PaxVax Announces New Commercial Senior Leadership Appointments<br /><br />MENLO PARK and SAN DIEGO – MARCH 3, 2014 – PaxVax Inc., a specialty vaccine company focused on travelers and biodefense markets with a social mission to ensure global access to its vaccines, today announced the expansion of its commercial leadership team, including appointments of: Linda Rubinstein as Chief Financial Officer; Piers Whitehead as Chief Corporate Development Officer; and Thomas Yonker as Vice President of Project Management.<br /><br />PaxVax has created a clinical-stage product portfolio, including its lead product, PXVX0200, an oral, single-dose cholera vaccine currently completing Phase 3 clinical trials. In recognition of the lack of an available U.S. traveler’s vaccine against cholera, PXVX0200 has been granted Fast Track designation by the U.S. Food and Drug Administration. PaxVax’s biodefense specialty pipeline also includes a pandemic H5N1 influenza vaccine, which recently concluded a successful Phase 1 clinical trial, as well as a vaccine for anthrax, which is currently in a Phase 1 clinical trial in collaboration with the U.S. National Institutes of Health (NIH).<br /><br />“I am very pleased to welcome Linda, Piers, and Tom to the PaxVax team. All are accomplished business executives who bring to the company decades of biologics, vaccines, and business expertise,” said Kenneth Kelley, Chief Executive Officer of PaxVax. “Currently, no single-dose cholera vaccine is available in the world today. In anticipation of U.S. regulatory approval of PXVX0200, we believe the cumulative experience of Linda, Piers, and Tom will help PaxVax successfully transition our candidate vaccines from R&D to commercialization.”<br /><br />Ms. Rubinstein has more than 25 years of operational, financial, and capital markets experience in life science, software, and investment banking. Previously, she served as Senior Vice President and Chief Financial Officer (CFO) of Ingenuity Systems, which was acquired by QIAGEN in 2013, and Vice President and CFO of Solexa, which was acquired by Illumina in 2007.
