Developing New Polymer-Based Medicines for Undertreated Conditions

Relypsa is a biopharmaceutical company leading the discovery, development and commercialization of polymer-based medicines to treat conditions that are often overlooked and undertreated, but that can have a serious impact on patient lives or even be life-threatening. We are focused on developing medicines that will change treatment paradigms.

Relypsa was founded in October 2007 and is headquartered in Redwood City, Calif. In September 2016, Relypsa became a Vifor Pharma company. Learn more about Vifor Pharma here.

Today, we have more than 400 employees united by a passion for improving people’s lives. Our unique technology platform includes a proprietary high-throughput chemistry process, enabling us to efficiently explore thousands of potential polymer medicines for each disease we seek to address.

Our polymers are non-absorbed, meaning they act within the gastrointestinal tract and do not get absorbed into the bloodstream or other parts of the body. Our polymer technology may be able to address many health conditions in need of viable treatment options.
