Randomized, 3-arm Controlled Clinical Trial, Designed to Evaluate the Effectiveness of Supplementation With Vertistop® D and Vertistop® L in Preventing Recurrence of High-recurrence BPPV (Benign Paroxysmal Positional Vertigo)

Randomized, 3-arm controlled clinical study, to evaluate the effectiveness of supplementation with Vertistop® D (food supplement containing alpha-lipoic acid at modified release, Carnosine and Zinc, Vitamin D and Vitamins B) and Vertistop® L (food supplement containing fast releasing alpha-lipoic acid, Carnosine, Zinc and Curcumin) in preventing recurrence of high-recurrence BPPV (Benign Paroxysmal Positional Vertigo)

Intervention / Treatment

Detailed Description

Benign paroxysmal positional vertigo (BPPV) is the most common type of vertigo detectable in otoneurological clinical practice. It is characterized by violent, short and relapsing vertiginous crises that arise when the patient assumes certain positions of the head in the space and is accompanied by a usually "typical" paroxysmal positional nystagmus. In most cases we cannot trace the exact causal agent, so we mainly identify two forms: primitive forms and secondary forms. BPPV therapy is essentially physical, and it is based on specific maneuvers which make the otoconial mass come out of the semicircular canal. Recent studies showed the existence of a seasonal trend of BPPV related to fluctuations in Vitamin D levels. Based on these considerations this clinical trial was designed in order to evaluate the possible efficacy of the administration of Vitamin D (Vertistop® D) in preventing recurrence of BPPV.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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 to 81 years (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.

Measure Description
Time Frame

Time Frame: 0, 6 months
Change in the number of BPPV recurrences associated with the increase or normalization of Vitamin D serum levels after supplementation with Vertistop D
0, 6 months

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.
Outcome Measure
Measure Description
Time Frame
Number of BPPV recurrences in patients supplemented with Vertistop-L
Time Frame: 0, 6 months
This parameter is defined as the difference in the number of BPPV recurrences observed in the period between the baseline visit and the final visit (after 6 months)
0, 6 months
Mean difference in Dizziness Handicap Inventory (DHI) values
Time Frame: 0, 6 months
This parameter is defined as the mean difference in the DHI values between the baseline visit and the final visit (after 6 months)
0, 6 months
Mean difference in the Visual Numeric Scale (VNS) values
Time Frame: 0, 6 months

0, 6 months
Mean difference in the Visual Analogue Scale (VAS) values

0, 6 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
