Thanks to anti–tumor necrosis factor inhibitors and other highly effective biologic therapies, rheumatologists are increasingly embracing treat to target, a strategy in which patients are closely monitored and medications adjusted until a patient has the least disease activity possible.
Ample evidence from randomized, controlled trials has shown treat to target – sometimes referred to as tight control – to result in better outcomes than standard therapy in rheumatoid arthritis patients.
But in psoriatic arthritis (PsA), a more heterogeneous disorder with skin and nail manifestations as well as joint and connective tissue involvement, remission has historically been less well defined. Only in recent years have endpoints been developed and validated for minimal disease activity in PsA, and evidence in support of a treat-to-target approach is now slowly trickling in.
At the annual European Congress of Rheumatology, Dr. Arthur Kavanaugh of the University of California, San Diego, presented results from a 5-year extension of a randomized, controlled trial of golimumab in patients with PsA that showed better long-term outcomes in those able to achieve minimal disease activity (MDA) through a treat-to-target strategy.
"I think [the study] does provide some evidence suggesting that treat to target could well be a valuable goal for PsA, Dr. Kavanaugh said. "Right now, RA has the advantage of more studies showing this."
Dr. Kavanaugh and his colleagues’ study used data from an open-label extension of a clinical trial in which about 400 patients were randomized to receive golimumab at 50 mg or 100 mg, or placebo; all placebo patients were crossed over to golimumab treatment at 24 weeks and during the long-term, open-label extension of the trial, were followed for as long as 252 weeks. Patients were assessed at 14, 24, and 52 weeks, then yearly until week 252. The investigators used a validated composite endpoint that included measures of skin, joint, and enthesis involvement.
About half of the patients (44.2% of those randomized to placebo and 51.7% of those randomized to active treatment) achieved persistent MDA over three or more consecutive time points during follow-up, and investigators saw significantly better clinically meaningful Health Assessment Questionnaire improvement and less radiographic progression in patients who had achieved MDA, regardless of treatment allocation.
Patients who achieved MDA after crossing over had improvements that were similar to those who started on golimumab at baseline, suggesting that delayed treatment initiation does not result in a worsening of physical function or radiographic progression.
"When it comes to patients, we cannot always control when we will see them in the course of disease," Dr. Kavanaugh said. "These data suggest that even though a patient may show up with months of uncontrolled disease, it is still a viable goal to treat them to try to get MDA."
Dr. Kavanaugh said that further studies in PsA patients were needed to confirm that treat-to-target strategies resulted in better long-term disease outcomes. "As always in medicine, it is important to have verification from multiple studies. It would be helpful to have data from studies using medications with other mechanisms of action to support treat to target," he added.
Dr. Kavanaugh disclosed research and grant support from Abbott, Amgen, Janssen, and UCB. His coauthors on the study disclosed financial support from additional manufacturers, and three were employees of Janssen.
