Can a daily pill ease a stiff heart condition?
NCT ID NCT07021976
First seen Aug 24, 2026 · Last updated Aug 25, 2026 · Updated 1 time
Summary
This trial tests whether an experimental drug called HRS-1893 can improve symptoms and reduce heart-related events in people with obstructive hypertrophic cardiomyopathy, a condition where the heart muscle thickens and blocks blood flow. About 228 adults aged 18 to 85 with moderate symptoms will receive either HRS-1893 or a placebo. Researchers will measure how many people respond to treatment and track any side effects or major heart problems.

- Active substance
- HRS-1893 tablets
- What this could lead to
- If successful, HRS-1893 could offer a new daily pill to ease symptoms and lower the risk of serious heart complications in people with obstructive hypertrophic cardiomyopathy.
- What could go wrong
- This is a phase III trial, but results are not yet known. The drug may not outperform placebo, and side effects are possible. Success in this trial does not guarantee regulatory approval or widespread availability.

Inclusion Criteria: 1. Age 18-85 years old, gender unlimited. 2. BMI\<35 kg/m2. 3. The diagnosis was obstructive hypertrophic cardiomyopathy. 4. Laboratory determination of echocardiography showed that Rest LVOT-G≥50 mmHg, or Rest LVOT-G≥30 mmHg and LVOT-G≥50 mmHg after Valsalva action. 5. Echocardiographic laboratory tests showed LVEF≥60%. 6. NYHA classification: Grade II - III. 7. Understand the study procedure and sign the informed consent in person, willing to strictly follow the clinical study protocol to complete the study. Exclusion Criteria: 1. Known or suspected invasive, genetic or storage diseases (e.g. Noonan syndrome, Fabre's disease, amyloidosis) that cause cardiac hypertrophy (similar to oHCM). 2. Had a history of severe valvular heart disease. 3. Abnormal laboratory test results during screening, or any other clinically significant abnormal screening laboratory values, which are determined by the researcher to be unsuitable for inclusion. 4. Other circumstances where the researchers consider the subjects unsuitable to participate in this trial, such as physical or mental illnesses or conditions that may increase the risk of the trial, affect the subjects' compliance with the protocol, or affect the subjects' completion of the trial.
