Clinical trial Recruiting at 1 site Early Phase 1 Interventional Ages 50 to 75

Intravenous umbilical cord blood cell infusion alongside standard Alzheimer's medication

Official title: A Randomized Double-blind Clinical Study on the Use of Umbilical Cord Blood as an Adjuvant Therapy to Improve Cognitive Function in Alzheimer's Disease and Its Mechanism of Action

Run by Anhui Provincial Hospital · NCT07208344 · Data updated 2026-11-12

This trial will try giving an IV infusion of umbilical cord blood mononuclear cells to people aged 50–75 with mild to moderate Alzheimer's alongside their usual medications to see if it helps symptoms or biological disease markers.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are 50–75 years old with mild to moderate Alzheimer's confirmed by a positive amyloid PET, an MMSE of 15–30, a reliable caregiver, and the ability to complete study visits and tests.

Probably not a fit

Patients with dementias due to other causes, major systemic illnesses, or other exclusion criteria are unlikely to benefit and are not eligible for the intervention.

What this trial studies

This single-center, randomized, double-blind early phase 1 trial will enroll 30 AT(N)-confirmed Alzheimer's patients and randomize them equally to low-dose, high-dose, or control groups. All participants continue conventional cholinesterase therapies while receiving one of the blinded interventions: processed umbilical cord blood mononuclear cell infusions or control. The cord blood product is obtained from a certified bank and processed to deplete erythrocytes and granulocytes to reduce immunogenicity; baseline clinical assessments, single-cell omics sampling, and optional CSF collection are planned. The study focuses on safety and preliminary signals of biological or clinical effect from the cell infusions.

Why it matters

Potential benefit: If successful, the infusions could slow cognitive decline or improve clinical and biological measures beyond standard medications.

How similar studies have gone: Preclinical work and a few small early-phase human studies of cord blood or related cell therapies have shown safety and suggestive biological signals, but clear clinical benefit in Alzheimer's has not been established.
