11 DESCRIPTION Abatacept is a selective T-cell costimulation modulator. Abatacept is a soluble fusion protein that consists of the extracellular domain of human cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) linked to the modified Fc (hinge, CH2, and CH3 domains) portion of human immunoglobulin G1 (IgG1). Abatacept is produced by recombinant DNA technology in a mammalian cell expression system. The apparent molecular weight of abatacept is 92 kilodaltons.

Uses
1 INDICATIONS AND USAGE ORENCIA is a selective T cell costimulation modulator indicated for: • the treatment of adult patients with moderately to severely active rheumatoid arthritis (RA). (1.1) • the treatment of patients 2 years of age and older with moderately to severely active polyarticular juvenile idiopathic arthritis (pJIA). (1.2) • the treatment of patients 2 years of age and older with active psoriatic arthritis (PsA). (1.3) • the prophylaxis of acute graft versus host disease (aGVHD), in combination with a calcineurin inhibitor and methotrexate, in adults and pediatric patients 2 years of age and older undergoing hematopoietic stem cell transplantation (HSCT) from a matched or 1 allele-mismatched unrelated donor.
Dosage
2 DOSAGE AND ADMINISTRATION Intravenous Use for Adult RA (2.1) and Adult PsA (2.3) • Administer at 0, 2, and 4 weeks, and every 4 weeks thereafter, as a 30-minute infusion Body Weight of Patient Dose Number of Vials Less than 60 kg 500 mg 2 60 to 100 kg 750 mg 3 More than 100 kg 1,000 mg 4 Subcutaneous Use for Adult RA (2.1) • Prior to the first subcutaneous dose, may administer an optional loading dose as a single intravenous infusion as per body weight categories above. • Administer 125 mg by subcutaneous injection once weekly (within a day of the intravenous infusion if infusion given). • Patients switching from intravenous use to subcutaneous use, administer first subcutaneous dose instead of next scheduled intravenous dose.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Increased Risk of Infection with Concomitant Use with TNF Antagonists, Other Biologic RA/PsA Therapy, or JAK Inhibitors [see Warnings and Precautions (5.1) ] • Hypersensitivity Reactions [see Warnings and Precautions (5.2) ] • Infections [see Warnings and Precautions (5.3) ] • Increased Risk of Adverse Reactions When Used in Patients with Chronic Obstructive Pulmonary Disease (COPD) [see Warnings and Precautions (5.5) ] • Immunosuppression [see Warnings and Precautions (5.6) ] • Cytomegalovirus (CMV) and Epstein-Barr Virus (EBV) Reactivation in aGVHD Prophylaxis after Hematopoietic Stem Cell Transplant (HSCT) [see Warnings and Precautions (5.7) ] • Most common adverse event...
Interactions
7 DRUG INTERACTIONS 7.1 Immunosuppressants Concomitant administration of a TNF antagonist with ORENCIA has been associated with an increased risk of serious infections and no significant additional efficacy over use of the TNF antagonists alone. Concurrent therapy with ORENCIA and TNF antagonists is not recommended [see Warnings and Precautions (5.1) ]. There is insufficient experience to assess the safety and efficacy of ORENCIA administered concurrently with other biologic RA therapy, such as anakinra, or other biologic PsA therapy, and JAK inhibitors and therefore such use is not recommended. [see Warnings and Precautions (5.1) ] .
Warnings
5 WARNINGS AND PRECAUTIONS • Concomitant use with a TNF antagonist can increase the risk of infections and serious infections. (5.1) • Hypersensitivity and anaphylaxis have occurred. (5.2) • Serious infections reported. Patients with a history of recurrent infections or underlying conditions predisposing to infections may experience more infections. Discontinue if a serious infection develops. (5.3) • Screen for latent TB infection prior to initiating therapy. Patients testing positive should be treated prior to initiating ORENCIA. (5.3) • Screen for viral hepatitis prior to initiating ORENCIA. (5.3) • Update vaccinations prior to initiating ORENCIA. Live vaccines should not be given concurrently or within 3 months of discontinuation. 4 CONTRAINDICATIONS None. None. (4)
Pregnancy
8.1 Pregnancy Risk Summary The data with ORENCIA use in pregnant women are insufficient to inform on drug-associated risk. However, there are clinical considerations for administering live vaccines to infants who were exposed to ORENCIA while in utero (see Clinical Considerations) . In reproductive toxicology studies in rats and rabbits, no fetal malformations were observed with intravenous administration of ORENCIA during organogenesis at doses that produced exposures approximately 29 times the exposure at the maximum recommended human dose (MRHD) of 10 mg/kg/month on an AUC basis.
Storage
Storage Refrigerate ORENCIA lyophilized powder supplied in a vial at 2°C to 8°C (36°F to 46°F). Do not use beyond the expiration date on the vial. Protect the vials from light by storing in the original package until time of use. Refrigerate ORENCIA solution supplied in a prefilled syringe or ClickJect autoinjector at 2°C to 8°C (36°F to 46°F).
