Dukoral™ is classified in the WHO ATC index 2003 as a member of the 4th level ATC class J07AE: vaccines; cholera vaccines, and is the first entry in this class to be introduced in Canada. Dukoral™ (DIN 02247208) is supplied in vials containing one dose of vaccine (1mg Recombinant cholera toxin B subunit per dose; 250 m Vibrio cholerae Inaba 48 classical biotype, heat inactivated, per dose; 250 m Vibrio cholerae Inaba 6973 E1 Tor biotype, formalin inactivated, per dose; 250 m Vibrio cholerae Ogawa 50 classical biotype, formalin inactivated, per dose, and 250 m Vibrio cholerae Ogawa 50 classical biotype, heat inactivated, per dose).
1.3 Canadian Patent 1,340,577 pertaining to Dukoral™ was granted to Vitec AB Sweden on June 1, 1999 and will expire on June 1, 2016. Sanofi Pasteur Limited is the patentee for purposes of the Patented Medicine Prices Review Board (PMPRB).
1.4 Health Canada issued a Notice of Compliance for Dukoral™ on February 21, 2003. Sanofi pasteur began selling Dukoral™ on April 23, 2003.
2. Application of the Excessive Price Guidelines
2.1 The PMPRB's Human Drug Advisory Panel (HDAP) recommended that Dukoral™ be classified as a category 3 new medicine. For the prophylaxis of traveller's diarrhea, the HDAP recommended trimethoprim/sulfamethoxazole, ciprofloxacin and norfloxacin as comparators.
2.2 In accordance with the PMPRB's Excessive Price Guidelines (the Guidelines), Board Staff conducted the review of the price of Dukoral™. A Therapeutic Class Comparison (TCC) test and an International Price Comparison (IPC) test were conducted. The results of the IPC test indicated that the introductory price of Dukoral™ of $28.5206 per vial appeared to exceed the maximum non-excessive (MNE) price of $25.1842 by 13.2% based on the highest international price, namely the U.K. At the time of introduction in 2003 Dukoral™ was sold in Sweden and the U.K. Dukoral™ is presently sold in France, Germany, Italy, Sweden and the U.K.
2.3 The price review results showed that the average transaction price (ATP) of Dukoral™ continued to exceed the Guidelines in 2004 and the first half of 2005, such that cumulative excess revenues as of June 30, 2005 totalled $481,198.49.
2.4 The MNE prices for 2004 and 2005 are $25.7383 and $25.9901 respectively. Assuming that the Canadian price does not become the highest of the comparator countries, the 2006 MNE price would be $26.6449.
