Clinical Trial Summary
PRECISE-D is a single site, randomized, open label 8-week clinical trial that will enroll 70
participants to evaluate if the level of inflammation in our body can predict how we will
respond to antidepressants. C-reactive protein (CRP) is a substance in the body that is
associated with inflammation. Previous research has suggested that people with high CRP
(i.e., high inflammation levels) tend to have greater improvement of depressive symptoms with
an antidepressant called bupropion, while individuals with low CRP (i.e., low inflammation
levels) appear to have more benefit from selective serotonin reuptake inhibitors
antidepressants (SSRI), such as escitalopram. However, it is not completely clear if CRP can
predict your response to these two antidepressants.
Participants will undergo a screening visit that includes a physical exam, overall health
evaluation, assessment of mental health history, and a toxicology and pregnancy test. Once
screening is complete, participants will be randomized to one of two groups that will
determine whether their CRP levels will be used to select which antidepressant they will
receive. Participants will then complete 4 follow up visits at weeks 2, 4, 6, and 8. A
follow-up phone call from the study team will occur at week 12.
Description:
PRECISE-D is a single site, randomized, open label 8-week clinical trial that will enroll 70
participants. Participants will be asked to attend approximately 5 visits with the
researchers or study staff.
The screening process will take approximately 2 hours, and will include a physical
examination, toxicology and pregnancy test, as well as the completion of assessments. We will
ask participants a series of questions regarding their general health, mental health history,
and any medications they are currently taking. Additionally, some self-report questionnaires
will be used as part of this process. The results of the screening exams, tests, and/or
procedures will be reviewed to determine whether a participant will be allowed to continue in
the study. In the event that there are questions about a participant's eligibility or
screening procedures are remaining, the screening visit may be conducted over 2 visits.
Once eligibility is determined, the baseline visit (Week 0) will be completed. This visit
will last approximately 1 hour and 15 minutes and will include the following:
- Bloodwork: We will obtain levels of CRP and other inflammatory substances. We will also
examine electrolytes, kidney function, thyroid function, lipid panel, blood cell count,
and other tests of general health.
- Self-Report Questionnaires: Participants will complete 8 questionnaires. These include
questions about mental health and mood. The questionnaires range from 5 to 20+ items.
- Cognitive tests: We will examine the participant's attention, memory, and cognition
using a series of computerized assessments.
Participants will be assigned to a study group based on their CRP level: CRP less than 1 (low
CRP), or CRP greater than or equal to 1 (high CRP). Within this group assignment,
participants will then be randomized, or assigned by chance (like flipping a coin), to one of
2 study groups:
• CRP consistent antidepressant selection (medication will be prescribed based on
participant's CRP level).
If CRP less than 1, participant will be prescribed escitalopram. If CRP greater than or equal
to 1, participant will be prescribed bupropion XL.
• CRP inconsistent antidepressant selection (medication will be prescribed in contradiction
to participant's CRP level) If CRP less than 1, participant will be prescribed bupropion XL.
If CRP greater than or equal to 1, participant will be prescribed escitalopram.
In each group participants will receive either escitalopram or bupropion XL.
- 1 tablet of 150 mg of bupropion-XL per day (initial dose). The dose will be increased to
300mg per day after the first week, and may be increased up to 450 mg/per day if deemed
necessary by the clinician.
- 1 tablet of 5 mg of escitalopram per day (initial dose). The dose will be increased to
10 mg per day after the first week, followed by an additional increase to 20 mg/day if
deemed necessary by clinician.
Participants and study doctors will know which medication is being used, but not which group
the participant is in; that is, participants and study doctors will not know the
participant's CRP levels nor whether the medication assignment is consistent with CRP levels.
The dose of the medication may be adjusted up or down during the study to improve effects of
the medication or reduce possible side effects. Dose changes will be made based on how the
participant is feeling and any side effects.
Participants will then complete a clinical visit at Week 2, 4, and 6. These visits will last
approximately 1 hour and 15 minutes, and will include the following:
- Clinical Evaluation: a psychiatrist will check the participant's vital signs and assess
their overall wellbeing. Symptom changes, side effects, and adherence to treatment will
be evaluated. Medication dosage adjustments will be made as necessary.
- Self-Report Questionnaires
The final clinical visit will occur at week 8. This visit will be the last in person visit
and will last approximately 1 hour and 45 minutes. The following will be completed
- Clinical Evaluation
- Self-Report Questionnaires
- Cognitive tests
- Bloodwork
- Pregnancy test (if you are a female able to become pregnant)
After study completion, participants who wish to remain on treatment will be given a four
week supply of study drug while they transition care.
Additionally, a remote follow up assessment will be done at Week 12. Participants will be
contacted via phone to complete a series of questionnaires. Additionally, they will receive a
series of self reports via email. Paper forms will be also available at the Center for
Depression Research and Clinical Care if the participant prefers to answer them on paper or
don't have access to an email.
The self-report questionnaires, study evaluations, and assessment of CRP levels and
additional inflammatory substances in this study are designed for research, not for medical
purposes. Even though the researchers are not specifically looking at blood to find a medical
problem, participants will be notified if any abnormal results are identified.
Participants will also have the option to participate in a Finger Prick Blood CRP substudy
that will compare CRP results based on the blood source: venous blood obtained via
venipuncture and capillary blood obtained via finger prick. A few drops of capillary blood
will be collected via finger prick once during the study at week 0 (screening/baseline). We
will compare the finger prick results to the results obtained from venipuncture at the same
visit.
