YANTAI, China I April 8, 2025 I On April 8, 2025 (UTC-7), impressive results of the Phase 3 clinical trial (NCT05737160) evaluating the efficacy and safety of Telitacicept (synonym: RC18; brand name: 泰爱 ® ) in patients with generalized myasthenia gravis (gMG) were presented during the Late-Breaking Science Session at the American Academy of Neurology (AAN) Annual Meeting 2025 in San Diego, CA. According to the presented data, among the participants in the Telitacicept 240 mg group, 98.1% of the patients demonstrated a ≥ 3-point reduction in Myasthenia Gravis Activities of Daily Living (MG-ADL) score and 87% of the patients demonstrated a ≥ 5-point reduction in Quantitative Myasthenia Gravis (QMG) score at Week 24. With the highest MG-ADL response rate among all drugs for gMG with phase 3 studies reported to date, Telitacicept will provide an important new treatment option gMG. Telitacicept is a novel fusion protein targeting both BlyS and APRIL independently designed and developed by RemeGen Co.,Ltd. (“RemeGen”). The multicenter, randomized, double-blind, placebo-controlled phase 3 clinical trial was conducted in China (NCT05737160) and led by Professor Jian Yin of Beijing Hospital. A total of 114 gMG patients with baseline MG-ADL score ≥6 and QMG score ≥8 were enrolled in the study, with 57 patients in the Telitacicept 240 mg group and the placebo group respectively. The study consisted of a 24-week double-blind treatment stage and an open-label treatment stage. The presented results herein were from the double-blind treatment study. The data showed that ‌Telitacicept‌ achieved ‌sustained and significant improvement‌ in clinical outcomes for patients with gMG, ‌with a favorable safety profile： The principal investigator Prof. Yin Jian of Beijing Hospital said “Telitacicept demonstrated rapid and significant clinical improvement in the phase 3 trial, and was well tolerated. Its dual-targeting mechanism not only inhibits abnormal B cells and plasma cells thoroughly and reduces the level of pathogenic antibodies, but also effectively slows down disease progression in the long term, and reduces steroid dosage as symptoms improve, providing a more precise, efficient, persistent, and safer option for gMG treatment.” Dr. Jianmin Fang, CEO of RemeGen, said “The phase 3 data of Telitacicept for MG is clinically meaningful. There is a large unmet medical need in MG because the disease presents significant threat to patients’ health and life-span. This breakthrough means that we have an new, effective treatment for MG as Telitacicept can significantly improve patients’ symptoms and bring long term benefits to MG patients. We look forward to working with global experts and scholars to overcome more complex autoimmune diseases and benefit more patients.” MG is an autoimmune disease caused by neuromuscular junction transmission disorders. It is characterized by fatigue and fluctuations in symptoms, long treatment cycles and high recurrence rate. More than 85% of patients develop to gMG within 24 months of onset. According to Frost & Sullivan report, there are about 1.2 million MG patients worldwide, including about 220,000 patients in China. At present, there is a great unmet medical demand. The newly disclosed “best-in-class” data mark a breakthrough achievement of Chinese innovative drugs in the field of neuroimmunology. Currently, the BLA of Telitacicept for the treatment of gMG has been accepted by the Center for Drug Evaluation (CDE) of China’s National Medical Products Administration, and it is expected to be approved in China in the second quarter of this year. Meanwhile, RemeGen is advancing a global multicenter Phase 3 trial of Telitacicept for the treatment of gMG, aiming to validate the efficacy and safety of Telitacicept in a wider patient population, and to provide a superior treatment option for gMG patients worldwide.

The data showed that ‌Telitacicept‌ achieved ‌sustained and significant improvement‌ in clinical outcomes for patients with gMG, ‌with a favorable safety profile： Telitacicept demonstrated significant improvements‌ in MG-ADL and QMG scores after 4 weeks' treatment compared to placebo. At Week 24, change in MG-ADL was -5.74 and -0.91 with Telitacicept and placebo group, respectively. 98.1% and 12.0% of Telitacicept and placebo group patients had ≥3-point reduction in MG-ADL, respectively. The MG-ADL scale quantifies the impact of MG symptoms on daily life quality, focusing on patients' subjective experience and daily function. These data showed that patients treated with Telitacicept achieved ‌clinically meaningful improvement‌‌. At Week 24, change in QMG was -8.66 and -2.27 with Telitacicept and placebo group, respectively. 87.0% and 16.0% of Telitacicept and placebo group patients had ≥ 5-point reduction in QMG, respectively. The QMG score assesses the strength and endurance of the whole body muscle group, focusing on objective measurement. These data demonstrated that patients treated with Telitacicept‌ achieved ‌clinically meaningful reductions in disease severity. There is a strong correlation between MG-ADL and QMG in evaluating treatment response, and the combination of MG-ADL and QMG can comprehensively reflect the disease severity. Sustained improvement: MG-ADL and QMG scores continued to decline over time in the Telitacicept group, with peak improvement at the last reported observation, Week 24. Telitacicept was well tolerated during the treatment, with an overall adverse event (AE) incidence similar to that in the placebo group and an incidence of infection-related AEs lower than that in the placebo group (45.6% vs. 59.6%). The principal investigator Prof. Yin Jian of Beijing Hospital said "Telitacicept demonstrated rapid and significant clinical improvement in the phase 3 trial, and was well tolerated.

On track to announce primary endpoint result from ORIGIN 3 trial this quarter (2Q 2025)U.S. FDA BLA submission for accelerated approval planned for 2H 2025 BRISBANE, Calif., April 03, 2025 (GLOBE NEWSWIRE) -- Vera Therapeutics, Inc. (Nasdaq: VERA), a late clinical-stage biotechnology company focused on developing and commercializing transformative treatments for patients with serious immunological diseases, today announced that it has completed full enrollment in the pivotal ORIGIN Phase 3 trial of atacicept in patients with IgA Nephropathy (IgAN). “We are grateful for the IgAN community’s strong interest in the clinical development of atacicept that helped drive us towards completing full enrollment in the ORIGIN 3 trial with a total of 431 participants. Complete enrollment represents another key milestone on the path to potential approval of the first B cell modulator targeting both BAFF and APRIL for IgAN,” said Marshall Fordyce, M.D., Founder and CEO of Vera Therapeutics. “We anticipate the 36-week primary efficacy endpoint data from the trial this quarter, which supports our planned Biologics License Application for an accelerated approval to the U.S. FDA in the second half of 2025. ORIGIN 3 follows the positive long-term results from the ORIGIN Phase 2b trial that demonstrated sustained and substantial reductions in Gd-IgA1, hematuria and proteinuria, and showed stabilized kidney function through 96 weeks, positioning atacicept as a potential best-in-class IgAN therapy. Pending the submission and thorough FDA review of the BLA, we would look forward to a potential PDUFA date and commercial launch in 2026.” The ORIGIN 3 trial (NCT04716231) is a global, multicenter, randomized, double-blind, placebo-controlled Phase 3 trial evaluating the safety and efficacy of atacicept in patients with IgAN who have persistent proteinuria and remain at high risk of disease progression. Participants are randomized 1:1 to at-home self-administered once-weekly subcutaneous injections of atacicept 150 mg or placebo for a 104-week double-blind period, followed by a 52-week open-label extension. The primary efficacy endpoint is the change in proteinuria as evaluated by urine protein to creatinine ratio (UPCR) through 36 weeks in an interim analysis of at least 200 participants. The key secondary efficacy endpoint is change in kidney function as measured by estimated glomerular filtration rate (eGFR) through 104 weeks in the full study population. For more information about the ORIGIN 3 clinical trial, please visit http://www.clinicaltrials.gov. In addition, the Company is currently conducting the ORIGIN Extend trial, which provides extended access to atacicept for participants from the ORIGIN Phase 2b or Phase 3 trials until commercial availability in their region, and captures longer-term safety and efficacy data. About Atacicept Atacicept is an investigational recombinant fusion protein that contains the soluble transmembrane activator and calcium-modulating cyclophilin ligand interactor (TACI) receptor that binds to the cytokines B-cell activating factor (BAFF) and A PRoliferation-Inducing Ligand (APRIL). These cytokines are members of the tumor necrosis factor family that promote B-cell survival and autoantibody production associated with certain autoimmune diseases, including IgAN and lupus nephritis. The Phase 2b ORIGIN clinical trial of atacicept in IgAN met its primary and key secondary endpoints, with statistically significant and clinically meaningful proteinuria reductions and stabilization of eGFR versus placebo through 36 weeks. The safety profile during the randomized period was comparable between atacicept and placebo. Through 96 weeks, atacicept demonstrated further reductions in Gd-IgA1, hematuria, and proteinuria, as well as stabilization of eGFR reflecting a profile consistent with that of the general population without IgAN. Atacicept has received FDA Breakthrough Therapy Designation for the treatment of IgAN, which reflects the FDA’s determination that, based on an assessment of data from the Phase 2b ORIGIN clinical trial, atacicept may demonstrate substantial improvement on a clinically significant endpoint over available therapies for patients with IgAN. Vera believes atacicept is positioned for best-in-class potential, targeting B cells to reduce autoantibodies and having been administered to more than 1,500 patients in clinical studies across different indications. About VeraVera Therapeutics is a late clinical-stage biotechnology company focused on developing treatments for serious immunological diseases. Vera’s mission is to advance treatments that target the source of immunological diseases in order to change the standard of care for patients. Vera’s lead product candidate is atacicept, a fusion protein self-administered as a subcutaneous injection once weekly that blocks both B-cell Activating Factor (BAFF) and A PRoliferation-Inducing Ligand (APRIL), which stimulate B cells to produce autoantibodies contributing to certain autoimmune diseases, including IgAN, also known as Berger’s disease, and lupus nephritis. In addition, Vera is evaluating additional diseases where the reduction of autoantibodies by atacicept may prove medically useful. Vera is also developing MAU868, a monoclonal antibody designed to neutralize infection with BK virus (BKV), a polyomavirus that can have devastating consequences in certain settings such as kidney transplant. Vera retains all global developmental and commercial rights to atacicept and MAU868. Vera also holds an exclusive license agreement with Stanford University for a novel, next generation fusion protein targeting BAFF and APRIL, known as VT-109, with wide therapeutic potential across the spectrum of B cell mediated diseases.
