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): 40733128. 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 40733128: 'NOTA-iPD-L1'. | 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: F-18 is a positron emitter used only for PET imaging. Linked articles: PMID 40733128. Stage set/updated at stage 39 from PMID 40733128: 'Biodistribution in mice bearing 4T1 tumors was performed, and molecular imaging (Cerenkov images) of [18F]AlF-NOTA-iPD-L1 and [177Lu]Lu-DOTA-iPD-L1 in the same mouse was obtained.'.
