Low frequency brain stimulation for diarrhea-predominant IBS pain
This trial tests if a type of brain stimulation called low-frequency repetitive transcranial magnetic stimulation (lf-rTMS) can reduce belly pain in people with irritable bowel syndrome that causes diarrhea (IBS-D). It is a non-invasive treatment that uses magnetic pulses to target areas of the brain involved in pain perception.

Study of three drugs for advanced colorectal cancer after first treatment
This trial tests a combination of three drugs (irinotecan liposomes, cetuximab, and vemurafenib) for people with advanced colorectal cancer that has a specific genetic change (BRAF V600E mutation) and did not respond to first treatment. The goal is to see if this combination can help shrink tumors or slow the cancer's growth.
