Dublin Ireland, August 5, 2021 – 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 June 30, 2021 and provided a corporate update.

“We continued to build on our momentum during the recent quarter with the launch of our own SIVEXTRO NDC, and the announcement of positive results from the third successful pivotal trial for lefamulin which support a potential New Drug Application (NDA) in China. We have also extended our cash runway substantially through the first quarter of 2022 as a result of successfully renegotiating our principal debt repayment and activity from our “at the market” offering program during the second quarter.” said Ted Schroeder, Chief Executive Officer of Nabriva Therapeutics.

Mr. Schroeder added, “We saw our commercial efforts continue to gain traction in the community. Our full complement of sales representatives has now been in the field for two full quarters and we are seeing a steady increase in our in-person interactions with healthcare providers, which are now over 70%. The launch of our SIVEXTRO NDC is off to a strong start, with net sales of $6.9 million in the second quarter of 2021. We remain focused on establishing the benefits of XENLETA with healthcare providers to position us to seize on the opportunity for what may be a more normal community-acquired bacterial pneumonia (CABP) season beginning this fall.”

Mr. Schroeder continues, “We are extremely excited about the potential opportunity for lefamulin and for CABP patients in the greater China Region. The positive pivotal trial results for lefamulin in China further validate the effectiveness of lefamulin in treating CABP. We expect that our new partner in China, Sumitomo Pharmaceuticals (Suzhou), the Chinese affiliate of Sumitomo Dainippon Pharma, will file an NDA for lefamulin in China in the second half of 2021. We are looking forward to working with Sumitomo Pharmaceuticals (Suzhou), a well-established commercial partner, on the launch of lefamulin in China. This represents a meaningful financial opportunity, as our collaboration with Sumitomo Pharmaceuticals (Suzhou) provides for low double-digit royalties, and up to $86.0 million in remaining regulatory and commercial milestones.”

Selling, general and administrative expense increased by $2.1 million from $10.7 million for the three months ended June 30, 2020 to $12.9 million for the three months ended June 30, 2021. The increase was primarily due to a $4.4 million increase in advisory and external consultancy expenses primarily related to commercialization activities and professional service fees for the relaunch of XENLETA and SIVEXTRO, partly offset by a $1.1 million decrease in staff costs due to the reduction of headcount, a $0.3 million decrease in stock-based compensation expense, a $0.7 million decrease in legal fees and a $0.2 million decrease in infrastructure costs.

●

Cost of product sales increased by $3.3 million from $0.4 million for the six months ended June 30, 2020 to $3.7 million for the six months ended June 30, 2021. The increase was primarily due to the launch of our own SIVEXTRO NDC on April 12, 2021.

Research and development expenses decreased by $1.8 million from $8.8 million for the six months ended June 30, 2020 to $7.0 million for the six months ended June 30, 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.

About XENLETA

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 www.XENLETA.com.

About SIVEXTRO

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.
