Outcome Measures

Primary Outcomes (4)

  • Concentration of mycophenolic acid (MPA) in tumor tissue in Phase 0 participants

    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.

    At 1 week

  • Number of recurrent phase 1 participants who experience dose-limiting toxicities (DLTs) at each dose level

    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.

    Up to 28 days following completion of MMF + RT (up to ~9 weeks)

  • Number of newly diagnosed phase 1 participants who experience dose-limiting toxicities (DLTs) at each dose level -- DLT1 period

    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.

    Up to 28 days following completion of MMF + RT + TMZ (up to ~11 weeks)

  • Number of newly diagnosed phase 1 participants who experience dose-limiting toxicities (DLTs) at each dose level -- DLT2 period

    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.

    During the first 2 cycles (8 weeks) of MMF with adjuvant TMZ (up to ~19 weeks)

Secondary Outcomes (7)

  • Concentrations of guanosine triphosphate (GTP) in tumor tissue in Phase 0 participants

    After one week of MMF administration

  • Adverse events associated with treatment in all Phase 1 Participants

    Up to 28 days following completion of MMF + RT (up to ~9 weeks)

  • Adverse events associated with treatment in newly diagnosed phase 1 participants

    Up to 28 days following completion of MMF with adjuvant temozolomide (up to ~15 months)

  • Overall Response Rate in phase 1 participants with recurrent GBM/GS

    Until study stops or death; up to approximately 3 years.

  • Median Progression Free Survival (PFS) in phase 1 participants with recurrent GBM/GS

    Until study stops or death; up to approximately 3 years.

  • +2 more secondary outcomes

Study Arms (3)

Phase 0 - Recurrent glioblastoma (GBM) / gliosarcoma (GS)

EXPERIMENTAL

Mycophenolate mofetil

Drug: Mycophenolate MofetilProcedure: Re-resection (as part of standard of care)

Phase 1 - Recurrent GBM / GS

EXPERIMENTAL

Mycophenolate mofetil; radiation therapy

Radiation: Radiation TherapyDrug: Mycophenolate Mofetil

Phase 1 - Newly Diagnosed GBM / GS

EXPERIMENTAL

Mycophenolate mofetil; radiation therapy; temozolomide

Drug: TemozolomideDrug: Mycophenolate MofetilRadiation: Radiation Therapy

Interventions

500-2000mg orally twice daily, one week prior to re-resection (2 participants at each of 4 dose levels: 500mg, 1000mg, 1500mg and 2000mg)

Also known as: MMF
Phase 0 - Recurrent glioblastoma (GBM) / gliosarcoma (GS)

40.5 Gy in 15 fractions

Also known as: RT
Phase 1 - Recurrent GBM / GS

Re-resection or biopsy of tumor as part of standard of care

Phase 0 - Recurrent glioblastoma (GBM) / gliosarcoma (GS)

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.

Also known as: TMZ
Phase 1 - Newly Diagnosed GBM / GS
