- Brief Summary
The overall goal of the study is to determine if treatment of a Major Depressive Disorder (MDD) improves the outcomes of patients with chronic kidney disease (CKD). We showed that MDD is present in 25% of CKD patients and independently associated with progression to End-Stage Kidney Disease, hospitalization, and death. Depression is also associated with lower quality of life (QOL), fatigue, poor sleep, and non-adherence to diet and medications. However, evidence for efficacy and tolerability of commonly-used antidepressant medications or nonpharmacologic treatments are limited in CKD patients. Our group was the first to conduct a double-blind randomized controlled trial for MDD treatment in 201 patients with non-dialysis CKD, and showed that sertraline, a commonly used selective serotonin reuptake inhibitor (SSRI), was no more efficacious than placebo for improving depressive symptoms. It becomes imperative to test novel strategies to treat MDD in CKD. We propose to compare with a control group, the efficacy and tolerability of two novel treatment strategies - (1) Behavioral Activation Teletherapy (BAT) for 16 weeks, with the addition of bupropion, a non-SSRI antidepressant, at 8 weeks for patients whose depression has not remitted (non-remitters); and (2) bupropion for 16 weeks, with the addition of BAT at 8 weeks for non-remitters. In Aim 1, we will investigate the efficacy and tolerability of these 2 strategies vs. control for improvement in a primary endpoint of depressive symptoms in 201 patients (67 per group) with non-dialysis CKD stages 3b-5 and MDD at 2 sites, randomized 1:1:1 to either strategy or a control group of Clinical Management plus placebo. We hypothesize that either approach vs. control will result in a minimal clinically important difference of 2 points improvement in depressive symptoms, as ascertained blindly by the Quick Inventory of Depressive Symptomatology. In Aim 2 we will investigate the efficacy and tolerability of 8 weeks of (1) single-blind BAT plus placebo or (2) double-blind bupropion plus Clinical Management vs. control for improvement in depressive symptoms. In Aim 3, we will compare the efficacy of these 2 treatments strategies vs. control for improvement in CKD patient-centered outcomes including a. adherence to medications and healthcare visits; b. fatigue; c. sleep; and d. overall functioning. A clinical trial is urgently needed to address the evidence gap that exists for MDD treatment in CKD patients.
- Detailed Description
Aim 1. Compare the efficacy and tolerability of two 16-week strategies vs. control for treatment of CKD patients with MDD starting with (1) BAT or (2) bupropion, each augmented to a combination of both in non-remitters. Primary hypothesis: Treatment with either strategy will improve depression (primary endpoint) and be tolerable.
Patients with non-dialysis stages 3b-5 CKD and MDD (N=201) will be randomized 1:1:1 to 16 weeks of:
Strategy 1: Single-blind BAT plus placebo, augmented in non-remitters at 8 weeks with single-blind bupropion; Strategy 2: Double-blind bupropion plus single-blind Clinical Management (CM) attention control, augmented in non-remitters at 8 weeks with single-blind BAT; Control: CM attention control plus placebo. There will be \>80% power to detect a minimal clinically important difference (MCID) of 2 points on the Quick Inventory of Depressive Symptomatology between each intervention and control, assuming a 14% attrition rate.
Exploratory aim (a): Explore if remote access to therapy via internet vs. travel to clinic affects treatment efficacy.
Aim 2. Investigate efficacy and tolerability of 8 weeks (Phase 1) of (1) BAT plus placebo or (2) bupropion plus CM, vs. control, for improvement in depression. Secondary hypothesis: Treatment with 8 weeks of BAT or bupropion will improve depression. There will be 80% power to detect a MCID of 2 points between each arm and control, assuming 10% attrition.
Exploratory aims:
(a) Investigate whether patient preference for BAT vs. drug affects treatment efficacy; (b) compare efficacy of each combination in Phase 2 with control; (c) compare change from baseline in plasma C-reactive protein in drug vs. BAT or control arms.
Aim 3. Investigate the efficacy of these two 16-week treatment strategies vs. control for improvement in CKD patient-centered outcomes including: (a) adherence to medications and healthcare visits; (b) fatigue; (c) sleep; (d) overall functioning. Secondary hypothesis: Treatment with either strategy will result in clinically meaningful improvements in adherence, fatigue, sleep and overall functioning in patients with CKD.

- Primary Outcome Measures
Name Time Method Quick Inventory of Depressive Symptomatology-Clinician Rated scale (QIDS-C) Assessed at baseline and weeks 4, 6, 8, 12, and 16 Assess the change from baseline in the QIDS-C total score in each of the intervention arms vs. the control arm. The score on the QIDS-C ranges from 0-27, with higher scores indicating more severe depressive symptoms.
- Secondary Outcome Measures
Name Time Method Serious adverse events Assessed at weeks 4, 6, 8, 12, and 16. Pre-specified serious adverse events include death, hospitalization, renal replacement therapy (dialysis or kidney transplantation), and acute suicidal intent.
Serious adverse events with monotherapy Assessed at weeks 4, 6, and 8. Pre-specified serious adverse events include death, hospitalization, renal replacement therapy (dialysis or kidney transplantation), and acute suicidal intent during the first 8 weeks of the study.
High sensitivity C-reactive protein Assessed at baseline and week 8 Change from baseline to Week 8 in the plasma level of high sensitivity C-reactive protein (hsCRP) in the intervention groups vs. control.
Sleep assessed by the Insomnia Severity Index (ISI) Assessed at baseline and weeks 4, 8, 12, and 16 Change from baseline in the Insomnia Severity Index (ISI) in the intervention groups vs. control. The ISI has 7 items that measure insomnia severity, with higher scores indicating more severe insomnia.
Quick Inventory of Depressive Symptomatology-Clinician Rated scale (QIDS-C) Assessed at weeks 8, 12, and 16. Assess the change from baseline in the QIDS-C total score in each of the intervention arms vs. the control arm during the second 8 weeks of the study when participants who did not respond to the treatment arms will be receiving combination therapy with BAT and bupropion.
Adherence to medications by Pill Count Assessed at weeks 4, 8, 12, and 16. The proportion of participants in each arm that are adherent to antidepressant medications (or placebo, prescribed in the setting of the clinical trial). Adherence will be defined as 80% or greater of study drug taken.
Fatigue assessed by the Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F) scale Assessed at baseline and weeks 4, 8, 12, and 16 Change from baseline in the FACIT-F scale in the intervention groups vs. control. The FACIT has 13 items, each on a Likert scale, with a score range of 0-52, and higher scores indicating a lower level of fatigue.
Overall functioning assessed by the Sheehan Disability Scale (SDS) Assessed at baseline and weeks 4, 8, 12, and 16 Change from baseline in the SDS in the intervention groups vs. control groups. The SDS assesses functional impairment in 3 domains: work, social life, and family, each evaluated on a 10-point visual analog scale, which are summed into a single dimensional measure of global functional impairment that ranges from 0 (unimpaired) to 30 (highly impaired).
