Chronic heart failure affects 6-10% of the general population in the western world. Increasing SERCA2 activity is considered a potential therapy for heart failure. Scientists at Oslo University Hospital have discovered a peptide allowing direct activation of SERCA2 and more selective therapy for heart failure, without most side effects from currently available therapies. Inven2 is seeking collaboration and/or to license the technology to an industrial partner.
SERCA2 controls cardiac contractility by regulating Ca2+ homeostasis in cardiac cells. SERCA2-activity is blocked by PDE3A-SERCA2 protein-protein interaction. No small molecule drugs are yet available to disrupt this pathogenic macromolecular interaction, but we have discovered a peptide selective blocking this. Efficacy in cardiomyocytes has been demonstrated. Development plans: Peptide optimizing and Proof of Principle in rodents.
