		The three clinical trials below will be presented at ACR Convergence 2022, the  American College of Rheumatology’s annual meeting, and published by Wiley online in Arthritis & Rheumatology. Arthritis & Rheumatology publishes the highest quality basic and clinical research related to  the rheumatic diseases, encompassing a wide range of areas  of investigative activity. ACR Convergence 2022 will showcase  cutting-edge and timely topics in rheumatology, as well as the  prevention, diagnosis, and treatment of rheumatic diseases and related  comorbid conditions. 
 
 
 
Oral deucravacitinib benefits patients with lupus 
Tyrosine  kinases are enzymes that play central roles in signaling by cytokines  involved in the pathogenesis of autoimmune diseases, including lupus. A  recent phase 2 clinical trial published  by Wiley in Arthritis & Rheumatology has  generated promising results for deucravacitinib, an oral inhibitor of  tyrosine kinase 2 (TYK2), in patients with active lupus. 
 
In the  trial, 363 patients were randomized 1:1:1:1 to placebo or  deucravacitinib 3 mg twice daily, 6 mg twice daily, or 12 mg once daily.  At week 32, the percentage of patients who experienced  a beneficial response (as assessed by various measures of disease  activity) was 34% with placebo compared with 58%, 50%, and 45% with the  respective deucravacitinib regimens.
 
Rates of  adverse events were similar across groups, except for higher rates of  infections and skin-related events, including rash and acne, with  deucravacitinib. Rates of serious adverse events  were comparable, with no deaths, opportunistic infections,  tuberculosis, major adverse cardiovascular events, or thrombotic events  reported.
 
“TYK2  transducer signals a unique set of cytokines that are highly relevant to  SLE,” said corresponding author Eric Morand, MBBS, PhD, of Monash  University. “These results put TYK2 on the map  as a target for lupus and encourage further development of  deucravacitinib in this disease."
 
 
Anesthetics that block nerves around the knee relieve pain in patients with knee osteoarthritis 
Results from a recent clinical trial published by Wiley in Arthritis & Rheumatology demonstrate  that patients with knee osteoarthritis experience short term pain  relief from genicular nerve blocks—or locally injected anesthetics that  block nerves around the knee joint. 
 
In the  trial, 59 patients were randomized to receive a nerve block or a placebo  injection. At baseline and weeks 2, 4, 8 and 12, participants recorded  their pain on a scale of 0 to 10. 
 
Patients  who received a nerve block reported improvement in pain scores at 2, 4,  8 and 12 weeks, compared with baseline, but with diminishing effects  over time. Scores for nerve block versus  placebo at baseline, weeks 2, 4, 8 and 12 were: 6.2 versus 5.3, 2.7  versus 4.7, 3.2 versus 5.1, 3.9 versus 4.9, and 4.6 versus 5.1,  respectively. Most patients who received the blocks felt they had  improved or greatly improved from baseline during the follow  up period. 
 
“This  study demonstrates that genicular nerve block is an effective short-term  therapy for pain management in people with knee osteoarthritis,” said  corresponding author Ernst M. Shanahan, BMBS,  MPH, MHPE, PhD, FAFOEM, FRACP, of Flinders University, in Australia.  “We think it may be a useful treatment option for this group of people,  in particular those waiting for, or wishing to defer surgery.”
 
Anifrolumab shows long-term promise in patients with lupus 
Type I  interferon (IFN) is a powerful immune activator that is present at high  levels in the majority of patients with lupus, an autoimmune disease. In Arthritis & Rheumatology, researchers report positive results from the first placebo-controlled long-term trial of anifrolumab—a  human monoclonal antibody that targets the type I IFN receptor—in patients with lupus. 
 
In the  long-term extension trial of two earlier phase 3 trials, patients  continued anifrolumab 300 mg, switched from anifrolumab 150 mg to 300  mg, or were re-randomized from placebo to either  anifrolumab 300 mg or continued placebo, administered every 4 weeks,  with all patients also receiving standard therapy. Anifrolumab was  administered as an intravenous infusion. 
 
Treatment  with anifrolumab was well tolerated and had an acceptable long-term  safety profile, while sustaining reduction in lupus disease activity and  reducing or eliminating the need for steroid  medications. 
 
“Managing  systemic lupus erythematosus is challenging, due to the complexity of  the disease itself, as well as from treatments like oral corticosteroids  that can reduce disease activity, but  also place a significant burden on patients when used in high doses  long-term,” said corresponding author Hussein Al-Mossawi, MD, PhD, of  AstraZeneca. “These new data from the TULIP extension trial—the longest  placebo-controlled clinical trial performed in  lupus to date—support the benefit-risk profile of anifrolumab seen in  previous trials, now over four years.”
