determine the size and location of the cancer and with blood and urine tests to evaluate kidney and liver function. Study participants will receive oxaliplatin intravenously (through a vein) every 3 weeks for as long as the cancer is under control and there are no serious side effects from the drug. If significant side effects develop, the dosage will be reduced, or the drug will be stopped. Blood tests to measure blood cell counts will be done at least once a week, and CT scans, chest X-rays, and MRIs will be done about once every 6 weeks to assess the tumor's response to the treatment. Additional blood tests will be done at the beginning of the first two treatment cycles to measure the amount of oxaliplatin in the blood, and urine will be collected during the first 24 hours of drug treatment to determine how much drug is eliminated by the body in urine.
