Frequently asked questions about Nexium

What is Nexium used for in Erosive Esophagitis?

Nexium is used for the treatment of Erosive Esophagitis, a condition where stomach acid damages the esophagus. It is being studied in pediatric patients aged 1 to 11 years to evaluate endoscopic evidence of maintenance of healing. The drug is administered orally and is currently in Phase 3 clinical development.

What does Nexium target?

Nexium targets the gastric proton pump, specifically the H+/K+-ATPase enzyme in stomach parietal cells. By inhibiting this enzyme, Nexium reduces gastric acid secretion, which helps heal and maintain healing of erosive esophagitis. This mechanism is well-established for proton pump inhibitors in gastrointestinal disorders.

Who makes Nexium?

Nexium is developed by AstraZeneca PLC, a global biopharmaceutical company listed on the stock exchange under the ticker AZN. AstraZeneca is conducting clinical trials to evaluate Nexium's efficacy and safety in pediatric patients with erosive esophagitis, with the drug currently in Phase 3 development.

What phase is Nexium in?

Nexium is in Phase 3 clinical development for the treatment of Erosive Esophagitis. It is an investigational drug in this pediatric indication and has not yet received regulatory approval for this use. The ongoing Phase 3 trial is active but not recruiting participants, indicating advanced stages of clinical evaluation.

What clinical trials is Nexium in?

Nexium is being evaluated in a Phase 3 clinical trial with the identifier NCT05267613. This randomized, double-blind, active-controlled study assesses endoscopic evidence of maintenance of healing with oral Nexium in patients aged 1 to 11 years with erosive esophagitis. The trial enrolls 53 participants across multiple countries including the United States, Argentina, Australia, and several European nations.

Is Nexium the same as Nexium 20mg?

Yes, Nexium 20mg is a specific dosage form of Nexium. The drug is also known as Nexium 20mg, which refers to the 20 milligram strength of the medication. Both names refer to the same active ingredient, esomeprazole, which is being studied in the Phase 3 trial for erosive esophagitis in pediatric patients.
