Kisunla

2 DOSAGE AND ADMINISTRATION Confirm the presence of amyloid beta pathology prior to initiating treatment. ( 2.1 ) Administer KISUNLA as an intravenous infusion over approximately 30 minutes every four weeks as follows ( 2.2 ): Infusion 1: 350 mg Infusion 2: 700 mg Infusion 3: 1,050 mg Infusion 4 and beyond: 1,400 mg Consider stopping dosing with KISUNLA based on reduction of amyloid plaques to minimal levels on amyloid PET imaging. ( 2.2 ) Obtain a recent baseline brain MRI prior to initiating treatment. ( 2.3 , 5.1 ) Obtain an MRI prior to the 2nd, 3rd, 4th, and 7th infusions. If radiographically observed ARIA occurs, treatment recommendations are based on type, severity, and presence of symptoms. ( 2.3 , 5.1 ) Dilution to a final concentration of 4 mg/mL to 10 mg/mL with 0.9% Sodium Chloride Injection, is required prior to administration. ( 2.4 ) 2.1 Patient Selection Confirm the presence of amyloid beta pathology prior to initiating treatment [see Clinical Pharmacology ( 12.1 )] . 2.2 Dosing Instructions Administer KISUNLA every four weeks as an intravenous infusion over approximately 30 minutes with the recommended dosage and dosing schedule described in Table 1 . KISUNLA must be diluted prior to administration ( see Table 4 ). Table 1: Recommended Dosage* and Dosing Schedule *Dosing Regimen 2 [see Warnings and Precautions ( 5.1 ) and Clinical Studies ( 14 )] Intravenous Infusion (every 4 weeks) KISUNLA Dosage (administered over approximately 30 minutes) Infusion 1 350 mg Infusion 2 700 mg Infusion 3 1,050 mg Infusion 4 and beyond 1,400 mg Consider stopping dosing with KISUNLA based on reduction of amyloid plaques to minimal levels on amyloid PET imaging. In Study 1 and Study 2, dosing was stopped based on a reduction of amyloid levels below predefined thresholds on PET imaging [see Clinical Studies ( 14 )] . If an infusion is missed, resume administration every 4 weeks at the same dose as soon as possible. 2.3 Monitoring and Dosing Interruption for Amyloid Related Imaging Abnormalities KISUNLA can cause amyloid related imaging abnormalities -edema (ARIA-E) and -hemosiderin deposition (ARIA-H) [see Warnings and Precautions ( 5.1 ) and Adverse Reactions ( 6.1 )] . Monitoring for ARIA Obtain a recent baseline brain magnetic resonance imaging (MRI) prior to initiating treatment with KISUNLA. Obtain an MRI prior to the 2 nd , 3 rd , 4 th , and 7 th infusions. If a patient experiences symptoms suggestive of ARIA, clinical evaluation should be performed, including an MRI if indicated. Recommendations for Dosing Interruptions in Patients with ARIA ARIA-E The recommendations for dosing interruptions for patients with ARIA-E are provided in Table 2 . Table 2: Dosing Recommendations for Patients With ARIA-E c a Mild: discomfort noticed, but no disruption of normal daily activity. Moderate: discomfort sufficient to reduce or affect normal daily activity. Severe: incapacitating, with inability to work or to perform normal daily activity. b Suspend until MRI demonstrates radiographic resolution and symptoms, if present, resolve; consider a follow-up MRI to assess for resolution 2 to 4 months after initial identification. Resumption of dosing should be guided by clinical judgment. c See Table 5 for MRI radiographic severity [Warning and Precautions ( 5.1 )] . Clinical Symptom Severity a ARIA-E Severity on MRI Mild Moderate Severe Asymptomatic May continue dosing at current dose and schedule Suspend dosing b Suspend dosing b Mild May continue dosing based on clinical judgment Suspend dosing b Moderate or Severe Suspend dosing b ARIA-H The recommendations for dosing interruptions for patients with ARIA-H are provided in Table 3 . Table 3: Dosing Recommendations for Patients With ARIA-H c a Suspend until MRI demonstrates radiographic stabilization and symptoms, if present, resolve; resumption of dosing should be guided by clinical judgment; consider a follow-up MRI to assess for stabilization 2 to 4 months after initial identification. b Suspend until MRI demonstrates radiographic stabilization and symptoms, if present, resolve. Use clinical judgment when considering whether to continue treatment or permanently discontinue KISUNLA. c See Table 5 for MRI radiographic severity [Warning and Precautions ( 5.1 )] . Clinical Symptom Severity ARIA-H Severity on MRI Mild Moderate Severe Asymptomatic May continue dosing at current dose and schedule Suspend dosing a Suspend dosing b Symptomatic Suspend dosing a Suspend dosing a In patients who develop intracerebral hemorrhage greater than 1 cm in diameter during treatment with KISUNLA, suspend dosing until MRI demonstrates radiographic stabilization and symptoms, if present, resolve. Use clinical judgment when considering whether to continue treatment or permanently discontinue KISUNLA after radiographic stabilization and resolution of symptoms. 2.4 Dilution Instructions Prior to administration, KISUNLA must be diluted with 0.9% sodium chloride injection ( see Table 4 ). Use aseptic technique when preparing the diluted KISUNLA solution for intravenous infusion. Allow KISUNLA to equilibrate to room temperature before preparation. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. KISUNLA solution is clear to opalescent, colorless to slightly yellow to slightly brown. Do not use if particulate matter or discolorations are present. Withdraw required volume of KISUNLA and mix with 0.9% sodium chloride injection, to the recommended total volume for a final concentration of 4 mg/mL to 10 mg/mL ( see Table 4 ). Use only 0.9% sodium chloride injection for dilution.

Discard any unused portion left in the vial. Gently invert the diluted KISUNLA solution to mix completely. Do not shake. After dilution, immediate use is recommended [see Description ( 11 )] . If the diluted KISUNLA solution is not administered immediately, store refrigerated at 2°C to 8°C (36°F to 46°F) for up to 72 hours or at room temperature (20°C to 25°C [68°F to 77°F]) for up to 12 hours. Do not freeze the diluted KISUNLA solution. Storage times include the duration of infusion. 2.5 Administration Instructions Visually inspect the diluted KISUNLA solution for particles or discoloration prior to administration. Do not use if it is discolored, or opaque or foreign particles are seen. Prior to infusion, if the diluted solution has been stored under refrigeration, allow the diluted KISUNLA solution to warm to room temperature. Administer the entire diluted solution intravenously over approximately 30 minutes. Flush the line only with 0.9% sodium chloride injection at the end of the infusion per access specific line maintenance protocol. Observe the patient post-infusion for a minimum of 30 minutes, and consider longer periods of observation if clinically indicated, to evaluate for infusion reactions and hypersensitivity reactions. The infusion rate may be reduced, or the infusion may be discontinued, and appropriate therapy administered as clinically indicated. Consider pre-medication at subsequent dosing with antihistamines, non-steroidal anti-inflammatory drugs, or corticosteroids [see Warnings and Precautions ( 5.2 )] .
