Zura Bio Reports First Quarter 2026 Financial Results and Recent Corporate Updates

Key Terms

phase 2 medical

Phase 2 is the mid-stage clinical trial where a new drug or treatment is tested in a larger group of patients to see if it works and to keep checking safety after initial human testing. Think of it as a field test that proves whether a product actually delivers its promised benefit. Investors watch Phase 2 closely because its results strongly influence a medicine’s chances of reaching the market, the size of its potential sales, and the company’s valuation.

bispecific antibody medical

A bispecific antibody is a specially designed protein that can attach to two different targets at the same time. Think of it as a custom-made connector that brings two things together—such as a disease cell and an immune system component—helping the body fight illnesses more effectively. For investors, understanding bispecific antibodies is important because they represent innovative therapies that could lead to new treatments and potentially lucrative market opportunities.

interleukin-17 (IL-17) medical

Interleukin-17 (IL-17) is a small protein made by immune cells that acts like a messenger or alarm, telling the body to mount an inflammatory response against infections or perceived threats. For investors, IL-17 matters because drugs that block or modify its activity can treat autoimmune and inflammatory diseases, influence clinical trial outcomes, and affect the commercial prospects and regulatory risk of biotech and pharmaceutical companies.

b-cell activating factor (BAFF) medical

A B‑cell activating factor (BAFF) is an immune system protein that helps B cells — the white blood cells that make antibodies — survive and multiply; think of it like a fertilizer that helps a specific garden of immune cells grow. Investors watch BAFF because drugs that block or modify it can treat autoimmune diseases or affect cancer and vaccine responses, so BAFF‑targeting therapies, trial results, or regulatory changes can influence a company’s value.

hidradenitis suppurativa medical

A chronic skin disease marked by recurring, painful lumps and tunnels under the skin that often leak and leave scars; it behaves like a slow-burning, recurring infection in areas with many sweat glands. For investors, it matters because the condition has few consistently effective treatments and causes long-term healthcare use, making successful new drugs, devices, or diagnostics potentially high-value opportunities while also carrying clinical-trial, regulatory and reimbursement risks.

systemic sclerosis medical

Systemic sclerosis is a chronic autoimmune disease where the body's repair system overreacts, causing hardening and tightening of skin and internal organs much like scar tissue spreading beyond a wound. It matters to investors because it creates a clear medical need for new treatments, influences the size and urgency of clinical trials, and affects regulatory scrutiny, pricing power, and long-term healthcare costs tied to any therapy or diagnostic that proves effective.

pre-funded warrants financial

Pre-funded warrants are financial instruments that give investors the right to purchase a company's stock at a set price, but with most or all of the purchase price paid upfront. They function like a coupon or gift card for stock, allowing investors to buy shares later at a fixed price, which can be beneficial if they want to avoid future price increases. This makes them important for investors seeking flexibility and certainty in their investment plans.

HENDERSON, Nev.--(BUSINESS WIRE)-- Zura Bio Limited (Nasdaq: ZURA) (“Zura”), a clinical-stage biotechnology company developing novel and differentiated medicines to meaningfully improve the lives of patients with serious and debilitating autoimmune and inflammatory diseases, today announced financial results for the first quarter ended March 31, 2026, and provided recent corporate updates.

“We entered the second quarter with a strengthened balance sheet and strengthened team, reflecting growing conviction in bispecific approaches and increased appreciation for IL‑17 and BAFF biology” said Sandeep Kulkarni, M.D., Chief Executive Officer of Zura. “We believe we are well positioned—operationally, financially, and scientifically—as we approach anticipated tibulizumab readouts starting later this year.”

PROGRAM UPDATES

Tibulizumab (ZB‑106)

During the first quarter of 2026, Zura continued to advance its two ongoing Phase 2 studies of tibulizumab, a bispecific antibody designed to neutralize interleukin-17 (IL-17) and B-cell activating factor (BAFF), key mediators of inflammation and fibrosis.

• TibuSHIELD (HS): The Phase 2 clinical study evaluating tibulizumab in adult participants with HS is ongoing, with enrollment of approximately 225 patients on track. Topline data are anticipated in the fourth quarter of 2026.
• TibuSURE (SSc): The Phase 2 clinical study evaluating tibulizumab in adult participants with SSc is ongoing, with enrollment of approximately 80 patients on track. Topline data are anticipated in the first half of 2027.

Additionally, Zura is conducting a disciplined evaluation of potential new indications for tibulizumab.

Additional Clinical Stage Product Candidates

In addition to tibulizumab, Zura is continuing its evaluation of potential development approaches for torudokimab (ZB‑880) and crebankitug (ZB‑168), informed by current clinical and translational evidence and ongoing assessment of the evolving competitive landscape.

CORPORATE HIGHLIGHTS

In January 2026, Zura appointed Sandeep Kulkarni, M.D., as Chief Executive Officer. In February 2026, Zura appointed Mark Eisner, M.D., M.P.H., and Ajay Nirula, M.D., Ph.D., to its Board of Directors. Dr. Eisner, is a seasoned biotechnology executive with over 25 years of leadership in clinical development and immunology and recently served as Executive Vice President and Chief Medical Officer of Vir Biotechnology.

He previously served as Senior Vice President and Immunology Therapeutic Area Head at Eli Lilly.

In February 2026, Zura closed an underwritten public offering of Class A ordinary shares and pre-funded warrants to purchase Class A ordinary shares, resulting in gross proceeds of approximately $144 million, before deducting underwriting discounts, commissions, and offering expenses. The proceeds are expected to support continued advancement of the Company’s pipeline and broader strategic development initiatives.

FIRST QUARTER 2026 FINANCIAL RESULTS

Cash Position

As of March 31, 2026, Zura had cash and cash equivalents of $225.6 million. Zura expects that its existing cash and cash equivalents are sufficient to support planned operations through at least the end of 2028.

Research and Development (R&D) Expenses

R&D expenses were $14.7 million for the first quarter of 2026, compared to $10.5 million for the first quarter of 2025. The increase was primarily driven by the continued advancement of Zura’s Phase 2 tibulizumab clinical programs.

General and Administrative (G&A) Expenses

G&A expenses were $10.8 million for the first quarter of 2026, compared to $8.8 million for the first quarter of 2025. The increase was primarily due to an increase in compensation expense, including share-based compensation and professional fees to support the Company’s growth and advancement of its clinical programs.

Net Loss

Net loss for the first quarter of 2026 was $24.2 million, or $0.22 per share, compared to $17.4 million, or $0.19 per share, for the same period in 2025.
