Novavax Reports Fourth Quarter and Year-End 2018 Financial Results

Company to Host Conference Call Today at 4:30 p.m. ET

GAITHERSBURG, Md., March 18, 2019 (GLOBE NEWSWIRE) -- Novavax, Inc. (Nasdaq: NVAX) today announced its financial results and operational highlights for the fourth quarter and twelve months ended December 31, 2018.

"In 2018, we committed to focus on our two lead programs, ResVax™ and Nanoflu™, and reflecting on last year’s activities, I am proud to say we have achieved significant results for both,” said Stanley C. Erck, President and CEO of Novavax, Inc. "Although we were disappointed to miss the primary endpoint of our Prepare trial, ResVax is the first RSV vaccine to demonstrate efficacy for the prevention of RSV disease in a Phase 3 clinical trial. In addition, the successful Phase 2 results for our NanoFlu vaccine provide an opportunity to now confirm with the FDA the use of accelerated approval for licensure. We are now prepared to make meaningful advances on these programs during 2019.”

Fourth Quarter 2018 and Subsequent Operational Highlights

ResVax™ Program

• In February 2019, Novavax announced top-line data from the Prepare trial, which was initiated in December 2015 to determine the efficacy of ResVax against medically significant RSV-positive lower respiratory tract infection (LRTI) in infants. Although the Prepare trial results did not meet the pre-specified primary efficacy endpoint, they demonstrate efficacy against a secondary objective (RSV LRTI hospitalizations). In addition, other pre-specified exploratory endpoints and post-hoc analyses highlight ResVax’ potential to improve global health against serious RSV disease.

NanoFlu™ Program

• In January 2019, Novavax announced positive top-line results of its Phase 2 clinical trial of NanoFlu comparing various quadrivalent formulations, with or without Novavax’ Matrix-M™ adjuvant, with two U.S.-licensed influenza vaccines in older adults. These results show that NanoFlu with Matrix-M generated enhanced immune responses compared to the unadjuvanted formulation, and importantly, showed superior hemagglutination inhibition antibody (HAI) responses against wild-type A(H3N2) viruses, including drifted strains, when compared to Fluzone^® High-Dose, the leading flu vaccine in older adults.

Key Upcoming Events

• Continue ongoing discussions with the FDA, European regulatory agencies, and potentially other national regulatory agencies, to assess opportunities for submission of marketing license applications for ResVax.
• Reach agreement with the FDA during the second quarter of 2019 on a proposed Phase 3 study design for NanoFlu utilizing accelerated approval criteria.
• Present ResVax Phase 3 trial data at the 37^th Annual Meeting of the European Society for Paediatric Infectious Diseases (ESPID) on May 7, 2019.

Financial Results for the Three and Twelve Months Ended December 31, 2018

Novavax reported a net loss of $49.3 million, or $0.13 per share, for the fourth quarter of 2018, compared to a net loss of $50.8 million, or $0.16 per share, for the fourth quarter of 2017. For the twelve months ended December 31, 2018, the net loss was $184.7 million, or $0.50 per share, compared to a net loss of $183.8 million, or $0.63 per share, for the same period in 2017.

Novavax revenue in the fourth quarter of 2018 was $6.1 million, compared to $10.4 million in the same period in 2017. This 41% decrease was driven by the completion of enrollment of participants in the Prepare trial in the second quarter of 2018.

Research and development expenses decreased 13% to $43.4 million in the fourth quarter of 2018, compared to $49.7 million for the same period in 2017. This decrease was primarily due to decreased development activities of ResVax and lower employee-related costs, partially offset by increased development activities of NanoFlu.

General and administrative expenses increased 8% to $9.2 million in the fourth quarter of 2018, compared to $8.5 million for the same period in 2017. The increase was primarily due to higher professional fees.

Interest income (expense), net for the fourth quarter of 2018 was ($2.8) million, compared to ($3.1) million for the same period of 2017.

As of December 31, 2018, Novavax had $103.9 million in cash, cash equivalents, marketable securities and restricted cash, compared to $186.4 million as of December 31, 2017. Net cash used in operating activities for the fourth quarter of 2018 was $45.3 million, compared to $43.4 million for same period in 2017.

About RSV in Infants

Globally, RSV (respiratory syncytial virus) is the leading viral cause of severe lower respiratory tract disease in infants and young children.¹ It is the second leading cause of death in children under one year of age.² Estimated annual hospitalizations of 1.4 million and an estimated 27,300 in-hospital deaths were due to RSV acute lower respiratory infection in children under six months of age.³ RSV results in a total global economic burden of $6.2 billion annually.

In the U.S., RSV is the leading cause of hospitalization of infants.⁴ Estimated annual hospitalizations are up to 76,000.^5,6 While RSV can impact all infants, babies under six months of age are among those at highest risk, as approximately 77% of all first-year RSV infections occur before six months. In the U.S., the total economic burden is $2.7 billion annually.

About ResVax™

ResVax is an RSV fusion (F) protein recombinant nanoparticle vaccine with aluminum phosphate as an adjuvant. It is being developed to protect infants from RSV disease via maternal immunization, which may offer the best method of protection from RSV disease in infants through the first months of life. In February 2019, Novavax announced top-line data from Prepare™, a global Phase 3 clinical trial in 4,636 pregnant women, at least 3,000 of whom have received the vaccine, and their infants. Prepare is supported by an $89.1 million grant from the Bill & Melinda Gates Foundation (BMGF).

About Influenza

Influenza is a world-wide infectious disease that causes illness in humans with symptoms ranging from mild to life-threatening or even death. Serious illness occurs not only in susceptible populations such as infants, young children and older adults, but also in the general population largely because of infection by continuously evolving strains of influenza which can evade the existing protective antibodies in humans. An estimated one million deaths globally each year are attributed to influenza.⁷ Current estimates for seasonal influenza vaccine growth in the top seven markets (U.S., Japan, France, Germany, Italy, Spain and UK), show a potential increase from approximately $3.2 billion in 2012-13 season to $5.3 billion by the 2021-22 season.⁸

About NanoFlu™and Matrix M™

NanoFlu is a recombinant hemagglutinin (HA) protein nanoparticle influenza vaccine produced by Novavax in its SF9 insect cell baculovirus system. NanoFlu uses HA protein amino acid sequences that are the same as the recommended wild-type circulating virus HA sequences. NanoFlu contains Novavax’ patented saponin-based Matrix-M adjuvant, which is potent and well- stimulates both high quality and durable antibody responses as well as multifunctional CD4 and CD8 T-cell responses. In January 2019, Novavax announced positive top-line data from its Phase 2 clinical trial in older adults of quadrivalent formulations of NanoFlu in 1,375 healthy older adults across clinical sites in the U.S.

About Accelerated Approval

Accelerated approval may be granted for certain biological products that have been studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments. Such an approval will be based on adequate and well-controlled clinical trials establishing that the biological product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit. For seasonal influenza vaccines, the hemagglutination inhibition (HAI) antibody response may be an acceptable surrogate marker of activity that is reasonably likely to predict clinical benefit. To be considered for accelerated approval, a biologics license application for a new seasonal influenza vaccine should include results from one or more well-controlled studies designed to meet immunogenicity endpoints and a commitment to conduct confirmatory post-marketing studies of clinical effectiveness in preventing influenza.
