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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are testing stereotactic body radiation therapy (SBRT) in adults whose cancer has spread to the spine and is pressing on the spinal cord. SBRT delivers high doses of radiation precisely to the tumor while limiting damage to nearby tissue. The trial enrolls 50 participants across multiple centers and gives treatment once daily over one to two weeks using the CyberKnife system. The main goal is to see whether the tumor stays controlled in the treated area and to track side effects.

What this could mean

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

Active substance
stereotactic body radiation therapy (SBRT), a focused high-dose radiation treatment
What this could lead to
If it works, SBRT could offer a non-surgical way to control spinal tumors that press on the spinal cord and help patients avoid or delay surgery.
What could go wrong
This is a single-arm phase II study with 50 participants, so it cannot prove SBRT is better than other options. Radiation near the spinal cord carries risks of nerve damage, and tumors may still grow back in the treated area.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 50 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Inclusion Criteria: * · Participants must be capable of understanding and voluntarily signing the written informed consent form;· Age ≥ 18 years;· (ECOG) performance status score ≤ 3;· The primary tumor is histologically or cytologically confirmed as a solid malignant tumor (excluding multiple myeloma, lymphoma, and germ cell tumors);· Has clear radiological evidence of spinal metastases;· Has acceptable spinal stability (Spinal Instability Neoplastic Score \[SINS\] ≤ 6, or between 7-12 but assessed as stable by surgical consultation), or has previous spinal instability that has been determined to be stable after surgical intervention;· Bilsky grade of spinal metastases confirmed by magnetic resonance imaging (MRI) as 1c-3;· Number of consecutive involved vertebral segments ≤ 3;· The involved vertebral level is above the conus medullaris;· Laboratory tests indicate adequate organ function. Exclusion Criteria: * ·Histologically confirmed primary spinal tumor or central nervous system disease;· Intramedullary lesions;· Prior radiotherapy to the same vertebral level;· Presence of contraindications to MRI examination;· Unable to lie flat for ≥ 30 minutes;· Presence of other severe comorbidities, such as uncontrollable cardiovascular disease, pulmonary disease, or other organ dysfunction, with poor overall health status and intolerance to treatment;· Pregnant or breastfeeding women;· Currently participating in other interventional clinical research treatments, or having received other investigational drugs or investigational device treatments within 4 weeks prior to the first treatment.
