NCT ID NCT06265727

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 Results may not be published yet.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.

Summary

This study tests a drug called CRB-701, which is designed to find and attack cancer cells that have a protein called Nectin-4 on their surface. The trial includes 348 adults with advanced solid tumors that have not responded to standard treatments. Researchers aim to find a safe and effective dose and see if the drug 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
CRB-701 (an antibody-drug conjugate that targets Nectin-4, a protein on cancer cells) and an anti-PD-1 checkpoint inhibitor
What this could lead to
If successful, this could provide a new treatment option for people with advanced solid tumors that have stopped responding to other therapies.
What could go wrong
This is an early-phase trial (Phase 1/2) with a small number of participants, so the drug may not prove effective or may have significant side effects. Results may not apply to all cancer types.
Why investors are watching

Corbus Pharmaceuticals is testing CRB-701, an antibody-drug conjugate that targets a protein called nectin-4, in patients with advanced solid tumors. For a very small company, this early-stage trial is a central test of whether its lead drug candidate can safely shrink tumors and in which cancers. The result will shape the company's future research priorities and its ability to attract partners or funding.

If it works: If the trial shows CRB-701 is safe and shrinks tumors in some patients, Corbus could advance the drug to later-stage testing and potentially broaden its pipeline. A positive readout may also increase interest from larger drug companies looking to collaborate or license the drug.

If it fails: The trial could fail to show enough safety or tumor response, which would likely force Corbus to abandon or rethink CRB-701. Early-phase cancer trials often fail, and for a micro-cap company, a setback with its main drug candidate could be a serious blow to its prospects.
