On track to achieve 2024 P&L financial guidance; increased 2024 cash guidance

CARLSBAD, Calif., Nov. 6, 2024 /PRNewswire/ -- Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) (the "Company") today reported financial results for the third quarter of 2024.

"Today, we stand on the cusp of a new era for Ionis, with our first co-commercialization launch proceeding well with WAINUA, our first planned independent launch fast approaching and continued strong progress across our rich pipeline. With an upcoming December FDA action date, we are ready to independently bring olezarsen to people with familial chylomicronemia syndrome, a serious rare disease with no approved treatments in the U.S. We are similarly well positioned for our second independent launch for donidalorsen, which we believe could become a preferred treatment choice for people with hereditary angioedema, with an FDA action date of August 21, 2025," said Brett P. Monia, Ph.D., chief executive officer of Ionis. "In parallel, we are making great progress across the rest of our rich Phase 3 pipeline. We expect Phase 3 results supporting olezarsen's second indication in severe hypertriglyceridemia and pelacarsen in Lp(a)-driven cardiovascular disease next year, as well as Phase 3 results supporting eplontersen's second indication in ATTR cardiomyopathy in the second half of 2026. We are also advancing our next wave of potentially transformational wholly owned medicines, including ION582 for Angelman syndrome, which we expect to enter Phase 3 development in the first half of next year following our positive end of Phase 2 discussion with the FDA. Our recent achievements, together with our advancing and expanding pipeline, position Ionis to deliver on our goal to bring a steady cadence of transformational medicines to people with serious diseases."

Third Quarter 2024 Financial Results

"This year has been marked by strong delivery on our pipeline and business goals, which position Ionis to deliver on our vision of bringing a steady cadence of innovative medicines to patients in need. Fully realizing these significant opportunities requires substantial investment. As a result, we recently executed an equity offering that extends our cash runway, enabling us to continue to invest in the numerous attractive opportunities ahead of us, including our near-term commercial launches with multi-billion-dollar revenue potential and our rich late and mid-stage pipeline," said Elizabeth L. Hougen, chief financial officer of Ionis. "Looking beyond this year, we will continue to invest in go-to-market preparations for our planned olezarsen and donidalorsen launches. Additionally, with our increased confidence in the potential of WAINUA and olezarsen to address broader patient populations, we plan to scale our capabilities in line with the significant potential of these important medicines. At the same time, we are investing in our next wave of medicines, including pre-commercialization activities and Phase 3 development for ION582 for Angelman syndrome and zilganersen for Alexander disease. We expect our investments today will position Ionis for sustainable growth for years to come."

Revenue

Ionis' revenue was comprised of the following:

Commercial revenue for the three and nine months ended September 30, 2024 included a new source of royalty revenue with the launch of WAINUA in the U.S. in late January 2024. Ionis' commercial revenue for the three and nine months ended September 30, 2024 and 2023 also included royalties from the net sales of QALSODY, which Biogen launched in the U.S. in the second quarter of 2023 and in the EU in the second quarter of 2024. SPINRAZA product sales for the three months ended September 30, 2024 compared to the same period last year increased slightly in the U.S. and decreased outside of the U.S. primarily due to an annual order from a single country that did not recur in 2024.

R&D revenue was relatively consistent for the three months ended September 30, 2024 compared to the same period last year. R&D revenue increased for the nine months ended September 30, 2024 compared to the same period last year primarily due to the amortization of upfront payments from the new collaborations with Roche and Novartis that Ionis entered into during the second half of last year. In addition, license fees increased year over year as a result of new collaborations Ionis entered into during the second quarter of 2024, including the expanded donidalorsen licensing agreement with Otsuka, which now includes the Asia-Pacific region in addition to Europe. These increases were partially offset by the decrease in WAINUA joint development revenue, which decreased as development activities relating to ATTRv-PN wound down with the launch of WAINUA for this indication.

Operating Expenses

Ionis' operating expenses, excluding one-time costs associated with a lease exit in the third quarter of 2023, increased for the three and nine months ended September 30, 2024 compared to the same periods in 2023, consistent with expectations. SG&A expenses increased year over year primarily due to the launch of WAINUA in the U.S. and launch preparation activities for olezarsen and donidalorsen, including establishing the field team for olezarsen in the second quarter of 2024. R&D expenses were essentially flat for the three and nine months ended September 30, 2024 compared to the same periods last year as several late-stage studies have ended.

Balance Sheet

As of September 30, 2024, Ionis' cash, cash equivalents and short-term investments increased to $2.5 billion compared to $2.3 billion at December 31, 2023. In September 2024, Ionis issued 11.5 million shares of its common stock at a public offering price of $43.50 per share that generated gross proceeds of $500 million, before deducting underwriting discounts and commissions and other offering expenses payable by Ionis. The Company plans to continue deploying its capital resources toward growth opportunities, and projects to end 2024 with $2.2 billion in cash, cash equivalents and short-term investments. Ionis' working capital also increased over the same period primarily due to the Company's higher cash and short-term investments balance. As a result of Ionis' advancing pipeline that has delivered several positive data readouts, Ionis expects to make increased investments in the years ahead with the goal to realize the value of these opportunities, with a focus on its wholly owned late-stage and next wave of innovative medicines.
