NextConsensus registered this probability on 2026-10-15. It is one of 26 registered FDA goal-date forecasts.

The proposition

What was claimed

The FDA takes an approval action on a supplement to NDA 217759 (leniolisib, JOENJA; applicant Pharming) whose approved labeling provides dosing for patients with activated phosphoinositide 3-kinase delta syndrome (APDS) weighing 13 kg to less than 27 kg, with an approval action date on or before 2027-01-30, the PDUFA target action date disclosed in Pharming's Form 6-K furnished 2026-09-25.

Rung 6: Regulatory action — Label/indication change, approval action, REMS modification, or withdrawal by FDA, EMA, PMDA, Health Canada, etc.

The estimate

The number and the baselines it has to beat

85% probability, method v0.1.0 · frozen at the 2026-10-15 cutoff

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

Authority base rate 85%

ESTIMATE FROM THE SHAPE OF THE CLASS, NOT AN ENUMERATED COUNT. Efficacy supplements to approved drugs are approved at their first goal date more often than original applications. The calendar's own count does not exist yet.

Calendar cycle 80%

A clock-only model: the goal date is inside the window, FDA meets most goal dates, and most first-cycle supplement actions are approvals.

Analyst proxy 85%

An analyst reading the same filings on 2026-10-01 would weigh priority review and FDA's approval of the previous pediatric supplement on 2026-09-11 against an open-label single-arm basis and a chief executive's sudden departure. 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 record for application NDA217759 (https://api.fda.gov/drug/drugsfda.json?search=application_number:%22NDA217759%22) contains a submission with submission_type SUPPL, submission_status AP and a submission_status_date on or before 2027-01-30, and the Drugs@FDA approval letter or label for that supplement provides dosing for patients with APDS weighing 13 kg to less than 27 kg. The supplement is identified by that content, not by its number or class code. At the cutoff the latest approved supplement was SUPPL 6, approved 2026-09-11, which added dosing for children aged 4 to 11 weighing 27 kg or more and is not this supplement (SRC-003). An approval covering part of the 13 kg to 27 kg range, or a narrower age range, still resolves YES. Resolves NO if no approval action is dated on or before 2027-01-30: 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 2027-01-30 resolves NO as occurred_after_deadline. 2027-01-30 is a Saturday; an approval action dated that day still counts. Read no earlier than 2027-02-13; if openFDA has not refreshed, the Drugs@FDA web record for NDA217759 (https://www.accessdata.fda.gov/scripts/cder/daf/) governs. Resolves unresolvable only if neither source 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.

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.
