MADRID—The US Food and Drug Administration (FDA) tends to approve cancer drugs faster than Health Canada and the European Medicines Agency (EMA),
according to a study presented at the ESMO 2014 Congress.
On average, the FDA approved antineoplastic agents about 6 to 8 months faster than the EMA and Health Canada, researchers found.
One of the drugs studied had been FDA-approved for more than 4.5 years before the EMA and Health Canada authorized its use.
The researchers said these results suggest a need for a coordinated international approach to reduce the disparity in approval times.
“There needs to be a dialogue amongst industry, regulatory agencies, patient bodies, [the] research community, and oncology professionals on how best we can reduce the time to approval while ensuring safety for approved drugs,” said study investigator Sunil Verma, MD, of Sunnybrook Odette Cancer Center in Toronto, Canada.
A previous study, published in NEJM in 2012, showed that, between 2001 and 2010, the FDA tended to approve all types of drugs faster than the EMA and Health Canada.
Dr Verma and Nardin Samuel, an MD/PhD student at the University of Toronto, focused their study on cancer drugs and presented their findings at ESMO as abstract 1036O_PR.
The pair analyzed approval data for 41 antineoplastic agents and found the average time to FDA approval for these drugs was 6 months shorter than for the EMA and 7.6 months shorter than for Health Canada.
Azacitidine, which is approved to treat hematologic malignancies, had the greatest delay between FDA and Health Canada approval, at 66.1 months. The EMA approved azacitidine 10.3 months earlier than Health Canada but 55.8 months after the FDA.
The fastest approval time among the drugs studied was for cabazitaxel, which was approved for metastatic prostate cancer by the FDA just 17 days after the drug’s manufacturer filed for approval. In Canada and the European Union, the times to approval for cabazitaxel were 11.63 months and 11.03 months, respectively.
“It is not clear why there were these differences, but they are of some concern . . . ,” said David Cameron, MD, of the Edinburgh Cancer Research Centre in the UK, who was not involved in this research.
“[T]hey suggest that, in the absence of data to the contrary, there may be bureaucratic rather than medical/scientific reasons for differential geographical approval timelines, which, of course, will lead to differential geographical benefits from new agents.”
Dr Cameron added that more work is needed to understand the reasons for these differences, as well as assess any potential impact on patients.
