Pixium Vision SA reported that its merger with Second Sight Medical Products Inc. has foundered. The combination would have eased Paris-based Pixium’s entry into the U.S. market and Sylmar, Calif.-based Second Sight’s access to the European market, which Pixium has previously opposed, and enabled them to jointly develop and market neuromodulation devices that restore some degree of vision to the blind. The deal had been expected to close early in the second quarter of 2021.
