About this study

Official title: The Effect of Ganglion Sphenopalatine Block (SPG-block) Versus Placebo on Persistent Headache Following COVID-19 Infection: a Randomised, Blinded, Clinical Trial

The purpose of this study is to evaluate the effect of the ganglion sphenopalatine block (SPG block) on persistent headache following acute COVID-19 infection.

Read the detailed description

Adult patients with persistent headache following COVID-19 infection will be enrolled in the study. The patients will be randomised into three groups; bilateral SPG-block withto receive local anesthetic (lidocaine + ropivacaine), bilateral SPG-block with placebo (isotone NaCl) or bilateral "sham"-block with placebo (isotone NaCl).

Primary outcome is hyperactivity in the sphenopalatine ganglion assessed by pain intensity (0-100mm on a visual analogue scale, VAS) of the headache in standing position 30 minutes after block in the group Ropicavain-Lidocain and "sham".

Being tested
Sphenopalatine Ganglion Block with Local Anesthetic, Sphenopalatine Ganglion Block with Placebo (Isotone NaCl), "Sham"-block with Placebo (Isotone NaCl)
Medical subject headings
Headache, COVID-19

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sphenopalatine Ganglion Block with Local AnestheticProcedure or surgery

    Block performed with bilaterally inserted q-tips with 1:1 mixture of lidocaine 40mg/ml and ropivacaine 5mg/mL

  • Sphenopalatine Ganglion Block with Placebo (Isotone NaCl)Procedure or surgery

    Block performed with bilaterally inserted q-tips with isotone NaCl

  • "Sham"-block with Placebo (Isotone NaCl)Procedure or surgery

    Block performed with bilaterally inserted q-tips with isotone NaCl. The q-tips are inserted a maximum of 3 cm into the nasopharynx thus not reaching the mucus above the ganglion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Hyperactivity in the sphenopalatine ganglion assessed by pain intensity (0-100mm on a visual analogue scale, VAS) of the postdural headache in standing position in the group Ropivacine-Lidocaine and "sham".

    Pain intensity will be measured as worst experienced pain after the patient has been standing for 30 seconds or the worst experienced pain while attempting to stand if the rating has to be interrupted.

    Measured: 30 minutes after block

Secondary outcomes (5)
  1. Number of patients with pain rating below 30mm in standing position (0-100mm on a visual analogue scale, VAS)

    Pain intensity measured as worst experienced pain after the patient has been standing for 30 seconds or the worst experienced pain while attempting to stand if the rating has to be interrupted.

    Measured: 30 minutes and 1 week after block

  2. Worst experienced pain in standing position (0-10 on a numercial rating scale, NRS)

    The worst experienced pain reported during the week following the block as registered by the patient.

    Measured: During study period until completion of 1 week follow up

  3. Average pain intensity (0-10 on a numercial rating scale, NRS)

    The average pain intensity reported during the week following the block as registered by the patient.

    Measured: During study period until completion of 1 week follow up

  4. Number of patients needing "rescue GSP-block"

    If the patient at the 1 week follow up still needs further treatment a "rescue SPG-block" defined as a new SPG-block with "open label" analgetics will be offered.

    Measured: At 1 week follow up

  5. Hyperactivity in the sphenopalatine ganglion assessed by pain intensity (0-100mm on a visual analogue scale, VAS) of the postdural headache in standing position in all 3 groups.

    Pain intensity will be measured as worst experienced pain after the patient has been standing for 30 seconds or the worst experienced pain while attempting to stand if the rating has to be interrupted.

    Measured: 30 minutes after block

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Sphenopalatine Ganglion Block with Local Anesthetic in people with Headache and Covid19, run by University Hospital Bispebjerg and Frederiksberg at 1 site in Denmark.

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 4 inclusion and 6 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: stopped early, as of the sponsor's last update on 10 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 1 site in Denmark. 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 was stopped early (reason given: Recruitment failure). Results are not available in the source record.

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?

Hyperactivity in the sphenopalatine ganglion assessed by pain intensity (0-100mm on a visual analogue scale, VAS) of the postdural headache in standing position in the group Ropivacine-Lidocaine and "sham". (time frame: 30 minutes after block). 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 10 Jun 2022.
