Neuro-pharmacological Properties of Repurposed Posaconazole in Glioblastoma: A Phase 0 Clinical Trial

Stopped early · Early Phase 1

Conditions studied: Glioblastoma, Glioblastoma Multiforme, Glioblastoma Multiforme of Brain, Glioblastoma Multiforme, Adult

In brief

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.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥18 years
• Evidence of primary or recurrent HGG that in the opinion of the treating team would require surgical resection
• Karnofsky Performance Score (KPS) ≥ 60%
• ECOG ≤ 2
• Life expectancy greater than 12 weeks
• Adequate liver function defined as ALT, AST, ALP within 1.5x institutional upper limit of normal (for study drug arm only)
• Ability to swallow medication (for study drug arm only)
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) for the duration of study participation (for study drug arm only)
• Ability to understand and willingness to sign a written informed consent document
• Be able to comply with treatment plan, study procedures and follow-up examinations

You may not qualify if…

• Patients may not be receiving any other investigational agents while on study
• Patients who have known allergy to posaconazole or other azoles (for study drug arm only)
• Patients who have previously had a severe side effect, such as agranulocytosis and neutropenia, in conjunction with previous azole class drugs for a parasitic infection (for study drug arm only)
• Patients with a history of acute or chronic hepatitis (for study drug arm only)
• Patients with liver enzymes (ALT, AST, ALP) >1.5x above normal range for the laboratory performing the test (for study drug arm only)
• Patients who are taking metronidazole and cannot be safely moved to a different antibiotic greater than 7 days prior to starting posaconazole therapy (for study drug arm only)
• Patients who are taking any anti-convulsant medication that interferes with the cytochrome P450 pathway (e.g. phenytoin, phenobarbital, carbamazepine, etc.) and who cannot be switched to alternative medications such as keppra (levetiracetam) (for study drug arm only)
• Uncontrolled intercurrent illness such as chronic hepatitis, acute hepatitis, or psychiatric illness/social situation that would limit compliance with study requirements (for study drug arm only)
• Patients with a history of Addison's disease or other forms of adrenal insufficiency (for study drug arm only)
• Patient with little or no stomach acid production (achlorhydria) (for study drug arm only)
• Pregnant and breast feeding women)
• Patients with a history of any medical or psychiatric condition or laboratory abnormality that in the opinion of the investigator may increase the risks associated with the study participation or investigational product administration or may interfere with the interpretation of the results.
• Patients who are not available for follow-up assessments or unable to comply with study requirements.
• Patients who are currently taking medications that induce the metabolism of posaconazole, such as isoniazid, nevirapine, rifamycins (such as rifabutin, rifampin), or St. John's wort and cannot be safely discontinued off of them for the duration of the trial (for study drug arm only).
• Patients who are currently taking medications for which the metabolism may be affected by posaconazole, which include but are not limited to: benzodiazepines (such as alprazolam, midazolam, triazolam), domperidone, eletriptan, eplerenone, ergot drugs (such as ergotamine), nisoldipine, drugs used to treat erectile dysfunction-ED or pulmonary hypertension (such as sildenafil, tadalafil), some drugs used to treat seizures (such as carbamazepine, phenytoin), some statin drugs (such as atorvastatin, lovastatin, simvastatin) (for study drug arm only).
• Patients who are non-English speakers
• Patients who are not capable of understanding the consent form and would need a legally authorized representative.
