Why 2026 is different

Four unlocks: (1) Novartis-Pluvicto (Lu-177-PSMA)-FDA-Mar-2022 metastatic-castration-resistant-prostate-cancer, expanded-Mar-2025 pre-taxane label, PSMAfore Phase-III positive, Novartis-Lutathera (Lu-177-DOTATATE) $500M+ 2024-run-rate proved theranostics, radioligand-therapy as a scaled, reimbursed, supply-constrained oncology modality — no longer research-only. (2) The $8B+ 2023-2024 pharma-radiopharma M&A wave — Bristol-Myers-Squibb-RayzeBio $4.1B-Dec-2023, Eli-Lilly-Point-Biopharma $1.4B-Oct-2023, AstraZeneca-Fusion-Pharmaceuticals $2.4B-Mar-2024, Novartis-Mariana-Oncology $1B-May-2024, Sanofi-Orano-Med — set the strategic-exit path for Ac-225 alpha-emitter platforms and made every top-15 oncology pharma a captive buyer. (3) CMS-Medicare-Part-B-Radiopharmaceutical-Payment-Reform-CY-2025-Nov-2024 introduced the High-Cost-Radiopharmaceutical-Payment-Policy separating high-cost radiopharmaceuticals from the APC bundle at ASP+6% — the first Medicare payment framework that meaningfully reimburses $30K-$200K Lu-177/Ac-225 doses, plus CMS-Enhancing-Oncology-Model-EOM-Jul-2023 mandating episode-based accountability at 25+ practices. (4) FDA-cleared adaptive-RT, biology-guided-RT — Varian-Ethos-adaptive-CBCT, Elekta-Unity-MR-Linac, RefleXion-SCINTIX-PET-guided-biology-guided-2023, MIM-Software-GE-HealthCare-May-2024-$500M+, Limbus-AI-Varian-May-2023, Radformation — collapsed contouring, planning, adaptation from hours to minutes, making daily adaptive workflows a hard-gated buying criterion, while Ac-225-U-233-DOE-Oak-Ridge-BWXT, ANSTO-Lu-177-n.c.a, NorthStar-Mo-99, TerraPower-Isotopes, Nusano supply-security became a Series-A gating item after 2022-2024 Lu-177 shortages.
