Alluminox therapies have not yet been approved outside of Japan. Rakuten Medical is committed to its mission to conquer cancer by delivering our innovative treatments as quickly as possible to as many patients as possible all over the world . The company has offices in 6 countries, including the United States, where it is headquartered, Japan, the Netherlands, Taiwan, Switzerland and India.

Rakuten Medical is developing the Alluminox platform as a technology consisting of a drug, device, and other related components. The drug component of the platform consists of a targeting moiety conjugated with one or more dyes leading to selective cell surface binding. The device component consists of a light source that locally illuminates the targeted cells with light to transiently activate the drug. Pre-clinical data have shown that this activation elicits rapid and selective necrosis of targeted cells through a biophysical process that compromises the membrane integrity of the targeted cells. Therapies developed on the Alluminox platform may also result in local and systemic innate and adaptive immune activation due to immunogenic cell death of the targeted cancer cells and\/or the removal of targeted immunosuppressive cells within the tumor microenvironment. Outside of Japan, Alluminox therapies have not yet been approved by any regulatory authority.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>About ASP-1929<\/strong><\/p>\n<p>Rakuten Medical\u2019s first pipeline drug developed on its Alluminox\u2122 platform is ASP-1929, an antibody-dye conjugate comprised of the antibody cetuximab and IRDye\u00ae 700DX, a light activatable dye. ASP-1929 binds to epidermal growth factor receptor (EGFR), a cancer antigen expressed in multiple types of solid tumors, including head and neck, breast, lung, colorectal, prostate and pancreatic cancers. After binding to cancer cells, ASP-1929 is locally activated by illumination with red light (690 nm), emitted by a laser device system to produce a photochemical reaction. This reaction is believed to cause damage to the membrane of cancer cells, leading to selective necrosis of cancer cells. ASP-1929 received Fast Track designation from the U.S. Food and Drug Administration (FDA) in January 2018, and is currently under investigation in a global Phase 3 clinical trial for recurrent head and neck cancer. In Japan, ASP-1929 received marketing approval from the Japanese Ministry of Health, Labor, and Welfare for unresectable locally advanced or recurrent head and neck cancer in September 2020, under the Sakigake Designation System and the Conditional Early Approval System. Outside of Japan, ASP-1929 has not yet been approved by any regulatory authority.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Forward Looking Statements\u00a0<\/strong><\/p>\n<p>This press release contains forward looking statements that correspond to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.
