- Findings in the clinic and preclinical study presented at India's largest medical conference for head and neck cancer<\/i><\/b><\/p>\n

 <\/p>\n

Rakuten Medical, Inc., a global biotechnology company developing and commercializing precision, cell targeting therapies based on its proprietary Alluminox\u2122 platform, is pleased to announce that there were three invited presentations on the Alluminox treatment (photoimmunotherapy) at the 23<\/span>rd<\/sup> National Conference of Foundation for Head and Neck Oncology (FHNO 2023) held in Daman, India, on December 22-24, 2023. These presentations were delivered by two physicians who have extensive clinical experience in Alluminox treatment in Japan and track record of research for further development of this therapy.<\/span><\/p>\n

 <\/p>\n

* Rakuten Medical\u2019s EGFR-targeted therapy based on Alluminox\u2122 platform is investigational outside of Japan and not approved in India for commercial use. All other therapies based on the platform are investigational globally<\/em>.<\/span><\/i><\/p>\n

 <\/p>\n

Three invited presentations on Alluminox treatment at FHNO 2023<\/b><\/span><\/p>\n

Title: <\/span>Photoimmunotherapy for Lower Gingival Cancer<\/b><\/p>\n

Presenter: <\/span>Daisuke Nishikawa, MD, PhD, Department of Head and Neck Surgery, Aichi Cancer Center, Japan<\/b><\/p>\n

Session: INVITED VIDEOS<\/span><\/p>\n

Time & Date: 8:00 \u2013 9:00 am, December 22, 2023 (5 mins for his presentation)<\/span><\/p>\n

This video presentation shared the concepts of patient selection and treatment procedures such as needle puncture and light illumination in the commercial setting in Japan. The treatment for a patient with lower gingival cancer and a history of radiotherapy was shared in the video. Management of the patient\u2019s adverse events such as postoperative edema and the time course of a fistula that occurred with tumor shrinkage were also presented.<\/span><\/p>\n

 <\/p>\n

Title: <\/span>Photoimmunotherapy for Recurrent Head and Neck Cancers \u2013 Japanese experience<\/b><\/p>\n

Presenter: <\/span>Daisuke Nishikawa, MD, PhD, Department of Head and Neck Surgery, Aichi Cancer Center, Japan<\/b><\/p>\n

Session: RECURRENT & METASTATIC DZ<\/span><\/p>\n

Time & Date: 3:00 \u2013 4:30 pm, December 22, 2023 (15 mins for his presentation)<\/span><\/p>\n

This presentation included case reports, clinical outcomes and safety of the Alluminox treatment in the commercial setting in Japan, as well as the results of translational research on immune response. In 26 treatments administered to 15 patients at the Aichi Cancer Center from January 2021 to December 2023, generally good responses were observed. Release of damage-associated molecular patterns (DAMPs) and production of chemokines, which suggest an immune response, were observed in post-treatment peripheral blood samples from 7 treatments given to 5 patients at the Center, potentially suggesting induction of immunogenic cell death with this treatment<\/span>1<\/sup>. In Japan, this treatment is currently positioned as the last line of locoregional treatment for recurrent head and neck cancer, and is being conducted with special consideration for adverse events such as pain, edema, fistula, and photosensitivity.<\/span><\/p>\n

 <\/p>\n

Title: <\/span>Near-infrared Photoimmunotherapy: Translational research and clinical application<\/b><\/p>\n

Presenter: <\/span>Ryuhei Okada, MD, PhD, Department of Head and Neck Surgery, Tokyo Medical and Dental University Hospital<\/b><\/p>\n

Session: DR SUDHIR BAHADUR SCIENCE SYMPOSIUM<\/span><\/p>\n

Time & Date: 8:30 \u2013 9:30 am, December 24, 2023 (15 mins for his presentation)<\/span><\/p>\n

In a case report of a patient with hypopharyngeal carcinoma treated with this EGFR-targeted therapy in the commercial setting in Japan, tumor shrinkage was observed during the course of 4 treatments, and disease control was achieved with this treatment alone for one year prior to progressive disease. Preclinical studies conducted to further improve treatment outcomes were also presented. In a mouse study of tumor cell-targeted photoimmunotherapy (PIT) in combination with anti-PD-1, the combination group showed statistically significant reduction of tumor growth and prolonged survival compared to the control or monotherapy groups.<\/span>2<\/sup> In a preclinical study of PIT targeting CD25, local depletion of Tregs in the tumor microenvironment resulted in rapid activation of effector cells, suggesting immune activation and abscopal effect.<\/span>3<\/sup> In other preclinical studies, PIT targeting CTLA4 showed anti-tumor effects by locally eliminating Tregs in the tumor microenvironment,<\/span>4<\/sup> and PIT targeting both EGFR and CD25 demonstrated statistically significant tumor growth inhibition compared to the control or monotherapy groups<\/span>5<\/sup>.<\/span><\/p>\n

Alluminox treatment Using ASP-1929: Approved in Japan and investigational globally<\/b><\/p>\n

 <\/p>\n

A drug \u201cAkalux\u00ae IV Infusion 250 mg\u201d (development code: ASP-1929) and a device \u201cBioBlade\u00ae Laser System\u201d, both of which were developed based on Rakuten Medical's Alluminox\u2122 platform, received the world-first marketing and to-date only approval in Japan for unresectable locally advanced or recurrent head and neck cancer in September 2020. Since commercial launch in January 2021, more than 400 treatments have been provided in Japan (as of December 2023).\u00a0<\/span><\/p>\n

 <\/p>\n

Alluminox treatment using ASP-1929 is currently being evaluated in a global Phase 3 clinical trial (ASP-1929-301 study \/ ClinicalTrials.gov Identifier: <\/span>NCT03769506<\/span><\/a>, CTRI Number: <\/span>CTRI\/2023\/05\/052728<\/span><\/a>) for locoregional, recurrent head and neck squamous cell carcinoma (HNSCC) in countries and regions including the United States, India and Taiwan. The first patient in India enrolled in ASP-1929-301 study received study treatment in August 2023.\u00a0 For more details, please see our <\/span>press release<\/span><\/a>.<\/span><\/p>\n

 <\/p>\n

Rajesh A Kantharia, M.D., Organizing Chairman of FHNO 2023 and principal investigator of the ASP-1929-301 study at Kailash Cancer Hospital and Research Center, stated \u201cWe are pleased to have both physicians at FHNO 2023 to share their experiences in Japan with this novel therapy with prestigious healthcare professionals working on head and neck cancer across India. Head and neck cancer, which afflicts a large number of the Indian population, is one of the biggest medical challenges in our country. Photoimmunotherapy is being developed as highly selective for targets such as tumor cells, and it is also being studied extensively in both monotherapy and combination therapy, thus I see great potential in this continually evolving investigational technology. In ASP-1929-301 study in India, we have started treating enrolled patients. \u00a0We hope that this investigational therapy will contribute to the improvement of head and neck cancer care in India.\u201d<\/span><\/p>\n

About Alluminox\u2122 platform\u00a0<\/b>\u00a0<\/span><\/p>\n

The Alluminox\u2122 platform is an investigational technology platform based on a cancer therapy called photoimmunotherapy, which was developed by Dr.\u00a0Hisataka Kobayashi\u00a0and team from the National Cancer Institute in\u00a0the 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.\u00a0The device component consists of a light source that locally illuminates the targeted cells with light to transiently activate the drug.\u00a0Pre-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\u00a0Japan, Alluminox therapies have not yet been approved by any regulatory authority.<\/span><\/p>\n
