The proposition

What was claimed

NICE publishes final technology appraisal guidance for the appraisal 'Efgartigimod for treating chronic inflammatory demyelinating polyneuropathy' [ID6409], with a publication date on or before 2026-11-18, the expected publication date shown on its in-development page (https://www.nice.org.uk/guidance/indevelopment/gid-ta11508) on 2026-09-24.

Target rungA step on the 12-rung ladder: rungs 1 to 4 are the evidence moving, rungs 5 to 7 are a guideline body, regulator, or payer acting. The ladder, rung by rung
Rung 7: Payer/coverage action — NCD, LCD, formulary change, step-therapy revision, or access expansion/restriction by CMS, MACs, or major commercial payers.

The estimate

The number and the baselines it has to beat

45% probability, method v0.1.0 · frozen at the 2026-09-26 cutoff

The alternatives it was registered against, each with the reasoning that produced it.

Authority base rate 50%

ESTIMATE FROM THE SHAPE OF THE CLASS, NOT AN ENUMERATED COUNT. The share of NICE technology appraisals published on or before the expected date shown about eight weeks earlier is not yet counted (docs/foundations/short-horizon-reference-classes.md §4.6 names it as the census the calendar builds). Expected dates are revised often, especially when a committee meeting does not reach a final recommendation.

Calendar cycle 60%

A clock-only model: NICE sets a provisional publication date a few weeks after a committee meeting that assumes the meeting reaches a final recommendation. A second committee meeting more often reaches a final recommendation than a first, which favours the date. Eight weeks from the second meeting to expected publication is on schedule if that meeting is final.

Analyst proxy 45%

A market-access analyst reading the same project pages on 2026-09-24 would weigh the stage of the appraisal, the negative draft guidance and the history of delays. Estimated by reconstructing that read, not by surveying analysts.

Technology appraisal (NICE): offered on judgment, with no calibration figure until 15 in the class have resolved.

Resolution

The rule that settles the forecast

Resolves YES if the NICE technology appraisal guidance page published from project ID6409 shows a publication date ('Published: <date>') on or before 2026-11-18, whatever the guidance recommends. The adjudicator finds the page from the in-development page above, which links to or redirects to the published guidance, or by searching nice.org.uk for ID6409. Resolves NO if the guidance is published after 2026-11-18, if the expected date is revised and nothing is published by 2026-11-18, if the appraisal is paused or suspended past that date, or if it is terminated. A terminated appraisal stays in the denominator and resolves NO, as registry/CALENDAR.md's rule for this class says. Resolves cancelled_external only if NICE removes the appraisal from its work programme without publishing anything. The frozen date is the one archived at the cutoff; a later revision does not move it. Read no earlier than 2026-11-25. The recommendation itself is a different question and is not scored here. Resolves VOID, with the reason recorded, only if NICE stops publishing technology appraisal guidance pages with publication dates, so that no publication date for this appraisal can be read from nice.org.uk or its successor; while a publication date can be read, the rule stands.

Readers: Resolver A, clinical methodology; Resolver B, payer evidence. The same two reader roles are assigned to every forecast registered so far.

What this record will show once it resolves

Beside every result, the count for its class (NICE guidance by scheduled date): registered, resolved, unresolved, and expired. One forecast is one instance, not a rate.

The finding
As the rule above reads it: occurred on time, did not occur, or left unscored.
The readers and their sources
Two reader roles read the source named above: Resolver A, clinical methodology; Resolver B, payer evidence. Who adjudicated it is named here, with the sources they read when the adjudication lists them. Being named as a reader means applying the frozen rule to the public record; it is not support for the estimate, the method, or NextConsensus.
The number against its baselines
45% beside three baselines, each scored by the same rule (squared error), so a reader can see how the record did against each of them.

Reasoning

What the number rests on

The facts it was built from are below, as they stood at the cutoff, with every source archived; each baseline above carries the reasoning that produced it. The written mechanism and the conditions that would make the proposition ill-posed were frozen with the record and are held in the ledger, which the hash on this page covers.

It says that, because of the uncertainties in the economic model, it is not possible to determine the most likely cost-effectiveness estimates. The consultation closed on 18 May 2026.
