Current Primary Outcome Measures  ICMJE
 (submitted: May 11, 2020)
  • Incidents of Adverse Events during the subjects are taking OKN-007 with Temozolomide [ Time Frame: Through study completion up to 24 months ]
    Evaluate incidents of Adverse Events during the subjects are taking OKN-007 with Temozolomide. Adverse events will be graded according to Common Terminology Criteria for Adverse Events (CTCAE, version 5.0).
  • Number of subjects with decreased neurological function [ Time Frame: Change from baseline at Day 1 of each 28 day cycle ]
    Neurologic function assessed by Neurologic Assessment in Neuro-Oncology (NANO) scale. The NANO Scale evaluates 9 major domains of neurologic function, with each domain being scored on a range from 0 (no deficits) to 2 or 3 (maximum deficits).
  • Number of subjects with decreased performance [ Time Frame: Change from baseline at Day 1 of each 28 day cycle ]
    Number of participants with decreased performance assessed by Eastern Oncology Cooperative Group (ECOG) scale. Minimum 0 (normal function) and maximum 4 (maximum disability).
  • Overall Survival (OS) rate [ Time Frame: 6 months ]
    Proportion of subjects who are alive after six months of starting treatment. OS is defined as the time from first treatment dose until date of death due to any cause.

  • Progression Free Survival (PFS) rate [ Time Frame: 6 months ]
    Proportion of subjects who are alive and progression free after six months of starting treatment. PFS is defined as the time from first treatment dose until objective tumor progression on the RANO criteria or death.
  • Cmax of OKN-007 in blood plasma [ Time Frame: Day 1 and Day 5 in Cycle 1 and 2 (28 Day Cycle) ]
    The sample will be collected at 10 time points during 24 hours after OKN-007 administration.
  • AUC of OKN-007 in blood plasma [ Time Frame: Day 1 and Day 5 in Cycle 1 and 2 (28 Day Cycle) ]
    The sample will be collected at 10 time points during 24 hours after OKN-007 administration.
  • Tmax of OKN-007 in blood plasma [ Time Frame: Day 1 and Day 5 in Cycle 1 and 2 (28 Day Cycle) ]
    The sample will be collected at 10 time points during 24 hours after OKN-007 administration.
  • Cmax of Temozolomide in blood plasma [ Time Frame: Day 1 and Day 5 in Cycle 1 and 2 (28 Day Cycle) ]
    The sample will be collected at 8 time points during 24 hours after Temozolomide administration.
  • AUC of Temozolomide in blood plasma [ Time Frame: Day 1 and Day 5 in Cycle 1 and 2 (28 Day Cycle) ]
    The sample will be collected at 8 time points during 24 hours after Temozolomide administration.
  • Tmax of Temozolomide in blood plasma [ Time Frame: Day 1 and Day 5 in Cycle 1 and 2 (28 Day Cycle) ]
    The sample will be collected at 8 time points during 24 hours after Temozolomide administration.

Official Title  ICMJE A Phase II Open-label Study Investigating the Efficacy, Safety and Pharmacokinetic Properties of OKN-007 Combined With Temozolomide in Patients With Recurrent Glioblastoma
Brief Summary This is a phase II open-label study investigating the efficacy, safety and pharmacokinetic(PK) properties of OKN-007 combined with temozolomide(TMZ) in patients with recurrent glioblastoma(GBM). All patients will have been previously treated with the standard-of-care treatment which includes surgical resection, radiation and chemotherapy, and in some cases treatment for recurrent disease. Patients with unequivocal recurrence (first or greater) established by MRI and meeting inclusion and exclusion criteria, will be eligible for OKN-007 treatment on this protocol.
