Monia, Ph.D., chief executive officer, Ionis. \u201cFrank\u2019s profound contributions include pioneering the use of antisense medicines in neurological disease. He led the discovery and development of the first approved medicines for spinal muscular atrophy and a genetic form of amyotrophic lateral sclerosis, which have transformed the lives of thousands of people. We are deeply grateful for Frank\u2019s scientific leadership and unwavering dedication to the patients and communities that are counting on us.\u201d<\/p>\n<p>Dr. Bennett joined Ionis as a founding scientist in 1989 and has pioneered the use of antisense oligonucleotides (ASOs) across multiple therapeutic disciplines. His research has focused on the basic mechanisms of ASOs, including pharmacokinetics, medicinal chemistry and cellular uptake. Notably, Dr. Bennett demonstrated that antisense drugs could spread broadly throughout the central nervous system when introduced directly into the cerebral spinal fluid.<\/p>\n<p>As head of Ionis\u2019 research programs, Dr. Bennett contributed to the discovery of more than fifty drug candidates, with seven receiving regulatory approval worldwide. He spearheaded the discovery and development of several Ionis medicines for neurological diseases, including SPINRAZA<sup>\u00ae<\/sup> (nusinersen), the first approved treatment for spinal muscular atrophy (SMA), and QALSODY<sup>\u00ae<\/sup> (tofersen), the first approved treatment for a genetic form of amyotrophic lateral sclerosis (ALS). In addition, Dr. Bennett led the discovery of several clinical-stage Ionis medicines for neurological diseases, including programs targeting additional genetic forms of ALS, Parkinson&#8217;s disease, prion disease, Angelman syndrome, MECP2 duplication syndrome, as well as zilganersen, an investigational medicine for Alexander\u2019s disease currently under review with the U.S. Food and Drug Administration. His work also extended to non-neurologic conditions, including bepirovirsen, an investigational medicine for chronic hepatitis B (CHB) currently under regulatory review with several global health authorities.<\/p>\n<p>Dr. Bennett\u2019s distinguished career has been recognized with several prestigious awards, including the 2019 Breakthrough Prize in Life Sciences in recognition of his work developing SPINRAZA, the inaugural 2019 Healey Center International Prize for Innovation in ALS, the 2021 Lifetime Achievement Award from the Oligonucleotide Therapeutics Society, the 2021 Gabbay Award and the 2023 Rainwater Prize for Outstanding Innovation in Neurodegenerative Disease Research. He has authored more than 240 peer-reviewed manuscripts and holds more than 200 issued U.S. patents.<\/p>\n<p>Dr. Bennett will serve as a strategic consultant for a period after his retirement to support the transition. His responsibilities will be assumed by Eric Swayze, Ph.D., executive vice president, head of research.<\/p>\n<p><b>About Ionis Pharmaceuticals, Inc.<\/b><\/p>\n<p>For more than three decades, Ionis has invented medicines that bring better futures to people with serious diseases.
