Since 2013, Rakuten Aspyrian has been developing new anticancer therapies based on the Photoimmunotherapy platform.

Rakuten Aspyrian is currently sponsoring a global Phase 3 multicenter clinical study for ASP-1929 to evaluate the efficacy and safety of ASP-1929 in patients with recurrent Head and Neck Cancer and additional Phase 2 studies to evaluate the safety and efficacy of ASP-1929 in patients with other cancer types.

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.
