Glioblastoma Multiforme (GBM) is the most common and most lethal form of brain cancer. GBM affects an estimated 12,000 new patients each year in the US alone1. The median survival in newly diagnosed patients with the best available treatments is 20.5 months2.
After diagnosis, today's standard treatment includes surgical resection of the tumor followed by radiotherapy and chemotherapy with temozolomide (TMZ). Nearly all GBM patients relapse following first-line treatment, and those patients have a one-year survival rate of approximately 25%. The average five-year survival rate is less than 3%3.
VAL-083 for the Treatment of Glioblastoma Multiforme
New Hope Against Unmethylated-MGMT GBM
Based on historical data and our own scientific and clinical research, we believe VAL-083 can potentially offer physicians and patients a new paradigm in the treatment of GBM.
The DNA damage inflicted on cancer cells by TMZ, the current standard of care against GBM, is repaired by the DNA repair enzyme O6-DNA methylguanine methyltransferase (MGMT). High expression of MGMT is strongly correlated with resistance to TMZ and poor patient outcomes4.
We have demonstrated that VAL-083 can overcome MGMT-related treatment resistance and has a more potent activity than TMZ against human brain tumor cells. This suggests that VAL-083 has the potential to establish a new standard of care for MGMT-unmethylated patients unlikely to benefit from TMZ.
VAL-083 has been granted orphan drug designations for the treatment of GBM from both the FDA and EMA. VAL-083 has also been granted orphan drug designations for the treatment of medulloblastoma and ovarian cancer from the FDA. In addition, the FDA also granted a fast track designations for VAL-083 in recurrent GBM.
Current Clinical Trials
We are currently conducting clinical trials for VAL-083. Because the mechanism of action of VAL-083 is unique, we are offering a new hope for patients where other treatments may not be effective.
