Summary

This trial is testing a new drug for prostate cancer that has spread and is resistant to hormone therapy. They will study how well the drug works and if it is safe.

Who is the study for?
This trial is for adult men with metastatic castration-resistant prostate cancer who have already tried at least one novel anti-androgen therapy and a taxane regimen, or cannot take taxane due to medical reasons. They must have a PSMA expressing tumor, no significant heart disease, no organ transplants, and no active serious infections.
What is being tested?
The study tests JANX007's safety, how well it's tolerated by the body (tolerability), its behavior in the body (pharmacokinetics), its effect on the body (pharmacodynamics), and initial effectiveness in treating advanced prostate cancer that resists standard treatments.
What are the potential side effects?
As this is a first-in-human study of JANX007, specific side effects are not yet known but may include typical reactions related to immune therapies such as fatigue, fever, allergic reactions or issues affecting organs where PSMA is present.
