Separately, 90% that any primary-endpoint result is public by that deadline. Conditional on a timely result, I judge a 78% chance of a positive primary endpoint; 0.90 x 0.78 = 0.702, rounded to 70%. These are judgmental probabilities, not outputs of a fitted trial-power model. Resolution: YES if a Boehringer Ingelheim press release, ClinicalTrials.gov result for NCT06151574, peer-reviewed paper, or ASCO/ESMO/WCLC/ELCC/AACR abstract published by 2027-12-31 states that the primary PFS endpoint was met with statistical significance. NO if one reports it was not met, or none reports that endpoint by the deadline.\n\nEvidence read 2026-10-01. [Registry record] NCT06151574 is randomized phase 3, zongertinib versus pembrolizumab plus platinum-pemetrexed; enrollment is 428 actual; primary completion is estimated 2026-12-10; status is active, not recruiting; no results are posted; last update posted 2026-09-22. Its open-label treatment is tempered for the primary endpoint by blinded independent central review. [Peer-reviewed trial report] Beamion LUNG-1 first-line single-arm cohort (74 treated) reported 76% objective response and 14.4 months median PFS on zongertinib. [Peer-reviewed observational study] In LC-SCRUM-Asia, first-line chemotherapy plus immunotherapy for HER2-mutant NSCLC had median PFS 8.5 months (95 treated). [Peer-reviewed randomized trial] KEYNOTE-189 reported 8.8 months median PFS for pembrolizumab plus platinum-pemetrexed in a broader, non-HER2-selected NSCLC population. These are contextual benchmarks, not head-to-head estimates for the LUNG-2 population. [FDA review] The confirmatory LUNG-2 study had an expected primary PFS topline in Q1 2027 in the review record, consistent with a 2027 report but subject to delay. [FDA approval notice] The 2026 first-line accelerated approval relied on single-arm LUNG-1, not a positive LUNG-2 result.\n\nCompeting explanations: The strong first-line response and PFS signal plus HER2 targeting favour a positive result. The comparator is active; single-arm phase 1 patients and follow-up can overstate an apparent cross-trial advantage; randomized phase 3 PFS could be smaller or nonsignificant. Timing has separate risk: the registry completion date is an estimate, and analysis/publication can move beyond 2027. My 78% efficacy judgment discounts the cross-trial signal for these risks, while the 90% reporting judgment reflects completed enrolment and the near-term estimated primary completion. A negative report is possible even if the drug has some clinical benefit; absence of a report by the deadline resolves NO under this task.\n\nPrior-art recheck 2026-10-01: the registry still has no results; Europe PMC search for (\"Beamion LUNG-2\" OR NCT06151574) AND (RESULTS OR endpoint OR efficacy) returned 17 records, whose titles were screened and were reviews/design or other studies, with no phase 3 result; Manifold API searches for Beamion LUNG-2 and zongertinib returned zero markets; web searches for Beamion LUNG-2 topline, primary endpoint met, and a numerical forecast found no external published answer.
