NextConsensus registered this probability on 2026-10-06. It is one of 14 registered FDA goal-date forecasts.

The proposition

What was claimed

The FDA takes an approval action on Vertex's Biologics License Application for povetacicept, submitted for accelerated approval, for the treatment of adults with IgA nephropathy, with an approval action date on or before 2026-11-30, the PDUFA target action date disclosed in Vertex's Form 10-Q filed 2026-08-04.

The estimate

The number and the baselines it has to beat

85% probability, method v0.1.0 · frozen at the 2026-10-06 cutoff

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

Authority base rate 70%

ESTIMATE FROM THE SHAPE OF THE CLASS, NOT AN ENUMERATED COUNT. Applications resting on uncontrolled or early-phase trials, or on surrogate endpoints, often under accelerated approval, meet their first goal date less often than those built on completed randomized trials. The calendar's own count does not exist yet.

Calendar cycle 65%

A clock-only model: the goal date is inside the window and FDA meets most goal dates, but first-cycle approval is less common on uncontrolled, early-phase or surrogate evidence.

Analyst proxy 85%

A nephrology analyst reading the same filings on 2026-10-01 would weigh priority review and a pre-specified interim analysis of a randomized phase 3 that the sponsor reports positive on all endpoints, with another IgA nephropathy medicine granted accelerated approval in July 2026 (SRC-005). Estimated by reconstructing that read, not by surveying analysts.

Regulatory action (FDA): 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 openFDA Drugs@FDA records returned by https://api.fda.gov/drug/drugsfda.json?search=openfda.generic_name:%22povetacicept%22&limit=100 and by https://api.fda.gov/drug/drugsfda.json?search=products.active_ingredients.name:%22POVETACICEPT%22&limit=100, read together (openFDA does not always fill the generic-name field for a new application), contain an application whose ORIG submission has submission_status AP and a submission_status_date on or before 2026-11-30, and the Drugs@FDA approval letter or label for that application names IgA nephropathy in its indication, with Vertex or a Vertex subsidiary as applicant. An approval for a narrower IgA nephropathy population than the applicant sought still resolves YES, as does accelerated rather than traditional approval. Resolves NO if no approval action is dated on or before 2026-11-30: a complete response letter, a goal-date extension, withdrawal or no action. The goal date is frozen as disclosed at the cutoff; a later extension does not move it, and an approval dated after 2026-11-30 resolves NO as occurred_after_deadline. Read no earlier than 2026-12-14. If openFDA has not refreshed by then, the Drugs@FDA web record (https://www.accessdata.fda.gov/scripts/cder/daf/, searched by the name povetacicept) governs. If neither lists the product, FDA's Purple Book (https://purplebooksearch.fda.gov/, searched by povetacicept) governs for the licensure date, with the approval letter for the indication. The application number was not public at the cutoff, so the rule reads by name; a suffix on the nonproprietary name or a proprietary name does not change the identification. Resolves unresolvable only if none of these sources can be read after the read floor. Resolves VOID, with the reason recorded, only if FDA withdraws every public record of approval actions named above without an equivalent public successor, so that no approval date for this product can be read; while any of them publishes it, the rule stands.

Source the rule names: https://api.fda.gov/drug/drugsfda.json?search=openfda.generic_name:%22povetacicept%22&limit=100, https://api.fda.gov/drug/drugsfda.json?search=products.active_ingredients.name:%22POVETACICEPT%22&limit=100, https://www.accessdata.fda.gov/scripts/cder/daf/, https://purplebooksearch.fda.gov/

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 (FDA action by goal 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
85% 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.
