SeneSIQ — cellular-senescence & senolytics evidence reference

No senolytic has a human lifespan RCT. Lifespan-extension evidence is animal-only. Human trials to date are small pilots or early-phase studies with feasibility, biomarker, or disease endpoints — including one failed Phase 2. Every intervention page shows this plainly.

Evidence tiers

Tier	Label	Note
1	Human lifespan / clinical-outcome RCT	Randomized, hard clinical/lifespan endpoint. NONE exist for any senolytic/senomorphic as of the search date.
2	Human RCT — disease or biomarker endpoint	Randomized, but endpoint is a disease score or biomarker, not lifespan.
3	Human open-label pilot (feasibility / biomarker)	Small, non-randomized; feasibility, tolerability, or senescent-cell biomarker change.
4	Human observational / mechanistic	Cohort, cross-sectional, or ex-vivo human tissue.
5	Replicated animal lifespan study	Median/maximum lifespan change in an animal model, replicated.
6	Animal healthspan / mechanism study	Function, pathology, or senescent-cell clearance in an animal model; not a lifespan endpoint.
7	In vitro / ex vivo	Cell-culture senolysis or mechanism; no whole-organism outcome.
