Nabriva Therapeutics Reports First Quarter 2017 Financial Results

- Expects top-line data from LEAP 1 CABP Phase 3 trial in third quarter 2017 and from LEAP 2 CABP Phase 3 trial in first quarter 2018

Vienna, Austria / King of Prussia, PA, May 12, 2017 — Nabriva Therapeutics AG (NASDAQ: NBRV), a clinical stage biopharmaceutical company engaged in the research and development of novel anti-infective agents to treat serious infections, with a focus on the pleuromutilin class of antibiotics, today provided a business and clinical development update and reported its financial results for the three months ended March 31, 2017.

“Nabriva remains on-track for a potentially transformational year with last patient, last visit for the LEAP 1 trial scheduled to occur by the end of May and top-line clinical data for the LEAP 1 trial expected in the third quarter of 2017,” said Dr. Colin Broom, Chief Executive Officer of Nabriva. “Additionally, based on current projections, we continue to expect to complete patient enrollment for LEAP 2 in the fourth quarter of 2017 and anticipate receiving top-line data for LEAP 2 in the first quarter of 2018.”

RECENT CORPORATE AND DEVELOPMENT HIGHLIGHTS

·            Following completion of lefamulin evaluation against pneumonia (LEAP) 1 patient enrollment in April 2017 and estimation of final data collection and analysis timelines, the company expects to announce LEAP 1 top-line efficacy and safety data in the third quarter of 2017. LEAP 1 is a Phase 3 global, registrational clinical trial evaluating the safety and efficacy of lefamulin (IV/oral) in patients with moderate to severe community-acquired bacterial pneumonia (CABP).

·            At the 27th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) that took place in Vienna, Austria from April 22-25, 2017, Nabriva showcased nine abstracts, three of which were selected as oral presentations. These data are part of a growing body of evidence supporting lefamulin’s profile as a potential first-line, empiric treatment for the key pathogens, including multidrug resistant strains, that are known to cause CABP.

·            On April 17, 2017, Nabriva announced that its supervisory board and management board approved the redomiciliation of the holding company of Nabriva Therapeutics AG (Nabriva AG) and its subsidiaries (Nabriva Group) from Austria to Ireland. The redomicilation will be effected by the exchange of American depositary shares and common shares of Nabriva AG for shares of Nabriva Therapeutics Plc (Nabriva Ireland), a newly-formed Irish public limited company, with Nabriva Ireland becoming the publicly-traded parent entity of Nabriva AG. Once the transaction is completed, the current Austrian publicly-traded parent company, will become a subsidiary of the newly-formed Irish company, and it is expected that Nabriva Ireland will then become the publicly-traded parent company of the Nabriva Group with its tax residency in Ireland.

FIRST QUARTER 2017 FINANCIAL HIGHLIGHTS

·            For the three months ended March 31, 2017, Nabriva reported a net loss of $15.2 million or $5.60 per share, compared to a net loss of $13.6 million or $6.42 per share for the three months ended March 31, 2016.

·            Research and development expenses decreased by $0.4 million from $13.0 million for the three months ended March 31, 2016 to $12.6 million for the three months ended March 31, 2017. The change was primarily due to higher costs related to the initiation and continuation of patient enrollment for LEAP 1 and LEAP 2 during the three months ended March 31, 2016. Research materials and purchased services for the company’s other programs and initiatives were relatively limited during both periods.

·            General and administrative expense increased by $1.1 million from $3.1 million for the three months ended March 31, 2016 to $4.2 million for the three months ended March 31, 2017. The increase was primarily due to a $0.7 million increase in legal fees related to the redomiciliation of the company’s ultimate parent company from Austria to Ireland and a $0.4 million increase in pre-commercialization activities and increased professional service fees.

·            As of March 31, 2017, Nabriva had $68.2 million in cash, cash equivalents and short-term investments compared to $83.9 million as of December 31, 2016.

·            As of April 30, 2017, Nabriva had 2,721,086 common shares outstanding, of which 2,260,443 were represented by 22,604,430 ADSs. Each Nabriva common share is equivalent to 10 ADSs.

About Nabriva Therapeutics AG

Nabriva Therapeutics is a clinical stage biopharmaceutical company engaged in the research and development of novel anti-infectives to treat serious infections, with a focus on the pleuromutilin class of antibiotics. Nabriva Therapeutics’ medicinal chemistry expertise has enabled targeted discovery of novel pleuromutilins, including both intravenous and oral formulations of its lead product candidate, lefamulin. Lefamulin is a novel semi-synthetic pleuromutilin antibiotic with the potential to be the first-in-class available for systemic administration in humans.  The company believes that lefamulin is the first antibiotic with a novel mechanism of action to have reached late-stage clinical development in more than a decade.  Lefamulin is currently being evaluated in two global, registrational Phase 3 clinical trials in patients with moderate to severe CABP.  Nabriva believes lefamulin is well positioned for use as a first-line empiric monotherapy for the treatment of moderate to severe CABP due to its novel mechanism of action, targeted spectrum of activity, resistance profile, achievement of substantial drug concentration in lung tissue and fluid, oral and IV formulations and a favorable tolerability profile. Nabriva Therapeutics intends to further pursue the development of lefamulin for additional indications, including the treatment of acute bacterial skin and skin structure infections (ABSSSI), and are developing a formulation of lefamulin appropriate for pediatric use.

Nabriva Therapeutics owns exclusive, worldwide rights to lefamulin, which is protected by composition of matter patents issued in the United States, Europe and Japan.
