Side effects
The following clinically significant adverse reactions are also discussed elsewhere in the labeling: • Serious Infections [see Warnings and Precautions (5.1) ] • Hypersensitivity Reactions Including Anaphylaxis [see Warnings and Precautions (5.2) ] • Malignancy [see Warnings and Precautions (5.3) ] Most common adverse drug reactions (incidence ≥5%) are nasopharyngitis, upper respiratory tract infections, bronchitis, infusion related reactions, herpes zoster and cough. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact AstraZeneca at 1-800-236-9933 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. Adverse Reactions with Intravenous Administration The safety of SAPHNELO was assessed in adult patients with moderate to severe SLE who received SAPHNELO 300 mg by intravenous infusion every 4 weeks (N=459) for 52 weeks, compared to placebo (N=466) in controlled clinical trials (Trials 1, 2 and 3) [see Clinical Studies (14.1) ]. The population studied had a mean age of 41 years (range: 18 to 69), of which 93% were female, 60% White, 13% Black/African American, and 10% Asian. In the…
Warnings
Important safety information
Serious Infections: Serious and sometimes fatal infections have occurred in patients receiving SAPHNELO. SAPHNELO increases the risk of respiratory infections and herpes zoster. Avoid initiating treatment during an active infection. Consider the individual benefit-risk if using in patients with severe or chronic infections. Consider interrupting therapy with SAPHNELO if patients develop a new infection during treatment. ( 5.1 ) • Hypersensitivity Reactions Including Anaphylaxis: Serious hypersensitivity reactions including anaphylaxis and angioedema have been reported. ( 5.2 ) • Malignancy: Consider the individual benefit-risk in patients with known risk factors for malignancy prior to prescribing SAPHNELO. ( 5.3 ) • Immunizations: Avoid use of live or live-attenuated vaccines in patients receiving SAPHNELO. ( 5.4 ) • Not Recommended for Use with Other Biologic Therapies. ( 5.5 ) 5.1 Serious Infections Serious and sometimes fatal infections (including COVID‑19) have occurred in patients receiving immunosuppressive agents, including SAPHNELO. In controlled trials, fatal infections occurred more frequently in patients receiving SAPHNELO [see Adverse Reactions (6.1) ] . In controlled trials, SAPHNELO increased the risk of respiratory infections and herpes zoster (disseminated herpes zoster events have been reported) [see Adverse Reactions (6.1) ] . Avoid initiating treatment with SAPHNELO in patients with any clinically significant active infection until the infection is resolved or adequately treated. Consider the benefit and risk of administering SAPHNELO in patients with a chronic infection, a history of recurrent infections, or known risk factors for infection. Instruct patients to seek medical advice if signs or symptoms of a clinically significant infection occur. If a patient develops an infection or is not responding to standard anti-infective therapy while on SAPHNELO, monitor the patient closely and consider interrupting SAPHNELO until the infection resolves. 5.2 Hypersensitivity Reactions Including Anaphylaxis Serious hypersensitivity reactions (including anaphylaxis) have been reported following SAPHNELO administration [see Contraindication (4) ] . Events of angioedema have also been reported [see Adverse Reactions (6.1) ] . Other hypersensitivity reactions and infusion-related reactions have occurred following administration of SAPHNELO [see Adverse Reactions (6.1) ] . Consider pre-medication before infusion of SAPHNELO for patients with a history of these reactions. SAPHNELO should be administered by healthcare providers prepared to manage hypersensitivity reactions, including anaphylaxis, and infusion-related reactions. If a serious infusion-related or hypersensitivity reaction (e.g., anaphylaxis) occurs, immediately interrupt the administration of SAPHNELO and initiate appropriate therapy. 5.3 Malignancy There is an increased risk of malignancies with the use of immunosuppressants. The impact of SAPHNELO treatment on the potential development of malignancies is not known. Consider the individual benefit-risk in patients with known risk factors for the development or reoccurrence of malignancy prior to prescribing SAPHNELO. In patients who develop malignancies, consider the benefit-risk of continued treatment with SAPHNELO. 5.4 Immunizations Update immunizations, according to current immunization guidelines, prior to initiating SAPHNELO therapy. Avoid concurrent use of live or live-attenuated vaccines in patients treated with SAPHNELO. 5.5 Not Recommended for Concomitant Use with Other Biologic Therapies SAPHNELO has not been studied in combination with other biologic therapies, including B-cell-targeted therapies. Therefore, use of SAPHNELO is not recommended for use in combination with biologic therapies.
