Zavante Therapeutics To Present ZOLYD™ Data From Pivotal ZEUS Study At ID Week 2017

SAN DIEGO, Sept. 20, 2017 /PRNewswire/ -- Zavante Therapeutics, Inc., a biopharmaceutical company focused on developing novel therapies to improve the outcomes of hospitalized patients, and its research collaborators will present eight posters related to investigational antibiotic ZOLYD™ (fosfomycin for injection, also known as ZTI-01), at ID Week 2017 to be held October 4-8, 2017 in San Diego.

"Zavante welcomes the opportunity to present in a peer review forum detailed results from our pivotal ZEUS Phase 2/3 clinical trial," said Evelyn J. Ellis-Grosse, Ph.D., Chief Scientific Officer of Zavante Therapeutics. "In the ZEUS study, ZOLYD met the primary endpoint of statistical non-inferiority to piperacillin/tazobactam in patients with complicated urinary tract infections, and we believe these data support our forthcoming new drug application for U.S. registration."

ZEUS was a multicenter, randomized, double-blind Phase 2/3 trial designed to evaluate the safety and efficacy of ZOLYD for the treatment of hospitalized adults with complicated urinary tract infections (cUTI), including acute pyelonephritis (AP), versus piperacillin/tazobactam. New positive ZEUS results to be presented at ID Week include a post-hoc analysis of the primary outcome (defined as clinical cure plus microbiologic eradication at the test-of-cure visit) based upon molecular strain typing of bacterial pathogens in both treatment arms.

The ID Week poster presentations also feature the ZEUS safety and efficacy data in a subset of patients with infections caused by resistant bacteria. In vitro studies evaluating activity of ZOLYD combined with meropenem or cefepime in different resistance models will also be presented at the meeting.

In addition to the company's poster presentations, Dr. Ellis-Grosse will participate in a symposium titled, "New Antibiotics: What's in the Pipeline?" on Thursday, October 5^th, from 2:00 p.m. to 3:30 p.m. Pacific Time and a meet-the-professor session titled, "Pipeline 2.0," on Friday, October 6^th, from 7:00 a.m. to 8:15 a.m. Pacific Time.

Poster details for the meeting are as follows. The complete program can be accessed at the ID Week 2017 website at www.idweek.org.

About ZOLYD (fosfomycin for injection, also known as ZTI-01) 
ZOLYD is an investigational, first-in-class injectable epoxide antibiotic with a broad spectrum of activity in vitro against Gram-negative and Gram-positive bacteria, including activity against most multi-drug resistant strains that are of particular concern to public health. ZOLYD has a differentiated mechanism of action that acts at an earlier step in cell wall synthesis inhibition, providing activity against pathogens that are often resistant to other classes of antibiotics. Zavante recently reported that ZOLYD met the primary endpoint of statistical non-inferiority to piperacillin/tazobactam in the pivotal ZEUS clinical trial in hospitalized patients with cUTI, including AP.  

The U.S. Food and Drug Administration has granted Fast Track and Qualified Infectious Disease Product designations for the investigation of ZOLYD for cUTI, hospital-acquired bacterial pneumonia (HABP), ventilator-associated bacterial pneumonia (VABP) infections, acute bacterial skin and skin structure infections (ABSSSI), and complicated intra-abdominal infections (cIAI). These designations make ZOLYD 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.

ZOLYD is an investigational medication that has not been approved by the FDA for any indication.

Forward-looking statements contained in this press release include statements about the company's belief that data from the ZEUS study will be sufficient to support a new drug application (NDA) for U.S. registration of ZOLYD. Forward-looking statements are not historical facts or assurances of the company's future performance, but are based on management's current beliefs, expectations and assumptions and are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and may be outside of the company's control.  Because the company's actual results and financial condition may differ materially from those indicated in the forward-looking statements, you should not rely on any such forward-looking statements.
