About this study
Official title: A Phase II Randomized Controlled Double-Blind Clinical Trial of Sphenopalatine Ganglion (SPG) Block for Headache After Concussion
This clinical trial will enroll participants to evaluate the effects of SPG block on post-traumatic headache. The study hypothesizes that patients that receive a SPG block with lidocaine vs. placebo (saline) will have a lower number of headache days in the week following the procedure, and will also report lower symptom scores.
Eligible participants will receive one treatment (SPG block) as well as complete surveys prior to and after receiving treatment (for a total of approximately 2 weeks).
- Conditions
- Concussion, Headache
- Being tested
- Lidocaine in SphenoCath device, Saline Solution in SphenoCath device
- Keywords

Measured: 48 hours pre SPG to 48 hours post block
Mean Headache Occurrences Within 1 Week Pre- and 1 Week Post-SPG Block
The number of headache episodes over the one week prior to the SPG block to one week after the procedure.
Measured: 1 week before SPG block up to 1 week post SPG block

Mean Number of Days With Headache in the1 Week Post-SPG Block Compared to 1 Week Pre-SPG Block.
Measured: 1 week before SPG block up to 1 week post SPG
Mean Change in As-needed Headache Treatment Uses
Patients will be asked to report the number of uses of as-needed headache medications used in the one week prior to the SPG block and after SPG block for up to one week after the procedure.
Measured: 1 week before SPG block to 1 week post SPG block
Mean As-needed Headache Treatment Uses Within 48 Hours Pre- and 48 Hours Post-SPG
Patients will be asked to report the number of uses of as-needed headache medications used in the one week prior to the SPG block and after SPG block for up to one week after the procedure.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Lidocaine in SphenoCath device and Saline Solution in SphenoCath device in people with Concussion and Headache, run by University of Michigan at 1 site in United States.
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 2 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 14 Sep 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 May 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Mean Change in Headache Severity Score (time frame: 48 hours pre-SPG to 48 hours after SPG 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 14 Sep 2022; AzTrials last refreshed its copy on 6 Nov 2026.
