About

The study is designed to assess the effect and safety of oral administration of VECAM 40/300 administered at bedtime compared to Esomeprazole 20 mg administered 30-60 minutes before dinner, for control of nighttime and daytime HB and other 24 hour GERD symptoms.

The rational for the study is based on the contention that VECAM exhibits potent inhibition of acid secretion and because of its mechanism of action, it can be administered at bedtime without food. Such timing of drug dosing will allow effective inhibition of nighttime acid secretion. Because of its mechanism of action, VECAM exhibits improved 24-hour inhibition of acid secretion and hence, its bedtime administration will not compromise its effect during the daytime. This improved control of acid secretion will predictably result in better control of nighttime as well as daytime heartburn (HB) symptoms.

At least 28 days of PPI use prior to study entry
Patients have to be current PPI users with either:

- Category 2): only obtaining complete relief of GERD symptoms following the addition of acid suppressive agents (e.g. H2RA, additional PPI dose), or antacid therapy, to the approved PPI dose.
Reporting of ≥ 3 HB episodes in 7 consecutive days, at least two during the nighttime, w/o medical treatment during a screening period of up to 21 days (report is based on a daily diary during the screening period) and for Category 1 patients, at least one more HB episode as compared to single dose treatment period.
