Vaxcyte Inc. characterized its latest phase II data with VAX-24 as positive but Wall Street wasn’t so sure about the dose-finding outcomes with the 24-valent pneumococcal conjugate vaccine (PCV), and shares of the San Carlos, Calif.-based firm (NASDAQ:PCVX) closed March 31 at $37.76, down $31.70, or 46%.
As U.S. regulatory uncertainty swirls around the vaccine space and health care in general, Vaxcyte Inc. stands poised for a readout of phase II infant data by the end of this quarter with VAX-24, the 24-valent pneumococcal conjugate vaccine (PCV). The San Carlos, Calif.-based firm will offer top-line safety, tolerability, and immunogenicity data, to be followed by top-line data with the booster dose by the end of this year.
SK Bioscience Ltd. and Sanofi Pasteur SA announced June 30 positive results from a phase II study for its 21-valent pneumococcal conjugate vaccine (PCV) candidate called GBP-410, or SP-0202 under Sanofi.
Although strides have been made in the space, biopharma’s hunt for a wider net to cast in vaccines for pneumococcal disease has recruited the likes of Vaxcyte Inc., GSK plc and Merck & Co. Inc., each racing for a candidate with improved valence.
