San Diego, California \u2013 Rakuten Medical Inc. announced the commencement of a Phase 1, open-label, dose-escalation, clinical trial (RM-1995-102; <\/span>jRCT number: 2031220721<\/span><\/a><\/u>) in Japan for Alluminox\u2122 treatment (photoimmunotherapy), utilizing our newly developed anti-CD25 antibody-dye conjugate, RM-1995 and a device for laser illumination at a wavelength of 690 nm. The trial focuses on patients with advanced or recurrent solid tumors with liver metastasis.<\/span><\/span><\/p>\n

 <\/p>\n

This is a Phase 1 clinical trial for patients with advanced or recurrent solid tumors with at least one metastatic liver lesion that can be illuminated with a laser and for whom no standard treatment is available. The study will evaluate the safety and tolerability of the treatment with the drug as a monotherapy (Phase 1a and 1b) and in combination with pembrolizumab (Phase 1c) to determine the maximum tolerated dose (MTD) or maximum accepted dose (MAD) and the recommended dose to be used in a Phase 2 clinical trial. The safety of the medical device for liver metastases will also be evaluated.<\/span><\/span><\/p>\n

 <\/p>\n

Primary sites of liver metastasis include tumors of the digestive system, such as colorectal, stomach, and pancreatic cancers, as well as breast and lung cancers. The liver is a frequent metastatic organ in various cancers<\/span>1<\/span><\/sup>, and these metastatic lesions are associated with a poor prognosis<\/span>2<\/span><\/sup>.<\/span><\/span><\/p>\n

 <\/p>\n

Hiroshi Mikitani, Co-CEO of Rakuten Medical, said:<\/b><\/span> \u201cWe are delighted to have commenced the clinical trial of Alluminox\u2122 treatment using our second newly developed compound, RM-1995, in Japan. Liver metastasis is a common occurrence in various cancers, and with the limited efficacy of current treatments. We hold firm in our belief that this treatment has the potential to be a beacon of hope for patients awaiting novel therapies. It has been ten years since my father's pancreatic cancer became the catalyst for my involvement in developing Rakuten Medical\u2019s Alluminox technology. I sense we have taken a significant step towards the development of a treatment for a wide range of cancers, including pancreatic cancer.<\/span><\/span><\/p>\n

In November 2021, the development of this study, \"Development of innovative cancer therapy targeting regulatory T cells using anti-CD25 antibody-dye complex (RM-1995),\" was selected by the Japan Agency for Medical Research and Development (AMED)<\/span><\/a><\/u>. This study is conducted with the support of AMED.<\/span><\/span><\/p>\n

 <\/p>\n

About RM-1995<\/b><\/span><\/span><\/p>\n

RM-1995, developed by Rakuten Medical using its Alluminox\u2122 platform, is an antibody-dye conjugate comprised of a monoclonal antibody specific for cell-surface interleukin 2 (IL-2) receptor <\/span>\u03b1<\/span>-chain (CD25) and IRDye\u00ae 700DX (IR700), a light-activatable dye. RM-1995 photoimmunotherapy is designed to specifically kill CD25+ regulatory T cells (Tregs) within solid tumors once illuminated with 690nm, intended to deliver nonthermal red light<\/span>3<\/span><\/sup>. Rakuten Medical\u2019s preclinical data has suggested that RM-1995 photoimmunotherapy treatment can be utilized to specifically deplete intratumoral Tregs, thereby alleviating local Treg-mediated restraint within the tumor microenvironment, rapidly improving the CD8 T cell: Treg ratio, and reinvigorating effector CD8+ T cell responses.<\/span><\/span><\/p>\n

 <\/p>\n

About Alluminox\u2122 platform\u00a0<\/b><\/span>\u00a0<\/span><\/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 Japan, Alluminox therapies have not yet been approved by any regulatory authority.<\/span><\/span><\/p>\n
