APPLICATION OF THE GUIDELINES

Summary:

The introductory price of Gardasil was found to be within the Guidelines because the price in Canada did not exceed the median of the prices of the same drug in those countries listed in the Patented Medicines Regulations, 1994 (Regulations) in which Gardasil was sold.

Scientific Review:

Gardasil is a new active substance and the PMPRB´s Human Drug Advisory Panel (HDAP) recommended that Gardasil be classified as a category 2 new medicine. It is a breakthrough medicine as it is the first drug product sold in Canada that addresses effectively both the prevention of infections with HPV types 6, 11, 16 and 18 and the associated precancerous cervical, and external genital lesions.

The HDAP did not identify any comparators for Gardasil. There is no drug therapy or vaccine indicated or used for the prevention of HPV and its associated precancerous lesions.

Price Review:

Under the Guidelines, the introductory price of a new category 2 drug product will be presumed to be excessive if it exceeds the prices of all comparable drug products, based on a Therapeutic Class Comparison (TCC) test, and the median of the international prices identified in an International Price Comparison (IPC) test. See the PMPRB´s Compendium of Guidelines, Policies and Procedures for a more complete description of the Guidelines.

It was not possible to conduct a TCC test as the HDAP did not identify any comparator drug products. At introduction, the price of Gardasil was within the Guidelines as it did not exceed the median of the international prices identified in an IPC test.

Where comparators and dosage regimens are referred to in the Summary Reports, they have been selected by the PMPRB Staff and the HDAP for the purpose of carrying out the PMPRB´s regulatory mandate, which is to review the prices of patented medicines sold in Canada to ensure that such prices are not excessive. The publication of these reports is also part of the PMPRB´s commitment to make its price review process more transparent.

The information contained in the PMPRB´s Summary Reports should not be relied upon for any purpose other than its stated purpose and is not to be interpreted as an endorsement, recommendation or approval of any drug nor is it intended to be relied upon as a substitute for seeking appropriate advice from a qualified health care practitioner.
