Please also include an estimate of the number of people in the United States currently diagnosed with glioblastoma (“GBM”) , since you intend to rely on such information to receive orphan drug designation . Lastly, please provide a brief explanation of how orphan drug designation for GBM may affect the approval and marketing of a product candidate for HGG.
