Nabriva Therapeutics Reports First Quarter 2019 Financial Results and Recent Corporate Highlights

Nabriva Therapeutics plc (NASDAQ: NBRV), a biopharmaceutical company engaged in the development of innovative anti-infective agents to treat serious infections, today announced its financial results for the three months ended March 31, 2019 and recent corporate highlights.

“This will be a transformational year for Nabriva as we look forward to the upcoming PDUFA dates for both the intravenous and oral formulations of lefamulin for the treatment of community-acquired bacterial pneumonia (CABP),” said Ted Schroeder, Chief Executive Officer of Nabriva Therapeutics. “Additionally, we will be working with the FDA in the coming weeks to gain a full understanding of the FDA’s comments related to the CONTEPO Complete Response Letter (CRL), with the goal of bringing this important treatment to patients as quickly as possible.”



  • In May 2019, submitted a marketing authorization application for both the intravenous and oral formulations of lefamulin for the treatment of community-acquired pneumonia in adults 18 years of age and older to the European Medicines Agency (EMA).
  • In April 2019, received a Complete Response Letter from the U.S. Food and Drug Administration (FDA) for the New Drug Application (NDA) seeking marketing approval of CONTEPO™ (fosfomycin) for injection for the treatment of complicated urinary tract infections (cUTI), including acute pyelonephritis, due to issues related to facility inspections and manufacturing deficiencies at one contract manufacturer. The FDA did not request any new clinical data and did not raise any concerns with regard to the safety of CONTEPO.
  • In February 2019, announced the FDA accepted the NDAs and granted Priority Review for both formulations of lefamulin with a Prescription Drug User Fee Act (PDUFA) action date for completion of the FDA’s review of August 19, 2019.
  • At the 29th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) that took place in Amsterdam, the Netherlands from April 13-16, 2019, Nabriva Therapeutics presented new data that continue to support lefamulin and CONTEPO as potential first-in-class antibiotics in the United States that target the most common causative pathogens of CABP and cUTI, including multi-drug resistant (MDR) strains.


  • In January 2019, hosted an Investor/Analyst Event featuring discussions with leading clinicians and researchers who addressed current and potential new treatments for CABP and cUTIs. Nabriva management also discussed the commercial strategy for the Company’s investigational antibiotics, lefamulin and CONTEPO. 
  • Partnering
    • In March 2019, announced entry into a license and commercialization agreement with Sunovion Pharmaceutics Canada, Inc. (Sunovion), pursuant to which Sunovion will be responsible for developing, obtaining regulatory approval of and commercializing lefamulin in Canada, and Nabriva Therapeutics received an upfront payment, potential milestone payments upon the achievement of certain regulatory and sales milestone events and royalties on net sales of lefamulin, if any, in Canada.


  • For the three months ended March 31, 2019, Nabriva Therapeutics reported a net loss of $20.2 million, or $0.29 per share, compared to a net loss of $13.3 million, or $0.36 per share, for the three months ended March 31, 2018. Revenues decreased by $5.8 million from $7.6 million for the three months ended March 31, 2018 to $1.7 million for the three months ended March 31, 2019, primarily due to a decrease in collaboration revenue of $5.5 million.
  • Research and development expenses decreased by $2.7 million from $10.3 million for the three months ended March 31, 2018 to $7.5 million for the three month ended March 31, 2019. The decrease was primarily due to a $2.6 million refund of payment of the NDA fees to the FDA for CONTEPO, and a $1.5 million decrease in research materials and purchased services related to the development of lefamulin, partly offset by a $0.7 million increase in research consulting fees and a $0.6 million increase in staff costs due to the addition of employees.
  • General and administrative expense increased by $3.3 million from $10.1 million for the three months ended March 31, 2018 to $13.4 million for the three month ended March 31, 2019. The increase was primarily due to a $1.8 million increase in staff costs due to the addition of employees, a $0.8 million increase in stock‑based compensation expense and a $0.6 million increase in external consultancy expenses.
  • As of March 31, 2019, Nabriva Therapeutics had $91.3 million in cash, cash equivalents and short-term investments compared to $102.2 million as of December 31, 2018. Existing cash resources are expected to fund operations into the second quarter of 2020.
