Ocrevus Zunovo

2 DOSAGE AND ADMINISTRATION OCREVUS ZUNOVO should be administered by a healthcare professional ( 2.1 ) For subcutaneous use in the abdomen only ( 2.1 ) OCREVUS ZUNOVO has different dosage and administration instructions than intravenous ocrelizumab ( 2.1 ) Before initiating OCREVUS ZUNOVO, screen for Hepatitis B virus and obtain serum quantitative immunoglobulins, aminotransferases, alkaline phosphatase, and bilirubin ( 2.2 ) Pre-medicate orally with dexamethasone (or an equivalent corticosteroid) and an antihistamine (e.g., desloratadine) at least 30 minutes prior to each injection ( 2.3 ) Administer 23 mL of OCREVUS ZUNOVO (920 mg ocrelizumab and 23,000 units hyaluronidase) subcutaneously in the abdomen over approximately 10 minutes every 6 months ( 2.4 ) Monitor patients closely during all injections, for at least one hour after the initial injection, and for at least 15 minutes after subsequent injections ( 2.4 ) 2.1 Important Administration Information OCREVUS ZUNOVO is for subcutaneous use in the abdomen only. OCREVUS ZUNOVO has different dosage and administration instructions than intravenous ocrelizumab. OCREVUS ZUNOVO should be administered via subcutaneous injection by a healthcare professional. 2.2 Assessments Prior to First Dose of OCREVUS ZUNOVO Hepatitis B Virus Screening Prior to initiating ocrelizumab treatment, perform Hepatitis B virus (HBV) screening. OCREVUS ZUNOVO is contraindicated in patients with active HBV confirmed by positive results for HBsAg and anti-HBV tests. For patients who are negative for surface antigen [HBsAg] and positive for HB core antibody [HBcAb+] or are carriers of HBV [HBsAg+], consult liver disease experts before starting and during treatment [see Warnings and Precautions (5.2) ] . Serum Immunoglobulins Prior to initiating ocrelizumab treatment, perform testing for quantitative serum immunoglobulins [see Warnings and Precautions (5.4) ] . For patients with low serum immunoglobulins, consult immunology experts before initiating treatment with ocrelizumab. Vaccinations Because vaccination with live-attenuated or live vaccines is not recommended during treatment and after discontinuation until B-cell repletion, administer all immunizations according to immunization guidelines at least 4 weeks prior to initiation of ocrelizumab treatment for live or live-attenuated vaccines and, whenever possible, at least 2 weeks prior to initiation of ocrelizumab treatment for non-live vaccines [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.2) ] . Liver Function Tests Prior to initiating OCREVUS ZUNOVO, obtain serum aminotransferases (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]), alkaline phosphatase, and bilirubin levels [see Warnings and Precautions (5.7) ] . 2.3 Assessments and Premedication Prior to Every Dose Infection Assessment Prior to every dose of OCREVUS ZUNOVO, determine whether there is an active infection. In case of active infection, delay administration of OCREVUS ZUNOVO until the infection resolves [see Warnings and Precautions (5.2) ]. Recommended Premedication Pre-medicate orally with 20 mg of dexamethasone (or an equivalent corticosteroid) and an antihistamine (e.g., desloratadine) administered at least 30 minutes prior to each OCREVUS ZUNOVO administration to reduce the risk of local and systemic injection reactions [see Warnings and Precautions (5.1) ] . The addition of an antipyretic (e.g., acetaminophen) may also be considered. 2.4 Recommended Dosage The recommended dosage of OCREVUS ZUNOVO is 920 mg/23,000 units (920 mg ocrelizumab and 23,000 units of hyaluronidase) administered as a single 23 mL subcutaneous injection in the abdomen over approximately 10 minutes every 6 months. Monitor the patient closely during injections, with access to appropriate medical support to manage severe injection reactions . For the initial dose, monitor the patient for at least one hour post-injection. For subsequent doses, monitor the patient for at least 15 minutes post-injection [see Warnings and Precautions (5.1) ] . 2.5 Delayed or Missed Doses If a planned injection of OCREVUS ZUNOVO is missed, administer OCREVUS ZUNOVO as soon as possible; do not wait until the next scheduled dose. Reset the dose schedule to administer the next sequential dose 6 months after the missed dose is administered. Doses of OCREVUS ZUNOVO must be separated by at least 5 months [see Dosage and Administration (2.4) ]. 2.6 Preparation and Administration To prevent medication errors, check the vial labels to ensure that the drug being prepared and administered is OCREVUS ZUNOVO and not intravenous ocrelizumab. Visually inspect the vial for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use the vial if particulates or discoloration are present. Do not shake. Discard any unused portion remaining in the vial. OCREVUS ZUNOVO is compatible with polypropylene (PP), polycarbonate (PC), polyethylene (PE), stainless steel (SS), polyvinylchloride (PVC), and polyurethane (PUR). Preparation of the Syringe OCREVUS ZUNOVO should be prepared by a healthcare professional. Immediate use is recommended, as OCREVUS ZUNOVO does not contain any antimicrobial preservative. If the dose is not administered immediately, refer to "Storage of the Syringe" below. Remove the vial from refrigerated storage and allow the solution to acclimate to room temperature at or below 25°C (77°F). Withdraw the entire contents of OCREVUS ZUNOVO solution from the vial with a syringe and transfer needle (21G needle recommended). Do not dilute. Remove the transfer needle from the syringe and replace with a subcutaneous infusion set (e.g., winged/butterfly) containing a 24G-26G needle for injection. Use a subcutaneous infusion set with a priming volume NOT to exceed 0.8 mL for administration. Prime the subcutaneous infusion line with the drug product solution to eliminate the air in the infusion line and stop before the fluid reaches the needle. Ensure the syringe contains exactly 23 mL of drug product solution after priming and expelling any excess volume from the syringe. Administer immediately to avoid needle clogging. DO NOT store the prepared syringe that has been attached to the already primed subcutaneous infusion set. Administration Administer 23 mL of OCREVUS ZUNOVO subcutaneously in the abdomen over approximately 10 minutes. DO NOT administer the remaining priming volume in the subcutaneous infusion set to the patient. The recommended injection site is the abdomen, except for 2 inches (5 cm) around the navel. Do not administer OCREVUS ZUNOVO injections into areas where the skin is red, bruised, tender, or hard, or areas where there are moles or scars. Storage of the Syringe If the dose is not to be administered immediately, use aseptic technique to withdraw the entire OCREVUS ZUNOVO contents from the vial into the syringe to account for the dose volume (23 mL) plus the priming volume for the subcutaneous infusion set. Replace the transfer needle with a syringe closing cap. DO NOT attach a subcutaneous infusion set. If not used immediately, the closed syringe can be refrigerated (2°C to 8°C [36°F to 46°F]) for up to 72 hours followed by 8 hours at ambient temperatures at or below 25°C (77°F) in diffuse daylight. If the prepared syringe was stored at 2°C to 8°C (36°F to 46°F), allow the syringe to acclimate to room temperature prior to administration.
