Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years - 65 Years|
- - If subjects takes occasional Aspirin (not taken daily), it will need to be withheld for seven days prior to Visit 2.
- - If subjects takes oral antihistamines, it will need to be withheld for seven days prior to the subject's first appointment - If subjects takes topical medications including (but not restricted to), cyclosporine, Elidel, Protopic, topical corticosteroids and topical antibiotics, it will need to withheld seven days prior to the subject's first appointment.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Visit 1 (if needed). Study subjects will be asked to read and sign the informed consent. At that time the study inclusion and exclusion criteria for the study will be reviewed. Subject will be given instructions to stop taking certain medications for 7 days prior to the next study visit. Alternatively, if Visit 1 will be done over the phone, subjects may be contacted via phone using a phone script to provide instructions for stopping these medications. In this case, the informed consent will be obtained by the subject at visit 2 prior to any study procedures being done. If the subject takes occasional Aspirin (not taken daily), it will need to be withheld for seven days prior to visit 2. If the subject takes oral antihistamines, it will need to be withheld for seven days prior to the subject's first appointment. If the subject takes oral antibiotics, inform the subject the appointment can be scheduled seven days after their last dose of antibiotic has been taken. If the subject takes topical medications including (but not restricted to), cyclosporine, Elidel, Protopic, topical corticosteroids and topical antibiotics, it will need to be withheld seven days prior to the subject's first appointment. If the subject takes any of the following medications, they are not eligible for enrollment: Oral corticosteroids Any systemic immunosuppressive or immunomodulary medication in the last 28 days. Patients who have received immunotherapy in the past year. Patients using anxiolytics or antidepressants Antiviral therapies Anticoagulants Allergic to lidocaine Daily Aspirin Visit 2: Will occur approximately 7 days following the screening visit or the phone call. If the subject was contacted via phone, he/she will be review and sign the informed consent form during this visit. The following procedures will be performed. Urine Pregnancy Test: All female can be pregnant or become pregnant during the study. The urine pregnancy test will be administered to all women of child bearing potential. If the test will be positive, the participation in the study will be terminated. Skin Biopsies: The skin biopsies will involve taking a small piece of skin (4 biopsies 2mm in diameter) generally obtained from the arms or legs, the face is excluded from skin biopsy. The area will be cleaned and numbed with a local anesthetic. Biopsies will be collected from non-lesion skin and acute lesions. The wound will not require a stitch and should be healed within two weeks. The biopsy site needs to be kept sterile and this will require that the area not get wet. The skin biopsies will be performed by one of the physician investigators or nurse practitioners. The subject will be given the name and phone number of a nurse and told to call if there are any problems. The subject will be given instructions on how to care for the biopsy site. Venipuncture: 7.5 mL of blood will be removed by putting a needle into a vein. The procedure will be performed by a physician investigator or a nurse in the CTRC. The subject will be given the name and phone number of a nurse and told to call if there are any problems. There will not be any follow-up for venipuncture procedures. DNA testing: Additional 7.5 ml of blood will be obtained for genetic testing of filaggrin gene polymorphisms (performed by ADx lab at NJH). Skin cultures: Skin is rubbed with a cotton swab then cells are placed in a special culture medium tube for identification of bacteria wabs will be tested for presence of S. aureus by culture and PCR. Tape Stripping. Adhesive skin sampling discs will be firmly pressed against the skin in a hairless location (not the face) followed by lifting it free of the skin. Skin tapes will be collected from non-lesion skin and acute skin lesions. This will be repeated up to 40 times. These discs will then be used to evaluate RNA, lipids and proteins in the upper layers of skin. With every 5 tape strips collected from one lesion and one non-lesion area skin barrier assessment will be preformed. Skin Barrier Assessment. Skin serves as the first barrier against allergens, viruses, and bacteria that may aggravate your skin disease. A small device will be used to measure the quantity of water that passes from inside the body through the skin to the surrounding atmosphere via diffusion and evaporation process. Additionally, the device will measure skin pH, which is also associated with changes in the skin barrier. Sweat Test. We will measure chemicals in patients' sweat, such as salt, which is known as a sweat test. To collect the sweat, a sticky pad will be attached to the skin on patients' arm for 5 minutes. A gel containing a medicine called pilocarpine is put on the pads and causes the sweat glands to produce more sweat. The pads are then removed and replaced by a disc to collect sweat for about 30 minutes. Sebum Collection. Skin surface will be cleaned with alcohol wipes. After allowing skin surface to dry sebum collecting tape will be applied to the skin surface. The tape will be held on the skin surface for one hour. The tape will then be used to evaluate skin sebum production. Optional Visits: The research team may ask the subject to return every 6 weeks and participate in additional skin biopsies, tape strips and blood draws (not to exceed 6.5 tablespoons (100 ml)). The subject may choose to participate in some or all optional visits not to exceed 6 additional blood draws, tape strips and/or biopsies in one year.
