Company Profile


We are Rakuten Aspyrian Inc., a privately funded, clinical stage, Biotechnology Company headquartered in San Diego, California. We are focused on advancing innovative science into breakthrough products that provide cancer patients with new treatments to conquer their disease.

We are supported by investors that have the commitment to build a long-term company that integrates research, development and commercialization of cutting edge cancer therapies with the aim to transform cancer treatments. Our mission is “CONQUERING Cancer. For LIFE.”

We are developing therapies based on a novel proprietary technology platform that utilizes antibodies conjugated with payloads that are specifically activated at the tumor site. Our first clinical product will advance into Phase 3 pivotal clinical testing to treat terminal cancer patients. This is a first-in-class product with unique pharmacological activity and with the potential to have a broad impact in cancer. Given the rapid progression of the clinical studies we are quickly expanding the team to support late stage pivotal clinical development and future commercialization of our products.
