Biosketch:
Dr. DiMasi, who
has been with the Tufts Center since the fall of 1987, focuses his research
activity on the new drug development and regulatory review processes
and the economics of the pharmaceutical industry. His current research
examines the impact of policies and practices to speed the development
and review processes for new drugs, how firms have organized internally
to accommodate the increasing need for pharmacoeconomic studies, the
role that pharmacoeconomic evaluations have played in the R&D process,
the cost of new drug development, and success and attrition rates for
investigational drugs. Dr. DiMasi presents his work at numerous professional
and industry conferences in the United States and abroad and has testified
before the U.S. Congress in hearings leading up to the FDA Modernization
Act of 1997 and reauthorization of the Prescription Drug User Fee Act.
Dr. DiMasi received his Ph.D. in economics from Boston College.
Abstract:
The costs of developing the types of new drugs that have been pursued
by traditional pharmaceutical firms have been estimated in a number
of studies. However, similar analyses have not been published on the
costs of developing the types of molecules on which biotech firms have
focused. This study represents a first attempt to get a sense for the
magnitude of the R&D costs associated with the discovery and development
of new therapeutic biopharmaceuticals (specifically, recombinant proteins
and monoclonal antibodies [mAbs]). We utilize drug-specific data on
cash outlays, development times, and success in obtaining regulatory
marketing approval to estimate the average pre-tax R&D resource
cost for biopharmaceuticals up to the point of initial U.S. marketing
approval (in year 2005 dollars). We found average out-of-pocket (cash
outlay) cost estimates per approved biopharmaceutical of $198 million,
$361 million, and $559 million for the preclinical period, the clinical
period, and in total, respectively. Including the time costs associated
with biopharmaceutical R&D, we found average capitalized cost estimates
per approved biopharmaceutical of $615 million, $626 million, and $1,241
million for the preclinical period, the clinical period, and in total,
respectively. Adjusting previously published estimates of R&D costs
for traditional pharmaceutical firms by using past growth rates for
pharmaceutical company costs to correspond to the more recent period
to which our biopharmaceutical data apply, we found that total out-of-pocket
cost per approved biopharmaceutical was somewhat lower than for the
pharmaceutical company data ($559 million vs. $672 million). However,
estimated total capitalized cost per approved new molecule was nearly
the same for biopharmaceuticals as for the adjusted pharmaceutical company
data ($1,241 million versus $1,318 million). The results should be viewed
with some caution for now given a limited number of biopharmaceutical
molecules with data on cash outlays, different therapeutic class distributions
for biopharmaceuticals and for pharmaceutical company drugs, and uncertainty
about whether recent growth rates in pharmaceutical company costs are
different from immediate past growth rates.
