Sensory Evaluation of Dexlansoprazole Delayed-Release Orally Disintegrating Tablets

The purpose of this study is to measure the in-vivo disintegration time of a single dexlansoprazole delayed-release orally disintegrating (OD) tablet.

The drug being tested in this study is called dexlansoprazole. An orally disintegrating (OD) form of dexlansoprazole is being tested to look at the average time that it takes for one tablet to disintegrate in the mouth of healthy volunteers. At the point at which the panelist would normally swallow the granules, they will record the time and expectorate the disintegrated tablet mass and not actually swallow the tablet or granules.

The study will enroll approximately 8 healthy volunteers. All participants will take one dexlansoprazole 30 mg OD tablet on up to three separate study days. No more than 60 mg of dexlansoprazole will be tested in any one day.

This single-centre trial will be conducted in the United States. The overall time to participate in this study is approximately 2 weeks. Participants will make up to 4 visits to the clinic, and will be contacted by telephone approximately 1 week after last dose of study drug for a follow-up assessment.

Eligibility Criteria:
Inclusion Criteria:

1. The male or female sensory panelist is between 25 and 80 years of age (inclusive), healthy volunteers for study participation, and is able to read, understand, and sign and date a written informed consent form (ICF) and any required privacy authorization before study participation.
2. In the opinion of the investigator, the participant is capable of understanding and complying with protocol requirements.
3. The sensory panelist is qualified based on documented training and experience: All panelists will be provided by Senopsys, LLC: Panelists have been trained to detect, identify, recognize, and accurately describe different taste elements and flavor combinations and to measure oral disintegration times. Training is initially accomplished by tasting model compounds and learning to recognize and describe these accurately. These abilities are then honed and refined through additional experience in performing product testing.

Exclusion Criteria:

1. Has a history of any illness that, in the opinion of the investigator or the sensory panelist's general practitioner, might confound the results of the study or pose an additional risk in administering study drug(s) to the sensory panelist. This may include but is not limited to: a history of relevant drug or food allergies; history of cardiovascular or central nervous system disease; history or presence of clinically significant pathology; recent history of disease involving head, neck, esophagus (especially malignancy, radiation therapy, fungal infection where taste perception can be altered) or history of mental disease.
2. If female, the sensory panelist is pregnant, nursing, planning to become pregnant during the study.
3. Has a known hypersensitivity to dexlansoprazole or any component of dexlansoprazole delayed-release orally disintegrating (OD) tablet or proton pump inhibitor (PPI) (including lansoprazole, omeprazole, rabeprazole, pantoprazole, or esomeprazole).
4. Is currently taking any contraindicated medications.
