AXSM Eyes Expansion With Potential Nod to AXS-12

A potential nod to AXS-12 should boost Axsome’s narcolepsy franchise.

Axsome completed its acquisition of a commercialized drug targeting narcolepsy, Sunosi (solriamfetol), from Jazz Pharmaceuticals (JAZZ - Free Report) in 2022.

Sunosi’s net product sales were $33.9 million in the first quarter of 2026, up 34% from the year-ago quarter’s level.

The acquisition of Sunosi from Jazz diversified Axsome’s commercial portfolio. The drug has become an important revenue driver for Axsome.

However, competition in the target market is growing, which remains a concern.

Alkermes (ALKS - Free Report) is developing alixorexton, a novel, investigational, oral, selective orexin 2 receptor agonist, in late-stage studies for the treatment of narcolepsy type 1 and narcolepsy type 2.

ALKS is also developing alixorexton in mid-stage studies for treating idiopathic hypersomnia. The successful development and potential approval of alixorexton is likely to induce acute competition for Axsome’s Sunosi as well as AXS-12.

Jazz’s other sleep disorder drugs, Xyrem and Xywav, also have a strong foothold in the target market.

AXSM's Zacks Rank & Stock to Consider
