Lutetium-177 (lutetium-177)

Pfizer Inc. · preclinical active

Lutetium-177 (generic name: lutetium-177) is a mCRPC drug developed by Pfizer Inc.. It is currently in preclinical development.

mCRPC

Lutetium-177 is a radioactive therapeutic agent that delivers targeted cancer-killing radiation directly to tumor cells. It works by binding to specific proteins on cancer cells and emitting radiation that destroys them from within. This approach allows for effective treatment while minimizing exposure to healthy tissue.

Likelihood of approval
8% vs 5% industry baseline
If approved by FDA: likely 2036–2040
Steps remaining: Phase 1 → Phase 2 → Phase 3 → NDA/BLA submission
Confidence: Low
Why this estimate
  • Baseline preclinical → approval rate +5.0pp
    Industry-wide preclinical drugs reach approval ~5% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Big-pharma sponsor +3.0pp
    Pfizer Inc. is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2036–2040
EMA EU 2037–2041 +0.7 yr
MHRA GB 2037–2041 +0.7 yr

Mechanism of action

Lutetium-177 is a radioactive isotope used in targeted cancer therapy. It works by being attached to molecules that seek out and bind to specific proteins found on the surface of cancer cells. Once these molecules find their targets, they deliver the Lutetium-177 directly to the tumor, where the radioactive element can do its work. Once bound to cancer cells, Lutetium-177 releases radiation in the form of particles that cause damage to the cell's DNA and other critical structures. This radiation is strong enough to kill cancer cells but works locally—meaning the damaging radiation mainly affects the cancer cells it's attached to rather than spreading throughout the body. This targeted approach offers an advantage over traditional chemotherapy: it can attack cancer cells while sparing many healthy cells that don't have the target protein. The radiation dose is concentrated where it's needed most, potentially making treatment more effective and causing fewer side effects compared to treatments that attack all cells indiscriminately.
