New York, NY – March 19, 2024 – Tourmaline Bio, Inc. (Tourmaline) (NASDAQ: TRML), a late-stage clinical biotechnology company developing transformative medicines to dramatically improve the lives of patients with life-altering immune and inflammatory diseases, today announced its financial results for the fourth quarter and year ended December 31, 2023 and outlined recent business highlights.
“2023 was a transformational year for Tourmaline. We became a public company and continued our efforts to lead an IL-6 renaissance with TOUR006, which we believe can achieve a best-in-class profile by providing a long-acting, patient-friendly treatment through low-volume subcutaneous injections,” said Sandeep Kulkarni, MD, Co-Founder and Chief Executive Officer of Tourmaline. “With the support of our expanding team, the clinical and patient communities, and our shareholders, we look forward to executing on our two strategic paths. We aim to harness the exciting and emerging insights in the IL-6 field towards addressing significant unmet medical needs in TED, ASCVD, and other autoantibody and inflammation-driven diseases.”
Clinical Highlights and Upcoming Milestones:
Tourmaline is pursuing development of TOUR006 in two areas of high unmet need: FcRn+ and cardiovascular inflammation.
FcRn+
•Tourmaline believes that TOUR006, a long-acting, fully-human, anti-IL-6 monoclonal antibody, can potentially deliver substantial therapeutic benefit to address a wide range of autoantibody-driven disorders, including a more durable response and patient-friendly administration than therapies currently on the market or in clinical development by others.
•The pivotal spiriTED Phase 2b trial in TED is currently enrolling, and Tourmaline continues to expect topline data in the first half of 2025.
•Tourmaline plans to accelerate the initiation of a pivotal Phase 3 trial evaluating subcutaneous TOUR006 every 8 weeks as first-line treatment for TED in 2024, with topline data expected in 2026.

•Tourmaline continues to explore additional indications with significant unmet medical need under its FcRn+ strategic path.
Cardiovascular Inflammation
•During 2023, Tourmaline reached alignment with the U.S. Food and Drug Administration (FDA) on the clinical development program of TOUR006 in ASCVD, and Tourmaline received clearance for the related IND in March 2024.
•Tourmaline plans to commence a Phase 2 trial evaluating quarterly subcutaneous dosing of TOUR006 in patients with elevated cardiovascular risk in the first half of 2024. Data from this Phase 2 trial are expected in the first half of 2025.
Other Corporate Highlights:
•In October 2023, Tourmaline become a publicly-traded company via reverse merger with Talaris Therapeutics, including a concurrent private placement of $75.0 million.
•In December 2023, Tourmaline expanded its Board of Directors with the appointment of Dr. Clay Siegall as Chairman.
•Tourmaline also continued to expand its executive leadership team during 2023, including the appointments of Gerhard Hagn as SVP, Head of Commercial and Business Development and Dr. Emil deGoma as SVP, Medical Research.
•In December 2023, Tourmaline was added to the NASDAQ Biotechnology Index (NASDAQ: NBI).
•In January 2024, Tourmaline completed an underwritten follow-on public offering of its common stock, which included the full exercise of the underwriters' option to purchase additional shares, resulting in gross proceeds of $172.5 million. Net proceeds were $161.3 million after deducting underwriting discounts and offering expenses.
Fourth Quarter and Full Year 2023 Financial Results:
Cash Position
•Cash, cash equivalents and investments were $203.0 million as of December 31, 2023, as compared to $8.3 million as of December 31, 2022. Tourmaline anticipates that its current cash, cash equivalents and investments as of the date hereof, which includes $161.3 million of net proceeds received from the January 2024 underwritten public offering, will provide cash runway into 2027, funding key TOUR006 data readouts in TED and cardiovascular disease and the opportunity to expand development efforts into additional indications.
Research and Development Expenses
•Research and development expenses were $8.0 million for the fourth quarter of 2023, as compared to $3.8 million for the fourth quarter of 2022.
•Research and development expenses were $32.4 million for the full year ended December 31, 2023, as compared to $17.5 million for the full year ended December 31, 2022.
•The increase in research and development expenses for both periods was primarily driven by employee compensation costs attributable to increased headcount, costs associated with the manufacture of drug substance and drug product for Tourmaline’s clinical trials, and clinical trial costs related to the spiriTED trial.

General and Administrative Expenses
•General and administrative expenses were $6.9 million for the fourth quarter of 2023, as compared to $1.1 million for the fourth quarter of 2022.
•General and administrative expenses were $13.0 million for the full year ended December 31, 2023, as compared to $2.2 million for the full year ended December 31, 2022.
•The increase in general and administrative expenses for both periods was primarily driven by employee compensation costs attributable to increased headcount, increased recruiting and commercial consulting expenses, and increased professional service fees.
Net Loss
•Net loss was $12.9 million for the fourth quarter of 2023 and $4.9 million for the fourth quarter of 2022, resulting in basic and diluted net loss per share of $0.81 and $5.51, respectively.
•Net loss was $42.1 million for the full year ended December 31, 2023 and $19.7 million for the full year ended December 31, 2022, resulting in basic and diluted net loss per share of $8.87 and $22.46, respectively.
•The increase in net loss for both periods was attributable to increased operating expenses and the overall growth of Tourmaline during 2023 as compared to 2022. The decrease in net loss per share for both periods was attributable to the issuance of additional shares of common stock in conjunction with the reverse merger and private placement that were completed in October 2023.
