Important Safety Information 
 for ORENCIA®
                                            (abatacept)
                                        Increased Risk of Infection with Concomitant Use
                                                with TNF Antagonists, Other Biologic RA/PsA Therapy, or JAK Inhibitors:
                                             Concurrent therapy with ORENCIA and a TNF antagonist is not
                                            recommended. In controlled clinical trials, adult moderate to severe
                                            rheumatoid arthritis (RA) patients receiving concomitant intravenous ORENCIA
                                            and TNF antagonist therapy experienced more infections (63% vs 43%) and
                                            serious infections (4.4% vs 0.8%) compared to patients treated with only TNF
                                            antagonists, without an important enhancement of efficacy. Additionally,
                                            concomitant use of ORENCIA with other biologic RA/PsA therapy or JAK
                                            inhibitors is not recommended.
                                        Hypersensitivity Reactions: There were 2
                                            cases (<0.1%; n=2688) of anaphylaxis reactions in clinical trials with
                                            adult RA patients treated with intravenous ORENCIA. Other reactions
                                            potentially associated with drug hypersensitivity, such as hypotension,
                                            urticaria, and dyspnea, each occurred in <0.9% of patients. There was one
                                            case of a hypersensitivity reaction with ORENCIA in pJIA clinical trials
                                            (0.5%; n=190). In postmarketing experience, fatal anaphylaxis following the
                                            first infusion of ORENCIA and life-threatening cases of angioedema have been
                                            reported. Angioedema has occurred as early as after the first dose of
                                            ORENCIA, but also has occurred with subsequent doses. Angioedema reactions
                                            have occurred within hours of administration and in some instances had a
                                            delayed onset (i.e., days). Appropriate medical support measures for
                                            treating hypersensitivity reactions should be available for immediate use.
                                            If an anaphylactic or other serious allergic reaction occurs, administration
                                            of intravenous or subcutaneous ORENCIA should be stopped immediately and
                                            permanently discontinued, with appropriate therapy instituted.
                                        Infections: Serious infections, including
                                            sepsis and pneumonia, were reported in 3% and 1.9% of RA patients treated
                                            with intravenous ORENCIA and placebo, respectively. Some of these infections
                                            have been fatal. Many of the serious infections have occurred in patients on
                                            concomitant immunosuppressive therapy which, in addition to their underlying
                                            disease, could further predispose them to infection. Caution should be
                                            exercised in patients with a history of infection or underlying conditions
                                            which may predispose them to infections. Treatment with ORENCIA should be
                                            discontinued if a patient develops a serious infection. Patients should be
                                            screened for tuberculosis and viral hepatitis in accordance with published
                                            guidelines, and if positive, treated according to standard medical practice
                                            prior to therapy with ORENCIA.
                                        Immunizations: Prior to initiating ORENCIA
                                            in pediatric and adult patients, update vaccinations in accordance with
                                            current vaccination guidelines. ORENCIA-treated patients may receive current
                                            non-live vaccines. Live vaccines should not be given concurrently with
                                            ORENCIA or within 3 months after discontinuation. ORENCIA may blunt the
                                            effectiveness of some immunizations. In addition, it is unknown if the
                                            immune response of an infant who was exposed in utero to abatacept and
                                            subsequently administered a live vaccine is impacted. Risks and benefits
                                            should be considered prior to vaccinating such infants.
                                        Increased Risk of Adverse Reactions When Used in
                                                Patients with Chronic Obstructive Pulmonary Disease (COPD): In
                                            Study V, adult COPD patients treated with ORENCIA for RA developed adverse
                                            reactions more frequently than those treated with placebo, including COPD
                                            exacerbations, cough, rhonchi, and dyspnea. In the study, 97% of COPD
                                            patients treated with ORENCIA developed adverse events versus 88% treated
                                            with placebo. Respiratory disorders occurred more frequently in patients
                                            treated with ORENCIA compared to those on placebo (43% vs 24%,
                                            respectively), including COPD exacerbation, cough, rhonchi, and dyspnea. A
                                            greater percentage of patients treated with ORENCIA developed a serious
                                            adverse event compared to those on placebo (27% vs 6%), including COPD
                                            exacerbation [3 of 37 patients (8%)] and pneumonia [1 of 37 patients (3%)].
                                            Use of ORENCIA in patients with COPD should be undertaken with caution, and
                                            such patients monitored for worsening of their respiratory status.
                                        Immunosuppression: In clinical trials in
                                            adult RA patients, a higher rate of infections was seen in ORENCIA-treated
                                            patients compared to placebo-treated patients. The impact of treatment with
                                            ORENCIA on the development and course of malignancies is not fully
                                            understood. There have been reports of malignancies, including skin cancer
                                            in patients receiving ORENCIA. Periodic skin examinations are recommended
                                            for all ORENCIA-treated patients, particularly those with risk factors for
                                            skin cancer.
                                        Cytomegalovirus (CMV) and Epstein-Barr Virus (EBV)
                                                Reactivation in aGVHD Prophylaxis after Hematopoietic Stem Cell
                                                Transplant (HSCT): Post-Transplant Lymphoproliferative Disorder
                                            (PTLD) occurred in patients who received ORENCIA for aGVHD prophylaxis
                                            during unrelated HSCT. Of 116 patients who received ORENCIA, 4 patients
                                            (3.4%) experienced PTLD. All the PTLD events were associated with
                                            Epstein-Barr virus (EBV) infection. The range of time to onset of the event
                                            was 49 to 89 days post-transplant. Monitor patients for EBV reactivation in
                                            accordance with institutional practices. Before administering ORENCIA,
                                            provide recommended prophylaxis for EBV infection and continue for 6 months
                                            post-transplantation to prevent EBV-associated PTLD. Cytomegalovirus (CMV)
                                            invasive disease occurred in patients who received ORENCIA for aGVHD
                                            prophylaxis during unrelated HSCT. Of 116 patients who received ORENCIA, 7%
                                            (n=8) experienced CMV invasive diseases up to day 225 post-transplant. The
                                            median time to onset of the event was 91 days post-transplant. CMV invasive
                                            diseases predominantly involved the gastrointestinal tract. Monitor patients
                                            for CMV infection/reactivation for 6 months post-transplant regardless of
                                            the results of donor and recipient pre-transplant CMV serology. Consider
                                            prophylaxis for CMV infection/reactivation during treatment and for six
                                            months following HSCT.
                                        Blood Glucose Testing: ORENCIA for
                                            intravenous administration contains maltose, which may result in falsely
                                            elevated blood glucose readings on the day of infusion when using blood
                                            glucose monitors with test strips utilizing glucose dehydrogenase
                                            pyrroloquinoline quinone (GDH-PQQ). Consider using monitors and
                                            advising patients to use monitors that do not react with maltose, such as
                                            those based on glucose dehydrogenase nicotine adenine dinucleotide 
                                                (GDH-NAD), glucose oxidase or glucose hexokinase test methods.
                                            ORENCIA for subcutaneous (SC) administration does not contain maltose;
                                            therefore, patients do not need to alter their glucose monitoring.
                                        Pregnancy: There are no adequate and
                                            well-controlled studies of ORENCIA use in pregnant women and the data with
                                            ORENCIA use in pregnant women are insufficient to inform on drug-associated
                                            risk.
                                            
                                        
                                        Lactation: There is no information regarding
                                            the presence of abatacept in human milk, the effects on the breastfed
                                            infant, or the effects on milk production. However, abatacept was present in
                                            the milk of lactating rats dosed with abatacept.
                                        Most Serious Adverse Reactions: In
                                            controlled clinical trials, adult RA patients experienced serious infections
                                            (3% ORENCIA vs 1.9% placebo) and malignancies (1.3% ORENCIA vs 1.1%
                                            placebo). In the GVHD-1 study, serious adverse reactions reported in >5% of
                                            patients who received ORENCIA in combination with a calcineurin inhibitor
                                            and methotrexate included pyrexia (20%), pneumonia (8%), acute kidney injury
                                            (7%), diarrhea (6%), hypoxia (5%), and nausea (5%).
                                        Malignancies: The overall frequency of
                                            malignancies was similar between adult RA patients treated with ORENCIA or
                                            placebo. However, more cases of lung cancer were observed in patients
                                            treated with ORENCIA (0.2%) than those on placebo (0%). A higher rate of
                                            lymphoma was seen compared to the general population; however, patients with
                                            RA, particularly those with highly active disease, are at a higher risk for
                                            the development of lymphoma. The potential role of ORENCIA in the
                                            development of malignancies in humans is unknown.
                                        Most Frequent Adverse Events (≥10%):
                                            Headache, upper respiratory tract infection, nasopharyngitis, and nausea
                                            were the most commonly reported adverse events in the adult RA clinical
                                            studies. Other events reported in ≥5% of pJIA patients were diarrhea, cough,
                                            pyrexia, and abdominal pain. In general, the adverse events in pediatric
                                            pJIA and adult PsA patients were similar in frequency and type to those seen
                                            in adult RA patients. The most frequent adverse reactions of all grades
                                            reported in ≥10% of patients with aGVHD who received ORENCIA with a
                                            difference of ≥2% for the 7/8 cohort, 8/8 cohort ORENCIA arm, and 8/8 cohort
                                            placebo arm, respectively, were anemia (56%, 69%, and 57%), CD4 lymphocytes
                                            decreased (14%, 14%, and 9%), hypertension (49%, 43%, and 38%), pyrexia
                                            (28%, 19%, and 20%), CMV reactivation/CMV infection (26%, 32%, and 22%),

                                        Note concerning ORENCIA administration
                                                options: ORENCIA may be administered as an intravenous infusion
                                            only for patients 6 years of age and older. PJIA or pediatric PsA patients
                                            may self-inject with ORENCIA or the patient’s caregiver may administer
                                            ORENCIA if both the healthcare practitioner and the parent/legal guardian
                                            determines it is appropriate. The ability of pediatric patients to
                                            self-inject with the autoinjector has not been tested. ORENCIA for the
                                            prophylaxis of aGVHD in patients undergoing HSCT may only be administered as
                                            an intravenous (IV) infusion. The safety and effectiveness of ORENCIA have
                                            not been established in pediatric patients younger than 2 years of age for
                                            prophylaxis of aGVHD.
