    Measured: Day 1 - Day 28±1

  6. Time elapsed before the total DHI score decreased by 30% or more from baseline

    Measured: Day 1 - Day 28±1

  7. Change in digital rating scale (DRS) score from Visit 1 to Visits 2, 3, 4, 5

    The difference between the total DRS score (from minimum of 0 to maximum of 10 points; higher scores mean a worse outcome) on Visit 2-5 and Visit 1

    Measured: Visit 2 (day 7±1), Visit 3 (day 14±1), Visit 4 (day 21±1), Visit 5 (day 28±1)

  8. Ddigital rating scale (DRS) score on Visit 2, 3, 4, and 5

    DRS score (from minimum of 0 to maximum of 10 points; higher scores mean a worse outcome) on the Visit

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Buspirone in people with Vertigo and Autonomic Dysfunction, run by Valenta Pharm JSC at 8 sites in Russia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 48 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Frequency of response to therapy at Visit 5 (time frame: Visit 5 (day 28±1)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2022.
