This is the stat most people have focused on, although it’s not the most consequential one, IMO:
The number of innovative medicines, or new molecular entities, launched globally in 2011 hit a 10-year high of 31, up from 21 in 2010.
Of greater consequence, IMO, is the declining number of phase-3 failures:
…the tally of drugs terminated in the final Phase III stage of clinical trials dropped markedly, to 45 in the last three years from 53 in 2008-2010…
Inasmuch as phase-3 failures are the biggest component of the fully-allocated cost of bringing a successful drug to market, the factoid above is very encouraging indeed.
R&D expenditure on prescription drugs has effectively plateaued in the past four years, after decades of relentless increases… leading drugmakers spent an aggregate $71.05 billion in 2011. That was 2.5 percent more than in 2010, although part of the rise reflected weakness in the dollar, since a large part of global R&D cash is spent in euros and Swiss francs.
