Notes

Added at stage 22: promoted from 'Reported once' (single-article, no diagnostic pair at discovery) because a full-text synthesis with extracted data exists in parsed-therapy.xlsx -- PMID(s): 33441295. Target/mechanism, clinical application, indications, approval and precursor fields still need per-agent research and are intentionally left empty. Compound class inferred from precursor name (not stated outright) -- PMID 33441295: 'Humanized 5A10 IgG1 mAb was developed by DiaProst AB (Lund, Sweden) and produced by Innovagen AB (Lund, Sweden)'. Stage set/updated at stage 23 from PMID 33441295: 'We present a complete preclinical evaluation of radiolabeled hu5A10 in mouse prostate cancer models and NHPs'. | Stage 30 (2026-09-18): Modality was 'Therapy' -- a bucket value given to every agent found by the therapy-oriented bulk search (stages 21-22), not a source statement. Corrected to PET: Zr-89 is a positron emitter used only for PET imaging. Linked articles: PMID 33441295, 42455315.
