Analyst · Sterne Agee
Thank you, Todd. Good afternoon. Thank you, all, for joining us for our business update call. During this call, I will provide you with a business update, and then I will open the call for questions. Before I get into the prepared remarks, I would like to pass along my regards -- or regards from Eric Rose. Eric and I were both planning on being on this call, but Eric has come down with a stomach bug. All of us are subject to getting stomach bugs, and today is his day. So we look forward to Eric joining us for the next call. He's unable to join us for this call.
I'd like to start by saying that we are excited about SIGA's future. We believe that we have built a strong, efficient foundation, and we believe there will be opportunities to grow our foundation. The Arestvyr business is the center of our current foundation. In 2013, the Arestvyr business achieved many important milestones. Let me name a few.
In March of 2013, we made the first delivery of Arestvyr to the Strategic National Stockpile. This is a major achievement as Arestvyr's a novel small-molecule drug that addresses a very serious biothreat. This achievement was made possible by coordinated progress among our science team, our operations team, our regulatory team and our management team. Our proven ability to coordinate a successful R&D and commercialization effort is a rare and valuable asset.
In the third quarter of 2013, we surpassed the 500,000-course delivery threshold, allowing us to receive payments from the government for product deliveries. Since surpassing this threshold, we have received $96 million from the government for the deliveries of Arestvyr.
The third thing I'd like to recap is in total, we have delivered approximately 920,000 courses of Arestvyr to the SNS in 2013. We received payments from the government for approximately 725,000 courses that were delivered. And in accordance with the BARDA contract, the other 195,000 courses were delivered at no cost to the government. As a quick reminder, 300,000 courses in total are expected to be delivered to the SNS at no cost to the government, in accordance with the BARDA contract.
As I recapped, you can see that 2013 was an important year. And in 2014, we expect to maintain momentum within the Arestvyr business. In February, we delivered approximately 256,000 courses of Arestvyr, approximately 192,000 courses were invoiced and the remainder are free. Between now and the end of the first quarter of 2015, we expect to deliver an addition of approximately 825,000 courses of Arestvyr, with the preponderance of the courses to be delivered in 2014. This would bring total deliveries to 2 million courses, which is the delivery number specified in the current BARDA contract. It should be noted that product deliveries planned to 2014 and the first quarter of 2015 are expected to generate gross cash proceeds of $129 million.
In addition to making deliveries of Arestvyr courses under the current BARDA contract, there is a regulatory component of the Arestvyr business. With funding from BARDA, we have been conducting development activities for Arestvyr, working toward the goal of FDA approval. Current or planned development activities for Arestvyr include rabbitpox efficacy studies in rabbits and an expanded clinical safety trial. These studies, as well as other studies, are guided by the results of the December 2011 FDA Advisory Committee recommendation and take into account periodic subsequent meetings and communications with the FDA.
Underpinning our development path is the Animal Efficacy Rule, which is a complex framework. Within that complex framework, we are making diligent progress, and we always maintain an eye toward moving regulatory activities forward as quickly as possible.
Up to this point, I have focused the conversation on the Arestvyr business. Let me now discuss tangible steps that have been taken, or are being taken, to build upon our business foundation. We want to broaden and build upon our foundation. To that end, the optimization program announced late last year and the ongoing partnering process for our preclinical development programs are tangible steps toward expanding and broadening SIGA's foundation. The purpose of the optimization program is to organize resources and emphasize an efficient cost base in an effort to support growth investments to be made in the future and support the Arestvyr infrastructure.
The purpose of the partnering process is to extend the footprint of SIGA by partnering preclinical programs such as the dengue program with companies who have long-term scientific horizons and are broadly committed to the development of preclinical drug candidates.
With the implementation of the optimization program and the planned partnering of preclinical antiviral assets, we are positioning SIGA for growth and long-term value creation. With an efficient infrastructure and a flexible resource base, SIGA has the focus and resources to pursue multiple avenues of value creation.
For instance, SIGA has the focus and resources to pursue further opportunities within the Arestvyr business. Whether it's new, domestic or international government contract for oral therapeutic Arestvyr, or new indications or forms of administration for Arestvyr. Separately, SIGA also has the focus and resources to pursue opportunities outside of the Arestvyr business such as acquiring or in-licensing attractive clinical space development programs. We believe initiatives such as these can expand and broaden SIGA's foundation. And importantly, can lead to value creation for shareholders.
This concludes our prepared remarks in SIGA's business. Before I turn the call over to questions, let me provide a quick update on our litigation with PharmAthene. On January 15 of this year, after briefing on relevant issues, the parties appeared for oral arguments at the Delaware Court of Chancery regarding what, if any, remedies the Chancery Court should impose in light of last year's remand by the Supreme Court of Delaware. The case is currently under review by the Court of Chancery. As noted in our Form 10-K, no assurances can be given as to the Chancery Court's determinations on remand. We will have no further comments about the case during this call.
This concludes our prepared remarks. Thank you for joining this Investor Call. We will now open the line for questions.
