  • 02 Jun 2021Pharmacokinetic, efficacy and adverse events data from a phase II TULIP-LN1 trial in Lupus nephritis presented at the 22nd Annual Congress of the European League Against Rheumatism (EULAR-2021)

Anifrolumab, sold under the brand name Saphnelo, is a monoclonal antibody used for the treatment of systemic lupus erythematosus (SLE).[1][2] It binds to the type I interferon receptor, blocking the activity of type I interferons such as interferon-α and interferon-β.[medical citation needed]

Anifrolumab was approved for medical use in the United States in August 2021.[1][3][4][5]

Anifrolumab is a monoclonal antibody that inhibits type 1 interferon receptors, indicated in the treatment of moderate to severe systemic lupus erythematosus.

Anifrolumab, or MEDI-546, is a type 1 interferon receptor (IFNAR) inhibiting IgG1κ monoclonal antibody indicated in the treatment of adults with moderate to severe systemic lupus erythematosus.7,11 The standard therapy for systemic lupus erythematosus consists of antimalarials like hydroxychloroquine, glucocorticoids like dexamethasone, and disease modifying antirheumatic drugs like methotrexate.8,11

Three monoclonal antibodies (anifrolumab, rontalizumab, and sifalimumab) that target the type 1 interferon pathway entered clinical trials as potential treatments for systemic lupus erythematosus, but so far only anifrolumab has been approved.3

The design of early clinical trials of anti-interferon treatments such as anifrolumab, rontalizumab, and sifalimumab have come under criticism.3 The design of the clinical trials use different definitions of autoantibody positivity, making comparison between trials difficult; all trials involve large portions of patients also using corticosteroids, which may alter patient responses in the experimental and placebo groups; and patient populations were largely homogenous, which may have increased the odds of success of the trial.3

Anifrolumab has also been investigated for the treatment of Scleroderma.1

Anifrolumab was granted FDA approval on 30 July 2021.11

Adverse effects

The most common adverse effect was shingles, which occurred in 5% of patients in the low-dose group, to 10% in the high-dose group, and to 2% in the placebo group. Overall adverse effect rates were comparable in all groups.[6]

History

The drug was developed by MedImmune, a unit of AstraZeneca, which chose to move anifrolumab instead of sifalimumab into phase III trials for lupus in 2015.[7][8][9]

Clinical trial results

Anifrolumab failed to meet its endpoint of significant reduction in disease as assessed by the SLE Responder Index 4 instrument in the TULIP 1 phase III trial.[10] This multi-center, double-blind, placebo-controlled study followed adults with moderate to severe SLE over the course of one year. Preliminary results were announced on 31 August 2018.

Names

Anifrolumab is the international nonproprietary name (INN).[11]
