About this trial

This is an interventional treatment trial for Alzheimer's Disease focused on measuring Alzheimer's, bryostatin, PKC epsilon

Eligibility Criteria

50 Years - 85 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Male or female, age 50 - 85 yrs. Females are non-childbearing potential

  • Significant neuroimaging abnormalities, previously known or discovered on screening MRI scan,
  • Evidence of clinically significant unstable cardiovascular, renal, hepatic, gastrointestinal, neurological, or metabolic disease within the past 6 months
  • Use of any drug within 14 days prior to randomization unless the dose of the drug and the condition being treated have been stable for at least 30 days and are expected to remain stable during the study

Outcomes

Primary Outcome Measures

Number of Participants With Adverse Events as a Measure of Safety and Tolerability
Evaluate the safety and tolerability of bryostatin 1 (hereinafter referred to as bryostatin) in patients with Alzheimer's Disease (AD) following a single intravenous (IV) dose.
Preliminary Efficacy of a Single Dose of Bryostatin in the Treatment of Patients With AD
Hopkins Verbal Learning Test - Revised (HVLT-R) delayed recall; change from baseline. HVLT consists of a 12-item word list drawn from 3 semantic categories, presented in 3 learning trials. Score range = 0-12. The lower the number, the more impaired. Repeatable Battery of Assessments for Neuropsychological Status (RBANS) figure recall; change from baseline. Total Score Range: 0-20. Each portion of the drawing is scored 1 point for correctness and completeness and 1 point for being placed properly in relation to the rest of the drawing. Drawing and placement scores are summed for the item total. To obtain subtest total score, the drawing and placement scores are summed for each item. The lower the number, the more impaired.

Secondary Outcome Measures

Preliminary Efficacy of a Single Dose of Bryostatin in the Treatment of Patients With AD
HVLT-R (Hopkins Verbal Learning Test-Revised™) delayed recall (change from baseline). A 12-item word list: 3 learning trials. Score range = 0-12. The lower the number, the more impaired. Repeatable Battery of Assessments for Neuropsychological Status (RBANS) figure recall; change from baseline. Score Range: 0-20. The lower the number, the more impaired. Digit Symbol Coding (observed), Score range: 0-125. The lower the number, the more impaired. Clinical Dementia Rating- Sum of Boxes (CDR-SB, observed). Sum of 6 investigated domains (Memory, Orientation, Judgment and Problem Solving, Community Affairs, Home and Hobbies, Personal Care). Each subtest range is 0-3; Sum of all 6 subtest scores gives total CDR-SB score (range= 0-18).The higher the number, the more impaired. Mini Mental State Exam, version 2 (MMSE-2), change from baseline. The MMSE-2 measures aspects of cognitionon a scale of 0-30. Lower scores indicate greater cognitive impairment.

5. Study Description

Brief Summary
This study is being done to evaluate the safety, tolerability and potential effectiveness of a new investigational drug, bryostatin 1, in patients with Alzheimer's disease (AD).
Detailed Description
This study is a single center, randomized, double-blind, placebo-controlled, parallel groups trial in patients with AD. Each subject enrolled in the trial will be randomized to receive a single IV dose of 0 (placebo) or 25 μg/m2 bryostatin. A total of 15 subjects (5 in the placebo arm and 10 in the treatment arm) will be enrolled in the study. The study consists of screening evaluations and on study evaluations divided into two segments, an inpatient segment and an outpatient segment. The four-day inpatient segment will consist of baseline evaluations and a 1-hour IV infusion of study drug followed by evaluations at multiple evaluations over the first 72 hrs post dose. During the outpatient segment, patients will be followed for AEs and have a final evaluation at 2 weeks post dose and a 4-week telephone safety follow up. Evaluations will include safety, efficacy, pharmacokinetics, and pharmacodynamics as assessed by PKC activity
