What this means
- 01
FDA has approved Therapeutic Plasma Exchange for at least one labeled indication, so a pharmaceutical-grade product exists in the United States and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What Therapeutic Plasma Exchange is
An established medical procedure that removes plasma and replaces it with albumin. A 347-patient randomised trial in Alzheimer disease met one of two co-primary endpoints, and two small 2025 randomised trials of ageing biomarkers reached opposite conclusions.
Therapeutic plasma exchange is not experimental as a procedure. It is a standard treatment used in neurology, haematology and nephrology, performed with cleared apheresis equipment, in which a volume of the patient's plasma is removed and replaced with albumin, or albumin plus intravenous immunoglobulin.
Mechanism: Two competing accounts, neither settled in humans. The dilution account, developed in mice, holds that removing a fraction of old plasma dilutes age-elevated autoregulatory proteins and resets systemic signalling, and that the replacement fluid is secondary; the 2020 mouse work found that saline plus albumin exchange matched the effects of young blood.
Regulatory history: Therapeutic plasma exchange is an established medical procedure performed with cleared apheresis devices and has recognised indications in neurological, haematological and renal disease. It is not approved for ageing, biological age reduction or Alzheimer disease anywhere.
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
