Leerink analyst Paul Matteis views the 18% pullback in shares of Neurocrine Biosciences (NBIX) over the past few weeks as a buying opportunity. The analyst finds the catalyst for the selloff "difficult to pinpoint," but notes he's been receiving questions from investors on the size of the market opportunity for vesicular monoamine transporters in Tardive Dyskinesia. A doctor survey suggests a target market of 300,000 TD patients for Neurocrine's and Teva's VMAT2 inhibitors, which is enough to offer a "significant revenue opportunity" for both drugs, Matteis tells investors in a research note. Further, the analyst believes the upcoming Phase II data in Tourette's Syndrome, which he sees as having a high probability of success, offers a "nice catalyst for investors" into Q1 of next year. Matteis reiterates an Outperform rating on Neurocrine with a $70 price target.

Vanda Pharmaceuticals "announced that the Supreme Court denied Vanda's petition for a writ of certiorari in its HETLIOZ(R) Abbreviated New Drug Application litigation against Teva Pharmaceuticals USA, Inc., Apotex Inc. and Apotex Corp." CEO Mihael H. Polymeropoulos stated: "We are disappointed that the Supreme Court has decided not to hear our case and clarify the lower court standard for obviousness in patent law. However, we are pleased that our case has drawn attention to an area of law that has broad and significant implications in life sciences innovation."
