Allocation: | N/A |
: | This study is an open-label pilot study of intermittent D+Q to measure its target engagement in CSF and blood, and to establish the feasibility and safety of D+Q treatment in older adults with early stage AD as initial proof-of-concept for a larger Phase 2 clinical trial. |
Primary Purpose: | Treatment |
Masking: | None (Open Label) |
Arm | Intervention/treatment |
---|---|
Experimental: Intermittent D+Q Senolytic treatment in 5 individuals with early AD to determine levels of drug that reach the central nervous system (CNS) by collecting cerebral spinal fluid (CSF), and begin collecting initial data on target engagement of senescent cells, AD-related markers, and AD-relevant outcomes for future trials. | Drug: Intermittent D+Q Intermittent D+Q administered for 2 days on/14 days off for 12 weeks (6 cycles) |
Ages Eligible for Study: | 65 Years to 65 Years |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Criteria: | Inclusion Criteria: 1. Age 65 years or above. 2. Clinical diagnosis of AD (MoCA 10-18 and Clinical Dementia Rating Scale/CDR = 1) on a stable dose of cholinesterase inhibitors for at least three months 3. Body Mass Index (BMI) within range of 19 - 35 kg/ m2 4. Labs: Normal blood cell counts without clinically significant excursions (WBCs: 4,500-10,500 cells/mcL; absolute neutrophil count: 1,800-8,700 cells/mcL; platelets: 140-450 K/uL; hemoglobin 12.0-17.5 grams/dL); liver and renal function (AST 10-40 IU/L, total bilirubin 0.1-1.4 mg/dl); cholesterol (<240 mg/dl), triglycerides (<300 mg/dl), and glucose control (HbA1c < 7%). PT/PTT/INR within normal limits 5. Participants must be accompanied by a Legally Authorized Representative designated to sign informed consent and to provide study partner reported outcomes at all remaining visits 6. Participants must have no plans to travel over the next 4-5 months that interfere with study visits following consent Exclusion Criteria: 1. Hearing, vision, or motor deficits despite corrective devices; 2. Alcohol or drug abuse; 3. MRI contraindications; 4. Myocardial infarction, angina, stroke or transient ischemic attack in the past 6 months; QT interval >440 on ECG will not be enrolled. Chronic heart failure will be exclusionary; 5. Participants with coagulation disorders; 6. Neurologic, musculoskeletal, or other condition that limits subject's ability to complete study physical assessments; 7. Uncontrolled diabetes (HbA1c > 7% or the current use of insulin); 8. Current or chronic history of liver disease, or known hepatic or biliary abnormalities; 9. Use of anti-arrhythmic medications known to cause QTc prolongation, anti-platelet or anti-coagulant medication; 10. Current use of quinolone antibiotics. 11. Poorly controlled blood pressure (systolic BP>160, diastolic BP>90 mmHg). 12. Active inflammatory, autoimmune, infectious, hepatic, gastrointestinal, malignant, and psychiatric disease. 13. History of or MRI-positive for any space occupying lesion, including mass effect or abnormal intracranial pressure, which would indicate contraindication to lumbar puncture |
