TAIPEI, Taiwan, June 21, 2022 /PRNewswire/ -- Rakuten Medical Taiwan, Inc. today announced that their ASP-1929 Photoimmunotherapy Phase 2 clinical trial (ClinicalTrials.gov Identifier: NCT05265013) has enrolled and treated its first patient. This trial is using ASP-1929 photoimmunotherapy based on the Alluminox™ platform in combination with anti-PD1 therapy in head and neck squamous cell carcinoma to measure patient's Objective Response Rate (ORR). The trial will be conducted in 3 medical centers in North Taiwan and 2 medical centers in Central Taiwan.
According to official cancer registration report, head and neck cancer ranks third in male cancer incidence and fourth in male cancer mortality in Taiwan, with an annual incremental of about 10,000 patients. Majority1 of the patients are males between the ages of 40 and 60. Local recurrence or metastasis is one of the leading causes of death in head and neck cancer patients2, and nearly one-half of recurrent or metastatic patients survive for less than one year3. After receiving treatment, about 40% of patients will still face in situ or local recurrence4.
Dr. Chun Wei Huang from Department of Otorhinolaryngology, Head and Neck Surgery of China Medical University Hospital, who participated in the trial, explained: "Currently patients have limited treatment options after recurrence. When surgery, chemotherapy combined with targeted therapy, radiotherapy, etc. fail to show obvious efficacy in treating head and neck cancer, not only the patients but the medical teams are disappointed. Patients are also prone to losing confidence for further treatment. In addition to this phase II clinical trial, Taiwan is also expected to join more clinical trials. The introduction of more clinical trials presents not only new chances for patients, but also new possibilities for head and neck cancer treatment."
"ASP-1929 has been conditionally approved by the MHLW in Japan and we are establishing more clinical evidence to help cancer patients around the world. The investment of this Phase 2 trial reiterates our long-term commitment in developing Taiwan as the foothold to Asia expansion. The enrollment of first patient also demonstrates the robust momentum and tight-knit collaboration of Rakuten Medical around the globe. We look forward to providing patients with impactful new treatment options as soon as possible," said Mickey Mikitani, Co-CEO of Rakuten Medical, Inc.

About Alluminox™ platform
The Alluminox™ 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 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 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 Alluminox 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. Outside of Japan, Alluminox therapies have not yet been approved as safe or effective by any regulatory authority.
Since 2013, Rakuten Medical, Inc. has been using an exclusively licensed antibody complex to develop new cancer therapies based on its Alluminox™ technology platform. Rakuten Medical's first pipeline drug developed using its Alluminox platform is ASP-1929, an antibody-dye 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, cutaneous, esophageal, lung, colon and pancreatic cancers. After binding to cancer cells, ASP-1929 is locally activated by non-thermal red light (690 nm) illumination emitted by a laser device system. Pre-clinical data indicates that Alluminox technology induces a biophysical process that compromises cell membrane integrity, leading to cancer cell death and tumor necrosis. ASP-1929 received conditional early approval from the Japanese Ministry of Health, Labor, and Welfare in September 2020, 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. Outside of Japan, ASP-1929 and the laser device system have not yet been approved by any regulatory authority.
