⚠ Evidence cap applied: the model proposed 30%, brought back to 36% for lack of sources solid enough to justify the departure from the base rate.
Resolution criterion
Yes if, when NCT05667142 is read on clinicaltrials.gov on 30 July 2027, the exact API field protocolSection.statusModule.completionDateStruct.date — Study Completion Date is 30 June 2027 or earlier — that is, the date announced today has not been pushed back. A later recorded date counts as no. If OverallStatus is Terminated, Withdrawn, Suspended, or Unknown status, that counts as no — an unmaintained or halted record is treated as a failure to hold the date, not as a technicality. The value returned by the ClinicalTrials.gov API on the deadline prevails; where the record gives a month without a day, the last day of that month is used. If that exact field is absent or empty on an otherwise existing record, that also counts as no – a missing date is not evidence the deadline will be met, it is treated the same as a halted record.

What pushes it up
- The trial has been active since February 2023, indicating it is in its mature stages [1].
- Xenon Pharmaceuticals is actively supporting its key pipeline candidate, reducing the risk of termination [1].
What pushes it down
- The trial has been recruiting for over 3.5 years for only 160 participants, indicating very slow enrollment [1].
- The trial was still recruiting as of August 2026, leaving a very short window to complete enrollment and follow-up by April 2027 [1].
- The gap between primary completion (April 2027) and study completion (June 2027) is only two months, leaving no buffer for delays [1].
