DUBLIN, Ireland, March 29, 2022 (GLOBE NEWSWIRE) -- 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 and year ended December 31, 2021 and provided a corporate update.

"We saw continued progress in our commercial business during the fourth quarter of 2021, with total revenue for the quarter growing to $9.3 million, of which $8.2 million was attributed to SIVEXTRO sales. In line with our expectations, prescription growth for SIVEXTRO continued in the fourth quarter growing 5% year over year, as well as registering our third consecutive quarter of sequential quarterly prescription growth," said Ted Schroeder, Chief Executive Officer of Nabriva Therapeutics. "Our strong close to 2021 for SIVEXTRO was also supported by improved operating efficiencies within our business, which contributed to extending our cash runway well into the fourth quarter of 2022."

Mr. Schroeder added, "We are proud of the progress made in 2021 and encouraged as we look forward to what we can execute on in 2022. We remain focused on driving growth of SIVEXTRO, educating the medical community on the benefits of XENLETA, and expanding XENLETA geographically as we continue to assess partnership opportunities."

FINANCIAL RESULTS

Three Months Ended December 31, 2021 and 2020

Revenues for the three months ended December 31, 2021 were $9.3 million compared to $2.5 million for the three months ended December 31, 2020. The $6.8 million increase was primarily due to a $8.4 million increase in product revenue, net, offset by a $0.1 million decrease in research premiums and grant revenue and a $1.5 million decrease in collaboration revenues.
Cost of revenues for the three months ended December 31, 2021 were $5.3 million compared to $0.4 million for the three months ended December 31, 2020. The $4.9 million increase was primarily due to the launch of our own SIVEXTRO National Drug Code, or NDC, on April 12, 2021.
Research and development expenses for the three months ended December 31, 2021 were $2.4 million compared to $2.8 million for the three months ended December 31, 2020. The $0.5 million decrease was primarily due to a $0.5 million decrease in research materials and purchased services, a $0.3 million decrease in consulting fees, and a $0.1 million decrease in stock-based compensation expense, partly offset by a $0.2 million increase in staff costs and a $0.2 million increase in infrastructure and other costs.
Selling, general and administrative expenses for the three months ended December 31, 2021 were $14.5 million compared to $17.5 million for the three months ended December 31, 2020. The $3.0 million decrease was primarily due to a $1.9 million decrease in commercial consultancy expenses, a $0.6 million decrease in professional fees, a $0.2 million decrease in infrastructure expenses, a $0.1 million decrease in staff costs, and a $0.1 million decrease in stock-based compensation expense.
Net loss decreased $4.8 million from a $17.8 million net loss for the three months ended December 31, 2020 to $13.1 million net loss for the three months ended December 31, 2021.

Years Ended December 31, 2021 and 2020

Revenues for the year ended December 31, 2021 were $28.9 million compared to $5.0 million for the year ended December 31, 2020. The $23.9 million increase was primarily due to $23.8 million in SIVEXTRO product revenue, net since the launch of SIVEXTRO under our own NDC on April 12, 2021.
Cost of revenues for the year ended December 31, 2021 were $13.1 million compared to $0.8 million for the year ended December 31, 2020. The $12.4 million increase was primarily due to the launch of SIVEXTRO under our own NDC on April 12, 2021. Cost of revenues for XENLETA primarily represents direct and indirect manufacturing costs, while cost of revenues for SIVEXTRO represent the actual purchase cost for the finished product from Merck. Prior to the U.S. Food and Drug Administration approval of XENLETA on August 19, 2019, the inventory costs for XENLETA were expensed as research and development expenses since the approval was outside of our control and therefore not considered probable. As such, the majority of the expenses incurred for our initial inventories of XENLETA has been previously expensed. For the years ended December 31, 2021 and 2020, cost of revenues includes a $0.3 million and a $0.7 million, respectively, non-cash reserve adjustment for excess and obsolete inventory due to timing of expiring inventory.
Research and development expenses for the year ended December 31, 2021 were $12.6 million compared to $15.1 million for the year ended December 31, 2020. The $2.5 million decrease was primarily due to a $0.7 million decrease in stock-based compensation expense, a $1.0 million decrease in staff costs, and a $0.7 million decrease in study costs.
Selling, general and administrative expenses for the year ended December 31, 2021 were $51.6 million compared to $55.3 million for the year ended December 31, 2020. The $3.6 million decrease was primarily due to a $5.9 million decrease in staff costs due to the reduction of headcount, a $1.2 million decrease in stock-based compensation expense, a $0.7 million decrease in travel costs, a $0.6 million decrease in infrastructure costs, and a $2.5 million decrease in professional fees, partly offset by a $7.4 million increase in advisory and external consultancy expenses primarily related to commercialization activities and professional service fees for the relaunch of SIVEXTRO and XENLETA.
Net loss decreased $20.0 million from a $69.5 million net loss for the year ended December 31, 2020 to a $49.5 million net loss for the year ended December 31, 2021.
As of December 31, 2021, the Company had cash and cash equivalents of $47.7 million. Based on its current operating plans, the Company expects that its existing cash resources will be sufficient to enable it to fund its operating expenses, debt service obligations and capital expenditure requirements well into the fourth quarter of 2022.

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.
