Clinical summary

Indications and usage 1 INDICATIONS AND USAGE TRINTELLIX is indicated for the treatment of major depressive disorder (MDD) in adults. TRINTELLIX is indicated for the treatment of major depressive disorder (MDD) in adults ( 1 , 14 ). Dosage and administration 2 DOSAGE AND ADMINISTRATION • The recommended starting dose is 10 mg administered orally once daily without regard to meals ( 2.1 ). • The dose should then be increased to 20 mg/day, as tolerated ( 2.1 ). • Consider 5 mg/day for patients who do not tolerate higher doses ( 2.1 ). • TRINTELLIX can be discontinued abruptly. However, it is recommended that doses of 15 mg/day or 20 mg/day be reduced to 10 mg/day for one week prior to full discontinuation if possible ( 2.3 ). • The maximum recommended dose is 10 mg/day in known CYP2D6 poor metabolizers ( 2.5 ). 2.1 Recommended Dosage The recommended starting dose is 10 mg administered orally once daily without regard to meals. Dosage should then be increased to 20 mg/day, as tolerated. The efficacy and safety of doses above 20 mg/day have not been evaluated in controlled clinical trials. A dose decrease down to 5 mg/day may be considered for patients who do not tolerate higher doses [see Clinical Studies (14) ] . 2.2 Screen for Bipolar Disorder Prior to Starting TRINTELLIX Prior to initiating treatment with TRINTELLIX or another antidepressant, screen patients for personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.4) ] . 2.3 Discontinuing Treatment Although TRINTELLIX can be abruptly discontinued, in placebo-controlled trials patients experienced transient adverse reactions such as headache and muscle tension following abrupt discontinuation of TRINTELLIX 15 mg/day or 20 mg/day. It is recommended that the dose be decreased to 10 mg/day for one week before full discontinuation of TRINTELLIX 15 mg/day or 20 mg/day [see Warnings and Precautions (5.5) and Adverse Reactions (6) ] . 2.4 Switching a Patient to or From a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders At least 14 days must elapse between discontinuation of a MAOI intended to treat psychiatric disorders and initiation of therapy with TRINTELLIX to avoid the risk of Serotonin Syndrome [see Warnings and Precautions (5.2) ] . Conversely, at least 21 days must elapse after stopping TRINTELLIX before starting an MAOI intended to treat psychiatric disorders [see Contraindications (4) ] . 2.5 Use of TRINTELLIX in Known CYP2D6 Poor Metabolizers or in Patients Taking Strong CYP2D6 Inhibitors The maximum recommended dose of TRINTELLIX is 10 mg/day in known CYP2D6 poor metabolizers. Reduce the dose of TRINTELLIX by one-half when patients are receiving a CYP2D6 strong inhibitor (e.g., bupropion, fluoxetine, paroxetine, or quinidine) concomitantly. The dose should be increased to the original level when the CYP2D6 inhibitor is discontinued [see Drug Interactions (7.1) , Use in Specific Populations (8.6) ] . 2.6 Use of TRINTELLIX in Patients Taking Strong CYP Inducers Consider increasing the dose of TRINTELLIX when a strong CYP inducer (e.g., rifampin, carbamazepine, or phenytoin) is coadministered for greater than 14 days. The maximum recommended dose should not exceed three times the original dose. The dose of TRINTELLIX should be reduced to the original level within 14 days, when the inducer is discontinued [see Drug Interactions (7.1) ] . Warnings and cautions 5 WARNINGS AND PRECAUTIONS • Serotonin Syndrome : Increased risk when coadministered with other serotonergic agents, but also when taken alone. If it occurs, discontinue TRINTELLIX and serotonergic agents and initiate supportive measures ( 5.2 ). • Increased Risk of Bleeding : Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs, other antiplatelet drugs, warfarin, or other drugs that affect coagulation may increase risk ( 5.3 ). • Activation of Mania/Hypomania : Screen patients for bipolar disorder ( 5.4 ). • Angle Closure Glaucoma: Angle closure glaucoma has occurred in patients with untreated anatomically narrow angles treated with antidepressants ( 5.6 ). • Hyponatremia : Can occur in association with the syndrome of inappropriate antidiuretic hormone secretion (SIADH) ( 5.7 ). • Sexual Dysfunction: TRINTELLIX may cause symptoms of sexual dysfunction ( 5.8 ). 5.1 Suicidal Thoughts and Behaviors in Adolescents and Young Adults In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied. There were differences in absolute risk of suicidal thoughts and behaviors
