NCT ID NCT04384146

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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 study tested the safety of a special radiation schedule called Quad Shot for people with stage IV non-small cell lung cancer who are also receiving chemotherapy or immunotherapy. The Quad Shot delivers radiation in just 2 days per cycle, up to 3 cycles, to make it easier to fit with other treatments. 41 participants completed the study to see if this approach is safe and tolerable.

What this could mean

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

Active substance
Quad Shot radiation therapy
What this could lead to
If successful, this could offer a shorter, safer radiation schedule for advanced lung cancer patients, potentially easing symptoms without disrupting their ongoing treatment.
What could go wrong
This is an early phase I trial with only 41 participants, so results may not apply to all patients. There are risks of side effects like esophagitis or pneumonitis.

Inclusion Criteria: * Histologically confirmed non-small cell lung cancer with metastatic disease detected on cross-sectional imaging with a plan for one of the following systemic therapies: * Carboplatin/paclitaxel * Carboplatin/paclitaxel/pembrolizumab * Carboplatin/pemetrexed * Carboplatin/pemetrexed/pembrolizumab * Pembrolizumab (single agent or in combination with other regimens in this list) * Cisplatin/pemetrexed * Cisplatin/pemetrexed/pembrolizumab * Pemetrexed/pembrolizumab * Pemetrexed * Nivolumab (single agent or in combination with other regimens in this list) * Ipilimumab/nivolumab * Carboplatin/etoposide * Carboplatin/etoposide/atezolizumab * Cisplatin/etoposide * Cisplatin/etoposide/atezolizumab * Durvalumab (single agent or in combination with other regimens in this list) * Atezolizumab (single agent or in combination with other regimens in this list) * Patients eligible for the systemic therapy regimens notes * Patients with Stage IV NSCLC who have symptomatic (defined by patient-reported cough, dyspnea, or hemoptysis) or near-symptomatic (determined radiographically to be threatening the airway, esophagus or vasculature) centrally located. * KPS ≥ 60 * Age ≥ 18 years. * Able to provide informed consent. * Patients at reproductive potential must agree to practice an effective contraceptive method. Exclusion Criteria: * Previous radiotherapy to the intended treatment site that precludes developing a treatment plan that respects normal tissue tolerances. * Serious medical co-morbidities precluding radiotherapy. * Pregnant or breast-feeding women.
