Active Surveillance for Brain Cancer
(ACTION-Brain Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether some individuals with brain cancer can safely avoid radiation therapy if their brain tumors respond well to other treatments, such as immunotherapy or targeted therapy. It targets patients with brain metastases from solid tumors, including non-small cell lung cancer, who are starting or planning to start systemic therapy expected to affect the brain. Suitable candidates for this trial have at least one brain tumor not planned for immediate surgery or radiation and are about to begin treatment that can reach and act on the brain. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group of participants.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop your current medications. However, you must be starting or planning to start a new systemic therapy that can affect the brain, like immunotherapy or targeted therapy.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Previous studies have shown that treatments working throughout the body, such as immunotherapy and targeted therapy, have promising safety results for patients with cancer that has spread to the brain. Research on HER2-positive brain metastases found that treatments like trastuzumab were well-tolerated and effective in the brain. Specifically, one study showed that 71% of patients experienced noticeable improvement without major safety concerns.
While these treatments are generally safe, individual reactions can vary. Some people may experience side effects like tiredness or nausea, but serious problems are less common. Prospective participants should discuss possible risks and benefits with a doctor. This trial aims to avoid using radiation, so understanding the safety of these body-wide treatments is crucial.12345Why are researchers excited about this trial?
Researchers are excited about active surveillance for brain cancer because it offers a non-invasive approach that relies on regular monitoring instead of immediate invasive treatments like surgery or radiation. This method involves using systemic therapies, such as immunotherapy or targeted agents, only when necessary, allowing patients to avoid the side effects of radiation unless their condition worsens. By focusing on regular MRI check-ups and using radiation only if progression is observed, this approach could lead to better quality of life for patients while still effectively managing the disease.
What evidence suggests that active surveillance could be effective for brain metastases?
Research has shown that systemic therapies, which work throughout the body, hold promise for treating cancer that has spread to the brain. In this trial, participants with brain metastases will receive standard-of-care systemic therapy expected to have intracranial activity, such as immunotherapy, targeted therapy, or anti-HER2 agents. One study found that 58.9% of patients receiving these treatments did not experience cancer progression for at least 12 months. Another study showed similar results, with 61.6% of patients maintaining stable disease for 12 months and 71% experiencing significant improvement in brain tumors. These treatments can cross into the brain and have been particularly effective for certain types of cancer, like HER2-positive cancers. By using MRI scans to monitor progress and continuing these treatments, some patients in this trial may avoid radiation therapy if their condition remains stable.13467

Are You a Good Fit for This Trial?
This trial is for patients with brain metastases from lung cancer or other solid tumors, who are starting treatments expected to cross into the brain. They must have at least one brain tumor not scheduled for radiation/surgery and be able to undergo MRI scans.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Active Surveillance
Trial Overview
The study tests if certain patients can skip radiation therapy after their brain tumors respond well to systemic therapies like immunotherapy, targeted therapy, or chemotherapy. It involves regular MRIs to monitor tumor response.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Participants with brain metastases from solid tumors will receive standard-of-care systemic therapy expected to have intracranial activity, such as immunotherapy, targeted therapy, or anti-HER2 agents. A re-evaluation brain MRI will be performed 4-8 weeks after starting therapy. If lesions are stable or responding, patients will continue on systemic therapy with MRI surveillance every 3 months. Radiation therapy may be administered only if progression is observed. All participants are managed according to this pathway, regardless of primary tumor type.
