RIN Institute (Tokyo, Japan, President: Kentaro Yoshimatsu), a clinical-stage biotechnology company focusing on the treatment of colorectal cancer (CRC) based on monoclonal antibodies (mAb), enters Phase I Clinical Trial for its mAb, ‘RN-1101’. This clinical trial was initiated as the first-in-human study to administer RN-1101 at the National Cancer Center Japan (NCC) Hospital (Chiba, Japan) where RIN Institute originated. A second facility at the NCC is anticipated to join the trial in the near future.

RN-1101 is an mAb whose antigen is a membrane protein molecule, Transmembrane protein 180 (TMEM180) which is highly expressed on colon cancer cells.  The study consists of two phases; a dose escalating study where safety and pharmacokinetics are assessed with solid tumor patients and a cohort expansion study where safety and efficacy are assessed with CRC patients. The clinical trial is funded by national grant, CiCLE.

As a therapeutic antibody, RN-1101’s mechanism of action is cancer cell killing through ADCC activity. It has promoted therapeutic effects regardless of the presence or absence of mutations in the KRAS gene..

CRC is a recognized as a leading cause of cancer-related death, emphasizing the need to identify novel target antigens for mAb development.  FTI continues to support RIN Institute as an existing shareholder and its R&D and fundamental data of RN-1101 and TMEM180 for the development of therapeutics for CRC.
