Meet the Developers

D. James Morré, Ph.D. and Dorothy M. Morré, Ph.D. are the developers of the ONCOblot® Test, a Laboratory Developed Test for early cancer detection.

The Morré’s are committed to the premise that understanding cancer is the key to its conquest. Their ONCOblot® test, a new blood test for cancer, is based on more than 20 years of basic research.

Abstract Introduction:
All neoplastic cells express one or more members of a unique family of tumor-associated cell surface ubiquinone (NADH) oxidase proteins with protein disulfide-thiol interchange activity (ENOX2 or tNOX proteins) that are characteristically blocked by quinone site inhibitors with anti-cancer activity.

Accuracy and Sensitivity Data and Information


Read Accuracy Results of 800 ONCOblots

A summary is provided below for convenience.  Please see document for details.

Based on the original database from 01/01/2013, analyses of over 800 ONCOblots® covering 26 different kinds of cancers with clinically confirmed diagnoses:

99.3% were positive for cancer based on ENOX2 presence
Of these, the organ site of the cancer was determined correctly in 96% of the samples
There were less than 1% false negatives

A summary from this Report is provided below for convenience.  Please refer to Report for complete details regarding our best current estimates as of April 29, 2015:

False positives:  0.06%
False negatives:  0.6%
Limit of detection:  200 femtomoles of ENOX2, approximately 2million cancer cells or 0.8-1.2 mm diameter.
Misidentification of tissue of origin:  2.8% – 3.3%

Early Detection Trial Results

Evaluation of subjects enrolled in an early detection trial (Hannau et al. Clinical Proteomics 2014 11:2) revealed the following trends: 

• Of 110 subjects presenting with no clinical symptoms, 66 subjects or 60% were negative in the ONCOblot® test.

• Of the same 110 subjects presenting with no clinical symptoms, 44 subjects or 40% were positive in the ONCOblot® test.

This aligns with current data of 1 in every 3 individuals is expected to contract cancer in their lifetime.

• Of the subjects testing positive for cancer, 9 were identified as non-small cell lung cancer, 7 as breast cancer, 4 as colorectal and 3 each for blood cell, ovarian, prostate and cervical cancer, 2 for squamous cell and 1 each for melanoma, mesothelioma, bladder, thyroid and uterine cancer.  Organ site could not be identified for 5 patients as either being represented by a fully processed ENOX2 (generic) transcript variant or as not being represented in the database at the time of the study.

A large-scale clinical trial to demonstrate the efficacy of ONCOblot® as a cancer screening test has not been completed. Cancer screening is not an approved utility of the ONCOblot® Test. The ONCOblot® test is a confirmatory test that is intended to be used by the ordering physician in conjunction with the patient’s complete medical history and the results of standard of care testing. Cancers progress at varying rates and therefore, the frequency of diagnostic testing is subject to the ordering physician’s clinical judgement.
