Autologous Activated Adipose-derived Stem Cells (RB-ADSC) Injected Directly Into the Brain for Mild to Moderate Alzheimer's Disease
What this study is about
This is a research study to evaluate the safety of an experimental autologous cell product obtained from participant's own adipose tissue as a possible treatment for Alzheimer disease.
View original scientific description
This is a research study to evaluate the safety of an investigational autologous cell product obtained from participant's own adipose tissue as a possible treatment for Alzheimer disease.
Interventions
BIOLOGICAL
RB-ADSC
Ex Vivo Expanded, Autologous Adipose-Derived Stem Cells (ADSCs)
Primary outcome measures
The safety of RB-ADSC treatment in study participants with AD
Time frame: up to 28 weeks
Safety will be determined by incidence, type and severity of adverse events (AE) and serious adverse events (SAE) graded according to CTCAE v5.0 and CRS revised grading system and defined by clinical relevant findings at every visit and week 28 post-treatment in physical examination, vital signs and laboratory data

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
