• Positive results from Phase 2/3 clinical studies supported by LRA affiliate Lupus Therapeutics point to potential new treatments
• Lupus Therapeutics' PALS Program helps overcome challenges of diverse lupus patient trial participation

SAN DIEGO, Nov. 6, 2023 /PRNewswire/ -- The Lupus Research Alliance (LRA), the largest non-governmental non-profit funder of lupus research worldwide, is pleased to announce results from more than 30 studies supported by the LRA and its clinical research affiliate Lupus Therapeutics will be presented at ACR Convergence 2023, the annual meeting of the American College of Rheumatology.

Studies will represent the full continuum of research that the LRA and Lupus Therapeutics support, from innovative foundational research to lupus clinical trials evaluating potential new treatments.

"The LRA and Lupus Therapeutics are extremely proud of the tremendous work we have supported that will contribute to the dynamic scientific dialogue at this important rheumatology meeting,' commented LRA President and CEO Albert T. Roy. "We also look forward to many presentations of exciting clinical research, including results from CAR-T cell therapy studies that built on pioneering work funded by the LRA and have the potential to shift the lupus treatment paradigm." 

FOUNDATIONAL RESEARCH FUNDED BY THE LRA

LRA-funded investigators will be presenting their recent breakthroughs across a broad spectrum of lupus research, including the impact of lupus on various organs such as the skin, kidney, and brain, the contribution of the gut microbiome to lupus, dysregulation of a variety of immune cell types underlying lupus, and more.

WORK CONDUCTED THROUGH THE LUPUS THERAPEUTICS PALS PROGRAM

Patient Advocates for Lupus Studies (PALS) is a peer support program that aims to improve participation in lupus clinical trials through increased education and availability of information about clinical trials. Individuals living with lupus who have clinical research act as peer educators, or PALs, to deliver educational sessions to others living with lupus. The PALS program was piloted from 2019-2021 and demonstrated significant increases in knowledge about, attitudes toward, and intentions to participate in lupus clinical trials among program participants.

About Lupus

Lupus is a chronic, complex autoimmune disease that affects millions of people worldwide. More than 90 percent of people with lupus are women, often striking during the childbearing years of 15-45. Blacks/African Americans, Hispanics, Asians, and Native Americans are at two to three times greater risk than Caucasians for developing lupus. In lupus, the immune system, meant to defend against infections, produces antibodies that mistakenly recognize the body's own cells as foreign, prompting other immune cells to attack and potentially damage organs such as the kidneys, brain, heart, lungs, blood, skin, and joints.
