Music festival anxiety study pulled before it began
NCT ID NCT05729503
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study planned to test whether a lidocaine nerve block (SPG block) could reduce anxiety in adults at electronic dance music festivals, compared to a saline placebo. The trial was withdrawn before enrolling any participants, so no data were collected. The approach was experimental and not proven.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lidocaine
- What this could lead to
- If it had worked, this could have pointed toward a quick, non-drug way to ease anxiety in stressful public settings.
- What could go wrong
- The trial was withdrawn before any participants were enrolled, so no results exist. Even if conducted, it was a small early-phase study with a placebo control, so any benefit would need much more testing.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Festival attendees aged 18+ * A complaint of anxiety of at least 1 on a scale of 0 to 10 (11-point scale, where 0 represents "no anxiety" and 10 represents "worst anxiety imaginable"). Exclusion Criteria: * Known allergy to lidocaine (standard practice involves medical team members asking patients what allergies they have; we will not directly ask about lidocaine in order to keep participants blinded to interventions) * Inability to insert cotton tip applicator through the nares (e.g., distorted nasal anatomy, active nosebleed, obstructed nasal passages) * Inability to verbally report level of anxiety * Prior administration of an oral or intravenous anti-anxiety medication (e.g., lorazepam, midazolam) by festival medical staff since arrival at the festival (would confound treatment effect)
