Predictive power is one of the most challenging performance metrics in in vitro diagnostics that takes false signals into full account. A high level of predictive power is seen as essential for successful global deployment of any high-volume cancer screening test, both economically and from a regulatory approval standpoint. OTraces is the only company that currently excels by this standard, and has significant patent filings in place.
Ability to use the tumor microenvironment (TME) for cancer diagnosis as we have experienced in our breast and prostate cancer validation trials to date may be our largest accomplishment. The value of this capability is only now starting to gain recognition.
The advantages of using the TME as compared with DNA-based liquid biopsy include determination of whether cancer is present or not; differentiation between aggressive and quiescent tumors; and accurate determination of cancer stage as well as rate of tumor progression.

One of the top priorities in cancer research is for a simple blood test for accurate detection. Even today’s most advanced proteomic and DNA-based tests have predictive power of no more than 80-85% — not regarded a high enough for the rigors of global deployment. Despite progress in liquid biopsy and genetic profiling, these methods are not meant for or being used for detection.


  • OTraces believes that proteomic complexity imposes restrictions on test accuracy that conventional chemistry-based tests cannot resolve.
  • OTraces is the first company to use math- and physics-based measurement science and noise-suppression techniques commonly used in other fields like space communications, and adapted them to the unique challenges of disease detection with remarkable results.
  • In recent tests including validation trials now underway for the company’s blood tests for breast and prostate cancer, OTraces has consistently achieved 95%-plus predictive power.


Convergence of Mathematics and Biology

OTraces was founded in 2008 by CEO Keith Lingenfelter, a leading expert in in vitro diagnostics with extensive Abbott Laboratories and IGEN International, Inc. experience. OTraces was founded to capitalize on emerging trends in proteomics based disease detection technology and on market opportunities including the following:

  • to improve the accuracy of disease detection testing by applying OTraces’ unique math- and physics-based computational techniques.
  • to provide a long-overdue breakthrough in blood-based cancer screening tests, wherein the only significant approved product has been the Prostate Specific Antigen (PSA) assay which was cleared by the U.S. FDA in 1986.
  • to address global market of healthy adults presently not being tested for cancer as part of their routine annual physical exams for lack of an affordable and accurate screening test, — a market substantially larger than the current cancer therapeutics field.


Keith Lingenfelter

Founder, Chief Executive Officer and Member of the Board of Directors

  • Former VP and General Manager, Diagnostics for IGEN International where he managed the development of a breakthrough luminescent immunoassay technology for measuring the concentration of proteins and DNA in biological fluids.
  • Licensed to Boehringer Mannheim (now Roche Diagnostics), Eisai Inc., Akzo Pharmaceuticals (Organon Technika) and ABI/Perkin Elmer. These marketing and development partnerships positioned IGEN for an IPO and eventual sale to Roche for $1.5 billion.
  • Prior to IGEN, Mr. Lingenfelter held a number of management positions at Abbott Laboratories where he was primarily involved in strategic marketing and management of large R&D programs that developed chemistry instrumentation and reagents for clinical assays for the in-vitro diagnostic market.
  • Mr. Lingenfelter has a Master’s degree in engineering from California State University.

Alain Cappeluti

Founder, Founder, Chief Financial Officer and Chairman of the Board of Directors

  • More than 30 years experience in finance and public accounting for private and public companies, and has participated directly in approximately $4 billion of corporate financing transactions.
  • Management experience in the biotech industry includes BioReliance, Human Genome Sciences (HGS), and CoGenesys. He joined HGS in 1992 at its founding and served for many years as VP of Finance. He was part of the team that spun Cogenesys out from HGS in 2006 and was its’ CFO until it was sold to Teva Pharmaceuticals in 2008.
  • Mr. Cappeluti serves on the OTraces Board of Directors and is currently the company’s largest shareholder. It is the Company’s intention to recruit a full-time CFO in the future as warranted by business activity.
