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 Results may not be published yet.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 Phase 1 trial tests D3L-002, a new drug that targets two immune checkpoints (TIGIT and PVRIG) to help the immune system fight cancer. It is for 24 adults with advanced solid tumors that have not responded to standard treatments. The main goals are to check safety, find the right dose, and see early signs of tumor shrinkage.

What this could mean

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

Active substance
D3L-002 (a bispecific antibody that targets two immune checkpoints, TIGIT and PVRIG)
What this could lead to
If this early trial shows safety and hints of tumor shrinkage, it could lead to a new treatment option for people with advanced solid tumors that have stopped responding to other therapies.
What could go wrong
This is a very early Phase 1 study with only 24 people, focused on safety and dosing. It is too soon to know if D3L-002 will work against cancer, and it may cause side effects or show no benefit.
