Under its transparency initiative, the PMPRB publishes the results of   the reviews of new patented drugs by Board Staff, for purposes of   applying the PMPRB´s Excessive Price Guidelines (Guidelines), for all new active substances introduced after January 1, 2002. 
For adults and adolescents (12 years of age and above) with moderate   to severe persistent asthma who have a positive skin test or in vitro reactivity to a perennial aeroallergen and whose symptoms are inadequately controlled with inhaled corticosteroids.
The introductory price of Xolair 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 in which it was sold.
Xolair is a new active substance and the PMPRB's Human Drug Advisory   Panel (HDAP) recommended that Xolair be reviewed as a category 3 new   medicine (provides moderate, little or no therapeutic advantage over   comparable medicines). 
The HDAP did not recommend any comparators for the conduct of a   Therapeutic Class Comparison (TCC) test. Xolair is indicated as an   adjunct to inhaled corticosteroids in a very specific population: those   who have persistent asthma due to aeroallergens despite optimal therapy   with anti-asthma medications.
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 in the TCC test, or if it exceeds the   prices of the same medicine in the seven countries listed in the Patented Medicines Regulations.   The Guidelines further state that when it is inappropriate or   impossible to conduct a TCC test, Board Staff will give primary weight   to 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. 
As no comparable drug products could be identified for the purposes   of conducting a TCC test, the price of Xolair was considered within the   Guidelines as it did not exceed the median of the international prices   identified in an IPC test.
The Guidelines provide that when a medicine is sold in fewer than   five countries at the time of its introduction, the introductory price   will be treated as the interim benchmark price. The interim benchmark   price may be reviewed at the end of three years or when the medicine is   sold in at least five countries, whichever comes first.
