Antabio Announces First Subjects Dosed in Phase 1 Clinical Trial of MEM-ANT3310, a Highly Differentiated Antibiotic for Severe Hospital Infections

 

MEM-ANT3310 has the potential to become the next standard of care for life-threatening infections due to its unique coverage including carbapenem-resistant Enterobacterales and Acinetobacter baumannii

 

Labège, France - May 25, 2023

 

Antabio SAS, a clinical stage biopharmaceutical company developing novel treatments for severe drug-resistant bacterial infections, announces dosing of the first subjects in its Phase 1 clinical trial of MEM-ANT3310.

 

MEM-ANT3310 is a next generation antibacterial combination that has been designed to make a significant impact on the growing problem of antimicrobial resistance in serious hospital infections.

 

MEM-ANT3310 combines the well-known carbapenem meropenem (MEM) with ANT3310, a breakthrough serine-beta-lactamase (SBL) inhibitor developed by Antabio. This combination has been designed to provide a unique coverage of priority Gram-negative pathogens including OXA-carbapenem-resistant Acinetobacter baumannii (CRAB), KPC- and OXA- carbapenem-resistant Enterobacterales (CRE), and Pseudomonas aeruginosa (PA).

 

ANT3310 represents an important advance as its innovative structure completely inhibits the enzymes that confer resistance and as a result, restores MEM’s activity against these deadly pathogens.

 

Magdalena Zalacain, Chief Scientific Officer of Antabio said, “MEM-ANT3310 is the culmination of a very creative and focused program aiming to develop a truly differentiated antibiotic active against both CRAB and CRE pathogens. MEM-ANT3310 is a strong addition to the clinical armamentarium to treat severe or life-threatening infections due to Gram-negative pathogens.

 

The Phase 1 clinical trial is designed to assess the safety, tolerability, and pharmacokinetic (PK) profile of single and multiple ascending doses (SAD/MAD) of intravenous ANT3310 administered alone, followed by an assessment of the combination of ANT3310 with MEM in healthy volunteers.

 

Carole Sable, M.D., Infectious Disease expert and clinical advisor of Antabio commented, “There is a very clear need for safe and effective therapies to treat serious antibiotic-resistant infections in hospitalized patients, including when polymicrobial infections are suspected. Based on the preclinical profile of MEM-ANT3310, I believe it has the potential to provide a valuable broad-spectrum therapeutic option to meet unmet medical needs of this high-risk patient population.”

 

Marc Lemonnier, CEO of Antabio added, “We are thrilled to reach this important milestone with the start of our first in man study for MEM-ANT3310. We see great promise for patients in this novel antibacterial combination addressing the highest WHO priorities for antibiotic resistance while building on a well-established regulatory path towards approval.”

 

Initial funding for the development of MEM-ANT3310 of €5.5 million was received in 2022 from the French government through the “ARPEGE” program.
