SANDESTIN, FLA. – An array of potential new options for psoriatic arthritis offers new targeted options and poses challenges for how to use the drugs, Arthur Kavanaugh, MD, professor of medicine at the University of California, San Diego, said in a video interview at the annual Congress of Clinical Rheumatology.
“We’re seeing a second wave – a second wave driven by the additional ways that we have to target aspects of the immune system relevant to psoriatic arthritis,” he said.
First used to treat rheumatoid arthritis, monoclonal antibodies to interleukin targets, including IL12 and IL23 (ustekinumab) and IL17 (secukinumab and ixekizumab), have become established psoriatic arthritis therapies. Additionally, the Janus kinase (JAK) inhibitor tofacitinib has become an option.
Other options in the pipeline include the JAK inhibitor baricitinib; the anti-IL23 monoclonal antibodies guselkumab, risankizumab, and tildrakizumab; and even more anti-IL17 therapies, including brodalumab and bimekizumab .
“Now we have the synergy of having novel therapeutic approaches to maybe address some of the different domains of disease,” he said. Despite efforts to develop better biomarkers, it’s hard to predict how an individual patient will respond to a specific therapy. The longer the menu of therapeutic options, the better it is for patients.
As methotrexate remains a go-to treatment for many patients, new data from the SEAM trial assessing etanercept and methotrexate will address the question of whether the conventional drug and tumor necrosis factor inhibitors create therapeutic synergy in patients with psoriatic arthritis.
Dr. Kavanaugh discussed the implications of the trial’s findings, which are expected to go public this summer.
