Brief summary

This research project is being conducted to look at evaluate the Pharmacokinetics (PK) and Safety of Two Formulations of a 7-Day Application of Memantine Transdermal Delivery System (TDS) Compared to Oral Administration of NAMENDA XR and to assess TDS adhesion in Healthy 50-80 year old Volunteers

Interventions

Part A Treatment A: Formulation A - Memantine TDS 362, 50 cm2 22 mg/day target dose (comprising three x patches for a total application area of 150 cm2) worn for seven days, four or three days. Treatment B: Formulation B - Memantine TDS 360, 50 cm2 18 mg/day target dose (comprising three x patches for a total application area of 150 cm2) worn for seven days. Treatment C: Comparator – (Memantine Hydrochloride) 28 mg (NAMENDA XR), as a daily oral dose for seven days. Part B Treatment D1: Memantine

Part A Treatment A: Formulation A - Memantine TDS 362, 50 cm2 22 mg/day target dose (comprising three x patches for a total application area of 150 cm2) worn for seven days, four or three days. Treatment B: Formulation B - Memantine TDS 360, 50 cm2 18 mg/day target dose (comprising three x patches for a total application area of 150 cm2) worn for seven days. Treatment C: Comparator – (Memantine Hydrochloride) 28 mg (NAMENDA XR), as a daily oral dose for seven days. Part B Treatment D1: Memantine TDS 362 with backing laminate 1, 150 cm2 22 mg/day target dose (comprising one x patch, total application area 150 cm2) worn for three days. There will be a washout period of ast least 15 days between treatments. (Monitoring to adherence not required since the IP is a patch formulation). Patch is applied to the backs of subjects Part C Treatment D1: Memantine TDS 362 with backing laminate 1, 150 cm2 22 mg/day target dose will be applied to the back and worn for three days. The patch will be removed on Day 4. A new Memantine TDS 362 treatment will be applied to the opposite side of the previous patch and will be worn for seven days. Part D Treatment D1: Memantine TDS 362 with backing laminate 1, 150 cm2 22 mg/day target dose worn for seven days

Inclusion criteria

Part A and B - Inclusion Criteria A. General * Caucasian male or female with light/pale skin aged 50 to 80 years (inclusive) on the day of randomization. * Has a Body Mass Index (BMI) between 18-34 kg/m^2 (inclusive) as calculated using the site standard procedures. * Must be willing and able to understand and participate in all scheduled evaluations by providing a signed and dated written informed consent prior to the initiation of any study procedures. B. Contraception and Concomitant Medications * Women and men of child-bearing potential must agree to use adequate contraception prior to study entry, for the duration of study participation, and for ninety days following completion of therapy. Postmenopausal status will be verified by the absence of the menstrual cycle for twelve consecutive months or medical documentation of an oophorectomy or hysterectomy or bilateral tubal ligation and follicle-stimulating hormone FSH blood test at screening. FSH must be > 25.8 mIU/mL. * If the subject is receiving allowed medications for the treatment of non-excluded medical conditions, must be stable for at least 28 days before randomization on Day 1. Any medications not at stable dose for at least 28 days, must be discontinued with a 5 x half-life washout and Sponsor approval prior to randomization on Day 1. Permitted medications must be consistent with the current label for oral Memantine (Namenda XR) tablets. * Negative urine drug screen for drugs of abuse (list as per protocol) unless there is documentation that the subject has been prescribed the corresponding medication and the medication is otherwise acceptable for the study.

Exclusion criteria

Exclusion Criteria A .General * Participation in another clinical study with an investigational product or device within sixty days prior to screening. * Plasma donation within 28 days of screening or any blood donation or blood loss greater than 500 mL within three months of screening. * Has skin color or tone that may not allow reliable evaluation of irritation. * Unwilling to abstain from strenuous physical exercise and from alcohol consumption for forty eight hours prior to scheduled PK blood draws at the clinic visits. * Has intolerance to venipuncture and/or inability to comply with the extensive blood sampling required for this study or does not have suitable veins in both arms. * Has cuts, scratches/abrasions, scars, breaks in the skin surface, recent tattoos (within last six months) at the application site, skin with excessive hair, indications of sunburn, excessive skin tanning, stretch marks, moles and/or similar abnormalities at the intended application sites which would affect absorption of the Investigational Product. * Unwilling to refrain from using tanning salons, saunas, or sunbathe during the conduct of the study. Unwilling to also refrain from shaving of application site, waxing of application site, or using lotion hair remover on or near application site from twenty one days before patch application and during the conduct of the study. * Smoke more than twenty cigarettes per day B. Medical History * Presence of any major psychiatric disorder if, in the opinion of the Investigator, the psychiatric disorder or symptom is likely to confound interpretation of drug effect/tolerability, or affect the subject’s ability to complete the study. * Significant cardiovascular disease, including moderate or severe congestive heart failure (ejection fraction of less than 40%) or clinically significant stenosis or occlusion of a carotid or vertebral artery. * Significant or chronic lung disease, including Chronic Obstructive Pulmonary Disease (COPD) and severe or unstable asthma. * Diabetes complicated with retinopathy (by history), neuropathy (by history or physical examination), or nephropathy (by serum creatinine greater than ULN or proteinuria greater than0.2 g/L). Uncomplicated, stable diabetes that is well controlled and actively managed is not exclusionary. * Known or suspected systemic infection, including human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV), or tuberculosis (TB) or qualitative syphilis test as judged by the Investigator at screening. * History of severe allergy/hypersensitivity reactions or on-going allergy/hypersensitivity reactions, or history of hypersensitivity to Memantine or other drugs of the N-methyl-D-aspartate (NMDA) antagonist class. * History of cancer within five years of screening or between screening and randomization.
