Chronix Biomedical notes abstract disclosure for forthcoming ASCO presentation  

-     Head and neck cancer study finds CNI score to be a stronger predictor of time to recurrence than current method based on lymph node invasion.

 

San Jose, CA, USA and Göttingen, Germany (18 May 2017) - Chronix Biomedical, Inc., a developer of novel blood-based cancer molecular diagnostics, notes the formal disclosure of the abstract covering its forthcoming presentation of its study in head and neck cancer at the American Society of Clinical Oncology ('ASCO') Annual Meeting on 5 June.

 

The poster presentation is entitled Cell-free DNA for treatment monitoring and outcome predictor in head and neck cancer. It presents data from a study that examined copy number instability (CNI) in circulating tumour DNA from 54 patients undergoing surgery for head and neck cancer and compared the Chronix CNI-based test as a predictor of time to progression with the current method based on the degree of tumour invasion of lymph nodes (pN status).

 

The abstract1 notes that pre-operative CNI scores proved to be a stronger predictor of time to recurrence (p=0.00007) than pN status (p=0.05), with high baseline CNI strongly correlated with time to recurrence (p=0.018). Predicted time to recurrence is an important factor that that can aid the therapeutic decision (i.e. adjuvant treatment) in this condition.

 

Chronix Biomedical's CMO, Prof. Ekkehard Schütz, commented:

"We look forward to presenting our poster at ASCO and sharing the detailed results of this study with our colleagues in the oncology community at this prestigious meeting."

 

Chronix is developing a number of tests for the prognosis and diagnosis of cancer and, in particular, the real-time therapeutic monitoring of response to cancer therapy, based on its proprietary copy number instability score. The company intends to conduct validation studies in individual cancers to support regulatory submissions, the most advanced of which, in pancreatic cancer, is already underway. Similar studies in non-small cell lung, colorectal, breast, ovarian and liver cancers are expected to begin later this year.

 

In the therapeutic monitoring application, Chronix and its collaborators have shown that CNI can accurately determine whether a patient is responding to treatment after just one or two cycles of therapy, potentially 6-8 weeks earlier than is possible using imaging-based methods. Such a test should allow treating physicians to identify the non-responding patients quickly and switch them to alternative treatments sooner, avoiding unnecessary side-effects and potentially achieving better treatment outcomes.

 

The company has previously presented data from studies of its CNI-based tests in patients receiving radiotherapy, chemotherapy2 and immunotherapy3 and recently published the results of a study in patients receiving immunotherapy in the journal, Clinical Cancer Research4.

 

About Chronix Biomedical

Chronix Biomedical, Inc. is a US-based molecular diagnostics company developing blood tests for the screening and monitoring of cancer. Chronix's tests use proprietary algorithms to derive a copy number instability (CNI) score from sequencing of circulating cell-free tumour DNA (cfDNA), which can be used in the prognosis, diagnosis and monitoring of therapeutic response to cancer.
