Clinical Trial Summary

An Open-Label, Multi-Center Study to Assess the Safety and Pharmacokinetics of BRCX014 Combined with Standard-of-Care Treatment in Subjects with Glioblastoma

Description:

Several studies have shown a possible anti-tumor role for cannabinoids by modulating cell signaling pathways, inhibiting angiogenesis, inducing apoptosis, and overcoming chemotherapy resistance. The investigators seek to demonstrate the safety profile of BRCX014, a cannabinoid formulation, when given to glioblastoma patients in conjunction with standard-of-care therapy.

Intervention

Drug:
• Temozolomide
Standard-of-care chemotherapy for patients with glioblastoma includes concurrent radiation therapy (2 Gy per day for a total of 60 Gy) and temozolomide (75 mg per square meter of body- surface area per day, seven days per week from the first to the last day of radiotherapy), followed by six cycles of adjuvant temozolomide (150 to 200 mg per square meter for five days during each 28-day cycle).

Device:
• Optune
Standard-of-care treatment for glioblastoma includes alternating electric-field therapy, or Optune, as a Category 1 treatment in conjunction with temozolomide after maximal safe resection and completion of radiation therapy.
