Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase I/Ib trial tests the safety, side effects, and best dose of mycophenolate mofetil in combination with temozolomide and/or radiation therapy (standard of care) in treating patients with glioblastoma. Mycophenolate mofetil is an immunosuppressant drug that is typically used to prevent organ rejection in transplant recipients. However, mycophenolate mofetil may also help chemotherapy with temozolomide work better by making tumor cells more sensitive to the drug. The purpose of this trial is to determine if mycophenolate mofetil combined with temozolomide can stop glioblastoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVE:

I. To evaluate the recommended phase 2 dose (RP2D) for mycophenolate mofetil (MMF) in combination with radiation therapy as well as in combination with temozolomide (TMZ).

SECONDARY OBJECTIVES:

I. To evaluate the safety profile of mycophenolate mofetil (MMF) in combination with temozolomide (TMZ).

II. To estimate progression free survival (PFS) per Response Assessment in Neuro-Oncology Criteria (RANO).

III. To estimate overall survival (OS). IV. To estimate the overall response rate (ORR) per RANO criteria. V. To evaluate quality of life per Functional Assessment of Cancer Therapy Scale-Brain (FACT-Br) for patients treated with mycophenolate mofetil and/or temozolomide.

EXPLORATORY OBJECTIVES:

I. To investigate the relationship between the molecular signature of individual glioblastoma multiforme (GBM) with clinical outcome, by measuring levels of serum mycophenolic acid in patient's plasma post MMF administration.

Ia. Perform molecular characterization of all GBM tissues by ribonucleic acid sequencing (RNAseq) analysis.

Ib. Perform bulk metabolomics for GBM tissue. Ic. Measure plasma and serum concentration of mycophenolic acid, the MMF's primary active metabolite, during and after combination therapy.

Id. Measure IMPDH activity assay in patients' peripheral blood mononuclear cells (PBMCs) as well as in GBM tissue.

OUTLINE: This is a dose-escalation study of MMF (Part 1), followed by a dose-expansion study (Part 2).

PART 1: Patients are assigned to 1 of 3 groups.

GROUP 1: Patients who have already undergone surgery or biopsy followed by chemoradiation receive TMZ orally (PO) once daily (QD) on days 1-5 of each cycle and MMF PO twice daily (BID). Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

GROUP 2: Patients with unmethylated glioblastoma who have already undergone surgery or biopsy receive TMZ PO QD on days 1-5 of each cycle and MMF PO BID. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Starting at the same time as TMZ and MMF administration, patients also receive radiation therapy daily, 5 days per week, for 6 weeks.

GROUP S: Patients planning to undergo surgery receive MMF PO BID and TMZ PO QD for 5 days prior to surgery in the absence of disease progression or unacceptable toxicity.

PART 2: Patients are assigned to Group 3.

GROUP 3: Patients who have already undergone surgery or biopsy receive TMZ PO QD on days 1-5 of each cycle and MMF PO BID. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Starting at the same time as TMZ and MMF administration, patients also receive radiation therapy daily, 5 days per week, for 6 weeks.

After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 18 months.

Exclusion Criteria

* Patients who are receiving any other investigational agents.

* Exception: COVID-19 vaccine and treatment is allowed
* Patient who have a prior or concurrent malignancy that may interfere with study treatment or safety.

* Psychiatric illness/social situations that would limit compliance with study requirements. Any other illness or condition that the treating investigator feels would interfere with study compliance or would compromise the patient's safety or study endpoints.
* Female patients who are pregnant or nursing. Pregnant women are excluded from this study because temozolomide is an alkylating agent with potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with temozolomide, breastfeeding should be discontinued if the mother is treated with temozolomide.
* Patients who are unable to swallow oral medication or have problems/ diseases that affect absorption of oral medication.
* Patients with a known history of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and/or hepatitis C virus (HCV).

* Note: Temozolomide and mycophenolate mofetil are immunosuppressive agents. Patients with a known history of HIV, HBV, and HCV, and unexplained opportunistic infections are not eligible due to safety reasons
