Introduction

The seasoned scientists at IOS focus on creating & optimizing sensing at levels of competence not normally seen in industry.

Their unique depth and breadth of scientific expertise has enabled IOS to solve challenging physical, chemical, biological, and optical challenges and convert them to extraordinary products.

The scientists are driven to succeed by their shared passion for knowledge and growth, and the desire to apply that knowledge to remedy real-world problems, from healthcare to environmental sustainability.

MISAA, LLC contains the IP for the TAC Assay and has an operating agreement with IOS to use its scientists, facilities, etc. At MISAA (Monitoring Immunosupressants Anywhere Anytime), our mission is to use our knowledge and experience to improve the health and well-being of the transplant community around the world.

FDA 510(k) presub submitted with feedback from the FDA agreeing with our predicate and clearing a 510(k) path forward. The 501(k) is a FDA regulatory process for medical devices which allows them to be approved based on a demonstration of substantial equivalence to a predicate device that is already legally marketed. In other words, we believe we’ll be able to bring this product to market more quickly than a full FDA premarket approval.

“Reducing time between blood draw to test will allow for dose adjustment in matter of hours as opposed to days. Lead to better patient outcomes.”

Problem

Tacrolimus (TAC) is an essential immunosuppressive drug for solid-organ and tissue transplant patients.

Frequent patient monitoring is critical to its success – TAC has a short therapeutic window that differs widely between individuals – too high a level causes drug toxicity, too low a level causes transplant rejection. Chronic rejection is a problem and a key solution is tighter control of immunosuppressant levels.

Current monitoring is by frequent blood draws measured with liquid chromatography–mass spectrometry (LC-MS/MS). Such testing is painful, complex and costly and limitations on same-day turnaround can compromise effective dose adjustments.

Solution

Over the past three years, IOS has developed and patented (pending) an ELFA for rapid, accurate, reliable and highly sensitive lab and point of care monitoring of tacrolimus levels in capillary blood from a fingerstick.

With over $4MM of non-dilutive funding, IOS has validated its fingerstick assay against the laboratory venus blood draw test.

This enables clinicians to adjust immunosuppressant drug (ISD) levels in the order of minutes rather than days.

It is less invasive and user friendly for patients, leading to improved patient outcomes.

Trong Nguyen, PhD
Principal Investigator for IOS DoD SBIRs and to MISAA
Leads the team developing novel quantitative lateral flow assays for the detection and measurement of biomarkers and drugs in low-volume whole blood and saliva samples. Developed a proprietary optimal buffer formula for each assay and labeling technique based on DNA hybridization that enhances assay sensitivity to sub-nanogram per microliter or low-picogram per milliliter sensitivity levels.

Maria Ortega, MS
Scientist
Assists in the development of rapid biomedical diagnostic assays using immunochemistry and enzymatic technology including optimizing assay conditions and experimental methods to achieve a working biomedical device for the detection and measurement of various biomarkers. Work includes analyzing data and planning experiments for the screening of material, formulating stability solutions for reagents to achieve an appropriate shelf-life, optimizing assay conditions to improve assay sensitivity and achieve measurements in relevant concentration range.

Emily Vuu
Scientist
As a part of the team, optimizes lateral flow assay for detection of biomarkers (tacrolimus, interleukin-6, matrix metalloproteinase-3) in blood and saliva samples. Streamlines luminescent, biochemical fiber optic production for electronic blood pressure sensors.

    Tac-Assay is our patent pending, tacrolimus in...

    Tac-Assay is our patent pending, tacrolimus in vitro diagnostic—a proprietary, simple, low-cost test with the potential to be administered much like a blood glucose test. Tac-Assay takes only 15 minutes instead of 12 hours as needed for the gold-standard LC-MS method, all with essentially the same sensitivity over the therapeutic range.

    This exciting new product also uses a highly portable, fast responding eLFA cassette and only a fingerstick of patient blood instead of several mL.

    As MISAA CEO Reuben Sandler explains, “Tac-Assay will enable monitoring of tacrolimus levels at nearby clinical labs, doctors’ offices and eventually in the home, eliminating the need for lengthy patient visits to a hospital or clinical lab. This could significantly improve the quality of life for transplant patients.”

    By helping us bring the revolutionary Tac-Assay to market, you are returning precious time and resources to transplant patients that need it most.
