The standard treatment for advanced gastric cancer without metastases is gastrectomy, where the whole stomach or a large proportion is removed surgically together with regional lymph nodes. Some patients cannot tolerate this invasive procedure because of old age or comorbidities. A tumor left in place can cause local symptoms such as bleeding or outlet obstruction. In this study, the investigators want to test the safety and feasibility of Laparoscopic and Endoscopic Collaborative Surgery (LECS) as a less invasive treatment option to locally remove gastric tumors without requiring extensive surgery in these frail patients. LECS is a minimally invasive surgical technique where the tumor margin is first marked from the inside with a gastroscope, followed by surgical removal of the lesion under endoscopic guidance.

Despite declining incidence rates, gastric cancer (GC) ranks the fourth leading cause of cancer-related mortality and the fifth most common cancer worldwide, with the highest incidence reported in Eastern Asia. The 5-year overall survival rate of early GC exceeds 90%, which was well above advanced GC. Most intestinal-type GCs follow the Correa cascade-inflammation,atrophy, intestinal metaplasia (IM), dysplasia and subsequent carcinoma. The presence of gastric mucosal atrophy and intestinal metaplasia are important risk factors for GC. The purpose of this study was to investigate the incidence of GC attributed to atrophic gastritis in a region with high incidence of GC.

This study will help find the most suitable dose of ASP546C in people with gastric cancer, gastroesophageal junction (GEJ) cancer, pancreatic cancer, and other specific solid tumors. GEJ is where the food pipe (esophagus) joins the stomach.
This study is in 2 parts. In both parts of the study, ASP546C will be given once in 3-week cycles. It will be given slowly through a tube into a vein. This is called an infusion.
In Part 1, people with gastric cancer or GEJ cancer can take part. They will receive an infusion of either a higher dose or a lower dose of ASP546C.
In Part 2, people with pancreatic cancer or who have one of the other solid tumors can take part. Part 2 doesn't include people with gastric cancer or GEJ cancer. All people in this part of the study will receive an infusion of the higher dose of ASP546C.
People will visit the clinic on certain days to receive ASP546C and have health checks. The number of visits and checks done during the study will depend on the health of each person and whether they are still receiving infusions of ASP546C.

Zolbetuximab is being studied in people with cancer in and around the stomach or where the food pipe (esophagus) joins the stomach, called gastroesophageal junction (GEJ) cancer. Zolbetuximab with chemotherapy may be used to treat stomach and GEJ cancer when the cancer cells do not have a protein called HER2 (human epidermal growth factor receptor 2) on their surface (HER2-negative) but do have a protein called Claudin 18.2 (Claudin 18.2-positive). Zolbetuximab is thought to work by attaching to the Claudin 18.2 protein in their tumor, which switches on the body's immune system to attack the tumor. Certain stomach and GEJ cancers may be treated with immunotherapy, which helps the body's immune system fight cancer. This study will give more information about how well zolbetuximab works when given with an immunotherapy medicine called pembrolizumab and chemotherapy. In this study, adults with stomach cancer or GEJ cancer will either be given zolbetuximab with pembrolizumab and chemotherapy or a placebo with pembrolizumab and chemotherapy. A placebo looks like zolbetuximab but doesn't have any medicine in it.
The main aim of the study is to check how long people with stomach cancer and GEJ cancer live after treatment with zolbetuximab with pembrolizumab and chemotherapy compared to placebo with pembrolizumab and chemotherapy.
Adults with locally advanced unresectable or metastatic stomach cancer or GEJ cancer can take part. 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. A tumor sample (biopsy) of their cancer will have the Claudin 18.2 protein, PD-L1 protein, and be HER2-negative. They may have been previously treated with certain standard therapies. People can also take part if they need to take medicines like steroids to suppress their immune system. They cannot take part if they have blockages or bleeding in their gut, have specific uncontrollable cancers such as symptomatic or untreated cancers in the nervous system, or have a specific heart condition, or infections.
The study treatments are either zolbetuximab with pembrolizumab and chemotherapy, or placebo with pembrolizumab and chemotherapy. People who take part will receive just 1 of the study treatments by chance. The people in the study and the study doctors will not know who takes which of the study treatments. Study treatment will be given in 6-week (42-day) cycles. The study treatment is mainly given to people slowly through a tube into a vein. This is called an infusion. People will receive study treatment as follows: Zolbetuximab or placebo: 1 infusion every 2 or 3 weeks (2 or 3 infusions in a cycle) together with: Chemotherapy (1 of the following types of chemotherapy): 1. CAPOX (capecitabine and oxaliplatin): 1 infusion of oxaliplatin every 3 weeks (2 infusions in a cycle). People will also take 1 tablet of capecitabine twice a day for 2 weeks (14 days) at the start of each cycle (Day 1) and again in the middle of each cycle (Day 22). After 8 study treatments people will receive capecitabine only. 2. Modified FOLFOX6 or mFOLFOX6 (5-fluorouracil, folinic acid and oxaliplatin): 1 infusion every 2 weeks (3 infusions in a cycle). After 12 study treatments people will receive folinic acid and fluorouracil only, instead of mFOLFOX6. Pembrolizumab: 1 infusion every 3 or 6 weeks (1 or 2 infusions in a cycle). People can be in the study and will receive study treatment until their cancer worsens, they cannot tolerate the study treatment, or they need to start another cancer treatment. People may receive pembrolizumab for up to 2 years. People will visit the clinic on certain days to receive their study treatment and have health checks. The study doctors will check if people had any medical problems from taking zolbetuximab or the other study treatments. On some visits they will have scans to check for any changes in their cancer. People will have the option of giving a tumor sample if they stop treatment because their cancer has worsened. People will visit the clinic after they stop their study treatment. People will be asked about any medical problems and will have a health check. People will continue to have scans every 9 or 12 weeks to check for any changes in their cancer. They will have telephone health checks 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 study treatment or not.
