Early detection news

During 2022/23, several of the licensable diagnostic technology platforms in the Cancer Research Horizons biomarker and diagnostic portfolio progressed towards becoming products. They represent a combination of new approaches that stem from a greater understanding of cancer cell evolution and tools to interrogate the complexities of cancers cells and the environment that surrounds them. Here is a summary of some of these technology platforms and the recent progress they made. Click the links in the description to find the full details and licensing opportunities.

Platform

ORACLE

Description


The Outcome Risk Associated Clonal Lung Expression (ORACLE) diagnostic approach/genetic test combines machine learning with an understanding of cancer cell evolution to distinguish between high- and low-risk tumours. The test will help to guide early clinical decision making for lung cancer patients.

Business and development status


Patent application filed


Proof of concept: The investigators analysed multi-region, multiomic data from patients with non-small cell lung cancer (NSCLC) recruited within the TRACERx study. to address the diagnostic challenges associated with genomic intra-tumour heterogeneity (ITH) and chromosome instability (CIN). This challenge is a common features across cancer types. This new approach robustly predicted which early-stage lung cancer patients were at a high risk of mortality, including those missed by existing clinical criteria.

ECLIPSE

Description

ECLIPSE is a novel, highly sensitive informatic method developed to track tumour evolution over time using low circulating tumour DNA (ctDNA) fraction samples (>0.1%) of liquid biopsies by leveraging genomic information for each mutation from a matched tumour tissue sample. The approach has the potential to make the detection power for ctDNA much higher than standard liquid biopsy methods.

International patent application filed


Proof of concept: In a cohort of ctDNA-positive samples within the TRACERx study, ECLIPSE detected clonal ctDNA in 61% of patients, while standard liquid biopsy methods detected clonal ctDNA in only 16% of patients.

T Cell ExTRECT

Description

T Cell ExTRECT is an informatic method of DNA sequencing analysis that enables the estimation of T cell fraction present in tumours. Measuring the fraction would potentially provide an efficient method for assessing immune microenvironment influences on tumour evolution that have prognostic and predictive insights into a patient’s response to immunotherapy.

Validation and proof of concept: Using five different tests, the accuracy of the T Cell ExTRECT in comparison to RNA sequencing methods. Additionally, a low T Cell ExTRECT score correlated with a worse prognosis in a cohort of lung adenocarcinoma patients. T Cell ExTRECT was predictive of checkpoint inhibitor therapy response across eight main cancer types.

PCF-SELECT

Description

Designed to detect genomic aberrations informative for therapeutic selection, PCF-SELECT is a circulating tumour DNA (ctDNA)-targeted, next-generation sequencing panel for use before a change of treatment for metastatic castration-resistant prostate cancer (mCRPC). Key benefits of this technology include detection of a breadth of genomic alterations at high sensitivity, a computational approach to minimise false positives, and a need for only low amounts of plasma DNA.

Although currently optimised for prostate cancer, the approach could be applied to other cancer types.

Business and development status


Proof of concept: The verification of PCF-SELECT and its associated computational method’s performance under conditions including the ability to detect lesions at low ctDNA level and within complex copy number states, was repeatedly achieved using synthetic simulations, serial mCRPC patient samples and comparisons with independent standard assays.

AI partnerships

With the rapid growth in the application of artificial intelligence (AI) and machine learning (ML) to drug discovery, Cancer Research Horizons has been partnering with AI-enabled biotechs to help address key questions in drug development. In particular we have been excited by the possibility of using AI to help inform development of some of our late-stage preclinical assets and in particular the insights that AI can provide in disease positioning. Through partnerships with Turbine and Predictive Oncology, we are building hypotheses for our CDC7 and glutaminase inhibitors that will allow us to identify the most suitable patient population and map a potential path to the clinic.
