Health Canada news

Revisions to the Guidance Document: PM(NOC) Regulations published. On April 2, 2012, Health Canada announced the publication of revisions to its Guidance Document: Patented Medicines (Notice of Compliance) Regulations. Section 3.4.1 of the Guidance Document has been updated to reflect the Office of Patented Medicines and Liaison's administration of section 5 of the Patented Medicines (Notice of Compliance) Regulations ("Regulations") in respect of administrative drug submissions (both new and abbreviated) filed where a manufacturer is licensed to sell a drug identical to a marketed drug (also referred to as a cross-referenced submission). Health Canada's view is that such administrative drug submissions will not trigger section 5 of the Regulations (even if a patent is listed on the Patent Register before the licensee files its administrative new drug submission and after the licensor's submission is filed and therefore not required to be addressed by the licensor), and an NOC will be issuable in respect of such a submission only after the licensor's drug submission receives its NOC. The revisions only apply to a manufacturer that has submitted such a submission on or after April 16, 2012. The Guidance Document is substantially the same as the draft published for comment on August 17, 2011.

Patented Medicine Prices Review Board news

New NEWSletter released. The PMPRB has released its April 2012 NEWSletter.

Newsletter.

Proposed changes to the Compendium of Policies, Guidelines and Procedures. The Board is seeking comments on proposed changes to the Compendium of Policies, Guidelines and Procedures by May 14, 2012. The proposed changes include (i) eliminating the 5% investigation trigger, i.e., where the National Average Transaction Price of an existing drug product exceeds the National Non-Excessive Average Price by more than 5%, to avoid a large number of investigations involving excess revenues less than $50,000; and (ii) replacing the three-year period to offset de minimus excess revenues through a Voluntary Compliance Undertaking with a requirement to offset in a timely manner.

Proposed changes, side-by-side comparison of current and proposed text and mailing address for comments.

Recent Court decisions

Patented Medicines (Notice of Compliance) Regulations

Federal Court allows pleading amendment based on alternative process defence. As reported in the January 2012 issue of Rx IP Update, the Court of Appeal affirmed the Trial Judge's finding of infringement of certain batches of lovastatin (Merck's MEVACOR) by Apotex and Apotex Fermentation (collectively "Apotex"). In the reference to determine damages (scheduled to be heard in April 2013), the Prothonotary denied Apotex leave to amend its Statement of Defence to assert that it could have employed a non-infringing alternative process for producing lovastatin and therefore any damages suffered by Merck due to Apotex's infringing process are not damages at all by virtue of the availability of a non-infringing process. Apotex appealed. On April 18, 2012, the Federal Court allowed Apotex's appeal, concluding that Apotex has advanced an arguable and important point of law and that it is not plain and obvious that the alternative process defence cannot succeed, although this argument faces a "formidable obstacle" to succeed.

Merck & Co., Inc. v. Apotex Inc., April 18, 2012.
Federal Court decision — 2012 FC 454.

Federal Court of Appeal affirms that ELOXATIN is an "innovative" drug. As reported in the June 2011 issue of Rx IP Update, the Federal Court dismissed Teva Canada's challenge of data protection for ELOXATIN (sanofi-aventis's oxaliplatin) on the basis of prior approvals under the Special Access Programme ("SAP"). On April 4, 2012, the Federal Court of Appeal dismissed Teva's appeal. The Court of Appeal held that the "magic moment of approval is signalled by the issuance of a notice of compliance and a drug identification number." As a result, drugs for which previous authorizations were granted under the SAP are not considered "previously approved" as that term is used in the definition of an innovative drug.

Sanofi-aventis had cross-appealed the Federal Court's decision holding that Teva had standing to bring the judicial review application and had done so within the appropriate time limit. The Court of Appeal held that a cross-appeal does not lie in this case as the Federal Court's Order does not adversely affect sanofi-aventis. In any event, it held that Teva did have standing to bring the application, which it brought in a timely fashion as the Minister of Health's decision refusing Teva's request to remove ELOXATIN from the Register of Innovative Drugs was a fresh exercise of discretion and susceptible to judicial review.

Teva Canada Limited v. Canada (Health) and sanofi-aventis Canada Inc., April 4, 2012.
Federal Court of Appeal decision — 2012 FCA 106.
Federal Court decision — 2011 FC 507.
