**Telitacicept Receives NMPA Conditional Approval for the Treatment of IgA Nephropathy in China**

*First and only approved BAFF/APRIL-targeting therapy for IgA nephropathy (IgAN)* 

*Approval based on positive interim Phase 3 TELIGAN results generated by collaborator RemeGen and recently published in The New England Journal of Medicine*

*IgAN marks the fourth indication approval for telitacicept* 

**BOSTON, Mass., June 8, 2026 (GLOBE NEWSWIRE)** – Vor Bio (Nasdaq: VOR), a clinical-stage biotechnology company transforming the treatment of autoimmune diseases, and RemeGen Co., Ltd., (HKEX: 9995, SHA: 688331) today announced that China's National Medicinal Products Administration (NMPA) has conditionally approved telitacicept for the treatment of adult patients with IgAN.

The conditional approval is supported by positive efficacy and safety data from RemeGen's completed Phase 2 trial (18C014) and Phase 3 TELIGAN trial (18C021 Part A) in IgAN. RemeGen independently developed telitacicept and is responsible for its development, regulatory approvals, and commercialization in China. Vor Bio holds exclusive rights to develop and commercialize telitacicept outside of Greater China.

"We are delighted to see telitacicept receive NMPA conditional approval in IgA nephropathy, representing an important achievement for the field and the first regulatory approval of a BAFF/APRIL-targeting therapy for IgAN," said Jean-Paul Kress, M.D., Chief Executive Officer and Chairman of Vor Bio. "We congratulate our collaborator RemeGen on the successful development, regulatory submission, and approval of telitacicept in China. Together with the positive Phase 3 TELIGAN results recently published in *The New England Journal of Medicine*, this milestone further validates the potential of dual BAFF/APRIL inhibition to address the underlying immunopathology of IgAN and supports our belief that telitacicept has the potential to become a foundational therapy across multiple autoimmune diseases globally."

The NMPA approval was supported by positive results from the Phase 3 TELIGAN trial, a multicenter, randomized, double-blind, placebo-controlled study evaluating telitacicept in adults with IgAN. The primary endpoint was change from baseline in urinary protein-to-creatinine ratio (UPCR) at Week 39.

In the primary analysis, patients treated with telitacicept 240 mg achieved a 59% reduction in UPCR from baseline at Week 39, corresponding to a 55% placebo-adjusted reduction. The study met its primary efficacy endpoint and demonstrated a favorable safety profile.

As previously reported in *The New England Journal of Medicine*, telitacicept treatment was also associated with encouraging preservation of kidney function. Estimated glomerular filtration rate (eGFR) remained largely stable through 39 weeks of treatment, while greater declines were observed in the placebo arm. Additional findings included reductions in circulating CD19+ B cells and serum immunoglobulin levels, including IgA, consistent with telitacicept's mechanism of action.

**About Telitacicept**

Telitacicept is a novel recombinant fusion protein designed to treat autoimmune diseases through dual inhibition of BLyS (BAFF) and APRIL - two cytokines essential to B cell and plasma cell

survival. This dual-target mechanism reduces autoreactive B cells and autoantibody production, key drivers of autoimmune pathology.

Telitacicept is approved in China for systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and generalized myasthenia gravis (gMG).

Vor Bio is advancing telitacicept in global Phase 3 trials in gMG and SjD to support potential regulatory approvals in the United States, Europe, and Japan.

**About IgA Nephropathy**

IgA nephropathy (IgAN) is one of the most common primary glomerular diseases worldwide and a leading cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD). It is characterized by IgA-containing immune complex deposition in the kidney, leading to inflammation, proteinuria, hypertension, and progressive loss of renal function. Up to 40% of patients progress to ESRD within 20 years of diagnosis, underscoring the significant unmet need for effective therapies. Current treatment approaches, including optimized blood pressure control, renin-angiotensin system blockade, and SGLT2 inhibitors, primarily slow disease progression but do not address the underlying immunopathology.

The prevailing scientific consensus is that overproduction of galactose-deficient IgA1 (Gd-IgA1) is a central driver of IgAN. BAFF and APRIL, two cytokines critical to B-cell survival and function, promote the production of Gd-IgA1 and its pathogenic antibodies.

**About Vor Bio**

Vor Bio is a clinical-stage biotechnology company transforming the treatment of autoimmune diseases. The Company is focused on rapidly advancing telitacicept, a novel dual-target fusion protein, through Phase 3 clinical development and potential commercialization to address serious autoantibody-driven conditions worldwide.

**Telitacicept Receives NMPA Approval for the Treatment of Sjögren's Disease in China**

*First regulatory approval for Sjögren's disease (SjD)*

*First and only approved therapy for SjD in China*

*Approval based on positive Phase 3 results generated by collaborator RemeGen demonstrating statistically significant and clinically meaningful improvements in both ESSDAI and ESSPRI*

*SjD marks the fifth indication approval for telitacicept* 

**BOSTON, Mass., June 8, 2026 (GLOBE NEWSWIRE)** – Vor Bio (Nasdaq: VOR), a clinical-stage biotechnology company transforming the treatment of autoimmune diseases, and RemeGen Co., Ltd., (HKEX: 9995, SHA: 688331) today announced that China's National Medicinal Products Administration (NMPA) has approved telitacicept for the treatment of adult patients with SjD.

The approval is supported by positive efficacy and safety data from RemeGen's Phase 3 clinical program in Sjögren's disease. RemeGen independently developed telitacicept and is responsible for its development, regulatory approvals, and commercialization in China. Vor Bio holds exclusive rights to develop and commercialize telitacicept outside of Greater China.

"We are thrilled to see telitacicept become the first and only approved therapy for Sjögren's disease in China, marking the first regulatory approval ever for this indication," said Jean-Paul Kress, M.D., Chief Executive Officer and Chairman of Vor Bio. "The approval represents a landmark moment for patients who have long lacked approved treatment options and reflects the strength of the clinical evidence supporting telitacicept. Notably, telitacicept is the only therapy to demonstrate statistically significant and clinically meaningful improvements in both ESSDAI and ESSPRI, underscoring its potential to address both systemic disease manifestations and the symptoms that matter most to patients. We congratulate RemeGen on this achievement and believe this fifth approved indication for telitacicept further reinforces its potential to become a foundational therapy across autoimmune diseases."

The NMPA approval was supported by a nationwide multicenter, randomized, double-blind, placebo-controlled Phase 3 study evaluating telitacicept in patients with SjD. The primary endpoint was change from baseline in EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI) score at Week 24.

In the primary analysis, patients treated with telitacicept achieved statistically significant reductions in ESSDAI score compared with placebo, with efficacy observed in both the 160 mg and 80 mg treatment groups and sustained through Week 48. Telitacicept also demonstrated clinically meaningful improvements in EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI), supporting benefit across both systemic disease activity and symptoms important to patients. The study met its primary efficacy endpoint and demonstrated a favorable safety profile.

**About Sjögren's Disease (formerly known as Sjögren's Syndrome)**

Sjögren's disease is a chronic autoimmune condition in which overactive B cells drive inflammation, damaging moisture-producing glands and, in many cases, other organs. Hallmark symptoms include dry eyes and dry mouth, alongside fatigue, pain, and systemic complications affecting the skin, lungs, kidneys, and nervous system. About one-third of patients develop significant extraglandular involvement, and the disease carries an elevated lymphoma risk, often leading to substantial impairment in daily life.

One of the most common rheumatic autoimmune diseases, Sjögren's remains underdiagnosed, with roughly half of cases unrecognized and women comprising the vast majority of patients. Despite its prevalence and burden, no systemic disease-modifying therapies exist; current care focuses on symptom management with incomplete relief.
