SAN MATEO, Calif., July 7, 2020 /PRNewswire/ -- Rakuten Medical, Inc. (Rakuten Medical) announced they have entered a multi-year deal with Merck KGaA, Darmstadt, Germany under which Merck KGaA, Darmstadt, Germany will provide cetuximab to Rakuten Medical for its ASP-1929 program. Rakuten Medical uses cetuximab in an intermediate form as the antibody component in its product candidate ASP-1929, an investigational antibody-dye conjugate being studied for the treatment of recurrent, locoregional head and neck cancers. Under this agreement, Rakuten Medical may use cetuximab to produce ASP-1929 for clinical trials and commercial sales.

Earlier this year at the World Economic Forum in Davos, Rakuten Medical and Merck KGaA, Darmstadt, Germany memorialized their intent to join forces to explore ways to help patients conquer cancer. "Rakuten Medical is excited to partner with Merck KGaA, Darmstadt, Germany, a leading science and technology company," said Hiroshi Mikitani, Chairman and CEO of Rakuten Medical. "Rakuten Medical is committed to partnering with world class companies such as Merck KGaA, Darmstadt, Germany in order to carry forward its mission to conquer cancer."

Rakuten Medical's ASP-1929 combines cetuximab and a light activatable dye, IRDye® 700DX. Cetuximab, a monoclonal antibody, targets and binds specifically to the epidermal growth factor receptors (EGFR), which are overexpressed in several cancers. After binding to EGFR-expressing cancer cells, ASP-1929 is locally activated by non-thermal red light (690 nm) illumination emitted by an investigational laser device system. Pre-clinical data indicate that illumination of ASP-1929 induces a biophysical process that compromises cell membrane integrity, leading to cancer cell death and tumor necrosis.

About Rakuten Medical, Inc.

Rakuten Medical, Inc. is a global biotechnology company developing precision, cell-targeting investigational therapies on its Illuminox^TM platform, which, in pre-clinical studies have shown to lead to rapid and selective cell killing and tumor necrosis. Illuminox therapies have not yet been approved as safe or effective by any regulatory authority. Rakuten Medical is committed to its mission to conquer cancer and aims to realize a society where cancer patients can lead fulfilling lives. Headquartered in the United States, Rakuten Medical has 6 locations in 5 countries, including Japan, the Netherlands, Germany and Taiwan. For more information, visit www.rakuten-med.com.

About ASP-1929

Since 2013, Rakuten Medical, Inc. has been using an exclusively licensed antibody complex to develop new cancer therapies based on its Illuminox^TM technology platform. Rakuten Medical's first pipeline drug developed on Illuminox is ASP-1929, an antibody-drug conjugate comprised of the antibody cetuximab and IRDye® 700DX, a light activatable dye. ASP-1929 binds to epidermal growth factor receptors (EGFR), a cancer antigen expressed in multiple types of solid tumors, including head and neck cancer, esophageal cancer, lung cancer, colon cancer, and pancreatic cancer. After binding to cancer cells, ASP-1929 is locally activated by non-thermal red light (690 nm) illumination emitted by an investigational laser device system. Pre-clinical data indicate that Illuminox technology induces a biophysical process that compromises cell membrane integrity, leading to cancer cell death and tumor necrosis. ASP-1929, has achieved Fast Track designation from the FDA and Sakigake Designation from the Japanese Ministry of Health, Labour, and Welfare and is currently under investigation in a global phase 3 clinical trial for recurrent head and neck cancer. Rakuten Medical, Inc. is moving forward with product development by conducting clinical trials of monotherapy and combination therapy with other drugs. ASP-1929 has not yet been approved by any regulatory authority.

About Illuminox™

The Illuminox platform is an investigational platform based on a cancer therapy called photoimmunotherapy, which was developed by Dr. Hisataka Kobayashi and team from the National Cancer Institute in the United States. Rakuten Medical is developing the Illuminox 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 non-thermal 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 Illuminox may also result in local and systemic innate and adaptive immune activation due to immunogenic cell death of the targeted cells and/or the removal of immunosuppressive elements within the microenvironment. Illuminox therapies have not yet been approved as safe or effective by any regulatory authority.
