CRITICAL PATH INITIATIVE SLOWED BY FUNDING SHORTFALLS, CONTROVERSIES
The FDA's Critical Path Initiative, which is supposed to speed the introduction
of new products to market, is being held back by limited agency funding, as
well as several ongoing controversies, according to agency and industry officials.
The agency has long been concerned about the lack of new drugs making it to
market, said Larry Kessler, director of the FDA's Office of Science and Engineering
Laboratories. The FDA believes efforts to introduce new devices can be improved
as well, he said during a recent presentation before the agency's dental products
medical devices advisory panel.
Aiming to speed such products to market, the FDA introduced the Critical Path
Initiative in March 2004, which seeks to use biomarkers and new technologies
to weed out unsuccessful candidates early in the development process. But while
details have become available about the plan since last year, the agency has
yet to implement the initiative. Funding levels have played a role in the delay,
according to Kessler and industry representatives.
Recent controversies over the FDA's relationship with industry have also delayed
the initiative, said Mark Brager, spokesman for the Advanced Medical Technology
Association. For example, the FDA has been under fire for how it handled problems
with Vioxx (rofecoxib) and implantable cardioverter defibrillators (ICDs). Lawmakers
on both sides of the aisle have used these controversies to allege that the
FDA is too close to industry. Such scrutiny only chills any agency efforts to
collaborate with industry, Brager said.
But recent controversies point to the need for greater collaboration, Kessler
said. Problems with ICDs are the "poster child" for development of
a process that ensures products are manufactured with more consistent quality,
Kessler added. Such a process, known as industrialization, along with methods
for assessing safety and effectiveness of products, make up the Critical Path
program.
