      This study is a multi-center, randomized, triple blind placebo-control with parallel groups.&#xD;
      Patients diagnosed with mild to moderate AD will be enrolled and randomly assigned in a&#xD;
      blinded fashion to receive study drug APH-1105. Groups will receive either 0.5 µg (15 active,&#xD;
      5 placebo), 1.0 µg (15 active, 5 placebo), or 2.0 µg (15 active, 5 placebo). A full&#xD;
      assessment will be made of all relevant tolerability and safety data.&#xD;
&#xD;
      Patients will be administered the study drug outside of the clinic setting by a study partner&#xD;
      twice a week. The initial dose of APH-1105 will take place in a clinic setting for the&#xD;
      purpose of collecting initial Pharmacokinetic data.&#xD;
&#xD;
      The total duration for patient participation will be approximately 18 weeks which includes 1&#xD;
      week for screening, 12 weeks of treatment and followup 4 weeks post final dose. Study visits&#xD;
      will occur during screening, baseline, weeks 1, 2, 4, 8, 12 and 16 for a total of 7 visits.&#xD;
      Week 16 represents the followup visit after the final dose of study medication.&#xD;
&#xD;
      Cognitive assessments will be performed at screening, and will repeat at weeks 4, 12 and 16.&#xD;
      Behavioral Functioning and Quality of Life measures will be done at weeks 2,4,8,12 and 16.&#xD;
&#xD;
      Blood samples will collected though out the study for Pharmacokinetic analyses.&#xD;

The Behavioral Pathology in Alzheimer's Disease Frequency Weighted Severity Scale (BEHAVE-AD-FW) assesses the possible neurological basis of behavioral and psychological symptoms of dementia, the relationships between behavioral functioning and cognitive functioning. The scale consists of seven (7) behavioral categories (paranoid and delusional ideation, hallucinations, activity disturbances, aggressiveness, diurnal rhythm disturbances, affective disturbances, anxieties, and phobias) and consists of twenty-five (25) symptoms grouped into these categories. Items are score on a 4 point severity - higher the score, higher the impairment.</description>

    <description>Change in the Clinical Global Impression of Improvement (CGI-I) and the Caregiver Clinical Global Impression of Improvement (CGI-I) is a 3-item observer-rated scale that measures illness severity, global improvement or change, and therapeutic response. It is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through to 7 (amongst the most severely ill patients). CGI-C scores range from 1 (very much improved) through to 7 (very much worse). Each component of the CGI is rated separately; the instrument does not yield a global score.</description>

    <description>The Columbia-Suicide Severity Rating Scale (C-SSRS) is an assessment tool that evaluates suicidal ideation and behavior. It is comprised of ten categories, with binary responses (yes/no) to indicate a presence or absence of the behavior. The ten categories included in the C-SSRS are as follows: Category 1 - Wish to be Dead; Category 2 - Non-specific Active Suicidal Thoughts; Category 3 - Active Suicidal Ideation with Any Methods (Not Plan) without Intent to Act; Category 4 - Active Suicidal Ideation with Some Intent to Act, without Specific Plan; Category 5 - Active Suicidal Ideation with Specific Plan and Intent; Category 6 - Preparatory Acts or Behavior; Category 7 - Aborted Attempt; Category 8 - Interrupted Attempt; Category 9 - Actual Attempt (non-fatal); Category 10 - Completed Suicide. A yes/no binary response is also utilized in assessing self-injurious behavior without suicidal intent. The outcome of the C-SSRS is a numerical score obtained from the these categories.</description>

time frame: Baseline, week 4, 8 12 and week 16 post final dose.
description: Change in the Behavioral Pathology in Alzheimer's Disease Rating Scale -Frequency-Weighted (BEHAVE-AD-FW). The Behavioral Pathology in Alzheimer's Disease Frequency Weighted Severity Scale (BEHAVE-AD-FW) assesses the possible neurological basis of behavioral and psychological symptoms of dementia, the relationships between behavioral functioning and cognitive functioning. The scale consists of seven (7) behavioral categories (paranoid and delusional ideation, hallucinations, activity disturbances, aggressiveness, diurnal rhythm disturbances, affective disturbances, anxieties, and phobias) and consists of twenty-five (25) symptoms grouped into these categories. Items are score on a 4 point severity - higher the score, higher the impairment.
measure: Change in Behavioral Disturbance
time frame: Baseline, week 4, 8 12 and week 16 post final dose.
description: Change in the Neuropsychiatric Inventory (NPI) The Neuropsychiatric Inventory (12 item) is a caregiver/informant-based interview that assesses 12 neuro-psychiatric symptoms of the participant over the previous month. Responses are rated both in terms of frequency (1=rarely, less than once per week; 2=sometimes, about once per week; 3=often, several times per week; and 4=very often, once or more per day) and severity (1=mild; 2=moderate; 3=severe) with composite scores ranging from 0-144. The higher the score the greater symptom severity.
measure: Change in Dementia Symptom Severity
time frame: Baseline, week 4, 8 12 and week 16 post final dose.
description: Change in the Clinical Dementia Rating Scale(CDR_SB) The Clinical Dementia Rating or CDR measure the stage severity of dementia. It is a five-point scale in which "0" connotes no cognitive impairment, and then the remaining four points are for various stages of dementia, mild to severe.
measure: Evaluate the Quality of Life Status
time frame: Baseline, week 4, 8, 12 and week 16 post final dose
description: Change in the Clinical Global Impression of Improvement (CGI-I) and the Caregiver Clinical Global Impression of Improvement (CGI-I) is a 3-item observer-rated scale that measures illness severity, global improvement or change, and therapeutic response. It is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through to 7 (amongst the most severely ill patients). CGI-C scores range from 1 (very much improved) through to 7 (very much worse). Each component of the CGI is rated separately; the instrument does not yield a global score.
measure: Risk of Suicide
time frame: Baseline, week 4, 8, 12 and week 16 post final dose
description: The Columbia-Suicide Severity Rating Scale (C-SSRS) is an assessment tool that evaluates suicidal ideation and behavior. It is comprised of ten categories, with binary responses (yes/no) to indicate a presence or absence of the behavior. The ten categories included in the C-SSRS are as follows: Category 1 - Wish to be Dead; Category 2 - Non-specific Active Suicidal Thoughts; Category 3 - Active Suicidal Ideation with Any Methods (Not Plan) without Intent to Act; Category 4 - Active Suicidal Ideation with Some Intent to Act, without Specific Plan; Category 5 - Active Suicidal Ideation with Specific Plan and Intent; Category 6 - Preparatory Acts or Behavior; Category 7 - Aborted Attempt; Category 8 - Interrupted Attempt; Category 9 - Actual Attempt (non-fatal); Category 10 - Completed Suicide. A yes/no binary response is also utilized in assessing self-injurious behavior without suicidal intent. The outcome of the C-SSRS is a numerical score obtained from the these categories.
