Summary

This early-stage trial is testing a new drug called TORL-1-23 in about 90 people with advanced solid tumors, including ovarian, endometrial, and lung cancers. The drug is an antibody drug conjugate designed to target and kill cancer cells. The main goals are to check safety, find the right dose, and see if it can shrink tumors.

What this could mean

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

Active substance
TORL-1-23 (an antibody drug conjugate)
What this could lead to
If successful, this could point toward a new treatment option for advanced cancers that have not responded to other therapies.
What could go wrong
This is an early Phase 1 trial with only 90 participants, so it is too soon to know if it works. Side effects are unknown, and the drug may not shrink tumors or improve survival.
