    Therapeutic opportunities for porcupine inhibition in gastrointestinal cancer (ESMO 2023)
    Preclinically, GI tumors with upstream Wnt pathway variants (RNF43 loss of function (LoF), RSPO gain of function (GoF)) are Wnt ligand dependent and exquisitely sensitive to RXC004, a small molecule Porcupine inhibitor...Conclusions Upstream Wnt pathway variants are enriched in GI cancer, in particular Small Bowel cancer, a rare subtype of high unmet need. In MSS CRC cancer, the poor prognosis and high BRAF_V600E co-occurrence with upstream Wnt pathway variants suggests benefit of co-targeting Wnt and MAPK pathways in this population.

    The Wnt Pathway Inhibitor RXC004 Blocks Tumor Growth and Reverses Immune Evasion in Wnt Ligand-dependent Cancer Models. (PubMed, Cancer Res Commun)
    RXC004 has demonstrated the potential to block both tumor growth and tumor immune evasion in a genetically defined, clinically actionable subpopulation of Wnt ligand-dependent gastrointestinal cancers. The clinical utility of RXC004, and other Porcupine inhibitors, in such Wnt ligand-dependent cancers is currently being assessed in patient trials.

    Pre-clinical activity of the Wnt/Beta-catenin pathway inhibitor RXC004 in models of biliary tract cancer (AACR 2023)
    Background: RXC004 is a potent and selective inhibitor of the Wnt pathway regulator Porcupine, and is currently being investigated in phase 2 studies in patients with advanced cancers, including Biliary Tract Cancers (BTCs) +/- Pembrolizumab (NCT04907851 and NCT04907539). These data demonstrate that (1) RXC004 is efficacious in pre-clinical PDX models of BTC, (2) RXC004 induces multiple PD effects in BTC models at the level of gene expression, cell proliferation and cell differentiation, and (3) PDX models of BTC can be clustered based on baseline transcriptomic profiles of Wnt signalling genes and predict RXC004 sensitivity.

    A multi-arm, phase 2, open-label study to assess the efficacy of RXC004 as monotherapy and in combination with nivolumab in patients with ring finger protein 43 (RNF43) or R-spondin (RSPO) aberrated, metastatic, microsatellite stable colorectal cancer following standard treatments. (ASCO 2022)
    As Wnt inhibition can affect bone metabolism, patients undergo a screening DEXA scan and receive prophylactic denosumab throughout the treatment period. For Arm B, a TV of 30% ORR is considered clinically significant against a LRV of 10% ORR (Eng, 2019). RXC004 is also being investigated in a second Phase 2 trial, PORCUPINE 2 (NCT04907851), in Biliary Tract Cancers and RNF-43 mutated Pancreatic Cancers.

    Pre-clinical efficacy of the Wnt pathway inhibitor RXC004 in combination with anti-cancer therapies (AACR 2022)
    RXC004, dosed at 5mg/kg QD (5 days on / 2 days off), was evaluated in combination with either the clinically relevant colorectal triplet chemotherapy regimen (5-fluorouracil 5-FU (25mg/kg), irinotecan (50mg/kg) and oxaliplatin (5mg/kg)) or doublet chemotherapy regimen (5-FU (25mg/kg), irinotecan (50mg/kg)). These data demonstrate that RXC004 in combination with clinically relevant standard of care chemotherapy regimens can lead to potential benefit over chemotherapy alone. The RXC004 induced downregulation of DNA repair pathway genes observed in vitro could contribute to the beneficial effect seen in combination with a PARP inhibitor in vitro as well as the combination effect observed in vivo with standard of care chemotherapy agents.

    Precision medicine for pancreatic cancer in the UK national health service: Lessons learned from the Precision-Panc platform (AACR 2022)
    Somatic driver variants in RNF43 were detected in 15 patients (5.8%) (biomarker for PRIMUS-007, a second-line trial of porcupine inhibitor RXC004). Three patients (1.2%) were found to be MSI high and 18 (9.1%) had a TMB ≥ 4mutations/Mb (eligible for PRIMUS-008; Pembrolizumab/ Olaparib for patients with a high TMB)... We present the experience and real-world challenges in longitudinal fashion in delivering precision medicine for PC, with attrition along patient and tissue pathways. The majority of samples were successfully sequenced and embedding research activities into routine clinical practice is enabling drug and biomarker development.PS. Discrepancy of numbers is due to a real time snap shot of the pipeline.
