SSTR2 and epi-NET Programme 

This is one of the flagship projects of the newly established UCL/UCLH Cancer Biomarker Centre. The planned work is based on our discoveries in Nasopharyngeal cancer and Olfactory Neuroblastoma

Project Leads

  • Jacklyn Liu (3rd year PhD student): Sinonasal cancers, nasopharyngeal cancer, SCLC, NETs, neuroendocrine prostate cancers, virally induced NETs 
  • Yvonne Power: Pituitary adenoma and brain cancers 

SSTR2 Cancer Programme and epi-NET (companion diagnostic, prognostic biomarker, imaging and therapy)

We recently completed studies assessing the role of the somatostatin receptor 2 (SSTR2) in sinonasal cancers, with a particular focus on nasopharyngeal cancer (n=404 patients) and olfactory neuroblastoma (n=402 patients). With the promising efficacy of SSTR2 as a biomarker and therapeutic target in neuroendocrine tumours, we aim to apply the following to all SSTR2-positive cancers, incl. SCLC, GI tract neuroendocrine tumours, olfactory neuroblastoma, pituitary adenoma, brain cancers, nasopharyngeal cancer and some forms of prostate cancer.

Milestone 1: Optimisation of companion diagnostic biomarker

  • Optimization and automatization of protocol for use as companion diagnostic and prognostic biomarker and automated image analysis (AI scoring algorithm of stained images) – framework for further pipeline development
  • Cancer landscape analysis of SSTR2 with a focus on head and neck cancers and brain tumours and correlation with clinical outcomes (Brain UK ethical approval obtained)

Milestone 2: Identification of the mechanism of SSTR2 overexpression and targetable vulnerabilities

  • Multi-dimensional data analysis 
  • Functional validations in vitro

Milestone 3: In vitro and in vivo testing of SSTR2-targeting agents and targeting related pathways in preparation for Clinical Phase I trials of most promising compounds (in collaboration with industry partner)

Moreover, we are currently investigating the molecular basis of SSTR2 overexpression in these tumours as part of the epi-NET programme.

Collaborators: International networks, incl. EUSICA, INSICA-Brain and industry partners
