# Build brief: merged Dupixent (dupilumab) in atopic dermatitis — public evidence dossier

Written 2026-10-16; revised the same day three times: first to add the citation standard, then to fold in a third draft built from structured records (openFDA, Drugs@FDA, ClinicalTrials.gov, PubMed via Pipeworx), then (this revision) to add section 8, the punch list from a fourth build that followed this brief end to end on 2026-10-16 and the tooling results it produced. Purpose: produce one dossier from the drafts, keeping the stronger parts of each, fixing known errors, and raising the visual standard. Intended for a payer, HTA or guideline reader. Not medical advice; every figure must trace to a primary source.

## 0. The three drafts and what each contributes

- **Draft A (14 pp, wide-scope)** — contributes the age-cohort efficacy table (adults to 6 months), the six-agent competitor table with each agent's own pivotal EASI-75, LEVEL UP results, the Chu 2023 and Silverberg 2021 NMA rankings, NICE TA534 and CADTH decisions, US list-price history, the pCPA agreement, and the 12-month watch list. Weakness: several figures "as recalled"; three dated errors (section 2).
- **Draft B (9 pp, primary-source)** — contributes the openFDA label table with pregnancy and warnings, Regeneron 10-Q litigation and H1 2026 sales, the FAERS snapshot with caveats, the CTCL section with JEADV 2026 consensus, JADE COMPARE/DARE as head-to-head trials, the SOLO rescue-imputation note, and the "how this was built" section. Weakness: stale on rocatinlimab; no LEVEL UP.
- **Draft C (16 pp, structured-record audit)** — contributes the provenance format (every figure to a tool call, record ID and timestamp), the full SOLO 1 registry table with CIs and p-values, the label Warnings & Precautions table by section number, the eleven-trial program table with NCT numbers, Heads Up and JADE COMPARE in full, competitor label set IDs and upadacitinib ANDA status, Australia/Singapore/NIHR economics with PMIDs, and the API-pitfall notes. Weakness: no CTCL, no pediatric numbers, no nemolizumab, no US economics or sales; one wrong headline claim (section 2).
- **Draft D (fourth pass, 2026-10-16, built from this brief)** — delivered as a Claude Doc with all 13 sections; its gaps are itemised in section 8 and are the release blockers.

**Backbone assignment**: Draft C's provenance format, label tables, SOLO 1 table, head-to-head section and data-quality notes form the skeleton. Draft B fills CTCL, litigation, sales and FAERS. Draft A fills pediatrics, competitor pivotal figures, LEVEL UP, NMAs, US/UK/Canada HTA, pricing, pipeline and watch list. Draft C's own "not pulled" list is the to-do list for the merge.

## 1. Source hierarchy (apply in this order)

1. **Current US label** via DailyMed SPL (set ID 595f437d-2729-40bb-9c62-c8ece1f82780) and the openFDA `drug/label` record (effective 2026-04-22; Drugs@FDA shows a later labeling supplement S-076 dated 2026-07-15, so check DailyMed for a newer version before citing). Query by brand name (`openfda.brand_name:DUPIXENT`), not generic name (see section 7).
2. **Registry results**: ClinicalTrials.gov v2 posted results for NCT02277743 (SOLO 1), NCT02277769 (SOLO 2), NCT02260986 (CHRONOS), NCT03054428 (AD-1526), NCT03345914 (AD-1652), NCT03346434 (PRESCHOOL/AD-1539), NCT04417894 (HAFT), NCT01949311 (AD-1225 OLE), NCT02395133 (SOLO-CONTINUE), NCT02755649 (CAFE). Prefer registry decimals over rounded secondary summaries. Registry results are sponsor-posted, not FDA conclusions; say so once.
3. **SEC filings**: Regeneron 10-Q filed 2026-07-30 (accession 0000872589-26-000025) for litigation and H1 2026 sales; Sanofi annual reports for 2018–2024 euro sales. No "as recalled" sales figures.
4. **Peer-reviewed primaries**: NEJM 2016 (SOLO), Lancet 2017 (CHRONOS), JAMA Dermatol 2021 (Heads Up), NEJM 2021 (JADE COMPARE), Lancet 2022 (JADE DARE, PRESCHOOL), LEVEL UP, Chu et al. JACI 2023 NMA, JEADV 2026 CTCL consensus, J Dermatolog Treat 2026 Heads Up benefit-risk reanalysis.
5. **HTA documents**: ICER 2017 final report and the separate Zimmermann JDD 2018 paper (two rows, two ICERs), ICER 2021 JAK/tralokinumab review, NICE TA534, NIHR HTA 2024 (Edwards et al.), CADTH/CDA-AMC pediatric recommendation and adult pharmacoeconomic report, Australia (Li 2025) and Singapore (Ong 2024) cost-utility papers.
6. **Trade press** only for conference abstracts not yet published; label each such figure "conference abstract, unpublished".
7. **Law-firm pages**: dates only, cross-checked against the JPML order or the 10-Q. Never cited for medical claims.

## 2. Corrections that must be applied

- The hand-and-foot (LIBERTY-AD-HAFT, NCT04417894, primary completion Aug 2022) US label update was announced January 2024, with EU alignment at the same time. It is not an October 2026 event. Remove from "new in 2026" framing and the watch list.
- The current US prescribing information was revised April 2026, not January 2026.
- Direct head-to-head trials against dupilumab are four, not two: Heads Up (NCT03738397, upadacitinib 30 mg, AbbVie, n=673 randomised: 331 dupilumab, 342 upadacitinib), LEVEL UP (NCT05601882, upadacitinib 15→30 mg, open-label, AbbVie, n≈920), JADE COMPARE (NCT03720470, abrocitinib, Pfizer, n=838), JADE DARE (NCT04345367, abrocitinib, Pfizer, n=727).
- Rocatinlimab: Kyowa Kirin discontinued all trials on 2026-03-03 after a safety review (Kaposi's sarcoma cases). Not "in phase 3". Amlitelimab (Sanofi, OX40L) remains the live OX40-axis candidate.
- ICER 2021 was a comparative review of JAK inhibitors and tralokinumab with dupilumab as anchor; it did not "re-affirm" dupilumab's own cost-effectiveness.
- Dupixent is **not** "the only approved advanced systemic for AD without a boxed warning". Tralokinumab (Adbry), lebrikizumab (Ebglyss) and nemolizumab (Nemluvio) also carry no boxed warning and are also positioned after topicals. The defensible distinctions are: the only one approved from 6 months of age; the broadest set of co-morbid indications; the longest post-marketing exposure.
- SOLO 1 secondary endpoints: do not write "all ranked secondary endpoints were significant". The hierarchical testing sequence broke at the skin-infection endpoint, so later secondaries are nominal. State both facts.
- PRESCHOOL (AD-1539) n: 202 enrolled (including the part A PK cohort) versus 162 randomized in part B. Give the randomized n in the efficacy table and footnote enrollment.
- Nemolizumab (Nemluvio, FDA-approved for AD December 2024, ≥12 y with TCS) must appear in the competitor table.
- CTCL: FDA's quarterly potential-signals listing became public in March 2025 (covering Oct–Dec 2024 FAERS); plaintiffs cite a 15 January 2025 notification. Give both with provenance. MDL No. 3180, D.N.J., Judge Zahid N. Quraishi, created 2026-06-04, 15 actions initially. The April 2026 label contains no lymphoma warning.
- All five approved competitors (tralokinumab, lebrikizumab, nemolizumab, upadacitinib, abrocitinib) have a US AD age floor of 12 years; do not write 18 for abrocitinib.
- Any figure previously marked "recalled", "approximate", "from snippet" or "not pulled" is re-pulled from the primary before it appears, or dropped.

## 3. Citation standard

**Every number, date and regulatory statement carries an inline citation.** No uncited sentence of fact may appear anywhere, including the executive summary, tables, figure captions and the watch list.

- **Inline form**: square-bracket numerals in order of first appearance, `[12]`, after the figure they support, before the period. Tables get a `Source` column holding the same numerals. Figure captions end with `Source: [n]`.
- **Provenance tag**: each inline citation is suffixed with its tier letter: `[12-L]` label, `[12-R]` registry, `[12-P]` peer-reviewed primary, `[12-H]` HTA document, `[12-S]` SEC or company filing, `[12-C]` conference abstract, `[12-T]` trade press, `[12-W]` law-firm or other secondary web page (dates only). Legend on page 1.
- **Full reference entry** (Vancouver-style, one per numeral): authors or organisation; title; journal/publisher; year; volume(issue):pages; persistent identifier (DOI or PMID, NCT number, SPL set ID, SEC accession number, NICE/CADTH ID); URL; date accessed. An entry without a persistent identifier or resolvable URL is not permitted.
- **Trial figures**: cite registry and primary publication together, e.g. `[3-R, 4-P]`. If they disagree, use the registry figure and footnote the publication value.
- **Competitor pivotal figures**: cite each competitor's own primary publication; never an NMA or review for a single-trial number.
- **Secondary-source handling**: trade-press summaries of unpublished conference data are `[n-C]` with congress, year and abstract number. A trade-press citation standing in for a published paper is a defect.
- **Label citations** name the section, e.g. `[1-L §5.2]` conjunctivitis/keratitis, `[1-L §6.1]` adverse-reaction tables, `[1-L §14]` clinical studies.
- **Prices**: cite the manufacturer price page with exact access date; keep a dated archive copy. Annualise explicitly: one carton = 2 injections = one month at Q2W, so annual list = carton price × 12 (2026-01-02: $4,193.03 × 12 = $50,316). Show the multiplication once.
- **Litigation**: cite the JPML transfer order and Regeneron's 10-Q; law-firm pages only as `[n-W]` for a date not otherwise obtainable.
- **Economics**: cite the HTA body's own document rather than press coverage.
- **Tool-call provenance** (from Draft C): in the "how this was built" section, list every structured record pulled as pack/tool, record identifier, and observation timestamp. This is in addition to, not instead of, the numbered references.

### Seed reference list

Identifiers marked "confirm" are to be checked at build; "locate" means no stable identifier was available when this brief was written. PMIDs for 8, 10, 14, 19, 31–34 come from Draft C's PubMed pulls on 2026-10-16.

## 4. Document structure (target 14–16 pages)

1. **Masthead and key-data rail** (from Draft C) — product, mechanism, BLA, approval dates, current label set ID and date, indications, AD dosing, boxed warning (none), recalls (none), trial count, then a five-cell "at a glance" strip: age floor, week-16 EASI-75, boxed warning, list price, 2025 global sales. Every cell cited.
2. **Executive summary** — three tensions (efficacy durable but not the ceiling; safety the core argument with CTCL open; economics favourable on QALY but price-sensitive). Five bullet facts, each cited.
3. **Label and regulatory history** — label table (dosing by age, nine indications, warnings by section number 5.1–5.10, contraindication, pregnancy registry); approval timeline (adults 2017-03, adolescents 2019-03, 6–11 y 2020-05, ≥6 mo 2022-06, HAFT data added 2024-01); the 2023 CSU complete response letter as a one-line caution.
4. **Pivotal efficacy** — (a) SOLO 1 full registry table with CIs and p-values; (b) cross-cohort table (SOLO 2, CHRONOS wk 16 and 52, AD-1526, AD-1652, PRESCHOOL) with registry decimals; (c) eleven-trial program table with NCT, n, completion. Notes: rescue-as-nonresponse imputation; hierarchy break at skin infection; weekly dosing added nothing over Q2W.
5. **Long-term and real-world** — AD-1225 exposure counts from label §6.1; CHRONOS week 52; HAFT as a 2024 label addition; conference items flagged; international 52-week cohort with baseline-imbalance caveat.
6. **Safety** — label Table 9 with mono and +TCS arms; CHRONOS 52-week ocular and injection-site rates; pediatric OLE notes (HFMD, papilloma); ocular warning including post-marketing visual impairment; SOLO 1 serious-AE groups; FAERS top-15 with the "reports, not incidence; nine indications; patient-support-program filings" caveat; pregnancy.
7. **CTCL** — signal, regulatory, litigation, JEADV 2026 consensus (547 cases, 51 studies, mean age 58, 75% discontinued, 62% CTCL-directed treatment; the mean-onset and MF-share figures in earlier drafts must be re-read from the paper before reuse), EORTC 2026 consensus, unmasking hypothesis, biopsy guidance. Evidence-grade box.
8. **Competing treatments** — table of all six approved agents plus baricitinib ex-US: class/route, US AD age floor and label position, boxed warning, lab monitoring, generic/biosimilar status, own pivotal EASI-75 vs placebo, evidence vs dupilumab. Head-to-head subsection with all four trials (Heads Up and JADE COMPARE in full from Draft C; JADE DARE and LEVEL UP from publications). NMA subsection (Chu 2023, Silverberg 2021, NIHR 2024, lebrikizumab 2025). Payer positioning (DoD P&T). Pipeline (amlitelimab H2 2026 filing, Regeneron long-acting IL-13, zumilokibart, tilrekimig, orismilast, bosakitug, temtokibart; rocatinlimab terminated).
9. **Economics** — price table (2017 WAC, 2025/2026 list, Canadian submitted price); cost-effectiveness table with ICER 2017 and Zimmermann 2018 separate, ICER 2021, NICE TA534, NIHR 2024, CADTH pediatric, Australia 2025, Singapore 2024, Italy 2020/2023, Taiwan 2026, 2023 systematic review, ISPOR 2023/2024; "reading across" paragraph (QALY gaps ~0.04 over 5 years, price decides); pCPA letter of intent.
10. **Market and sales** — sourced bar chart 2018–2025 plus H1 2026 table from the 10-Q (US, ex-US, global, y/y, Regeneron profit share). Patent horizon only if confirmed against the Purple Book.
11. **Evidence gaps and watch list** — no biologic-vs-biologic RCT; OLE-based extrapolation; opaque net price; CTCL causality; pediatric economics; step-down evidence. Watch: FDA signal decision, MDL bellwethers, Sanofi Q3 2026 results (30 Oct), amlitelimab filing, Regeneron IL-13 readouts, LEVEL UP week-32.
12. **How this was built** — tool-call table (pack/tool, record ID, timestamp) per Draft C, plus data-quality notes and API pitfalls (section 7), plus anything still on a secondary source.
13. **References** — numbered list per section 3.

## 5. Design specification

- Page: A4 or US Letter, 20 mm margins, single column, running header with short title, footer with page x of y and build date.
- Type: one serif for body (Source Serif or Georgia) at 10.5/15, one sans for headings, tables and captions (Inter or Source Sans). Three heading levels.
- Colour: one accent (deep teal or navy) for headings, table header rows and the current-year bar; neutral greys elsewhere; red reserved for "unverified" tags. No gradients.
- Key-data rail: two-column table on page 1 with label cells in the sans face at 9 pt, value cells at 10 pt, 4% tint on alternate rows.
- Tables: full-width, 4% zebra tint, numeric columns right-aligned, units in the header, a Source column last. Header row repeats across page breaks. No table cell may read "not pulled" in the released version.
- Figures: sales bar chart with current year in accent and prior years in grey, value labels, one-line source caption. Dot-and-whisker efficacy plot (drug vs placebo per trial, with CIs where the registry gives them).
- Callouts: shaded "Evidence grade" box at the top of Safety, CTCL and Economics.
- Citation display: inline numerals in the accent colour, superscript tier letter; provenance legend on page 1; references set at 9/12 in the sans face.
- Executive summary on its own page.
- Delivery when no HTML artifact tool is available: a Claude Doc (one tab, pipe tables, sales chart drawn from rows) is an acceptable substitute; the design spec above then applies to the exported PDF.

## 6. QA checklist before release

- Every number, date and regulatory statement has an inline citation with a tier letter, and every reference entry has a persistent identifier and resolvable URL.
- No "recalled", "approximate", "from snippet" or "not pulled" figure remains.
- No trade-press citation stands in for a published paper.
- Executive-summary dates match the body (HAFT 2024, label April 2026, MDL June 2026, rocatinlimab March 2026).
- Head-to-head section names all four trials and sponsors; competitor table includes nemolizumab.
- No claim that Dupixent is the only advanced systemic without a boxed warning.
- SOLO 1 secondary endpoints are described with the hierarchy break.
- ICER 2017 and Zimmermann 2018 are separate rows.
- Sales chart and 10-Q table reconcile (Q2 2026 global $5,998M; H1 2026 $10,878M).
- Competitor pivotal figures are marked cross-trial, not head-to-head.
- Label version cited matches the newest DailyMed SPL, not the openFDA cache.
- Annual list price = carton price × 12, shown once; no divergent annual figures in different sections.
- Brand and trial names spell-checked (Nemluvio, Ebglyss, Adbry, Cibinqo, Rinvoq; SOLO, CHRONOS, Heads Up, LEVEL UP, JADE DARE).

## 7. API and tooling pitfalls observed (Draft C, 2026-10-16; confirmed and extended by Draft D the same day)

- openFDA `drug/label` can lag DailyMed by about two versions and two months for the same set ID; cite the DailyMed version date.
- openFDA label fields were truncated at roughly 4,000 characters per section in the tool used; the AD adverse-reaction table was cut after the conjunctivitis row, and §5.4/§5.6 were not returned at highlights level. Fetch the SPL directly for full tables.
- A generic-name label query ("dupilumab") returned the Cibinqo (abrocitinib) label first; use `openfda.brand_name:DUPIXENT`.
- ClinicalTrials.gov intervention strings mix dose arms, placebos and outcome instruments; normalize competitor tables by hand.
- Registry results are sponsor-submitted; state this once and note where hierarchical testing broke.
- FAERS counts are reports, not patients; compare within-drug rank order only, never across drugs. Ten of the top 15 Dupixent terms are symptom, administration-error or lack-of-effect terms.
- Multi-PMID abstract requests through the aggregator were mis-routed to finance tools; single-PMID requests phrased "get the full abstract text of PubMed ID N" routed correctly.
- **Pipeworx `ask_pipeworx_grounded` on ClinicalTrials.gov (Draft D)**: of five single-NCT registry questions, two returned the full record (NCT02277743 SOLO 1, NCT03738397 Heads Up with `prefer_tool: ct_get_study`) and three were routed to `equity-finance` or `no_tool_match` even with `prefer_tool` pinned (NCT03720470, NCT02260986, NCT03346434). Phrasing that worked: "For ClinicalTrials.gov study NCT…, what are the posted primary outcome results…". When the router misroutes, do not retry more than once; take the figure from the primary publication and mark the row `[n-P]` only.
- **Pipeworx grounded on SEC 10-Q and on the openFDA label with a long question**: timed out ("operation was aborted due to timeout"). A short, single-field label question ("effective_time and warnings headings") succeeded. Pull the 10-Q via web search to the sec.gov filing index and `web_fetch` the document instead.
- Pipeworx `deep_research` was not used in Draft D on the strength of the earlier TSLA finding (zero findings on a multi-part question); nothing here contradicts that.
- Sponsorship runs both ways: the head-to-head trials are AbbVie/Pfizer-sponsored; the 2026 Heads Up reanalysis has Sanofi-affiliated authors.
- Draft C cites a NoHumans procedure record for a single-artifact research-report format (obj_01M52X7Q1V27A211EVPYJY0VD9); read it before adopting the masthead/key-data-rail layout, and confirm it is still current.

## 8. Fourth-pass punch list (Draft D, 2026-10-16) — what makes it releasable

Draft D filled all 13 sections with citations but left these holes. Each item names the source to pull and where the figure lands.

**Fill the tables from A and C**
1. SOLO 2 (NCT02277769): registry week-16 IGA 0/1 and EASI-75 with CIs → cross-cohort table, row 2.
2. AD-1526 (NCT03054428) and AD-1652 (NCT03345914): registry week-16 IGA 0/1 and EASI-75 → cross-cohort table; Draft D left these as "reported in label §14", which fails the no-"not pulled" rule.
3. LEVEL UP (NCT05601882): week-16 primary from the publication or the congress abstract (congress, year, abstract number) → head-to-head table, row 4.
4. JADE DARE (NCT04345367): week-2 itch and week-4/16 EASI-90 primaries from Reich 2022 → head-to-head table, row 3.
5. Competitor pivotal week-16 EASI-75 vs placebo for ECZTRA 1/2, ADvocate 1/2, ARCADIA 1/2, Measure Up 1/2, JADE MONO-1/2, BREEZE-AD, each from its own paper with DOI → competitor table column 6.
6. Australia (Li 2025, PMID 40036347) and Singapore (Ong 2024, PMID 39003392) ICERs and thresholds → cost-effectiveness table; Taiwan (Yang 2026) if the abstract is readable.
7. CADTH 6 mo–11 y recommendation and the pCPA letter of intent (2026-10-15) → economics "reading across" and watch list.

**Pull the two primary documents directly**
8. Regeneron 10-Q, accession 0000872589-26-000025: H1 2026 Dupixent US / ex-US / global, Regeneron profit share, and the Dupixent products-liability note → market table and CTCL timeline; replaces press-release and law-firm sourcing for both.
9. JPML transfer order, MDL No. 3180 (2026-06-04): order date, number of actions, judge, and the open question on non-CTCL T-cell lymphomas → CTCL timeline rows 2 and 5; retire references 10 and 22 to `[n-W]` or drop them.

**Fix arithmetic and citations**
10. Price: state the annualisation once as $4,193.03 × 12 = $50,316 (Q2W, carton = 2 injections = 1 month) and use that figure everywhere; delete any rounded or divergent annual value.
11. Four mis-citations flagged by the reviewer. Candidates visible in Draft D, to be confirmed against the reviewer's list: (a) the 2017-03-28 approval date cited to a trade page rather than Drugs@FDA; (b) CHRONOS week-52 arm figures cited to Dermatology Times/Drug Discovery Trends rather than the Lancet paper; (c) the French CTCL consensus statistics partly cited through an AJMC summary rather than the paper; (d) PRESCHOOL figures confirmed through Carenet/thelimbic rather than the Lancet DOI. Each resolves by fetching the primary and re-pointing the numeral.
12. Add the Heads Up footnote under the head-to-head table: AbbVie-sponsored, double-dummy, upadacitinib 30 mg (the higher of two approved doses) vs dupilumab 300 mg Q2W, NRI-C imputation for COVID-19 missingness, 24-week blinded period; SAEs 14/342 vs 7/331 and one death on upadacitinib; conjunctivitis 35/331 vs 5/342 and acne 11/331 vs 64/342 (registry adverse-event module).

**Then**
13. Re-run the section 6 QA checklist; a dossier that passes it with items 1–12 closed is releasable.
