NEW YORK, May 02, 2025 (GLOBE NEWSWIRE) — 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 first quarter of 2025 and outlined recent business highlights.
“We continue to see growing evidence and enthusiasm for the potential of addressing IL-6-driven cardiovascular inflammation through our discussions with cardiovascular disease experts, attendance at major medical conferences, and review of constantly emerging scientific literature,” said Sandeep Kulkarni, MD, Co-Founder and Chief Executive Officer of Tourmaline. “We look forward to the expected presentation of topline data from our Phase 2 TRANQUILITY trial of pacibekitug later in the second quarter. This readout has the potential to advance pacibekitug into the next stage of development within atherosclerotic cardiovascular disease, abdominal aortic aneurysm, and potentially other cardiovascular diseases.”
Clinical Highlights and Upcoming Milestones:
Cardiovascular Inflammation
- In December 2024, Tourmaline announced the over-enrollment of its Phase 2 TRANQUILITY trial, which evaluates quarterly and monthly subcutaneous dosing of pacibekitug in patients with elevated high-sensitivity C-reactive protein and chronic kidney disease. A total of 143 participants have been enrolled in the TRANQUILITY trial, as compared to 120 participants originally anticipated. Tourmaline remains on track to report topline data from the TRANQUILITY trial in the second quarter of 2025.
- The TRANQUILITY trial is the starting point of Tourmaline’s clinical development program for pacibekitug for the potential treatment of atherosclerotic cardiovascular disease (ASCVD) and other cardiovascular diseases. If successful, results from the TRANQUILITY trial are expected to position pacibekitug to be Phase 3-ready for ASCVD.
- At its Investor Day in December 2024, Tourmaline announced the nomination of abdominal aortic aneurysm (AAA) as an additional indication within its cardiovascular inflammation disease focus for pacibekitug. Tourmaline expects to provide additional details on a planned Phase 2 proof-of-concept trial in AAA in conjunction with the reporting of topline data from the TRANQUILITY trial.
Thyroid Eye Disease (TED)
- The Phase 2b spiriTED trial remains ongoing, and Tourmaline expects to report topline data from this trial in the second half of 2025.
- Tourmaline expects to provide additional information on its future development plans in TED after review of data from the Phase 2b spiriTED trial.
Publications and Presentations:
- Emil deGoma, MD, Tourmaline’s SVP of Medical Research was a contributing author and Dipender Gill, MD, PhD, a member of Tourmaline’s Cardiovascular Scientific Advisory Board, was the senior author on an original research manuscript entitled “Human Genetic Evidence to Inform Clinical Development of IL-6 Signaling Inhibition for Abdominal Aortic Aneurysm” that was published in the February 2025 issue of the American Heart Association’s Arteriosclerosis, Thrombosis, and Vascular Biology journal.
- In March 2025, representatives from Tourmaline presented a poster entitled “Real World Management Patterns and Outcomes in Thyroid Eye Disease: A Claims Analysis” at the North American Neuro-Ophthalmology Society 2025 Annual Meeting held in Tucson, Arizona.
- John Walsh, MD, Tourmaline’s Vice President, Head of Medical Affairs, Kristine Erickson, OD, PhD, Tourmaline’s Vice President and TA Head, Ophthalmology, Medical Research, and other representatives from Tourmaline were contributing authors to a publication entitled “The role of IL-6 in thyroid eye disease: An update on emerging treatments” that was published in the April 2025 issue of Frontiers in Ophthalmology.
First Quarter 2025 Financial Results:
Cash Position
- Cash, cash equivalents and investments were $275.3 million as of March 31, 2025, as compared to $294.9 million as of December 31, 2024. Tourmaline anticipates that its current cash, cash equivalents, and investments will provide cash runway into the second half of 2027, funding its operations through key pacibekitug data readouts in cardiovascular inflammation and TED as well as other pacibekitug development activities.
Operating Expenses
- Research and development expenses were $20.3 million for the first quarter of 2025, as compared to $11.4 million for the first quarter of 2024. The increase in research and development expenses was primarily driven by increased clinical trial expenses directly related to the TRANQUILITY and spiriTED trials, increased employee compensation costs attributable to additional headcount, increased routine toxicology study expenses, and increased consulting expenses.
- General and administrative expenses were $6.0 million for the first quarter of 2025, as compared to $6.1 million for the first quarter of 2024. The decrease in general and administrative expenses was primarily driven by decreased consulting expenses.
Net Loss
- Net loss was $23.0 million for the first quarter of 2025, resulting in a basic and diluted net loss per share of $0.89. Net loss was $13.3 million for the first quarter of 2024, resulting in basic and diluted net loss per share of $0.55.
- The increase in both net loss and net loss per share was attributable to increased operating expenses and Tourmaline’s overall growth from 2024 to 2025.

About Pacibekitug:
Pacibekitug is a long-acting, fully-human, anti-IL-6 monoclonal antibody with best-in-class potential and differentiated properties including a naturally long half-life, low immunogenicity, and high binding affinity to IL-6. Pacibekitug has been previously studied in approximately 450 participants, including patients with autoimmune disorders, across six completed clinical trials. Tourmaline is currently developing pacibekitug in atherosclerotic cardiovascular disease (ASCVD) and thyroid eye disease (TED) as its first two indications, with plans to expand into abdominal aortic aneurysm (AAA) and additional diseases in the future.
