Summary

It is being tested alone or with other standard treatments in 183 men with prostate cancer that has spread to other parts of the body. The main goal is to check safety and find the best dose.

What this could mean

Active substance

ARX517 (a drug that targets prostate cancer cells and delivers a toxin to kill them)

What this could lead to

If it works, this could point toward a new treatment option for men with advanced prostate cancer that has spread.

What could go wrong

This is an early Phase 1 trial, so the main goal is safety, not effectiveness. The drug may not work well or could have serious side effects.
