Ionis Pharmaceuticals stock maintains Buy rating at TD Cowen on pipeline strength

Investing.com - TD Cowen has reiterated a Buy rating and $59.00 price target on Ionis Pharmaceuticals (NASDAQ:IONS), citing the company’s robust cardiometabolic and neurology pipelines with multiple late-stage catalysts. The stock, currently trading near its 52-week high of $71.87, has shown remarkable momentum with a 151.93% gain over the past six months.

The firm highlighted the strong uptake of Tryngolza in familial chylomicronemia syndrome (FCS), with a planned expansion into severe hypertriglyceridemia (sHTG) targeting approximately one million patients. TD Cowen also noted that ION775 demonstrated durable triglyceride-lowering effects after six months.

In the neurology space, ION582 is currently enrolling patients in the Phase 3 REVEAL trial, while zilganersen has shown impressive data, according to the research note. The company is also developing several early-stage next-generation agents.

Management has provided guidance indicating the company expects to reach breakeven by 2028 with peak revenues exceeding $5 billion. The firm characterized Ionis as "firing on all cylinders" with late-stage catalysts ahead.

TD Cowen’s assessment came following Ionis Pharmaceuticals’ Innovation Day, which showcased the company’s pipeline and growth strategy across its key therapeutic areas.
