💬In plain words
What the trial is, and whether it could suit you
Specific Aim 1: To test the hypothesis that prolonged (3-month) treatment with galantamine inhibits NADPH IsoLG-protein adducts formation and improves markers of endothelial cell (EC) dysfunction in AAs.
Aim 1a: The investigators will determine if galantamine inhibits NADPH IsoLG-protein adducts formation, superoxide production, and immune cell activation compared to placebo.
For this purpose, the investigators will study peripheral blood mononuclear cell (PBMC), a critical source of systemic oxidative stress, collected from study participants.
Aim 1b: The investigators will determine if galantamine reduces intracellular Iso-LGs, ICAM-1, and 3-nitrotyrosine, a marker of vascular oxidative stress, in ECs harvested from study participants.
Specific Aim 2: To determine if prolonged (3-month) treatment with galantamine improves endothelial dysfunction as measured by vascular reactivity i

📋 Eligibility rules (as published)
Inclusion Criteria:
1. African American women and men
2. Age 18 to 60 years old
3. BMI \>28
Exclusion Criteria:
1. Individuals with a history of physician diagnosed myocardial infarction, angina, heart failure, stroke, or transient ischemic attack, or who had undergone an invasive procedure for CVD (coronary artery bypass graft, angioplasty, valve replacement, pacemaker placement or other vascular surgeries)
2. Uncontrolled hypertension defined as persistent blood pressure \>140/90 despite the use of anti-hypertensive agents.
3. Diabetes Mellitus type 1 or type 2, as defined by a fasting plasma glucose of 126 mg/dL or greater hemoglobin A1C (HbA1C) 6.5% or above or the use of anti-diabetic medication
4. The use of nitrates.
5. The metabolism of galantamine is primarily through the cytochrome P450 system, specifically the CYP2D6 and CYP3A4 isoenzymes. We will exclude subjects who have impaired hepatic function and/or who are currently using strong inhibitors of CYP3A4 and CYP2D6 (e.g. ketoconazole and paroxetine, respectively).
6. Pregnancy or breast-feeding. Women of child-bearing potential will be required to have undergone tubal ligation or to be using an oral contraceptive or barrier methods of birth control.
7. Post-menopausal women.
8. The use of any other central or peripheral acetylcholinesterase inhibitor (donezepil (Aricept(R)), pyridostigmine (Mestinon(R)), rivastigmine (Exelon(R)), tacrine (Cognex(R)).
9. First, second or third-degree AV block detected during the screening visit with an ECG
10. Seizures or history of seizures.
11. Current smokers defined as those who smoked a cigarette in the last 30 days.
12. History of recurrent syncope.
13. History of serious neurologic disease such as cerebral hemorrhage, stroke, or transient ischemic attack.
14. History of cardiac shunts.
15. Allergy to eggs or soy.
16. Impaired hepatic function (aspartate amino transaminase \[AST\] and/or alanine amino transaminase \[ALT\] \>3.0 x upper limit of normal range)
17. Impaired renal function test (eGFR\<60 mL/min/1.73m2)
18. Anemia (hematocrit \<34%)
19. Ongoing substance abuse.
20. Treatment with any investigational drug in the one month preceding the study
21. Mental conditions rendering a subject unable to understand the nature, scope and possible consequences of the study
22. Inability to comply with the protocol, e.g. uncooperative attitude, inability to return for follow-up visits, and unlikelihood of completing the study
