Nabriva Therapeutics plc (NASDAQ: NBRV), a biopharmaceutical company engaged in the commercialization and development of innovative anti-infective agents to treat serious infections, today announced its financial results for the three months ended March 31, 2021 and provided a corporate update.

“Our commercial efforts continue to accelerate, strengthening awareness and laying the groundwork for prescription growth for both SIVEXTRO and XENLETA in the community. In spite of a dramatic reduction in influenza-like illnesses to historical lows as a result of the impact of COVID-19 hygienic protocols, we are especially encouraged by the trends we have recently seen in our ability to increase call frequency, especially the significant increase in face-to-face interactions with health care providers which has increased 14% in the last 2 months to 64%,” said Ted Schroeder, Chief Executive Officer of Nabriva Therapeutics.

Mr. Schroeder continues “Given the data we have on the performance of SIVEXTRO while it was actively promoted in the past, our initial efforts are hyper-focused on re-establishing SIVEXTRO prescribers to accelerate the return of SIVEXTRO to peak levels of prescription demand. We anticipate several macro forces may augment our efforts including the continued expansion of COVID-19 vaccination and easing of restrictions across the U.S., while also entering the warm weather months when the incidence of acute bacterial skin and skin structure infections (ABSSSI) typically peaks.”

Mr. Schroeder added, “These encouraging trends in face-to-face interactions should also benefit XENLETA prescriber adoption. We continue to advance our sales efforts to prepare the market for the fall and winter, when community-acquired bacterial pneumonia (CABP) is most prevalent. We believe an unmet medical need exists for the treatment of CABP in patients with co-morbidities such as diabetes or COPD. XENLETA is a short-course, 5-day treatment option that provides equivalent effectiveness as a 7-day treatment course with a respiratory fluoroquinolone, is well tolerated and has a novel mechanism of action to combat the growing threat of antimicrobial resistance, and offers prescribers an important addition to their armamentarium in this difficult to treat patient population.”

Mr. Schroeder continues, “We also recently initiated distribution of SIVEXTRO under the Nabriva National Drug Code (NDC), enabling us to recognize 100% of SIVEXTRO net sales and related cost of product sales in our results of operations. In preparation for this demand, the three largest US wholesalers have purchased SIVEXTRO from Nabriva beginning the week of April 12, 2021, and we will recognize these sales in our Q2 2021 financial results.”


  • On April 12, 2021, Nabriva began exclusive distribution of SIVEXTRO under the Nabriva National Drug Code and will recognize 100% of net product sales and related cost of product sales of SIVEXTRO in its results of operations beginning on April 12, 2021. Going forward, the company expects an improvement in profitability as a result of launching its own NDC. Nabriva expects to record gross sales that are approximately a mid to high single digit multiple of the previously recorded collaboration revenue. These gross sales would then be subject to the standard gross-to-net deductions to arrive at a reported net sales number.
  • On April 5, 2021, the Food and Drug Administration (FDA) granted Nabriva an extension for the re-submission of the New Drug Application for CONTEPO with the FDA to June 19, 2022. The extension of the re-submission timeline was granted due to the ongoing COVID-related travel restrictions that have impacted the Agency’s ability to conduct onsite inspections of foreign manufacturing facilities. The extension provides the Agency adequate time to assess the application of the recently issued guidance entitled “Remote Interactive Evaluations for Oversight of Drug Facilities During COVID-19” to the CONTEPO re-submission.
  • On March 10, 2021, Nabriva’s Board of Directors elected Steven Gelone, Pharm D, as a member of its Board of Directors. Dr. Gelone has served as Nabriva’s President and Chief Operating Officer since July 24, 2018.
  • On March 1, 2021, Nabriva announced that it had entered into a definitive agreement with certain healthcare-focused and institutional investors for the purchase and sale of ordinary shares (or pre-funded warrants in lieu thereof) and warrants in a registered direct offering priced at-the-market under Nasdaq rules for aggregate net proceeds of $23.4 million, after deducting the placement agent fees and offering expenses.
  • On February 26, 2021, Nabriva announced the appointment of Daniel Dolan as Chief Financial Officer (CFO), effective as of the close of business on March 12, 2021. Mr. Dolan replaced Gary Sender who retired from Nabriva. Mr. Sender has agreed to serve as a consultant to Nabriva at least through the remainder of 2021 to support Mr. Dolan’s transition into the CFO role.


Three Months Ended March 31, 2020 and 2021

  • Revenues increased by $1.7 million from $0.8 million for the three months ended March 31, 2020 to $2.5 million for the three months ended March 31, 2021, primarily due to an increase of $1.9 million of collaboration revenues for the three months ended March 31, 2021 which includes $0.7 million related to the restructured license agreement with Sinovant, which is being recognized over the estimated period the manufacturing collaboration and regulatory support will be provided to Sinovant, as well as $1.0 million of our share of revenues associated with the SIVEXTRO distribution agreement.
  • Research and development expenses decreased by $1.1 million from $4.9 million for the three months ended March 31, 2020 to $3.9 million for the three months ended March 31, 2021. The decrease was primarily due to a $0.3 million decrease in stock-based compensation expense, a $0.6 million decrease in staff costs, a $0.2 million decrease in research materials and purchased services, and a $0.1 million decrease in travel costs.
  • Selling, general and administrative expense decreased by $4.0 million from $16.0 million for the three months ended March 31, 2020 to $12.0 million for the three months ended March 31, 2021. The decrease was primarily due to a $4.8 million decrease in staff costs due to the reduction of headcount, a $0.6 million decrease in stock-based compensation expense, a $0.7 million decrease in travel costs, a $0.5 million decrease in professional fees partly offset by a $2.5 million increase in advisory and external consultancy expenses primarily related to commercialization activities and professional service fees.
  • Interest expense decreased $0.8 million from $1.0 million for the three months ended March 31, 2020 to $0.2 million for the three months ended March 31, 2021, driven by the repayment of $30.0 million of debt to Hercules during the three months ended March 31, 2020. Nabriva also recorded a one-time non-cash $2.7 million loss during the three months ended March 31, 2020 on the extinguishment resulting from the prepayment.
  • Net operating loss decreased $9.3 million from a $23.3 million loss for the three months ended March 31, 2020, compared to a $14.0 million loss for the three months ended March 31, 2021
  • As of March 31, 2021, Nabriva had $54.8 million in cash and cash equivalents. Based on its current operating plans, Nabriva expects that its existing cash resources, will be sufficient to enable it to fund its operating expenses, debt service obligations and capital expenditure requirements into the fourth quarter of 2021.

About Nabriva Therapeutics plc

Nabriva Therapeutics is a biopharmaceutical company engaged in the commercialization and development of innovative anti-infective agents to treat serious infections. Nabriva Therapeutics received U.S. Food and Drug Administration approval for XENLETA® (lefamulin injection, lefamulin tablets), the first systemic pleuromutilin antibiotic for community-acquired bacterial pneumonia (CABP). Nabriva Therapeutics is also developing CONTEPO™ (fosfomycin) for injection, a potential first-in-class epoxide antibiotic for complicated urinary tract infections (cUTI), including acute pyelonephritis. Nabriva entered into an exclusive agreement with subsidiaries of Merck & Co. Inc., Kenilworth, N.J., USA to market, sell and distribute SIVEXTRO® (tedizolid phosphate) in the United States and certain of its territories.


XENLETA (lefamulin) is a first-in-class semi-synthetic pleuromutilin antibiotic for systemic administration in humans discovered and developed by the Nabriva Therapeutics team. It is designed to inhibit the synthesis of bacterial protein, which is required for bacteria to grow. XENLETA’s binding occurs with high affinity, high specificity and at molecular sites that are different than other antibiotic classes. Efficacy of XENLETA was demonstrated in two multicenter, multinational, double-blind, double-dummy, non-inferiority trials assessing a total of 1,289 patients with CABP. In these trials, XENLETA was compared with moxifloxacin and in one trial, moxifloxacin with and without linezolid. Patients who received XENLETA had similar rates of efficacy as those taking moxifloxacin alone or moxifloxacin plus linezolid. The most common adverse reactions associated with XENLETA included diarrhea, nausea, reactions at the injection site, elevated liver enzymes, and vomiting. For more information, please visit


SIVEXTRO (tedizolid phosphate) was approved by the U.S. Food and Drug Administration in 2014. It is indicated in adults and pediatric patients 12 years of age and older for the treatment of acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible isolates of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) isolates), Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus anginosus group (including Streptococcus anginosus, Streptococcus intermedius and Streptococcus constellatus), and Enterococcus faecalis. To reduce the development of drug-resistant bacteria and maintain the effectiveness of SIVEXTRO and other antibacterial drugs, SIVEXTRO should be used only to treat ABSSSI that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
