Clinical Trial Summary

This phase I trial tests the safety, side effects, and best dose of dexamethasone when given with azeliragon in managing cerebral edema after surgery (post-resection) in patients with glioblastoma. Cerebral edema is a pathological increase in the water mass contained within the brain interstitial space. Dexamethasone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Azeliragon is an oral RAGE inhibitor. Blocking the RAGE pathway at the time of surgery (peri-operatively) may decrease cerebral edema. Giving dexamethasone with azeliragon may help control post-operative cerebral edema in decreasing doses of concurrently administered dexamethasone.

Description:

PRIMARY OBJECTIVES:

I. Determine the lowest dose of dexamethasone that needs to be co-administered with azeliragon for treatment of post-resection cerebral edema in patients with glioblastoma.

II. Assess the safety of administering azeliragon peri-operatively to patients with glioblastoma.

SECONDARY OBJECTIVES:

I. Describe post-operative changes in levels of cytokines and chemokines in brain interstitium and peripheral blood in study participants.

II. Quantitatively assess changes in the volume of cerebral edema post-operatively in study participants.

III. Determine brain concentrations of azeliragon in resected tumor tissue from Arm 1 participants.

EXPLORATORY OBJECTIVES:

I. Describe post-operative changes in levels of RAGE ligands in brain interstitium, peripheral blood, and resection cavity fluid (when possible to obtain) in study participants.

II. Describe changes in levels of cytokines, chemokines, and immune cell populations in resection cavity fluid (when possible to obtain).

III. Describe differences in levels of cytokines, chemokines and RAGE ligands between patients in Arm 1 and Arm 2.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive azeliragon orally (PO) and dexamethasone PO or intravenously (IV) throughout the study. Patients also undergo collection of cavity fluid and blood samples, computed tomography (CT) scan, and brain magnetic resonance imaging (MRI) with or without contrast throughout the study.

ARM II: Patients receive dexamethasone PO or IV throughout the study. Patients also undergo collection of cavity fluid and blood samples, CT scan, and brain MRI with or without contrast throughout the study.

• International normalized ratio (INR) OR prothrombin (PT) =< 1.5 x ULN

• Activated partial thromboplastin time (aPTT) =< 1.5 x ULN

• Corrected QT (QTc) =< 480 ms

• Note: To be performed within 28 days prior to day 1 of protocol therapy

• People of childbearing potential: negative urine or serum pregnancy test

• Agreement by people of childbearing potential to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 3 months after the last dose of protocol therapy

• Childbearing potential defined as not being surgically sterilized (regardless of gender) or not being free from menses for > 1 year (people with uteri only)

Exclusion Criteria:

• Less than 6 weeks since taking a nitrosourea-containing chemotherapy regimen; less than 4 weeks since completing a non-nitrosourea-containing cytotoxic chemotherapy regimen (except temozolomide: only patients with an interval of less than 23 days from the last dose administered when treated with the temozolomide regimen of daily for 5 days, repeated every 28 days are excluded); less than 2 weeks from taking the last dose of a targeted agent; less than 4 weeks from the last dose of bevacizumab

• Less than 3 months since focal brain radiation unless recurrent disease has been confirmed surgically or the area of recurrent tumor is outside of the radiation field
