NCT04737577

Brief Summary

G-SUMIT is a pilot, phase II,randomized controlled trial to evaluate the feasibility of performing a large-scale trial in patients undergoing surgery for first-time diagnosis of high grade glioma (HGG) in a surgically favorable anatomical location to answer the following: Does extending the margin of resection 1 cm beyond visible enhanced volume on MRI result in (a) an increase in overall survival? (b) result in a similar rate of "clinically-significant" neurological worsening during 30 days post surgery and quality of life at 6 and 12 months?

Outcome Measures

Primary Outcomes (1)

  • Enrollment

    The number of patients enrolled and successfully allocated to the intervention versus the control treatment

    Collected at time of randomization, through end of enrollment period (2 years)

Secondary Outcomes (11)

  • Feasibility using eligibility

    Screening/Enrollment

  • Feasibility using proportion of consent

    Screening/Enrollment

  • Feasibility using number of completed visits

    Through study completion, on average 2 years

  • Feasibility using Gross Total Resection

    2 days (+/- 1 day) post surgery

  • Efficacy using overall survival

    6 weeks (+/- 2 weeks), 6 months (+/- 2 weeks) and 12 (+/- 1) months post surgery

  • +6 more secondary outcomes

Study Arms (2)

Supramarginal resection (intervention arm)

EXPERIMENTAL

Planned resection beyond the Gadolinium (GAD)-enhancing region extending to either at least 1 cm into non-enhancing tissue, or the nearest non-enhancing sulcal boundary/ventricle wall if these structures are closer than 1 cm.

Procedure: Supramarginal resection

Conventional (i.e. GTR) resection

OTHER

Planned resection of ≥95% of the GAD-enhancing regions of tumor without expanding the resection beyond this margin.

Procedure: Conventional (i.e. GTR) resection

Interventions

Tissue removal beyond the GAD-enhancing region extending to either at least 1 cm into non-enhancing tissue, or the nearest non-enhancing sulcal boundary/ventricle wall if these structures are closer than 1 cm.

Supramarginal resection (intervention arm)

Planned resection of ≥95% of the GAD-enhancing regions of tumor without expanding the resection beyond this margin.

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Radiographic evidence of a GAD-enhancing intra-axial tumor consistent with HGG;
  • Age ≥18 ≤ 85 years;
  • Karnofsky Performance Score ≥ 60;
  • Location of tumor in a safe anatomical location and
  • Patient or substitute decision maker (SDM) able to understand and consent to study participation.

You may not qualify if:

  • Multi-focal tumor, gliomatosis cerebri (≥3 lobes of the brain affected), tumors crossing the midline, or leptomeningeal enhancement;
  • Previous craniotomy for tumor excision (stereotactic biopsy is permitted);
  • Known metastatic cancer;
  • Uncorrectable coagulopathy;
  • Unable to obtain GAD-enhanced brain MRI.
