ISOTECHNIKA REPORTS SECOND QUARTER

2013 FINANCIAL RESULTS

Edmonton, Alberta – August 13, 2013 (ISA:TSX): Isotechnika Pharma Inc. (the “Company”) has released its financial results for the second quarter ended June 30, 2013.

Recent Developments

On February 5, 2013 the Company announced that it had signed a binding term sheet (the “Term Sheet”) with privately held Aurinia Pharmaceuticals Inc. (“Aurinia”) for the merger of the two companies, creating a clinical development stage pharmaceutical company focused on the global nephrology market.

The Term Sheet sets forth the main criteria to be incorporated into a definitive merger agreement under which the Company will acquire 100% of the outstanding securities of Aurinia. The merger is expected to be effected by an exchange of Isotechnika shares for securities of Aurinia, resulting in a 65:35 post-merger ownership split between Isotechnika and Aurinia, respectively.

In addition, the Company and Aurinia have negotiated a tripartite settlement with ILJIN Life Science Co., Ltd. (“ILJIN”) pursuant to which, upon the successful completion of the proposed merger, the combined company will re-acquire full rights to voclosporin for autoimmune indications including lupus, and transplantation in the United States, Europe and other regions of the world, outside of Canada, Israel, South Africa, China, Taiwan and Hong Kong. In return, ILJIN will be entitled to receive certain pre-defined future milestone payments in the aggregate amount of $10 million, plus up to $1.6 million upon the combined company reaching certain financing milestones. ILJIN will also own approximately 25% of the issued and outstanding shares of the combined company.

The transaction is subject to certain closing conditions including, among others, the completion of a merger agreement, acceptance and approval by the Toronto Stock Exchange (the “TSX”), and the approval of Isotechnika’s shareholders at the Annual and Special Shareholders Meeting to be held on August 15, 2013.

The consolidation of the intellectual property through the merger and reaching a settlement agreement with ILJIN provides the combined company with a much higher probability of being able to obtain the necessary funding to continue the development of voclosporin for the lupus indication. Further, the combined company will be able to continue to explore strategic global partnership transactions for the transplant indication. Ideally, the company would advance both transplantation and lupus nephritis to optimize shareholder value. A combined company, having both the lupus nephritis and renal transplantation indications under a single corporate umbrella, would likely offer the most commercially attractive opportunity.

The Company, on June 26, 2013 closed the first tranche of a private placement, raising gross proceeds of $1.02 million by the issuance of 22,656,000 units at a price of $0.045 cents per unit. Each unit consisted of one common share and one non-transferable common share purchase warrant exercisable at $0.05 cents for a period of five years from the closing date. The issue of the warrants is subject to shareholder approval. In order to help fund its operations in the immediate-term, the Company received loans in April, 2013 from each of Dr. Richard Glickman, who is a major Aurinia shareholder, and ILJIN consisting of the issuance of zero-coupon promissory notes in the principal amount of $200,000. Dr. Glickman and ILJIN each subscribed for Units in the private placement in the amount of $200,000 each and the promissory notes were cancelled.

Financial Results

The Company reported a consolidated net loss of $993,000 or $0.005 per common share for the three months ended June 30, 2013, as compared to a consolidated net loss of $2.3 million or $0.013 per common share for the three months ended June 30, 2012. For the six months ended June 30, 2013, the consolidated net loss was $1.8 million or $0.009 per common share compared to a consolidated net loss of $2.8 million or $0.016 per common share for the comparable period in 2012.

Revenue decreased to $87,000 for the three months ended June 30, 2013, compared to $90,000 for the three months ended June 30, 2012. The Company recorded revenue of $176,000 for the six months ended June 30, 2013, as compared to $5.9 million for the same period in 2012. The Company, in the first quarter of 2012, recorded license revenue of $4.4 million related to the Development, Distribution and License Agreement (“DDLA”) with ILJIN Life Science Co., Ltd. (“ILJIN”) which had previously been recorded as deferred revenue and also recorded $1.3 million of other revenue on the completion of a sale agreement with its partner, Lux Biosciences, Inc. for previously manufactured Active Pharmaceutical Ingredient.

Research and development expenditures decreased to $452,000 in the second quarter of 2013, compared to $817,000 in the second quarter of 2012. The Company incurred net research and development expenditures of $790,000 for the six months ended June 30, 2013, as compared to $1.6 million for the same period in 2012. The decrease reflects reduced activity, including reduced salary costs, due to the Company’s current limited financial resources.

Corporate and administration decreased to $503,000 for the second quarter of 2013, compared to $991,000 for the second quarter of 2012. The Company incurred corporate and administration expenditures of $1.0 million for the six months ended June 30, 2013, as compared with $2.0 million for the same period in fiscal 2012. Corporate and administration expenses decreased primarily due to lower professional and consulting fees. The Company had incurred higher fees due to consulting services related to strategic alternatives and legal fees related to the termination of the DDLA with ILJIN and the resulting arbitral process in 2012.

Other expense (income) reflected a loss of $43,000 for the second quarter ended June 30, 2013 compared with a loss of $400,000 for the same period in 2012. Other expense (income) reflected a loss of $5,000 for the six months ended June 30, 2013 compared to an expense of $4.6 million for the same period in 2012. Other expense for the six months ended June 30, 2012 included a non-cash loss of $4.2 million on the ILJIN derivative financial instrument. There was no similar item in 2013.
