Our Approach
Developing
breakthrough
products.
We have a robust pipeline of programs to prevent disease progression, improve outcomes and protect against organ damage in cardio, renal and metabolic diseases.
RBT-1 (stannic protoporfin / iron sucrose)
RBT-1 (stannic protoporfin/iron sucrose) is a single dose IV drug that is given over 1-2 hours, 24-48 hours prior to patients undergoing elective cardiac and or valve surgery. RBT-1 has started its Phase 3 US registrational study to reduce the risk of post operative complications and improve outcomes following cardiothoracic surgery. The drug has received FDA Breakthrough and Fast Track Designations.
Veverimer
Veverimer (Alezuris™) is an oral, non-absorbed hydrochloric acid binder that was acquired from Tricida. We are targeting several indications where Veverimer’s mechanism of action as a hydrochloric acid binder within the gastrointestinal tract may provide benefit in treating orphan diseases with an unmet medical need.
