SAN DIEGO, March 30, 2016 /PRNewswire/ — Zavante Therapeutics, Inc., a privately held, late clinical-stage biopharmaceutical company, today announced that it has closed a $45 million Series A financing, consisting of $35 million from new investors and $10 million from the conversion of outstanding convertible notes. Proceeds from the financing will be used for the development of the Company’s lead product candidate, ZTI-01 (fosfomycin for injection), an injectable antibiotic with a differentiated mechanism of action designed for use in the hospital setting. In the second quarter of 2016, Zavante plans to initiate the ZEUS Study, a single pivotal clinical trial for ZTI-01, a first-in-class broad spectrum IV antibiotic under development to treat multidrug resistant (MDR) pathogens.

Participating in the round were co-leaders Frazier Healthcare Partners and Longitude Capital, as well as Aisling Capital. In conjunction with this financing, Patrick Heron, managing general partner of Frazier Healthcare Partners’ Life Sciences team, and David Hirsch, M.D., Ph.D., managing director and founder of Longitude Capital, will join the Zavante board of directors. Andrew Schiff, M.D., managing partner of Aisling Capital, will take an observer seat.

“Closing a $45 million Series A financing is a significant achievement that we believe demonstrates tremendous support for our differentiated, injectable antibiotic as we prepare to conduct the pivotal ZEUS Study,” said Ted Schroeder, founder, president and CEO of Zavante. “We have a strong team in place and now we have the financial backing to accelerate the development of our lead product candidate, ZTI-01, with a goal of providing improved anti-infective therapeutic options in the hospital setting.”

ZTI-01 is a first-in-class injectable epoxide antibiotic that has demonstrated a broad spectrum of bactericidal gram-negative and gram-positive activity, including activity against most contemporary MDR bacterial strains, for which current antibiotic therapeutic choices are severely limited. In September 2014, the FDA initially granted Qualified Infectious Disease Product (QIDP) designation for ZTI-01 for the indication of complicated urinary tract infections (cUTI). In December 2015, the FDA expanded the QIDP designations for ZTI-01 to include complicated intra-abdominal infections (cIAI), hospital-acquired bacterial pneumonia (HABP)/ventilator-associated bacterial pneumonia (VABP), and acute bacterial skin and skin structure infections (ABSSSI). Additionally, the FDA granted fast-track designations for all four QIDP designations. These QIDP designations make ZTI-01 eligible for certain incentives available for the development of new antibiotics, including priority FDA review and an additional five-years of market exclusivity under the Generating Antibiotic Incentives Now (GAIN) Act.

“We are looking forward to collaborating with Zavante’s experienced management team as they develop new therapeutic regimens for use in the hospital setting,” said Heron. “We believe there is ample opportunity to develop late-stage antibiotics that can transform healthcare and address unmet needs.”

“Zavante Therapeutics is in a great position to achieve its goal of developing novel therapies to improve the outcomes of hospitalized patients with its first product candidate ZTI-01, which is entering into its pivotal study soon,” added Dr. Hirsch. “Our organization supports backing companies like Zavante because they have the tools to get the job done.”

Heron and Hirsch join Schroeder and the Company’s Founder and Chairman Cam Garner on Zavante’s Board of Directors.
