garadacimab-gxii · by csl behring llc
Garadacimab-gxii, an activated Factor XII (FXIIa) inhibitor, is a recombinant, fully human, monoclonal antibody (IgG4/ λ -light chain) produced in Chinese Hamster Ovary (CHO) cells. Based on the amino acid sequence, the molecular weight of garadacimab-gxii is approximately 148 kDa. ANDEMBRY (garadacimab-gxii) injection is a sterile, preservative-free, slightly opalescent to clear, brownish-yellow to yellow solution for subcutaneous use. Each 1.2 mL prefilled autoinjector or prefilled syringe with needle safety device of ANDEMBRY contains 200 mg of garadacimab-gxii, arginine monohydrochloride (37.9 mg), histidine (3.7 mg), polysorbate 80 (0.24 mg), proline (19.3 mg), and water for injection, USP. The pH is 6.1.
Recommended Dosage : Initial loading dose of 400 mg (two 200 mg injections) administered subcutaneously followed by maintenance dosage of 200 mg once monthly. ( 2.1 ) Subcutaneous use only. ( 2.2 ) Patients may self-administer. See full prescribing information for preparation and administration instructions. ( 2.2 ) 2.1 Recommended Dosage The recommended dosage of ANDEMBRY is an initial loading dose of 400 mg (two injections of 200 mg) administered subcutaneously on the first day of treatment followed by a maintenance dosage of 200 mg administered subcutaneously every month. Missed Dose(s) If a dose of ANDEMBRY is missed, administer the dose as soon as possible. 2.2 Preparation and Administration Instructions for ANDEMBRY Prefilled Autoinjector and Prefilled Syringe with Needle Safety Device For subcutaneous use only. ANDEMBRY is intended for self-administration or administration by a caregiver. Prior to treatment initiation, train patients/caregivers on proper preparation and subcutaneous (SC) administration technique of ANDEMBRY [see Instructions for Use ] . Prior to administration, remove ANDEMBRY from the refrigerator and allow to sit for 30 minutes at room temperature before use. Inspect ANDEMBRY visually for particulate matter and discoloration prior to administration, whenever solution and container permit. ANDEMBRY is a slightly opalescent to clear, brownish-yellow to…
Most common adverse reactions (incidence ≥ 7%) are nasopharyngitis and abdominal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact CSL Behring at 1-866-915-6958 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials 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 safety of ANDEMBRY reflects the exposure in a total of 164 adult and pediatric patients aged 12 years and older with hereditary angioedema (HAE) from a placebo-controlled study, VANGUARD [see Clinical Studies (14) ] , and an open-label clinical study. Among the 164 patients who received at least one dose of ANDEMBRY 200 mg subcutaneously, 153 (93%) patients were exposed for at least one year. The median duration of ANDEMBRY treatment was 2.6 years. The safety data below is based on the 6-month placebo-controlled study (VANGUARD), in which ANDEMBRY 400 mg was administered subcutaneously as a loading dose followed by 200 mg (N=39) every month in patients with HAE. Demographics of the patients in this study are summarized in Clinical Studies [see Clinical Studies (14) ]. The safety of ANDEMBRY was similar across all subgroups of patients, including analysis by age, sex…

None. None. ( 5 )
Drug Interference with Laboratory Test: ANDEMBRY can prolong activated partial thromboplastin time (aPTT) due to an interaction of garadacimab-gxii with the aPTT assay. ( 7.1 ) 7.1 Drug Interference with Laboratory Test Coagulation Tests ANDEMBRY can prolong activated partial thromboplastin time (aPTT) due to an interaction of garadacimab-gxii with the aPTT assay. The reagents used in the aPTT laboratory test initiate intrinsic coagulation through the activation of FXII in the contact system, therefore inhibition of plasma FXIIa by ANDEMBRY can prolong aPTT in this assay [see Adverse Reactions (6.1) ] .
