Oct 28 (Reuters) – Biogen beat Wall Street estimates for third-quarter results on Wednesday, as strong demand for its rare disease and Alzheimer’s drugs helped offset ​declining sales of its multiple sclerosis treatments.

The drugmaker ‌is banking on Syfovre and Empaveli, treatments acquired from its recent $5.6 billion buyout of Apellis Pharmaceuticals, along with its rare-disease drugs to drive growth, as pricing pressure weighs on its aging multiple sclerosis portfolio.

Sales ‌of ​eye disease drug Syfovre rose 27% ⁠to $191 million in the ⁠third quarter, while kidney disease treatment Empaveli brought in $52 million, up 92% from a year earlier.

Its rare disease portfolio – which includes genetic disorder drug Skyclarys and spinal ​muscular atrophy drug Spinraza – brought in sales of $676 million in the quarter, up 27% from a year earlier.

CEO ⁠Christopher Viehbacher expects upcoming late-stage trial ⁠results over the next year to bolster ​long-term growth, with analysts highlighting lupus drug litifilimab and kidney-disease ​treatment felzartamab as potential growth drivers.

Global sales of its ‌Alzheimer’s drug Leqembi, developed with Eisai, rose 67% from a year earlier to about $202 million, beating analysts’ average expectation of $130.6 million, according to LSEG data.

Biogen is counting on ⁠recent U.S. approvals for a more convenient under-the-skin formulation of Leqembi to drive patient uptake.

Revenue for the quarter rose 11% to $2.8 ⁠billion, and came ‌in above estimates of $2.63 billion.

Biogen raised the ⁠lower end of its 2026 adjusted profit ​forecast by ‌20 cents, projecting a range of $12.20 to $13 ​per share, ⁠compared with its prior expectation of between $12 and $13. The midpoint of the updated range is above expectations of $12.36.

The company reported an adjusted profit of $2.62 per share for the quarter, compared with expectations of $1.99.
