Ionis reports third quarter 2023 financial results

Olezarsen Phase 3 data showed significant triglyceride lowering, substantial reductions in acute pancreatitis attacks and favorable safety and tolerability in patients with FCS; on track for regulatory filings in early 2024

Eplontersen marketing applications accepted for review in the EU and Canada; potential U.S. approval in December 2023

On track to achieve 2023 financial guidance

CARLSBAD, Calif., Nov. 2, 2023 /PRNewswire/ -- Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) (the "Company"), today reported financial results for the third quarter of 2023.

"We continue to successfully execute on our strategy to deliver a steady cadence of potentially transformational medicines to patients," said Brett P. Monia, Ph.D., chief executive officer of Ionis. "Eplontersen is on track for its first potential approval in the U.S. and is under regulatory review in the EU and Canada. We believe the positive efficacy and safety data coupled with an attractive self-administration dosing profile positions eplontersen to be the preferred therapy in the largely underserved hereditary ATTR polyneuropathy population. We reported positive data from the olezarsen Phase 3 Balance study in patients with familial chylomicronemia syndrome, showing statistically significant triglyceride lowering, substantial reductions in acute pancreatitis attacks and favorable safety and tolerability, positioning olezarsen to be our first independent commercial launch. We also made additional progress across our wholly owned and partnered pipeline, and further expanded our rich Phase 3 pipeline with the advance of zilganersen for patients with Alexander disease into Phase 3 development. Looking ahead, we expect to continue our positive momentum with the potential approval and launch of eplontersen and the Phase 3 data readout of donidalorsen in hereditary angioedema."

Third Quarter 2023 Financial Results

"Our year-to-date financial results keep us on track to achieve our 2023 guidance as we execute on a strategy to unlock next-level value," said Elizabeth L. Hougen, chief financial officer of Ionis. "Our strong financial foundation includes more than $2B in cash, significant royalty revenue with SPINRAZA, and substantial and sustained R&D revenue from multiple partners. We are well positioned to continue investing in our key priorities to drive future positive cash flow, including advancing our go-to-market activities, growing our wholly owned pipeline and optimizing new cutting-edge technologies for future medicines. We look forward to the potential U.S. eplontersen ATTRv-PN approval next month followed closely by launch. Together with our partner, AstraZeneca, we believe we are well positioned to identify new patients to further grow the market and become the treatment of choice for this population that remains largely underserved by current therapies."

Revenue

Ionis' revenue was comprised of the following:

Commercial revenue for the three and nine months ended September 30, 2023 included $67 million and $179 million from SPINRAZA royalties, respectively, which were essentially flat compared to the same periods last year reflecting SPINRAZA's resilience against emerging competition. Ionis' commercial revenue in the three and nine months ended September 30, 2023 also included royalties from the U.S. launch of QALSODY.

R&D revenue decreased for the three months ended September 30, 2023 and increased for the nine months ended September 30, 2023 compared to the same periods last year due to the timing of certain partner payments, including the $35 million license fee for IONIS-FB-L_Rx that Ionis earned from Roche in the three months ended September 30, 2022.

Operating Expenses

Ionis' operating expenses increased in the three and nine months ended September 30, 2023 compared to the same periods in 2022, consistent with expectations. As Ionis advanced its robust pipeline, study costs increased compared to the same periods in 2022 as most of the Company's Phase 3 studies are either fully enrolled or approaching full enrollment, resulting in higher R&D expenses year over year. Ionis' SG&A expenses also increased year over year primarily due to launch preparation activities for eplontersen, olezarsen and donidalorsen.

Balance Sheet

As of September 30, 2023, Ionis' cash, cash equivalents and short-term investments increased to $2.2 billion compared to $2.0 billion at December 31, 2022 primarily due to the $500 million Ionis received from Royalty Pharma in January 2023. Ionis' working capital also increased over the same period primarily due to the Company's higher cash and short-term investments balance. In the first quarter of 2023, the Company recorded a long-term liability for future royalties due to Royalty Pharma. In June 2023, Ionis issued $575 million of senior convertible notes due in June 2028 with an interest rate of 1.75%. The Company used the majority of the proceeds to repurchase $504 million of its 0.125% convertible notes.
