Since Neuradiab® has shown promising efficacy in patients with recurrent disease with acceptable risk-benefit ratio, and since there is no substantial survival benefit from currently available agents used to treat this patient population, Neuradiab® is being proposed as an experimental alternative to recurrent GBM patients under a Single-Center Phase II Trial. Recurrent GBM is a serious and immediately life-threatening disease, for which there is no comparable or satisfactory alternative drug or other therapy available to treat that stage of the disease. Overall, survival data indicate a need for more effective treatments for recurrent GBM.
