## Exhibit 99.1

**Exhibit 99.1** 

**Jade Biosciences Outlines Key 2026 Objectives and Strategy to Advance Pipeline of Potentially Best-in-Class Monoclonal Antibodies Across Multiple Autoimmune Diseases Ahead of the 44th Annual J.P. Morgan Healthcare Conference** 

• *JADE101 Phase 1 healthy volunteer trial ongoing; biomarker-rich interim data expected in the first half of 2026* 

• *Phase 2 clinical trial of JADE101 in patients with IgA nephropathy expected to begin mid-2026; preliminary data anticipated in 2027* 

• *JADE201, a half-life extended afucosylated anti-BAFF receptor antibody, expected to advance into first-in-human study in rheumatoid arthritis patients in the second quarter of 2026; interim data anticipated in 2027* 

• *Third development candidate, JADE301, nominated; currently in preclinical development; Phase 1 clinical trial expected to commence in the first half of 2027* 

• *Approximately $336 million of cash, cash equivalents, and investments as of December 31 <sup>st</sup> , 2025 expected to provide runway into the first half of 2028* 

• *Company to present at the 44 <sup>th</sup> Annual J.P. Morgan Healthcare Conference on January 15, 2026, at 11:15 a.m. PT* 

**San Francisco and Vancouver, British Columbia** January 5, 2026 – Jade Biosciences, Inc. (the "Company" or "Jade") (Nasdaq: JBIO), a clinical-stage biotechnology company focused on developing best-in-class therapies for autoimmune diseases, today announced its 2026 strategic priorities, including anticipated milestones ahead of the 44th Annual J.P. Morgan Healthcare Conference, taking place January 12–15, 2026, in San Francisco, California.

"2026 is expected to be another year of rapid growth for Jade as we advance our pipeline across multiple clinical trials and transition toward late-stage development for our lead candidate, JADE101" said Tom Frohlich, Chief Executive Officer of Jade Biosciences. "With interim Phase 1 data and Phase 2 initiation anticipated for JADE101 in IgA nephropathy, the planned Phase 1 start of our anti-BAFF-R program, JADE201, and continued investment in discovery-stage antibody innovation, we are executing on a focused strategy to build a next-generation autoimmune company. Our programs are designed to deliver deeper, more durable efficacy with a lower treatment burden for patients. Backed by a strong balance sheet with runway expected to last into the first half of 2028, we enter the year poised to deliver meaningful benefit to patients, have impactful clinical catalysts, and drive long-term growth and value creation."

**Key Program Updates** 

***JADE101: Novel Anti-APRIL Monoclonal Antibody in Development for IgAN***

JADE101 is an investigational, fully human monoclonal antibody designed to selectively inhibit A Proliferation-Inducing Ligand (APRIL), a key driver of pathogenic IgA production in patients with IgA nephropathy (IgAN), a progressive autoimmune kidney disease that can lead to kidney failure. Currently

------

in Phase 1 testing in healthy volunteers, JADE101 has demonstrated ultra-high binding affinity in preclinical studies and is engineered for half-life extension, aiming to combine the disease-modifying efficacy of the anti-APRIL mechanism through a long dosing interval with patient-friendly subcutaneous dosing. Its favorable and differentiated preclinical safety, pharmacokinetic and pharmacodynamic profile in non-human primates supports the potential for infrequent dosing and a best-in-class therapeutic profile.

Jade is developing JADE101 with the goal of transforming the treatment paradigm for IgAN and other autoimmune diseases. The company believes selective anti-APRIL therapies are poised to become foundational treatments in IgAN, potentially moving to frontline therapy by delivering disease-modifying efficacy, including durable reductions in pathogenic IgA and proteinuria and stabilization of kidney function, without unnecessary immune suppression.

<u>Key upcoming anticipated JADE101 milestones:</u> 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Phase 1 interim results from the ongoing healthy volunteer study expected in the first half of 2026 are
anticipated to define dose and dose interval selection for Phase 2 and Phase 3 IgAN patient studies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Jade expects to initiate a Phase 2 clinical trial in patients with IgAN mid-2026, with preliminary data
anticipated in 2027.

***JADE201: Half-Life Extended, Afucosylated Anti-BAFF Receptor Monoclonal Antibody in Development for Autoimmune Diseases***

JADE201 is a half-life extended, enhanced effector function monoclonal antibody targeting the B-cell activating factor receptor (BAFF-R). JADE201 is designed to build on the differentiated dual mechanism of prior anti-BAFF-R antibodies to deplete B cells, while addressing limitations such as short half-life through the incorporation of half-life extension technology, with the goal of prolonging receptor coverage and enabling less frequent subcutaneous dosing. This approach has the potential to deliver deeper and more durable B-cell depletion than existing therapies, translating into enhanced efficacy and reduced treatment burden for patients.

<u>Key upcoming anticipated JADE201 milestones:</u> 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The randomized, placebo-controlled, single ascending dose trial will evaluate safety, tolerability,
pharmacokinetics, and pharmacodynamics, incorporating biomarker-rich endpoints such as BAFF-R occupancy, soluble BAFF levels, and B-cell subpopulation profiling.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• With its differentiated mechanism and engineering, JADE201 has broad potential across a range of autoimmune
diseases validated by BAFF-R biology.

**Broader Autoimmune Pipeline** 

<u>Key pipeline milestones:</u> 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Nominated development candidate, JADE301, an undisclosed antibody program.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• JADE301 is currently in preclinical testing and is expected to enter first-in-human study in the first half of 2027.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Further details on JADE301 are expected to be disclosed in the second half of 2026.

**Financial Update** 

Jade expects to report that its cash, cash equivalents and investments as of December 31, 2025 were approximately $336 million, which is expected to fund operations into the first half of 2028.

Jade has not yet completed its quarter- or year-end financial close process for the period ended December 31, 2025. This estimate of the Company's cash, cash equivalents and investments as of December 31, 2025 is preliminary, has not been audited and is subject to change upon completion of the company's financial statement closing procedures and the completion of the audit of the 2025 financial statements. Additional information and disclosure would be required for a more complete understanding of the Company's financial position and results of operations as of December 31, 2025. The Company's independent registered public accounting firm has not audited, reviewed or performed any procedures with respect to this preliminary result and, accordingly, does not express an opinion or any other form of assurance about it.
