Relative Prolongation Ability Score for Gadolinium subdermally injected.

研究概览

简要总结

Botox acts on nerve endings, yet there are no nerve endings inside the muscle, where they are typically injected. All nerves terminate on the fascia, where ASIS device can precisely deliver Botox by creating that subdermal bloodless space, between the skin and muscle. Thus enhancing and prolonging Botox's efficacy, at the same time prevent it's unnecessary adverse reactions and distant spread, especially since Botox has no reason to travel to the rest of the body any way.

详细描述

Aim 1 over 6 months will demonstrate ASIS device's consistent performance on 60 adult subjects with Chronic Migraine (≥15 days per month, with headache lasting 4 hours a day or longer). Gadolinium will be injected with ASIS subdermally (30) or conventional intramuscularly (30) for these 6 muscle groups: Glabella, Frontal, Temporal, Occipital, Paraspinal, and Trapezius. An MRI will be taken promptly after Gadolinium injection, as starting reference, to which subsequent MRI taken at 6 hrs, 12 hrs, and 24 hrs later will be compared for Persistent %. Since there isn't a way to measure level of Gadolinium within it, or any other (e.g. Botox) for that matter, at least the Prolongation of Gadolinium may be approximated by the greater or longer Persistent % on MRI. However, this approximation can only work if the variables are minimized to the same population with Chronic Migraine, and these particular 6 muscle groups. Case in point, patients with Chronic Migraine presumably have hyperactive Glabella, Frontal, Temporal, Occipital, Paraspinal, and Trapezius muscles, so expectantly will have shortened Gadolinium intramuscularly Persistent %, and somewhat Gadolinium subdermally Persistent % as well due to agitation, thus these Persistent % values in Chronic Migraine patients will not be like those of normal patients, or even the same between these 6 different muscle groups. Therefore, the Relative Prolongation Ability Score or total Persistent % subdermally over total Persistent % intramuscularly, will be specific and valuable indicators to help us modify the Botox dosage and duration to inject into that "unknown" subdermal bloodless space for Aim 2.

Aim 2 over 12 months, using Botox, instead of Gadolinium, to demonstrate the advantages of ASIS device subdermally over intramuscularly, for the particular 6 muscle groups on the same 60 Chronic Migraine adults. Given that there isn't a way to detect Botox in the peripheral blood to document Prolongation of Botox Pharmacokinetically, this Relative Prolongation Ability is our best and only possible way to demonstrate that subdermal bloodless space's ability on Botox. Although valuable, that Relative Prolongation Ability Score from Aim 1 isn't absolutely required to start Aim 2. Hypothetically speaking, if that subdermal bloodless space in patients with e.g., Chronic Migraine somehow failed to show prolongation of half-life for Gadolinium in Aim 1, we can still proceed with primary interest being therapeutic comparison for Botox in Aim 2, in terms of reduction in Number of Headache Days from Baseline, and adverse reactions.

结局指标

主要结局

Relative Prolongation Ability Score for Gadolinium subdermally injected.

时间窗: 12 months

Gadolinium will be injected with ASIS subdermally (30) or conventional intramuscularly (30) in Chronic Migraine adult patients for these 6 muscle groups: Glabella, Frontal, Temporal, Occipital, Paraspinal, and Trapezius. An MRI will be taken promptly after Gadolinium injection, as starting reference, to which subsequent MRI taken at 6 hrs, 12 hrs, and 24 hrs later will be compared for Persistent %. This approximation can only work if the variables are minimized to the same population with Chronic Migraine, and these particular 6 muscle groups. The Relative Prolongation Ability Score or total Persistent % subdermally over total Persistent % intramuscularly, in Chronic Migraine patients will not be like those of normal patients, or even the same between these 6 different muscle groups, but valuable indicators to help us modify Botox dosage and duration to inject into "unknown" subdermal bloodless space for Aim 2.
