Experimental

Placebo Comparator

Arm Label

Minocycline

Placebo

Celecoxib

Arm Description

The dose of minocycline would be 50mg per day on week 1, 50mg bid on week 2 and 100mg bid weeks 3-8. For tapering, the dose will be reduced to 50mg bid for a week, and then stopped.

The number and appearance of the pills would be identical to those in the minocycline arm.

This will be an open label trial for those with Hamilton Depression Rating Scale score ≥ 8 following the minocycline v. placebo trial or those not eligible for Phase 2. Dose of celecoxib will be 100 mg bid for the first week and 200mg bid for weeks 2-8. For tapering, the dose of celecoxib will be reduced to 100mg bid for one week, and then stopped.

Outcomes

Primary Outcome Measures

Translocator total distribution volume (TSPO VT): Treatment Effect of Minocycline in MDE Subjects
TSPO VT will be measured using [18F]FEPPA positron emission tomography brain scans. Eligible MDE participants will be randomized to either minocycline or placebo. Following 8 weeks of either minocycline or placebo treatment, MDE participants will have a second PET scan .
Translocator total distribution volume (TSPO VT): Difference between MDE and healthy subjects
Compare baseline TSPO VT prior to treatment between MDE group and healthy group

Secondary Outcome Measures

Change in Hamilton Depression Rating Scale Score
Change in HDRS score following minocycline vs. placebo treatment. Change in HDRS score following celecoxib treatment.

5. Study Description

Brief Summary
The purpose of this study is to determine if translocator protein total distribution volume (TSPO VT) is elevated in major depressive disorder that is not responding to medication and if adding minocycline can affect TSPO VT. Many remain treatment resistant with common antidepressant treatments and the investigators think it may be due to poor targeting of brain pathologies.
Detailed Description
There will be three Phases in the study. Only MDE subjects will be invited to continue to Phase 2 and 3. Subjects will be invited to continue to the subsequent Phase given they meet entry criteria described below: Phase 1: The investigators will evaluate whether TSPO is elevated in individuals during a current MDE compared to healthy controls. Eligible participants will receive one [18F]FEPPA PET scan and one MRI scan. Other measures will include urine sample, blood samples for genetic and peripheral biomarker analysis, a neurocognitive battery, mood scales and questionnaires. Phase 2: Participants who have elevated TSPO VT in Phase 1 and are agreeable to receiving minocycline will be invited to participate in Phase 2. Based on our previous results participants will be considered candidates for Phase 2 if TSPO VT ≥ 10.5 (HAB) or ≥8.5 (MAB) in any of the primary regions of interest (prefrontal cortex, anterior cingulate cortex or insula). Eligible participants will be invited to participate in a randomized, double blind, placebo controlled trial, to receive either minocycline or placebo. After the eight weeks of treatment, participants will receive one [18F]FEPPA PET scan. Other measures will include urine samples, blood samples, mood scales and questionnaires. Phase 3: If, after the initial eight week treatment period with either minocycline or placebo, any participant continues to have depressive symptoms (17-item Hamilton Depression Rating Scale score ≥ 8) they will be invited to participate in an eight week open label trial of celecoxib. Participants not eligible for Phase 2 may also be invited to participate in Phase 3 directly from Phase 1.

Title
Genetic sample
Description
The priority of the genetic sample is to analyze the alleles of polymorphism rs6971 which has an association with the affinity of most second generation TSPO ligands including [18F]FEPPA. The genetic sample will also be used to study sequences of genes that are believed to affect TSPO expression, inflammation, mood and conditions that may predispose to mood disorders.
Time Frame
Phase 1-single sample

Blood samples (serum and plasma)
Description
Analyses will include complete blood cell count (CBC), ESR, hepatic and renal function. Peripheral marker analyses will include proteins related to TSPO expression and inflammation. Plasma minocycline and celecoxib levels will be analyzed.
Time Frame
