Down-regulation of Interferon signature in systemic lupus erythematosus patients by active immunization with Interferon alpha-Kinoid extended follow-up

Interferon-alpha Kinoid (IFN-K) is a therapeutic vaccine composed of IFN-alpha2b coupled to a carrier protein. In a phase I/II placebo-controlled trial, we observed that IFN-K significantly decreases the IFN gene signature in whole blood RNA samples from SLE patients (see GSE39088). Here, we analyzed extended follow-up data from IFN-K-treated patients, in terms of persistence of neutralizing anti-IFN Abs, gene expression profiling and safety.
