Glioblastoma multiforme (GBM) is an incurable brain tumor characterized by aggressive progression and frequent relapses. The average life expectancy for GBM patients is 9 months, with only 3 to 5 percent of patients surviving longer than 3 years. Although multiple chemotherapies and immunotherapies are available to potentially prolong the life of patients with GBM, the prognosis remains extremely poor. The two biggest challenges in treating glioblastoma multiforme are eliminating dormant, cancerous glial cells left behind after surgery and transporting therapeutic molecules across the highly selective blood-brain barrier. The constantly evolving field of nanomedicine has shown great promise in addressing these challenges. Antibody-drug conjugates, or ADCs, consist of a combination of a monoclonal antibody (mAb) covalently linked to a cytotoxic payload molecule. When used to inhibit cancer progression, the antibody specifically binds to antigens overexpressed on the surface of tumors, selectively destroying cancer cells and preserving healthy tissue. While ADCs have been approved to treat breast cancer, there is minimal research on how they can be used to safely combat GBM. In this paper, we discuss the design of a novel antibody-drug conjugate targeting IL13Rɑ2 and suggest a method of delivery specific to GBM.
