DUBLIN, Ireland and Fort Washington, Pa., January 10, 2022 -- Nabriva Therapeutics plc (NASDAQ: NBRV), a biopharmaceutical company engaged in the commercialization and development of innovative anti-infective agents to treat serious infections, announced a business update today and preliminary, unaudited financial results for the fourth quarter of 2021.

“We made excellent progress in 2021 in spite of the COVID pandemic and are poised for continued growth in 2022,” commented Ted Schroeder, Chief Executive Officer of Nabriva Therapeutics. “We had a strong close to 2021 for SIVEXTRO, which contributed to extending our cash runway well into the fourth quarter of 2022 and we continue to propel the product back to historical prescription trends through our promotional efforts.” Mr. Schroeder continued, “while our commercialization efforts for XENLETA have faced significant headwinds due to the global pandemic, we remain focused on maximizing the value of this novel, first-in-class antibacterial agent in the U.S. through our focused commercial investments, and outside the U.S. by expanding our partnerships globally.”

“We have also made significant progress in executing on life-cycle management opportunities for XENLETA with the initiation of a Phase I trial for CF and early-stage work focused on drug-resistant sexually transmitted infections and other unmet medical conditions for this important drug.” Mr. Schroeder added, “we stand ready to resubmit our New Drug Application for CONTEPO and potentially bring this important antibiotic to the U.S. market once COVID-related travel restrictions are lifted and the U.S. Food and Drug Administration (FDA) is able to complete inspections of our manufacturing partners in the European Union.”

In 2021, we positioned the growth of our business by:

· Launching Nabriva’s own National Drug Code (NDC) of SIVEXTRO in April 2021

· Reporting positive Phase III trial results for lefamulin in China in May 2021

· Transitioning lefamulin commercial rights in China to Sumitomo Pharmaceuticals in May 2021

· Receiving approval of lefamulin in Taiwan in September 2021

· Contracting with Vizient Health in September 2021 to enhance access for XENLETA

· Publishing data on anti-inflammatory effects of lefamulin in PLOS ONE in November 2021

· Achieving acceptance of our New Drug Application by the National Medical Products Administration (NMPA) in China in November 2021

· Launching a 10-count blister pack or “X Pack” of XENLETA in November 2021 to improve distribution and customer access

In 2022, we look for continued growth through execution on key milestones including:

· Growing SIVEXTRO sales to historical levels by mid-2022

· Pulling through hospital transition of care opportunity for XENLETA with Vizient Health

· Enrolling the first patient in our Phase I CF trial in the first quarter

· Geographic expansion of commercialization and distribution partnerships for lefamulin in the EU and the rest of the world

· Continuing to work with FDA to bring CONTEPO to market in the U.S.

· Assessing other business development opportunities to add to our product portfolio and leverage current infrastructure

Preliminary Financial Results

The company enters 2022 with $47.7 million of cash, cash equivalents and short-term investments as of December 31, 2021 compared to $52.2 million of cash, cash equivalents and short-term investments as of September 30, 2021. As a result of the strong close to 2021 for SIVEXTRO sales, and improved operating efficiencies within the business, our cash balance as of December 31, 2021 is expected to fund our operations, debt service obligations and capital expenditure requirements well into the fourth quarter of 2022. In addition, we anticipate reporting that total revenue for the fourth quarter of 2021 grew at a mid-to-high single digit percentage versus third quarter of 2021’s reported total revenue of $8.9 million.

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.

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.
