CARLSBAD, Calif. – Ionis Pharmaceuticals, Inc. (NASDAQ:IONS) today shared encouraging topline results from the HALOS Phase 1/2a study of its drug ION582, designed to treat Angelman syndrome. The drug demonstrated safety and tolerability, as well as consistent functional improvements in patients with this rare neurodevelopmental disorder.
Angelman syndrome, which affects approximately one in 12,000 to 20,000 people globally, leads to developmental delays, cognitive impairments, and severe communication challenges. ION582 is an investigational medicine that aims to increase the production of the UBE3A protein in the brain, which is lacking in Angelman syndrome patients due to a loss of function in the maternal UBE3A gene.
The HALOS study included 51 patients aged 2-50 and assessed the safety and efficacy of ION582 over a three-month period, followed by a long-term extension phase. The study's primary objective was safety, and the drug was well tolerated at all dose levels.
The most robust improvements were observed in cognition, communication, and motor function. Approximately 65% of patients at six months showed improvements in cognition, and about 70% demonstrated better receptive and/or expressive communication. Motor skills also improved in roughly 65% of patients.
The company plans to present detailed results from the HALOS study at the Angelman Syndrome Foundation meeting in July and will discuss the design of the pivotal program with regulatory authorities. ION582 has already received Orphan Drug designation in the U.S.
Ionis, a leader in RNA-targeted therapies, has a growing pipeline of potential treatments for neurological diseases. The company has three approved neurological disease medicines and multiple ongoing Phase 3 studies.

InvestingPro Insights
As Ionis Pharmaceuticals, Inc. (NASDAQ:IONS) continues to make strides in its developmental pipeline, the financial metrics and analyst perspectives offer a window into the company's business health and market expectations. Ionis, with a market capitalization of $5.72 billion, reflects a sizeable presence in the biotech industry. Despite the positive news on ION582, analysts have raised concerns about the company's profitability, as Ionis is not expected to be profitable this year, which aligns with a negative P/E ratio of -14.61, further adjusted to -15.13 for the last twelve months as of Q1 2024.
One of the key InvestingPro Tips for Ionis is the anticipation of a sales decline in the current year, which may be a point of consideration for investors looking at the company's revenue growth trajectory. The company's revenue growth was 34.84% for the last twelve months as of Q1 2024, yet there was a quarterly decline of -8.45% in the same period. This juxtaposition of annual growth against a quarterly decline could signal varying market conditions or product cycle stages that investors may want to monitor closely.
Additionally, Ionis operates with a moderate level of debt, which is a crucial factor for investors to consider in assessing the company's financial resilience. On the balance sheet, Ionis's liquid assets exceed its short-term obligations, which may provide some reassurance regarding the company's ability to meet its immediate financial commitments.
