Abstract: The selection of appropriate subjects is a critical element of
successful clinical trials. Failure to properly identify, select, and retain
subjects in clinical trials of antidepressant medications may affect the
ability to show separation from placebo. Little is known about which type
of site, academic or nonacademic, is superior in selecting and retaining
appropriate subjects. In the present investigation, the authors conducted
a retrospective analysis comparing the performance of academic and
nonacademic sites in selecting and retaining appropriate subjects in a
recently completed multi-site clinical study of aripiprazole augmenta-
tion. The authors used a set of operationalized criteria called the SAFER
to identify appropriate study subjects. No significant differences were
found in rates of SAFER interview passing, study completion, and clini-
cal outcomes between academic and nonacademic sites. Our findings
suggest that academic and nonacademic sites are equally effective in their
ability to identify and retain appropriate study participants.

ome proportion of drugs being investigated as treatments for
depression is never brought to market because of failure
to demonstrate superior efficacy to placebo in clinical trials.
Among the many proposed reasons for the inability to show
separation from placebo, inappropriate selection and recruit-
ment, trial design
1
as well as inadequate retention of subjects at
clinical sites may be a significant factor. It is critical that sites
participating in clinical trials be able to accurately identify, se-
lect, and retain those patients who are appropriate for inclusion
in a clinical study on the effectiveness of an antidepressant.
Many clinical trials nowadays use a combination of aca-
demic and nonacademic recruitment sites, yet it is not clear
whether either of these is superior in selecting and retaining
appropriate subjects. A literature review through PubMed found
only one study that compared the performance of academic and
nonacademic research sites, specifically in a population with
Alzheimer disease,
2
with the findings favoring the academic
centers. However, no such published studies of treatment of
mood disorders were identified. A similar comparison of aca-
demic and nonacademic centers in the context of psychophar-
macologic clinical trials would therefore be of interest.
In 2008, Targum et al
3
proposed a set of operationalized
criteria known as the SAFER interview to identify patients with
the acute primary symptoms that the novel drug is supposed to
influence. Criteria for the SAFER inventory include an assess-
ment of the following: State versus trait, Assessability, Face
validity, Ecological validity, and Rule of the three P’s (pervasive,
persistent, and pathological). As part of the Clinical Trials
Network and Institute (CTNI) at Massachusetts General Hospital,
our experienced physicians are trained in the administration of the
SAFER and use this instrument for selecting appropriate research
patients after they have been provisionally admitted into a study per
usual admissions criteria.
We recently completed a multi-site clinical study of aripi-
prazole augmentation that included academic and nonacademic
study sites and used the SAFER as a screening instrument.

In
a retrospective analysis, we used the SAFER interview outcomes
to compare the performance of academic sites versus nonaca-
demic sites in selecting and retaining appropriate subjects for the
length of this research trial. Given that nonacademic sites are
often under greater financial pressure to recruit subjects for
clinical trials, we hypothesized that academic sites would have a
more rigorous recruiting standard (as confirmed by a lower rate
of SAFER interview failures) than nonacademic sites and that
the more rigorous selection would result in greater retention
rates as well.
MATERIALS AND METHODS
The parent trial was a 60-day multi-center, double-blind,
placebo-controlled study on the efficacy and tolerability of low-
dose aripiprazole (2 mg/d) augmentation in patients with Major
Depressive Disorder with inadequate antidepressant treatment
(ADT) response.
4,5
The study was conducted in accordance with
rules and guidelines established by the Partners Human Re-
search Committee, and was conducted with approval of the
Partners Human Research Committee Internal Review Board.
Written informed consent was obtained from all participants by a
licensed physician before all study-related procedures.
The primary outcome was the difference in response (decrease
in Montgomery-Asberg Depression Rating Scale [MADRS]
6
total
score of at least 50%) rate using the sequential parallel com-
parison design.
7
In accordance with the sequential parallel de-
sign, the 60-day double-blind treatment was divided into two
30-day phases, with assessments performed every 10 days. After
the 14- to 28-day screening period, eligible patients were ran-
domized to either aripiprazole, 2 mg/d (n = 56), or placebo

The study from which data for the present paper was taken (‘‘A double-blind,
placebo-controlled study of aripiprazole adjunctive to antidepressant
therapy [ADT] among depressed outpatients with inadequate response
to prior ADT [ADAPT-A Study]’’) was an investigator-initiated study
supported by Bristol-Myers Squibb, which provided blinded study
medication. Bristol-Myers Squibb did not have a role in the study design
and in the collection, analysis, or interpretation of data in the
ADAPT-A Study.
Bristol-Myers Squibb had no role in the writing of the present paper or the
decision to submit the paper for publication. The present paper was
submitted for review by Bristol-Myers Squibb before submission
to the Journal of Clinical Psychopharmacology .
