Novavax Reports Fourth-Quarter and Year-End 2013 Financial Results and Initiation of Phase 1/2 Clinical Trial of Its H7N9 Avian Influenza VLP Vaccine Candidate With Matrix-M(TM)

GAITHERSBURG, Md., March 10, 2014 (GLOBE NEWSWIRE) -- Novavax, Inc. (Nasdaq:NVAX), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of recombinant nanoparticle vaccines and adjuvants, today reported its financial results for the fourth quarter and year ended December 31, 2013 and announced the initiation of a Phase 1/2 clinical trial of its H7N9 avian influenza VLP vaccine candidate with its proprietary Matrix-M adjuvant. The trial is enrolling 610 healthy subjects to evaluate the safety and immunogenicity of this vaccine and adjuvant.

Novavax Business Highlights

2013 Achievements:

• Reported data from two RSV F-protein nanoparticle vaccine trials, one in 330 women of childbearing age and the other in 220 elderly subjects, demonstrating strong immunogenicity of the RSV vaccine candidate;
• Demonstrated in the RSV elderly subject trial that the vaccine could be administered concurrently with a seasonal influenza vaccine to elicit potentially protective levels of antibodies to both vaccine targets;
• Initiated our H7N9 avian influenza VLP vaccine candidate program in April and published the industry's first H7N9 vaccine human clinical trial data showing highly protective levels of antibodies following vaccination in the December 26^th issue of the New England Journal of Medicine;
• Acquired Novavax AB (previously Isconova AB) and its saponin-based adjuvant Matrix-M to support Novavax' vaccine programs; and
• Completed a successful $100 million secondary stock offering.

2014 Recent Events:

• Extended the contract for Advanced Development of Recombinant Influenza Products and Pandemic Preparedness with HHS BARDA; and
• Initiated a U.S.-based Phase 1/2 clinical trial of H7N9 avian influenza VLP vaccine candidate with Matrix-M, enrolling 610 healthy adult subjects between 18 and 64 years old, under the Company's HHS BARDA contract.

2014 Anticipated Events:

• Release of top-line data from the ongoing Phase 2 clinical trial of the RSV F protein nanoparticle vaccine candidate in women of childbearing age in the second quarter of 2014;
• Release of top-line data from the recently initiated Phase 1/2 clinical trial of the H7N9 avian influenza VLP vaccine candidate with Matrix-M in the second half of 2014;
• Initiate a Phase 2 clinical trial of our RSV F protein nanoparticle vaccine in pregnant women in the fourth quarter of 2014; and
• Initiate a Phase 2 clinical trial of our quadrivalent VLP seasonal influenza vaccine in the fourth quarter of 2014.

"We made substantial progress in advancing our RSV and influenza vaccine development programs during 2013 and I believe 2014 holds the potential for even greater accomplishments across our entire pipeline," said Stan Erck, president and CEO of Novavax, Inc. "Our rapid response to the emergence of an avian H7N9 influenza strain continues to demonstrate the power and flexibility of our vaccine and adjuvant technologies. This year we plan to report top-line results from our ongoing RSV and influenza studies, initiate our first RSV clinical trial in pregnant women and report top-line results from the first study of our H7N9 avian influenza vaccine candidate with our Matrix-M adjuvant. These will be important milestones for these programs for which I anticipate continued success in 2014."

Financial Results for the Fourth Quarter and Year Ended December 31, 2013

In connection with its acquisition on July 31, 2013, Novavax AB's operations have been included in the company's consolidated results of operations and financial position as of the acquisition date. Novavax reported a net loss of $14.1 million, or $0.07 per share, for the fourth quarter of 2013, compared to a net loss of $8.0 million, or $0.06 per share, for the fourth quarter of 2012. For the full year 2013, the net loss was $52.0 million, or $0.31 per share, compared to a net loss of $28.5 million, or $0.22 per share, for 2012.

Novavax revenue in the fourth quarter of 2013 increased 92% to $8.7 million as compared to $4.6 million for the same period in 2012. The increase in revenue was primarily due to the HHS BARDA amendment relating to H7N9 manufacturing and other activities and the PATH amendment to support the company's Phase 2 clinical trial in women of childbearing age.

Research and development expenses increased 69% to $16.3 million in the fourth quarter of 2013, compared to $9.6 million for the same period in 2012, primarily as a result of increased costs relating to the company's RSV and pandemic (H7N9) influenza clinical trials and higher employee-related costs. General and administrative expenses increased 65% to $4.1 million in the fourth quarter of 2013 as compared to $2.5 million for the same period in 2012, resulting primarily from Novavax AB's expenses and higher professional fees.

As of December 31, 2013, the company had $133.1 million in cash and cash equivalents and investments compared to $50.3 million as of December 31, 2012. Net cash used in operating activities for 2013 was $45.4 million compared to $18.2 million for 2012. The increase in cash usage from the prior year was primarily due to higher research and development spending, including the company's RSV and pandemic (H7N9) influenza clinical trials, as well as increased employee-related costs.
