Encourage patients to enroll by calling 1-833-569-2635 or visiting www.vumeritypregnancyregistry.com. Risk Summary There are no adequate data on the developmental risk associated with the use of VUMERITY in pregnant women. Available data from a pregnancy registry for dimethyl fumarate (which has the same active metabolite as VUMERITY), observational studies, and pharmacovigilance pertaining to dimethyl fumarate use in pregnant women have not indicated an increased risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Most of the reported exposures to dimethyl fumarate occurred during the first trimester of pregnancy (see Data ). In animal studies, administration of diroximel fumarate during pregnancy or throughout pregnancy and lactation resulted in adverse effects on embryofetal and offspring development (increased incidences of skeletal abnormalities, increased mortality, decreased body weights, neurobehavioral impairment) at clinically relevant drug exposures [ see Data ]. The 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. Data Human Data In a prospective observational pregnancy registry for dimethyl fumarate (2013-2022), the rate of major birth defects among 362 live births and stillbirths from women who were exposed to dimethyl fumarate during pregnancy was 3.6% (95% CI: 1.9-6.1). No specific pattern of major birth defects was identified. Important potential study limitations include exposure misclassification, no adjustment for confounders, and lack of an internal comparator cohort. Animal Data Oral administration of diroximel fumarate (0, 40, 100, or 400 mg/kg/day) to pregnant rats throughout organogenesis resulted in a decrease in fetal body weight and an increase in fetal skeletal variations at the highest dose tested, which was associated with maternal toxicity. Plasma exposures (AUC) for MMF and HES (the major circulating drug-related compound in humans) at the no-effect dose (100 mg/kg/day) for adverse effects on embryofetal development were approximately 2 times those in humans at the recommended human dose (RHD) of 924 mg/day. Oral administration of diroximel fumarate (0, 50, 150, or 350 mg/kg/day) to pregnant rabbits throughout organogenesis resulted in an increase in fetal skeletal malformations at the mid and high doses and reduced fetal body weight and increases in embryofetal death and fetal skeletal variations at the highest dose tested. The high dose was associated with maternal toxicity. Plasma exposures (AUC) for MMF and HES at the no-effect dose (50 mg/kg/day) for adverse effects on embryofetal development were similar to (MMF) or less than (HES) those in humans at the RHD. Oral administration of diroximel fumarate (0, 40, 100, or 400 mg/kg/day) to rats throughout gestation and lactation resulted in reduced weight, which persisted into adulthood, and adverse effects on neurobehavioral function in offspring at the highest dose tested. Plasma exposures (AUC) for MMF and HES at the no-effect dose for adverse effects on postnatal development (100 mg/kg/day) were approximately 3 times (MMF) or similar to (HES) those in humans at the RHD."],"description":["11 DESCRIPTION VUMERITY contains diroximel fumarate.

The clinical studies described below were conducted using dimethyl fumarate. The efficacy and safety of dimethyl fumarate were demonstrated in two studies (Studies 1 and 2) that evaluated dimethyl fumarate taken either twice or three times a day in patients with relapsing-remitting multiple sclerosis (RRMS). The starting dose for dimethyl fumarate was 120 mg twice or three times a day for the first 7 days, followed by an increase to 240 mg twice or three times a day. Both studies included patients who had experienced at least 1 relapse over the year preceding the trial or had a brain Magnetic Resonance Imaging (MRI) scan demonstrating at least one gadolinium-enhancing (Gd+) lesion within 6 weeks of randomization. The Expanded Disability Status Scale (EDSS) was also assessed and patients could have scores ranging from 0 to 5. Neurological evaluations were performed at baseline, every 3 months, and at the time of suspected relapse. MRI evaluations were performed at baseline, month 6, and year 1 and 2 in a subset of patients (44% in Study 1 and 48% in Study 2). Study 1: Placebo-Controlled Trial in RRMS Study 1 was a 2-year randomized, double-blind, placebo-controlled study in 1234 patients with RRMS. The primary endpoint was the proportion of patients relapsed at 2 years. Additional endpoints at 2 years included the number of new or newly enlarging T2 hyperintense lesions, number of new T1 hypointense lesions, number of Gd+ lesions, annualized relapse rate (ARR), and time to confirmed disability progression. Confirmed disability progression was defined as at least a 1 point increase from baseline EDSS (1.5 point increase for patients with baseline EDSS of 0) sustained for 12 weeks. Patients were randomized to receive dimethyl fumarate 240 mg twice a day (n=410), dimethyl fumarate 240 mg three times a day (n=416), or placebo (n=408) for up to 2 years. The median age was 39 years, median time since diagnosis was 4 years, and median EDSS score at baseline was 2. The median time on study drug for all treatment arms was 96 weeks. The percentages of patients who completed 96 weeks on study drug per treatment group were 69% for patients assigned to dimethyl fumarate 240 mg twice a day, 69% for patients assigned to dimethyl fumarate 240 mg three times a day, and 65% for patients assigned to placebo groups. Dimethyl fumarate had a statistically significant effect on all of the endpoints described above and the 240 mg three times daily dose showed no additional benefit over the dimethyl fumarate 240 mg twice daily dose. The results for this study (240 mg twice a day vs. placebo) are shown in Table 2 and Figure 1 .

The primary endpoint was the annualized relapse rate at 2 years. Additional endpoints at 2 years included the number of new or newly enlarging T2 hyperintense lesions, number of T1 hypointense lesions, number of Gd+ lesions, proportion of patients relapsed, and time to confirmed disability progression as defined in Study 1. Patients were randomized to receive dimethyl fumarate 240 mg twice a day (n=359), dimethyl fumarate 240 mg three times a day (n=345), an open-label comparator (n=350), or placebo (n=363) for up to 2 years. The median age was 37 years, median time since diagnosis was 3 years, and median EDSS score at baseline was 2.5. The median time on study drug for all treatment arms was 96 weeks. The percentages of patients who completed 96 weeks on study drug per treatment group were 70% for patients assigned to dimethyl fumarate 240 mg twice a day, 72% for patients assigned to dimethyl fumarate 240 mg three times a day, and 64% for patients assigned to placebo groups. Dimethyl fumarate had a statistically significant effect on the relapse and MRI endpoints described above. There was no statistically significant effect on disability progression.

Diroximel fumarate is not quantifiable in plasma following oral administration of VUMERITY. Therefore, all pharmacokinetic analyses related to VUMERITY were performed with plasma MMF concentrations. Pharmacokinetic data were obtained in subjects with relapsing forms of multiple sclerosis (MS) and healthy volunteers. Absorption Following oral administration of VUMERITY, the median t max of MMF is 2.5 to 3 hours. The peak plasma concentration (C max ) and overall exposure (AUC) increased dose proportionally in the recommended daily dose range (462 mg to 924 mg). Following administration of VUMERITY 462 mg in patients with MS, the mean C max of MMF was 2.11 mg/L. The mean steady state AUC of MMF was estimated to be 8.32 mg.hr/L following twice daily dosing in patients with MS. Effect of Food In an open-label, randomized, balanced, crossover study, co-administration of VUMERITY with a high-fat, high-calorie meal (900-1000 calories, 50% of calories from fat) did not affect the AUC of MMF, but resulted in an approximately 44% reduction in C max compared to fasted state [see Dosage and Administration ( 2.3 )] . The MMF C max with low-fat, low-calorie (350 to 400 calories, 10 to 15 g fat) and medium-fat, medium-calorie (650 to 700 calories, 25 to 30 g fat) meals was reduced by approximately 12% and 25%, respectively. Relative to fasted state, the t max of MMF was delayed from 2.5 hours (fasted state) to 4.5 hours (low-fat, low-calorie meal or a medium-fat, medium-calorie meal) and 7.0 hours (high-fat, high-calorie meal) in the fed state. There was no impact of low, medium, or high-fat meals on the AUC of MMF after administration of VUMERITY. Distribution The apparent volume of distribution for MMF is between 72 L and 83 L in healthy subjects after administration of VUMERITY. Human plasma protein binding of MMF is 27-45% and independent of concentration. Elimination Metabolism In humans, diroximel fumarate is extensively metabolized by esterases, which are ubiquitous in the gastrointestinal tract, blood, and tissues, to the major active metabolite, MMF, before it reaches the systemic circulation. Further metabolism of MMF occurs through the tricarboxylic acid (TCA) cycle, with no involvement of the cytochrome P450 (CYP) system. Fumaric and citric acid, and glucose are the major metabolites of MMF in plasma. Esterase metabolism of diroximel fumarate also produces 2-hydroxyethyl succinimide (HES), an inactive major metabolite. Excretion MMF is mainly eliminated as carbon dioxide in the expired air with only trace amounts (less than 0.3% of the total dose) recovered in urine. The terminal half-life of MMF is approximately 1 hour, and accumulation of MMF does not occur with multiple doses of VUMERITY. HES is mainly eliminated in urine (58-63% of the dose was excreted as HES in urine). Specific Populations Age (18-79 years), sex, and race (White, African American, and Asian) did not have clinically meaningful effects on the pharmacokinetics of MMF after administration of VUMERITY. The effect of hepatic impairment or severe renal impairment (CrCl <30 mL/min, Cockcroft-Gault) requiring hemodialysis on MMF pharmacokinetics is unknown. Patients with Renal Impairment A single-dose clinical study investigating the effect of renal impairment on the pharmacokinetics of diroximel fumarate and its metabolites MMF and HES was conducted. The study included cohorts with mild, moderate, and severe renal impairment and a healthy cohort (8 subjects per cohort) and found no clinically relevant changes in MMF exposure. However, HES exposure increased by 1.3, 1.8, and 2.7-fold with mild, moderate, and severe renal impairment, respectively, compared to the healthy cohort [see Use in Specific Populations ( 8.6 )] . There are no data available on long-term use of VUMERITY in patients with moderate or severe renal impairment. Patients with Hepatic Impairment No studies have been conducted in subjects with hepatic impairment. However, hepatic impairment would not be expected to affect exposure to MMF and therefore no dosage adjustment is necessary. Drug Interaction Studies Diroximel fumarate metabolism does not involve CYP enzymes, therefore, no clinically meaningful interactions are expected when administered with CYP inhibitors or inducers. In vitro studies found diroximel fumarate and its metabolites did not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4/5 enzymes in human liver microsomes or induce CYP1A2, 2B6, or 3A4/5 in cultured human hepatocytes. Diroximel fumarate did not inhibit P-gp in vivo . The major circulating inactive metabolite of diroximel fumarate, HES, did not inhibit P-gp and was neither a substrate nor an inhibitor of BCRP, MATE1, MATE2-K, OAT1, OAT3, or OCT2. Aspirin, when administered approximately 30 minutes before dimethyl fumarate, did not alter the pharmacokinetics of MMF. Oral Contraceptives In a study conducted with dimethyl fumarate, no relevant effects of MMF on oral contraceptive exposure were observed when administered with a combined oral contraceptive (norelgestromin and ethinyl estradiol). No interaction studies have been performed with oral contraceptives containing other progestogens. Alcohol Administration of VUMERITY at the same time with 5% v/v and 40% v/v ethanol did not alter total MMF exposure relative to administration with water, demonstrating that the coingestion of ethanol does not induce dose dumping. The mean peak plasma MMF concentration for diroximel fumarate was decreased by 9% and 21%, when co-administered with 240 mL of 5% v/v and 40% v/v of ethanol, respectively [see Dosage and Administration ( 2.3 )] . Vaccines A randomized, open-label study examined the concomitant use of dimethyl fumarate (which has the same active metabolite as VUMERITY) and several non-live vaccines in adults 27-55 years of age with relapsing forms of MS (38 subjects undergoing treatment with dimethyl fumarate at the time of vaccination and 33 subjects undergoing treatment with non-pegylated interferon at the time of vaccination). Concomitant exposure to dimethyl fumarate did not attenuate antibody responses to tetanus toxoid-containing vaccine, pneumococcal polysaccharide, and meningococcal vaccines relative to antibody responses in interferon-treated patients. The impact of these findings on vaccine effectiveness in this patient population is unknown. The safety and effectiveness of live or live-attenuated vaccines administered concomitantly with VUMERITY or dimethyl fumarate have not been assessed."],"adverse_reactions":["6 ADVERSE REACTIONS The following important adverse reactions are described elsewhere in labeling: Anaphylaxis and Angioedema [see Warnings and Precautions ( 5.1 )] Progressive Multifocal Leukoencephalopathy [see Warnings and Precautions Section ( 5.2 )] Herpes Zoster and Other Serious Opportunistic Infections [see Warnings and Precautions ( 5.3 )] Lymphopenia [see Warnings and Precautions ( 5.4 )] Liver Injury [see Warnings and Precautions ( 5.6 )] Flushing [see Warnings and Precautions ( 5.6 )] Serious Gastrointestinal Reactions [see Warnings and Precautions ( 5.7 )] Most common adverse reactions (incidence for dimethyl fumarate [which has the same active metabolite as VUMERITY] ≥10% and ≥2% more than placebo) were flushing, abdominal pain, diarrhea, and nausea.

The data described in the following sections were obtained using dimethyl fumarate delayed-release capsules, which has the same active metabolite as VUMERITY. In placebo controlled and uncontrolled clinical studies of dimethyl fumarate (which has the same active metabolite as VUMERITY), a total of 2513 patients have been followed for periods up to 13 years with an overall exposure equivalent to 11,318 person-years. A total of 1169 patients have received at least 5 years of treatment with dimethyl fumarate, and 426 patients have received at least 10 years of treatment with dimethyl fumarate. Adverse Reactions in Placebo-Controlled Trials with Dimethyl Fumarate In the two well-controlled studies demonstrating effectiveness, 1529 patients received dimethyl fumarate with an overall exposure of 2244 person-years [see Clinical Studies ( 14 )]. The adverse reactions presented in Table 1 below are based on safety information from 769 patients treated with dimethyl fumarate 240 mg twice a day and 771 placebo-treated patients. The most common adverse reactions (incidence ≥10% and ≥2% more than placebo) for dimethyl fumarate were flushing, abdominal pain, diarrhea, and nausea.

The incidence of GI events was higher early in the course of treatment (primarily in month 1) and usually decreased over time in patients treated with dimethyl fumarate compared with placebo. Four percent (4%) of patients treated with dimethyl fumarate and less than 1% of placebo patients discontinued due to gastrointestinal events. The incidence of serious GI events was 1% in clinical trial patients treated with dimethyl fumarate; these events, none of which were fatal, included vomiting (0.3%) and abdominal pain (0.3%). Hepatic Transaminases An increased incidence of elevations of hepatic transaminases in patients treated with dimethyl fumarate was seen primarily during the first six months of treatment, and most patients with elevations had levels <3 times the upper limit of normal (ULN) during controlled trials. Elevations of alanine aminotransferase and aspartate aminotransferase to ≥3 times the ULN occurred in a small number of patients treated with both dimethyl fumarate and placebo and were balanced between groups. There were no elevations in transaminases ≥3 times the ULN with concomitant elevations in total bilirubin >2 times the ULN. Discontinuations due to elevated hepatic transaminases were <1% and were similar in patients treated with dimethyl fumarate or placebo. Eosinophilia A transient increase in mean eosinophil counts was seen during the first 2 months of therapy. Adverse Reactions in Clinical Studies with VUMERITY In clinical studies assessing safety in patients with RRMS, approximately 700 patients were treated with VUMERITY and approximately 490 patients received more than 1 year of treatment with VUMERITY. The adverse reaction profile of VUMERITY was consistent with the experience in the placebo-controlled clinical trials with dimethyl fumarate. 6.2 Postmarketing Experience The following adverse reaction has been identified during post approval use of dimethyl fumarate.

Esterase metabolism of diroximel fumarate also produces 2-hydroxyethyl succinimide (HES), an inactive major metabolite. Excretion MMF is mainly eliminated as carbon dioxide in the expired air with only trace amounts (less than 0.3% of the total dose) recovered in urine. The terminal half-life of MMF is approximately 1 hour, and accumulation of MMF does not occur with multiple doses of VUMERITY. HES is mainly eliminated in urine (58-63% of the dose was excreted as HES in urine). Specific Populations Age (18-79 years), sex, and race (White, African American, and Asian) did not have clinically meaningful effects on the pharmacokinetics of MMF after administration of VUMERITY. The effect of hepatic impairment or severe renal impairment (CrCl <30 mL/min, Cockcroft-Gault) requiring hemodialysis on MMF pharmacokinetics is unknown. Patients with Renal Impairment A single-dose clinical study investigating the effect of renal impairment on the pharmacokinetics of diroximel fumarate and its metabolites MMF and HES was conducted. The study included cohorts with mild, moderate, and severe renal impairment and a healthy cohort (8 subjects per cohort) and found no clinically relevant changes in MMF exposure. However, HES exposure increased by 1.3, 1.8, and 2.7-fold with mild, moderate, and severe renal impairment, respectively, compared to the healthy cohort [see Use in Specific Populations ( 8.6 )] . There are no data available on long-term use of VUMERITY in patients with moderate or severe renal impairment. Patients with Hepatic Impairment No studies have been conducted in subjects with hepatic impairment. However, hepatic impairment would not be expected to affect exposure to MMF and therefore no dosage adjustment is necessary. Drug Interaction Studies Diroximel fumarate metabolism does not involve CYP enzymes, therefore, no clinically meaningful interactions are expected when administered with CYP inhibitors or inducers. In vitro studies found diroximel fumarate and its metabolites did not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4/5 enzymes in human liver microsomes or induce CYP1A2, 2B6, or 3A4/5 in cultured human hepatocytes. Diroximel fumarate did not inhibit P-gp in vivo . The major circulating inactive metabolite of diroximel fumarate, HES, did not inhibit P-gp and was neither a substrate nor an inhibitor of BCRP, MATE1, MATE2-K, OAT1, OAT3, or OCT2. Aspirin, when administered approximately 30 minutes before dimethyl fumarate, did not alter the pharmacokinetics of MMF. Oral Contraceptives In a study conducted with dimethyl fumarate, no relevant effects of MMF on oral contraceptive exposure were observed when administered with a combined oral contraceptive (norelgestromin and ethinyl estradiol). No interaction studies have been performed with oral contraceptives containing other progestogens. Alcohol Administration of VUMERITY at the same time with 5% v/v and 40% v/v ethanol did not alter total MMF exposure relative to administration with water, demonstrating that the coingestion of ethanol does not induce dose dumping. The mean peak plasma MMF concentration for diroximel fumarate was decreased by 9% and 21%, when co-administered with 240 mL of 5% v/v and 40% v/v of ethanol, respectively [see Dosage and Administration ( 2.3 )] . Vaccines A randomized, open-label study examined the concomitant use of dimethyl fumarate (which has the same active metabolite as VUMERITY) and several non-live vaccines in adults 27-55 years of age with relapsing forms of MS (38 subjects undergoing treatment with dimethyl fumarate at the time of vaccination and 33 subjects undergoing treatment with non-pegylated interferon at the time of vaccination). Concomitant exposure to dimethyl fumarate did not attenuate antibody responses to tetanus toxoid-containing vaccine, pneumococcal polysaccharide, and meningococcal vaccines relative to antibody responses in interferon-treated patients. The impact of these findings on vaccine effectiveness in this patient population is unknown. The safety and effectiveness of live or live-attenuated vaccines administered concomitantly with VUMERITY or dimethyl fumarate have not been assessed."],"indications_and_usage":["1 INDICATIONS AND USAGE VUMERITY is indicated for the treatment of relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.

( 1 )"],"warnings_and_cautions":["5 WARNINGS AND PRECAUTIONS Anaphylaxis and Angioedema: Discontinue and do not restart VUMERITY if these occur. ( 5.1 ) Progressive Multifocal Leukoencephalopathy (PML): Withhold VUMERITY at the first sign or symptom suggestive of PML. ( 5.2 ) Herpes Zoster and Other Serious Opportunistic Infections: Consider withholding VUMERITY in cases of serious infection until the infection has resolved. ( 5.3 ) Lymphopenia: Obtain a CBC including lymphocyte count before initiating VUMERITY, after 6 months, and every 6 to 12 months thereafter. Consider interruption of VUMERITY if lymphocyte counts <0.5 × 10 9 /L persist for more than six months. ( 5.4 ) Liver Injury: Obtain serum aminotransferase, alkaline phosphatase, and total bilirubin levels before initiating VUMERITY and during treatment, as clinically indicated. Discontinue VUMERITY if clinically significant liver injury induced by VUMERITY is suspected. ( 5.6 ) 5.1 Anaphylaxis and Angioedema VUMERITY can cause anaphylaxis and angioedema after the first dose or at any time during treatment. Signs and symptoms in patients taking dimethyl fumarate (which has the same active metabolite as VUMERITY) have included difficulty breathing, urticaria, and swelling of the throat and tongue. Patients should be instructed to discontinue VUMERITY and seek immediate medical care should they experience signs and symptoms of anaphylaxis or angioedema. 5.2 Progressive Multifocal Leukoencephalopathy Progressive multifocal leukoencephalopathy (PML) has occurred in patients with MS treated with dimethyl fumarate (which has the same active metabolite as VUMERITY). PML is an opportunistic viral infection of the brain caused by the JC virus (JCV) that typically only occurs in patients who are immunocompromised, and that usually leads to death or severe disability. A fatal case of PML occurred in a patient who received dimethyl fumarate for 4 years while enrolled in a clinical trial. During the clinical trial, the patient experienced prolonged lymphopenia (lymphocyte counts predominantly <0.5 × 10 9 /L for 3.5 years) while taking dimethyl fumarate [see Warnings and Precautions ( 5.4 )]. The patient had no other identified systemic medical conditions resulting in compromised immune system function and had not previously been treated with natalizumab, which has a known association with PML. The patient was also not taking any immunosuppressive or immunomodulatory medications concomitantly. PML has also occurred in patients taking dimethyl fumarate in the postmarketing setting in the presence of lymphopenia (<0.9 × 10 9 /L). While the role of lymphopenia in these cases is uncertain, the PML cases have occurred predominantly in patients with lymphocyte counts <0.8×10 9 /L persisting for more than 6 months. At the first sign or symptom suggestive of PML, withhold VUMERITY and perform an appropriate diagnostic evaluation. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes. Magnetic resonance imaging (MRI) findings may be apparent before clinical signs or symptoms. Cases of PML diagnosed based on MRI findings and the detection of JCV DNA in the cerebrospinal fluid in the absence of clinical signs or symptoms specific to PML, have been reported in patients treated with other MS medications associated with PML. Many of these patients subsequently became symptomatic with PML. Therefore, monitoring with MRI for signs that may be consistent with PML may be useful, and any suspicious findings should lead to further investigation to allow for an early diagnosis of PML, if present. Lower PML-related mortality and morbidity have been reported following discontinuation of another MS medication associated with PML in patients with PML who were initially asymptomatic compared to patients with PML who had characteristic clinical signs and symptoms at diagnosis. It is not known whether these differences are due to early detection and discontinuation of MS treatment or due to differences in disease in these patients. 5.3 Herpes Zoster and Other Serious Opportunistic Infections Serious cases of herpes zoster have occurred in patients treated with dimethyl fumarate (which has the same active metabolite as VUMERITY) including disseminated herpes zoster, herpes zoster ophthalmicus, herpes zoster meningoencephalitis, and herpes zoster meningomyelitis. These events may occur at any time during treatment. Monitor patients on VUMERITY for signs and symptoms of herpes zoster. If herpes zoster occurs, appropriate treatment for herpes zoster should be administered. Other serious opportunistic infections have occurred with dimethyl fumarate, including cases of serious viral (herpes simplex virus, West Nile virus, cytomegalovirus), fungal (Candida and Aspergillus), and bacterial (Nocardia, Listeria monocytogenes, Mycobacterium tuberculosis) infections. These infections have been reported in patients with reduced absolute lymphocyte counts (ALC) as well as in patients with normal ALC. These infections have affected the brain, meninges, spinal cord, gastrointestinal tract, lungs, skin, eye, and ear. Patients with symptoms and signs consistent with any of these infections should undergo prompt diagnostic evaluation and receive appropriate treatment. Consider withholding VUMERITY treatment in patients with herpes zoster or other serious infections until the infection has resolved [see Adverse Reactions ( 6.2 )] . 5.4 Lymphopenia VUMERITY may decrease lymphocyte counts. In the MS placebo-controlled trials with dimethyl fumarate (which has the same active metabolite as VUMERITY), mean lymphocyte counts decreased by approximately 30% during the first year of treatment with dimethyl fumarate and then remained stable. Four weeks after stopping dimethyl fumarate, mean lymphocyte counts increased but did not return to baseline. Six percent (6%) of dimethyl fumarate patients and <1% of placebo patients experienced lymphocyte counts <0.5 × 10 9 /L (lower limit of normal 0.91 × 10 9 /L). The incidence of infections (60% vs 58%) and serious infections (2% vs 2%) was similar in patients treated with dimethyl fumarate or placebo, respectively. There was no increased incidence of serious infections observed in patients with lymphocyte counts <0.8 × 10 9 /L or ≤0.5 × 10 9 /L in controlled trials, although one patient in an extension study developed PML in the setting of prolonged lymphopenia (lymphocyte counts predominantly <0.5 × 10 9 /L for 3.5 years) [see Warnings and Precautions ( 5.2 )] . In controlled and uncontrolled clinical trials with dimethyl fumarate, 2% of patients experienced prolonged, severe lymphopenia, (defined as lymphocyte counts <0.5 x 10 9 /L for at least six months); in this group of patients, the majority of lymphocyte counts remained <0.5 x 10 9 /L with continued therapy. In these patients with prolonged, severe lymphopenia, the median time for lymphocyte counts to return to normal after discontinuing dimethyl fumarate was 96.0 weeks. In these controlled and uncontrolled clinical studies, among patients who did not experience prolonged, severe lymphopenia during treatment, the median times for lymphocyte counts to return to normal after discontinuing dimethyl fumarate were as follows: 4.3 weeks in patients with mild lymphopenia (lymphocyte count ≥0.8 x 10 9 /L) at discontinuation, 10.0 weeks in patients with moderate lymphopenia (lymphocyte count 0.5 to <0.8 x 10 9 /L) at discontinuation, and 16.7 weeks in patients with severe lymphopenia (lymphocyte count <0.5 x 10 9 /L) at discontinuation. Neither VUMERITY nor dimethyl fumarate have been studied in patients with preexisting low lymphocyte counts. Obtain a complete blood count (CBC), including lymphocyte count, before initiating treatment with VUMERITY, 6 months after starting treatment, and then every 6 to 12 months thereafter, and as clinically indicated. Consider interruption of VUMERITY in patients with lymphocyte counts less than 0.5 × 10 9 /L persisting for more than six months. Given the potential for delayed recovery of lymphocyte counts, continue to obtain lymphocyte counts until their recovery if VUMERITY is discontinued or interrupted because of lymphopenia. Consider withholding treatment from patients with serious infections until resolution. Decisions about whether or not to restart VUMERITY should be individualized based on clinical circumstances. 5.5 Liver Injury Clinically significant cases of liver injury have been reported in patients treated with dimethyl fumarate (which has the same active metabolite as VUMERITY) in the postmarketing setting. The onset has ranged from a few days to several months after initiation of treatment with dimethyl fumarate. Signs and symptoms of liver injury, including elevation of serum aminotransferases to greater than 5-fold the upper limit of normal and elevation of total bilirubin to greater than 2-fold the upper limit of normal have been observed. These abnormalities resolved upon treatment discontinuation. Some cases required hospitalization. None of the reported cases resulted in liver failure, liver transplant, or death. However, the combination of new serum aminotransferase elevations with increased levels of bilirubin caused by drug-induced hepatocellular injury is an important predictor of serious liver injury that may lead to acute liver failure, liver transplant, or death in some patients. Elevations of hepatic transaminases (most no greater than 3 times the upper limit of normal) were observed during controlled trials with dimethyl fumarate [see Adverse Reactions ( 6.1 )] . Obtain serum aminotransferase, alkaline phosphatase (ALP), and total bilirubin levels prior to treatment with VUMERITY and during treatment, as clinically indicated. Discontinue VUMERITY if clinically significant liver injury induced by VUMERITY is suspected. 5.6 Flushing VUMERITY may cause flushing (e.g., warmth, redness, itching, and/or burning sensation). In clinical trials of dimethyl fumarate (which has the same active metabolite as VUMERITY), 40% of dimethyl fumarate-treated patients experienced flushing. Flushing symptoms generally began soon after initiating dimethyl fumarate and usually improved or resolved over time. In the majority of patients who experienced flushing, it was mild or moderate in severity. Three percent (3%) of patients discontinued dimethyl fumarate for flushing and <1% had serious flushing symptoms that were not life-threatening but led to hospitalization. Administration of VUMERITY with food may reduce the incidence of flushing [see Dosage and Administration ( 2.3 )] . Studies with dimethyl fumarate show that administration of non-enteric coated aspirin (up to a dose of 325 mg) 30 minutes prior to dosing may reduce the incidence or severity of flushing [see Clinical Pharmacology ( 12.3 )] . 5.7 Serious Gastrointestinal Reactions Serious gastrointestinal reactions, including perforation, ulceration, hemorrhage, and obstruction, some with fatal outcomes, have been reported in the postmarketing setting with the use of fumaric acid esters, including VUMERITY, with or without concomitant aspirin use. The majority of these events have occurred within 6 months of fumaric acid ester treatment initiation. In controlled clinical trials, the incidence of serious gastrointestinal adverse reactions was 1% in patients treated with dimethyl fumarate; these events, none of which were fatal, included vomiting (0.3%) and abdominal pain (0.3%) [see Adverse Reactions ( 6.1 )] . Monitor patients, promptly evaluate, and discontinue VUMERITY for new or worsening severe gastrointestinal signs and symptoms."],"clinical_studies_table":["

"],"nonclinical_toxicology":["13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Oral administration of diroximel fumarate (0, 0, 30, 100, 300 or 1000 [females only] mg/kg/day) for 26 weeks to Tg.rasH2 mice resulted in no drug-related tumors. Oral administration of diroximel fumarate (0, 0, 15, 50, or 150 mg/kg/day) to male and female rats resulted in an increase in tumors (Leydig cell adenomas of the testes) in males at the highest dose tested. At the higher dose (50 mg/kg/day) not associated with drug-related tumors, plasma exposures for MMF and HES (the major circulating drug-related compound in humans) were similar to (MMF) and less than (HES) those in humans at the recommended human dose (RHD) of 924 mg/day. Mutagenesis Diroximel fumarate was negative in the in vitro bacterial reverse mutation and in vivo rat micronucleus and comet assays. Diroximel fumarate was clastogenic (in the absence and presence of metabolic activation) in the in vitro chromosomal aberration assay in human peripheral blood lymphocytes. Impairment of Fertility No adverse effects on fertility were observed following oral administration of diroximel fumarate to male rats (0, 40, 120, or 400 mg/kg/day) prior to and during mating with untreated females and, in a separate study, to female rats (0, 40, 120, or 450 mg/kg/day) prior to and during mating with untreated males and continuing to Gestation Day (GD) 7. At the highest doses tested, plasma exposures (AUC) for MMF were approximately 7-9 times that in humans at the RHD. Plasma levels of HES were not quantitated. 13.2 Animal Toxicology and/or Pharmacology Kidney toxicity, including tubular changes (degeneration, necrosis, regeneration, hypertrophy) and/or interstitial fibrosis, were observed following oral administration of diroximel fumarate in rats and monkeys. In the chronic toxicology study in rats (0, 50, 100, or 300 mg/kg/day), adverse renal findings occurred at all doses tested. Plasma exposures (AUC) at the low dose (50 mg/kg/day) were similar to (MMF) or less than (HES) those in humans at the RHD. In the chronic toxicology study in monkeys (0, 15, 50, or 150 mg/kg/day), adverse renal findings occurred at all but the lowest dose tested (15 mg/kg/day), which was associated with plasma MMF and HES exposures (AUC) less than those in humans at the RHD."],"adverse_reactions_table":["

( 8.1 ) VUMERITY is not recommended in patients with moderate or severe renal impairment. ( 8.6 ) 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to VUMERITY during pregnancy. Encourage patients to enroll by calling 1-833-569-2635 or visiting www.vumeritypregnancyregistry.com. Risk Summary There are no adequate data on the developmental risk associated with the use of VUMERITY in pregnant women. Available data from a pregnancy registry for dimethyl fumarate (which has the same active metabolite as VUMERITY), observational studies, and pharmacovigilance pertaining to dimethyl fumarate use in pregnant women have not indicated an increased risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Most of the reported exposures to dimethyl fumarate occurred during the first trimester of pregnancy (see Data ). In animal studies, administration of diroximel fumarate during pregnancy or throughout pregnancy and lactation resulted in adverse effects on embryofetal and offspring development (increased incidences of skeletal abnormalities, increased mortality, decreased body weights, neurobehavioral impairment) at clinically relevant drug exposures [ see Data ]. The 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. Data Human Data In a prospective observational pregnancy registry for dimethyl fumarate (2013-2022), the rate of major birth defects among 362 live births and stillbirths from women who were exposed to dimethyl fumarate during pregnancy was 3.6% (95% CI: 1.9-6.1). No specific pattern of major birth defects was identified. Important potential study limitations include exposure misclassification, no adjustment for confounders, and lack of an internal comparator cohort. Animal Data Oral administration of diroximel fumarate (0, 40, 100, or 400 mg/kg/day) to pregnant rats throughout organogenesis resulted in a decrease in fetal body weight and an increase in fetal skeletal variations at the highest dose tested, which was associated with maternal toxicity. Plasma exposures (AUC) for MMF and HES (the major circulating drug-related compound in humans) at the no-effect dose (100 mg/kg/day) for adverse effects on embryofetal development were approximately 2 times those in humans at the recommended human dose (RHD) of 924 mg/day. Oral administration of diroximel fumarate (0, 50, 150, or 350 mg/kg/day) to pregnant rabbits throughout organogenesis resulted in an increase in fetal skeletal malformations at the mid and high doses and reduced fetal body weight and increases in embryofetal death and fetal skeletal variations at the highest dose tested. The high dose was associated with maternal toxicity. Plasma exposures (AUC) for MMF and HES at the no-effect dose (50 mg/kg/day) for adverse effects on embryofetal development were similar to (MMF) or less than (HES) those in humans at the RHD. Oral administration of diroximel fumarate (0, 40, 100, or 400 mg/kg/day) to rats throughout gestation and lactation resulted in reduced weight, which persisted into adulthood, and adverse effects on neurobehavioral function in offspring at the highest dose tested. Plasma exposures (AUC) for MMF and HES at the no-effect dose for adverse effects on postnatal development (100 mg/kg/day) were approximately 3 times (MMF) or similar to (HES) those in humans at the RHD. 8.2 Lactation Risk Summary There are no data on the presence of diroximel fumarate or metabolites (MMF, HES) in human milk. The effects on the breastfed infant and on milk production are unknown. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for VUMERITY and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use Clinical studies of dimethyl fumarate and VUMERITY did not include sufficient numbers of patients aged 65 years and over to determine whether they respond differently from younger patients. 8.6 Renal Impairment No dosage adjustment is necessary in patients with mild renal impairment. Because of an increase in the exposure of a major metabolite [2-hydroxyethyl succinimide (HES)], use of VUMERITY is not recommended in patients with moderate or severe renal impairment [see Clinical Pharmacology ( 12.3 )] ."],"spl_patient_package_insert_table":["
