Who we are

Pioneering next-generation precision therapies for inherited inherited channelopathies, cardiometabolic diseases and cardiomyopathies

  • A clinical-stage biotechnology company advancing a portfolio of potent, selective inhibitors of serum and glucocorticoid-regulated kinase 1 (SGK1) as precision medicines for inherited channelopathies, cardiometabolic diseases and cardiomyopathies.

  • Human genetic and patient-level data validate SGK1 as a core target for addressing residual risk across cardiovascular diseases.

  • Thryv’s lead candidate, THRV-1268, is being studied in Wave II, a Phase 2/3 study enrolling people with Long QT Syndrome Type 2 and Type 3. ASPIRE-HF, a Phase 2a study in heart failure with reduced ejection fraction (HFrEF), is enrolling soon.

Why SGK1

Genetically-validated cardiometabolic disease node

Despite guideline-directed medical therapy, patients living with Long QT Syndrome, heart failure and other conditions remain at high risk of hospitalization, potentially lethal arrhythmias, and mortality. SGK1 drives pathological electrical and structural remodeling that can cause continued disease progression and poor outcomes.

Electrical instability

Delayed repolarization and QTc prolongation on the ECG, increasing the risk of potentially lethal ventricular arrhythmias.

Inflammation & fibrosis

SGK1 activation triggers an inflammatory and fibrosis cascade in the heart.

Adverse structural remodeling

Continued dysfunction in contractility, relaxation, and structural remodeling

SGK1 inhibition targets these core disease pathways.

Human genetic validation

  • Lower ventricular SGK1 expression is associated with reduced heart failure risk.

  • In the UK Biobank, a rare SGK1 variant was significantly associated with heart failure.

These human genetic findings validate SGK1 as a core disease node to target persistent electrical, functional, and structural disease abnormalities in heart failure and cardiomyopathies.
