MerLion Pharmaceuticals (“MerLion”) today announced that a joint project with the Defence Science and Technology Laboratory, UK (Dstl) titled “‘Efficacy of Finafloxacin against Biological Threat Agents” has been awarded a grant from the United States’ Defense Threat Reduction Agency (DTRA) Chemical and Biological Defense Program.

The multi-year, multi-phase project will study the impact of MerLion’s novel fluoroquinolone finafloxacin for the treatment of infections caused by the biological threat agent Burkholderia pseudomallei (B. pseudomallei). In addition, the broad spectrum efficacy of finafloxacin against other intracellular bio-threat agents such as Francisella tularensis (F. tularensis) and Yersinia pestis (Y. pestis), and other multi-drug resistant (MDR) pathogens of clinical significance will be investigated in further detail.

During the initial period of the project MerLion and Dstl will work towards gaining U.S. Food and Drug Administration (FDA) agreement about the next steps for the development of finafloxacin as an approved antibiotic.

This project will build on data generated both in vitro and in vivo in an existing long-standing collaboration between Dstl and MerLion which has shown that, in addition to activity against MDR pathogens, finafloxacin has significant potential for the treatment of bio-threat agents. Finafloxacin has already demonstrated strong and rapid-onset activity against B. pseudomallei, F. tularensis and other intracellular bio-threat pathogens.

Finafloxacin acts powerfully against two bacterial molecular targets and its rapid bactericidal effect is further enhanced by its activity in the acidic environment found at most sites of bacterial infection.

In addition, finafloxacin has been shown to be a poor substrate of the major multidrug efflux transporters which affect other fluoroquinolones and is thus able to maintain its efficacy against fluoroquinolone-resistant B. pseudomallei where resistance caused by efflux pumps is predominant.

MerLion has previously reported positive results for finafloxacin from a Phase 2 study in patients hospitalized with complicated urinary tract infections (cUTI) and pyelonephritis which showed that a five day course, starting with IV and switching to oral dosing, was more effective that treatment with the current standard of care (ciprofloxacin).

“We already have compelling pre-clinical results generated in the collaboration with our partners from Dstl for finafloxacin’s activity against various bio-threat pathogens, as well as data from our positive clinical studies treating patients with cUTI infections”, said David Dally, CEO of MerLion.

He added that “The new project will enable us to investigate the activity of finafloxacin against a variety of very difficult-to-treat pathogens in more detail and will help to position finafloxacin as an effective therapy against multiple bioterrorism threats, as well as a treatment for other life-threatening infections.”

About Finafloxacin

Finafloxacin is a novel fluoroquinolone antibiotic with many “best in class” features. In clinical and pre-clinical settings the compound has shown a substantially improved therapeutic profile as compared to the existing gold standard and a broad utility in treating many severe infections, including those caused by resistant Gram-negative pathogens.

Finafloxacin’s superior profile arises from the compound’s unique mode of action, being equally active at physiological pH conditions and in the acidic environments which occur at the most sites of bacterial infections. Most other antibiotics, including other fluoroquinolones, show decreased activity under acidic tissue conditions, which result in significantly reducing their overall efficacy.

Results from a double-blind controlled clinical Phase 2 trial revealed a higher, more rapid and sustained level of microbiological eradication and improved clinical outcomes for patients treated with finafloxacin compared to those treated with ciprofloxacin. The trial’s primary and secondary endpoints were all successfully achieved. Finafloxacin was found to be both safe and well tolerated.

MerLion has developed IV and oral formulations of finafloxacin with equivalent bioavailability, offering physicians various options for in-hospital and out-patient treatment regimens.

MerLion has licensed Finafloxacin to a major pharmaceutical partner for use in North America for ear infections. In 2014 Xtoro™, an otic suspension of finafloxacin, was approved by the FDA for treatment of acute otitis externa, commonly known as “swimmer’s ear”, caused by Pseudomonas aeruginosa and Staphylococcus aureus.


About Burkholderia pseudomallei

Burkholderia pseudomallei is a Gram-negative, bipolar, aerobic, motile rod-shaped, soil-dwelling bacterium, endemic in tropical and subtropical regions worldwide. It infects humans and animals and causes the disease melioidosis.
