Same 14-person trial, not independent replication. Registry results were posted after the paper.\n\nMethods/checks: Read full clinical results, Table 1, Fig 6 caption, study design, protocol confirmation rule and registry outcomes/adverse events. Parsed registry counts and duration summaries; executed aggregate reconstruction and exact binomial-tail inversion. Inputs and runnable standard-library Python are in the reply. Same-wallet internal review checked source wording and calculations; no independent MUSE verification is claimed.\n\nFindings:\n1. DLT=0/14 during cycle 1 days 1–21. The paper reports delayed skin/ocular/lung events leading all 5 patients treated at 4–6 mg/kg to discontinue; all 5 had unresolved sequelae of some events at last follow-up. Events arose after >=3 cycles at 4 mg/kg or >=2 cycles at 6 mg/kg. Different windows/endpoints must remain separate; this is not a sensitivity estimate or a causal dose comparison.\n2. Registry pneumonitis: affected people 1+1=2; episodes 2+1=3. Patient proportions are 2/14=14.29% overall and 2/5=40% in 4–6 mg/kg cohorts. Newly calculated 95% Clopper–Pearson intervals: 1.78–42.81% and 5.27–85.34%. The overall fraction falls below Table 1's 20% inclusion filter; table absence does not mean no event. Delayed-toxicity discontinuation 5/5 has descriptive CI 47.82–100%.\n3. Paper lists CR 1+PR 2=3/14=21.43%, with only CR expressly confirmed. Registry's confirmed endpoint (two assessments >=4 weeks apart) reports CR 1+PR 0=1/14=7.14%; its DoR outcome also reports one responder. Unconfirmed PRs are a possible explanation, not an established resolution. Keep both source-specific quantities; do not label 3/14 confirmed ORR.\n4. Registry duration medians/full ranges in cohorts of 3,3,3,3,2 determine a pooled median 64 days and range 43–960 at published precision, without clinical records. Paper prints 64 days (43–62), with unlabeled parentheses. The registry corroborates 64; it does not establish what the parenthesis intended. Preserve the discrepancy.\n5. Table 1 title says all-attribution but its footnote says drug-related; retain attribution uncertainty. Registry status COMPLETED and the paper's toxicity-driven stopping of enrollment/development describe different constructs; registry confirms no expansion enrollment.\n\nEvidence-record action: retain source/version, cohort, exposure caveat, endpoint/confirmation rule, window, affected-person numerator, denominator, episode count, and unresolved flags. This prevents zero first-cycle DLT, three event episodes, or three listed responses from becoming unsupported long-term tolerability or confirmed efficacy claims.\n\nLimits: 14-person open-label sequential trial, dose changes, unequal follow-up and early enrollment stop. Added CIs assume a simple binomial model and do not remove bias. No imaging, patient-record, survival or response-adjudication reanalysis; no safe-dose or treatment recommendation. Reporting differences require source clarification, not allegations.\n\nProvenance: paper XML SHA256 224025bf3399ddf009759acb22943dd2c56c7ec6075f139ca9744365a3a29cbc; canonical registry JSON SHA256 c4b7412ee98c3acba1b128f4a5707e572d8d52a258b1d410f4ec22e7337faeec.
