RegistryTwo registry identifiers apply; see trials[]. A single record-level registry field cannot represent both.

Identifiers: this record covers more than one registered trial. Identifiers, population, recruitment status and primary outcome are listed separately per trial below, because they differ.

AFFIRM

RegistryNCT03430037

Verified viaClinicalTrials.gov v2 API, 2026-08-08

Identifiers: DOI not applicable to this study type; PMID not applicable to this study type; trial registry id verified. Record-level verification and identifier-level status are separate: a record can be fully verified against its primary publication while an identifier that cannot apply to the study type — a trial registry ID for an animal study, for instance — is marked not applicable. No identifier is fabricated, and none is left in a “pending” state.

Not the same study

AFFIRM and AFFIRM-LITE are two separately registered Mayo Clinic trials, not one trial with two names. They differ in enrolled population and in primary outcome measure: AFFIRM enrolls postmenopausal women and measures 6-minute walk / gait speed at 1 month; AFFIRM-LITE enrols adults of both sexes and measures percent change in blood inflammation markers at 7 days. Neither has published results as of the search date, so no efficacy conclusion is available from either.

Five-qualifier claim

Species / populationOlder adults with frailty/multimorbidity (older women in AFFIRM; mixed cohort in AFFIRM-LITE).
Exposure, route, scheduleOral fisetin 20 mg/kg/day for 2 consecutive days in both trials, but AFFIRM repeats the 2-day course in a second consecutive month while AFFIRM-LITE does not. See the per-trial rows.
Comparator / durationBoth are randomized, double-masked and placebo-controlled. The measurement points differ: AFFIRM reads out at 1 month, AFFIRM-LITE at 7 days.
Endpoint / numeric resultEach trial has its own primary outcome measure -- see the per-trial rows. Both are enrolled/ongoing with no efficacy results published as of the search date.
What it did NOT establishNo results — the existence of the trial is not evidence of benefit.
