NCCN lists sunvozertinib as a first-line option in EGFR exon 20 insertion NSCLC
FF-001 Registered This is the whole record. It was written down before anyone knew the answer, and it has not been touched since.
Guideline listing (NCCN, ESMO): offered on judgment, not a track record — calibration not yet demonstrated.
The proposition
What was claimed
A version of the NCCN Clinical Practice Guidelines in Oncology for Non-Small Cell Lung Cancer carrying a version date on or before 2027-07-31 lists sunvozertinib (ZEGFROVY) as a first-line / initial systemic therapy option, at any NCCN category, for EGFR exon 20 insertion mutation-positive metastatic non-squamous NSCLC.

The estimate
The number, and what it has to beat
A number on its own is unfalsifiable. These are the alternatives it was registered against, each with the reasoning that produced it, frozen at the same cutoff.
Reference class: agents with a positive randomized phase 3 in a molecularly defined NSCLC subset appearing in an NCCN NSCLC line-of-therapy recommendation within 12 months of publication. Recent precedent in this guideline (alectinib adjuvant post-ALINA, amivantamab first-line post-PAPILLON, sevabertinib in ERBB2) is consistently fast. Estimate from precedent, not an enumerated count — the enumerated corpus is the object of the external-transition-forecast-v1 study and does not yet exist. Recorded as the honest state of this baseline at the cutoff.
A model that knows only NCCN's revision cadence. The NSCLC guideline is revised several times a year, so the probability that at least one revision opportunity falls inside a 12-month window is approximately 1.0. Having no evidence input, such a model cannot discriminate between pending candidates and defaults to the unconditional per-candidate incorporation rate, which is well below the phase-3-conditioned rate above. The output is the product of opportunity and that unconditional rate, recorded as the model's value at the cutoff.
A thoracic-oncology analyst reading the same public record on 2026-07-31 — NEJM-published positive phase 3, Breakthrough Therapy Designation, first-line sNDA submitted, a $600m upfront global license — would call listing highly likely and treat FDA review timing as the only serious question. Estimated by reconstructing that read, not by surveying analysts.
Comparator: Rung 6: Regulatory action (FDA sNDA approval). Date the FDA approves the first-line supplemental NDA, or a publicly announced decision that ends that pathway.

How someone else settles it
The rule is written so a reader with no view on the drug can apply it. That is the test of whether a forecast was specified or merely gestured at.
Resolves YES if any NCCN NSCLC guideline version dated on or before 2027-07-31 names sunvozertinib (or ZEGFROVY) anywhere in the initial-systemic-therapy recommendation set for EGFR exon 20 insertion mutation-positive metastatic non-squamous NSCLC, at any category (1, 2A, 2B, or 3) and whether or not it is marked preferred. The adjudicator reads the NSCLC algorithm page for initial systemic therapy in EGFR exon 20 insertion mutation-positive disease and the corresponding systemic therapy tables, in the latest version dated on or before 2027-07-31. Resolves NO if no such version names it there. Listing confined to subsequent-line or post-progression therapy does NOT count. Access requires free NCCN registration; no clinical judgement about the drug is needed to apply this rule.

No independent adjudicator has been named on this record yet. Until one is, resolution is a stated rule rather than a committed arrangement.
Reasoning
Why this number, and what would break it
Mechanism
Hypothesis, not access — NCCN panel deliberation is closed. Primary path: the US supplemental NDA for the first-line indication, submitted on or before 2026-07-14 and carrying FDA Breakthrough Therapy Designation in this setting, is granted priority review and approved inside the window; NCCN then incorporates the new indication at its normal post-approval cadence, which for this guideline has historically been one to two versions. Secondary path: the panel lists the agent ahead of FDA action on the strength of the NEJM-published randomized phase 3, which it does occasionally for breakthrough-designated agents in molecularly defined subsets. The two paths are not independent — both are driven by the same evidence event — which is why the forecast sits below the ceiling implied by the regulatory path alone.
Against
The WU-KONG28 control arm was platinum doublet alone, not the category-1 preferred regimen the guideline already lists; the guideline requires registration and version dates were unconfirmed at cutoff
When the proposition would be ill-posed
The proposition would be ill-posed if: NCCN restructures the EGFR exon 20 insertion pages such that 'initial systemic therapy' is no longer a distinguishable recommendation set; NCCN withdraws public version-dated distribution of the NSCLC guideline; or the agent is withdrawn from the US market, in which case no listing can occur and the proposition resolves NO on its plain terms rather than being voided. A brand-name change following the AstraZeneca license does not void it — the rule matches on the INN 'sunvozertinib' as well as the brand. Listing restricted to a narrower first-line population than the full exon20ins group still counts as YES, provided it is a first-line recommendation.
Frozen covariates
The state of the record at the cutoff
Recorded as they stood on 2026-07-31, including the 3 fields whose honest value was unknown. A covariate table with no unknowns in it has usually been tidied.
- review pathway
- FDA Breakthrough Therapy Designation granted for the first-line setting (per AstraZeneca release, 2026-07-14); the forecast object itself is an NCCN panel revision, which follows NCCN's continuous-update process rather than a statutory clock
- submission type
- supplemental New Drug Application — efficacy supplement for a new line of therapy in an already-approved molecule
- evidence class
- randomized, open-label, multinational phase 3 (WU-KONG28), published in the New England Journal of Medicine 2026-05-29 and presented as an ASCO late-breaking abstract
- pivotal n
- 324 randomized 1:1
- endpoint type
- progression-free survival by blinded independent central review (primary; 10.3 vs 7.5 months per BICR, HR 0.65, p=0.0008); overall survival not reported as mature at the 2026-01-16 data cutoff
- approved competitors in class
- 1 — amivantamab plus carboplatin/pemetrexed, FDA-approved first-line for EGFR exon20ins on PAPILLON, and widely reported as the NCCN category 1 preferred first-line option for this subset. The category claim is from secondary reporting, NOT from a primary source archived here: the guideline requires registration and was not retrievable for archiving at the cutoff. Load-bearing either way — the WU-KONG28 control arm was platinum doublet alone rather than this regimen, so the trial does not establish superiority over the standard the guideline already recommends, which is the main argument for a lower category or a slower listing.
- months since last guideline revision
- unknown — NCCN NSCLC version dates could not be confirmed against a primary source at the cutoff; the guideline itself requires registration and public secondary reporting of 2026 version dates was mutually inconsistent
- panel cycle position
- unknown — see months_since_last_guideline_revision. The NSCLC guideline is revised several times per year, so procedural opportunity within the window is effectively certain; where the window falls in the cycle is not known.
- sponsor request status
- unknown — NCCN does not publish manufacturer submission requests
- odac referral
- none announced as of the availability cutoff
- sponsor state change
- AstraZeneca took an exclusive global license from Dizal on 2026-07-14, with $600m upfront and up to $900m in milestones — a change in the commercial capacity behind guideline and reimbursement engagement, occurring 17 days before this cutoff
