Spinout BioCaptiva Aims to Unlock Blood-based Biopsies

A University of Edinburgh spinout company aims to revolutionise the early diagnosis of difficult-to-detect cancers with a new blood-based biopsy device.

With Edinburgh Innovations’ support, BioCaptiva has been launched with more than £1 million in seed investment from Edinburgh-based investment syndicate Archangels and Scottish Enterprise.
BioCollector device

It has developed a next-generation “liquid biopsy” technology that captures circulating free DNA (cfDNA) from patients’ blood in much greater quantities than is possible through the current standard of a single blood draw, overcoming a significant current limitation of cancer liquid biopsy testing.

Named BioCollector, the device works alongside a standard apheresis machine, filtering cfDNA from the patient’s blood system.

BioCollector is based on a decade of research led by Professor Tim Aitman, Director of the Centre for Genomic and Experimental Medicine, and Professor Mark Bradley of the University’s School of Chemistry.

“I’m delighted that after several years of work with colleagues in Edinburgh, we will now progress towards first-in-human trials. BioCollector will provide a step change in the capabilities of liquid biopsy for cancer detection and diagnosis.

“We are excited to be moving our device into this market with its huge potential for advances in the care of patients with cancer.”

Prototype promise

Prototypes indicate the potential to detect early-stage cancers in patients without the need for surgical biopsy. The BioCollector also promises new approaches for monitoring minimal residual disease and detecting disease recurrence, resulting in better patient outcomes.

The seed investment will enable BioCaptiva to carry out its first trials to prove its safe use in humans. Should the technology prove successful, BioCaptiva plans to scale up its technology ahead of regulatory clinical trials, scheduled for completion during 2024.
Global market

A recent report shows the global liquid biopsy market growing by a compound annual rate of 33% and projected to be worth more than $6 billion by 2025.

BioCaptiva expects interest to come principally from companies that are developing novel cancer tests limited by current methods of extracting cfDNA, where the higher yield achieved by the BioCollector will increase the sensitivity of their detection methods.

“BioCaptiva has very exciting prospects in an important field, based on the leading research of Edinburgh scientists.

“The launch of this company, with such solid investment support, promises to improve many people’s lives.”
