What is Abatacept?
Abatacept is a medication used to treat the symptoms of Rheumatoid arthritis as well as to help prevent joint injuries that are caused by these diseases. Abatacept is a prescription drug for children and adults who are at least 2 years old.
Abatacept is also employed for treating active Psoriatic arthritis for adults.
Abatacept does not provide an answer to any autoimmune disease and can only address the symptoms of the disease.
Abatacept is also used for reasons not mentioned in this medication guide.¶
An increased risk of infection when combined use of TNF Antagonists other Biologic RA/PsA Therapy or JAK Inhibitors
In controlled clinical trials conducted in patients suffering from adult RA in which patients received the concomitant intravenous treatment of Abatacept with TNF antagonist therapy suffered more infections (63%against. 43%) and more serious infections (4.4 % against. 0.8 %) as compared to those treated only with antagonists of TNF. These studies failed to show an important increase in effectiveness when Abatacept is administered concurrently together with TNF antagonists. Therefore the use of Abatacept in conjunction with, as well as a TNF antagonist, would not be suggested. When transitioning between TNF antagonist treatment to the Abatacept, patients must be monitored for any signs of infections. Also, concurrent use of Abatacept alongside other biologic RA/PsA therapies or JAK inhibitors is not advised.
In clinical studies with 2688 healthy adult RA patients receiving Abatacept intravenously, there were two instances (<0.1 %) of anaphylaxis-related reactions. Other reactions that could be related to hypersensitivity to medications, like hypertension, urticaria, and dyspnea, all were seen within less than 0.9 % of patients treated with Abatacept. Of the 190 patients treated with Abatacept in clinical trials conducted by pJIA there was one instance of hypersensitivity (0.5 %).
In postmarketing, fatal anaphylaxis has occurred following the initial infusion of Abatacept as well as life-threatening instances of angioedema were reported. Angioedema can occur as early as the day following the initial dose of Abatacept. However, it has also occurred following subsequent doses. Angioedema-related reactions have occurred within hours after administration, and in some instances, they had an extended time of onset (i.e. days).
The appropriate medical support measures to treat hypersensitivity reactions must be readily available to be used immediately should there be a reaction. If an anaphylactic, or other severe allergic reaction is observed the administration of Abatacept intravenous or subcutaneously must be stopped immediately, with appropriate therapy being implemented, and treatment with Abatacept must be stopped permanently.
Sepsis and other serious infections, such as sepsis and pneumonia were reported among patients who receive Abatacept (serious infections were observed in 3 and 1.9 % of RA patients receiving Abatacept or placebo intravenously and placebo, in turn). Certain of these infections are fatal. The majority of serious infections have been reported in patients receiving concomitant immunosuppressive treatments that, along with their existing disease, may increase their risk of contracting infections. A higher incidence of severe infections was reported among adult RA patients who are treated with concomitant anti-TNF antagonists as well as Abatacept in comparison to those who are who were treated by Abatacept by itself
Healthcare providers must be cautious when contemplating the treatment with Abatacept for patients who have an underlying history of frequent infections, or underlying illnesses that can make them susceptible to infection, or chronic localized latent or chronic infections. Patients who contract a new infection during treatment with Abatacept must be closely monitored. The use of Abatacept should be stopped when a patient is diagnosed with an acute infection.
Before beginning Abatacept the patient should be tested for the presence of latent tuberculosis (TB) infection by tuberculin skin tests. Abatacept has not been evaluated for patients who have positive TB tests and the security of Abatacept for patients with latent TB infections is unclear. Patients who test positive for TB in TB screening must be treated in accordance with the standard medical procedure prior to starting treatment with Abatacept.
Antirheumatic treatments have been linked with hepatitis B activation. Thus, the screening of patients for viral liver disease needs to be conducted according to published guidelines before beginning treatment with Abatacept. In clinical trials with Abatacept patients who tested positive for hepatitis, were excluded from the study
Before initiating Abatacept for adult and pediatric patients, it is commended to update vaccines according to current guidelines for vaccination. Abatacept-treated patients can receive current non-live vaccines. Live vaccines shouldn’t be administered in conjunction with Abatacept or for a period of three months following discontinuation. There is no information available regarding the possibility of transmission from people who receive live vaccines to patients taking Abatacept. There are also medical reasons to administer live vaccines in infants exposed to Abatacept in pregnancy. Based on the mechanism by which it exerts effect, Abatacept may blunt the effectiveness of certain vaccinations.
Higher risk of adverse reactions when used in patients with chronic Obstructive Pulmonary Disease (COPD)
In study, adult COPD patients receiving Abatacept to treat RA had adverse events more often than patients who received a placebo treatment, including COPD exacerbations, coughs, and rhonchi, as well as dyspnea. The higher %age of patients who received Abatacept had an adverse event that was serious when compared with patients who received placebo (27 % versus 6. The use of Abatacept for patients suffering from COPD should be done with caution. Patients are monitored for the deterioration of their respiratory conditions.
There is a chance for drugs that block T cells’ activation, like Abatacept, to alter host defenses against malignancies and infections because T cells are the primary source of immune cell responses. In clinical trials conducted on patients suffering from adult RA, a higher frequency of infections was observed in patients treated with Abatacept in comparison to patients treated with placebo. The effect of the treatment of Abatacept on the development and progression of malignancies isn’t fully comprehended. There are reports of skin cancer, among patients who receive Abatacept. A regular skin exam is advised for all patients receiving Abatacept and those with high-risk factors for skin cancer.
Cytomegalovirus (CMV) and Epstein-Barr Virus (EBV) Reactivation in aGVHD Prophylaxis following Hematopoietic Stem Transplantation (HSCT)
Post Transplant Lymphoproliferative Disorder (PTLD) was observed in patients who received Abatacept as GVHD prophylaxis in HSCT that was not related. Of 116 patients treated with Abatacept in 2004, 4 patients (3.4 %) were diagnosed with PTLD. All PTLD instances were linked to Epstein-Barr virus (EBV) infection. Three of the patients had EBV Serology-positive at baseline. One patient was negative at baseline EBV serology but the donor’s EBV serology was not known.
Three of the four patients stopped taking acyclovir on day 30 after the transplant. The time from the onset of the symptoms was between 49 and 89 days after transplantation. Check patients for EBV Reactivation as per the institutional guidelines. Prophylaxis is recommended against EBV infection for six months after transplantation to prevent EBV-associated TLD.
Cytomegalovirus (CMV) an invasive disease was observed among patients receiving Abatacept as GVHD prophylaxis in HSCT that was not related to. Of the 116 patients treated with Abatacept, 7% experienced CMV infected diseases until day 225 following transplant. All patients suffering from CMV infiltrating diseases have CMV seroconversion positive at the time of baseline. The median time between the onset of the disease was 91 days following transplantation. CMV-related diseases that were invasive mostly affected the digestive 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
