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): 41275230. 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 41275230: 'CEA-Nanobody (CE-21-NOTA conjugate)'. Stage set/updated at stage 23 from PMID 41275230: 'A high-affinity CEA-targeted nanobody for 68Ga PET imaging and 177Lu-based radioisotope therapy: preclinical and first-in-human evaluation.'. | Stage 30 (2026-09-18): Stage was 'first-in-human'; normalised to 'Clinical research', original wording kept here. | 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: Ga-68 is a positron emitter used only for PET imaging. Linked articles: PMID 41275230.
