AAN EXCELLENCE—DELIVERED UNCONVENTIONALLY

"

It’s time to get excited about the upcoming AAN Annual Meeting Science Program! To address the time demands of virtual programming, we trimmed the number of scientific sessions, but kept all the key elements of the program—most importantly, the Plenaries, Neuroscience in the Clinic, and the Invited Science sessions will once again be front and center. In addition to the cutting-edge original science, this year’s program also brings into focus some of the most relevant issues of our times, such as neurologic complications of COVID-19, the effects of the pandemic on the field of neurology, health care disparities, and the neurologic sequelae of systemic racism.

"

A special bonus to being able to see each other virtually is that so many of our friends and colleagues, who otherwise would not have been able to travel across the world, will now be able to join us at the click of a button! This makes the 2021 #AANAM a truly global meeting—accessible, equitable, and indispensable to neurologists and neuroscientists everywhere.

I am looking forward to coming together as a community that is fueled by science!

Natalia S. Rost, MD, MPH, FAAN, FAHA Chair, Science Committee

metabolic, immune, and reproductive—that influence susceptibility to neurological and neuropsychiatric disease. In this Neuroscience in Clinic Session, we will examine the neuroepidemiology of obesity, specifically the role of obesity as a risk factor for neurology diseases; neuropsychiatric and metabolic manifestations of obesity; and shared neural pathways in body weight regulation with neurological disease, as uncovered by genetics. Our invited scientists will review specific endocrine (including adipokines), neural, and other mechanisms of obesity and their relation to neurological diseases.

Finally, we will discuss obesity treatments including dietary interventions (e.g., very low energy diets, intermittent fasting), pharmacotherapy (e.g., GLP-1 analogs, growth hormone treatment), and bariatric surgery. Outcomes that will be discussed include Alzheimer's Disease and Related Dementias (ADRD), cerebral small vessel disease, depression, schizophrenia, attention deficit hyperactivity disorder (ADHD), autism, multiple sclerosis, and Huntington's Disease.

until recently that cancer cells have been proven to be immunogenic. And now treatments based on this concept have translated into treatments that improve survival in cancer patients. There are a growing number of FDA approved drugs that target the immune system as their anti-neoplastic mechanism of action. However, neurologic side effects are common with many of these new treatments. In this session, faculty will present a challenging case of neurotoxicity after CAR-T cell therapy. Faculty will review the basic science behind cancer immunotherapy and neurologic side effects of immunotherapy.

NEUROSCIENCE IN THE CLINIC SESSIONS

Description: Adults and children with neurologic disorders such as epilepsy, migraine, autism, Parkinson’s,

stroke, and concussion often experience significantly disrupted sleep. There is accumulating evidence suggesting that melatonin may play a role in this interaction between neurologic disorders and sleep disruption. This program will address what is known about the role of melatonin in brain activity, and how this may pertain to fluctuations in neurologic function and sleep abnormalities. The program will draw on examples from multiple sclerosis, Parkinson’s, autism, headache, epilepsy, cerebrovascular disease, and other neurologic conditions. The program will also emphasize potential approaches to modulating the effect of melatonin to optimize sleep and treatment of neurologic disorders.

GOCOVRI® COULD MEAN THE DIFFERENCE

GOCOVRI® is now FDA approved to also treat OFF episodes in patients taking levodopa1

BETWEEN GETTING UP

AND GETTING OUT GOCOVRI® is ready when your Parkinson’s disease (PD) patients with dyskinesia or OFF episodes need it.1,2 With a single bedtime dose, high levels of GOCOVRI® are reached by morning before the first levodopa dose, providing all-day coverage with levels slowly decreasing in the hours before bedtime.2 In clinical trials, GOCOVRI® reduced PD dyskinesia (primary endpoint) and OFF time and increased GOOD ON time (secondary endpoints).1 * Not an actual patient.

27% DECREASE IN DYSKINESIA 36% DECREASE IN OFF TIME 29% INCREASE IN GOOD ON TIME

10.1-point reduction in UDysRS score (-17.7 GOCOVRI® vs -7.6 placebo) 3†

1-hour decrease (-0.6 GOCOVRI® vs 0.4 placebo) 3,4†

2.4-hour increase (3.8 GOCOVRI® vs 1.4 placebo) 3,4†

GOOD ON time, ON time without troublesome dyskinesia; UDysRS, Unified Dyskinesia Rating Scale.

Visit GocovriHCP.com to learn more.

*As seen in pooled results of 2 independently positive, pivotal, Phase 3, randomized, placebo-controlled trials (Study 1 and Study 2) in PD patients on levodopa. Study 1, a 24-week study, was conducted in 121 PD patients with dyskinesia (GOCOVRI® [n = 63], placebo [n = 58]). Study 2, a 12-week study, was conducted in 75 PD patients with dyskinesia (GOCOVRI® [n = 37], placebo [n = 38]).1,3 † In Study 1, GOCOVRI® reduced the UDysRS total score by 15.9 points (vs 8.0 with placebo) (P = 0.0009), decreased OFF time by 0.6 hours (vs an increase of 0.3 hours with placebo) (P = 0.0171), and increased GOOD ON time by 3.6 hours (vs 0.8 hours with placebo) (P < 0.0001) from baseline. In Study 2, GOCOVRI® reduced the UDysRS total score by 20.7 points (vs 6.3 with placebo) (P < 0.0001), decreased OFF time by 0.5 hours (vs an increase of 0.6 hours with placebo) (P = 0.0199), and increased GOOD ON time by 4.0 hours (vs 2.1 hours with placebo) (P = 0.0168) from baseline.1

INDICATION GOCOVRI® (amantadine) extended release capsules is indicated: • For the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications • As adjunctive treatment to levodopa/carbidopa in patients with Parkinson’s disease experiencing “off” episodes It is not known if GOCOVRI is safe and effective in children.

IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS GOCOVRI is contraindicated in patients with creatinine clearance below 15 mL/min/1.73 m2.

WARNINGS AND PRECAUTIONS Falling Asleep During Activities of Daily Living and Somnolence: Patients treated with Parkinson’s disease medications have reported falling asleep during activities of daily living. If a patient develops daytime sleepiness during activities that require full attention (e.g., driving a motor vehicle, conversations, eating), GOCOVRI should ordinarily be discontinued or the patient should be advised to avoid potentially dangerous activities.

Suicidality and Depression: Monitor patients for depression, including suicidal ideation or behavior. Prescribers should consider whether the benefits outweigh the risks of treatment with GOCOVRI in patients with a history of suicidality or depression.

Hallucinations/Psychotic Behavior: Patients with a major psychotic disorder should ordinarily not be treated with GOCOVRI because of the risk of exacerbating psychosis. Observe patients for the occurrence of hallucinations throughout treatment, especially at initiation and after dose increases.

Dizziness and Orthostatic Hypotension: Monitor patients for dizziness and orthostatic hypotension, especially after starting GOCOVRI or increasing the dose.

Withdrawal-Emergent Hyperpyrexia and Confusion: Rapid dose reduction or abrupt discontinuation of GOCOVRI, may cause an increase in the symptoms of Parkinson’s disease or cause delirium, agitation, delusions, hallucinations, paranoid reaction, stupor, anxiety, depression, or slurred speech. Avoid sudden discontinuation of GOCOVRI. Impulse Control/Compulsive Behaviors: Patients may experience urges (e.g. gambling, sexual, money spending, binge eating) and the inability to control them. It is important for prescribers to ask patients or their caregivers about the development of new or increased urges.

Consider dose reduction or stopping medications.

ADVERSE REACTIONS The most common adverse reactions (>10%) were hallucination, dizziness, dry mouth, peripheral edema, constipation, fall, and orthostatic hypotension.

Other clinically relevant adverse reactions observed at <3% included somnolence, fatigue, suicide ideation or attempt, apathy, delusions, illusions, and paranoia.

Difference in the Frequency of Adverse Reactions by Gender in Patients Treated With GOCOVRI Adverse reactions reported more frequently in women (n=46) vs men (n=54) were: dry mouth (22% vs 11%), nausea (13% vs 4%), livedo reticularis (13% vs 0%), abnormal dreams (9% vs 0%), and cataracts (7% vs 0%), respectively. Men vs women reported the following adverse reactions more frequently: dizziness (20% vs 11%), peripheral edema (19% vs 11%), anxiety (11% vs 2%), orthostatic hypotension (7% vs 2%), and gait disturbance (6% vs 0%), respectively.

Difference in the Frequency of Adverse Reactions by Age in Patients Treated With GOCOVRI Hallucinations (visual or auditory) were reported in 31% of patients age 65 years and over (n=52) vs 10 % in patients below the age of 65 years (n=48). Falls were reported in 17% of patients age 65 and over vs 8% of patients below age 65. Orthostatic hypotension was reported in 8% of patients age 65 and over compared with 2% of patients below age 65.

DRUG INTERACTIONS: Other Anticholinergic Drugs: Products with anticholinergic properties may potentiate the anticholinergic-like side effects of amantadine. The dose of anticholinergic drugs or of GOCOVRI should be reduced if atropine-like effects appear when these drugs are used concurrently.

Drugs Affecting Urinary pH: The pH of the urine has been reported to influence the excretion rate of amantadine. Urine pH is altered by diet, drugs (eg, carbonic anhydrase inhibitors, sodium bicarbonate), and clinical state of the patient (eg, renal tubular acidosis or severe infections of the urinary tract). Since the excretion rate of amantadine increases rapidly when the urine is acidic, the administration of urine acidifying drugs may increase the elimination of the drug from the body. Alterations of urine pH towards the alkaline condition may lead to an accumulation of the drug with a possible increase in adverse reactions. Monitor for efficacy or adverse reactions under conditions that alter the urine pH to more acidic or alkaline, respectively.

Live Attenuated Influenza Vaccines: Due to its antiviral properties, amantadine may interfere with the efficacy of live attenuated influenza vaccines. Therefore, live vaccines are not recommended during treatment with GOCOVRI. Inactivated influenza vaccines may be used, as appropriate.

Alcohol: Concomitant use with alcohol is not recommended, as it may increase the potential for CNS effects such as dizziness, confusion, lightheadedness, and orthostatic hypotension, and may result in dose-dumping.

USE IN SPECIFIC POPULATIONS: Pregnancy: There are no adequate data on the developmental risk associated with use of amantadine in pregnant women. Based on animal data, it may cause fetal harm.

Lactation: Amantadine is excreted into human milk, but amounts have not been quantified. There is no information on the risk to a breastfed infant. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for GOCOVRI and any potential adverse effects on the breastfed infant from GOCOVRI or from the underlying maternal condition.

Pediatric Use: Safety and effectiveness of GOCOVRI in pediatric patients have not been established.

Geriatric Use: In Phase 3 clinical trials, the mean age of patients at study entry was 65 years. Of the total number of patients in clinical studies of GOCOVRI, 46% were less than 65 years of age, 39% were 65-74 years of age, and 15% were 75 years of age or older.

Hallucinations and falls occurred more frequently in patients 65 years of age or older, compared with those less than 65 years of age. No dose adjustment is recommended on the basis of age. GOCOVRI is known to be substantially excreted by the kidney, and the risk of adverse reactions may be greater in patients with impaired renal function.

Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

Renal Impairment: GOCOVRI is contraindicated for use in patients with end-stage renal disease (creatinine clearance values lower than 15 mL/min/1.73 m2). A 50% dose reduction of GOCOVRI to a starting daily dose of 68.5 mg daily for a week, followed by a daily maintenance dose of 137 mg is recommended in patients with moderate renal impairment (creatinine clearance between 30 and 59 mL/min/1.73 m2). For patients with severe renal impairment (creatinine clearance between 15 and 29 mL/min/1.73 m2), a daily dose of 68.5 mg is recommended.

Overdosage: Deaths have been reported from overdose with amantadine immediaterelease. The lowest reported acute lethal dose was 1 g of amantadine hydrochloride (equivalent to 0.8 g amantadine). Acute toxicity may be attributable to the anticholinergic effects of amantadine. Drug overdose has resulted in cardiac, respiratory, renal, or central nervous system toxicity. Pulmonary edema and respiratory distress (including adult respiratory distress syndrome, ARDS) have been reported with amantadine; renal dysfunction, including increased BUN and decreased creatinine clearance, can occur. Central nervous system effects that have been reported with overdose include agitation, aggressive behavior, hypertonia, hyperkinesia, ataxia, tremor, disorientation, depersonalization, fear, delirium, psychotic reactions, lethargy, and coma. Seizures may be exacerbated in patients with prior history of seizure disorders. Hyperthermia has occurred with amantadine overdose. For acute overdosing, general supportive measures should be employed along with immediate gastric decontamination if appropriate. Give intravenous fluids if necessary. The excretion rate of amantadine increases with acidification of urine, which may increase the elimination of the drug. Monitor patients for arrhythmias and hypotension. Electrocardiographic monitoring may be needed after ingestion because arrhythmias have been reported after overdose, including arrhythmias with fatal outcomes. Adrenergic agents, such as isoproterenol, in patients with an amantadine overdose has been reported to induce arrhythmias. Monitor blood electrolytes, urine pH, and urinary output. Although amantadine is not efficiently removed by hemodialysis, this procedure may be useful in the treatment of amantadine toxicity in patients with renal failure.

GOCOVRI® (amantadine) extended release capsules Brief Summary of full Prescribing Information. See full Prescribing Information.

Rx Only.

INDICATIONS AND USAGE: GOCOVRI® (amantadine) extended release capsules is indicated: • For the treatment of dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy, with or without concomitant dopaminergic medications • As adjunctive treatment to levodopa/carbidopa in patients with Parkinson’s disease experiencing “off” episodes CONTRAINDICATIONS: Contraindicated in patients with creatinine clearance below 15 mL/min/1.73 m2 WARNINGS AND PRECAUTIONS: Falling Asleep During Activities of Daily Living and Somnolence: Patients treated with Parkinson’s disease medications have reported falling asleep while engaged in activities of daily living, including the operation of motor vehicles, which sometimes has resulted in accidents. Patients may not perceive warning signs, such as excessive drowsiness, or they may report feeling alert immediately prior to the event. In controlled clinical trials, somnolence and fatigue were reported in 4% vs 1% of patients treated with GOCOVRI or placebo, respectively. Before initiating treatment with GOCOVRI, advise patients of the potential to develop drowsiness and specifically ask about factors that may increase the risk for somnolence with GOCOVRI, such as concomitant sedating medications or the presence of a sleep disorder. If a patient develops daytime sleepiness or episodes of falling asleep during activities that require full attention (eg, driving a motor vehicle, conversations, eating), GOCOVRI should ordinarily be discontinued. If a decision is made to continue GOCOVRI, patients should be advised not to drive and to avoid other potentially dangerous activities. There is insufficient information to establish whether dose reduction will eliminate episodes of falling asleep while engaged in activities of daily living or daytime somnolence.

Suicidality and Depression: In controlled clinical trials, suicidal ideation or suicide attempt was reported in 2% vs 0%; depression or depressed mood 6% vs 1%; confusional state 3% vs 2%; apathy 2% vs 0%, of patients treated with GOCOVRI or placebo, respectively. Monitor patients for depression, including suicidal ideation or behavior. Prescribers should consider whether the benefits outweigh the risks of treatment with GOCOVRI in patients with a history of suicidality or depression.

Hallucinations/Psychotic Behavior: Patients with a major psychotic disorder should ordinarily not be treated with GOCOVRI because of the risk of exacerbating psychosis.

In controlled trials, the incidence of patients who experienced visual hallucination, auditory hallucination, delusions, illusions, or paranoia was 25% vs 3%; hallucinations caused discontinuation of treatment in 8% vs 0%; of patients treated with GOCOVRI or placebo, respectively. Observe patients for the occurrence of hallucinations throughout treatment, especially at initiation and after dose increases.

Dizziness and Orthostatic Hypotension: In controlled clinical trials, 29% vs 2% experienced dizziness, syncope, orthostatic hypotension, presyncope, postural dizziness or hypotension; and 3% vs 0% discontinued study treatment because of dizziness, postural dizziness, or syncope; of patients receiving GOCOVRI or placebo, respectively. Monitor patients for dizziness and orthostatic hypotension, especially after starting GOCOVRI or increasing the dose. Concomitant use of alcohol with GOCOVRI is not recommended.

Withdrawal-Emergent Hyperpyrexia and Confusion: A symptom complex resembling neuroleptic malignant syndrome (characterized by elevated temperature, muscular rigidity, altered consciousness, and autonomic instability), with no other obvious etiology, has been reported in association with rapid dose reduction, withdrawal of, or changes in drugs that increase central dopaminergic tone. Abrupt discontinuation of GOCOVRI may cause an increase in the symptoms of Parkinson’s disease or cause delirium, agitation, delusions, hallucinations, paranoid reaction, stupor, anxiety, depression, or slurred speech. If possible, avoid sudden discontinuation of GOCOVRI. Impulse Control/Compulsive Behaviors: Patients can experience intense urges to gamble, increased sexual urges, intense urges to spend money, binge eating, and/or other intense urges, and the inability to control these urges while taking one or more of the medications, including GOCOVRI, that increase central dopaminergic tone. In some cases, these urges were reported to have stopped when the dose was reduced or the medication was discontinued. Because patients may not recognize these behaviors as abnormal, it is important for prescribers to specifically ask patients or their caregivers about the development of such urges, and to consider dose reduction or stopping GOCOVRI treatment.

ADVERSE REACTIONS: Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.

GOCOVRI was evaluated in 2 double-blind, placebo-controlled efficacy trials of similar design and population: Study 1 (123 patients) and Study 2 (75 patients). The study population was approximately 56% male and 94% white, with a mean age of 65 years (age range from 34 years to 82 years). The mean duration of levodopa-induced dyskinesia was 4 years (range 0.1 to 14 years). Active treatment started at 137 mg once daily for 1 week, followed by a dose increase to 274 mg once daily. The treatment duration was 25 weeks for Study 1 and 13 weeks for Study 2. Study 1 was stopped prematurely unrelated to safety, with 39/100 patients (safety population) treated with GOCOVRI for 24 weeks.

The most common adverse reactions reported in >10% of GOCOVRI-treated patients and more frequently than on placebo were: hallucination, dizziness, dry mouth, peripheral edema, constipation, falls, and orthostatic hypotension.

The overall rate of discontinuation because of adverse reactions was 20% vs 8% for patients treated with GOCOVRI or placebo, respectively. Adverse reactions that led to treatment discontinuation in at least 2% of patients were hallucination (8% GOCOVRI vs 0% placebo), dry mouth (3% GOCOVRI vs 0% placebo), peripheral edema (3% GOCOVRI vs 0% placebo), blurred vision (3% GOCOVRI vs 0% placebo), postural dizziness and syncope (2% GOCOVRI vs 0% placebo), abnormal dreams (2% GOCOVRI vs 1% placebo), dysphagia (2% GOCOVRI vs 0% placebo), and gait disturbance (2% GOCOVRI vs 0% placebo).

Pooled Analysis of Adverse Reactions Reported for ≥3% of Patients Treated With GOCOVRI 274 mg (n=100) or placebo (n=98), respectively: Psychiatric disorders: visual and/or auditory hallucination (21%, 3%); anxiety and/or generalized anxiety (7%, 3%); insomnia (7%, 2%); depression/depressed mood (6%, 1%); abnormal dreams (4%, 2%); confusional state (3%, 2%) Nervous system disorders: dizziness (16%, 1%); headache (6%, 4%); dystonia (3%, 1%) Gastrointestinal disorders: dry mouth (16%, 1%); constipation (13%, 3%); nausea (8%, 3%); vomiting (3%, 0%) General disorders and administration-site conditions: peripheral edema (16%, 1%); gait disturbance (3%, 0%) Injury, poisoning, and procedural complications: fall (13%, 7%); contusion (6%, 1%) Infections and infestations: urinary tract infection (10%, 5%) Skin and subcutaneous tissue disorders: livedo reticularis (6%, 0%); pigmentation disorder (3%, 0%) Metabolism and nutrition disorders: decreased appetite (6%, 1%) Vascular disorders: orthostatic hypotension, including postural dizziness, syncope, presyncope,

HELP YOUR ADULT PATIENTS WITH NMOSD

BE

UP FOR AND MAKING IT THEIRS

UPLIZNA

®

(inebilizumab-cdon) is the first and only FDA-approved B-celldepleting therapy for

NMOSD1

For the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adult patients who are anti-aquaporin-4 (AQP4) antibody positive.

IMPORTANT SAFETY INFORMATION Uplizna® (inebilizumab-cdon) is contraindicated in patients with: • A history of life-threatening infusion reaction to Uplizna

• Active hepatitis B infection

• Active or untreated latent tuberculosis

Warnings and Precautions Infusion Reactions: Uplizna can cause infusion reactions, which can include headache, nausea, somnolence, dyspnea, fever, myalgia, rash, or other symptoms. Infusion reactions were most common with the first infusion but were also observed during subsequent infusions. Administer pre-medication with a corticosteroid, an antihistamine, and an anti-pyretic.

Infections: The most common infections reported by Uplizna-treated patients in the randomized and open-label periods included urinary tract infection (20%), nasopharyngitis (13%), upper respiratory tract infection (8%), and influenza (7%). Delay Uplizna administration in patients with an active infection until the infection is resolved.

Increased immunosuppressive effects are possible if combining Uplizna with another immunosuppressive therapy.

The risk of hepatitis B virus (HBV) reactivation has been observed with other B-cell-depleting antibodies. Perform HBV screening in all patients before initiation of treatment with Uplizna. Do not administer to patients with active hepatitis.

IMPORTANT SAFETY INFORMATION

Warnings and Precautions (continued)

Although no confirmed cases of Progressive Multifocal Leukoencephalopathy (PML) were identified in Uplizna clinical trials, JC virus infection resulting in PML has been observed in patients treated with other B-cell-depleting antibodies and other therapies that affect immune competence. At the first sign or symptom suggestive of PML, withhold Uplizna and perform an appropriate diagnostic evaluation.

Patients should be evaluated for tuberculosis risk factors and tested for latent infection prior to initiating Uplizna.

Vaccination with live-attenuated or live vaccines is not recommended during treatment and after discontinuation, until B-cell repletion.

Reduction in Immunoglobulins: There may be a progressive and prolonged hypogammaglobulinemia or decline in the levels of total and individual immunoglobulins such as immunoglobulins G and M (IgG and IgM) with continued Uplizna treatment. Monitor the level of immunoglobulins at the beginning, during, and after discontinuation of treatment with Uplizna until B-cell repletion especially in patients with opportunistic or recurrent infections.

Fetal Risk: May cause fetal harm based on animal data. Advise females of reproductive potential of the potential risk to a fetus and to use an effective method of contraception during treatment and for 6 months after stopping Uplizna.

Adverse Reactions: The most common adverse reactions (at least 10% of patients treated with Uplizna and greater than placebo) were urinary tract infection and arthralgia.

Brief Summary of Important Information about UPLIZNA® (up-liz’-nah) (inebilizumab-cdon) injection, for intravenous use Indication: Uplizna is a CD19-directed cytolytic antibody indicated for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adult patients who are anti-aquaporin-4 (AQP4) antibody positive.

Contraindications: Uplizna® (inebilizumab-cdon) is contraindicated in patients with: • Previous life-threatening reaction to infusion of Uplizna • Active hepatitis B infection • Active or untreated latent tuberculosis Warnings and precautions: Infusion Reactions Uplizna can cause infusion reactions, which can include headache, nausea, somnolence, dyspnea, fever, myalgia, rash, or other signs or symptoms.

During the randomized clinical trial period, infusion reactions were observed with the first course of Uplizna in 9.3% of NMOSD patients.

Infusion reactions were most common with the first infusion but were also observed during subsequent infusions.

Reducing the Risk of Infusion Reactions and Managing Infusion Reactions: Administer pre-medication with a corticosteroid, an antihistamine, and an anti-pyretic.

Management recommendations for infusion reactions depend on the type and severity of the reaction. For life-threatening infusion reactions, immediately and permanently stop Uplizna and administer appropriate supportive treatment. For less severe infusion reactions, management may involve temporarily stopping the infusion, reducing the infusion rate, and/or administering symptomatic treatment.

Infections An increased risk of infections has been observed with other B-cell-depleting therapies. The most common infections reported by Uplizna-treated patients in the randomized and open-label clinical trial periods included urinary tract infection (20%), nasopharyngitis (13%), upper respiratory tract infection (8%), and influenza (7%). Delay Uplizna administration in patients with an active infection until the infection is resolved.

Possible Increased Risk of Immunosuppressant Effects with Other Immunosuppressants: Uplizna has not been studied in combination with other immunosuppressants. If combining Uplizna with another immunosuppressive therapy, consider the potential for increased immunosuppressive effects.

Hepatitis B Virus (HBV) Reactivation: Risk of HBV reactivation has been observed with

other B-cell-depleting antibodies. There have been no cases of HBV reactivation in patients treated with Uplizna, but patients with chronic HBV infection were excluded from clinical trials. Perform HBV screening in all patients before initiation of treatment with Uplizna. Do not administer Uplizna to patients with active hepatitis. For patients who are chronic carriers of HBV [HBsAg+], consult liver disease experts before starting and during treatment.

Progressive Multifocal Leukoencephalopathy (PML): PML is an opportunistic viral infection of the brain caused by the JC virus that typically only occurs in patients who are immunocompromised, and that usually leads to death or severe disability. Although no confirmed cases of PML were identified in Uplizna clinical trials, JC virus infection resulting in PML has been observed in patients treated with other B-cell-depleting antibodies and other therapies that affect immune competence. In Uplizna clinical trials one subject died following the development of new brain lesions for which a definitive diagnosis could not be established, though the differential diagnosis included an atypical NMOSD relapse, PML, or acute disseminated encephalomyelitis. At the first sign or symptom suggestive of PML, withhold Uplizna and perform an appropriate diagnostic evaluation.

MRI findings may be apparent before clinical signs or symptoms. 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.

Tuberculosis: Patients should be evaluated for tuberculosis risk factors and tested for latent infection prior to initiating Uplizna. Consider anti-tuberculosis therapy prior to initiation of Uplizna in patients with a history of latent active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent tuberculosis but having risk factors for tuberculosis infection.

Consult infectious disease experts regarding whether initiating anti-tuberculosis therapy is appropriate before starting treatment.

Vaccinations: Administer all immunizations according to immunization guidelines at least 4 weeks prior to initiation of Uplizna. The safety of immunization with live or live-attenuated vaccines following Uplizna therapy has not been studied, and vaccination with live-attenuated or live vaccines is not recommended during treatment and until B-cell repletion.

Vaccination of Infants Born to Mothers Treated with Uplizna During Pregnancy: In infants of mothers exposed to Uplizna during pregnancy, do not administer live or live-attenuated vaccines before confirming recovery of B-cell counts in the infant. Depletion of B-cells in these exposed infants may increase the risks from live

or live-attenuated vaccines. Non-live vaccines, as indicated, may be administered prior to recovery from B-cell and immunoglobulin level depletion, but consultation with a qualified specialist should be considered to assess whether a protective immune response was mounted.

Reduction in Immunoglobulins There may be a progressive and prolonged hypogammaglobulinemia or decline in the levels of total and individual immunoglobulins such as immunoglobulins G and M (IgG and IgM) with continued Uplizna treatment. Monitor the levels of quantitative serum immunoglobulins during treatment with Uplizna, especially in patients with opportunistic or recurrent infections, and until B-cell repletion after discontinuation of therapy.

Consider discontinuing Uplizna therapy if a patient with low immunoglobulin G or M develops a serious opportunistic infection or recurrent infections, or if prolonged hypogammaglobulinemia requires treatment with intravenous immunoglobulins.

Fetal Risk Based on animal data, Uplizna can cause fetal harm due to B-cell lymphopenia and reduce antibody response in offspring exposed to Uplizna even after B-cell repletion. Transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other B-cell depleting antibodies during pregnancy. Advise females of reproductive potential to use effective contraception while receiving Uplizna and for at least 6 months after the last dose.

Adverse Reactions The safety of Uplizna was evaluated in Study 1, in which 161 patients were exposed to Uplizna at the recommended dosage regimen during the randomized, controlled treatment period; during which 52 patients received placebo.

Subsequently, 198 patients were exposed to Uplizna during an open-label treatment period.

Two-hundred and eight patients in the randomized and open-label treatment periods had a total of 324 person-years of exposure to Uplizna, including 165 patients with exposure for at least 6 months and 128 with exposure for one year or more.

The most common adverse reactions (at least 10% of patients treated with Uplizna and greater than placebo) were urinary tract infection and arthralgia. Adverse reactions in patients with NMOSD with an incidence of at least 5% with Uplizna and a greater incidence than placebo included urinary tract infection (11% vs 10%), arthralgia (10% vs 4%), headache (8% in both arms) and back pain (7% vs 4%).

Across both the randomized and open-label treatment, the most common adverse reactions (greater than 10%) were urinary tract infection (20%), nasopharyngitis (13%), infusion reaction (12%), arthralgia (11%), and headache (10%).

Laboratory Abnormalities Decreased Immunoglobulins: At the end of the 6.5-month randomized, controlled period, relative to baseline, the total immunoglobulin level was reduced approximately 8% from baseline for patients treated with Uplizna as compared to an increase of 6% in patients treated with placebo. The mean decreases from baseline in immunoglobulin G (IgG) and immunoglobulin M (IgM) were approximately 4% and 32%, respectively, in patients treated with Uplizna, whereas IgG was increased by 6% and IgM was increased by approximately 13% in placebo-treated patients.

The proportion of patients treated with Uplizna who had IgG levels below the lower limit of normal at year 1 was 6.6% and at year 2 was 13%. The proportion of patients treated with Uplizna who had IgM levels below the lower limit of normal at year 1 was 31% and at year 2 was 42%.

Decreased Neutrophil Counts: Neutrophil counts between 1.0-1.5 x10 9/L were observed in 6.9% of Uplizna-treated patients versus 1.9% of patients who received placebo. Neutrophil counts between 0.5-1.0 x10 9/L were observed in 1.9% of patients treated with Uplizna compared to no patients who received placebo. At the end of the 6.5-month randomized, controlled period, the proportion of patients with a neutrophil count below the limit of normal was 12% for patients treated with Uplizna compared to 4.2% for patients who received placebo.

Decreased Lymphocyte Counts: A reduction in lymphocyte counts was observed more frequently in patients treated with Uplizna compared to those who received placebo. At the end of the 6.5-month randomized, controlled period, the proportion of patients with a lymphocyte count below the limit of normal was 5.3% for patients treated with Uplizna compared to 4.2% for patients who received placebo.

Immunogenicity As with all therapeutic proteins there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease.

For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other inebilizumab products may be misleading.

In Study 1, treatment-emergent antibodies (those that appeared or significantly increased from baseline after administration of Uplizna), were detected in 5.6% of patients receiving Uplizna. Although these data do not demonstrate an impact of anti-inebilizumab-cdon antibody development on the efficacy or safety of Uplizna in these patients, the available data are too limited to make definitive conclusions.

Drug interactions: Concomitant usage of Uplizna with immunosuppressant drugs, including systemic corticosteroids, may increase the risk of infection.

Consider the risk of additive immune system effects when co-administering immunosuppressive therapies with Uplizna.

Use in specific populations: Pregnancy Uplizna is a humanized IgG1 monoclonal antibody and immunoglobulins are known to cross the placental barrier. There are no adequate data on the developmental risk associated with the use of Uplizna in pregnant women. However, transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other B-cell depleting antibodies during pregnancy. B-cell levels in infants following maternal exposure to Uplizna have not been studied in clinical trials. The potential duration of B-cell depletion in such infants, and the impact of B-cell depletion on vaccine safety and effectiveness, is unknown.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Animal Data: Intravenous administration of inebilizumab-cdon (0, 3, or 30 mg/kg/week) to human CD19 transgenic (huCD19 Tg) male and female mice prior to and during mating and continuing in females through gestation day 15 resulted in no adverse effects on embryofetal development; however, there was a marked reduction in B cells in fetal blood and liver at both doses tested. These results demonstrate that inebilizumab-cdon crosses the placenta and depletes B cells in the fetus.

Intravenous administration of inebilizumab-cdon (0, 3, or 30 mg/kg) to huCD19 Tg mice every three days throughout organogenesis and lactation resulted in depletion of B cells and persistent reductions in immune function (even following repletion of B cells and lasting into adulthood) in offspring at both doses tested. At the end of the lactation period, plasma inebilizumab-cdon levels in offspring were only slightly lower than those in maternal plasma. A no-effect level for immunotoxicity in the offspring was not identified.

Lactation There are no data on the presence of inebilizumabcdon in human milk, the effects on a breastfed infant, or the effects on milk production. Human IgG is excreted in human milk, and the potential for absorption of Uplizna to lead to B-cell depletion in the breastfed infant is unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Uplizna and any potential adverse effects on the breastfed infant from Uplizna or from the underlying maternal condition.

Females of Reproductive Potential Women of childbearing potential should use contraception while receiving Uplizna and for 6 months after the last infusion of Uplizna.

Pediatric Use Safety and effectiveness in pediatric patients have not been established.

Geriatric Use Clinical studies of Uplizna did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.
