NCT ID NCT07193511

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests a new drug called AVZO-103 in people with advanced bladder cancer or other solid tumors that have spread. The drug is designed to seek out and attack cancer cells while sparing healthy ones. The trial will enroll about 355 adults and is the first time this drug is being tested in humans, focusing on safety and whether 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
AVZO-103 (a drug that targets two proteins on cancer cells, Nectin4 and Trop2, to deliver a toxin directly to the tumor)
What this could lead to
If successful, this could provide a new treatment option for people with advanced bladder cancer or other solid tumors that have stopped responding to standard therapies.
What could go wrong
This is a very early first-in-human study, so the drug may not be safe or effective. Side effects could be serious, and the benefits seen in a small group may not hold up in larger trials.

This is an AI summary of the original study and may miss details. Read our disclaimer.
