WATERTOWN, Mass. - Tectonic Therapeutic, Inc. (NASDAQ: TECX), a clinical-stage biotechnology company, announced successful Phase 1a trial results for TX45, a drug candidate for treating Group 2 Pulmonary Hypertension in Heart Failure with Preserved Ejection Fraction (PH-HFpEF). The trial demonstrated favorable safety, tolerability, and pharmacokinetic/pharmacodynamic (PK/PD) profiles, setting the stage for Phase 2 trials.
TX45, an Fc-relaxin fusion protein targeting the RXFP1 receptor, is designed to mimic the vasodilative and anti-fibrotic effects of the hormone relaxin. The Phase 1a trial assessed single ascending doses of TX45 in healthy volunteers, revealing minimal adverse events and no evidence of immune-mediated clearance. These results confirmed the drug's potential for further clinical development.
The trial's PK/PD analysis was instrumental in selecting dosing regimens for the upcoming global Phase 2 randomized trial, which will evaluate TX45's effects on patients with PH-HFpEF over six months. Tectonic has initiated screening for the Phase 2 APEX clinical trial, with topline results anticipated in 2026.
Currently, there are no commercialized treatments for the estimated 600,000 U.S. patients with combined Group 2 PH and HFpEF. Tectonic's progress, including the FDA's clearance of their Investigational New Drug application for TX45, marks a significant step towards addressing this unmet medical need.
In addition to the Phase 1a findings, Tectonic is conducting a Phase 1b hemodynamic proof-of-concept trial, escalating to the highest dose of TX45 (3 mg/kg) based on its favorable tolerability profile. This trial is evaluating the acute hemodynamic effects of TX45 in PH-HFpEF patients, with topline results expected in the second quarter of 2025.
Tectonic's focus on G-protein coupled receptors (GPCRs) through its proprietary GEODe™ platform aims to advance therapeutic proteins and antibodies that could transform treatment options for diseases with poor or nonexistent therapies.
The full results of the Phase 1a trial are to be presented at the American Heart Association (AHA) Scientific Sessions in November 2024. This announcement is based on a press release statement from Tectonic Therapeutic.
In other recent news, Tectonic Therapeutics Inc. has been the subject of several significant developments.

The firm's confidence in the drug's market potential and its ability to address an unmet medical need is reflected in their set price target of $55.00.
Further, Tectonic Therapeutics disclosed the departure of its Chief Operating Officer, Dr. Christian Cortis, who will continue to provide consulting services to the company until March 31, 2025. This arrangement suggests a desire for continuity and the retention of his expertise during the transition period.

The firm's positive outlook is influenced by TX45's superior potency and durability, particularly for treating Group 2 pulmonary hypertension.
