What is the purpose of this trial?

This trial aims to determine if the drug posaconazole can reach and affect brain tumors known as glioblastomas. Although typically used for fungal infections, researchers believe posaconazole might also inhibit the growth of brain tumor cells. Participants will take posaconazole before surgery to assess its effectiveness against these challenging tumors. Individuals with glioblastoma who plan to undergo surgery may qualify for this trial. As an Early Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants an opportunity to contribute to groundbreaking medical knowledge.

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.

Is there any evidence suggesting that posaconazole is likely to be safe for humans?

Research shows that posaconazole is generally well-tolerated for treating fungal infections. As an approved medication, its safety is well-understood. In studies, patients have not reported any major effects on the brain, even when administered through an IV. This suggests that posaconazole might be safe for treating brain-related conditions.

Although this trial is in its early stages, the FDA approval of posaconazole for other uses provides some reassurance about its safety. However, since this is an early-phase study, complete safety information for its use in treating brain tumors is not yet available. Researchers will closely monitor participants to quickly address any side effects. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about posaconazole for glioblastoma because it offers a novel approach to treating this aggressive brain cancer. Unlike standard treatments such as surgery, radiation, and chemotherapy, posaconazole is an antifungal medication that targets cancer cells through a different mechanism. Its potential to disrupt cell growth pathways unique to glioblastoma could lead to more effective management of the disease. Additionally, posaconazole is taken orally, which may provide a more convenient treatment option compared to traditional intravenous therapies.

What evidence suggests that posaconazole might be an effective treatment for glioblastoma?

Research has shown that posaconazole, a drug originally used to treat fungal infections, may help fight glioblastoma, a type of brain tumor. In lab studies, posaconazole slowed tumor growth and killed cancer cells by stopping them from dividing and growing. This trial will include some participants receiving posaconazole to further investigate its potential as a treatment for glioblastoma. Although these findings are early, they suggest posaconazole could be a useful treatment for glioblastoma if further studies confirm its effectiveness. ^{1 3 4 6 7}

Are You a Good Fit for This Trial?

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.

What Are the Treatments Tested in This Trial?

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.

How Is the Trial Designed?

Group I: Posaconazole Experimental Treatment 1 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: Control Active Control 1 Intervention

Participants will not undergo any intervention.

Published Research Related to This Trial

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.

Posaconazole is a potent antifungal agent effective against a wide range of fungi, including Candida spp. and Aspergillus spp., and is particularly beneficial for immunocompromised patients, such as those undergoing chemotherapy or organ transplants.

Its absorption is significantly enhanced when taken with food, and it has a long half-life of 15-35 hours, making it important to administer it properly to ensure optimal therapeutic effects.
