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 This study
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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether precisely targeted radiation (SABR) to a small number of growing tumors, while continuing current drug therapy, can delay overall disease progression in people with metastatic non-small cell lung cancer. About 68 participants whose cancer has started to grow in just 1 to 5 spots will be randomly assigned to receive either SABR plus their ongoing therapy or standard care, which may include switching to a new treatment. The study aims to see if this focused approach can buy more time before the cancer advances further.

What this could mean

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

Active substance
stereotactic ablative radiotherapy (SABR) to oligoprogressive lesions, plus continuation of current systemic therapy
What this could lead to
If successful, this approach could offer a way to extend the effectiveness of current systemic therapy by delaying the need to switch treatments.
What could go wrong
This is a small phase II trial, so results may not be definitive. Radiation carries risks like fatigue or damage to nearby organs, and the benefit over standard care is uncertain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥18 years * Metastatic NSCLC enrolled in our CRCHUM Lung Cancer Registry and co-enrolled to the PERa registry * Ability to provide written informed consent * Eastern Cooperative Oncology Group (ECOG) performance status 0-3 * Oligoprogression to 1-5 extracranial lesions ≤ 5cm and involving ≤ 3 organs. Progression at the primary tumor site should be counted within the total of 5 lesions. For patients with lymph node metastases, each node is counted as one site of metastasis. * Oligoprogression while on ICI or TKI (any line) * Patients with brain metastasis are allowed; brain metastasis are not counted in the maximum number of lesions and should be treated as per standard of care * All sites of disease can, in the opinion of the investigator, be safely treated and targetable with SABR (taking into account prior local therapy, organ function and underlying medical condition such as inflammatory bowel disease, pulmonary fibrosis, etc.) * Patients with prior metastases that have been treated with ablative therapies (e.g. radiotherapy, surgery or radiofrequency ablation) before their current line of systemic therapy, are eligible. Exclusion Criteria: * Any lesion beyond 5 cm * Pregnancy or breastfeeding * Any medical condition that could, in the opinion of the investigator, preclude radiotherapy or prevent follow-up after radiotherapy. * Presence of spinal cord compression Metastatic disease that invades the GI tract (including esophagus, stomach, small or large bowel)
