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 Results may not be published yet.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 early-phase trial tests whether injecting methotrexate-loaded vesicles (tiny drug-carrying particles made from patients' own tumor cells) into the spinal fluid can safely treat lung cancer that has spread to the brain lining. About 14 adults who have failed standard treatments will receive the injections on a schedule. The study first finds the safest dose, then checks if it shrinks tumors.

What this could mean

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

Active substance
methotrexate-loaded vesicles (drug-carrying particles made from patients' own tumor cells)
What this could lead to
If it works, this could offer a new local treatment option for lung cancer that has spread to the brain lining, potentially controlling the disease and extending survival.
What could go wrong
This is a very early, small trial (14 people) testing safety and dosing first. The approach may not work or could cause serious side effects like nerve damage or infection from the spinal injections.
