Sequenced Treatment Alternatives to Relieve Depression (STAR*D) was a collaborative study on the treatment of depression, funded by the National Institute of Mental Health. Its main focus was on the treatment of depression in patients where the first prescribed antidepressant proved inadequate. A key feature of the study was its aim to be more generalizable to real clinical situations; this was done through the use of minimal exclusion criteria, incorporating patient preference, and not blinding the treatments (i.e. the patient and clinician both knew what treatment the patient was receiving). [1] The STAR*D trial included remission (the near-absence of symptoms, rather than simply a reduction in symptoms) as an outcome measure, as there is evidence that patients with depression who achieve remission function better and are less prone to relapse than those who achieve only partial improvement in symptoms [1]

Contents

Trial

The STAR*D trial enrolled 4,041 outpatients with nonpsychotic depression at 23 psychiatric and 18 primary care sites. [2] The trial was completed in 2006, and data from it has been available since 2008.

The trial involved four different treatment levels, and patients were encouraged to enter the next level of treatment if they failed to achieve remission or response (50% reduction in symptoms) after a specified number of weeks. [1]

In level one, patients received the selective serotonin reuptake inhibitor (SSRI) citalopram for up to 14 weeks, with adjustment of the dose being managed by their own physicians. [1] If patients achieved remission or response during that time period, they could enter a 12-month naturalistic follow-up, during which time the researchers did not have any influence over the treatment plan. [1] [3] Non-remitters were encouraged to enter level two.

In level two, there were seven different treatment options, and cognitive behavioral therapy (CBT) was included as the psychotherapy option. There were three combination options (either an antidepressant or CBT added to citalopram), and four switch options (to either a different antidepressant or CBT). [1] Those who remitted or responded were offered 12-month naturalistic follow-up; non-remitters after two medication trials were encouraged to enter level 3; other non-remitters entered level 2A, which involved a second antidepressant trial. [1]

In level three, patients were offered the addition of lithium or triiodothyronine (a thyroid hormone) to their antidepressant, or a switch to another antidepressant (mirtazapine or nortriptyline). [1] This continued for 12 weeks.

Level four consisted of the monoamine oxidase inhibitor tranylcypromine or a combination of venlafaxine and mirtazapine. [1]

Results

For level one, the remission rate was 28-33% (depending on the symptom scale used), and the response rate was 47%. [4] Higher remission rates were seen in patients who were Caucasian, female, employed, or had higher levels of income or education. [4] Lower remission rates were seen in those with longer depressive episodes, co-occurring anxiety or substance use disorders, and more physical illness. [4]

For level two, patients who received CBT, either alone or combined with citalopram, had similar response and remission rates compared to those who were receiving medication(s) only; however, for those patients who remained on citalopram, those who had another antidepressant added achieved remission more rapidly than those who had CBT added. [4] Among the patients who were switched to a different antidepressant, there was no significant difference among the different antidepressants.

For level three, the remission rates based on the HAM-D symptom scale were 12.3% for mirtazapine and 19.8% for nortriptyline, although the difference was not large enough for statistical significance. [4] The remission rates based on the HAM-D in the combination strategy were 15.9% for lithium and 24.7% for triiodothyronine, but the difference was not statistically significant. [4] However, more patients receiving lithium than triiodothyronine left the study due to side effects. [4]

For level four, the average remission rate was 13%, with no statistically significant difference between tranylcypromine and the venlafaxine/mirtazapine combination. [4] More patients receiving tranylcypromine left the study due to side effects. [4]

Overall, the study findings indicate that patients who do not achieve remission or response after several weeks of citalopram treatment could achieve those outcomes by the end of 14 weeks. [1] The STAR*D researchers state that their data "suggest that a patient with persistent depression can get well after trying several treatment strategies, but his or her odds of beating the depression diminish as additional treatment strategies are needed." [5] With failed treatment at a higher step, the chances of remission were smaller – and this decrease was particularly significant after level two. [1] For those who did achieve full remission, there was a decreased chance of relapse at 12-month (naturalistic) follow-up compared to those patients who only responded. [1]

Criticism

Criticism of bias has been raised by certain researchers about the STAR*D trial: [6]

A psychiatric or psychotropic medication is a psychoactive drug taken to exert an effect on the chemical makeup of the brain and nervous system. Thus, these medications are used to treat mental illnesses. These medications are typically made of synthetic chemical compounds and are usually prescribed in psychiatric settings, potentially involuntarily during commitment. Since the mid-20th century, such medications have been leading treatments for a broad range of mental disorders and have decreased the need for long-term hospitalization, thereby lowering the cost of mental health care. The recidivism or rehospitalization of the mentally ill is at a high rate in many countries, and the reasons for the relapses are under research.

<span class="mw-page-title-main">Sertraline</span> Antidepressant (SSRI class) medication

Sertraline, sold under the brand name Zoloft among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. The efficacy of sertraline for depression is similar to that of other antidepressants, and the differences are mostly confined to side effects. Sertraline is better tolerated than the older tricyclic antidepressants. Sertraline is effective for panic disorder, social anxiety disorder, generalized anxiety disorder (GAD), and obsessive–compulsive disorder (OCD). However, for OCD, cognitive behavioral therapy, particularly in combination with sertraline, is a better treatment. Although approved for post-traumatic stress disorder (PTSD), sertraline leads to only modest improvement in this condition. Sertraline also alleviates the symptoms of premenstrual dysphoric disorder (PMDD) and can be used in sub-therapeutic doses or intermittently for its treatment.

Escitalopram, sold under the brand names Lexapro and Cipralex, among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. Escitalopram is mainly used to treat major depressive disorder and generalized anxiety disorder. It is taken by mouth, available commercially as an oxalate salt exclusively.

<span class="mw-page-title-main">Citalopram</span> Antidepressant of the selective serotonin reuptake inhibitor (SSRI) class

Citalopram, sold under the brand name Celexa among others, is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It is used to treat major depressive disorder, obsessive compulsive disorder, panic disorder, and social phobia. The antidepressant effects may take one to four weeks to occur. It is typically taken orally. In some European countries, it is sometimes given intravenously to initiate treatment, before switching to the oral route of administration for continuation of treatment. It has also been used intravenously in other parts of the world in some other circumstances.

<span class="mw-page-title-main">Venlafaxine</span> Antidepressant medication

Venlafaxine, sold under the brand name Effexor among others, is an antidepressant medication of the serotonin-norepinephrine reuptake inhibitor (SNRI) class. It is used to treat major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. Studies have shown that Venlafaxine improves quality of life. It may also be used for chronic pain. It is taken by mouth. It is also available as the salt venlafaxine besylate in an extended-release formulation.

<span class="mw-page-title-main">Mirtazapine</span> Antidepressant medication

Mirtazapine, sold under the brand name Remeron amongst others, is an atypical tetracyclic antidepressant, and as such is used primarily to treat depression. Its effects may take up to four weeks, but can also manifest as early as one to two weeks. It is often used in cases of depression complicated by anxiety or insomnia. The effectiveness of mirtazapine is comparable to other commonly prescribed antidepressants. It is taken by mouth.

<span class="mw-page-title-main">Serotonin–norepinephrine reuptake inhibitor</span> Class of antidepressant medication

Serotonin–norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressant medications used to treat major depressive disorder (MDD), anxiety disorders, obsessive–compulsive disorder (OCD), social phobia, attention-deficit hyperactivity disorder (ADHD), chronic neuropathic pain, fibromyalgia syndrome (FMS), and menopausal symptoms. SNRIs are monoamine reuptake inhibitors; specifically, they inhibit the reuptake of serotonin and norepinephrine. These neurotransmitters are thought to play an important role in mood regulation. SNRIs can be contrasted with the selective serotonin reuptake inhibitors (SSRIs) and norepinephrine reuptake inhibitors (NRIs), which act upon single neurotransmitters.

<span class="mw-page-title-main">Generalized anxiety disorder</span> Long-lasting anxiety not focused on any one object or situation

Generalized anxiety disorder (GAD) is a mental and behavioral disorder, specifically an anxiety disorder characterized by excessive, uncontrollable and often irrational worry about events or activities. Worry often interferes with daily functioning, and individuals with GAD are often overly concerned about everyday matters such as health, finances, death, family, relationship concerns, or work difficulties. Symptoms may include excessive worry, restlessness, trouble sleeping, exhaustion, irritability, sweating, and trembling.

Double depression refers to the co-existence of major depressive disorder (MDD) and persistent depressive disorder (PDD),. Research has shown that double depression tends to be more severe than either MDD or PDD alone and that individuals with double depression experience relapse more often than those with either MDD or PDD alone. However, there is some research that indicates few differences exist between double depression, MDD, and PDD; as a result, those researchers conclude that double depression is not a distinct disorder.

Dysthymia, also known as persistent depressive disorder (PDD), is a mental and behavioral disorder, specifically a disorder primarily of mood, consisting of similar cognitive and physical problems as major depressive disorder, but with longer-lasting symptoms. The concept was used by Robert Spitzer as a replacement for the term "depressive personality" in the late 1970s.

Atypical depression is defined in the DSM IV as depression that shares many of the typical symptoms of major depressive disorder or dysthymia but is characterized by improved mood in response to positive events. In contrast to those with atypical depression, people with melancholic depression generally do not experience an improved mood in response to normally pleasurable events. Atypical depression also often features significant weight gain or an increased appetite, hypersomnia, a heavy sensation in the limbs, and interpersonal rejection sensitivity that results in significant social or occupational impairment.

<span class="mw-page-title-main">Psychotic depression</span> Medical condition

Psychotic depression, also known as depressive psychosis, is a major depressive episode that is accompanied by psychotic symptoms. It can occur in the context of bipolar disorder or major depressive disorder. It can be difficult to distinguish from schizoaffective disorder, a diagnosis that requires the presence of psychotic symptoms for at least two weeks without any mood symptoms present. Unipolar psychotic depression requires that psychotic symptoms occur during severe depressive episodes, although residual psychotic symptoms may also be present in between episodes. Diagnosis using the DSM-5 involves meeting the criteria for a major depressive episode, along with the criteria for "mood-congruent or mood-incongruent psychotic features" specifier.

The cognitive behavioral analysis system of psychotherapy (CBASP) is a talking therapy, a synthesis model of interpersonal and cognitive and behavioral therapies developed by James P. McCullough Jr. of Virginia Commonwealth University specifically for the treatment of all varieties of DSM-IV chronic depression. McCullough writes that chronic depression, particularly the type beginning during adolescence (early-onset), is essentially a refractory mood disorder arising from traumatic experiences or interpersonal psychological insults delivered by the patient's significant others.
