Glioblastoma Treatment with Irradiation and Olaptesed Pegol (NOX-A12) in MGMT Unmethylated Patients (GLORIA)
(ref: NCT04121455)
Status: active, not recruiting

Glioblastoma multiforme (GBM) is one of the deadliest and most aggressive forms of brain cancer. Patients with this devastating orphan disease are faced with extremely poor prognosis and a staggering 95% of them will not survive beyond 5 years. The standard of care – a combination treatment, including surgery, radiotherapy and chemotherapy – unfortunately is not curative. Moreover, not all patients benefit clinically from chemotherapy, which thus provides limited efficacy while increasing side-effect burden on patients. There is a huge unmet need for an effective approach to treat GBM that prevents tumor recurrence. Our approach is built on research and data suggesting that tumor microenvironment (TME) plays a critical role in how effective anti-cancer therapies are at fighting the disease.

GLORIA is Phase 1/2 study in glioblastoma (brain cancer) patients resistant to standard chemotherapy (unmethylated MGMT promoter) consisting of a dose-escalation part with NOX-A12 plus radiotherapy and three additional arms combining NOX-A12 with radiotherapy plus bevacizumab (VEGF inhibitor) or pembrolizumab (PD-1 inhibitor), or NOX-A12 plus radiotherapy in patients with complete tumor resection.

Results in NOX-A12 + RT + anti-VEGF combination generated and reported to date from a 6-patient cohort2,3:

  • 19.9 months median Overall Survival (mOS) 
  • 10-fold improvement in 21-month survival vs. standard of care (50% vs. 5%) 
  • 100% of patients attained radiographic partial responses (PR) of the tumor lesions (>50% shrinkage).
  • 83% of patients achieved durable (>6 months) partial responses by mRANO criteria (modified Response Assessment in Neuro-Oncology), which takes into account radiographic response as well as other factors such as clinical condition of the patient.
  • 50% of patients achieved >99% tumor size reduction incl. 1 complete response where the tumor disappeared completely and was no longer detectable by MRI
  • All mRANO partial responders maintained stable neurologic function as assessed by the NANO (Neurologic Assessment in Neuro-Oncology). Other quality of life measurements were stable or improved in the majority of patients with a median follow-up of 7.9 months.
  • The triple combination of NOX-A12, radiotherapy and bevacizumab was well tolerated and safe. No dose-limiting toxicities were observed.

GLORIA Overall Survival at 21 months:
NOX-A12 Combinations Improve Survival in Chemotherapy-Resistant Incompletely Resected Glioblastoma Patients

Therapies with NOX-A12 indicate promising and exciting efficacy, and potential for clinical benefit over standard of care.
