Chronix at the ASCO 2017 Annual Meeting

Chronix Biomedical

This is the third year that Chronix is presenting its study results at ASCO — this year’s results are from a blinded prospective study validating the use of a CNI Monitor blood test to predict the treatment outcome of patients undergoing immunotherapy.

Predicting Treatment Outcomes in Immunotherapy

Weiss, G. et al. Tumor Cell-Free DNA Copy Number Instability Predicts Therapeutic Response to Immunotherapy.

Genomic analysis of tissue malignancies is well recapitulated by tumor cell free DNA (cfDNA) using the power of Next Generation Sequencing (NGS).

Cohort Study in LiverTx

Schütz E. et al. Graft-Derived Cell-Free DNA – a Noninvasive Early Rejection and Graft Damage Marker in Liver Transplantation PlosMed (2017;) doi:10.1371/journal.pmed.1002286

Graft-derived cell-free DNA (GcfDNA), which is released into the blood stream by necrotic and apoptotic cells, is a promising noninvasive organ integrity biomarker.

HPV Genotyping and Treatment Outcome Predictions

Urnovitz, HB et al. Detection of novel HPV mutations and chromosomal number imbalance (CNI) in laryngeal cancer using next-generation sequencing (NGS). J ClinOncol 32:5s, 2014 (suppl; abstr 6072).

The detection of novel HPV mutations and CNI analysis in a single NGS run on HPV-related diseases provides important information into viral-host dynamics while generating biomarkers that can be correlated with treatment outcomes.

Breast Cancer Liquid Biopsy Screening Test

Beck, J. et al. Cell-free DNA copy number variations as a marker for breast cancer in a large study cohort. J ClinOncol 31, 2013 (suppl; abstr 11013).

Using comparative massive parallel sequencing of cfDNA from cancer patients vs. controls, we were able to show that a 16-region model based on CNV, is useful to distinguish patients with breast cancer from matched controls.

Animal Model for MRD in Breast Cancer

Beck, J. et al. Structural variation in mammary carcinomas and their detection in cell-free plasma DNA. PLOS One 2013 (10.1371/journal.pone.0075485).

Mammary tumors are the most frequent cancers in female dogs exhibiting a variety of histopathological differences. There is lack of knowledge about the genomes of these common dog tumors. Five tumors of three different histological subtypes were evaluated.

Digital PCR of cfDNA for Transplant Rejetion

Beck J. et alDigital droplet PCR for rapid quantification of donor DNA in the circulation of transplant recipients as a potential universal biomarker of graft injury. Clin Chem. 2013 ;59:1732-41

Cell-free DNA (cfDNA) from grafts in the circulation of transplant recipients is a potential biomarker of rejection. Its usefulness was investigated after heart transplantation during the maintenance phase by use of microarrays and massive parallel sequencing of donor and recipient DNA.

NGS of prostate cancer

Schütz, E. et al. Comparative analysis of the chromosomal origins of circulating nucleic acids in breast and prostate cancer. J ClinOncol 28:15s, 2010 (suppl; abstr 10505).

The aim of this study was to find signature CNA sequences from patients with breast cancer (BCa) or prostate cancer (PCa) compared to healthy controls, with respect to their predictive potential, as well as to provide new insights into tumor biology.

Breast Cancer cfDNA with NGS

Beck J, Urnovitz HB, Mitchell WM, Schütz E. Next generation sequencing of serum circulating nucleic acids from patients with invasive ductal breast cancer reveals differences to healthy and nonmalignant controls. Mol Cancer Res 2010; 8:335-42.

Chronix has first used the NGS technology for investigation into the use in breast cancer with very promising results.

NGS of cell-free DNA in animals

Gordon, Paul MK, et al. Disease-specific motifs can be identified in circulating nucleic acids from live elk and cattle infected with transmissible spongiform encephalopathies. Nucleic Acids Research 37.2 (2009): 550-556.

In a 25-month time-course experiment, CNAs were isolated from blood samples of 24 elk (Cervuselaphus) orally challenged with chronic wasting disease (CWD) infectious material.Our results may become useful for the early diagnosis of TSE in live elk and cattle.
