SAN FRANCISCO and VANCOUVER, British Columbia, March 06, 2026 (GLOBE NEWSWIRE) -- Jade Biosciences, Inc. (“Jade” or the “Company”) (Nasdaq: JBIO), a biotechnology company focused on developing best-in-class therapies for autoimmune diseases, today announced financial results for the fourth quarter and full year ending December 31, 2025, and provided a corporate update.

Tom Frohlich, Chief Executive Officer of Jade Biosciences, commented: “We closed 2025 with strong momentum, having initiated the JADE101 Phase 1 healthy volunteer study, continued to advance JADE201 toward the clinic, and further strengthened our team and balance sheet. As we look ahead, our focus is on delivering interim, biomarker-rich Phase 1 data for JADE101, initiating the Phase 2 clinical trial in IgA nephropathy, and starting first-in-human dosing for the Phase 1 clinical trial of JADE201. With multiple clinical milestones approaching and cash runway expected to extend into the first half of 2028, we are well positioned to execute on our near-term priorities while continuing to build a differentiated pipeline with the goal of delivering best-in-class, disease-modifying autoimmune therapies to patients.”

Pipeline and Corporate Updates

JADE101: potentially best-in-class selective anti-APRIL monoclonal antibody for IgA nephropathy (IgAN)

• Phase 1 biomarker-rich interim results from the ongoing healthy volunteer study are expected in the second quarter of 2026 and are anticipated to define dose and dose interval selection for IgAN patient studies.
  • Jade expects to evaluate the Phase 1 clinical data and explore opportunities to accelerate the development of JADE101.
• Jade expects to initiate a Phase 2 clinical trial in patients with IgAN mid-2026, with preliminary data anticipated in 2027.
  
  

JADE201: potentially best-in-class anti-BAFF-R monoclonal antibody for autoimmune diseases

• A first-in-human study initially evaluating JADE201 in patients with rheumatoid arthritis is expected to begin in the second quarter of 2026, with interim data anticipated in 2027. With its differentiated mechanism and engineering, JADE201 has broad potential across a range of autoimmune diseases validated by BAFF-R biology.
  
  

JADE301: undisclosed antibody program for autoimmune diseases

• JADE301, an undisclosed antibody program, is expected to enter a first-in-human clinical trial in the first half of 2027. Further details on JADE301 are expected to be disclosed in the second half of 2026.

• In the fourth quarter, Jade completed two private placement financings resulting in gross proceeds of approximately $180 million, with participation from new and existing leading healthcare investors.
  
  

Fourth Quarter and Full Year 2025 Financial Results

• Cash Position: As of December 31, 2025, Jade had cash, cash equivalents, and investments of $336.2 million. Based on its current operating plans, Jade believes that its existing cash will enable it to fund its operating expenses and capital expenditure requirements into the first half of 2028.

R&D expenses increased primarily due to higher personnel-related costs as the Company builds out the internal R&D function as well as increased costs around chemistry, manufacturing and controls and early clinical activity.
