Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This early-stage trial tests a new drug called LY4101174 in people with advanced solid tumors, including bladder, breast, and lung cancers. The drug is an antibody-drug conjugate designed to target and kill cancer cells. The study will check if the drug is safe, tolerable, and effective, and will involve about 490 participants over up to 4 years.

What this could mean

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

Active substance
LY4101174 (an antibody-drug conjugate targeting Nectin-4)
What this could lead to
If successful, this could lead to a new treatment option for several advanced cancers that have stopped responding to other therapies.
What could go wrong
This is an early Phase 1 trial, so the drug may not be effective or could have serious side effects. It is still being tested for the right dose and safety.
