11/4/03 FINAL MINUTES
. INITIAL
REVIEW:
(A) Principal
Investigator:
Protocol Title: Effects of Single Dose of dextroamphetamine
in Attention Deficit Hyperactivity
Disorder
Protocol summary: This study
includes a double-blind, placebo-controlled administration of a single low dose
of oral dextroamphetamine (10mg) in 14 healthy control children, 14 ADHD
children and 12 pairs of monozygotic and dizygotic children discordant for
ADHD. An fMRI will follow the medication
administration to examine differences between groups.
NOTE: Prior to the
meeting Dr. Rosenstein circulated a report from NHRPAC (National Human Research
Protections Advisory Committee) clarifying specific portions of 45 CFR 46
Subpart D that governs Children’s Research.
DISCUSSION:
[This protocol was initially
discussed at the 10/28/03 IRB meeting, at which time the board voted to resume
discussion on the protocol at the next IRB meeting. This protocol was the first item on the agenda for the meeting.]
DISCUSSION
IN EXECUTIVE SESSION:
At the previous meeting the board
had deferred a final vote on this protocol to the Nov. 4th meeting.
The discussion resumed with individual board members providing their
perspective on this issue related to the risk assignment for this study. The following notes summarize the views
expressed:
·
The
Common Rule for the protection of human research subjects (45 CFR 46) defines
minimal risk as being “not greater than…those ordinarily encountered in daily
life.” One member suggested that
exposure of healthy children to similar medications is common, particularly
with the prevalence of ADHD in children who are prescribed stimulant
medications for symptoms of ADHD or difficulties in school. Presumably a percentage of these children
may not actually have ADHD and are erroneously prescribed the medication. Thus, in the mind of this member the study
could be considered minimal risk.
·
Another
member identified that one of the board’s concern was the potential to put
subjects at risk for subsequent experimentation/abuse of these stimulant
medications. This member suggested that
the board could make stipulations that would make this risk more explicit in
the consent forms but still permit the approval of this study as minimal risk.
·
A
third member expressed concern that there is very little known regarding the
risk of a single dose of dextroamphetamine in healthy children. In the absence of data establishing the
risks, one member suggested the board should err on the side of subject
protections and forward this protocol to the 407 panel for review.
·
The
concern regarding the potential for later abuse of similar substances based on
this single exposure was also discussed.
Is it possible that a single exposure to dextroamphetamine might somehow
reset a subject’s physiology and thereby increase their susceptibility toward a
tendency of abuse? This did not seem
likely to the member raising the issue, but it remains an unknown. Another member posed that the board could
stipulate that this “unknown risk” be clearly outlined in the consent forms
thus making the study approvable as a minimal risk study.
·
Members
of the board expressed concern regarding the amount of compensation for
subjects participating in this study (total possible study compensation:
$570).
·
One
member felt giving a child a controlled substance (in the absence of a medical
indication) could not be justified, and therefore the protocol could not be
approved.
·
Other
members felt that in the absence of relevant data on the risk of subsequent
abuse by subjects, the Board should err on the side of caution and consider
this study to be a minor increment over minimal risk.
DECISION
AND VOTE:
A motion was made to designate this
protocol as a minimal risk study. There
were 5 votes for the motion and 7 votes against the motion, thus the motion
failed.
A motion was made to forward this
protocol to a 407 panel for expert review.
There were 10 votes for this motion and 2 abstentions.
STIPULATIONS:
None, the protocol was tabled for
forwarding to a 407 panel
RECOMMENDATIONS:
None, the protocol was tabled for
forwarding to a 407 panel.
