This clinical trial is focused on studying the effects of a treatment for patients with colorectal cancer, specifically those with certain genetic changes known as mutations in the PI3K signaling pathway. The treatment being tested is Acetylsalicylic Acid (ASA), commonly known as aspirin, which will be given in a dose of 160 mg once daily. The study aims to find out if this treatment can help delay the return of cancer in these patients compared to a placebo.
Participants in the study will have colon or rectal cancer at stages II or III, with specific genetic changes in their tumors, such as PIK3CA, PIK3R1, or PTEN. The study will last for three years, during which time patients will take the medication or placebo orally. The main goal is to see if the treatment can improve the time it takes for the cancer to come back after surgery.
The trial is designed to be a randomized, double-blind, placebo-controlled study, meaning neither the patients nor the researchers will know who is receiving the actual medication or the placebo. This approach helps ensure that the results are reliable and unbiased. The study will help determine if ASA can be an effective additional treatment for patients with these specific types of genetic changes in their cancer.
