- Provides Update on Seasonal and Pandemic Influenza Programs -

QUEBEC CITY, Nov. 9, 2012 /PRNewswire/ - Medicago Inc. (TSX: MDG)(OTCQX: MDCGF), a biopharmaceutical company focused on developing highly effective and competitive vaccines based on proprietary manufacturing technologies and Virus-Like Particles ("VLPs"), today announced its operational and financial results for the third quarter ended September 30, 2012. The Company's financial statements and management report are available at www.sedar.com and at www.medicago.com.

"In the third quarter of 2012, we announced that we had successfully produced significantly more than 10 million doses of H1N1 influenza VLP vaccine at our commercial-scale facility in North Carolina and completed the DARPA project. In addition, we announced FDA authorization to initiate a Phase I clinical trial with IDRI for an H5N1 VLP vaccine to explore the possibility of enhanced protection with one dose of vaccine, continued development of the quadrivalent seasonal flu vaccine, and signed a commercial agreement with Philip Morris Products for influenza vaccines in China," said Andy Sheldon, President and Chief Executive Officer of Medicago. "In 2013, we expect to see results from at least three clinical trials, which would reinforce our position with governments and companies to secure revenues and grant opportunities."

Corporate and Financial Highlights
During the third quarter of 2012:

• Announced the successful production of significantly more than 10 million does of H1N1 VLP influenza vaccine candidate in one month.  Under our agreement with the Defense Advanced Research Projects Agency ("DARPA"), this earned Medicago a US$1 million milestone payment. Testing by a third party laboratory confirmed that a single dose of the H1N1 VLP induced protective levels of neutralizing antibodies in an animal model. Medicago met all milsteones and has earned the full US$21 million in DARPA milestone awards.
• Medicago signed a licensing agreement with Philip Morris Products SA ("PMP"). Under the agreement, Medicago granted PMP an exclusive license to develop, commercialize and manufacture Medicago's pandemic and seasonal influenza vaccines for China.  In addition, Medicago signed an exclusive, worldwide license for a portfolio of plant-based protein development technologies from PMP for $0.7 million. Medicago received an upfront payment of US$4.5 million from PMP.  In addition, Medicago is eligible to receive development milestone payments totalling US$7.5 million, as well as royalty payments on future sales.
• The Infectious Disease Research Institute ("IDRI"), a Seattle-based non-profit research organization and Medicago announced clearance from the U.S. Food and Drug Administration to initiate a Phase I clinical trial for an H5N1 pandemic Influenza VLP vaccine candidate ("H5N1 VLP vaccine"). The trial is focused on evaluating the safety and immunogenicity of the H5N1 VLP vaccine, combined with IDRI's Glucopyranosyl Lipid A ("GLA") adjuvant, administered intramuscularly ("IM") or intradermally ("ID"). The trial is believed to be the first human test of an intradermal adjuvant - a technology platform that could potentially benefit a number of worldwide vaccination programs. The trial is funded by a multi-million dollar grant IDRI received from DARPA to develop an influenza vaccine for pandemic flu.

Subsequent to the third quarter:

• Medicago and Cellectis plant sciences, a US-based subsidiary of Cellectis Group (Alternext: ALCLS), ("Cellectis"), a specialist in genome engineering, successfully completed the first step in their research collaboration to improve therapeutic proteins produced in tobacco plants. Cellectis develops enzymes called nucleases which can enable the production of biosimilar products.

Update on H5N1 Pandemic Influenza Program
The pandemic threat from H5N1 Avian Influenza remains a serious global threat.  Recent studies by Fouchier and Kawaoka in Science and Nature¹ have demonstrated that by recombining already circulating strains, human to human transmission is possible. These authors have also demonstrated that five mutations are needed for human to human transmission, and that current H5N1 strains circulating in birds are three mutations away from becoming transmissible to humans, strongly supporting the need for pandemic preparedness².

Medicago is therefore expanding its H5N1 clinical program to ensure the continued development of this best-in-class vaccine.  The Company believes that this will provide Medicago with enhanced access to future government contracts and grants for pandemic preparedness. Government contracts may include participation as a domestic supplier in Canada, the U.S., as well as in Europe and Asia. Grant opportunities include the Biomedical Advanced Research and Development Authority (BARDA) Broad Agency Announcement for the Advanced Development of Medical Countermeasures for Pandemic Influenza and other U.S. funding opportunities.

This clinical trial is expected to start in the spring of 2013. This trial will be designed to determine the lowest dosage possible by both IM and ID routes and by combining the vaccine with a GLA adjuvant from IDRI.  Initial safety and immunogenicity data are expected in the summer of 2013, with ongoing results due later in the year. Manufacturing of the H5N1 vaccine candidate for the trial will occur at Medicago's pilot facility in Quebec City. The trial will be designed to demonstrate that: (1) the dosage of H5N1 vaccine can be reduced, thereby effectively increasing capacity and reducing the cost of goods of our pandemic vaccine; (2) Medicago's H5N1 vaccine has the capacity to cross-protect against different strains of H5N1, an important advantage as strains can mutate during a pandemic; and, (3) as ID administration will be tested, this could simplify vaccine distribution and administration during a pandemic. The Company has already shown protection in animal models after one dose of vaccine.  Medicago will now continue to explore the possibility of enhanced protection with one dose of vaccine in humans.  Additional details will be provided at a later date.

Update on Seasonal Influenza Vaccine Program
Medicago is currently preparing for a Phase IIa clinical trial of its quadrivalent seasonal influenza vaccine candidate.  As part of the development of the vaccine, the Company completed different pre-clinical studies. In two animal models, the quadrivalent VLP vaccine was found to be safe and immunogenic, inducing antibody levels comparable to licensed vaccines and allowing for the progression to the production of the clinical lots. The production of the vaccine was initially planned to occur at our pilot facility in Quebec, however the Company has decided to transfer the production to the commercial-scale facility in North Carolina.  This transfer will provide additional capacity at the pilot facility in Quebec, allowing for accelerated production of H5N1 vaccine for the new clinical study, rotavirus, rabies, and other vaccine candidates including at least two additional targets related to Medicago's strategic alliance with Mitsubishi Tanabe Pharma Corporation.

As the North Carolina facility was intended to produce the seasonal influenza vaccine candidate for the Phase IIb clinical trial, it is expected that there will be no impact on the projected time to market as the transfer would have occurred later for the Phase IIb trial. Following successful completion of Phase II and Phase III clinical trials, Medicago anticipates that its quadrivalent seasonal influenza vaccine would receive FDA approval in 2016. At that time, it is estimated that the U.S. market for seasonal influenza vaccines will be valued at US$2 billion. Technology transfer from Quebec to North Carolina is ongoing and production has begun.  Interim data from the clinical trial is now expected to be available in summer 2013.

Corporate Outlook
Expected milestones include:

• Additional contract opportunities (government, pharmaceutical companies);
• Addition of new pipeline candidates;
• Interim data from IDRI Phase I clinical trial in the first quarter of 2013;
• Preparation for pandemic readiness clinical trial for H5N1 pandemic influenza vaccine with interim data expected in summer 2013; and
• Preparation for US Phase IIa clinical trial for quadrivalent seasonal influenza vaccine with interim data expected in summer 2013.

Financial Results
The consolidated loss for the three-month period ended September 30, 2012, was $4,748,832 or $0.02 per basic and diluted share.  This compares to a loss of $4,407,058 or $0.03 per basic and diluted share for the three-month period ended September 30, 2011.  Operating expenses were $9,440,652 in the three-month period ended September 30, 2012, compared to $4,594,871 in the same period of 2011.  The increase in operating expense of $4,805,781 is mainly explained by: (1) the preparation for the Phase IIa clinical trial of the quadrivalent influenza seasonal vaccine; (2) preparation and beginning of the production of H5N1 pandemic vaccine quantities for our upcoming clinical trial; (3) work on our new rabies vaccine and other potential targets; and (4) work on the rotavirus candidate as part of our collaboration with Mitsubishi Tanabe Pharma Corporation.
