Zura Bio Limited (Nasdaq: ZURA) (“Zura Bio”), a clinical stage, multi-asset immunology company developing novel dual-pathway antibodies for autoimmune and inflammatory diseases, today reported its first quarter 2024 financial results, and recent business highlights.

"Our recent financial and business highlights demonstrate how we continue to strengthen the company for future success. Our leadership additions and oversubscribed $112.5 million private placement lay the groundwork for operational success and provide cash runway through 2027. The private placement by leading life sciences investors emphasizes the confidence in our pipeline of novel, dual-pathway antibodies for autoimmune and inflammatory diseases,” stated Robert Lisicki, CEO of Zura Bio. “We remain focused on the design and on-time execution of our tibulizumab development program with a goal to introduce best in-class therapies to people living with SSc and HS. These are two underserved therapeutic areas where patients may realize the benefit of tibulizumab’ s dual-pathway approach, targeting IL-17 and BAFF.”

RECENT BUSINESS AND FINANCIAL HIGHLIGHTS

Raised gross proceeds of approximately $112.5 million in an oversubscribed private placement, which are expected to:

• Support the accelerated development of tibulizumab, including the planned Phase 2 clinical trial in SSc, and the initiation of a Phase 2 trial evaluating the dual-pathway antibody for the treatment of HS.
• Extend cash runway through 2027.

Appointed new members to the Executive Management team and Board who bring extensive experience and proven track records in drug and business development.

• In April 2024, Robert Lisicki was appointed Chief Executive Officer, succeeding founding CEO Someit Sidhu, M.D., who remains actively involved in the company as a Director.
• In January 2024, Dr. Kiran Nistala was appointed Executive Vice President of Development and Chief Medical Officer.

Cash and cash equivalents: Cash and cash equivalents were $89.8 million as of March 31, 2024, as compared to $99.8 million as of December 31, 2023. Zura Bio anticipates that with the recent private placement factored in, its cash and cash equivalents are sufficient to fund planned operations through 2027.

Research and Development (R&D) expenses: R&D expenses were $3.6 million for the first quarter of 2024, a decrease of $1.3 million compared to $4.9 million for the same period in 2023. The decrease was primarily due to $4.1 million in share-based compensation related to license agreements. The decrease was offset by $1.4 million in compensation for personnel, including share-based compensation as well as $1.4 million for consulting services and manufacturing of our product candidates.

General and Administrative (G&A) expenses: G&A expenses were $4.8 million for the first quarter, an increase of $1.9 million compared to the $2.8 million for the same period in 2023. The increase was primarily due to an increase of $1.6 million in compensation for personnel including share-based compensation as well as an increase of $0.4 million in professional services and other daily operations.

Net loss: Net loss for the first quarter of 2024 was $7.7 million or compared to $9.6 million for the same period in 2023.
