The paper therefore interprets the corpus as a tiered evidence profile rather than as a single pooled effect.\n\nThe conclusion is that ABT-263 remains a bounded geroscience case: the retained clinical and mechanistic evidence profile defines the scope for targeted testing, while mixed and null findings limit any unqualified anti-aging claim.\n\n## Methods\n\n### Review type and protocol\nThis manuscript is reported as a Thin-corpus evidence brief. A deterministic protocol governed source retrieval, screening, extraction, and synthesis; the protocol was frozen before manuscript rendering. The full audit trail is in the supplementary `methods_pack.json` and the timestamped submission directory `synthesis-senolytics-v06-DAILY-2026-06-25T00-24-59Z`.\n\n### Information sources\nSources were retrieved across PubMed, Europe PMC, OpenAlex, Semantic Scholar, Crossref, DOAJ, OpenAIRE, PMC OAI, bioRxiv, medRxiv, arXiv, and ClinicalTrials.gov. Retrieval window: 2026-06-25.\n\n### Search strategy\nThe following topic-anchored queries were executed against the information sources listed above:\n\n- `senolytic AND aging AND human`\n- `(dasatinib AND quercetin) AND aging`\n- `fisetin AND senescence AND aging`\n- `navitoclax AND senescent AND clinical`\n- `senolytic AND clinical trial AND randomized`\n- `(senolytic OR senescence) AND (longevity OR healthspan)`\n- `(p16 OR SASP OR senescent cell) AND human AND clinical`\n- `senotherapeutic AND older adults AND trial`\n- `(senescent cell OR SASP) AND frailty AND human`\n- `(dasatinib OR quercetin OR fisetin) AND safety AND tolerability`\n- (... 5 additional queries; see `methods_pack.json` for the full list)\n\n### Eligibility criteria\n- Sources whose primary content addresses senolytics.\n- Sources with extractable quantitative or qualitative findings.\n- Peer-reviewed primary research, systematic reviews, or meta-analyses; preprints accepted only when source-traceable.\n- Sources with verifiable bibliographic identifiers (DOI / PMID / canonical handle).\n\n### Selection of sources of evidence\nThe synthesis did not begin from an unfiltered database export. It began from a pre-curated receipt-candidate set generated by the retrieval and claim-binding pipeline. Of 646 records in the receipt-candidate union, 614 were classified as source candidates and 33 were admitted as traceable synthesis sources. Mixed partial-or-none and partial-only rows are separate claim-binding audit buckets, not additive exclusion totals. No additional records were excluded after final source admission.\n\n### source admission funnel\n\n| Admission bucket | n |\n|---|---:|\n| Receipt candidate union | 646 |\n| Classified source candidates | 614 |\n| No extractable claims | 26 |\n| None-only claim binding | 1 |\n| Mixed partial-or-none claim-binding candidates | 25 |\n| Partial-only claim-binding candidates | 9 |\n| Strict high-confidence sources | 4 |\n| Admitted final sources | 33 |\n\n### Exclusion reasons\n- No records were excluded at the gates instrumented for this run: the eligibility criteria above were applied during retrieval and claim-binding but produced no post-screening exclusions with recorded counts for this corpus.\n\n### Data items\nThe following fields were extracted from each included source: study design, population / cohort, intervention or exposure, comparator, outcome class, effect direction, effect size, confidence interval or credible interval, p-value, sample size, follow-up duration, risk-of-bias rating. Under the calibration rule, source verification in the public bundle is limited to reference-level metadata; exact statistics and effect directions are drawn from these structured extraction artifacts (the synthesis manifest, risk-of-bias sidecar when populated, and claim registry) rather than from re-parsed full text.\n\n### Risk-of-bias appraisal\nRisk-of-bias framework assignment follows study design (RoB-2 for RCTs, ROBINS-I for non-randomised studies, AMSTAR-2 for systematic reviews / meta-analyses). Public appraisal claims are limited to populated `risk_of_bias.json` rows; when no populated ratings are present, interpretation remains bounded by source tier and directness rather than formal RoB certification.\n\n### Synthesis approach\nEvidence-tension synthesis: claims grouped by outcome class (cardiometabolic, contextual adjacent evidence, deficiency prevalence, immune and inflammation, longevity, mechanism, skeletal, fracture, and bone); within-class agreement, disagreement, and directness gaps surfaced explicitly. Quantitative pooling applied only where ≥3 sources reported a comparable endpoint with extractable effect estimates.\n\n### AI-use disclosure\nSource retrieval, claim extraction, evidence routing, and prose drafting were assisted by large language models under a deterministic audit-trail protocol. Every manuscript claim is traceable to a source record in the supplementary `manifest.json`. Final eligibility and interpretation decisions are author-verified.\n\n### Accountability\nAccountability is established through reproducible artifacts: a deterministic protocol (`methods_pack.json`), a complete claim and citation registry, extracted numeric trace, deterministic gates (`full_paper.journal_surface.json`, `pre_submit_gate.json`, `artifact_consistency.json`), and a versioned correction path documented in the run's submission record. Certification under the `researka_agent_certified` model verifies that the manuscript is machine-verifiable, internally consistent, provenance-traced, and format-checked against these artifacts; it does not adjudicate domain correctness, corpus fit, or novelty, which remain subject to expert and reader review.\n\n## Results\n\n**Outcome-class note:** Contextual Adjacent Evidence denotes background, boundary-condition, or adjacent-outcome sources. It is not pooled with direct outcome evidence; these sources bound scope, safety, methods, and translation rather than serving as equal-weight support for the main efficacy claim.\n\n| Evidence domain | Corpus slice | Strongest signal | Directness | Main limitation |\n|---|---|---|---|---|\n| Contextual Adjacent Evidence | n=14; claims=822 | no extracted directional signal in 11/14 sources | 10 indirect; 1 protocol; 3 review | limited corpus depth in this outcome class |\n| Immune and Inflammation | n=7; claims=138 | no extracted directional signal in 4/7 sources | 1 indirect; 2 mechanistic; 1 protocol; 3 review | limited corpus depth in this outcome class |\n| Mechanism | n=4; claims=47 | no extracted directional signal in 4/4 sources | 4 mechanistic | limited corpus depth in this outcome class |\n| Cardiometabolic | n=3; claims=112 | no extracted directional signal in 3/3 sources | 3 indirect | limited corpus depth in this outcome class |\n| Skeletal, Fracture, and Bone | n=3; claims=118 | no extracted directional signal in 2/3 sources | 1 direct; 2 indirect | limited corpus depth in this outcome class |\n| Deficiency Prevalence | n=1; claims=39 | no extracted directional signal in 1/1 sources | 1 indirect | single-source slice; hypothesis-generating |\n| Longevity | n=1; claims=14 | positive signal in 1/1 sources | 1 indirect | single-source slice; hypothesis-generating |\n\nThis evidence brief reports outcome packets as a map of retained evidence rather than as a full journal Results narrative or pooled effect estimate.\n\n### Contextual Adjacent Evidence Outcomes\n\n14 included sources were assigned to this outcome class. Directional coding: null=11, positive=1, unclear=2. Directness coding: indirect=10, protocol=1, review=3.\n\n### Immune Inflammation Outcomes\n\n2 included sources were assigned to this outcome class. Directional coding: null=2. Directness coding: review=2.\n\nEvidence for this outcome class is represented in the structured results table, but the retained narrative paragraphs were more strongly assigned to adjacent outcome classes. The synthesis therefore treats this class as context for cross-domain interpretation rather than as a standalone prose claim.\n\n### Mechanism Outcomes\n\n4 included sources were assigned to this outcome class. Directional coding: null=4. Directness coding: mechanistic=4.\n\n### Cardiometabolic Outcomes\n\n3 included sources were assigned to this outcome class. Directional coding: null=3. Directness coding: indirect=3.\n\n### Skeletal Fracture Bone Outcomes\n\n3 included sources were assigned to this outcome class. Directional coding: mixed=1, null=2. Directness coding: direct=1, indirect=2.\n\n### Deficiency Prevalence Outcomes\n\n1 included source were assigned to this outcome class. Directional coding: null=1. Directness coding: indirect=1.\n\n### Longevity Outcomes\n\n1 included source were assigned to this outcome class. Directional coding: positive=1. Directness coding: indirect=1.\n\n## Limitations\n\nSingle-source outcome classes (Deficiency Prevalence, Longevity) are treated as hypothesis-generating and receive proportional narrative depth rather than standalone evidentiary weight.\n\n**Verification note:** Reference-only or no-abstract records are treated as verification-limited context, not as equal-weight support for the main claim.\n\nThe curated corpus is heavily skewed toward preclinical and indirect interventional hard-endpoint evidence, and the headline conclusions cannot be re-anchored to long-term, hard-outcome human RCTs. Several trials frequently invoked in the senolytic literature, including extension studies of dasatinib+quercetin in diabetic kidney disease, the SToMP-AD cerebrospinal-fluid penetration study, and the SToMP-AD phase 1 feasibility work, are represented only as protocols or as reports in which the field-relevant clinical endpoints are not powered to confirm or refute efficacy. Consequently, any synthesis-level claim of clinical benefit is built on a thin spine of direct human evidence and a thick base of mechanistic or surrogate work, and the gap between mechanistic plausibility and clinic-ready demonstration cannot be closed from this corpus alone.\n\nSeveral outcome classes rest on a single source, and that single-source status is itself a within-corpus generalization risk that should be foregrounded. The directness asymmetry is also informative: Farr 2024 is the only source coded direct, while the surrounding directness=indirect and directness=mechanistic sources share no common endpoint definition, so a corroborating indirect signal cannot substitute for a missing direct one.\n\nThe populations enrolled in the direct and indirect human evidence are narrow, and the external-validity envelope is correspondingly tight. Shimizu 2025 randomized middle-aged humans to an Agrimonia pilosa extract. Outside these specific disease phenotypes, ages, and sex strata, the corpus offers no direct human signal: healthy community-dwelling older men, younger adults, and pediatric or non-European populations are absent. A substantial fraction of the supporting evidence is animal-only, including Falahatgaroshibi 2026 (male young Wistar rats, 10 and 30 mg/kg). Translational relevance to humans remains uncertain.\n\nEndpoint scope is another hard boundary of this corpus. With the exception of Farr 2024, no source reports a hard clinical endpoint such as incident fracture, myocardial infarction, stroke, sepsis-related mortality, or hospitalization; the field is dominated by surrogate and feasibility endpoints (feasibility, tolerability, biomarker change, single-cell transcriptomics, senescence-associated β-galactosidase activity, senescence-associated secretory phenotype factors, and pharmacokinetic parameters).\n\nFinally, the mechanism-to-clinic gap is itself a corpus-level limitation that no individual RoB column can encode. The result is a corpus in which a coherent mechanistic story is told, but the clinically relevant dose, schedule, target population, and hard outcome remain undefined, and any cross-domain inference from mechanistic or surrogate sources onto a clinical recommendation must be treated as hypothesis-generating rather than evidence-supported.\n\n## Conclusion\n\nFor ABT-263, the final interpretation is deliberately tiered: the retained clinical and mechanistic evidence profile defines a bounded geroscience rationale, but the corpus does not support treating mechanistic target engagement, intermediate biomarkers, and patient-relevant outcomes as interchangeable evidence. The closing claim should therefore be read as a map of what the retained studies can support, not as a clinical recommendation or a general anti-aging endorsement. Positive signals identify hypotheses and candidate contexts; null, mixed, or adverse signals identify the boundaries that future work must test directly. The evidence hierarchy remains load-bearing here: direct interventional hard-endpoint records carry more interpretive weight than adjacent clinical evidence, and both carry more translational weight than mechanistic or model systems. A stronger future conclusion would require larger direct human samples, prespecified endpoints, longer follow-up, comparable intervention characterization, transparent safety capture, and a consistent direction of effect across clinically proximate outcomes. Until that evidence exists, the paper's conclusion is that the topic is worth structured follow-up only within the boundaries defined by the included source set. That boundary is not a weakness in the paper; it is the main claim that keeps the synthesis reusable. Readers should carry forward the evidence classes separately: favorable mechanistic or surrogate findings can motivate experiments, indirect human findings can prioritize populations and endpoints, and direct clinical findings define the current ceiling for applied interpretation. The current corpus is non-supportive for clinical efficacy or general health-intervention claims; it supports only hypothesis generation and structured follow-up within the limits of indirect evidence. Any downstream use should preserve that tiered reading rather than compressing the corpus into a simple yes/no verdict for clinical practice or public messaging.\n\n## What This Synthesis Adds\n\nThis synthesis maps 33 included sources on Senolytics across 8 outcome classes and 46 cross-study disagreements. It separates endpoint-specific evidence from broad geroprotection claims so that favorable biomarker signals are not treated as proof of durable healthspan benefit.\n\nAcross 33 curated reference papers, the evidence base for senolytics shows a context-dependent profile. Positive signals appear in: immune inflammation, longevity. Null findings dominate: contextual other, mechanism. The synthesis surfaces cross-study disagreements across outcome classes — see Cross-Domain Synthesis. The senolytics anti-aging case as currently constituted is incomplete: mechanistic plausibility coexists with mixed or sparse human-RCT evidence, and the boundary conditions remain to be established.\n\nAdditional corpus sources included animal/preclinical evidence; the strongest unresolved contrast is the null vs positive between Mahoney 2025 and Schweiger 2025 on contextual adjacent evidence (severity 4/5), which defines the boundary condition future studies must test rather than smooth over.\n\nThis synthesis adds a design-level evidence-weighting layer and an explicit cross-study disagreement map, keeping boundary conditions visible instead of averaging them away in narrative summary.\n\n### Boundary-Condition Matrix\n\n| Evidence domain | Direct sources | Indirect / mechanism sources | Direction profile | Interpretation boundary |\n|---|---:|---:|---|---|\n| longevity | 0 | 1 | positive | direct interventional hard-endpoint gap |\n| cardiometabolic | 0 | 3 | null | direct interventional hard-endpoint gap |\n| immune and inflammation | 0 | 5 | null, positive, unclear | conflict-resolution gap |\n| mechanism | 0 | 4 | null | direct interventional hard-endpoint gap |\n| contextual adjacent evidence | 0 | 14 | null, positive, unclear | conflict-resolution gap |\n| skeletal, fracture, and bone | 1 | 2 | mixed, null | replication gap |\n\n### Evidence-Gap Priority\n\n| Priority | Gap | Rationale |\n|---|---|---|\n| P1 | longevity: direct interventional hard-endpoint gap | 0 direct and 1 indirect source; direction profile: positive |\n| P2 | cardiometabolic: direct interventional hard-endpoint gap | 0 direct and 3 indirect sources; direction profile: null |\n| P3 | immune and inflammation: direct interventional hard-endpoint gap | 0 direct and 2 indirect sources; direction profile: null |\n| P4 | mechanism: direct interventional hard-endpoint gap | 0 direct and 4 indirect sources; direction profile: null |\n| P5 | contextual adjacent evidence: conflict-resolution gap | 0 direct and 14 indirect sources; direction profile: null, positive, unclear |\n\n### Next-Study Design Recommendation\n\nThe next high-yield study for Senolytics should target the **longevity** evidence gap, pre-register the primary endpoint, separate clinical from mechanistic endpoints, preserve safety and adherence capture, and include an analysis plan that can falsify the current boundary-condition claim rather than only confirming a favorable direction. Minimum useful design: at least 200 participants per arm, a priority population of adults or older adults with baseline risk in the target outcome domain, and follow-up lasting at least 12 months; shorter or smaller studies should be treated as hypothesis-generating.\n\n## Tensions and Gaps\n\nAdditional corpus sources included animal/preclinical evidence; evidence-gap priority: The tension analysis separates claim-level disagreement counts from substantive cross-context evidence gaps. Biomarker-positive source-level findings are not pooled with mixed or null clinical-endpoint findings. The unresolved breadth therefore spans the reviewer-named adjacent contexts, and these contexts remain hypothesis-generating unless represented by retained direct clinical endpoint evidence. The manuscript reports 46 claim-level cross-study disagreements from the manifest; that number is a claim-level count, not an independently pooled source-pair count. Actually surfaced tensions include:\n- Fan 2026 vs Farr 2024: surfaced tension/disagreement in Skeletal, Fracture, and Bone because directions are null versus mixed.\n- Falahatgaroshibi 2026 vs Furuuchi 2026: surfaced tension/disagreement in Contextual Adjacent Evidence because directions are unclear versus null.\n- Islam 2023 vs Jean 2024: surfaced tension/disagreement in Immune and Inflammation because directions are positive versus null.\n\n## Evidence Snapshot\n\nSource directness breakdown: 1/33 retained sources directly address the stated topic and aging-relevant hard endpoints; 32/33 are adjacent, contextual, review-level, or mechanistic and are used only to bound interpretation. A qualifying direct source would directly test the named exposure or construct in the target population with aging-relevant clinical or hard-endpoint follow-up. Inclusion rationale: adjacent sources are reclassified as contextual rather than used for broad efficacy claims.\n\n### Source Classification Map\n\n- Additional corpus sources included animal/preclinical evidence; Nambiar 2023: outcome=Contextual Adjacent Evidence; direction=null; directness=indirect; tier=B2.\n- Falahatgaroshibi 2026: outcome=Contextual Adjacent Evidence; direction=unclear; directness=indirect; tier=B2.\n- Sengun 2026: outcome=Contextual Adjacent Evidence; direction=unclear; directness=indirect; tier=B2.\n- Justice 2019: outcome=Contextual Adjacent Evidence; direction=null; directness=indirect; tier=B2.\n- Mahoney 2026: outcome=Contextual Adjacent Evidence; direction=null; directness=indirect; tier=B2.\n- Islam 2023: outcome=Immune and Inflammation; direction=positive; directness=indirect; tier=B2.\n- Zhang 2025: outcome=Contextual Adjacent Evidence; direction=null; directness=indirect; tier=B2.\n- Wakita 2026: outcome=Cardiometabolic; direction=null; directness=indirect; tier=B2.\n- Fan 2026: outcome=Skeletal, Fracture, and Bone; direction=null; directness=indirect; tier=B2.\n- Kawamoto 2026: outcome=Cardiometabolic; direction=null; directness=indirect; tier=B2.\n- Chen 2020: outcome=Contextual Adjacent Evidence; direction=null; directness=review; tier=B2.\n- Lim 2026: outcome=Skeletal, Fracture, and Bone; direction=null; directness=indirect; tier=B2.\n- Novais 2026: outcome=Mechanism; direction=null; directness=mechanistic; tier=C1.\n- Peng 2026: outcome=Contextual Adjacent Evidence; direction=null; directness=indirect; tier=B2.\n- Su 2026: outcome=Deficiency Prevalence; direction=null; directness=indirect; tier=B2.\n- Tripathi 2025: outcome=Contextual Adjacent Evidence; direction=null; directness=indirect; tier=B2.\n- Shimizu 2025: outcome=Contextual Adjacent Evidence; direction=null; directness=indirect; tier=B2.\n- Cadar 2025: outcome=Immune and Inflammation; direction=unclear; directness=mechanistic; tier=C1.\n- Farr 2024: outcome=Skeletal, Fracture, and Bone; direction=mixed; directness=direct; tier=A1.\n- Silva 2024: outcome=Immune and Inflammation; direction=null; directness=protocol; tier=D1.\n- Ichim 2026: outcome=Longevity; direction=positive; directness=indirect; tier=B2.\n- Furuuchi 2026: outcome=Contextual Adjacent Evidence; direction=null; directness=indirect; tier=B2.\n- Gonzales 2022: outcome=Cardiometabolic; direction=null; directness=indirect; tier=B2.\n- Effect of Natural Senolytic 2024: outcome=Contextual Adjacent Evidence; direction=null; directness=review; tier=B2.\n- Delval 2026: outcome=Immune and Inflammation; direction=positive; directness=mechanistic; tier=C1.\n- Schweiger 2025: outcome=Contextual Adjacent Evidence; direction=positive; directness=protocol; tier=D1.\n- Jean 2024: outcome=Immune and Inflammation; direction=null; directness=review; tier=B2.\n- Fang 2023: outcome=Mechanism; direction=null; directness=mechanistic; tier=C1.\n- Mahoney 2025: outcome=Contextual Adjacent Evidence; direction=null; directness=review; tier=B2.\n- Gonzales 2023: outcome=Immune and Inflammation; direction=null; directness=review; tier=B2.\n- Tripathi 2025b: outcome=Immune and Inflammation; direction=null; directness=review; tier=B2.\n- Avila 2024: outcome=Mechanism; direction=null; directness=mechanistic; tier=C1.\n- Miller 2023: outcome=Mechanism; direction=null; directness=mechanistic; tier=C1.\n\nEvidence type metadata note: evidence-type labels are resolved against source excerpts; review, RCT/trial, and excerpt evidence are reclassified under the source classification map before claims are interpreted.\n\nIn animal/preclinical evidence, topic-fit rationale: Sources are retained only when they operationalize senolytics directly or provide adjacent/contextual boundary evidence for the same construct. 1/33 retained sources are classified as direct; adjacent, contextual, review-level, or mechanistic sources are reclassified as boundary evidence rather than used for broad efficacy claims. Representative source-fit checks: Nambiar 2023 (indirect; Contextual Adjacent Evidence), Falahatgaroshibi 2026 (indirect; Contextual Adjacent Evidence), Sengun 2026 (indirect; Contextual Adjacent Evidence), Justice 2019 (indirect; Contextual Adjacent Evidence), Mahoney 2026 (indirect; Contextual Adjacent Evidence).\n\nDirectional coding note: Null or no extracted directional signal means no coded positive, negative, or mixed effect was extracted for that specific outcome class; it is not an absence-of-support finding. Positive, negative, mixed, unclear, and null are outcome-specific codes, so a bounded rationale can be supported by adjacent or different outcome evidence while another outcome remains null or unclear. Contextual claims contain bibliographic background, mechanism, methods, exposure definitions, or population context rather than effect-direction evidence. When an outcome-class summary uses no extracted directional signal, it should state the source proportion, such as X/Y sources, to avoid ambiguity.\n\nThe manuscript foregrounds the load-bearing evidence; the full evidence tables remain in the supplement.\n\n### Load-Bearing Included Studies\n\n- Additional corpus sources included animal/preclinical evidence; Farr 2024; tier=A1; directness=direct; endpoint=skeletal fracture bone; direction=mixed; representative statistic=P = 0.004.\n- Nambiar 2023; tier=B2; directness=indirect; endpoint=contextual adjacent evidence; direction=null.\n- Falahatgaroshibi 2026; tier=B2; directness=indirect; endpoint=contextual adjacent evidence; direction=unclear; representative statistic=P < 0.01.\n- Sengun 2026; tier=B2; directness=indirect; endpoint=contextual adjacent evidence; direction=unclear; representative statistic=P < 0.001.\n- Justice 2019; tier=B2; directness=indirect; endpoint=contextual adjacent evidence; direction=null; representative statistic=p ≤.05.\n- Mahoney 2026; tier=B2; directness=indirect; endpoint=contextual adjacent evidence; direction=null; representative statistic=P = 0.465.\n- Islam 2023; tier=B2; directness=indirect; endpoint=immune inflammation; direction=positive; representative statistic=p ≤ 0.0001.\n- Zhang 2025; tier=B2; directness=indirect; endpoint=contextual adjacent evidence; direction=null.\n- Wakita 2026; tier=B2; directness=indirect; endpoint=cardiometabolic; direction=null.\n- Fan 2026; tier=B2; directness=indirect; endpoint=skeletal fracture bone; direction=null.\n\n### Source Outcome-Class Map\n\nTension-accounting note: disagreement counts are claim-level.

Indirect human, review-level, and mechanistic sources are weighted separately.\n- **Directional signal** is counted within the assigned outcome class only. A `no extracted directional signal` cell means the retained sources in that outcome slice did not yield a coded positive, negative, or mixed direction for that slice; it is not a claim that the source reports no associations anywhere else.\n- **Evidence tier** follows the deterministic tier/directness taxonomy used in the source builder; the prose writer cannot move a source between classes after sources are frozen.\n\n### Load-Bearing Tensions\n\n- Additional corpus sources included animal/preclinical evidence; severity 4 null vs positive: Mahoney 2025 vs Schweiger 2025; Schweiger 2025 (positive on contextual other) vs Mahoney 2025 (null on contextual other) — partial conflict\n- Severity 4 null vs positive: Effect of Natural Senolytic 2024 vs Schweiger 2025; Schweiger 2025 (positive on contextual other) vs Effect of Natural Senolytic 2024 (null on contextual other) — partial conflict\n- Severity 4 null vs positive: Nambiar 2023 vs Schweiger 2025; Schweiger 2025 (positive on contextual other) vs Nambiar 2023 (null on contextual other) — partial conflict\n- Severity 4 null vs positive: Silva 2024 vs Islam 2023; Islam 2023 (positive on immune inflammation) vs Silva 2024 (null on immune inflammation) — partial conflict\n- Severity 4 null vs positive: Shimizu 2025 vs Schweiger 2025; Schweiger 2025 (positive on contextual other) vs Shimizu 2025 (null on contextual other) — partial conflict\n- Severity 4 null vs positive: Schweiger 2025 vs Tripathi 2025; Schweiger 2025 (positive on contextual other) vs Tripathi 2025 (null on contextual other) — partial conflict\n- Severity 4 null vs positive: Schweiger 2025 vs Zhang 2025; Schweiger 2025 (positive on contextual other) vs Zhang 2025 (null on contextual other) — partial conflict\n- Severity 4 null vs positive: Schweiger 2025 vs Peng 2026; Schweiger 2025 (positive on contextual other) vs Peng 2026 (null on contextual other) — partial conflict\n\n## References\n\n- **Nambiar 2023.** _Senolytics dasatinib and quercetin in idiopathic pulmonary fibrosis: results of a phase I, single-blind, single-center, randomized, placebo-controlled pilot trial on feasibility and tolerability._ eBioMedicine, 2023.

IPF is associated with increased senescent cells burden, which may be alleviated with administration of senescent cell targeting drugs termed 'senolytics'. We previously conducted an open-label single-arm pilot study of the senolytic combination of dasatinib and quercetin (D + Q) in patients with IPF but lack of control group limited interpretation and next-stage trial planning. The primary objective of this confirmatory randomized placebo-controlled pilot trial (RCT; NCT02874989) was to report adverse events with D + Q and inform study feasibility for future efficacy trials. METHODS: Twelve participants with IPF aged >50 years were blinded and randomized at a 1:1 ratio to either receive three weeks of D + Q (D: 100 mg/d and Q: 1250 mg/d, three consecutive days per week) or matching placebo. FINDINGS: All participants completed the scheduled drug dosing regimen (108/108 doses) and planned assessments (60/60). While the placebo arm reported fewer overall non-serious AEs (65 vs 22), there were no serious adverse events related to D + Q.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"The Senolytic Drug Navitoclax Protects the Brain After Experimental Ischemic Stroke","year":2026,"doi":"10.3390/ph19030431","url":"https://doi.org/10.3390/ph19030431","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"primary","cited_as":"Falahatgaroshibi 2026","excerpt":"Background/Objectives : Senescence has been recently described in brain cells following ischemic stroke. The potential of targeting senescence as an effective therapeutic approach in the treatment of ischemic stroke requires further investigation. This study evaluated the effects of the senolytic drug navitoclax after experimental ischemic stroke. Methods : Navitoclax was injected into male young Wistar rats at doses of 10 and 30 mg/kg (i.p.). to evaluate its pharmacokinetics, cerebral levels and potential to cause thrombocytopenia.

Methods : Navitoclax was injected into male young Wistar rats at doses of 10 and 30 mg/kg (i.p.). to evaluate its pharmacokinetics, cerebral levels and potential to cause thrombocytopenia. Subsequently, a second group of rats underwent 60 min of transient middle cerebral artery occlusion (tMCAO). Navitoclax (10 mg/kg, i.p.) or vehicle was injected every other day between days 3 and 13 after tMCAO. Neurofunctional performance, infarct size, and senescence markers were assessed on day 14. Results : Navitoclax (10 mg/kg) administration resulted in a maximum plasma concentration of 0.702 mg/L and half-life of 11.33 h. Additionally, a brain concentration of 0.04 ± 0.02 µg/g was detected.

Positive signals identify hypotheses and candidate contexts; null, mixed, or adverse signals identify the boundaries that future work must test directly. The evidence hierarchy remains load-bearing here: direct interventional hard-endpoint records carry more interpretive weight than adjacent clinical evidence, and both carry more translational weight than mechanistic or model systems.

This process alleviates chondrocyte senescence and facilitates the phenotypic shift of pro-inflammatory M1 macrophages toward an anti-inflammatory M2 state. Additionally, surface conjugation with an anti-DPP4 antibody enables BS@MD to selectively target sCDs and disassemble in the acidic lysosomal environment, releasing bortezomib (BTZ) and sabutoclax (Sab)."},{"id":"source_14","type":"source","study":"Senolytics alleviate cyclophosphamide-induced premature ovarian insufficiency by eliminating senescent cells","year":2026,"doi":"10.4081/ejh.2026.4537","url":"https://doi.org/10.4081/ejh.2026.4537","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"primary","cited_as":"Su 2026","excerpt":"Alkylating agents, particularly cyclophosphamide (CY), are known for their high toxicity, which can lead to iatrogenic premature ovarian insufficiency (POI) and infertility in young cancer survivors.

Given that chemotherapy induces cellular senescence, we investigated the therapeutic potential of dasatinib (D) and quercetin (Q), a senolytic combination known to eliminate senescent cells. Using a CY-induced murine model of ovarian injury, we found that CY treatment increased the accumulation of senescent cells in the ovaries. The resulting senescence-associated secretory phenotype (SASP) led to a deterioration of the ovarian microenvironment, characterized by increased follicular atresia and a decline in follicle quantity, ultimately culminating in POI. Our findings demonstrate that DQ therapy effectively mitigated CY-induced damage by clearing senescent cells and reducing SASP secretion.

The evidence profile contains 1 direct clinical source, 26 adjacent clinical sources, and 6 mechanistic or model-system sources, with 46 cross-study disagreements across the evidence base. Positive study-level signals are summarized in the immune and inflammation, longevity, contextual adjacent evidence outcome classes, null signals in the contextual adjacent evidence, mechanism, immune and inflammation outcome classes, and negative signals in no dominant outcome class. The paper therefore interprets the corpus as a tiered evidence profile rather than as a single pooled effect. The conclusion is that ABT-263 remains a bounded geroscience case: the retained clinical and mechanistic evidence profile defines the scope for targeted testing, while mixed and null findings limit any unqualified anti-aging claim.","The conclusion is that ABT-263 remains a bounded geroscience case: the retained clinical and mechanistic evidence profile defines the scope for targeted testing, while mixed and null findings limit any unqualified anti-aging claim.","Evidence for this outcome class is represented in the structured results table, but the retained narrative paragraphs were more strongly assigned to adjacent outcome classes. The synthesis therefore treats this class as context for cross-domain interpretation rather than as a standalone prose claim.","3 included sources were assigned to this outcome class. Directional coding: mixed=1, null=2. Directness coding: direct=1, indirect=2.","Several outcome classes rest on a single source, and that single-source status is itself a within-corpus generalization risk that should be foregrounded. The directness asymmetry is also informative: Farr 2024 is the only source coded direct, while the surrounding directness=indirect and directness=mechanistic sources share no common endpoint definition, so a corroborating indirect signal cannot substitute for a missing direct one.","Finally, the mechanism-to-clinic gap is itself a corpus-level limitation that no individual RoB column can encode. The result is a corpus in which a coherent mechanistic story is told, but the clinically relevant dose, schedule, target population, and hard outcome remain undefined, and any cross-domain inference from mechanistic or surrogate sources onto a clinical recommendation must be treated as hypothesis-generating rather than evidence-supported.","For ABT-263, the final interpretation is deliberately tiered: the retained clinical and mechanistic evidence profile defines a bounded geroscience rationale, but the corpus does not support treating mechanistic target engagement, intermediate biomarkers, and patient-relevant outcomes as interchangeable evidence. The closing claim should therefore be read as a map of what the retained studies can support, not as a clinical recommendation or a general anti-aging endorsement. Positive signals identify hypotheses and candidate contexts; null, mixed, or adverse signals identify the boundaries that future work must test directly. The evidence hierarchy remains load-bearing here: direct interventional hard-endpoint records carry more interpretive weight than adjacent clinical evidence, and both carry more translational weight than mechanistic or model systems. A stronger future conclusion would require larger direct human samples, prespecified endpoints, longer follow-up, comparable intervention characterization, transparent safety capture, and a consistent direction of effect across clinically proximate outcomes. Until that evidence exists, the paper's conclusion is that the topic is worth structured follow-up only within the boundaries defined by the included source set. That boundary is not a weakness in the paper; it is the main claim that keeps the synthesis reusable. Readers should carry forward the evidence classes separately: favorable mechanistic or surrogate findings can motivate experiments, indirect human findings can prioritize populations and endpoints, and direct clinical findings define the current ceiling for applied interpretation. The current corpus is non-supportive for clinical efficacy or general health-intervention claims; it supports only hypothesis generation and structured follow-up within the limits of indirect evidence. Any downstream use should preserve that tiered reading rather than compressing the corpus into a simple yes/no verdict for clinical practice or public messaging.","Across 33 curated reference papers, the evidence base for senolytics shows a context-dependent profile. Positive signals appear in: immune inflammation, longevity. Null findings dominate: contextual other, mechanism. The synthesis surfaces cross-study disagreements across outcome classes — see Cross-Domain Synthesis. The senolytics anti-aging case as currently constituted is incomplete: mechanistic plausibility coexists with mixed or sparse human-RCT evidence, and the boundary conditions remain to be established."]}},{"name":"evidence_table.csv","media_type":"text/csv","content":"study,population,intervention_or_exposure,comparator,endpoint,effect,risk_of_bias,directness\r\n\"Senolytics dasatinib and quercetin in idiopathic pulmonary fibrosis: results of a phase I, single-blind, single-center, randomized, placebo-controlled pilot trial on feasibility and tolerability\",not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\nThe Senolytic Drug Navitoclax Protects the Brain After Experimental Ischemic Stroke,not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\nSenolytic reduction of senescent cells mitigates atrial arrhythmia vulnerability in aging rabbits,not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\nSenolytic Treatment With Fisetin Reverses Age‐Related Endothelial Dysfunction Partially Mediated by SASP Factor CXCL12,not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\n\"Senolytic drugs, dasatinib and quercetin, attenuate adipose tissue inflammation, and ameliorate metabolic function in old age\",not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\nSenolytic-loaded asymmetric wound dressing for targeted senescent cell clearance in diabetic wound healing,not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\nComparative analysis of senolytic drugs reveals mitochondrial determinants of efficacy and resistance,not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\nSupramolecular delivery of senolytics enables targeted anti-senescence therapy and accelerated fracture healing,not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\nReevaluating the senolytic activity of a GLS1 inhibitor and an anti-PD-1 antibody: toward greater reproducibility and methodological rigor,not extracted,not extracted,not extracted,not extracted,not extracted,not appraised in public sidecar,primary\r\nIs exercise a senolytic medicine?
