Vanda Pharmaceuticals stock jumps premarket after FDA clears Bysanti — what to watch at the open
Vanda Pharmaceuticals shares jumped 33% to $7.68 in premarket trading Monday after the FDA approved its new antipsychotic pill, Bysanti, late Friday. The drug, milsaperidone, is bioequivalent to Vanda’s existing Fanapt and will be available commercially in the third quarter of 2026. Traders are watching whether the rally holds at the open and how Bysanti will compete in a crowded market.
