The software applications (apps) and hardware monitoring devices involved in digital therapeutics enable physicians and patients to target and alter specific behaviors that affect certain medical conditions, such as substance abuse or depression. Combined with or without drugs, digital therapeutics are achieving positive results, according to the United Kingdom’s PwC (PricewaterhouseCoopers) Health Research Institute (PwC HRI).
The report goes on to state that digital therapeutics “is
reshaping the landscape for new medicines, product reimbursement and regulatory
oversight … [and that] new data sharing processes and payment models will be
established to integrate these products into the broader treatment arsenal and
regulatory structure for drug and device approvals.
“Connected health services,” the report continues, “enabled by devices that transmit data or connect to the Internet, give additional visibility into care delivery and new ways to improve patient outcomes.”
Digital therapeutics combine apps and monitoring devices for
the management and treatment of medical conditions. While similar to customer
wellness apps, digital therapeutics focus on specific clinical outcomes.
The non-profit Digital Therapeutics Alliance says that, unlike common “wellness” apps, digital therapeutics “possess the unique ability to incorporate additional functionalities into a comprehensive portfolio of synchronous products and services. This includes potential integration with mobile health platforms; the provision of complementary diagnostic or adherence interventions; the ability to pair with devices, sensors, or wearables; the delivery of interventions remotely; and integration into electronic prescribing, dispensing, and medical record platforms.”
“Digital therapeutics are the next frontier,” Sai Jasti, Chief Data and Analytics Officer, GlaxoSmithKline (NYSE:GSK), told PwC HRI. “I think we will see a lot more collaboration between pharmaceutical and technology companies to drive this forward, ultimately to the benefit of patients.”
Digital Therapeutics That Already Have FDA Approval
Digital therapeutics and their connected devices are subject
to the approval process of the federal Food and Drug Administration (FDA), and
some have already received that coveted clearance:
reSET from Pear Therapeutics is a 90-day prescription digital therapeutic (PDT) for substance use disorder (SUD). The Boston-based company also worked with Sandoz Inc., a division of Novartis, to receive FDA approval for reSET-O, a PDT for treating individuals with Opioid Use Disorder (OUD).
“Digital technologies and data science have incredible potential to unlock the next chapter of medical innovation and to help individuals finally take control of their own health in a meaningful way,” said Richard Francis, Division Head and CEO, Sandoz, in a press release. “New digital therapeutics such as reSET-O also have the potential to fundamentally change how patients interact with their therapies and thus improve patient outcomes.”
Both reSET and reSET-O are software mobile apps that use cognitive behavioral therapy (CBT) to help individuals struggling with addictions.
“Nearly 50,000 drug overdose deaths involving opioids, including prescription pain medications and heroin, took place in the U.S. in 2017,” said Corey McCann, MD, PhD, President and CEO of Pear Therapeutics, in the press release following receiving FDA approval. “There is an urgent need for new and innovative therapeutics to address this public health epidemic. This groundbreaking decision by the FDA ushers in a new standard for treating patients with Opioid Use Disorder and it signals a new path for therapeutic software to be used in conjunction with pharmacotherapy to improve efficacy.”
Natural
Cycles is a birth control app created by a Sweden-based company of the same
name. It was approved by the FDA in 2018. This mobile app helps women track
their fertility to prevent unwanted pregnancies via the rhythm method. The app
analyzes data from past menstrual cycles and body temperature readings to
determine when the user is most fertile. On the days the user is most likely to
be ovulating, the app displays “Use Protection” on the mobile device’s screen.
“We know that women are more likely to use contraceptive methods when they have a variety of methods available to them, and the reality is that not every method is going to work for every woman,” Rebecca Simmons, PhD, Research Assistant Professor, Department of Obstetrics and Gynecology, University of Utah, told Health. “This is really exciting, in the sense that the more methods we have, the more likely it is that people can find something that works for them—and then can avoid unwanted pregnancy.”
Apple, headquartered in Cupertino, Calif., received FDA clearance in 2018 for an electrocardiogram (ECG) app for its Apple Watch Series 4 that allows users to take an ECG from their wrist to detect irregular heart rhythms and atrial fibrillation (AFIB).
“The role that technology plays in allowing patients to capture meaningful data about what’s happening with their heart—at the moment when it’s happening, like the functionality of an on-demand ECG—could be significant in new clinical care models and shared decision-making between people and their healthcare providers,” said Nancy Brown, CEO of the American Heart Association, in a press release.
Patients, Providers, and Big Pharma All Like Digital
Therapeutics
There is some evidence that patients and healthcare
providers are intrigued and willing to try digital therapeutics. In a PwC HRI survey,
more than 50% of respondents said they “would be somewhat or very likely to try
an FDA-approved app or online tool for treatment of a medical condition.”

Pharmaceutical companies also are interested in digital therapeutics. A 2018 PwC HRI survey found that 80% of pharmaceutical executives had plans to invest in digital therapeutics in the near future.
With precision medicine and pharmacogenetics, clinical laboratories
could play an essential role in supporting digital therapeutics in the future. But
to truly be competitive in this space and take advantage of the opportunity, medical
laboratories will need to increase their information technology and digital
capabilities.
It has been regularly demonstrated in recent decades that human breath contains elements that could be incorporated into clinical laboratory tests, so the decision to use this “breath biopsy” test in a therapeutic drug trial will be closely watched
When a major pharma company pays attention to a breath test, implications for clinical laboratories are often forthcoming. Such may be the case with GlaxoSmithKline (GSK). The global healthcare company has selected Owlstone Medical’s Breath Biopsy technology for use in its Phase II clinical trial of danirixin (DNX), a respiratory drug under development by GSK for treatment of chronic obstructive pulmonary disease (COPD), an Owlstone Medical news release announced.
Anatomic pathologists and medical laboratory leaders will be intrigued by GSK’s integration of breath-based specimens in a clinical trial of a respiratory drug. The partners in the trial aim to analyze breath samples to better understand the drug’s treatment effects and to discover personalized medicine (AKA, precision medicine) opportunities.
GSK (NYSE:GSK), headquartered in the UK but with a large presence in the US, researches and develops pharmaceutical medicines, vaccines, and other consumer health products.
Owlstone Medical, a diagnostic company, is developing a breathalyzer for disease and says it is on a mission to save 100,000 lives and $1.5 billion in healthcare costs. Dark Daily previously reported on Owlstone Medical’s Breath Biopsy platform. The Cambridge, England-based company has raised significant funding ($23.5 million) and already garnered credible cancer trial collaborators including the UK’s National Health Service (NHS).
Now, Owlstone Medical has brought its breath analysis technology to bear on chronic disease outside of cancer diagnostics development. A pharmaporum article called Owlstone’s Medical’s work with GSK an “additional boost of confidence” in the company’s technology, as well as a means for revenue.

GSK Studying Future Treatments for Respiratory Diseases
COPD affects about 700 million people worldwide, an increase of about 65% since 1990, GSK pointed out. In September 2017, GSK presented respiratory disease data and its pipeline medications at the European Respiratory Society in Milan, Italy. Included was information on danirixin (an oral CXCR2 antagonist), which is part of the company’s focus on COPD disease modification, according to a GSK news release.
“Each of our studies sets the bar for our future research and innovation,” noted Neil Barnes, MA Cantab, FRCP, FCCP(Hon), Vice President, Global Franchise Medical Head, GSK Respiratory, in the GSK press release.
Clinical Trial Aimed at Identifying the ‘Right’ Patients
With Owlstone Medical’s breathalyzer, GSK plans to explore how volatile organic compounds (VOCs) can help identify patients who will benefit most from the company’s medications, as well as evaluate Danirixin’s effects. A critical element of personalized medicine.
“It’s part of our efforts to identify the right patient for the right treatment,” said Ruth Tal-Singer, PhD, GSK’s Vice President of Medicine Development Leader and Senior Fellow, Respiratory Research and Development, in the Owlstone Medical news release.
VOCs in breath will be captured in a non-invasive way from patients who wear Owlstone Medical’s ReCIVA Breath Sampler, which, according to Owlstone Medical, has CE-mark clearance, a certification noting conformity with European health and safety standards. The VOCs breath samples will then be sent to Owlstone Medical’s lab for high-sensitivity analysis.
“Non-invasive Breath Biopsy can establish a role in precision medicine applications such as patient stratification and monitoring treatment response,” said Billy Boyle, Owlstone Medical’s co-Founder and Chief Executive Officer.
VOC Biomarkers in Respiratory Disease
VOC profiles can be characteristic of COPD as well as other respiratory diseases including asthma, tuberculosis, and cystic fibrosis, reported Science/Business.
According to Owlstone Medical’s Website, VOCs are gaseous molecules produced by the human body’s metabolism that are suitable for Breath Biopsy. Their research suggests that exhaled breath reflects molecular processes responsible for chronic inflammation. Thus, VOCs captured through Breath Biopsy offer insight into respiratory disease biomarkers.
Breath also includes VOCs that originate from circulation, which can provide information on a patient’s response to medications.
How the Breath Biopsy Platform Works
Owlstone Medical’s platform relies on its patented Field Asymmetric Ion Mobility Spectrometry (FAIMS) technology, which “has the ability to rapidly monitor a broad range of VOC biomarkers from breath, urine and other bodily fluids with high sensitivity and selectivity,” according to the company’s website. During the process:
Gases are exchanged between circulating blood and inhaled fresh air in the lungs;
VOC biomarkers pass from the circulation system into the lungs along with oxygen, carbon dioxide, and other gases;
Exhaled breath contains exiting biomarkers.
It takes about a minute for blood to flow around the body. So, a breath sample during that time makes possible collection and analysis of VOC biomarkers from any part of the body touched by the circulatory system.
The medical analysis is enabled by software in the Owlstone Medical lab, Boyle told the Cambridge Independent.
“There’s an analogy with blood prints—you get the blood and can look for different diseases, and we’ve developed core hardware and technology to analyze the breath sample,” he said.
Another Breath Sample Device
The ReCIVA Breath Sampler is not the only breathalyzer focused on multiple diseases. Dark Daily reported on research conducted by Technion, Israel’s Institute of Technology, into a breath analyzer that can detect up to 17 cancers, and inflammatory and neurological diseases.
But Owlstone Medical stands out due, in part, to its noteworthy partners: the UK’s National Health Service, as well as the:
And now the company can add collaboration with GSK to its progress. Though some question the reliability of breath tests as biomarkers in the areas of sensitivity and specificity required for cancer diagnosis, Owlstone Medical appears to have the wherewithal to handle those hurdles. It is a diagnostics company that many pathologists and medical laboratory professionals may find worth watching.
Examples already exist of manufacturers agreeing to refund payments if their therapeutic drugs don’t benefit patients; Medical laboratories with proprietary tests may find this strategy effective at guaranteeing the clinical utility of their assays
If their medical devices, medical laboratory tests, or prescription drugs are not effective, will payers, patients, and doctors get refunds from the manufacturers of these products? Some experts predict that the increased emphasis on improved patient outcomes, and the need for healthcare enterprises to back up the clinical value of their services, could lead to money-back guarantees and reimbursements for treatment therapies.
Offering a refund for services if the patient does not benefit is a powerful and compelling way for a company to call attention to its confidence level in its products and services. (more…)
Pathologists take note: 80% of physicians will be using mobile technology by 2012
Meet “mHealth!” That’s the new term to describe how mobile devices are used in the delivery of healthcare to patients. Many clinical laboratories and pathology groups already have laboratory informatics solutions that support how their client physicians use mHealth solutions in patient care.
Experts predict that Smartphones will dominate mobile healthcare (mHealth) in just a few short years. The enabling tools will be mobile applications (apps) that monitor such conditions as diabetes, hypertension, coronary heart disease and asthma. Smart phones will also be used to order medical laboratory tests and access clinical laboratory test data. (more…)
Pharmaceutical Companies Partnering with IVD Manufacturers to Develop Companion Diagnostic Tests for their Therapeutic Drugs
Growing acceptance of companion diagnostics is a trend with the potential to greatly increase the value that clinical pathology laboratory testing delivers to physicians, patients, and payers. In 2010, it was increasingly common to see a pharmaceutical company announce an agreement with an in vitro diagnostics (IVD) manufacturer to develop a companion diagnostic test specifically for a therapeutic drug under development by that pharmaceutical company.
As most pathologists and clinical managers know, use of a companion diagnostic test is expected to add precision to the physician’s decision to prescribe therapeutic drugs. Thus, the increased number of public announcements during 2010 about companion diagnostic test development deals involving a pharmaceutical company and an IVD manufacturer indicates this trend is establishing solid roots.
