Roche’s Vabysmo disappointed investors again. In the second quarter, the eye drug’s sales of about 1.04 billion Swiss francs ($1.27 billion) missed analysts’ expectations by 7.1%. | On an investor call Thursday, Roche Pharmaceuticals CEO Teresa Graham assured analysts that the U.S. branded market has stabilized after a period of contraction, though the explosive growth that Vabysmo enjoyed early in its launch is likely behind it.
