DAXXIFY

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Spread of Effects from Toxin [see Warnings and Precautions (5) ] Hypersensitivity Reactions [see Warnings and Precautions (5.6) ] Dysphagia and Breathing Difficulties [see Warnings and Precautions (5.6) ] The most commonly observed adverse reactions (≥1%) are headache (6%), eyelid ptosis (2%) and facial paresis (1%). ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Revance Therapeutics, Inc. at 1-877-373-8669 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trial 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. The most common side effects from treatment with DAXXIFY usually occur within one to two weeks after injection and while generally transient, may have a duration of several weeks or months. Glabellar Lines In the two randomized, placebo-controlled, Phase 3 clinical trials that assess the use of DAXXIFY for the temporary improvement in the appearance of moderate to severe glabellar lines, GL-1 and GL-2, 406 subjects received a single dose treatment of 40 Units DAXXIFY and 203 subjects received placebo. The most frequent adverse reactions are presented in Table 3. TABLE 3: Most Common Adverse Reactions ≥1% and More Frequent than Placebo in Pooled Double-Blind, Placebo-Controlled Trials for Glabellar Lines Adverse Reaction DAXXIFY N=406 n (%) Placebo N=203 n (%) Headache 26 (6%) 4 (2%) Eyelid ptosis 9 (2%) 0 (0%) Facial paresis Facial paresis, including facial asymmetry. 5 (1%) 0 (0%) Injection site reactions were reported in 6% of subjects treated with DAXXIFY and in 6% of subjects treated with placebo (these reactions included injection site pain, injection site erythema, injection site oedema, injection site bruising, injection site hematoma, injection site papule, injection site pruritus). In an 84-week open label repeat-dose safety study in glabellar lines, 2691 subjects were treated with 40 U of DAXXIFY. Of these, 2380 subjects received one treatment with DAXXIFY, 882 received two treatments with DAXXIFY and 568 subjects received three treatments with DAXXIFY. Adverse reactions were reported in 535 of the 2691 subjects (20%). The adverse reaction profile was similar to that reported in single dose trials. Injection site reactions were the most common adverse reactions, reported in 9% of subjects [including injection site pain (4%) , injection site erythema (3%), injection site oedema (3%), injection site bruising (1%), injection site papule (<1%), injection site pruritus (<1%)], followed by headache (5%), edema (2%), erythema (2%) and eyelid ptosis in 1% of subjects. The incidence of these adverse reactions did not increase with multiple re-treatments. 6.2 Immunogenicity As with all therapeutic proteins, there is a 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 products can be misleading. Treatment with botulinum toxins may result in the formation of antibodies that may reduce the effectiveness of subsequent treatments by inactivating biological activity of the toxin. Among 2786 subjects receiving up to 3 treatments with DAXXIFY in the phase 3 studies, 12 Subjects (0.4%) had preexisting binding antibodies to daxibotulinumtoxinA-lanm and 75 (3%) had preexisting binding antibodies to the 35 amino acid peptide excipient RTP004. A total of 20 (0.8%) subjects developed treatment-emergent binding antibodies to daxibotulinumtoxinA-lanm and 33 (1.2%) subjects developed treatment-emergent binding antibodies to RTP004. No subjects developed neutralizing antibodies to DAXXIFY.

4 CONTRAINDICATIONS Known hypersensitivity to any botulinum toxin preparation, DAXXIFY or any of the components in the DAXXIFY formulation ( 4.1 ) Infection at the injection sites ( 4.2 ) 4.1 Hypersensitivity DAXXIFY is contraindicated in patients with known hypersensitivity to any botulinum toxin preparation, DAXXIFY or any of the components in the DAXXIFY formulation. 4.2 Infection at Injection Site DAXXIFY is contraindicated in the presence of infection at the proposed injection sites.

11 DESCRIPTION DaxibotulinumtoxinA-lanm is an acetylcholine release inhibitor and neuromuscular blocking agent. DaxibotulinumtoxinA-lanm is a 150 kDa botulinum toxin without accessory proteins purified from the bacterium Clostridium botulinum type A. DAXXIFY (daxibotulinumtoxinA-lanm) for injection is supplied as a sterile, preservative-free, white to off-white lyophilized powder in a single-dose vial for intramuscular use after reconstitution. DAXXIFY is formulated with a 35 amino acid peptide excipient (RTP004) that prevents surface adsorption and promotes thermal stability of DAXXIFY. Each vial contains 50 Units or 100 Units of daxibotulinumtoxinA-lanm, L-histidine (0.14 mg), L-histidine-HCl monohydrate (0.65 mg), polysorbate 20 (0.1 mg), RTP004 peptide (11.7 mcg), and trehalose dihydrate (36 mg).

2 DOSAGE AND ADMINISTRATION Glabellar Lines: 0.1 mL (8 Units) by intramuscular injection into each of five sites, for a total dose of 40 Units. ( 2 ) 2.1 Important Administration Instructions The potency units of DAXXIFY for injection are specific to the preparation and test method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of DAXXIFY cannot be compared to or converted into units of any other botulinum toxin products assessed with any other specific test method. [see Warnings and Precautions (5.12), Description (11) ] The safe and effective use of DAXXIFY depends upon proper storage of the product, selection of the correct dose, and proper reconstitution and administration techniques. Glabellar lines arise from the contraction of the corrugator and procerus muscles. These can be identified by palpation of the glabellar muscle mass while having the patient frown maximally. Contraction of the corrugator muscles compresses the skin, creating a vertical line or lines surrounded by ridges of tensed muscle. Because the exact location, size, and activity of the muscles can vary markedly among individuals, physicians administering DAXXIFY must understand the relevant anatomy of the area involved and any alterations to the anatomy due to prior surgical procedures and diseases [see Warnings and Precautions (5.8) ] . After assessment, the location of the corrugator muscle injection sites may need to be adjusted based on individual facial anatomy and the pattern of muscle contraction. DAXXIFY should be administered no more frequently than every three months. Consideration of the cumulative dose is necessary when treating adult patients with DAXXIFY. Physicians should be aware of whether patients are receiving treatment with other botulinum toxin products for other indications. Reconstituted DAXXIFY is intended for intramuscular injection only. Reconstitution instructions are provided specifically for the 50 Unit and the 100 Unit vials (Table 1; Table 2). 2.2 Recommended Dosage The total recommended dose is 40 Units per treatment session divided into five equal intramuscular injections of 8 Units each (two injections in each corrugator muscle and one injection in the procerus muscle). 2.3 Preparation and Dilution Technique DAXXIFY is supplied in single-dose 50 Unit and 100 Unit vials. Prior to intramuscular injection, reconstitute each vial of DAXXIFY with the required amount of sterile, preservative-free 0.9% Sodium Chloride Injection, USP to obtain a reconstituted solution at a concentration of 8 Units/0.1 mL (see Tables 1 and 2 ). Table 1: DAXXIFY 50 Unit Vials Dilution Volume for Reconstitution Diluent Preservative-free 0.9% Sodium Chloride Injection, USP Added to 50 Unit Vial Resulting dose in Units per 0.1 mL 0.6 mL 8 Units Table 2: DAXXIFY 100 Unit Vials Dilution Volume for Reconstitution Diluent Preservative-free 0.9% Sodium Chloride Injection, USP Added to 100 Unit Vials Resulting dose in Units per 0.1 mL 1.2 mL 8 Units Slowly inject the diluent into the vial. Discard the vial if a vacuum does not pull the diluent into the vial. Dispose of any unused diluent. Gently mix DAXXIFY with 0.9% Sodium Chloride Injection, USP by rotating the vial. Reconstituted DAXXIFY solution is clear to slightly opalescent and colorless and free of particulate matter. Inspect visually the reconstituted DAXXIFY for particulate matter and discoloration prior to administration. Do not use if the solution is cloudy or discolored or contains flakes or particles. Administer DAXXIFY within 72 hours after reconstitution. During this time period, store unused reconstituted DAXXIFY in a refrigerator between 2°C to 8°C (36°F to 46°F) and protected from light. Do not freeze reconstituted DAXXIFY. Dispose of any unused DAXXIFY. 2.4 Administration After reconstitution, only use each DAXXIFY vial for only one injection session and for only one patient. Discard any remaining solution in vial immediately after administration. The upper eyelid margin position should be carefully examined for separation or weakness of the levator palpebrae superioris muscle. Evaluate the range of upper eyelid excursion while manually immobilizing the frontalis to assess degree of levator function and frontalis compensation. In order to reduce the complication of ptosis, the following steps should be taken: Avoid injection near the levator palpebrae superioris, particularly in patients with larger brow depressor complexes. Ensure the injected volume/dose is accurate and administer in a steady, controlled manner. Do not inject DAXXIFY less than 1 centimeter above the superior orbital rim. To inject DAXXIFY, clean the exposed portion of the stopper with an alcohol swab and aseptically withdraw at least 0.5 mL of the reconstituted solution from the vial into a sterile syringe. Replace the needle used to withdraw the product with a 30 to 33 gauge sterile needle for injection. Expel any air bubbles prior to administration. Advance the needle through the skin into the underlying muscle while applying finger pressure on the superior medial orbital rim. Inject a dose of 8 Units (0.1 mL) into each of the 5 injection sites: 2 injections into medial corrugator and lateral corrugator muscles respectively, and 1 injection in the procerus muscle (Figure 1). FIGURE 1: INJECTION SITES FOR GLABELLAR LINES Figure 1

1 INDICATIONS AND USAGE DAXXIFY (daxibotulinumtoxinA-lanm) is indicated for the temporary improvement in the appearance of moderate to severe glabellar lines associated with corrugator and/or procerus muscle activity in adult patients. DAXXIFY is an acetylcholine release inhibitor and neuromuscular blocking agent indicated for the temporary improvement in the appearance of moderate to severe glabellar lines associated with corrugator and/or procerus muscle activity in adult patients. ( 1 )

10 OVERDOSAGE Excessive doses of DAXXIFY may be expected to produce neuromuscular weakness with a variety of symptoms. Respiratory support may be required where excessive doses cause paralysis of the respiratory muscles. In the event of overdose, the patient should be medically monitored for symptoms or excessive muscle weakness or muscle paralysis. [see Warnings and Precautions (5.6) , (5.7) ] Symptomatic treatment may be necessary. Symptoms of overdose are not likely to be present immediately following injection. Should accidental injection or oral ingestion occur, the person should be medically supervised for several weeks for signs and symptoms of excessive muscle weakness or paralysis. In the event of overdose, antitoxin raised against botulinum toxin is available from the Centers for Disease Control and Prevention (CDC) in Atlanta, GA. However, the antitoxin will not reverse any botulinum toxin-induced effects already apparent by the time of antitoxin administration. In the event of suspected or actual cases of botulinum toxin poisoning, please contact your local or state Health Department to process a request for antitoxin through the CDC. If you do not receive a response within 30 minutes, please contact the CDC directly at 1-770-488-7100.

7 DRUG INTERACTIONS No formal drug interaction studies have been conducted with DAXXIFY. However, the potential for certain drugs to potentiate the effects of DAXXIFY warrant consideration given the potential risks involved and should be used with caution. Aminoglycosides or other agents interfering with neuromuscular transmission Anticholinergic drugs Botulinum neurotoxin products Muscle relaxants Aminoglycoside antibiotics, anticholinergic agents or any other agents that interfere with neuromuscular transmission may potentiate the effect of DAXXIFY; co-administer only with caution and close observation. ( 7 )

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action DAXXIFY blocks cholinergic transmission at the neuromuscular junction by inhibiting the release of acetylcholine. When injected into skeletal muscle, DAXXIFY is internalized into the nerve terminal, translocates into the neuronal cytosol where it cleaves SNAP25, a protein necessary for synaptic vesicle membrane docking and subsequent release of acetylcholine which produces a dose dependent decrease of muscle function. Recovery of activity is gradual and results from the degradation of neurotoxin light chain in the neurons with a contribution from the formation of axonal sprouts. Muscle reinnervation occurs, leading to a slow reversal of the pharmacological effects of DAXXIFY. 12.2 Pharmacodynamics No formal pharmacodynamics studies have been conducted with DAXXIFY. 12.3 Pharmacokinetics Using currently available analytical technology, it is not possible to detect DAXXIFY in the peripheral blood following intramuscular injection at the recommended dose.

This Medication Guide has been approved by the U.S. Food and Drug Administration Issued: 9/2022 MEDICATION GUIDE DAXXIFY™ (dax'-i-fye) daxibotulinumtoxinA-lanm for injection, for intramuscular use What is the most important information I should know about DAXXIFY? DAXXIFY may cause serious side effects that can be life threatening. Call your healthcare provider or get medical help right away if you have any of these problems after treatment with DAXXIFY: Problems swallowing, speaking, or breathing. These problems can happen hours, days, or weeks after an injection of DAXXIFY if the muscles that you use to breathe and swallow become weak after the injection. Death can happen as a complication if you have severe problems with swallowing or breathing after treatment with DAXXIFY. People with certain breathing problems may need to use muscles in their neck to help them breathe. These people may be at greater risk for serious breathing problems with DAXXIFY. Swallowing problems may last for several months. People who cannot swallow well may need a feeding tube to receive food and water. If swallowing problems are severe, food or liquids may go into your lungs. People who already have swallowing or breathing problems before receiving DAXXIFY have the highest risk of getting these problems. Spread of toxin effects . In some cases, the effect of botulinum toxin may affect areas of the body away from the injection site and cause symptoms of a serious condition called botulism. The symptoms of botulism include: loss of strength and muscle weakness all over the body blurred vision and drooping eyelids trouble saying words clearly trouble breathing double vision hoarseness or change or loss of voice loss of bladder control trouble swallowing These symptoms can happen hours, days, or weeks after you receive an injection of DAXXIFY. These problems could make it unsafe for you to drive a car or do other dangerous activities. See " What should I avoid while receiving DAXXIFY? " Although no serious adverse reactions of distant spread of toxin effect associated with DAXXIFY have been reported in clinical studies of 40 Units for glabellar lines, these reactions are possible.

14 CLINICAL STUDIES 14.1 Glabellar Lines Two randomized, double-blind, multi-center, placebo-controlled clinical trials, Studies GL-1 and GL-2, were conducted to evaluate DAXXIFY for use in the temporary improvement of moderate-to-severe glabellar lines in adults. The 2 trials enrolled a total of 609 subjects (≥18 years old) with glabellar lines of at least moderate severity at maximum frown. A total of 405 subjects were randomized and 406 were treated with 40 Units of DAXXIFY and 204 subjects were randomized and 203 were treated with an equal volume of placebo. Subjects were excluded if they had eyelid ptosis, deep dermal scarring, excessive dermatochalasis or an inability to lessen glabellar lines by physically spreading them apart. Enrolled subjects were 21 to 75 years old, with a mean age of 50 years, were predominantly female (87%) and Caucasian (86%). The total dose was delivered in 5 equally divided intramuscular injections of 8 Units each to specific sites in the glabellar (Figure 1). Subjects were followed for at least 24 weeks after treatment. Efficacy was determined through the assessment by investigators and subjects of frown wrinkle severity at maximum frown using a 4-point scale (0 = none, 1 = mild, 2 = moderate, 3 = severe). The primary efficacy endpoint (treatment success) was defined as achieving a score of 0 or 1 (none or mild) and an improvement of at least 2 points from baseline for both the investigator's and subject's assessments at Week 4. The percentages of subjects with treatment success at Week 4 are presented in Table 4.

Subjects were followed through at least Week 24 and then were discontinued from the study when both the investigator and subject scores returned to baseline. Subjects who returned to baseline levels prior to Week 36 were counted as non-responders following study discontinuation. FIGURE 2: Proportion of subjects rated as 0 or 1 (none or mild) by investigator, 0 or 1 by the subject, and 0 or 1 with at least 2-point improvement from their baseline (based on both the investigator and subject ratings) in Study GL-1 and Study GL-2. Treatment Success is defined as a score of 0 or 1 (none or mild) and ≥ 2-grade improvement from baseline on both the investigator and subject assessment. Figure 2 - Study GL-1 Figure 2 - Study GL-2

8.5 Geriatric Use Among the 406 subjects treated with DAXXIFY in the placebo-controlled clinical trials, 36 subjects were 65 years or older. There was no increase in the incidence of treatment-related adverse events in patients over 65 years treated with DAXXIFY. Clinical studies of DAXXIFY did not include sufficient numbers of subjects aged 65 and older to determine whether they responded differently from younger subjects. [see Clinical Studies (14) ]

8.4 Pediatric Use Safety and effectiveness of DAXXIFY in patients less than 18 years of age have not been established.

8.1 Pregnancy Risk Summary There are no available data on DAXXIFY use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, intramuscular administration of DAXXIFY during pregnancy resulted in adverse effects on fetal growth (decreased fetal body weight and skeletal ossification) at maternally toxic doses approximately equivalent to 40 times the maximum recommended human dose (MRHD) ( see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data Embryofetal development studies were conducted in rats and rabbits with DAXXIFY. For comparison of animal to human doses based on a body weight comparison, the MRHD is set at 40 Units/subject (0.67 Units/kg for an average 60 kg subject). Intramuscular administration of DAXXIFY (3, 10 or 30 Units/kg) to pregnant rats four times during the period of organogenesis (on gestation days 7, 10, 13, and 16) caused decreased fetal body weight and decreased fetal skeletal ossification at the highest dose, which was associated with maternal toxicity. No embryofetal developmental toxicity was noted at doses up to 10 Units/kg which is 15 times the MRHD. Intramuscular administration of DAXXIFY (0.02, 0.1, 0.48 or 2.4 Units/kg/day) to pregnant rabbits during the period of organogenesis (total of 13 doses) resulted in maternal lethality at 2.4 Units/kg/day and significant decreased maternal body weight at 0.48 Units/kg/day. No embryofetal developmental toxicity was noted at doses up to 0.48 Units/kg/day which is approximately equivalent to the MRHD.

No embryofetal developmental toxicity was noted at doses up to 0.48 Units/kg/day which is approximately equivalent to the MRHD. 8.2 Lactation Risk Summary There are no data on the presence of DAXXIFY in human or animal milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for DAXXIFY and any potential adverse effects on the breastfed infant from DAXXIFY or from the underlying maternal condition. 8.4 Pediatric Use Safety and effectiveness of DAXXIFY in patients less than 18 years of age have not been established. 8.5 Geriatric Use Among the 406 subjects treated with DAXXIFY in the placebo-controlled clinical trials, 36 subjects were 65 years or older. There was no increase in the incidence of treatment-related adverse events in patients over 65 years treated with DAXXIFY. Clinical studies of DAXXIFY did not include sufficient numbers of subjects aged 65 and older to determine whether they responded differently from younger subjects. [see Clinical Studies (14) ]
