Summary

This trial aims to assess the effect of combining Tadalafil with chemotherapy before surgery to remove tumors in patients with gastric/gastroesophageal junction adenocarcinoma. Tumor tissue, blood, urine & saliva will be collected.

Who is the study for?
Adults with resectable gastric or gastroesophageal junction adenocarcinoma, who haven't had prior treatments for their cancer. They must have a certain level of albumin in the blood, measurable disease by scans, and adequate organ function. Participants should not be pregnant or breastfeeding and must agree to use contraception during the study and for six months after.
What is being tested?
The trial is testing Tadalafil's effect on immune cells in the tumor environment when given alone and alongside standard chemotherapy (FLOT) before surgery. Patients will take Tadalafil for two weeks then combine it with FLOT for eight weeks, aiming to reduce suppressor cells that can hinder anti-cancer responses.
What are the potential side effects?
Tadalafil may cause headaches, indigestion, back pain, muscle aches, flushing, stuffy or runny nose. The combination with chemotherapy could add side effects like nausea, fatigue, low blood counts leading to increased infection risk or bleeding problems.
