Everest Medicines Announces Positive Results of In Vitro Study of Xerava (eravacycline) Against Human Mycoplasmas

June 22, 2020

Xerava demonstrated greater potency against a select group of mycoplasma species in comparison to four other antimicrobials

Data suggest Xerava may provide alternative treatment option for some respiratory infections caused by drug susceptible and resistant mycoplasmas

SHANGHAI, China – June 22, 2020 (GLOBE NEWSWIRE) -- Everest Medicines, a biopharmaceutical company focused on developing and commercializing transformative pharmaceutical products that address critical unmet medical needs for patients in Greater China and other parts of Asia, today announced results from an  in vitro study in which eravacycline (marketed as Xerava in the US and EU) demonstrated markedly greater potency against drug susceptible and resistant mycoplasmas than tetracycline, azithromycin, moxifloxacin, and clindamycin. These results suggest Xerava merits further clinical study as a potential therapeutic option to macrolides and existing antibiotics for the treatment of some respiratory infections caused by human mycoplasmas.

Findings from the study are published in the June 2020 journal issue of  Antimicrobial Agents and Chemotherapy (AAC). The paper, entitled “ In Vitro Activities of Eravacycline and Other Antimicrobial Agents Against Human Mycoplasmas and Ureaplasmas” is available online  here.

Xerava, along with four other antimicrobials – tetracycline, azithromycin, moxifloxacin, and clindamycin – were evaluated for  in vitro potency against a select group of  Mycoplasma as well as  Ureaplasma species, which are known as atypical pathogens. Susceptibility testing showed that, in addition to greater potency, Xerava demonstrated minimal inhibitory concentrations (MICs) of less than 0.25 μg/ml in almost all 134 isolates tested, including 37 macrolide-, tetracycline-, and/or fluoroquinolone-resistant organisms.

“These types of atypical pathogens are known to play an important role in the cause of respiratory diseases such as bronchitis, and are one of the leading causes of community-acquired pneumonia in China and other Asian countries,” said Sunny Zhu, Chief Medical Officer for Infectious Diseases at Everest Medicines. “In addition to the therapeutic limitations and risks associated with currently available antibiotics, significant increases in the prevalence of drug resistant and MDR Gram-negative bacteria highlight the serious need for new and innovative medicines across infectious respiratory diseases. We look forward to advancing clinical development of Xerava as we work to bring this important therapeutic option to patients in China and Greater Asia.”

About Xerava (eravacycline)

Xerava is a novel, fully synthetic, broad-spectrum parenteral antibiotic of the tetracycline class that has shown broad in vitro activity against Gram-negative pathogens that have acquired multidrug resistance (MDR) and are prevalent in China. Xerava is currently approved for the treatment of complicated intra-abdominal infections (cIAI) in the US and EU. The Company received approval in Singapore for eravacycline in cIAI in April 2020. The Company is conducting a Phase 3 clinical trial in China for cIAI to support regulatory approval to launch in China. Xerava was licensed from Tetraphase Pharmaceuticals.
