Key Limitations

  • Clinical assessors, but not patients, were blinded to the study drug. Double blinding was not feasible due to logistical barriers with masking adalimumab
  • Small sample size
  • Exploratory analyses; statistical significance of differences in response rates could not be assessed
  • Larger clinical studies are warranted to confirm the findings from this study

Selected Important
Safety Information

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 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.

The Important Safety Information is derived from the Clinical Trial Safety Data contained within the Full Prescribing Information.

Patients were anti-CCP+ and RF+, biologic-naïve, and had moderate to severe RA for
≤12 months. Patients were randomized 1:1 to ORENCIA SC (125 mg weekly) + MTX (n=40) or adalimumab SC (40 mg biweekly) + MTX (n=40) for 6 months.1 Patients receiving adalimumab switched to ORENCIA (in an open-label period) following a 6-week washout period.1

*Clinical assessors were blinded to the study drug. Double blinding was not feasible because of the logistic barriers to masking adalimumab. Both groups received maximum tolerated (15-25 mg) stable doses of oral MTX weekly. Patients could discontinue after the single-blinded (short-term treatment) period and continue to follow-up.

Safety Information

Hypersensitivity: 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.

Results from a Head-to-Head Noninferiority Trial vs adalimumab

AMPLE was a 2-year Phase IIIb, head-to-head noninferiority trial of adult MTX-IR patients, and is not contained within the Full Prescribing Information.2 It is a supportive trial to the AGREE Registrational Trial, which was studied in MTX-naïve patients and had a different comparator. For more information on AGREE, please see below and the Full Prescribing Information.

Patients were randomized to ORENCIA SC + MTX (n=318) or adalimumab SC + MTX (n=328).2 45% and 47% of patients were anti-CCP+, while 75.5% and 77.4% of patients were RF+ in the trial, respectively.2,3

Patients were required to have moderate to severe RA for ≤5 years, be MTX-IR and biologic-naïve, and have ≥3.2 DAS28-CRP and a history of ≥1 of the following: seropositivity for anti-CCP or RF, or an elevated ESR or CRP level.7

Key limitations of the trial2

Double blinding was not feasible due to difficulty in masking administration of adalimumab.

  • Patients were not blinded to study drug
  • However, clinical assessors and radiographic readers were blinded to mitigate this limitation

Patients achieved comparable efficacy with ORENCIA SC + MTX vs adalimumab SC + MTX—ACR rates were sustained from Year 1 to Year 22,7

Selected Important
Safety Information

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.

Safety Information

Immunizations: Prior to initiating ORENCIA in pediatric and adult patients, update vaccinations in accordance with current vaccination guidelines. 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.

Summary of safety at 1-year in the AGREE trial

The AGREE trial was an active-controlled clinical trial in methotrexate-naive patients. The safety experience in these patients was consistent with the patients studied across
5 clinical trials for ORENCIA IV. Please refer to the Pooled Safety below and Full Prescribing Information.

Selected Important Safety Information

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.

509 adult patients with early moderate to severe RA (≤2 years) who were MTX-naïve* were randomly assigned to treatment groups: ORENCIA IV + MTX (n=256) and placebo + MTX (n=253). ORENCIA IV (~10 mg/kg based on patient weight) was administered on Days 1, 15, and 29, and every 4 weeks thereafter. MTX was initially dosed at 7.5 mg/week and subsequently increased to 15 mg at Week 4 and to 20 mg at Week 8. Dose reduction was permitted to a minimum of 15 mg/week due to toxicity or intolerability.4

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).

Pooled Safety Results9

Based on treatment of 2944 patients (1955 patients treated with ORENCIA IV, 989 with placebo) across 5 double-blind, placebo-controlled studies of 6 months or 1 year (101-100, 101-101, AIM, ASSURE, ATTAIN). A subset of these patients received concomitant biologic DMARD therapy, such as a TNF antagonist (204 patients with ORENCIA, 134 with placebo). The concomitant use of ORENCIA with a TNF antagonist is not recommended.

Most serious adverse reactions9

The most serious adverse reactions associated with ORENCIA therapy were serious infections and malignancies. In patients taking ORENCIA IV (n=1955),* the rate of serious infections was 3.0% and the rate of malignancies was 1.3%. In patients taking placebo (n=989), the rate of serious infections was 1.9% and the rate of malignancies was 1.1%.

Adverse reactions most frequently resulting in clinical intervention9

The adverse reactions most frequently resulting in clinical intervention (interruption or discontinuation of ORENCIA) were due to infection. The most frequently reported infections resulting in dose interruption were upper respiratory tract infection (1%), bronchitis (0.7%), and herpes zoster (0.7%). The most frequent infections resulting in discontinuation were pneumonia (0.2%), localized infection (0.2%), and bronchitis (0.1%).

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 events 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. A pregnancy registry has been established to monitor pregnancy outcomes in women exposed to ORENCIA during pregnancy. Healthcare professionals are encouraged to register patients by calling 1-877-311-8972.

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%), pneumonia (19%, 12%, and 10%), epistaxis (12%, 16%, and 10%), acute kidney injury (9%, 15%, and 10%), and hypermagnesemia (5%, 18%, 10%).

Incidence rates of grade 3 or 4 adverse reactions were the same as incidence rates of all grades, with the exception of grade 3 or 4 pyrexia in all arms (9% [7/8 cohort], 10% [8/8 cohort, ORENCIA arm], and 4% [8/8 cohort, placebo arm]), pneumonia in the 8/8 cohort placebo arm (9%) and acute kidney injury in the 7/8 cohort ORENCIA arm (7%). Clinically relevant adverse reactions in <10% of patients who received ORENCIA in combination with calcineurin inhibitor and methotrexate in Study GVHD-1 included EBV reactivation.

Note concerning ORENCIA administration options: ORENCIA may be administered as an intravenous infusion only for patients 6 years of age and older. PJIA 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 may only be administered as an intravenous (IV) infusion for the prophylaxis of aGVHD in patients undergoing HSCT. The safety and effectiveness of ORENCIA have not been established in pediatric patients younger than 2 years of age for prophylaxis of aGVHD.
