Application of the Guidelines
The introductory price of Elidel was found to be within the Guidelines because the cost of therapy did not exceed the cost of therapy of existing drugs in the therapeutic class comparison and the price did not exceed the range of prices in other comparator countries where Elidel was sold.
Elidel is a new active substance and the PMPRB's Human Drug Advisory Panel (HDAP) recommended that Elidel be reviewed as a category 3 new medicine (provides moderate, little or no therapeutic advantage over comparable medicines).
The Therapeutic Class Comparison (TCC) test of the Guidelines provides that the price of a category 3 new drug product cannot exceed the prices of other drugs that treat the same disease or condition. Comparators are generally selected from among existing drug products in the same 4th level of the Anatomical Therapeutic Chemical (ATC) System that are clinically equivalent in addressing the approved indication. See the PMPRB's Compendium of Guidelines, Policies and Procedures for a more complete description of the Guidelines and the policies on TCCs.
Of the compounds within the same 4th level ATC class as Elidel, only Protopic (tacrolimus) is both available in Canada and shares the same indication as Elidel. Consequently, the HDAP recommended Protopic as the sole comparator for the purpose of a TCC test for Elidel.
The Guidelines provide that the dosage recommended for comparison purposes will normally not be higher than the maximum of the usual recommended dosage. The recommended comparable dosage regimens for Elidel and Protopic are based on the respective product monographs and supported by clinical literature.
Under the Guidelines, the introductory price of a new category 3 drug product will be presumed to be excessive if it exceeds the price of all of the comparable drug products based on the TCC test, or if it exceeds the prices of the same medicine in the seven countries listed in the Patented Medicines Regulations.
As shown in the table below, the price of Elidel was within the Guidelines relative to the TCC test as it did not exceed the cost per day of the comparable medicine.

In 2003, Elidel was being sold in Germany, Sweden, Switzerland, United Kingdom, and the United States. In compliance with the Guidelines, the price in Canada did not exceed the range of prices in those countries; the price in Canada was second highest above the median international price.
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.
