TRML Tourmaline Bio Inc

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 is hosting its Investor Day, beginning at 10 a.m. ET, during which it will outline progress across its pipeline and provide updates on its strategic priorities.

“We continue to be laser-focused on our development efforts for pacibekitug in order to maximize the potential of this program,” said Sandeep Kulkarni, MD, Co-Founder and Chief Executive Officer of Tourmaline Bio. “Today’s updates, including the over-enrollment of our TRANQUILITY trial, the expansion of our Cardiovascular Scientific Advisory Board, and the addition of a new indication, reflect the strength of our science, the caliber of our team, and our commitment to redefining standards of care for patients worldwide.”

Phase 2 TRANQUILITY Trial ProgressTourmaline today is announcing 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 patients have been enrolled in the Phase 2 TRANQUILITY trial, as compared to 120 patients originally anticipated. Tourmaline expects to report topline data from this 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 Tourmaline to be Phase 3-ready for ASCVD.

Expansion of Cardiovascular Scientific Advisory Board (CV SAB)Tourmaline has expanded its CV SAB with two new appointments:

• Deepak L. Bhatt, MD, MPH, MBA, FACC, FAHA, FESC, MSCAI joins as Chair of the Tourmaline CV SAB. Dr. Bhatt is the Director of the Mount Sinai Fuster Heart Hospital and the Dr. Valentin Fuster Professor of Cardiovascular Medicine at the Icahn School of Medicine at Mount Sinai in New York City. Dr. Bhatt has served as principal investigator for a number of groundbreaking cardiovascular clinical trials, bringing to the CV SAB decades of clinical trial expertise.
• Dipender Gill, MD, PhD is the CEO of Sequoia Genetics and a specialist in leveraging human genetic evidence for drug development. Dr. Gill adds deep translational insight to Tourmaline’s strategic focus.

Indication Expansion in Cardiovascular InflammationTourmaline has nominated 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 after topline results from the Phase 2 TRANQUILITY trial are reported in Q2 2025.

Update on Thyroid Eye Disease (TED) Development ProgramIn light of Tourmaline’s focus on cardiovascular inflammation, initiation of a Phase 3 trial in TED will be dependent upon results from the ongoing Phase 2b spiriTED trial. Topline data from the Phase 2b spiriTED trial are expected in the second half of 2025; Tourmaline expects to provide additional information on its future development plans in TED at that time.
