New York, NY – August 8, 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 second quarter of 2024 and outlined recent business highlights.
“The second quarter of 2024 was another period of strong execution by Tourmaline, including the dosing of the first patient in the Phase 2 TRANQUILITY trial. This represents an important milestone in our pacibekitug clinical development plan, where multiple converging lines of evidence from human genetic studies, epidemiological studies, and mechanistic experiments support the therapeutic potential of IL-6 inhibition for millions of patients with cardiovascular diseases,” said Sandeep Kulkarni, MD, Co-Founder and Chief Executive Officer of Tourmaline. “Along with our ongoing clinical development efforts in TED, the TRANQUILITY trial provides us with two high-conviction paths to unlock major value creation as we approach key data readouts in 2025.”
Clinical Highlights and Upcoming Milestones:
TED
•The pivotal spiriTED Phase 2b trial in TED is currently enrolling, and Tourmaline continues to expect topline data in 2025.
•Tourmaline is on track to initiate a pivotal Phase 3 trial evaluating pacibekitug delivered subcutaneously every 8 weeks as first-line treatment for TED in the second half of 2024, with topline data expected in 2026.
Cardiovascular Inflammation
•In May 2024, Tourmaline initiated the clinical development of pacibekitug for cardiovascular diseases with the first patient dosed in its Phase 2 TRANQUILITY trial.
•At the American Society of Preventive Cardiology Annual Congress held in August 2024, Tourmaline presented a poster describing the rationale and design of the Phase 2 TRANQUILITY trial (“Evaluating TOUR006 in Participants with Chronic Kidney Disease and Elevated hs-CRP: Rationale and Design of the TRANQUILITY Phase 2 Study”).
•The TRANQUILITY trial is evaluating quarterly and monthly subcutaneous dosing of pacibekitug in patients with elevated high-sensitivity C-reactive protein (hs-CRP) and chronic kidney disease (CKD). Tourmaline continues to expect topline data from this trial in the first half of 2025.

•If successful, results from the Phase 2 TRANQUILITY trial are expected to position Tourmaline to be Phase 3-ready in 2025 for pacibekitug in cardiovascular diseases.
Other Corporate Highlights:
•In June 2024, Tourmaline announced the promotion of Ryan Robinson, CPA, to Chief Financial Officer and Treasurer. Mr. Robinson most recently held the role of Vice President, Finance and Controller at Tourmaline, in addition to serving as Tourmaline’s Interim Chief Financial Officer and Treasurer since October 2023.
•Also in June 2024, Tourmaline was added to the Russell 2000® Index and the broad-market Russell 3000® Index as part of the Russell indexes annual reconstitution.
Second Quarter 2024 Financial Results:
Cash Position
•Cash, cash equivalents and investments were $334.4 million as of June 30, 2024, as compared to $203.0 million as of December 31, 2023. Tourmaline anticipates that its current cash, cash equivalents and investments will provide cash runway into 2027, funding key pacibekitug data readouts in TED and cardiovascular disease and the opportunity to expand development efforts into additional indications.
Operating Expenses
•Research and development expenses were $15.7 million for the second quarter of 2024, as compared to $14.5 million for the second quarter of 2023. The increase in research and development expenses was primarily driven by employee compensation costs attributable to increased headcount as well as costs related to the spiriTED and TRANQUILITY trials. Research and development expenses incurred during the second quarter of 2023 included $8.8 million of non-cash expense related to the issuance of additional shares to Pfizer Inc. (Pfizer) pursuant to an anti-dilution provision within the License Agreement between Tourmaline and Pfizer.
•General and administrative expenses were $6.2 million for the second quarter of 2024, as compared to $1.9 million for the second quarter of 2023. The increase in general and administrative expenses was primarily driven by employee compensation costs attributable to increased headcount, increased consulting expenses, including recruiting, commercial planning and other services, and increased professional service fees.
Net Loss
•Net loss was $17.5 million for the second quarter of 2024 and $16.1 million for the second quarter of 2023, resulting in basic and diluted net loss per share of $0.68 and $16.29, respectively.
•The increase in net loss was attributable to increased operating expenses and the overall growth of Tourmaline throughout 2023 and into 2024. The decrease in net loss per share was attributable to the issuance of additional shares of common stock in conjunction with Tourmaline’s reverse merger and private placement that were completed in October 2023 as well as the underwritten follow-on public offering completed by Tourmaline in January 2024.
