Ionis pharmaceuticals receives fast-track designation from U.S. Food and drug administration (FDA) for olezarsen in Familial chylomicronemia syndrome (FCS) treatment. Olezarsen (formerly IONIS-APOCIII-LRx) is an investigational LICA medicine that inhibits apoC-III production in patients who are at risk of disease due to high triglyceride levels.

Diffuse intrinsic pontine glioma (DIPG) is a lethal malignant pediatric tumour that spreads throughout the pons. Pediatric gliomas with a K27M mutation in histone H3 with a diffuse growth pattern in a midline location are referred to as diffuse midline glioma, H3 K27M mutant; this designation is inclusive of DIPG cases bearing the K27M mutation. This devastating disease has a median age of 6-7 years at diagnosis and is rarely detected in adults. Given its eloquent location, current treatment options are limited, and the prognosis is dismal—with less than 10% of patients surviving beyond two years from the time of diagnosis. DIPGs account for 80% of all paediatric brain tumours in the brainstem. These tumours share histological characteristics with anaplastic astrocytomas (grade III) or glioblastomas (GBM) (grade IV. Brainstem gliomas affect approximately 350 to 450 children in the United States annually and are the major cause of death in children with brain tumours. The most common of these is DIPG comprising 80% of the cases.
- DIGP incidence is 1 to 2 cases per 100,000 population, with a peak incidence of 6-9 years and slightly higher among males.
