The Next Leap Forward

Blockbuster Proton Pump Inhibitors (PPIs) such as Losec and Nexium have not been able to provide all gastroesophageal reflux disease (GERD) patients with sufficient disease control. Time has now come for Potassium-Competitive Acid Blockers (P-CABs) to take the next leap forward in the treatment of acid related diseases. Cinclus Pharma’s clinical stage drug candidate linaprazan glurate, formerly known as X842, takes a new approach to provide improved management of GERD.

Reflux diseases


Most people can relate to discomfort caused by reflux and heartburn, two of the most common symptoms caused by GERD. Symptoms often occur during or after eating and drinking, which affects both motivation and the ability to enjoy social activities such as picnics, dinners, events or just a cup of coffee with friends. More severe stages of GERD can be very painful, with difficulty in swallowing and esophageal erosions or ulcerations (esophagitis).
