Redx to Present Zamaporvint Phase 2 Data at ESMO GI

Presentation will include data from both monotherapy and anti-PD-1 combination modules in genetically selected MSS mCRC

Data will also be presented from biliary tract cancer and pancreatic cancer modules

Alderley Park, UK, 20 June 2024 Redx Pharma (JPJ:REDX), the clinical-stage, small molecule biotechnology company, announces that Phase 2 data from zamaporvint (RXC004), a Porcupine inhibitor targeting Wnt-ligand dependent GI cancers, will be presented at the European Society for Medical Oncology Gastrointestinal Cancers Congress (ESMO GI), 26-29^th June, Munich, Germany.

Zamaporvint is a potent, selective, orally-active Porcupine inhibitor in development for hard-to-treat GI cancers. The principal efficacy hypothesis for zamaporvint is for use in combination, which has been investigated in Phase 2 signal searching patient cohorts with anti-PD-1 therapy. Monotherapy for single agent activity has also been investigated. The PORCUPINE study was in genetically-selected patients with microsatellite stable metastatic colorectal cancer (MSS mCRC) as monotherapy and immuno-oncology combination (clinicaltrials.gov NCT04907539 ) . The PORUPINE2 study was in all-comers biliary tract cancer as monotherapy and immuno-oncology combination, and in genetically selected pancreatic cancer as monotherapy ( clinicaltrials.gov NCT04907851).

The data will be presented in two posters, one on the PORCUPINE study and one on the PORCUPINE2 study. Notably, these data demonstrate that zamaporvint, in combination with an anti-PD-1 agent in genetically-selected patient populations has the potential to improve upon efficacy outcomes achieved with standard of care alone. 

Details of the poster presentations are as follows:
