Summary

This early-phase trial tested two experimental drugs, FdCyd and THU, taken by mouth for advanced solid tumors that had not responded to standard treatments. Fifty-nine adults received the drugs in 21-day cycles to see if they were safe and tolerable. The goal was to find a dose for future studies, not to prove effectiveness.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

FdCyd (5-fluoro-2'-deoxycytidine) and THU (tetrahydrouridine)

What this could lead to

If this works, it could point toward a new oral treatment option for advanced solid tumors that have not responded to standard therapies.

What could go wrong

This is a very early Phase I trial with only 59 participants, focused on safety and dosing. It is not yet proven to work, and side effects are unknown. Many early-stage cancer drugs do not advance to become treatments.
