AstraZeneca successful in obtaining prohibition Order against Pharmascience for its generic esomeprazole product

In AstraZeneca Canada Inc et al v Pharmascience Inc et al, 2012 FC 1189, the Federal Court granted AstraZeneca an Order prohibiting the Minister of Health from issuing a notice of compliance (NOC) to Pharmascience Inc. for its generic esomeprazole product, which was compared to AstraZeneca's NEXIUM, until the expiry of Canadian Patent 2,290,531 (’531 Patent).

None of the allegations of invalidity, including inutility of the ’531 patent asserted by Pharmascience, was found to be justified.

Of note, the Federal Court affirmed that there is no requirement to prove utility in the patent — the patent need not provide data for all experiments conducted as proof of utility.

Pharmascience's other allegations of mere discovery, insufficient disclosure and obviousness were also found to be unjustified. The Federal Court held that the ’531 patent provides more information than merely identifying an inherent physiochemical property of a known substance and was not a mere discovery as asserted by Pharmascience. Rather, the ’531 patent "delves" into a property (cloud point) of a formulation component (HPMC) to ensure consistent drug release from the formulation. With respect to non-obviousness, the Court concluded that there are clear differences between the claimed invention, properly construed, and the prior art, and the relevance of the cloud point to drug release was not obvious.

Supreme Court of Canada news

Teva denied leave to appeal pantoprazole decision. On November 1, 2012, the Supreme Court of Canada denied Teva leave to appeal from the Court of Appeal decision (reported in the July 2012 issue of Rx IP Update) affirming the lower Court's decision to strike out portions of Teva's Statement of Claim relating to losses, damages and harm incurred outside the section 8 liability period, including damages for permanent loss of market share, in respect of pantoprazole (Nycomed's PANTOLOC).

Teva Canada Limited v Nycomed Canada Inc et al (SCC Case No. 34873).
Federal Court of Appeal decision — 2012 FCA 129.

Supreme Court addresses tax rules on transfer pricing. On October 18, 2012, the Supreme Court considered the tax rules for setting transfer prices in the context of contractual and intangible property rights. Transfer prices are the prices set between related entities in different jurisdictions for products or services provided to one another. Canadian tax rules apply an "arm's length principle" in considering the reasonableness of a transfer price. The Minister of National Revenue reassessed GlaxoSmithKline Inc. ("Glaxo Canada") for four taxation years on the basis that the transfer prices for ranitidine (the active ingredient in ZANTAC) were higher than would have been reasonable had the companies been dealing at arm's length, having regard to the prices that generic manufacturers Apotex Inc. and Novopharm Ltd. paid for ranitidine from other sources. While the Tax Court affirmed the reassessment, the Federal Court of Appeal reversed and remitted the matter to the Tax Court for redetermination.

The Supreme Court affirmed, holding that the Minister is required to consider all "economically relevant characteristics" in determining the arm's length price for the property. The Supreme Court held that as the prices paid by Glaxo Canada were set in part as compensation to Glaxo Group Ltd. for the rights and benefits conferred on Glaxo Canada under a licence agreement (including, inter alia, patent and trademark rights and guaranteed access to new products and raw materials), that agreement could not be ignored in determining the reasonable amount paid. In addition, the Supreme Court held that there was value in the fact that materials manufactured under Glaxo Group's good manufacturing practices may confer a "certain degree of comfort that the good has minimal impurities and is manufactured in a responsible manner." The Supreme Court therefore remitted the matter to the Tax Court to redetermine the amount that would have been reasonable in the circumstances if Glaxo Canada and the supplier had been dealing at arm's length, having regard to the effect of the licence agreement.

Canada v GlaxoSmithKline Inc, October 18, 2012.
Supreme Court of Canada decision — 2012 SCC 52.
Federal Court of Appeal decision — 2010 FCA 201.
Tax Court of Canada decision — 2008 TCC 324.

Health Canada issues revised draft guidance document: "The Use of Foreign Reviews by Health Canada." Health Canada's pilot project of its use of foreign reviews for determination of market authorization for Canada has been in place since October 2011. Since the inception, Health Canada has received various comments and suggestions for improving the project. As a result, Health Canada has issued a revised draft guidance document and a FAQ.

Draft guidance document. FAQ.

Proposed amendments to Food and Drug Regulations extend GMP requirements to active ingredients. On September 29, 2012, proposed amendments to the Food and Drug Regulations were published that would (i) extend Good Manufacturing Practices (GMP) requirements to active ingredients (AI); (ii) extend the drug establishment licensing (EL) requirements such that they apply to all AI fabricators, packagers/labelers, testers and importers; and (iii) create a new record-keeping requirement to foster the traceability of AI from the original fabricator to the dosage-form drug manufacturer. The deadline for submitting representations is December 13, 2012.

Health Canada has published a draft guidance document for the manufacture of AIs pursuant to the proposed amendments. Interested stakeholders can request a copy from Health Canada. The consultation period runs from October 22, 2012 to January 5, 2013. Health Canada has also published a cost-benefit analysis of the proposed amendments.

Recent Court decisions

Patented Medicines (Notice of Compliance) Regulations

Court of Appeal requires strict product specificity for a medicinal ingredient claim. On October 9, 2012, the Federal Court of Appeal upheld the Federal Court's decision that a patent containing claims for a formulation comprising tenofovir disoproxil fumarate, emtricitabine and a non-nucleoside reverse transcriptase inhibitor (NNRTI) and claims for a combination of such ingredients was not eligible for listing on the Patent Register against its new drug submission for Gilead's COMPLERA. COMPLERA contains tenofovir disoproxil fumarate, emtricitabine and rilpivirine, an NNRTI. The Minister held the patent was ineligible for listing as the patent referenced NNRTIs as a class without specifying rilpivirine. The Federal Court held that the eligibility should be considered pursuant to section 4(2)(b) of the Regulations as containing a claim to a formulation rather than combination claims. The Court, relying on Bayer Inc v Canada (Minister of Health), 2010 FCA 161 (leave to appeal refused, SCC Case No. 33845), and Purdue Pharma v Canada (Attorney General), 2011 FCA 132, held that product specificity had not been met as the claimed formulation and the approved formulation did not match precisely.

The Court of Appeal found that the Federal Court erred in deciding that eligibility depended upon the requirements of section 4(2)(b) (eligibility requirements for a patent containing a claim for the formulation) of the Regulations, rather than section 4(2)(a) (eligibility requirements for a patent containing a claim for the medicinal ingredient). The Court nevertheless dismissed the appeal, finding that the product specificity requirement also applies under section 4(2)(a) and this requirement was not met as the patent claims did not make "specific reference" to the medicinal ingredient rilpirivine but only the broad class of compounds.

Gilead Sciences Canada Inc v Minister (Health), October 9, 2012.
Federal Court of Appeal decision — 2012 FCA 254.
Federal Court decision — 2012 FC 2.
