Biomarker Trends Are Auspicious for Pathologists and Clinical Laboratories

May 30, 2017 | Digital Pathology, Instruments & Equipment, Laboratory Instruments & Laboratory Equipment, Laboratory Management and Operations, Laboratory News, Laboratory Pathology, Laboratory Testing

Few anatomical tools hold more potential to revolutionize the science of diagnostics than biomarkers, and pathologists and medical laboratories will be first in line to put these powerful tools to use helping patients with chronic diseases

There’s good news for both anatomic pathology laboratories and medical laboratories worldwide. Large numbers of clinically-useful new biomarkers continue to be validated and are in development for use in diagnostic tests and therapeutic drugs.

Clinical laboratories rely on biomarkers for pathology tests and procedures that track and identify infections and disease during the diagnostic process. Thus, trends that highlight the critical role biomarkers play in medical research are particularly relevant to pathology groups and medical laboratories.

Here’s an overview of critical trends in biomarker research and development that promise to improve diagnosis and treatment of chronic disease.

Emerging Use of Predictive Biomarkers in Precision Medicine

Recent advances in whole genome sequencing are aiding the development of highly accurate diagnostics and treatment plans that involve the development and use of Predictive Biomarkers that improve Precision Medicine (PM).

PM involves an approach to healthcare that is fine-tuned to each patient’s unique condition and physiology. As opposed to the conventional one-size-fits-all approach, which looks at the best options for the average person without examining variations in individual patients.

Predictive biomarkers identify individuals who will most likely respond either favorably or unfavorably to a drug or course of treatment. This improves a patient’s chance to receive benefit or avoid harm and goes to the root of Precision Medicine. (Image copyright: Pennside Partners.)

The National Institutes of Health (NIH) defines PM as “an emerging approach for disease treatment and prevention that considers individual variability in genes, environment, and lifestyle for each person.” It gives physicians and researchers the ability to more accurately forecast which prevention tactics and treatments will be optimal for certain patients.

Combining Drugs for Specific Outcomes

Cancer treatment will be complimented by the utilization of combination drugs that include two or more active pharmaceutical ingredients. Many drug trials are currently being performed to determine which combination of drugs will be the most favorable for specific cancers.

Combination drugs should become crucial in the treatment of different cancers treatments, such as immunotherapy, which involves treating disease by inducing, enhancing, or suppressing an immune response.

Biomarkers associated with certain cancers may enable physicians and researchers to determine which combination drugs will work best for each individual patient.

Developing More Effective Diagnostics

In Vitro diagnostics (IVDs) are poised for massive growth in market share. A report by Allied Market Research, states the worldwide IVD market will reach $81.3 billion by 2022. It noted that IVD techniques in which bodily fluids, such as blood, urine, stool, and sputum are tested to detect disease, conditions, and infections include important technologies such as:

Allied Market Research expects growth of the IVD market to result from these factors:

  • Increases in chronic and infectious diseases;
  • An aging population;
  • Growing knowledge of rare diseases; and
  • Increasing use of personalized medicines.

The capability to sequence the human genome is further adding to improvements in diagnostic development. Pharmaceutical companies can generate diagnostic counterparts alongside related drugs.

Biopsies from Fluid Sources

Millions of dollars have been spent on developing liquid biopsies that detect cancer from simple blood draws. The National Cancer Institute Dictionary of Cancer Terms defines a liquid biopsy as “a test done on a sample of blood to look for cancer cells from a tumor that are circulating in the blood or for pieces of DNA from tumor cells that are in the blood.”

At present, liquid biopsies are typically used only in the treatment and monitoring of cancers already diagnosed. Companies such as Grail, a spinoff of Illumina, and Guardant Health are striving to develop ways to make liquid biopsies a crucial part of cancer detection in the early stages, increasing long-term survival rates.

“The holy grail in oncology has been the search for biomarkers that could reliably signal the presence of cancer at an early stage,” said Dr. Richard Klausner, Senior Vice President and Chief Medical Officer at Grail.

Grail hopes to market a pan-cancer screening test that will measure circulating nucleic acids in the blood to detect the presence of cancer in patients who are experiencing no symptoms of the disease.

Clinical Trials and Precision Medicine

The Precision Medicine Initiative (PMI), launched by the federal government in 2015, investigates ways to create tailor-made treatments and prevention strategies for patients based on their distinctive attributes.

Two ongoing studies involved in PMI research are MATCH and TAPUR:

  1. MATCH (Molecular Analysis for Therapy Choice) is a clinical trial run by The National Cancer Institute. The researchers are studying tumors to learn if they possess gene abnormalities that are treatable by known drugs.
  2. TAPUR (Targeted Agent and Profiling Utilization Registry), is a non-randomized clinical trial being conducted by the American Society of Clinical Oncology (ASCO). The researchers are chronicling the safety and efficacy of available cancer drugs currently on the market.

New Tools for Pathologists and Clinical Laboratories

The attention and funds given to these types of projects expand the possibilities of being able to develop targeted therapies and treatments for patients. Such technological advancements could someday enable physicians to view and treat cancer as a product of specific gene mutations and not just a disease.

These trends will be crucial and favorable for clinical laboratories in the future. As tests and treatments become unique to individual patients, pathologists and clinical laboratories will be on the frontlines of providing advanced services to healthcare professionals.

With the promise of obtaining results in just minutes without the need for extensive training, these point-of-care tests and devices create big buzz with each new design.

An yet, after all that progress, most laboratories still depend on their spectrometers, flow cytometers, blood analyzers, and other equipment for the bulk of their testing and routines.

That leaves one major question for clinical laboratory professionals and chip developers alike—when is the revolution? (more…)

Paper Microfluidic Devices Offer New Potential for Affordable Point-of-Care Tests for Use in Developing Countries That Have Few Clinical Laboratories

Jul 29, 2016 | Instruments & Equipment, Laboratory Management and Operations, Laboratory News, Laboratory Operations, Laboratory Pathology, Laboratory Testing

Paper-based devices could perform complex, multistep diagnostic tests at a fraction of the cost of traditional medical laboratory analysis

Many research teams are racing to create paper-based devices for medical laboratory tests. Their primary goal is develop a cheap, fast, reliable way to perform diagnostic testing in third world settings, where modern clinical laboratories are few and far between. One development team is working to combine lab-on-a-chip technologies with the low cost of paper-based platforms.

Meanwhile, over the past decade, point-of-care testing (POCT) has revolutionized diagnosis and treatment options for a myriad of conditions. In developing regions or remote areas, low-cost POCT improves accessibility to vital tests for infectious diseases, such as HIV, Malaria, and Ebola, as well as acute medical conditions, such as sepsis.

In the past eight years, Dark Daily has reported many times on the emergence of new POCT devices. From lactic acid screening to the lab-in-a-needle, which is used for detecting liver toxicity, the ability to produce a quick and accurate diagnosis without intensive clinical laboratory testing is growing.

However, one area where many POCT devices face challenges is in surviving extended environmental exposure. This does not pose an issue in major research hospitals or health systems. However, the consequences can be severe when considering the often harsh, resource-limited conditions of developing countries—one area in which POCT stands to offer the greatest value. (more…)

New Medical Laboratory Test from Washington University School of Medicine Could One Day Replace the Popular PCR Assays Used by Many Pathologists

Feb 5, 2016 | Laboratory Pathology, Laboratory Testing

Called ‘ViroCap,’ this new diagnostic technology is able to discover more viruses in patient samples, as compared to PCR genome sequencing tests

It could be the ultimate multi-analysis medical laboratory test ever. Researchers at Washington University School of Medicine in St. Louis have developed a diagnostic test that they claim tests for any virus infecting people and animals.

The new test, called ViroCap, detects viruses that standard tests based on genome sequencing cannot, according to a university statement.

Viruses Make for a Popular Research Subject

Are virus tests going, well, viral? It was just a few weeks ago that Dark Daily reported on research at Howard Hughes Medical Institute (HHMI) aimed at unlocking virus detection beyond one pathogen at a time. (See Dark Daily, “Researchers at Howard Hughes Medical Institute Develop Blood Test That Reveals a Patient’s Viral History; Could Reduce Unnecessary Clinical Laboratory Testing,” December, 30, 2015.)

The HHMI research resulted in VirScan, an alternative to medical laboratory tests that test for specific viruses one at a time, and which can detect all diseases a patient has had over his or her lifetime, according to an HHMI news statement about the new technology. (more…)
