NCT ID NCT04511845

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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

Summary

This early-phase trial is testing an experimental drug called SPYK04 in people with advanced solid tumors that have stopped responding to standard treatments. The main goal is to check the drug's safety and find the right dose. Researchers will also look for early signs that SPYK04 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
an experimental drug called SPYK04
What this could lead to
If SPYK04 proves safe and shows signs of shrinking tumors, it could lead to a new treatment option for people with advanced solid cancers that have stopped responding to other therapies.
What could go wrong
This is a very early (Phase 1) trial with a small number of participants, so the drug may turn out to be ineffective or have unacceptable side effects. It is far from being a proven treatment.
