Unanswered Questions
Dr. Giles noted that the ORAL Surveillance trial has left a number of questions unanswered about the role of JAK inhibitors in managing CVD risk in patients with RA. “The issue that we’re trying to ask is, is it just the TNF inhibitors may be better? Is this a subpopulation issue, or was it just bad luck from the purposes of this one trial? Granted, it was a very large trial, but you can still have luck in terms of getting an effect that’s not accurate.”
Dr. Giles’ “gut feeling” on JAK inhibitors is that they’re not causing harm, but that they’re not as effective as TNF inhibitors in ameliorating CV risks in patients with RA.
Michael S. Garshick, MD, who attended the conference and is head of the cardio-rheumatology program at NYU Langone Health, concurred that a number of unanswered questions persist over the treatment of CVD risk in RA — and autoimmune disease in general.
“I think we’re still trying to prove that DMARDs reduce cardiovascular risk in autoimmune conditions,” he said. “The epidemiologic data would suggest, yes, that inflammation prevention is beneficial for cardiovascular disease, but the TARGET trial suggested that vascular inflammation improved by treating RA, but that biologic therapy wasn’t better than traditional triple therapy.”
Other questions remain unanswered, Dr. Garshick said.
“Is there a specific immunotherapy that is most beneficial to reduce heart disease in patients with an autoimmune condition, whether it’s rheumatoid arthritis, psoriasis, or lupus?”
Dr. Garshick said he’s specifically interested in the residual risk that exists after treating the autoimmunity. “Do you still have a higher risk for heart disease, and if so, why? Is there something else going on that we can’t see?”
The biggest unanswered question, he said, is “How can we do a better job of recognizing heart disease risk in these patients? That’s the low-hanging fruit that people are studying, but across many of those studies, patients have higher rates of blood pressure, cholesterol issues, obesity, diabetes, and many times, we’re not adequately treating these comorbidities.”
That, Dr. Garshick said, may be a result of physician fatigue. “And so [treatment of these comorbidities is] kicked down the road for a year or years,” he added.
Dr. Giles disclosed financial relationships with Pfizer, AbbVie, Eli Lilly, and Novartis. Dr. Garshick disclosed relationships with Kiniksa Pharmaceuticals, Agepha Pharma, Bristol Myers Squibb, and Horizon Therapeutics.
