Despite negative trial findings, belimumab (Benlysta) remains a valid option for black lupus patients, so long as they have high disease activity and positive serology.
That was just one of the many useful messages from a robust question-and-answer session on Twitter April 23, about important findings from the recent LUPUS 2019 Congress in San Francisco. The Twitter chat was hosted by MDedge Rheumatology and led by Jinoos Yazdany, MD, and Gabriela Schmajuk, MD, both associate professors of rheumatology at the University of California, San Francisco (UCSF). The chat included scores of posts from over a dozen participants, most of them rheumatologists, and it’s worth a recap.
The EMBRACE trial
The belimumab EMBRACE trial was the first topic up to bat. The Food and Drug Administration ordered GlaxoSmithKline to conduct the trial as a condition of approval for lupus in 2011; phase 3 trials found no benefit among a small number of black subjects and even a suggestion of harm.
Although lupus is highly prevalent among black people, and outcomes are generally worse, EMBRACE was the first lupus trial to enroll an entirely black population; 345 patients were treated for a year at 10 mg/kg IV every 4 weeks. Inclusion criteria included disease activity scores of at least 8.
Overall, 49% of belimumab patients, and 42% on placebo, had a positive response, which meant a drop of 4 or more disease activity points, among other things. The difference was not statistically significant (P = .11).
However, GSK’s data showed a statistically significant benefit in favor of belimumab among people who entered with a disease activity score of at least 10 (53% vs. 41% for placebo), as well as for those with low complement levels (47% vs. 25%) and both anti–double stranded DNA antibodies and low complement (45% vs. 24%). Response rates were also significantly higher among the 57% of subjects who lived outside of the United States and Canada.
So what to make of the results?
“The EMBRACE efficacy data seems to reinforce what we already know: belimumab doesn’t work in a lot of patients, and it [has] the best chance of working in patients with higher baseline disease activity,” tweeted Dr. Yazdany.
As for prescribing, Sarah Patterson, MD, a postdoctoral fellow in the UCSF Division of Rheumatology, tweeted that the results “support the use of belimumab for black lupus patients with high disease activity” and positive serology.
For those who don’t fit the treatment profile, “we should take care to not over-use it,” said Megan Clowse, MD, an associate professor of rheumatology at Duke University, Durham, N.C., in a tweet.
The HCQ adherence fail
Poor hydroxychloroquine (HCQ) adherence came up next on Twitter. The chat participants agreed it’s a huge problem, but no one knows why. Perhaps it’s because patients don’t feel a therapeutic effect or perhaps because GI problems and other side effects are worse than doctors think. Maybe there’s simply not enough social support to encourage people to stay on the drug, even though it’s the single most important medication in lupus.
A nine-study meta-analysis presented at LUPUS 2019 suggested a solution: blood levels. The odds of nonadherence were three times higher in patients below threshold HCQ levels, and although not statistically significant, the mean lupus disease activity index score was more than 3 points higher.
A rheumatologist on the chat said that he’s already checking them.
“We have been measuring HCQ for the past 12 months” at Washington University, St. Louis, according to Alfred Kim, MD, PhD, an assistant professor of rheumatology at the school. The data are just now coming in, he said, but it seems to be catching people.
That raised another question on the chat, however: What do you do with people who aren’t down with the program? They’ll be out the door and gone with the wrong words.
“I haven’t figured out the proper tone for when I say ‘So, I see that you haven’t picked up your HCQ in 5 months,’ ” tweeted Dr. Clowse. “It is a really uncomfortable phone call.”
Dr. Kim said that “I ‘gotcha’ them all the time. Guess what typically goes up after they get that 1st HCQ test? Their HCQ levels ... But this rise isn’t durable in our short experience. It goes back down later.”
He tweeted that overall “this is an opportunity to educate patients on the benefits of HCQ ... Most actually do not [know] why they are taking this medication, in our experience.” In another tweet, Dr. Kim said “I tell them I care,” and that checking HCQ levels “is one way of demonstrating how I want to improve their outcomes.”
Tiffany from #LupusChat thought that it’s time for doctors to sit down with patient advocates and hash it out. She tweeted that “I truly feel this would be a positive 1st step ... a two-way conversation that’s non-judgmental and focused on improving” outcomes and quality of life.
Baricitinib for lupus?
The final topic was baricitinib (Olumiant).
There were modest indications of benefit at 4 mg/day oral after 6 months in a phase 2 trial with 314 people. There were also serious infections in 6% versus 2% on 2 mg/day and 1% on placebo. One patient in the 4-mg/day arm (1%) developed deep vein thrombosis (DVT), but they were positive for antiphospholipid antibodies, which raise the clot risk.
Baricitinib is FDA approved as second line at 2 mg/day for adult rheumatoid arthritis; there’s a black box warning of malignancies, thrombosis, and serious infections.
“I’m not sure” the risk-benefit is in the right direction for baricitinib in lupus. “There were a significant number of serious infections ... for not a lot of effect on” disease activity, tweeted the Twitter chat coleader, Dr. Schmajuk. In a separate tweet, she said that, even in nonlupus patients, “we are avoiding [Janus kinase inhibitors] in patients with DVT risk factors. If I were a patient, [I’m] not sure I would want to take the risk.”
“Future studies with larger sample size and longer follow up ... are needed to address some of the concerns related to DVT,” said Zahi Touma, MD, an assistant professor of rheumatology at the University of Toronto.
Despite negative trial findings, belimumab (Benlysta) remains a valid option for black lupus patients, so long as they have high disease activity and positive serology.
