ASIS for Enbrel in Plaque Psoriasis (ASISinPP)

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.

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Relative Prolongation Ability Score for Gadolinium subdermally injected.	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.	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Efficacy of Enbrel subcutaneously vs. subdermally in Plaque Psoriasis.	Hypothetically, if that subdermal bloodless space in patients somehow failed to show prolongation of half-life for Gadolinium in Aim 1, we can still proceed with Aim 2, because Enbrel's Pharmacokinetics will be studied anyway, by following tumor necrosis factor, then comparing the Mean tumor necrosis factor receptor : Fc. However, the Pharmacokinetics of subdermally injected Enbrel will be just dependent on Enbrel's diffusion out of that subdermal bloodless space. Therefore, if Enbrel getting into the bloodstream becomes so severely inhibited, then we can just change the osmolality of Enbrel in the end. Response to treatment will be assessed after 3, 6 and 9 months of therapy, and defined as the patients who achieved a reduction in score of at least 75% from baseline by the PASI.8 Other therapeutic advantages of ASIS device subdermally over subcutaneously will also be studied by comparing the reduction of adverse reactions and injection site pain.	12 months

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adverse Reactions of Enbrel subcutaneously vs. subdermally in Plaque Psoriasis	Adverse Reactions of Enbrel subcutaneously vs. subdermally: Heart failure, Allergic Reactions, Blood problems/low blood counts, Nervous system problems, such as multiple sclerosis, seizures, or inflammation of the nerves of the eyes, Infections (upper respiratory infection, pyelonephritis, bronchitis, septic osteomyelitis, wound infection, pneumonia, foot abscess, leg ulcer), Malignancies (lymphoma, basal & squamous skin cancer, non-cutaneous solid tumor, & Wegener's granulomatosis), Immunogenicity, Autoantibodies, Lupus-like syndrome, autoimmune hepatitis, and Injection site pain.	12 months
