Uses
1 INDICATIONS AND USAGE VEOPOZ is indicated for the treatment of adult and pediatric patients 1 year of age and older with CD55-deficient protein-losing enteropathy (PLE), also known as CHAPLE disease.

Dosage
2 DOSAGE AND ADMINISTRATION See the full prescribing information for meningococcal vaccine and prophylaxis recommendations prior to the first dose of VEOPOZ. ( 2.1 ) Recommended Dosage: Day 1 (loading dose): Administer a single 30 mg/kg dose by intravenous infusion after dilution. ( 2.2 ) Day 8 and thereafter (maintenance dosage): Inject 10 mg/kg as a subcutaneous injection once weekly starting on Day 8. The maintenance dosage may be increased to 12 mg/kg once weekly if there is inadequate clinical response after at least 3 weekly doses (i.e., starting from Week 4). The maximum maintenance dosage is 800 mg once weekly. ( 2.2 ) See full prescribing information for instructions on preparation and administration.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Serious Meningococcal Infections [see Warnings and Precautions (5.1) ] Other Bacterial Infections [see Warnings and Precautions (5.2) ] Systemic Hypersensitivity Reactions [see Warnings and Precautions (5.3) ] Immune Complex Formation [see Warnings and Precautions (5.4) ] Most common adverse reactions (in two or more patients) are: upper respiratory tract infection, fracture, urticaria, and alopecia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Regeneron at 1-855-583-6769 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
Interactions
7 DRUG INTERACTIONS Intravenous Immunoglobulin : May decrease pozelimab concentrations; avoid concomitant use. If concomitant use cannot be avoided, monitor patients for worsening of clinical signs and symptoms of disease. ( 7.1 ) 7.1 Intravenous Immunoglobulin VEOPOZ has not been studied in combination with intravenous immunoglobulin. Intravenous immunoglobulin may interfere with the endosomal neonatal Fc receptor (FcRn) recycling mechanism of monoclonal antibodies such as pozelimab thereby decreasing serum pozelimab concentrations. Avoid concomitant use of intravenous immunoglobulin with VEOPOZ. If concomitant use cannot be avoided, monitor patients for worsening of clinical signs and symptoms of CD55-deficient PLE [see Clinical Pharmacology (12.3) ] .
Warnings
WARNING: SERIOUS MENINGOCOCCAL INFECTIONS Life-threatening and fatal meningococcal infections have occurred in patients treated with complement inhibitors. Meningococcal infection may become rapidly life-threatening or fatal if not recognized and treated early. 5 WARNINGS AND PRECAUTIONS Other Bacterial Infections : Interrupt treatment with VEOPOZ in patients who are undergoing treatment for a serious encapsulated bacterial infection until the infection is resolved. ( 5.2 ) Systemic Hypersensitivity Reactions : Interrupt infusion and institute appropriate supportive measures if signs of cardiovascular instability or respiratory compromise occur. ( 5.3 ) Immune Complex Formation : Transition between other complement inhibitors has resulted in decreased drug concentrations and possible hypersensitivity reactions. Consider this potential if switching complement inhibitors to VEOPOZ. 4 CONTRAINDICATIONS VEOPOZ is contraindicated in: Patients with unresolved Neisseria meningitidis infection [see Warnings and Precautions (5.1) ] . VEOPOZ is contraindicated in patients with unresolved Neisseria meningitidis infection. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Although there are no data on VEOPOZ use in pregnant women to inform a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes, monoclonal antibodies can be actively transported across the placenta . In an animal reproduction study in monkeys, pozelimab-bbfg did not adversely affect embryofetal or postnatal development when administered from pregnancy confirmation through parturition at doses that produced exposure up to 3.3 to 3.8 times the predicted clinical exposures (on an AUC basis; see Data ).
Storage
Store VEOPOZ vial refrigerated at 2°C to 8°C (36°F to 46°F) in the original carton to protect from light. Do not freeze. Do not shake. Discard unused portion.
