During the 18-day blind treatment period, subjects will be prescribed methylphenidate 5-10 mg twice per day and selective serotonin reuptake inhibitor (SSRI). Subjects already receiving a SSRI when they begin the study, will continue on the recommended dose of that SSRI; subjects not receiving a SSRI will be prescribed 10-20 mg per day Citalopram. Subjects who respond to methylphenidate treatment will have the option of continuing on methylphenidate, up to 15 mg bid, and an antidepressant in the 6 week open label portion of the study.

During the 18-day blind treatment period, subjects will be prescribed placebo 1-2 capsules twice per day and selective serotonin reuptake inhibitor (SSRI). Subjects already receiving a SSRI when they begin the study, will continue on the recommended dose of that SSRI; subjects not receiving a SSRI will be prescribed 10-20 mg per day Citalopram.

Subjects will take methylphenidate 5 mg twice daily (bid) for 3 days, then 10 mg bid for the remainder of the study. Should a subject have a 50% decrease in their depressive symptoms as measured by the Montgomery Asberg Depression Rating Scale (MADRS) at the initial dose of methylphenidate, they will be maintained at that lower dose as long as their MADRS score remains reduced by 50%. During the 18-day blinded treatment period the total daily dose will not exceed 20 mg.

If subjects have side effects when increasing to 10 mg bid, they will drop back to 5 mg bid. If the participant develops psychosis or cardiac events, they will be discontinued from methylphenidate.

Subjects who receive methylphenidate and respond with a 50% reduction in MADRS score will have the option to continue in the open label portion of the study for up to 6 weeks. For patients taking methylphenidate 10 mg bid whose MADRS score is \> 10 at day 18, the dose may be increased to 15 mg bid.

Subjects assigned to placebo will receive 1 capsule of placebo twice per day (bid) for 3 days and then 2 capsules bid for the remainder of the study. Should a subject have a 50% decrease in their depressive symptoms as measured by the Montgomery Asberg Depression Rating Scale (MADRS) at the initial dose of placebo, they will be maintained at that lower dose as long as their MADRS score remains reduced by 50%.

If subjects have side effects when increasing the dose to 2 capsules bid, they will drop back to 1 capsule bid. If the participant develops psychosis or cardiac events, they will be discontinued from the intervention.

Placebo

Each subject will be treated with a SSRI. Patients who are taking an SSRI at the time of enrollment will continue on the same medication during the 18-day blind treatment period. The prescribed dose will only be adjusted if it is more than the highest dose in the recommended range (fluoxetine to 40 mg, paroxetine to 40 mg, citalopram to 40 mg, sertraline to 150 mg). Patients who are not on a SSRI at the time of enrollment will be prescribed citalopram 10 mg per day for 2 weeks, then 20 mg per day.

A subject's SSRI may be discontinued if the subject experiences moderate to severe side effects likely attributable to a SSRI. If subjects experience similar symptoms when increasing their citalopram dose to 20 mg per day, they will drop back to 10 mg per day. During the open label extension, the SSRI may be increased, decreased, or changed to a different SSRI or other antidepressant with the exception of venlafaxine and bupropion

Selective Serotonin Uptake Inhibitor (SSRI)

Linda K. Ganzini, MD MPH

The purpose of this study is to determine whether methylphenidate is an effective treatment for depression and to document the safety and tolerability of methylphenidate in combination with an Selective Serotonin Reuptake Inhibitor (SSRI) in SSRI treated, terminally ill, hospice and palliative care cancer patients. The investigators hypothesize that depressed hospice and palliative care patients will be more likely to have a 50% reduction in scores on a clinical measure of depression after treatment with Methylphenidate plus an SSRI compared to those patients who are taking a placebo plus an SSRI.

Background: Major depressive disorder can be diagnosed in between 5% and 26% of terminally ill patients. This disorder causes suffering, and is associated with suicidality, increased pain, and increased caregiver burden and caregiver depression. Treatment of depression in cancer patients in hospice and palliative care is complicated by shortened life expectancy. Currently-approved antidepressants take several weeks to be effective. Methylphenidate has been reported in case series and very small randomized trials in patients without cancer as a rapidly effective treatment for depression in medically ill patients. There are no randomized controlled trials to test this agent in terminally ill cancer patients.

Objectives: (1) To determine the effectiveness and safety of methylphenidate for depression treatment in cancer patients receiving hospice and palliative care, (2) to explore whether successful treatment of depression is associated with improved quality of life, and (3) to explore whether effective treatment of depression influences caregiver depression and caregiver burden.

Methods: We will conduct an 18-day randomized, double-blind, fixed-dose (10 mg bid), placebo-controlled clinical trial of methylphenidate for depression in eligible veteran and non-veteran cancer patients with advanced cancer in the following settings: inpatient and outpatient hospice, inpatient and outpatient palliative care, and inpatient and outpatient cancer clinics. We will determine whether improvement in depression is mediated by decreased pain and document the safety and tolerability of methylphenidate in these patients. We will explore whether improvement in depression results in improved quality of life for these patients, and decreases caregiver depression and burden.

Eligible patients who answer yes to the question "are you sad or depressed" will be invited to participate. They will complete measures of depression \[Structured Clinical Interview for Diagnosis (SCID), Montgomery-Asberg Depression Rating Scale (MADRS) as primary outcome, Hospital Anxiety and Depression Scale (HADS) as secondary outcome\], quality of life, pain, and cognition at baseline. MADRS scores must be greater than 19 and SCID positive for depression at study entry. Subjects will be randomized to either methylphenidate plus an SSRI, or placebo plus an SSRI. Subjects may continue any previously prescribed SSRI, or will be prescribed citalopram if untreated. Participants will be evaluated with the same measures as baseline on days 3, 6, 12 and 18 of the study. In an open label portion of the study, methylphenidate-treated patients whose depression has improved will be followed up to 2 months. Cox proportional hazard analysis will be used to analyze the primary outcome. An estimated 104 subjects will be entered over five years. Caregivers will complete measures of depression and caregiver burden at days 0 and 18.

During the 18-day blind treatment period, subjects will be prescribed Methylphenidate 5-10 mg twice per day and Selective Serotonin Reuptake Inhibitor. Subjects receiving a SSRI when they begin the study, will continue on the recommended dose of that SSRI; subjects not already receiving a SSRI will be prescribed 10-20 mg per day Citalopram. Subjects who respond to methylphenidate treatment will have the option of continuing on methylphenidate, up to 15 mg bid, and an antidepressant in the 6 week open label portion of the study.

Methylphenidate + SSRI

During the 18-day blind treatment period, subjects will be prescribed placebo 1-2 capsules twice per day and Selective Serotonin Reuptake Inhibitor. Subjects receiving a SSRI when they begin the study, will continue on the recommended dose of that SSRI; subjects not already receiving a SSRI will be prescribed 10-20 mg per day Citalopram.
