Semaglutide effectively reverses alectinib-induced excessive weight gain in ALK+ NSCLC patients, though discontinuation due to gallstone pancreatitis can lead to weight regain.

If you are on alectinib and gaining significant weight, semaglutide can help you lose it, but you must get a baseline gallbladder ultrasound first. If you develop abdominal pain, stop the drug immediately as it may cause pancreatitis, which will cause you to regain the weight you lost.
