What drives the therapy selection test market?

Clarivate medtech expert Sophia Quraishi reviews key factors driving increased demand for premium-priced therapy selection tests.


Therapy selection tests are a form of liquid biopsy, which involve sequencing substrates isolated from bodily fluids, such as blood, saliva or urine. This approach is less invasive, can be used more often and is more cost effective than tests involving tissue sampling through invasive procedures like surgery.

Once a fluid sample is collected, substrates—including circulating tumor cells, circulating free DNA, circulating tumor DNA or exosomes—are isolated, and further sample purification and extraction is conducted to prepare the sample for sequencing and analysis.

In the case of therapy selection liquid biopsy tests, the results inform extremely specific treatment decisions. For example, a test can assess a patient for the presence of a specific genetic mutation that would indicate that their cancer is likely to respond to a particular targeted therapy.

Several factors are driving increased demand for premium-priced therapy selection tests, including the shift toward value-based care, the proliferation of orphan drugs and ongoing R&D.


Market drivers include:


Value-based care and reimbursement

Value-based care models are outcome-oriented and focus on the entire patient pathway.

As a result, they place increased emphasis on personalized medicine, including the ability to not only detect cancers early but also to identify an appropriate targeted therapy that will best benefit the patient. Early detection and the identification of a treatment method with the greatest likelihood of success for a patient have the potential to improve outcomes, enable less costly interventions and reduce the need for retreatment and downstream costs of care.

In the United States, for example, recent updates to Medicare, including the rollout of programs such as Medicare Advantage and specialty tier drug spending under Section D, have been driving the transition toward value-based care. They thereby support the uptake of personalized medicine, including liquid biopsy tests like those used for therapy selection.

As a result, market expansion is not only being backed by increasing sophistication in diagnostic and sequencing technology, but also by reimbursement policies in some countries that ensure widespread market access and accessibility for these in vitro diagnostic and laboratory-developed tests.


Proliferation of orphan drug development

Therapy selection tests can identify actionable biomarkers that uniquely correspond to one or more orphan drugs. Because of this capability, therapy selection tests have the ability to enhance treatment decisions for advanced cancer patients.

As result, as more orphan drugs are developed, demand for therapy selection tests will rise with little risk of market cannibalization between therapy selection tests.


Development partnerships and increased commercialization

Therapy selection tests and companion diagnostics have traditionally been developed using tissue-based samples. The field of liquid biopsy therapy selection tests is still nascent in terms of research and development.

Moving forward, an increasing number of key industry partnerships will center on the development of companion diagnostics, enhancing the rate at which the field of therapy selection develops. Recent partnership and collaboration announcements include:

In addition, other upcoming entrants to the market, such as Exosome Diagnostics—which now benefits from parent company Bio-Techne’s resources—continue to develop companion diagnostics.

Overall, the therapy selection test market represents a highly innovative space with several competitors developing products that have the potential to greatly improve patient experience and treatment outcomes. The market is also expected to (Clarivate, 2020), making this a key liquid biopsy market area to watch.
