WATERTOWN, Mass., Oct. 22, 2024 (GLOBE NEWSWIRE) -- Tectonic Therapeutic, Inc. (NASDAQ: TECX) (Tectonic), a clinical stage biotechnology company focused on the discovery and development of therapeutic proteins and antibodies that modulate the activity of G-protein coupled receptors (GPCRs), today announced that it will present a poster at AHA 2024 highlighting Phase 1a data for its lead asset TX000045 (TX45), a long-acting, relaxin. TX45 is being developed as a potential best-in-class therapy for patients with Group 2 Pulmonary Hypertension in Heart Failure with Preserved Ejection Fraction (PH-HFpEF). Tectonic announced topline results from the study on September 19, 2024.

- Presentation ID #: Sa4169
- Presenter: Marcella K. Ruddy, MD, Chief Medical Officer
- Session: A Medley of All Things Pulmonary Hypertension
- Session Date: November 16, 2024
- Session Time: 2:00 PM to 3:00 PM CDT / 3:00 PM to 4:00 PM EDT
About TX45, a long-acting Fc-relaxin fusion protein
Tectonic's lead program, TX45, is an Fc-relaxin fusion protein with optimized pharmacokinetics and biophysical properties that activates the RXFP1 receptor, the GPCR target of the hormone relaxin. Relaxin is an endogenous protein, expressed at low levels in both men and women. In normal human physiology, relaxin is upregulated during pregnancy where it exerts vasodilative effects, reduces systemic and pulmonary vascular resistance and increases cardiac output to accommodate the increased demand for oxygen and nutrients from the developing fetus. Relaxin also exerts anti-fibrotic effects on pelvic ligaments to facilitate delivery of the baby.
Tectonic is evaluating TX45 in an ongoing Phase 1b hemodynamic proof-of-concept study and a Phase 2 clinical proof-of-concept study; both studies are being conducted in patients with PH-HFpEF.
About Group 2 Pulmonary Hypertension in HFpEF
The World Health Organization has defined 5 groups of PH. Tectonic is focused on the Group 2 subtype, a condition that develops due to left-sided heart disease, specifically pulmonary hypertension secondary to left heart failure with preserved ejection fraction (PH-HFpEF).
In patients with PH-HFpEF, chronic heart failure leads to increased blood pressure in the pulmonary arteries, exerting severe strain on the right side of the heart, which adapts poorly to the increased pressure. This increased pulmonary pressure gradually causes worsening exercise capacity, shortness of breath and right-sided heart failure which can lead to death. Although several Group 1 PH (Pulmonary Arterial Hypertension, PAH) medications have been explored in Group 2 PH, to date, no medications have been approved for its treatment.

Forward-looking statements in this press release include, but are not limited to, statements regarding: the design, objectives, initiation, timing, progress and results of current and future preclinical studies and clinical trials of Tectonic's product candidates, including the completed Phase 1a and the ongoing Phase 1b and Phase 2 clinical trials for its lead program, TX45, in PH-HFpEF, including clinical trial design and endpoints. These forward-looking statements are based on Tectonic's expectations and assumptions as of the date of this press release. Each of these forward-looking statements involves risks and uncertainties that could cause Tectonic's clinical development programs, future results or performance to differ materially from those expressed or implied by the forward-looking statements. Many factors may cause differences between current expectations and actual results, including: the potential that success in preclinical testing and earlier clinical trials does not ensure that later clinical trials will generate the same results or otherwise provide adequate data to demonstrate the efficacy and safety of a product candidate; the impacts of macroeconomic conditions, including the conflict in Ukraine and the conflict in the Middle East, heightened inflation and uncertain credit and financial markets, on Tectonic's business, clinical trials and financial position; unexpected safety or efficacy data observed during preclinical studies or clinical trials; clinical trial site activation or enrollment rates that are lower than expected; Tectonic's ability to realize the benefits of its collaborations and license agreements; changes in expected or existing competition; changes in the regulatory environment; the uncertainties and timing of the regulatory approval process; and unexpected litigation or other disputes. Other factors that may cause Tectonic's actual results to differ from those expressed or implied in the forward-looking statements in this press release are identified under the heading Risk Factors in Tectonic's quarterly report on Form 10-Q filed with the U.S. Securities and Exchange Commission (SEC) on August 14, 2024, and in other filings that Tectonic makes and will make with the SEC in the future.
