SAN FRANCISCO and VANCOUVER, British Columbia, Nov. 13, 2026 (GLOBE NEWSWIRE) -- Jade Biosciences, Inc. (“Jade” or the “Company”) (Nasdaq: JBIO), a clinical-stage biotechnology company focused on developing best-in-class therapies for autoimmune diseases, today announced financial results for the third quarter ending September 30, 2026, and provided a corporate update.

“The third quarter marked another period of meaningful progress for Jade as we advanced each of our development programs toward important clinical milestones,” said Tom Frohlich, Chief Executive Officer of Jade. “We are preparing to initiate the Phase 3 EVERGREEN trial of JADE101 ahead of schedule, reflecting both our rapid execution and our continued conviction in JADE101’s potential best-in-class profile. We also expect to advance JADE301 into the clinic this quarter, which, alongside JADE101 and JADE201, will give us three clinical-stage programs heading into 2027. With multiple clinical catalysts expected across our pipeline next year, we see significant opportunities to further demonstrate the differentiated profiles of our programs and ultimately deliver meaningful new therapies for patients with autoimmune disease.”

Pipeline and Corporate Updates

JADE101: anti-APRIL monoclonal antibody for IgA nephropathy (IgAN)

• Jade expects to initiate EVERGREEN, a Phase 3 registrational trial of JADE101 in IgAN, in the fourth quarter of 2026, reflecting the Company’s rapid execution as JADE101 advances into registrational development. A Trial-in-Progress poster describing EVERGREEN was presented at the American Society of Nephrology (ASN) Kidney Week 2026.
• Enrollment in the Phase 2 JUNIPER trial of JADE101 in IgAN is ongoing, with interim data expected in the second quarter of 2027. A Trial-in-Progress poster describing JUNIPER was presented at ASN Kidney Week 2026.
  
  

JADE201: anti-BAFF-R monoclonal antibody for autoimmune diseases

• The Phase 1 clinical trial evaluating JADE201 in participants with rheumatoid arthritis is ongoing, with interim biomarker-rich data expected in 2027 to inform indication prioritization.
  
  

JADE301: anti-IFN-β monoclonal antibody for dermatomyositis

• Jade presented preclinical data at the 2026 European Academy of Dermatology and Venereology (EADV) Congress supporting the potentially differentiated profile of JADE301 in dermatomyositis. Key results included:
  • JADE301 demonstrated selective, high-affinity binding to IFN-β and greater functional potency than a dazukibart comparator in disease-relevant human cells.
  • Following subcutaneous (SC) administration in non-human primates, JADE301 demonstrated an approximately 25-day half-life and was well tolerated at all dose levels evaluated, supporting the potential for infrequent SC dosing.
• Jade expects to initiate a Phase 1 trial of JADE301 in healthy volunteers in the fourth quarter of 2026, with interim data anticipated in the second half of 2027.

Corporate

• Expanded Brad Dahms’ role and title to Chief Financial Officer and Chief Business Officer. Mr. Dahms will continue to oversee the Company's finance and investor relations functions and will now also lead business development and corporate strategy as Jade advances its pipeline toward multiple clinical readouts in 2027.
  
  

Third Quarter 2026 Financial Results

• Cash Position: As of September 30, 2026, Jade had cash, cash equivalents, and investments of $475.7 million. Based on its current operating plans, Jade believes that its existing cash, cash equivalents and investments will enable it to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2028.
  
  
• Research and Development (R&D) expenses: R&D expenses were $30.8 million for the third quarter ended September 30, 2026, an increase of $8.8 million compared to the third quarter of 2025, and included $3.6 million in stock-based compensation expense. R&D expenses increased primarily due to increased costs around chemistry, manufacturing and controls, clinical activity, and personnel-related costs and related stock-based compensation expense.
  
  
• General and Administrative (G&A) expenses: G&A expenses were $8.8 million for the third quarter ended September 30, 2026, an increase of $3.4 million compared to the third quarter of 2025, and included $3.5 million in stock-based compensation expense. The increase in G&A expenses was primarily due to higher personnel-related costs and related stock-based compensation expense.
  
  
• Net loss: Net loss totaled $35.1 million for the third quarter ended September 30, 2026, compared to $25.2 million for the third quarter of 2025. Net loss increased primarily due to higher R&D and G&A expenses, as described above.

The words “opportunity,” “potential,” “milestones,” “pipeline,” “can,” “goal,” “strategy,” “target,” “anticipate,” “achieve,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “plan,” “possible,” “project,” “should,” “will,” “would” and similar expressions (including the negatives of these terms or variations of them) may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements are based on current expectations and beliefs concerning future developments and their potential effects. There can be no assurance that future developments affecting Jade will be those that have been anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond Jade’s control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to: interim results of a clinical trial are not necessarily indicative of final results and one or more of the outcomes may materially change following more comprehensive reviews of the data, as follow-up on the outcome of any particular participant continues and as more participant or final data becomes available; predicted data for JADE101 may not be realized in actual clinical studies; the ongoing and planned clinical trials of JADE101, JADE201 and JADE301 and any other clinical trials may be delayed or may not demonstrate desirable efficacy or predicted performance; Jade’s planned JADE101 Phase 3 clinical trial may be delayed based on FDA feedback or requirements, as the FDA retains broad discretion to require additional clinical data for any product candidate prior to the conduct of a Phase 3 clinical trial or submission for regulatory approval; even if such Phase 3 trial is successful, it may not support regulatory approval; adverse events and safety signals may occur; Jade may experience unanticipated costs, difficulties or delays in the product development process; Jade’s product candidates may be delayed to a point where they are not commercially viable; clinical trial start up, enrollment or regulatory challenges may occur; challenges associated with Jade’s dependence on third-party vendors for the development, manufacture and supply of its product candidates may occur; Jade may use its capital resources sooner than expected; and the other risks, uncertainties and factors more fully described in Jade’s most recent filings with the Securities and Exchange Commission (including the Quarterly Report on Form 10-Q for the quarter ended June 30, 2026). Should one or more of these risks or uncertainties materialize, or should any of Jade’s assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. You should not place undue reliance on forward-looking statements in this communication, which speak only as of the date they are made and are qualified in their entirety by reference to the cautionary statements herein. Jade does not undertake or accept any duty to release publicly any updates or revisions to any forward-looking statements, except as required by law.
