Low vs Standard Dose Dexamethasone for Brain Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether a lower dose of dexamethasone, a corticosteroid, can control brain swelling as effectively as the standard dose after brain surgery. Dexamethasone reduces brain swelling but often causes many side effects. Researchers aim to determine if a reduced dosage can maintain effectiveness while minimizing side effects. This trial may suit individuals with a primary or metastatic brain tumor who can manage on a lower dose of dexamethasone before surgery. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.
Do I have to stop taking my current medications for the trial?
The trial protocol does not specify if you need to stop taking your current medications, but you must be able to reduce your dexamethasone dose to 3 mg every 12 hours by 3 days before surgery to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that dexamethasone can help reduce brain swelling. However, higher doses might cause more side effects without improving results. In past studies, patients on higher doses experienced more negative reactions, such as increased infections or mood changes.
Researchers are currently studying whether lower doses of dexamethasone can control brain swelling as effectively, but with fewer side effects. This trial is in the middle phase, indicating that early tests have suggested the treatment is fairly safe. However, more information is needed for confirmation.12345Why are researchers excited about this trial's treatments?
Unlike the standard of care for brain cancer, which often involves higher doses of dexamethasone, this treatment explores the effectiveness of lower doses. Researchers are excited because using a lower dose could minimize side effects while still effectively managing symptoms. This approach could lead to better quality of life for patients by reducing common steroid-related issues like weight gain, mood swings, and increased infection risk, without compromising on treatment efficacy.
What evidence suggests that low dose dexamethasone could be an effective treatment for brain swelling after surgery?
This trial will compare the effectiveness of standard-dose dexamethasone with lower-dose dexamethasone in reducing brain swelling after surgery for brain tumors. Research has shown that dexamethasone can help reduce brain swelling, and studies have found both regular and lower doses to be effective. One study suggested that lower doses might control swelling as well as regular doses, potentially leading to fewer side effects. Patients often take 4 mg twice a day, a common dosage that has improved conditions without added risk. The trial aims to find the lowest dose that effectively controls brain swelling while minimizing side effects.12467

Are You a Good Fit for This Trial?
This trial is for adults over 18 with primary or metastatic brain tumors, able to reduce pre-surgery dexamethasone to a specified level and undergo complete tumor removal. They must have stable vital signs, no active infections or other cancers, and not be in another clinical trial.Inclusion Criteria

Trial Overview
The study compares low versus standard doses of dexamethasone for reducing brain swelling post-surgery in patients with brain tumors. It aims to find the minimum effective dose that controls swelling while minimizing side effects.

Experimental Treatment
Active Control
Patients receive lower dose dexamethasone PO q 12 h for 3 days. On the day of surgery, patients receive lower dose dexamethasone IV before and after the surgery. Patients receive lower dose dexamethasone IV q 12 h on days 1-3 post surgery and tapered dexamethasone PO q 12 h on days 4-14 in the absence of disease progression or unacceptable toxicity. Additional doses of dexamethasone are given if needed.
