Provide written informed consent before initiation of any study procedures.
Available for follow-up for the planned duration of the study.
Able to communicate well with the investigators.
Demonstrate comprehension of the protocol procedures and knowledge of study, as demonstrated by a study member filling out a consent checklist form to verify that the subject understands all aspects of the study including the purpose, procedures, risks and benefits.
Able to adhere to the study protocol schedule, study restrictions and examination schedule.
Subjects must be non-smokers and not regular users of tobacco. They must have refrained from regular and habitual use of nicotine-containing substances, including tobacco products (e.g., cigarettes, cigars, chewing tobacco, gum, patch or electronic cigarettes) over the previous 12 months and must have not used any nicotine-containing products in the previous 30 days.
Subjects who are within their ideal body weight (BMI between 18-29.9 kg/m2).
Subjects deemed to be healthy as judged by the Medically Accountable Investigator (MAI), as determined by medical history, physical examination, and medication history.
Negative urine drug screening test.
Have a normal blood pressure (systolic: 90-139 mmHg; diastolic: 60-89 mmHg) and heart rate (55-100 bpm).
Have normal screening laboratories for WBC, Hgb, Hct, platelets, sodium, potassium, chloride, bicarbonate, BUN, creatinine, ALT, AST.
Female subjects must be of non-childbearing potential. This is defined as surgically sterile (i.e. history of hysterectomy or tubal ligation), or postmenopausal for more than 1 year (no bleeding for 12 consecutive months). If the person is of childbearing potential they must be non-pregnant at the time of enrollment and on the morning of the first day of each study treatment procedure day (a urine pregnancy test will be administered if it has been >30 days since serum pregnancy test for enrollment). The person must also agree to use hormonal or barrier birth control such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence, or a vasectomized partner.
Agrees not to participate in another clinical study during the study period unless the study is in the follow-up phase and it has been one month since the subject received any experimental agents or treatments. The subject also agrees not to participate in an investigational drug study for at least 30 days after last procedure day.
Agrees not to donate blood to a blood bank throughout participation in the study and for at least 60 days after last procedure day.
Have a normal ECG; must not have any of the following: pathologic Q wave abnormalities, significant ST-T wave changes, left ventricular hypertrophy, right bundle branch block, left bundle branch block, advanced A-V heart block, non-sinus rhythm, excluding isolated premature atrial contractions (sinus rhythm is not between 55-100 beats per minute), or any other abnormality that, in the opinion of the MAI, makes it unsafe for the subject to participate in the study.

Exclusion Criteria:

Women who are pregnant or lactating or have a positive serum pregnancy test at enrollment or positive urine pregnancy test at any time during the study.
Smokers. A "smoker", for the purposes of the study, will be defined as an individual who has regularly and habitually used nicotine-containing substances, including tobacco products (e.g., cigarettes, cigars, chewing tobacco, gum, patch or electronic cigarettes) over the past 12 months. Occasional recreational use (less than once monthly) will not warrant exclusion unless the individual has used nicotine-containing substances in the previous 30 days before study enrollment.
Participation in any ongoing investigational drug trial or clinical drug trial period unless the study is in the follow-up phase and it has been ≥ one month since the subject received any experimental agents or treatments.

Abnormal vital signs, defined as:

Hypertension (systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg) at rest on two separate days.
Heart rate <55 at rest on two separate days
Respiratory rate ≤ 11 to ≥ 18 breaths per minute
Temperature >38.0ºC (100.4ºF) or symptoms of an acute self-limited illness such as an upper respiratory infection or gastroenteritis within seven days of administration of a study product.
History of chronic obstructive pulmonary disease.
Positive urine drug screening test.
Use of any prescription medication during the period 0 to 30 days or over-the counter medication during the period 0 to 3 days before entry to the study (vitamins, herbal supplements and birth control medications will be allowed).
Use of medications or treatments that would significantly influence or exaggerate responses to the test product or that would alter inflammatory or immune response to the product. This includes antihistamines (within 72 hours prior to dosing), systemic or topical corticosteroids within four weeks prior to dosing, use of monoamine oxidase inhibitors 21 days prior to study, cyclosporine, tacrolimus, cytotoxic drugs, immune globulin, Bacillus Calmette-Guerin [BCG], monoclonal antibodies, or radiation therapy.
Donation or loss of greater than one pint of blood within 60 days of entry to the study.
Any prior serious adverse reaction or hypersensitivity to lidocaine administered by any route.
Current diagnosis of any major psychiatric illness.
Received an experimental agent (vaccine, drug, biologic, device, blood product or medication) within 30 days before enrollment in this study or expects to receive an experimental agent during the study.
Medical history of a serious chronic condition, including (but not limited to): allergic conditions such as anaphylaxis to food or drugs; asthma; generalized drug reactions; any seizure disorder; any central nervous system disorder; glaucoma (open or closed angle); history of pyloric or urinary bladder neck obstruction; intestinal obstruction; difficulty swallowing; stomach or bowel problems (e.g, blockage, muscle weakness, ulcerative colitis, Crohn's disease); bleeding disorders; acid reflux disease; myasthenia gravis; allergy to belladonna alkaloids; impaired hepatic or renal function.
Any condition that would, in the opinion of the Principal Investigator (PI) or MAI, place the subject at an unacceptable risk of injury or render the subject unable to meet the requirements of the protocol.
Inability to communicate or cooperate with the investigators.
Medical history of significant dermatologic diseases or conditions, such as atopy, psoriasis, vitiligo or conditions known to alter skin appearance or physiologic response (e.g. diabetes, porphyria).

Subject has an obvious difference in skin color at patch sites (compared to neighboring skin), or the presence of a skin condition, excessive hair at the application site, sunburn, raised moles and scars, open sores at application site, scar tissue, tattoo, or coloration that would interfere with placement of test articles, or the assessment of the skin and/or reactions to drug.
