Cost of Sales was $832,723 for the quarter compared to $429,080 in 2011 due to higher sales. Operating Expenses were $1,159,533 million compared to $1,117,974 million for the same period in 2011, or a 3.7% increase due to increased financing costs. Expenses for pipeline development continued to decline as the Company advances these assets towards commercialization with its partners. These results have contributed to a lower operating loss for the quarter of $517,745 compared to $734,360 for the same quarter last year.

Subsequent to the First Quarter, a letter of intent was signed with Zydus Cadila, an innovative global pharmaceutical company that discovers, develops, manufactures and markets a broad range of healthcare products, to collaborate on the return of Urokinase to the market. Under terms of the arrangement, all costs associated with the re-launch of urokinase will be covered by Zydus. After product launch, Microbix will also receive a guaranteed margin on all product shipped to Zydus, plus a royalty on all sales made by Zydus.

William J. Gastle, Chief Executive Officer, said “I am very pleased that Urokinase will be re- established as an option for clinicians for treatment of blood clots and related conditions. This is a credit to the safety and efficacy of the molecule, and Microbix’ untiring efforts to restore a much valued therapy to the medical community. For Microbix and Zydus, significant financial benefits will accrue in a much shorter time frame than typically the case with the launch of completely new drugs or new biologics.”

Gastle added, “We continue to strive to build shareholder value across all business units by maximizing manufacturing efficiency and sales growth, strengthening our intellectual property assets, and building pipeline product partnerships to implement those assets.”
