A startling new statistic reveals that only 18% of U.S. physicians now work in MD-owned practices—down from a majority just a few years ago—marking a seismic shift toward corporate and hospital employment. Jack Cush, host of the Rheumnow Podcast, expresses concern over this trend, noting that while corporate gigs offer better pay and benefits, they often demand high-volume, six-to-eight-minute visits that commodify patient care. Amid this backdrop, the episode dives into several key clinical updates: a Japanese study shows rituximab may be a powerful option for refractory neuropsychiatric lupus, with 16 of 17 patients showing significant improvement; a promising phase 2 trial of IMVT-1402 (a monoclonal antibody targeting FCRN) reports strong ACR20, 50, and 70 responses in refractory RA patients; and a major head-to-head trial finds bimikizumab (an IL-17 inhibitor) significantly outperforms risankizumab (an IL-23 inhibitor) in achieving ACR50 at week 16. The episode also debunks myths—like the supposed danger of NSAIDs in early pregnancy, which a large study found to be safe—and raises red flags about Avacapan, a drug linked to 20 deaths in Japan due to a rare, fatal bile duct syndrome. Finally, Cush emphasizes the critical importance of clinical exams over lab tests for monitoring disease activity, advocating for tools like the GAS score to track patient progress reliably.
Only 18% of U.S. physicians now work in MD-owned practices—down from a majority just a few years ago.
Corporate employment of physicians rose to 550,000 in January 2026, with only 121,000 in independent practices.
Rituximab showed significant improvement in 16 of 17 patients with refractory neuropsychiatric lupus in a Japanese observational study.
IMVT-1402, a phase 2 trial drug targeting FCRN, achieved 73% ACR20 response in refractory RA patients.
Bimikizumab outperformed risankizumab in ACR50 at week 16 (49% vs. 38%) in a head-to-head trial of psoriatic arthritis patients.

Opening: Room IQ Quiz & Physician Employment Trends
Jack Cush kicks off the episode with a reflection on the Room IQ quiz, noting a 66% pass rate and highlighting a question about TNF inhibitors in RA patients with cancer—where the correct answer was 'none of the above.' He then introduces a startling statistic: only 18% of U.S. physicians now work in MD-owned practices, with 550,000 employed by hospitals or corporate entities.
Corporate Medicine: Benefits and Risks
Cush reflects on his own experience running a private practice before being acquired, noting that while corporate employment offers better pay and benefits, it pressures physicians to perform high-volume, short visits—reducing time for patient care and increasing burnout risk.
Fatigue in Lupus: Not Just Activity
An NIH cohort study reveals that fatigue in lupus is more strongly linked to organ damage and obesity than to physical activity levels, challenging common assumptions about its causes.
Rituximab for Refractory Neuropsychiatric Lupus
“16 out of 17 had significant improvement. What's the metric? They don't say. One had partial improvement. And none of these patients had a relapse of their neuropsychiatric lupus.”
IMVT-1402: A Promising New RA Therapy
“ACR 20 was 73%. Holy cow! But it's open-label. Everybody knew they were getting drugged. ACR 50 was 54%, and ACR 70 was 36%. Those are good numbers.”
“The FDA may shut down the drug. Again, the incidence here is really, really low. The problem as I see it is that FDA decisions, even though there's an incredibly low incidence of these events, can be driven by a serious deadly event that's never been described before.”
“The primary endpoint was ACR50, and it was significantly in favor of bimikizumab 49% versus risinikizumab 38%. That was significant.”
“The clinical exam is the best way to monitor and outperforms any laboratory study by far. That's it for this week.”
