> Otsuka to leverage strong commercial infrastructure and rare disease experience to reach European HAE patients

> Ionis plans to independently bring donidalorsen to U.S. patients if approved

> Donidalorsen Phase 3 results expected in the first half of 2024


Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today announced that it has entered into a license agreement with Otsuka Pharmaceutical Co., Ltd. (Otsuka) under which Otsuka obtains exclusive rights in Europe to commercialize donidalorsen, an investigational prophylactic treatment for hereditary angioedema (HAE). Ionis will maintain responsibility for the non-clinical and clinical development of donidalorsen, and Otsuka will be responsible for European regulatory filings and commercialization.

Ionis plans to independently launch donidalorsen in the U.S. if approved, as part of the company's strategy to deliver a steady flow of wholly owned medicines to patients.

"We are excited to collaborate with Otsuka given their proven results in bringing rare disease medicines to patients in Europe," said Brett P. Monia, Ph.D., Ionis' chief executive officer. "This agreement is aligned with our strategy to initially focus our commercialization efforts on the U.S. market. We are encouraged by the strong product profile of donidalorsen to date and look forward to reporting pivotal topline Phase 3 donidalorsen results in HAE in the first half of next year."

Otsuka brings expertise in delivering rare disease medicines to patients, a robust commercial infrastructure, and deep knowledge of regional and local regulations across European countries. As part of the agreement, Ionis will receive a $65 million upfront payment and milestone payments based on achievement of regulatory and sales targets. Ionis is also eligible to earn tiered royalties ranging from 20 to 30 percent (based on aggregate annual net sales).

Makoto Inoue, president and representative director of Otsuka Pharmaceutical Co., Ltd. commented, "Otsuka has developed drugs in Europe for rare diseases such as autosomal dominant polycystic kidney disease (ADPKD). Through this collaboration with Ionis, a leader in RNA-targeted therapy, if regulatory approval is received, we look forward to bringing donidalorsen to patients in Europe to address the unmet medical needs of patients with HAE."

Ionis recently reported two-year results from the Phase 2 open-label extension (OLE) trial showing that donidalorsen treatment resulted in a 96% overall sustained mean reduction from baseline in HAE attack rates and was recently granted Orphan Drug Designation in the U.S.

Injection site (IS) discoloration and IS reaction were the only study drug-related treatment-emergent adverse events (TEAEs) reported in more than one patient (n=2, 11.8% each). No serious adverse events were reported in the OLE study, and no TEAEs led to study discontinuation. The company plans to report Phase 3 results with donidalorsen for prophylactic treatment of HAE in the first half of 2024.


About Hereditary Angioedema (HAE)

HAE is a rare and life-threatening genetic disease characterized by unpredictable and frequently severe swelling of the skin, gastrointestinal (GI) tract, upper respiratory system, face, and throat, which can be life-threatening.1-5 HAE is estimated to affect more than 20,000 patients in the U.S. and Europe.6 In the U.S., doctors frequently use prophylactic treatment approaches to prevent and reduce the severity of HAE attacks in patients.


About Donidalorsen

Donidalorsen is an investigational LIgand-Conjugated Antisense (LICA) medicine designed to target the prekallikrein, or PKK, pathway. PKK plays an important role in activating inflammatory mediators associated with acute attacks of hereditary angioedema (HAE). By reducing the production of PKK, donidalorsen could be an effective prophylactic approach to preventing HAE attacks.
