研究概览
简要总结
AUTOMATIC SUBDERMAL INJECTOR SYSTEM (ASIS) Corporation has developed and patented the only automatic injection system for delivery of injectable products to the optimum spot, just outside of the fascia, which exists subdermally (between the skin and muscle) or interfascial (between the deeper muscles). ASIS device creates that bloodless space, enhancing Enbrel's efficacy and preventing unnecessary distant spread and adverse reactions. This space remains bloodless as long as the skin is lifted up or filled with an injectable product. Although ASIS device was initially designed to best administer BOTOX for such muscular conditions as Upper limb Spasticity, Cervical Dystonia, Chronic Migraine, Strabismus, Blepharospasm, and Primary Axillary Hyperhidrosis, the technology will also benefit other injectable products, including: GAMMAGARD for Primary Immunodeficiency (PI) and Insulin for Diabetics, etc.
详细描述
Over 6 months, Aim 1 will demonstrate that ASIS device consistently delivers an injectable product (e.g. Gadolinium) into that subdermal bloodless space. MRI is the most simple and logical imaging choice, preferred because with ultrasound, air is injected, which will dissipate too quickly out of bloodless space to allow measurements. Since there isn't a way to measure the level of Gadolinium within that subdermal bloodless space, at least the Prolongation of Gadolinium may be approximated by its greater or longer Persistent % on MRI. Also, since we can't assume that bloodless space for patients with a particular disease will behave the same way as normal patients or patients with different diseases, this approximation only works if the variables are minimized to the same particular skin affected by Plaque Psoriasis. Case in point, patients with Plaque Psoriasis tend to have thicker skin, so expectantly will have prolonged Gadolinium subcutaneously Persistent %, which may be very different from the other diseases and certainly from the skin of normal patients, while the Gadolinium subdermally Persistent % should remain the same. Therefore, the Relative Prolongation Ability Score or total Persistent % subdermally over total Persistent % subcutaneously, will be different and very specific for the particular skin affected by Plaque Psoriasis. However, they are valuable indicators that will help us modify the Enbrel dosage and duration to inject into that "unknown" subdermal space for Aim 2, from the "known" typical Enbrel dosage and duration for Plaque Psoriasis patients. For example, if Aim 1 found the Relative Prolongation Ability Score for the Plaque Psoriasis skin to be (2.00), then the typical subcutaneously Enbrel 50mg every 3 days, should be 25mg every 6 days subdermally.
Over 12 months, Aim 2 will again demonstrate the advantages of ASIS device injecting subdermally versus subcutaneously, but using Enbrel instead of Gadolinium on the particular skin affected by Plaque Psoriasis. Once we have shown ASIS device's consistent performance in Aim 1, then we may assume will deliver another product (Enbrel) into that bloodless space without the need to measure Enbrel's existent in that bloodless space. Using Enbrel instead of Gadolinium, we'll demonstrate the advantages of injecting subdermally over intramuscularly for the same affected skin sites in the same 60 adult subjects.

结局指标
主要结局
Relative Prolongation Ability Score for Gadolinium subdermally injected.
时间窗: 6 months
Gadolinium will be injected with ASIS subdermally (30) or conventional subcutaneous (30) for 60 adult subjects with Plaque Psoriasis (involving at least 10% of body surface and a minimum Psoriasis Area \& Severity Index (PASI) score of 10), just for the particular plaque skin area. The first MRI taken promptly after Gadolinium injection for each patient would be his or her reference of 100% Persistent, to which his or her subsequent MRI taken @ 6 hr, @ 12 hr, and @24hr later will be compared for Persistent %.This approximation can only work if the variables are minimized to the same population with Plaque Psoriasis, and the particular plaque skin area. The Relative Prolongation Ability Score or total Persistent % subdermally over total Persistent % subcutaneously, Plaque Psoriasis will be very valuable indicators for us to modify the Enbrel dosage and duration for testing with that "unknown" subdermal bloodless space in Aim 2.
次要结局
