Impact of Vertigoheel® on Patients Suffering From Bilateral Vestibulopathy and Functional Dizziness

Completed

Conditions: Vertigo
Functional Dizziness
Bilateral Vestibulopathy

Registration Number: NCT05897853

Lead Sponsor: Ludwig-Maximilians - University of Munich

Brief Summary: In this study the researcher observe how vertigo symptoms change during two months of treatment with the natural medicinal product Vertigoheel©. Adult patients suffering from vertigo symptoms can participate if they are diagnosed with bilateral vestibulopathy (BVP) or functional dizziness (FD) and assigned to Vertigoheel treatment. Participating patients receive an examination at study start and after 2 months of Vertigoheel treatment. The study focuses on patient reported outcomes assessed by questionnaires.

Vertigo symptoms are assessed by the Dizziness Handicap Inventory questionnaire. Patients' quality of life is assessed by a questionnaire. Body sway is assessed by static posturography. FD patients are additionally tested for depressive and anxiety symptoms by questionnaires. BVP patients are additionally tested for vestibular function by video head impulse test and caloric testing. Adverse events and other observations related to safety (physical examination and vital signs) are evaluated.

Vertigo is a common symptom with significant adverse effects on patients' quality of life. Regardless of the exact cause of vertigo attacks, it is important to reduce the frequency, intensity, and duration of vertigo attacks with an effective medication that has no or minimal adverse effect. Vertigoheel®, a natural medicinal product consisting of four ponderable active ingredients, is approved in Germany as treatment for vertigo of various origins. However, no systematic data are available for Vertigoheel® regarding patient-reported outcomes in BVP and FD as the most accepted endpoint in vertigo studies.

Study & Design

Study Type: OBSERVATIONAL

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Dizziness Handicap Inventory	2 months	Change from baseline in dizziness handicap inventory (DHI) after 2±1 months Vertigoheel® treatment. The DHI, ranging from 0 to 100 with higher scores indicating greater severity, was assessed at two time points: baseline and 2 months.

Secondary Outcome Measures

Name	Time	Method
Quality of Life (QoL)	2 months	Change from baseline in quality of life (QoL) assessed by EQ-5D-5L after 2±1 months Vertigoheel® treatment. The EQ-5D index was used as described by Ludwig et al. (PharmacoEconomics, 2018, 36:663-74), ranging from -0.661 to 1.000, with higher scores indicating better quality of life. QoL was assessed at two time points: baseline and 2 months.
Postural Imbalance	2 months	Change from baseline in body sway assessed by static posturography after 2±1 months Vertigoheel® treatment. Posturography was assessed as described by Brandt et al. (J Neurol 2012, 259:182-4) with an artificial neural network analysis. Category three of the method for "peripheral vestibular deficit" was evaluated for patients with bilateral vestibulopathy, and category five for "phobic postural vertigo" was evaluated for patients with functional dizziness. Posturography was assessed at two time points: baseline and 2 months. Reported values indicate the deviation from baseline values. Positive values indicate more swaying and negative values indicate less swaying. The higher the value, the more swaying (worse regulation of stand). The 2-month values were examined for significant differences from baseline values. One-sample t-Tests were used to compare mean change from baseline values versus zero (no change).
Depressive Symptoms in Functional Dizziness	2 months	Change from baseline in depressive symptoms of functional dizziness patients assessed by PHQ-9 questionnaires after 2±1 months Vertigoheel® treatment. The PHQ-9, ranging from 0 to 27 with higher scores indicating greater severity, was assessed at two time points: baseline and 2 months.
Anxiety Symptoms in Functional Dizziness	2 months	Change from baseline in anxiety symptoms of functional dizziness patients assessed by GAD-7 questionnaires after 2±1 months Vertigoheel® treatment. The GAD-7, ranging from 0 to 21 with higher scores indicating greater severity, was assessed at two time points: baseline and 2 months.
