Grant reviewers have delivered a harsh
message in the latest $243 million research round at the California
stem cell agency – at least that is one way to look at it.
In effect, they told the governing
board of the $3 billion enterprise that the overwhelming majority of
applicants in its signature disease team round do not measure up,
despite the fact that CIRM had early on partially vetted their
efforts. Indeed, the reviewers said that the researchers deserve only
$113 million instead of the full $243 million that was budgeted.
Obviously the results of the review can
be interpreted in other ways as well. But the review outcome should
raise some flags within the stem cell agency and its 29-member board,
which meets tomorrow in Burlingame. It may not auger well for future rounds that also involve CIRM's newly energized drive to push research into the clinic.
One interpretation of the review
results could well be that CIRM's goals are unrealistic, that the
agency is trying to move too fast for the normally glacial pace of
research and development. Another interpretation is that the science
is not good enough in California to accomplish what the agency is
seeking to do, a view expressed by some in the early days of the
nearly 9-year-old program. Another is that the reviewers themselves
don't know enough or have failed to do their homework, which some of
the rejected applicants have argued in their appeals. Yet another is
that the CIRM review process is inadequate to the task of meeting
CIRM's goals. And still another interpretation is that the normal
peer review process on which CIRM's procedures are based is mightily
flawed, a general contention argued by some(See here, here and here.)
Or quite possibly the result of the
disease team reviews could reflect a combination of all of the above,
to one degree or another.
Little is known about the substance of what goes on during the grant review process, aside from the staff-written review summaries. Even CIRM board members, who see only the summaries, have complained from time to time about not having enough information to make a good judgment on an application. Reviews are conducted behind closed doors. Information about the economic and professional interests of reviewers is withheld from the public by the stem cell agency.
Here is a look, however, at what we do know. Initially the
universe of applicants in this round totalled 36. That was the
number that applied for planning grants for this round. Without a
planning grant, they could not apply for a full $20 million award,
with some exceptions. The exception process was controlled by CIRM
President Alan Trounson, not reviewers. CIRM used the planning grants and the exception process not
only to assist applicants but to winnow out weak applications.
Nineteen researchers won planning
awards. With exceptions included and minus dropouts, 22 applied
later for the big money. Out of the 22, only
six were recommended for funding by reviewers, who are known more or less
formally as the Grants Working Group. (See the four items at the
end of this piece for a list of reviewers involved.)
In the past, reviewers have sometimes
not approved sufficient applications to consume the entire amount
budgeted for a round. But they have never produced a shortfall as
great as in this case. It is all the more dramatic since this
round carries a lot of weight for CIRM, which is pushing hard to
commercialize research and fulfill at least part of the promises that
were made to California voters in 2004 to win approval of creation of
the stem cell agency.
One reflection of the unusual nature of
the round is
the record pace of researchers' appeals of negative
decisions by reviewers. At least nine of the 15 rejected scientists
are willing to say publicly that something is is not quite right in the review process, ranging from missing facts to inconsistencies in
CIRM's endorsement of particular paths of research.
It is safe to say that CIRM directors
tomorrow will pluck some applications out of the reject bin and
increase the total awarded. But they should also examine the process
to determine what generated this particular outcome. The Institute of
Medicine, which is currently engaged in a $700,000 examination of
CIRM, also might scrutinize this round with some care, given its size
and importance to the California stem cell research effort.
