Dr. Sampson is a recognized leader in the surgical resection and experimental treatment of complex brain tumors. His clinical practice is focused on treating patients with both benign and malignant brain tumors, while his research laboratory is actively investigating immunotherapy and new modalities of precision drug delivery to brain tumor tissue while avoiding healthy tissue. He is a neurosurgeon-scientist who develops novel drugs for patients with brain tumors and focuses on the development, translation, and mechanistic understanding of immunotherapies. His research led to the development of a vaccine against a common mutation in brain tumors that was given Breakthrough Therapy Designation by the FDA after it was shown to extend survival in patients with glioblastoma multiforme, the most lethal form of brain cancer. Dr. Sampson has published more than 200 peer-reviewed articles in high impact journals such as Nature, JAMA, and the Proceedings of the National Academy of Sciences, and has been an editorial board member for all major journals in the field.

About Oncotelic’s Lead Product Candidate, OT-101

High-grade gliomas (HGG) are characterized by a T-cell exhaustion signature and pronounced T-cell hyporesponsiveness of their tumor microenvironment (TME).  Transforming growth factor beta 2 (TGFB2) has been implicated as a key contributor to the immunosuppressive landscape of the TME in HGG.  OT-101, a TGFB2-specific first-in-class RNA therapeutic designed to abrogate the immunosuppressive actions of TGFB2.  In a completed Phase 2 clinical study, OT-101 exhibited clinically meaningful single-agent activity and induces durable complete and partial responses in recurrent and refractory adult HGG patients, including young adults with GBM or AA.
