About Us
Zavante is developing novel medicines for the treatment of diseases that affect patients in the hospital setting.
Our lead product candidate, ZOLYD™ (fosfomycin for injection, previously referred to as ZTI-01), is an investigational, first-in-class injectable antibiotic under development to combat serious, life-threatening infections, including those due to multi-drug resistant (MDR) Gram-negative and Gram-positive bacteria. ZOLYD is being developed as a foundational antibiotic for hospitalized patients with infections caused by suspected or confirmed MDR pathogens. Zavante is initially developing ZOLYD to treat complicated urinary tract infections (cUTIs) and has identified additional indications for possible development.
Therapeutic Focus
Growing antimicrobial resistance creates a significant demand for novel therapies. Bacterial resistance to currently available antimicrobials has reached alarmingly high levels, resulting in a global health crisis. To combat this threat, antibiotic treatment options with differing mechanisms of action are critically needed, particularly agents with activity against MDR Gram-negative bacteria. The lack of options for these life-threatening MDR pathogens has prompted national medical agencies and societies, to urgently call for help in bringing forth new antimicrobials.
New tools needed in the fight against MDR pathogens. The CDC has estimated at least 2 million illnesses per year and 23,000 deaths in the U.S. are due to infections caused by MDR pathogens. The difficulty in treating MDR infections is a substantial burden on the U.S. healthcare system; research by the Infectious Diseases Society of America indicates the overall cost related to antibiotic-resistant pathogens in the U.S. ranges from $21 billion to $34 billion annually, and requires an additional eight million hospital days per patient. Development and FDA approval of innovative new classes of antibiotics targeting MDR pathogens in the hospital is an important objective for government policy makers and health care systems across the United States.

ZOLYDTM
ZOLYD™ is an investigational, first-in-class epoxide antibiotic with a broad spectrum of bactericidal Gram-negative and Gram-positive activity, including activity against most contemporary MDR strains that threaten hospitalized patients. Fosfomycin IV has an extensive history from markets outside the U.S., where it has been utilized for over 40 years in nine indications. ZOLYD utilizes a new dosing approach, developed by Zavante, to optimize the compound’s pharmacokinetics and pharmacodynamics.
The company believes that these attributes, along with the positive clinical experience worldwide, support ZOLYD as a first-line treatment for complicated urinary tract infections (cUTI) suspected to be caused by MDR pathogens. Approximately 25% of cUTIs are caused by MDR bacteria and limited treatment options are available. In addition, non-clinical data have shown that ZOLYD acts synergistically with certain other antibiotics to improve bacterial killing and restore susceptibility to agents otherwise demonstrating resistance.
The ZOLYD development program is initially focused on obtaining regulatory approval for the treatment of cUTI, including acute pyelonephritis, with the pivotal ZEUS™ study (ZTI-01 Efficacy and Safety study). In the ZEUS study, ZOLYD met the primary endpoint of statistical non-inferiority to piperacillin/tazobactam in this patient population. Zavante expects to file a New Drug Application utilizing the FDA’s 505(b)(2) pathway in early 2018.
The FDA has granted ZOLYD Qualified Infectious Disease Product (QIDP) and Fast Track designations for:
- Complicated urinary tract infections (cUTI)
- Complicated intra-abdominal infections (cIAI)
- Hospital-acquired bacterial pneumonia (HABP) /
Ventilator-associated bacterial pneumonia (VABP) - Acute bacterial skin and skin structure infections (ABSSSI)
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 found by the U.S. Food and Drug Administration to be safe or effective for any indication.
The lack of available and effective antibiotics for life-threatening multidrug-resistant pathogens has created an important unmet medical need that is widely acknowledged by national medical agencies and societies. An antibiotic with a unique mechanism of action like ZTI-01 would be an important addition to our antibacterial armamentarium when treating seriously ill patients in the hospital.
