A New Oral salIvary equivAlent Compared to Two moisturizinG Mouth sprAys in Patients With xeRostomiA: NIAGARA Study (NIAGARA)

January 27, 2014 updated by: Unither Pharmaceuticals, France

Phase 4 Study Evaluating Efficacy, Safety and Acceptability of Treatment With a New Salivary Equivalent Compared to Two Moisturizing Mouth Sprays on the Improvement of Dry Mouth Symptoms and Oral Comfort in Patients With Xerostomia.

The purpose of this study is to evaluate the clinical efficacy, safety and acceptability of our new oral salivary equivalent in the relief of signs and symptoms related to mouth dryness as compared to two distinct moisturizing currently marketed oral sprays (Aequasyal® & Biotene®) in patients with xerostomia due to chronic hyposalivation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Dry mouth discomfort
Time Frame: 14 days
Patient evaluation through the completion of a self rated 100 mm long VAS score. Anchor points of the VAS score will be 0 representing the absence of any dry mouth symptoms and 100 representing the worst imaginable picture of dry mouth discomfort
14 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
