Descriptive Information
Brief Title  ICMJE A Study to Evaluate the Safety of 2-OHOA Added to Standard of Care in Newly-diagnosed Glioblastoma Patients
Official Title  ICMJE A Phase 1B Study of the Safety of 2-Hydroxyoleic Acid Sodium Salt (2-OHOA) Administered Orally in Combination With Temozolomide (TMZ) and Radiation Therapy or With TMZ Alone in the First Line Treatment of Subjects With Glioblastoma
Brief Summary The purpose of this study is to determine the safety and tolerability of 2-OHOA added to first-line treatment for subjects with newly diagnosed glioblastoma (GBM), and to determine the highest safe dose of 2-OHOA administered orally when added to the concurrent phase of treatment with temozolomide (TMZ) and radiation therapy (RT) or when added to the maintenance phase of treatment with TMZ (once TMZ 200 g/m2/day is started).
Detailed Description

This is a Phase IB, open-label, dose-finding study. A de-escalation process has been selected for the study with a 3+3 design to establish the Maximum Tolerated Dose (MTD).

The first group of 3 subjects (within each arm), where all 3 subjects may be started at the same time, will receive 2-OHOA at the starting dose of 12 g/day (4 g tid). If 0-1 Dose-Limiting Toxicities (DLTs) in the first 3 patients, then a new cohort with 3 more patients is started at 12 g/day (4 g tid). If 2 or more patients out of 3 or 6 patients experience DLT(s) the dose is deescalated.

De-escalation doses are from 12 g/day (4 g tid) to 8 g/day (4 g bid) and from 8 g/day (4 g bid) to 4 g/day (4 g od). This procedure must be applied to the two arms of the study described below. Both arms will be independent, and will run in parallel, therefore none of the patients from Arm 1 may enter Arm 2.

  • Drug: 2-OHOA
    Arm 1: Daily for 6 weeks. Arm 2: daily, two 28-day cycles
    Other Name: 2-Hydroxyoleic acid, sodium salt, 2OHOA
  • Radiation: RT
    In Arm 1: Fractionated focal irradiation of 1.8-2 Gy/fraction/day, 5 days/week, 6 weeks. Total dose up to 60 Gy
    Other Name: radiotherapy
  • Drug: TMZ
    Arm 1: 75 mg/m2/day, daily, 6 weeks Arm 2: 200 mg/m2/day, daily the first 5 days of two 28-day cycles (in case of toxicity, TMZ dose may be reduced to 150 mg/m2/day at Cycle 3 to allow for recovery)
    Other Name: temozolomide
Study Arms  ICMJE
  • Experimental: Arm 1 (chemoradiation phase)

    Radiotherapy (RT) + temozolomide (TMZ) + 2-OHOA (during Concurrent phase - duration 6 weeks)*:

    2-OHOA will be initiated at the start of the concurrent phase and will be administered on a continuous daily basis together with TMZ and RT for 6 weeks at the selected dose, either 12 g/day (4 g tid), 8 g/day (4 g bid) or 4 g/day (4 g od).

    RT will be administered only during the concurrent phase, consisting of fractionated focal irradiation administered using 1.8- 2 Gy/fraction, daily for 5 days/week for 6 weeks, for a total dose of up to 60 Gy.

    TMZ will be administered during the concurrent phase at a starting dose of 75 mg/m2/day given daily for 6 weeks.

    * One extra week may be allowed.

    • Drug: 2-OHOA
    • Radiation: RT
    • Drug: TMZ
  • Experimental: Arm 2 (maintenance phase)

    TMZ + 2-OHOA (during Maintenance phase with TMZ 200 mg/m2/day at Cycle 2 - duration 8 weeks):

    2-OHOA will be initiated on day 2 of Cycle 2 of the maintenance phase, when TMZ 200 mg/m2/day is given and administered on a continuous basis for two 28-day cycles. 2-OHOA will be administered at the selected dose, either 12 g/day (4 g tid), 8 g/day (4 g bid) or 4 g/day (4 g od).

    TMZ will be administered at 200 mg/m2/day given daily the first 5 days for two 28-day cycles (if no toxicity is seen). In case of toxicity, TMZ dose may be reduced to 150 mg/m2/day at Cycle 3 to allow for recovery.

    Both arms will be followed by a 4-week safety follow-up

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Glioblastoma (GBM) according to 2016 World Health Organization (WHO) Classification.
  2. Must have had a partial or complete surgical resection of the Grade 4 astrocytic tumor.
  3. Subjects in Arm 1 must have had no previous treatment except surgery (ie, no previous RT, local CT, or systemic therapy). Subjects must meet certain other eligibility requirements.
  4. Subjects in Arm 2 must have completed a standard first line regimen of concurrent TMZ and RT for newly diagnosed GBM patients, followed by a rest phase, and have not had any other previous CT except surgery (including any other regimens of RT and local or systemic CT). Progression and/or pseudoprogression should have been ruled out before starting Arm 2 as per usual clinical practice, with correct laboratory results (absolute neutrophile count ≥1.5 x 109/L, platelet count ≥ 100 x 109/L, non-haematological toxicity grade ≤ 2) at screening.
