What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in pain scale using Numeric rating scale
Pain assessment by using a Numeric rating scale (0 (no pain) to 10 (worst possible pain). Scores of 1-3 are considered mild, 4-6 moderate, and 7-10 severe) before the infusion and daily for 1-week post infusion, then weekly for 6 weeks post infusion
Measured: From enrollment to the end of treatment at 6 weeks
Changes in pain scale using Migraine disability assessment
Migraine disability assessment test before the infusion and daily for 1-week post infusion, then weekly for 6 weeks post infusion
Measured: From enrollment to the end of treatment at 6 weeks

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Ketamine infusion, Lidocaine Intravenous Infusion and Dextrose 5% in water in people with Refractory Chronic Migraine, run by Assiut University.
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 6 inclusion and 4 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: opening soon, as of the sponsor's last update on 20 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.
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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact AbdElRahman Mohamed Mohamed (+201066586931, hmdmhmmdl1692@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes in pain scale using Numeric rating scale (time frame: From enrollment to the end of treatment at 6 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06935552, which also lists 5 linked publications.
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 20 Apr 2025; AzTrials last refreshed its copy on 7 Nov 2026.
