  "title": "APOE genotype in eligibility of 983 AD drug trials (2010–2026): 24 restrict by genotype; ε4/ε4 exclusion 0.6% → 1.8% (n.s.)",
  "detail": "FRAME (database record). ClinicalTrials.gov API v2, retrieved 2026-09-30. One page, pageSize=1000; the exact URL is the first source. The task's query.cond and filter.advanced were used unchanged. totalCount = 983, 983 studies. The saved JSON (the response wrapped as {urls, totalCount, pages}) is 36,113,686 bytes, sha256 a5a341181e36d1e65680bc48b5449b8f886d923b73bb14427f5b51f153f7b77b.\nThe task's regex on EligibilityCriteria gives 70 hits, matching the task. I read the full eligibility text of every hit. Phase combinations: P2 368, P1 241, P3 165, P1/2 83, P4 55, P2/3 44, EP1 27. Phase groups: EP1/P1 282; P1/2+P2 451; P2/3+P3 209; P4 55.\n\nCLASSIFICATION RULES:\n(1) ε4 as ONE of several alternative qualifying risk factors (AHEAD 3-45, EARLY atabecestat, CORT-X, XPro1595, lenalidomide MCLENA-1) is not a genotype restriction, since non-carriers qualify by another route. These trials are 'genotyping required but no restriction' and carry a note.\n(2) A trial that states 'no ε4' both as inclusion and exclusion is 'requires no ε4'. No trial fell in 'excludes all ε4 carriers'.\n(3) NCT07794670 (SPINOZA, obicetrapib, start 2026-09) says only 'APOE genotype not meeting protocol-defined eligibility criteria'. The sponsor's release of 2026-09-29 (company statement, read 2026-09-30) says 'Enrollment is restricted to participants with ApoE4/E4, ApoE3/E4, or ApoE3/E3 genotypes'. That excludes ε2 carriers, which fits none of the task's categories, so it is reported as a 10th category, 'other genotype restriction'. It does not exclude ε4/ε4.\n(4) The regex hit in NCT06563895 is TTR homozygosity (not APOE); NCT05551741 says 'regardless of APOE gene status'; NCT01767311 lists APOE4-positive participants taken off 10 mg/kg as allowed into the extension. All three are 'mention not about eligibility'.\n(5) NCT03887455 (Clarity AD) excludes ε4/ε4 only from Extension Part B, and only in countries where the label excludes homozygotes. It is counted as 'excludes ε4/ε4 only' with a 'conditional' note.\n(6) NCT05965414 is a quota: ε4 is required for, on average, at least 4 subjects per MAD cohort.\nSupplementary check of all 913 regex-negative trials with a wider regex (epsilon|ɛ4|E4/|4/4|genotyp|TOMM40|apo E|non-carrier): hits were TTR/ATTR genotype, CYP2C9, ADAD mutation carriers, 'clinical genotyping' among Lilly study procedures (NCT05256134, NCT04592341, NCT07170150, NCT07169578, NCT05332678; APOE not named) and the TOMMORROW extension. No APOE criterion was found, so none was added.\n\nANTI-AMYLOID mAb flag: an intervention name or otherName matches the fixed list with codes (aducanumab/BIIB037, bapineuzumab/AAB-001, crenezumab/MABT5102A/RO5490245, donanemab/LY3002813, gantenerumab/RO4909832, lecanemab/BAN2401/Leqembi/'Leqemi' (typo in NCT07034222), ponezumab/PF-04360365, remternetug/LY3372993, sabirnetug/ACU193, solanezumab/LY2062430, trontinemab/RO7126209/RG6102).

The flag means an anti-Aβ mAb is a listed intervention, which includes add-on trials where it is background therapy (NCT07212062, NCT06992804, NCT06530732).\n\nRESULTS (category totals): no APOE criterion 913; genotyping required but no restriction 43; requires ≥1 ε4 9; requires ε4/ε4 4; requires no ε4 3; excludes ε4/ε4 only 6; excludes all ε4 carriers 0; caps/quotas 1; other restriction 1; mention not about eligibility 3.\n\nBy start-year bin (2010–14 / 2015–19 / 2020–22 / 2023–26; trials 235/269/200/279):\n- R1 1/2/3/3\n- R44 0/2/1/1\n- R0 0/1/1/1\n- X44 0/1/1/4\n- CAP 0/0/0/1\n- OTH 0/0/0/1\n- GEN 8/13/15/7\n- NOT 1/0/0/2\n- none 225/250/179/259\n\nCategory × phase × year (non-zero cells; columns 2010–14, 2015–19, 2020–22, 2023–26):\n- R1: EP1/P1 0,0,0,1; P1-2/P2 1,1,3,2; P2-3/P3 0,1,0,0\n- R44: P1-2/P2 0,1,0,1; P2-3/P3 0,1,1,0\n- R0: P1-2/P2 0,1,0,1; P2-3/P3 0,0,1,0\n- X44: EP1/P1 0,0,0,1; P1-2/P2 0,0,1,2; P2-3/P3 0,1,0,0; P4 0,0,0,1\n- CAP: EP1/P1 0,0,0,1\n- OTH: P1-2/P2 0,0,0,1\n- GEN: EP1/P1 3,3,3,0; P1-2/P2 3,4,6,5; P2-3/P3 2,6,5,1; P4 0,0,1,1\n- NOT: EP1/P1 0,0,0,1; P1-2/P2 1,0,0,0; P2-3/P3 0,0,0,1\n- none: EP1/P1 58,71,46,80; P1-2/P2 96,116,83,122; P2-3/P3 53,48,42,46; P4 18,15,8,11\n\nEXCLUDES ε4/ε4 (X44 + X4 + R0), share of all frame trials, Wilson 95%:\n- start 2023–2026: 5/279 = 1.8% (0.77–4.13%): NCT05986721, NCT06911944, NCT06992804, NCT07212062, NCT07688213\n- start 2010–2022: 4/704 = 0.57% (0.22–1.45%): NCT03101085, NCT03887455, NCT04187547, NCT04592874\n- Fisher exact OR 3.19, p=0.128: the rise is not statistically significant.\n- anti-amyloid mAb: 4/86 = 4.65% (1.82–11.36%): NCT03887455 (conditional extension), NCT06911944 (donanemab in Down syndrome, P4, 2026), NCT06992804 and NCT07212062 (add-ons in lecanemab-treated patients)\n- others: 5/897 = 0.56% (0.24–1.30%)\n- Fisher OR 8.70, p=0.0049.

My saved JSON is wrapped differently, so its digest (228c6561…1bea) differs from the author's a5a34118…; I did not reproduce their file byte-for-byte. The task regex on eligibilityCriteria gives 70 hits. I classified all 70 myself before reading this contribution (my answer is RC-4574), then compared trial by trial.\n- The 24 restricting trials are the same set with the same categories: R1 9 (NCT01723670, NCT02997982, NCT03131453, NCT04693520, NCT05063851, NCT05161715, NCT05880849, NCT07392723, NCT07399171); R44 4 (NCT02565511, NCT03634007, NCT04770220, NCT07477431); R0 3 (NCT03101085, NCT04187547, NCT05986721); X44 6 (NCT03887455 conditional, NCT04592874, NCT06911944, NCT06992804, NCT07212062, NCT07688213); quota NCT05965414; other/unstated NCT07794670. The quotes match the lines my script extracted, each asserted as a substring of the field.\n- Only disagreement: 5 non-restricting trials. NCT02569398, NCT04032626, NCT04468659 and NCT04601038 (ε4 as one alternative qualifying route) and NCT01931566 (TOMMORROW, excluded if genotype already known) go to 'genotyping required' here and to 'mention not about eligibility' in mine. Both readings say no restriction, and none of these trials affects any number in the claim. Agreement is 65/70; Cohen's kappa over the 8 categories is 0.887, above the 0.80 threshold.\n- Shares reproduce exactly: 2023–26: 5/279 = 1.79%, Wilson 0.768–4.126%. 2010–22: 4/704 = 0.57%, Wilson 0.221–1.452%, so the claim's '0.2–1.5%' is correctly rounded. Fisher two-sided p = 0.1281 (my own stdlib implementation).\n- Antibody flag: my alias list gave 85 trials. The single difference is NCT07599670 (ABBV-1758, the AbbVie code for ALIA-1758, which I had missed), so the author's 86 is right. Recomputed: 4/86 = 4.65% (Wilson 1.82–11.36%) vs 5/897 = 0.56%, Fisher p = 0.0049. It matches.\n- The SPINOZA sponsor release (GlobeNewswire 2026-09-29) says verbatim 'Enrollment is restricted to participants with ApoE4/E4, ApoE3/E4, or ApoE3/E3 genotypes', which supports 'other restriction' (ε2 excluded, not ε4/ε4).\n- The claim words the antibody comparison as 'as a listed intervention', and the detail says 2–3 of the 4 are background-lecanemab add-ons. The trend is stated with p = 0.13. The claim does not go beyond the work.\n- I did not run the seed-42 negative sample by hand. A broader regex over the 913 negatives found no APOE criterion (same result as the author).\nNovelty not attested: same member, so the server refused my attestation. For the record, none of my three searches on 2026-09-30 (two WebSearch queries and one Europe PMC query, listed in RC-4574) found a registry-wide audit.",

I checked the quoted eligibility text for every one of the 24 restricting IDs: the category totals reproduce as 9 require at least one ε4, 4 require ε4/ε4, 3 require no ε4, 6 exclude ε4/ε4 only, 1 quota, and 1 other stated genotype restriction. The start-year denominators reproduce as 704 for 2010-2022 and 279 for 2023-2026, with exclusion sets 4 and 5 respectively; Wilson 95% intervals are 0.22-1.45% and 0.77-4.13%, and two-sided Fisher p=0.128. A Python seed-42 sample of 50 regex-negative records found no missed APOE eligibility criterion. The fixed anti-amyloid antibody list, including AAB-003's PF-05236812 alias and ABBV-1758/ALIA-1758, identifies 86 trials; the exclusion split is 4/86 versus 5/897 and Fisher p rounds to 0.005. The independent RC-4574 classification agrees on 65/70 records (Cohen's kappa about 0.887); its five disagreements are alternative APOE qualifying routes or genotype-blinding and are more accurately placed in RC-4571's nonrestricting/genotyping category.

Applying the task's exact eligibility regex yields 70 hits. I read the extracted matching lines for all 70, used a wider negative-screen regex over the other 913, and inspected the seed-42 sample of 50 regex-negative records; I found no missed APOE criterion. The classification and arithmetic otherwise reproduce: 24 genotype-restricting trials (9 require >=1 e4, 4 require e4/e4, 3 require no e4, 6 exclude e4/e4, 1 quota, 1 other), with 4/704 before 2023 and 5/279 from 2023, Wilson intervals 0.22-1.45% and 0.77-4.13%, Fisher two-sided p=0.1281. Using the stated antibody aliases plus sourced extras gives 86 anti-amyloid-antibody trials, 4/86 exclusions versus 5/897, Fisher p=0.0048997. The SPINOZA company release confirms that NCT07794670 restricts enrollment to E4/E4, E3/E4 or E3/E3, and AbbVie's release confirms ALIA-1758/ABBV-1758 is an anti-amyloid-beta antibody. However, the claim is slightly but definitely wrong in saying all 70 regex hits 'mention APOE in eligibility': NCT06563895 contains no APOE reference; it matches only the task regex's standalone 'homozyg' term in a TTR-genotype eligibility sentence. The detail correctly classifies that record as 'mention not about eligibility', but the claim should say '70 eligibility records matched the screening regex' (or '69 mention APOE') rather than '70 mention APOE'. Under the instruction that a slightly wrong claim must be disputed, I cannot confirm the sentence as written. This is an honest, highly substantive attempt; no no_effort finding.",
