Radiopharma for investors

For: Analysts and investors sizing up theranostics

The science, the approved products, the supply bottleneck, and the alpha-emitter pipeline that drives the M&A.

  1. 1
    Front
    Radiopharmaceuticals & Theranostics

    A molecule that homes to the tumour carries a radioactive atom. The same molecule with a different atom lets you see the tumour first.

    Why here The front and its constraint: isotope supply.

  2. 2
    Term
    Theranostics

    Using the same targeting molecule for a diagnostic scan and a therapy, so you treat exactly what you can see.

    Why here The see-then-treat paradigm in one term.

  3. 3
    TechnologyStandard of care
    PSMA PET

    A prostate-cancer-specific PET scan that finds spread far earlier than CT or bone scan, and tells you whether a matched radioactive drug will work.

    Why here The gatekeeper scan that defines the treatable population.

  4. 4
    ProductApproved
    Lutetium-177 vipivotide tetraxetan

    A radioactive drug that seeks out PSMA on prostate cancer cells; the best-selling radiopharmaceutical ever.

    Why here The best-selling radiopharmaceutical and its label history.

  5. 5
    TechnologyApproved
    Radioligand therapy (beta emitters)

    A drug that finds tumour cells and carries a radioactive atom that irradiates them from inside the body.

    Why here How beta emitters work and their limits.

  6. 6
    Term
    Alpha vs beta emitters

    Beta particles (lutetium-177) travel millimetres and are good for bulky disease; alpha particles (actinium-225) travel a few cells' width and kill with far higher energy.

    Why here Why actinium is the prize.

  7. 7
    TechnologyPhase 3
    Targeted alpha therapy

    Like radioligand therapy but with alpha particles: far more destructive over a much shorter range, so single cells can be killed with less collateral damage.

    Why here The phase 3 alpha programmes and the supply problem.

  8. 8
    Company
    TerraPower Isotopes

    Bill Gates-backed producer of actinium-225 from thorium-229, building a Philadelphia facility to raise supply 20-fold.

    Why here Who is scaling actinium-225.

  9. 9
    Target
    FAP

    FAP is a protein on the scaffolding cells that surround many tumours, so it lights up almost any solid cancer on a PET scan.

    Why here The pan-cancer stromal target that could widen the market.

  10. 10
    Pairing
    Beta radioligand → alpha radioligand

    After lutetium therapy stops working, an actinium version of the same drug can still produce responses.

    Why here The sequencing thesis.

  11. 11
    Roadmap
    Radiopharmaceutical roadmap: iodine → lutetium → actinium

    The radiopharmaceutical roadmap runs eighty years from radioactive iodine for thyroid cancer to alpha-emitting drugs for prostate and neuroendocrine cancers, with isotope supply as the limiting factor.

    Why here The whole arc, historic to speculative.
