HIF-2 Alpha Inhibitor PT2385 in Treating Patients With Recurrent Glioblastoma

Completed · Phase 2

Conditions studied: Recurrent Glioblastoma

In brief

This phase II trial studies how well HIF-2 alpha inhibitor PT2385 works in treating patients with recurrent glioblastoma. HIF-2 alpha inhibitor PT2385 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

You may qualify if…

• • Patients must have histologically confirmed glioblastoma that is progressive or recurrent following radiation therapy and temozolomide according to the Response Assessment in Neuro-Oncology (RANO) criteria with:
• New contrast-enhancing lesion outside of radiation field on decreasing, stable, or increasing doses of corticosteroids
• Increase by >= 25% in the sum of the products of perpendicular diameters between the postradiotherapy scan with the smallest tumor measurement and a scan at least 12 weeks from completion of radiation therapy (RT) + temozolomide (TMZ), on stable or increasing doses of corticosteroids
• * Note: clinical deterioration not attributable to concurrent medication or comorbid conditions is sufficient to declare progression on current treatment but not for entry onto a clinical trial for recurrence
• Tumor O(6)-methylguanine-DNA-methyltransferase (MGMT) methylation status must be available; results of routinely used methods for MGMT methylation testing (e.g. mutagenically separated polymerase chain reaction, (MSPCR), or quantitative polymerase chain reaction (PCR)) are acceptable
• Patients must have a tumor tissue form indicating availability of archived tissue from a previous surgery for glioblastoma, completed and signed by a pathologist
• Patients must have measurable (defined by at least 1 cm x 1 cm) contrast-enhancing disease by magnetic resonance imaging (MRI) imaging within 21 days of starting treatment
• Patients must be able to undergo MRI of the brain with gadolinium; patients must be maintained on a stable or decreasing dose of corticosteroid regimen (no increase for 5 days) prior to this baseline MRI
• Patients must be in first recurrence of glioblastoma following radiation therapy and temozolomide
• Patients must have recovered from severe toxicity of prior therapy; the following intervals from previous treatments are required to be eligible:
• 12 weeks from the completion of radiation
• 6 weeks from a nitrosourea chemotherapy
• 3 weeks from a non-nitrosourea chemotherapy
• 4 weeks from any investigational (not Food and Drug Administration (FDA)-approved) agents
• 2 weeks from administration of a non-cytotoxic, FDA-approved agent (e.g., erlotinib, hydroxychloroquine, etc.)
• Patients must have a Karnofsky performance status >= 60% (i.e. the patient must be able to care for himself/herself with occasional help from others)
• Absolute neutrophil count >= 1,500/microliter (mcL)
• Platelets >= 100,000/mcL
• Hemoglobin >= 9 g/dL
• Total bilirubin =< institutional upper limit of normal
• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase (SGOT))/ alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase (SGPT)) =< 4 x institutional upper limit of normal
• Creatinine =< institutional upper limit of normal OR creatinine clearance >= 60 ml/min/1.73m\^2 for patients with creatinine levels above institutional normal
• Activated partial thromboplastin time (APTT) or partial thromboplastin time (PTT) =< 1.5 x institutional upper limit of normal
• Patients must be able to provide written informed consent
• Women of childbearing potential must have a negative serum pregnancy test prior to study start; women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and through 30 days after the last dose of study drug; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and through 30 days after the last dose of study drug

You may not qualify if…

• • Patients receiving any other investigational agents are ineligible
• Patients must not have received prior anti- Vascular endothelial growth factor (VEGF) therapy including bevacizumab (i.e. patients must be bevacizumab naive)
• Patients with a history of allergic reactions attributed to compounds of similar chemical or biologic composition to PT2385 are ineligible
• Patients on enzyme-inducing anti-epileptic drugs (EIAED) are not eligible for treatment on this protocol; patients may be on non-enzyme inducing anti-epileptic drugs or not be taking any anti-epileptic drugs; patients previously treated with EIAED may be enrolled if they have been off the EIAED for 10 days or more prior to the first dose of PT2385
• Patients with a history of bleeding diathesis are ineligible
• Patients who have not recovered to < Common Terminology Criteria for Adverse Events (CTCAE) grade 2 toxicities related to prior therapy are ineligible
• Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, clinically significant cardiac disease, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements, are ineligible
• Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with PT2385
• Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible due to potential drug-drug interactions with PT2385
