Trial Summary

Will I have to stop taking my current medications?

You may need to stop taking certain medications if they interfere with the study drug, posaconazole. Specifically, if you are taking medications like metronidazole, certain anti-convulsants, or drugs that affect posaconazole's metabolism, you might need to switch to alternatives or stop them. It's best to discuss your current medications with the study team to see if any changes are needed.

How does the drug Posaconazole differ from other treatments for glioblastoma?

Posaconazole is unique because it is primarily an antifungal drug with a broad spectrum of activity, and it is being explored for glioblastoma, a type of brain cancer, which is not its usual use. Its novel application in glioblastoma may involve its ability to penetrate tissues effectively, but this is different from standard cancer treatments that typically target cancer cells directly.12345

What is the purpose of this trial?

This research is being done to find out if the study drug (posaconazole) can enter brain tumors at a high enough amount to stop the tumor cells from dividing. Posaconazole is a drug which doctors already use for fungal infections and is thought to be able to effect tumor cells. As treatments for this type of brain tumor are limited, it is hoped that the results of this study will help to determine if the study drug should be studied further as a possible treatment.

Eligibility Criteria

Adults over 18 with glioblastoma, a type of brain tumor, who are expected to live more than 12 weeks and need surgery. They must be able to swallow pills, have good liver function, use birth control if needed, understand the study consent form, and follow the treatment plan. People can't join if they're on certain drugs that affect posaconazole or have specific health issues like severe allergies to azoles.

Treatment Details

Interventions

  • Posaconazole
Trial Overview The trial is testing whether Posaconazole, a drug normally used for fungal infections, can reach high enough levels in brain tumors to stop cancer cells from growing. It's being considered as a new treatment option for glioblastoma because current treatments are limited.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: PosaconazoleExperimental Treatment1 Intervention
Participants will be taking 300 mg of the study drug (three 100 mg tablets) by mouth twice a day the first day and then 300 mg once a day until the day of biopsy or surgery. On the day of biopsy or surgery, participants will take their medication the morning of their biopsy or surgery (before the operation). Participants will then take the last dose of the medication in the morning of the day after their biopsy or surgery. Participants will be given 12 days' worth of the study drug (pills) and verbally instructed how and when to take them.
Group II: ControlActive Control1 Intervention
Participants will not undergo any intervention.

Findings from Research

Posaconazole is an effective antifungal agent approved for preventing and treating invasive fungal infections, particularly in patients with weakened immune systems, such as those undergoing stem cell transplants.
The new gastro-resistant tablet formulation of posaconazole offers significant pharmacokinetic advantages over the oral suspension, including improved absorption, less variability between patients, and the convenience of once-daily dosing, making it the preferred choice for optimizing treatment efficacy.

A study using MRI on adult and juvenile Beagle dogs showed that the intravenous administration of posaconazole (Noxafil) did not affect brain ventricle volume over three months, indicating its safety regarding brain development in older dogs.
The research highlighted significant natural variability in brain ventricle sizes among dogs, which is important for accurately interpreting the effects of treatments like posaconazole and supports its potential use in children over two years of age.

Posaconazole, currently in phase III clinical trials, demonstrates broad-spectrum antifungal activity against various fungi, including Candida, Aspergillus, and zygomycetes, making it a promising option for treating invasive fungal infections.
The drug is well tolerated with mild side effects, such as headaches and gastrointestinal issues, and has shown clinical efficacy in treating severe fungal infections that are resistant to existing therapies.
