Savella

1 INDICATIONS AND USAGE SAVELLA is indicated for the management of fibromyalgia. SAVELLA is not approved for use in pediatric patients [see Use in Specific Populations ( 8.4 )] . • SAVELLA ® is a selective serotonin and norepinephrine reuptake inhibitor (SNRI) indicated for the management of fibromyalgia ( 1 ). • SAVELLA is not approved for use in pediatric patients ( 1 ).

2 DOSAGE AND ADMINISTRATION SAVELLA is given orally with or without food. Taking SAVELLA with food may improve the tolerability of the drug. • Administer SAVELLA in two divided doses per day ( 2.1 ). • Based on efficacy and tolerability, dosing may be titrated according to the following schedule ( 2.1 ): Day 1: 12.5 mg once Days 2-3: 25 mg/day (12.5 mg twice daily) Days 4-7: 50 mg/day (25 mg twice daily) After Day 7: 100 mg/day (50 mg twice daily) • Recommended dose is 100 mg/day ( 2.1 ). • May be increased to 200 mg/day based on individual patient response ( 2.1 ). • Adjust dose in patients with severe renal impairment ( 2.2 ). 2.1 Recommended Dosing The recommended dose of SAVELLA is 100 mg/day (50 mg twice daily). Based on efficacy and tolerability dosing may be titrated according to the following schedule: Day 1: 12.5 mg once Days 2-3: 25 mg/day (12.5 mg twice daily) Days 4-7: 50 mg/day (25 mg twice daily) After Day 7: 100 mg/day (50 mg twice daily) Based on individual patient response, the dose may be increased to 200 mg/day (100 mg twice daily). Doses above 200 mg/day have not been studied. Taper SAVELLA and do not abruptly discontinue after extended use [see Dosage and Administration ( 2.4 ), Warnings and Precautions ( 5.7 )] . 2.2 Patients with Renal Insufficiency No dosage adjustment is necessary in patients with mild renal impairment. Use SAVELLA with caution in patients with moderate renal impairment. For patients with severe renal impairment (indicated by an estimated creatinine clearance of 5-29 mL/min), reduce the maintenance dose by 50% to 50 mg/day (25 mg twice daily). Based on individual patient response, the dose may be increased to 100 mg/day (50 mg twice daily). SAVELLA is not recommended for patients with end-stage renal disease. 2.3 Patients with Hepatic Insufficiency No dosage adjustment is necessary for patients with hepatic impairment. As with any drug, exercise caution in patients with severe hepatic impairment. 2.4 Discontinuing SAVELLA Withdrawal symptoms have been observed in clinical trials following discontinuation of milnacipran, as with other serotonin and norepinephrine re-uptake inhibitors (SNRIs) and selective serotonin re-uptake inhibitors (SSRIs). Monitor patients for these symptoms when discontinuing treatment. Taper SAVELLA and do not abruptly discontinue after extended use [see Warnings and Precautions ( 5.7 )] . 2.5 Switching a Patient to or from a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders At least 14 days should elapse between discontinuation of a MAOI intended to treat psychiatric disorders and initiation of therapy with SAVELLA. Conversely, allow at least 5 days after stopping SAVELLA before starting a MAOI intended to treat psychiatric disorders [see Contraindications ( 4.1 )] . 2.6 Use of SAVELLA with other MAOIs such as Linezolid or Methylene Blue Do not start SAVELLA in a patient being treated with linezolid or intravenous methylene blue because there is increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, consider other interventions, including hospitalization [see Contraindications ( 4.1 )] . In some cases, a patient already receiving SAVELLA therapy may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue treatment are judged to outweigh the risks of serotonin syndrome in a particular patient, discontinue SAVELLA promptly, and consider administering linezolid or intravenous methylene blue. Monitor the patient for symptoms of serotonin syndrome for 5 days or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with SAVELLA may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see Warnings and Precautions ( 5.2 )]…

5 WARNINGS AND PRECAUTIONS • Suicidality : Monitor for worsening of depressive symptoms and suicide risk ( 5.1 ). • Serotonin Syndrome : Increased risk when co-administered with other serotonergic agents, but also when taken alone. If it occurs, discontinue SAVELLA and any other serotonergic agents, and initiate supportive treatment ( 5.2 ). • Elevated Blood Pressure and Heart Rate : SAVELLA may increase blood pressure and heart rate. Measure blood pressure and heart rate prior to initiating treatment with SAVELLA and monitor periodically throughout treatment ( 5.3 , 5.4 ). • Seizures : Cases have been reported with SAVELLA therapy. Prescribe SAVELLA with care in patients with a history of seizure disorder ( 5.5 ). • Hepatotoxicity : SAVELLA may cause elevations of ALT and AST. Avoid concomitant use of SAVELLA in patients with substantial alcohol use or chronic liver disease ( 5.6 ). • Discontinuation : Withdrawal symptoms have been reported in patients when discontinuing treatment with SAVELLA. A gradual dose reduction is recommended ( 5.7 ). • Increased Risk of Bleeding : SAVELLA may increase the risk of bleeding events. Caution patients about the risk of bleeding associated with the concomitant use of SAVELLA and NSAIDs, aspirin, or other drugs that affect coagulation ( 5.9 ). • History of Dysuria : Male patients with a history of obstructive uropathies may experience higher rates of genitourinary adverse events ( 5.11 ). • Sexual Dysfunction : SAVELLA use may cause symptoms of sexual dysfunction ( 5.12 ). 5.1 Suicide Risk SAVELLA is a selective serotonin and norepinephrine re-uptake inhibitor (SNRI), similar to some drugs used for the treatment of depression and other psychiatric disorders. Patients, both adult and pediatric, with depression or other psychiatric disorders may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking these medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants, including drugs that inhibit the reuptake of norepinephrine and/or serotonin, may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. In the placebo-controlled clinical trials of adults with fibromyalgia, among the patients who had a history of depression at treatment initiation, the incidence of suicidal ideation was 0.5% in patients treated with placebo, 0% in patients treated with SAVELLA 100 mg/day, and 1.3% in patients treated with SAVELLA 200 mg/day. No suicides occurred in the short-term or longer-term (up to 1 year) fibromyalgia trials. Pooled analyses of short-term placebo-controlled trials of drugs used to treat depression (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18-24) with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with these drugs compared to placebo in adults beyond age 24; there was a reduction in suicidality risk with antidepressants compared to placebo in adults age 65 and older. The pooled analyses of placebo-controlled trials in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short-term trials of 9 drugs used to treat depression in over 4400 patients. The pooled analyses of placebo-controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short-term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients. There was considerable varia…

4 CONTRAINDICATIONS • Serotonin Syndrome and MAOIs: Do not use MAOIs intended to treat psychiatric disorders with SAVELLA or within 5 days of stopping treatment with SAVELLA. Do not use SAVELLA within 14 days of stopping an MAOI intended to treat psychiatric disorders. In addition, do not start SAVELLA in a patient who is being treated with linezolid or intravenous methylene blue ( 4.1 , 5.2 ). 4.1 Monoamine Oxidase Inhibitors (MAOIs) The use of MAOIs intended to treat psychiatric disorders with SAVELLA or within 5 days of stopping treatment with SAVELLA is contraindicated because of an increased risk of serotonin syndrome. The use of SAVELLA within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated [see Dosage and Administration ( 2.5 ), Warnings and Precautions ( 5.2 )] . Starting SAVELLA in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome [see Dosage and Administration ( 2.6 ), Warnings and Precautions ( 5.2 )] .

7 DRUG INTERACTIONS Milnacipran undergoes minimal CYP450 related metabolism, with the majority of the dose excreted unchanged in urine (55%) and has a low binding to plasma proteins (13%). In vitro and in vivo studies showed that SAVELLA is unlikely to be involved in clinically significant pharmacokinetic drug interactions [see Pharmacokinetics in Special Populations ( 12.3 )] . • SAVELLA is unlikely to be involved in clinically significant pharmacokinetic drug interactions ( 7 ). • Pharmacodynamic interactions of SAVELLA with other drugs can occur ( 7 ). 7.1 Monoamine Oxidase Inhibitors (MAOIs) The concomitant use of SSRIs and SNRIs, including SAVELLA, with MAOIs increases the risk of serotonin syndrome. The use of MAOIs intended to treat psychiatric disorders with SAVELLA or within 5 days of stopping treatment with SAVELLA is contraindicated. The use of SAVELLA within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated. In addition, do not initiate SAVELLA in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). If it is necessary to initiate treatment with a MAOI such as linezolid or intravenous methylene blue in a patient taking SAVELLA, discontinue SAVELLA before initiating treatment with the MAOI [see Dosage and Administration ( 2.5 , 2.6 ), Contraindications ( 4 ), Drug Interactions ( 7.1 )] . 7.2 Serotonergic Drugs Serotonin syndrome can occur with use of SAVELLA and other serotonergic drugs (other SNRIs, SSRIs, triptans, tricyclic antidepressants, opioids, lithium, tryptophan, buspirone, amphetamines, and St. John’s Wort), or with drugs that impair metabolism of serotonin (i.e., monoamine oxidase inhibitors). Advise patients of the signs and symptoms associated with serotonin syndrome and to seek medical care immediately if they experience these symptoms [see Dosage and Administration ( 2.5 , 2.6 ), Warnings and Precautions ( 5.2 )] . 7.3 Triptans There have been rare postmarketing reports of serotonin syndrome with use of an SSRI and a triptan. If concomitant treatment of SAVELLA with a triptan is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases [see Warnings and Precautions ( 5.2 )] . 7.4 Catecholamines SAVELLA inhibits the reuptake of norepinephrine. Therefore, concomitant use of SAVELLA with epinephrine and norepinephrine may be associated with paroxysmal hypertension and possible arrhythmia [see Warnings and Precautions ( 5.3 , 5.4 )] . 7.5 CNS-active drugs Given the primary CNS effects of SAVELLA, use caution when it is taken in combination with other centrally acting drugs, including those with a similar mechanism of action. Clomipramine: In a drug-drug interaction study, an increase in euphoria and postural hypotension was observed in patients who switched from clomipramine to SAVELLA. 7.6 Clinically Important Interactions with Select Cardiovascular Agents Digoxin: Use of SAVELLA concomitantly with digoxin may be associated with potentiation of adverse hemodynamic effects. Postural hypotension and tachycardia have been reported in combination therapy with intravenously administered digoxin (1 mg). Avoid co-administration of SAVELLA and intravenous digoxin [see Warnings and Precautions ( 5.3 , 5.4 )] . Clonidine: Because SAVELLA inhibits norepinephrine reuptake, co-administration with clonidine may inhibit clonidine’s anti-hypertensive effect. 7.7 Drugs that Interfere with Hemostasis Concomitant use of SAVELLA with an antiplatelet or anticoagulant drug (e.g., NSAIDs, aspirin, and warfarin) may potentiate the risk of bleeding. This may be due to the effect of SAVELLA on the release of serotonin by platelets. Closely monitor for bleeding for patients receiving an antiplatelet or anticoagulant drug when SAVELLA is initiated or discontinued…

8.1 Pregnancy Risk Summary Based on data from published observational studies, exposure to SNRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage [see Warnings and Precautions ( 5.2 )] . The available data on SAVELLA use in pregnant women are insufficient to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. There are risks associated with exposure to serotonin and norepinephrine reuptake inhibitors (SNRIs) and selective-serotonin reuptake inhibitors (SSRIs), including SAVELLA, during pregnancy (see Clinical Considerations). Animal reproduction studies have been performed in rats, rabbits and mice. Milnacipran was shown to increase embryofetal and perinatal lethality in rats and the incidence of a minor skeletal variation in rabbits at doses below (rat) or approximately equal to (rabbit) the maximum recommended human dose (MRHD) of 200 mg/day on a mg/m 2 basis. No effects were seen in mice when treated with milnacipran during the period of organogenesis at doses up to 3 times the MHRD on a mg/m 2 basis (see Data). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%-4% and 15%-20%, respectively. Clinical Consideration Maternal adverse reactions Use of SAVELLA in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see Warnings and Precautions ( 5.9 )]. Fetal/Neonatal adverse reactions Neonates exposed to SNRIs or SSRIs, including SAVELLA, late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. These findings are consistent with either direct toxic effect of SSRIs and SNRIs or possibly, a drug discontinuation syndrome. It should be noted that, in some cases, the clinical picture is consistent with serotonin syndrome [see Warnings and Precautions ( 5.2 , 5.7 )]. Data Animal Data Studies were conducted in rats, rabbits and mice with dosing of milnacipran during the period of organogenesis. In rats, milnacipran was shown to increase embryofetal lethality at doses of 5 mg/kg/day (0.25 times the MRHD on a mg/m 2 basis). In rabbits, dose-dependent increases in the incidence of the skeletal variation of an extra single rib were observed in several pups from multiple litters in the absence of maternal toxicity at 15 mg/kg/day (1.5 times the MRHD on a mg/m 2 basis). The clinical significance of this finding is unknown. In mice, no embryotoxic or teratogenic effects were seen at doses up to 125 mg/kg/day (3 times the MHRD on a mg/m 2 basis). With peri- and postnatal exposure to oral milnacipran in rats, decreases in viability and body weight were observed on Postpartum Day 4 at a dose of 5 mg/kg/day (approximately 0.25 times the MRHD on a mg/m 2 basis). The no-effect dose for maternal and offspring toxicity was 2.5 mg/kg/day (approximately 0.1 times the MRHD on a mg/m 2 basis).

6 ADVERSE REACTIONS The most frequently occurring adverse reactions (≥ 5% and greater than placebo) were nausea, headache, constipation, dizziness, insomnia, hot flush, hyperhidrosis, vomiting, palpitations, heart rate increased, dry mouth, and hypertension ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact AbbVie at 1-800-678-1605 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Patient Exposure SAVELLA was evaluated in three double-blind placebo-controlled trials involving 2209 fibromyalgia patients (1557 patients treated with SAVELLA and 652 patients treated with placebo) for a treatment period up to 29 weeks. The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse reaction of the type listed. A reaction was considered treatment emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. Adverse Reactions Leading to Discontinuation In placebo-controlled trials in patients with fibromyalgia, 23% of patients treated with SAVELLA 100 mg/day, 26% of patients treated with SAVELLA 200 mg/day discontinued prematurely due to adverse reactions, compared to 12% of patients treated with placebo. The adverse reactions that led to withdrawal in ≥ 1% of patients in the SAVELLA treatment group and with an incidence rate greater than that in the placebo treatment group were nausea (milnacipran 6%, placebo 1%), palpitations (milnacipran 3%, placebo 1%), headache (milnacipran 2%, placebo 0%), constipation (milnacipran 1%, placebo 0%), heart rate increased (milnacipran 1%, placebo 0%), hyperhidrosis (milnacipran 1%, placebo 0%), vomiting (milnacipran 1%, placebo 0%), and dizziness (milnacipran 1% and placebo 0.5%). Discontinuation due to adverse reactions was generally more common among patients treated with SAVELLA 200 mg/day compared to SAVELLA 100 mg/day. Most Common Adverse Reactions in Placebo Controlled Trials In the placebo-controlled fibromyalgia patient trials, the most frequently occurring adverse reaction in clinical trials was nausea. The most common adverse reactions (incidence ≥ 5% and twice placebo) in patients treated with SAVELLA were constipation, hot flush, hyperhidrosis, vomiting, palpitations, heart rate increased, dry mouth, and hypertension. Table 4 lists all adverse reactions that occurred in at least 2% of patients treated with SAVELLA at either 100 or 200 mg/day and at an incidence greater than that of placebo.
