Could a common gut drug keep colorectal cancer at bay?

This study tests whether adding lubiprostone, a drug used for constipation, to standard maintenance therapy can delay cancer recurrence in people with colorectal cancer that has spread to the lining of the abdomen. About 124 adults who have had surgery to remove visible cancer will be randomly assigned to receive lubiprostone plus standard care or standard care alone. The goal is to see if the combination improves the chance of staying cancer-free for at least one year.
