Thanks, John. Good morning, everyone. I'm pleased to report to you that once again we had a very productive quarter. I'd like to take a few minutes to review our key accomplishments before Fred reviews our financial results.
The most visible achievement in the first quarter was our launch of a Phase II dose ranging 500 subject clinical trial, with our trivalent and quadrivalent seasonal VLP influenza vaccine candidates. This is a key milestone for our seasonal flu vaccine program. We're conducting the trial in Australia because the flu season in the southern hemisphere hasn't started yet, which allows us to evaluate our flu vaccine without waiting for the end of the flu season, here in the northern hemisphere. In this trial, we're evaluating immunogenicity and safety of 3 dose levels of our quadrivalent vaccine in healthy adults between the ages of 18 and 64. The goals of the trial are to allow us to transition from a trivalent to a quadrivalent seasonal vaccine candidate and to determine the most effective and appropriate dose for later clinical evaluation. From a timing perspective, we are on plan and expect to report top line clinical data from this trial in the third quarter.
As I mentioned, we initiated this Phase II trial in Australia under the company's trivalent IND with the FDA, rather than waiting to conduct the trial under new quadrivalent IND, which we plan to file later this year prior to the initiation of our next Phase IIb dose confirmation trial.
From a financial reporting perspective, this decision means that we will record a revenue associated with these outside clinical trial costs when we submit the trial data under the new quadrivalent IND later this year and as reviewed by the FDA. This is a timing issue and Fred will discuss the details and impact to our financials later.
This week, we also announced that we have launched the first of 2 Phase I clinical trials of our H5N1 pandemic influenza vaccine candidate, using an adjuvant in 333 adults, 18 to 49 years old. This randomized observer blind dose ranging placebo-controlled trial is also being conducted under our contract with BARDA. We continue to be on track to also launch the second Phase I clinical trial using the same clinical protocol design but with a second different adjuvant. At the conclusion of both Phase I trials, we will select one of the adjuvants and move in to the next stage of pandemic clinical development.
Turning to our RSV program. In March, we presented the results from the Phase I trial of a recombinant nano particle vaccine candidate against RSV, respiratory syncytial virus, at the 14th International Symposium on viral infections. Short-term and 6-month safety and immunogenicity data from this study, suggest the vaccine has a potential to elicit protective immunity from RSV. You may recall that last October, we presented interim top line data from the trial at the Fifth Vaccine in ISV Annual Global Conference, which were consistent with preclinical studies and show that the vaccine was well tolerated and had no systemic side effects. We are very excited about the results and the future potential of this vaccine candidate as a prophylactic solution for RSV in both the pediatric and elderly populations.
Our continuing analyses of the data confirms that our vaccine has the potential to uniquely stimulate antibodies at high levels, that mimic the activity of an improved monoclonal antibody therapy, known as Synagis, made by MedImmune for the potential of RSV in premature infants. We plan to advance our RSV vaccine candidate into 2 Phase II trials in both elderly adults and women of childbearing age. These separate trials will be conducted with and without an adjuvant, and will provide both safety and immunogenicity results in these different age of populations. As I've said before, RSV represents one of the biggest vaccine markets globally by our estimates, greater than $5 billion and this is a product that could be the first RSV vaccine brought to market.
Switching topics to CPL Biologics, our joint venture in Canada, not Canada, in India, with Cadila Pharmaceuticals, CPLB has been making great progress in recent months with the development from new vaccines in its new fully complete vaccine manufacturing facility in India. CPLB is now preparing to begin clinical testing of a VLP-based influenza vaccine and a new rabies vaccine. Both of these vaccine candidates were initially developed at Novavax and transferred to CPLB for scale up and testing. CPLB is in the process of getting regulatory approvals for testing these vaccines in clinical trials in India.
I remind you that we share in their success and can utilize CPLB's development work of vaccine candidates like rabies, to initiate similar efforts in other territories that would benefit from such a program. As we've mentioned, Novavax has worldwide rights outside of India to vaccines developed by CPLB. CPLB is a valuable long-term strategic partner and we congratulate them on their success in expanding our vaccine and development capability, and global manufacturing capacity.
And as a final comment, I wish to acknowledge the appointments of Merv Hamer, as Vice President of Manufacturing; and the promotion of John Herrmann, as Vice President, General Counsel. They are both very talented executives and we're delighted to have them on our senior management team.
I'll now turn the remarks over to Fred.
