Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Sclerotherapy Intervention | This group will receive, on the first period of the study, sclerotherapy with STS to any visible lesions in the nose at the outset, followed by any needed standard treatments for breakthrough epistaxis. On the second period of the study this group will continue with standard treatments that they had been receiving for epistaxis prior to the study. Standard treatment may include nasal packing, cauterization, laser treatments, microdebrider, and septodermoplasty.~Individual injection amounts vary between lesions, patients and treatment sessions. No more than 3 ml of solution is used in each session. | 0 | 18 | EG000 |
| Group 2 | Standard Treatment | The standard treatment group will continue their pre-study standard treatment methods to treat epistaxis on the first period of the study, followed by intervention with sclerotherapy on the second period of the study, plus any additionally needed standard treatments for breakthrough epistaxis. Standard treatment may include nasal packing, cauterization, laser treatments, microdebrider, septodermoplasty, and any other treatments that the patient reports using that are accepted as standard of care.~Sodium tetradecyl sulfate (STS) is injected into the nasal lesions as a solution prepared by foaming STS with air at a 4:1 ratio. Individual injection amounts vary between lesions, patients and treatment sessions. No more than a total of 3 ml of solution is used in each session. Multiple lesions can be treated bilaterally, each with a separate injection.~Standard Treatment | 0 | 18 | EG001 |
