EndoDrill® is the first market-cleared electric-driven biopsy instrument for endoscopy in the US and Europe

EndoDrill® – a groundbreaking, market-cleared
biopsy method for enabling EUS-CNB

EndoDrill® instruments work with precision to take high-quality tissue samples with the aim of improving diagnostics for several types of cancer, such as stomach, pancreatic, liver, lung and bladder cancer. The innovative product technology redefines the growing area of endoscopic ultrasound-guided tissue acquisition for cancer diagnostics. The motorised high-speed rotational EndoDrill® needle enables high-quality core biopsies, overcoming the limitations of today’s standard manual needles.

In 2023, EndoDrill® GI, BiBB’s lead product, received market clearance from the US FDA as the first electric-driven biopsy instrument for endoscopy in the USA. At the beginning of 2024, CE certification according to MDR was obtained in Europe for the entire EndoDrill® product family. The EndoDrill® system has been designed to be easy to use consisting of a sterile disposable EndoDrill® Biopsy Instrument with an associated EndoDrill®Drive System.

An initial clinical pilot study, EDMX01, showed 100% diagnostic accuracy when analysing samples taken with EndoDrill® GI.

EndoDrill® / Technology

Electric-driven rotation is the key to improved biopsies

Unlike conventional manual needle instruments, the FDA-cleared EndoDrill® uses an electric-driven drill cylinder. The design enables deep sampling with high precision. One or more high-quality and solid core biopsies are drilled out – a requirement for complete histological diagnosis, staging and genetic analysis.

EndoDrill® consists of a biopsy instrument with flexible drill cylinder (disposable) and a drive system (reusable) with associated motor unit, foot pedal and drive cable. EndoDrill® has been developed to collect tissue samples of the highest possible quality during ultrasound-guided endoscopic examinations (EUS/EBUS).

How does the EndoDrill® system work?

  • EndoDrill® Motor Unit

    A compact motor unit is connected to the EndoDrill® Drive Cable and controlled via the EndoDrill® Foot Pedal (On/Off). The motor generates rotation that is transferred to the EndoDrill® Drive Cable and on to the needle cylinder of the disposable EndoDrill® Biopsy Instrument.

  • Rotating Needle Cylinder

    EndoDrill’s electric rotating needle cylinder cuts solid core biopsies with high precision for maximum diagnostic accuracy. The inner flexible needle cylinder is protected by an outer sheath.

  • EndoDrill® Drive Cable

    The EndoDrill® Drive Cable transmits rotation from the EndoDrill® Motor Unit to the inner needle cylinder of the EndoDrill® Biopsy Instrument.

  • EndoDrill® Biopsy Instrument (disposable)

    Intuitive EUS sampling handle, including locking screws, with flexible internal rotating needle cylinder and external protective sheath.

  • EndoDrill® Foot Pedal (reusable)

    The EndoDrill® Foot Pedal is used to control motor rotation (On/Off)

Overcoming the limitations of today’s biopsy needles

Today’s manual EUS/EBUS needle instruments are inserted into the tumour with a repeated stabbing motion, and detached cells and tissue fragments adhere to the tip of the needle. The method requires experienced endoscopists for sampling and skilled pathologists for evaluation. To increase the chances of the fragmented cell material leading to a diagnosis, it is not uncommon to use a variety of supplemental methods, such as having a pathologist in the operating room for Rapid On-Site Evaluation (ROSE), centrifuging the sample (i.e. cellblock), taking multiple samples at different sites, and using different techniques to aspirate the cell sample. EndoDrill® simplifies the entire diagnostic process. Instead of manual sampling with a stabbing motion, samples are taken with the help of electric-driven and user-friendly precision drilling.

 

The new era of personalised cancer treatment requires more high-quality core biopsies for histological diagnosis and genetic analysis.

With a flexible rotating needle cylinder, the endoscopist cuts out fine core samples without blood contamination, while maintaining tissue architecture under high precision. Sampling with EndoDrill® becomes more reproducible and standardised, i.e. less dependent on the experience and skill of the endoscopist.

Another very important and unique feature is the ultra-flexible design, which enables sampling with a highly angled. This means that high-quality samples can be taken from very hard-to-reach tumours, which is often technically challenging with today’s more rigid biopsy needles.

 

Ultraflexible needle provides easy access even to difficult anatomical locations.

Using the new EndoDrill® high-quality core needle biopsy (CNB) at the first examination makes it possible to achieve the goal of a treatment-determining diagnosis immediately, while avoiding resource-intensive methods and repeated sampling. Early definitive diagnosis with histological and genetic information enables personalised treatment to be initiated immediately, which can save both lives and healthcare resources.

From EUS tissue sampling with fine-needle aspiration of cells (EUS-FNA) of the 2000s to fine-needle biopsy (EUS-FNB) of tissue fragments of the 2010s, introduction of the electric EndoDrill® is the 2020s’ solution for the sampling of high-quality core needle biopsies (EUS-CNB). It is a long-awaited improvement in diagnostics for many types of cancer, with the potential to eventually establish a new standard of care for endoscopic sampling.

EndoDrill® / Product portfolio

Next generation electric biopsy instruments

BiBB is currently developing and manufacturing three product variants of EndoDrill® that can be used for endoscopic tissue sampling in six of the ten most common forms of cancer. The EndoDrill® products are compatible with endoscopes from the major manufacturers and consist of sterile EndoDrill® Biopsy Instruments connected to EndoDrill®Drive System.

The various biopsy instruments of the product portfolio are adapted to each application’s specific requirements and environment. EndoDrill® GI (gastrointestinal tract) and EndoDrill EBUS (airways/lung) are used with ultrasound endoscopes, while EndoDrill® URO (urinary tract) is used with a conventional cystoscope. The motorised EndoDrill® Drive System is used for all biopsy instruments.

EndoDrill® EBUS

EndoDrill® EBUS is used in the respiratory tract in endobronchial ultrasound (EBUS) sampling for the diagnosis and staging of lung cancer. As more and more targeted treatments are available, the demands on the quality of diagnostic tissue samples increase and today’s fine-needle instruments do not fully live up to expectations. EndoDrill® EBUS has been designed to meet the new requirements for histopathological and genetic analyses. With the right diagnosis, you can start the right treatment even in severe cases.

EndoDrill® EBUS is used in the respiratory tract in endobronchial ultrasound (EBUS) sampling for the diagnosis and staging of lung cancer.

EndoDrill® URO

EndoDrill® URO is used with a standard cystoscope for sampling of muscle-invasive bladder cancer (MIBC). The purpose of EndoDrill® URO is to take tissue samples of deep-growing bladder tumors for the first time already at the initial cystoscopy. With an earlier diagnosis, today’s invasive surgical procedures (TURB) could be avoided and the treatment of patients with MIBC could be started earlier. An initial pilot study shows that EndoDrill® URO safely can take treatment-based samples earlier in the care chain if MIBC is suspected.

EndoDrill® / Clinical studies

Positive results for EndoDrill®

In preclinical trials and clinical pilot studies, BiBB compared EndoDrill® with market-leading competitors (EUS-FNB). The results show that EndoDrill® takes tissue samples of higher diagnostic quality than equivalent samples taken with EUS-FNB.

 

Study EDMX01 with EndoDrill® GI

In the autumn of 2020, the first clinical study, EDMX01, was initiated at three Swedish university hospitals for sampling hard-to-diagnose upper gastrointestinal cancer (SEL tumours).

The analysis showed that EndoDrill® safely collected high-quality tissue samples, known as core biopsies, even in comparison with leading fine needle biopsy instruments (EUS-FNB). The study was presented in May 2022 at the DDW congress in San Diego, USA,

The study was presented in May 2022 at the DDW congress in San Diego, USA, and published in the peer reviewed Scandinavian Journal of Gastroenterology in March 2024. BiBB plans to initiate further clinical studies to systematically follow up on how the product works in clinical use.

Study EDUX02 with EndoDrill® URO

BiBB has another ongoing study programme for the urinary tract that involves tissue sampling with EndoDrill® in a standard endoscope for muscle-invasive bladder cancer (MIBC), i.e. tumours that have grown through the bladder mucosa and muscle. An initial clinical study on ten patients was completed in 2022, and the results were published in the journal European Urology Open Science in June 2023. The study shows that EndoDrill® URO can safely take treatment-determining samples earlier in the care chain when muscle-invasive bladder tumours are suspected. The research team concludes that there is reason to follow up the pilot study with a randomised efficacy study, which is planned and has received regulatory approval. The project also includes a health economic analysis.

The urologists’ long-term aim with the clinical programme is to demonstrate that early sampling with EndoDrill® can replace today’s standardised sampling as part of what is known as a TURBT procedure. The hypothesis is that the lead time from sampling to treatment start can be significantly reduced, which can improve survival for this serious type of tumour.
