A senior analyst at the Japanese banking giant Mizuho raised his price target significantly for Axsome on Monday in a note to investors after news broke that Axsome had settled an important piece of litigation.

No generic competition for now

Axsome announced Monday that it had settled its suit with fellow drugmaker Teva Pharmaceuticals. Axsome was accusing Teva of patent infringement after the latter sought FDA approval to market a generic version of Axsome's key drug, Auvelity. The settlement protects Axsome's exclusive rights over Auvelity for roughly 14 years -- a big win for Axsome.

Mizuho has confidence in Axsome

The resolution led Mizuho's Graig Suvannavejh, PhD, to raise his price target for Axsome from $137 to $195 a share, maintaining his outperform rating. Suvannavejh, who joined Mizuho from Goldman Sachs, explained that the news removes uncertainty around Axsome's bottom line. The clarity makes Axsome more attractive to potential strategic partners -- other drug companies that can help elevate Auvelity sales. He also cited positive momentum from the company's development pipeline. Axsome expects results from two phase 3 trials within the quarter.

Suvannavejh is not alone. Axsome has received positively revised price targets following the settlement from analysts across Wall Street.
