Astellas Announces Zolbetuximab Meets Primary Endpoint in Phase 3 limelight Trial as First- Line Treatment in Claudin18.2 Positive, HER2-Negative Locally Advanced or Metastatic Gastric and Gastroesophageal Junction( GEJ) Cancers
Astellas PharmaInc.( TSE 4503, President and CEO Kenji Yasukawa,Ph.D., “ Astellas ”) moment blazoned positive topline results from the Phase 3 limelight clinical trial assessing the efficacity and safety of zolbetuximab in combination with mFOLFOX6( a combination authority that includes oxaliplatin, leucovorin and fluorouracil). Zolbetuximab is an investigational first- in- class monoclonal antibody targeting Claudin18.2( CLDN18.2), for the first- line treatment of cases withCLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction( GEJ) adenocarcinoma.
The limelight trial enrolled 566 cases withCLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or GEJ adenocarcinoma. The study met its primary endpoint showing statistical significance in progression-free survival( PFS) for cases treated with zolbetuximab plus mFOLFOX6 compared to placebo plus mFOLFOX6. In addition, the study met a secondary endpoint, overall survival( zilches), showing statistical significance for cases treated with zolbetuximab plus mFOLFOX6 compared to placebo plus mFOLFOX6. The most frequent treatment- imperative adverse events( TEAEs) in cases treated with zolbetuximab plus mFOLFOX6 were nausea, puking, and dropped appetite. Detailed results will be presented at a unborn scientific congress and submitted for publication.
“ I’m agitated by the eventuality for a new treatment option to help cases with advanced- stage gastric cancer or GEJ cancer, ” said Kohei Shitara, MD, Primary Investigator for the limelight trial and Chief, Department of Gastrointestinal Oncology, the National Cancer Center Hospital East in Kashiwa, Japan. “ Gastric and GEJ cancers still have veritably limited treatment options available for cases with an advanced opinion. ”
“ We are pleased and agitated about the positive topline results from the limelight trial of zolbetuximab in combination with mFOLFOX6, and we’ve increased confidence in advancing development of zolbetuximab for the first- line treatment of cases with locally advanced or metastatic gastric cancer, ” said Ahsan Arozullah,M.D.,M.P.H., Senior Vice President and Head of Development Therapeutic Areas, Astellas. “ These topline results farther support the part of CLDN18.2 as an arising biomarker in gastric and GEJ cancer. We look forward to presenting the full results at a scientific congress in the near future. ”
Zolbetuximab acts by binding to CLDN18.2 on the cancer cell face of gastric epithelial cells. Inpre-clinical studies, this list commerce also induces cancer cell death by cranking two distinct vulnerable system pathways — antibody-dependent cellular toxin and complement-dependent cytotoxicity.1 CLDN18.2 is a type of transmembrane protein set up in normal gastric cells and is a major element of epithelial and endothelial tight junctions controlling the inflow of motes between cells.2Pre-clinical studies have shown that CLDN18.2, which can also be present in gastric excrescences, may come more exposed and accessible to targeted curatives with antibodies as gastric excrescences develop.3,,5 Grounded on this study, roughly 38 of screened cases haveCLDN18.2-positive excrescences, defined as CLDN18.2 expression in ≥ 75 of excrescence cells with strong- to-moderate staining intensity grounded on a validated immunohistochemistry assay.6
The Phase 3 limelight trial is a global,multi-center, double-eyeless, randomized study assessing the efficacity and safety of zolbetuximab plus mFOLFOX6 compared to placebo plus mFOLFOX6. Specifically, this study and the Phase 3 gleam trial, which is assessing the efficacity and safety of zolbetuximab plus capecitabine and oxaliplatin( CAPOX) compared to placebo plus CAPOX, are being conducted to give foundational data for nonsupervisory cessions in theU.S., Europe, Asia and other countries encyclopedically.
