Near-Term Commercial Medicines

• Ionis has made important progress in building our commercial and medical affairs organizations led by individuals with deep, relevant expertise across rare and broad diseases.
• With the eplontersen PDUFA date of Dec. 22, 2023 nearing for ATTR polyneuropathy (PN), Ionis is ready to bring this important new medicine to patients along with our partner AstraZeneca, if approved.
  • Eplontersen has the potential to be the treatment of choice, backed by strong efficacy and safety data, a self-administration profile and a strong global alliance with AstraZeneca.
  • Last week, positive Phase 3 NEURO-TTRansform data were published in The Journal of the American Medical Association, and regulatory filings are planned in the EU and other countries this year and next.
  • The Phase 3 CARDIO-TTRansform trial, the largest trial ever conducted in ATTR cardiomyopathy patients, is fully enrolled and expected to read out as early as 1H 2025.
• Olezarsen is poised to be Ionis' first wholly owned independent commercial launch.
  • Last week, Ionis announced positive Phase 3 olezarsen Balance results in FCS, showing statistically significant triglyceride lowering and a substantial reduction in acute pancreatitis events in addition to a favorable safety and tolerability profile. Based on these data, Ionis is planning to file U.S. and EU regulatory applications in early 2024.
  • Phase 3 studies continue for severe hypertriglyceridemia (SHTG), a more prevalent disease affecting more than three million people in the U.S.
  • Henry Ginsburg, M.D., Professor of Medicine, Columbia University, will speak at the event to share his perspectives on the acute need for new treatments to treat people with FCS and SHTG.
• Donidalorsen was recently granted U.S. Orphan Drug Designation.
  • Ionis plans to report Phase 3 results with donidalorsen for prophylactic treatment of hereditary angioedema (HAE) in the first half of 2024. Ionis also plans to report topline data from a second Phase 3 study evaluating switching from currently approved HAE treatments in mid-2024.
  • Two-year results from the Phase 2 open-label-extension trial showed that donidalorsen treatment resulted in a 96% overall sustained mean reduction from baseline in HAE attack rates. These data will be presented at a medical congress later this year.
  • Raffi Tachdjian, M.D., MPH, FAAAAI, FACAAI, Associate Clinical Professor of Medicine and Pediatrics UCLA School of Medicine; Chief, Division of Allergy and Immunology Providence St. John Medical Center will discuss the need for new prophylactic HAE treatments as more than one-third of patients on prophylactic treatment report more than two attacks per month.

Next Wave of Wholly Owned Medicines

• Building on Ionis' proven track record in neurology with two approved medicines, 12 in clinical trials and more than 10 in lead optimization/preclinical development, Ionis is advancing a wholly owned neurology pipeline.  
• The lead independent program, zilganersen for the treatment of Alexander disease, a serious genetic leukodystrophy, is now in Phase 3 development.
• In addition, Ionis will announce today that four new wholly owned medicines in rare pediatric neurological diseases and dementias are planned to enter first-in-patient studies by the end of 2024:
  • ION356 (PLP1), for the treatment of children with Pelizaeus-Merzbacher Disease, a severe leukodystrophy, which recently received Rare Pediatric Disease Designation and Orphan Drug Designation from the U.S. FDA;
  • ION440 for the treatment of children with MeCP2 duplication syndrome, which causes significant developmental delays, impaired motor function and seizures; 
  • ION717, for the treatment of prion disease, which causes fatal dementia, is planned to enter a first-in-patient study in 2023;
  • And, an undisclosed genetic dementia program, which is currently in preclinical development.

Advancing Technologies to Reach More Patients in Need

• Ionis' leading medicinal chemistry platform is enabling technological advances to enhance existing medicine profiles and expand into new tissues and/or therapeutic areas.  
  • Ionis is applying new chemistries such as the Mesyl Phosphoramidate (MsPA) backbone to improve the duration of effect and therapeutic index of investigational medicines.
  • The company is using multiple drug modalities, including antisense (ASO) and small interfering RNA (siRNA), to identify the best potential medicine for a particular target and/or tissue.
  • By leveraging targeted delivery approaches, including Bicycle^® technology via our collaboration with Bicycle Therapeutics, Ionis is developing medicines that have antibody-like selectivity with a low total molecular weight, which allows delivery to skeletal and cardiac muscle.  Progress is also being made in delivering medicines across the blood-brain barrier with systemic dosing.

Clear Path to Unlocking Next-Level Value

• Ionis has a solid financial foundation with a strong balance sheet with ~$2B in cash, and existing substantial and sustained revenue streams.
• Ionis is investing efficiently to bring our near-term medicines to patients.
• Ionis anticipates that revenue growth from multiple medicines as well as ongoing partner and royalty revenue will drive future positive cash flow.
