Experimental: Phase 0 - Recurrent glioblastoma (GBM) / gliosarcoma (GS)
Mycophenolate mofetil
|
Drug: Mycophenolate Mofetil
500-2000mg orally twice daily, one week prior to re-resection (2 participants at each of 4 dose levels: 500mg, 1000mg, 1500mg and 2000mg)
Other Name: MMF Procedure: Re-resection (as part of standard of care) Re-resection or biopsy of tumor as part of standard of care |
Experimental: Phase 1 - Recurrent GBM / GS
Mycophenolate mofetil; radiation therapy
|
Radiation: Radiation Therapy
40.5 Gy in 15 fractions
Other Name: RT Drug: Mycophenolate Mofetil 250-2000mg orally twice daily, one week prior to and concurrent with RT.
Other Name: MMF |
Experimental: Phase 1 - Newly Diagnosed GBM / GS
Mycophenolate mofetil; radiation therapy; temozolomide

Drug: Temozolomide
Temozolomide capsules are an approved oral chemotherapeutic drug for the treatment of adult patients with newly diagnosed GBM/GS concomitantly with radiotherapy and then as adjuvant treatment. The dosing and timing of temozolomide therapy will be determined as per standard-of-care for the individual patient by the treating oncologist.
Other Name: TMZ Drug: Mycophenolate Mofetil 250-2000mg orally twice daily, one week prior to and concurrent with RT and cyclic chemotherapy with temozolomide.
Other Name: MMF Radiation: Radiation Therapy 60 Gy in 30 fractions
Other Name: RT |
- Concentration of mycophenolic acid (MPA) in tumor tissue in Phase 0 participants [ Time Frame: At 1 week ]
The concentration of MPA (the active metabolite of mycophenolate mofetil [MMF]) in tumor tissue, measured by mass spectrometry on a continuous scale after one week of MMF administration.
This measure includes all phase 0 participants.
- Number of recurrent phase 1 participants who experience dose-limiting toxicities (DLTs) at each dose level [ Time Frame: Up to 28 days following completion of MMF + RT (up to ~9 weeks) ]
DLT will be defined based on the rate of drug related grade 3-5 adverse events experienced from the start of treatment with MMF and for up to 4 weeks after completion of MMF + radiation therapy (RT). Assessed using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.
This measure includes only phase 1 participants with recurrent GBM/GS.
- Number of newly diagnosed phase 1 participants who experience dose-limiting toxicities (DLTs) at each dose level -- DLT1 period [ Time Frame: Up to 28 days following completion of MMF + RT + TMZ (up to ~11 weeks) ]
DLT will be defined based on the rate of drug related grade 3-5 adverse events experienced from the start of treatment with MMF and for up to 4 weeks after completion of MMF + RT + TMZ. Assessed using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.
This measure includes only newly diagnosed phase 1 participants.
- Number of newly diagnosed phase 1 participants who experience dose-limiting toxicities (DLTs) at each dose level -- DLT2 period [ Time Frame: During the first 2 cycles (8 weeks) of MMF with adjuvant TMZ (up to ~19 weeks) ]
DLT will be defined based on the rate of drug related grade 3-5 adverse events experienced during the first 2 cycles (8 weeks) of MMF with adjuvant TMZ. (The first cycle of MMF with adjuvant TMZ begins 28 days post-RT.) These will be assessed using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.
This measure includes only newly diagnosed phase 1 participants.
- Concentrations of guanosine triphosphate (GTP) in tumor tissue in Phase 0 participants [ Time Frame: After one week of MMF administration ]
The concentrations of GTP in tumor tissue, measured by mass spectrometry on a continuous scale.
This measure includes all phase 0 participants.
- Adverse events associated with treatment in all Phase 1 Participants [ Time Frame: Up to 28 days following completion of MMF + RT (up to ~9 weeks) ]
Toxicities at each dose level will be tabulated, categorized by grade and attribution.
This measure includes all phase 1 participants.
- Adverse events associated with treatment in newly diagnosed phase 1 participants [ Time Frame: Up to 28 days following completion of MMF with adjuvant temozolomide (up to ~15 months) ]
Toxicities at each dose level will be tabulated, categorized by grade and attribution.
This measure includes only newly diagnosed phase 1 participants.
- Overall Response Rate in phase 1 participants with recurrent GBM/GS [ Time Frame: Until study stops or death; up to approximately 3 years. ]
Determined by modified Response Assessment for Neuro-Oncology (mRANO) criteria. The number and proportion of patients with progressive disease, stable disease, partial and complete response will be calculated for each dose level and overall.
This measure includes only phase 1 participants with recurrent GBM/GS.
- Median Progression Free Survival (PFS) in phase 1 participants with recurrent GBM/GS [ Time Frame: Until study stops or death; up to approximately 3 years. ]
PFS defined as time from date of registration to the date of documented progressive disease, other disease related therapy or death. Determined by mRANO criteria.
This measure includes only phase 1 participants with recurrent GBM/GS.
- Median Freedom from Local Progression (FFLP) in phase 1 participants with recurrent GBM/GS [ Time Frame: Until study stops or death; up to approximately 3 years. ]
FFLP defined as time from date of registration to the date of documented local progressive disease. Determined by mRANO criteria.
This measure includes only phase 1 participants with recurrent GBM/GS.
- Median Overall Survival (OS) in phase 1 participants with recurrent GBM/GS [ Time Frame: Until study stops or death; up to approximately 3 years. ]
OS defined as time from date of registration to date of death or last follow up. Determined by Kaplan Meier method.
This measure includes only phase 1 participants with recurrent GBM/GS.
