Boston Children’s Hospital ShuntCheck® Clinical Study Published in "Neurosurgery"

YARDLEY, PA  July 2, 2018 – The results of a clinical study conducted by Drs. Mustafa Q. Hameed, Joseph R. Madsen and their colleagues at Boston Children’s™ Hospital was published in Neurosurgery (Neurosurgery 0:1-10, 2018).  A summary of the article can be found at https://doi.org/10.1093/neuros/nyy246​.

This single-center, 71 subject study found that ShuntCheck, which uses thermal dilution technology to detect flow in the CSF shunts of hydrocephalus patients, had a 94.2% Negative Predictive Value in ruling out the need for shunt revision surgery.  Importantly, the three “false negative” surgery patients did not have obstructed shunts – one was a case of symptomatic over-drainage, another required valve replacement following mechanical failure of an adjustable shunt, and the third required repair of a detached Rickham reservoir.  ShuntCheck therefore demonstrated 100% Sensitivity and 100% Negative Predictive Value for ruling out shunt obstruction.

The Boston study preceded and informed the prospective, multi-center ShuntCheck Pediatric Outcomes Study.  The multi-center study, which was reported at the AANS Plenary Session, also found that ShuntCheck, when used in conjunction with physician judgment or imaging results, was 100% accurate in ruling out shunt obstruction.  The study concluded that ShuntCheck can reduce the need for CT Scans, Admissions for Observation and invasive testing in symptomatic pediatric hydrocephalus.

“We thank Drs. Hameed and Madsen and their colleagues for their dedication to this study,” said Frederick J. Fritz, NeuroDx founder and CEO. “These results and the results of the larger ShuntCheck Pediatric Outcomes Study support the use of ShuntCheck as a confirmatory Rule Out test for symptomatic pediatric hydrocephalus patients,” he said.

ShuntCheck® Pediatric Outcomes Study Results Presented at AANS Plenary Session

CHICAGO IL May 5, 2016 – Dr. David M. Frim, Chief of Neurosurgery at The University of Chicago Medical Center and a Principal Investigator of the ShuntCheck Pediatric Outcomes Validation Study, presented final study findings in a Plenary session at the American Academy of Neurological Surgeons (AANS) annual conference.

ShuntCheck, a non-invasive test for CSF flow in shunted hydrocephalus patients, achieved its clinical study endpoints. The prospective, blinded multi-center study demonstrated that ShuntCheck was equal to neuroimaging in ruling out shunt obstruction in symptomatic pediatric patients clinically judged “unlikely to require surgery” and showed that concordant ShuntCheck-plus-Imaging results were more accurate than Imaging-alone results.

“Our study indicates that ShuntCheck can reduce the need for CT Scans, Admissions for Observation and invasive testing in symptomatic pediatric hydrocephalus,” said Dr. Frim. “I should disclose that I was a skeptic when I first heard of the ShuntCheck technology but I must be true to the data and admit that my concerns were unfounded.”

“ShuntCheck was honored to be chosen for a Plenary presentation. 1500 abstracts were submitted to the AANS but only 13 were chosen for the Plenary. We thank Dr. Frim and Dr. Joseph Madsen for preparing the winning abstract and Dr. Frim for presenting study findings,” said Frederick J Fritz, NeuroDx founder and CEO. “Positive study results support the use of ShuntCheck as a first line diagnostic test in Children’s Hospitals,” he said.

ShuntCheck® Principal Investigator Presents Favorable Interim Clinical Results

PRINCETON, NJ January 14, 2016 – Dr. Joseph R. Madsen, Pediatric Neurosurgeon at Boston Children’s Hospital and the Principal Investigator of the ShuntCheck Pediatric Outcomes Validation Study, presented interim findings (280 patients) at the American Society of Pediatric Neurosurgeons (ASPN) annual meeting.

ShuntCheck, which uses thermal dilution technology to detect flow in the CSF shunts of hydrocephalus patients, achieved its two clinical study endpoints. The prospective, blinded multi-center study demonstrated that ShuntCheck was equal to neuroimaging in ruling out shunt obstruction in symptomatic pediatric patients clinically judged “unlikely to require surgery”. It also showed that concordant ShuntCheck-plus-Imaging results were superior to Imaging results.

“These results suggest that adding ShuntCheck to the shunt malfunction diagnostic protocol can reduce the need for CT Scans, Admissions for Observation and invasive tests” said Dr. Madsen.

“We are very grateful to Dr. Madsen for his leadership and to investigators at nine other US Children’s Hospitals for their dedication to this study,” said Frederick J Fritz, NeuroDx founder and CEO. “These positive interim results support the use of ShuntCheck as a diagnostic tool for physicians who care for children with hydrocephalus,” he said.

NIH Awards $1 Million Grant to Develop ShuntCheck® Shunt Flow Monitor

BENSALEM, PA, April 1, 2013 – NeuroDx Development has been awarded a $1 million, 2-year Phase II SBIR grant by the National Institute of Neurological Disorders and Stroke, a division of the National Institutes of Health (NIH), to support product development of Continuous Real Time ShuntCheck, an advanced version of the ShuntCheck thermal dilution test which allows for continuous monitoring of cerebrospinal fluid (CSF) shunt flow in hydrocephalus patients.

Hydrocephalus is a condition in which CSF accumulates in the brain. It is corrected by placing a shunt that drains excess CSF to the abdomen. Shunts frequently malfunction, potentially leading to brain damage and death. Diagnosis of shunt malfunction is expensive and presents risks such as exposure to radiation from CT Scans. Additionally, the clinical management of shunted patients is complex due to a lack of tools for investigating shunt function.

“Continuous Real Time ShuntCheck is like a ‘Holter Monitor’ for shunts, allowing physicians to monitor shunt flow over an extended period of time,” said NeuroDx founder and CEO, Frederick J Fritz. “Our clinical advisors have indicated that shunt flow monitoring will be useful in investigating a number of shunt function issues such as suspected overdrainage.”

“We are very grateful for NIH support for this project, allowing us to develop a new technology which can help physicians care for their hydrocephalus patients,” he said.

NeuroDx Development Awarded NIH Grant to Develop ICPCheck™

BENSALEM, PA, October 15, 2012 – The National Institute of Neurological Disorders and Stroke, a division of the National Institutes of Health (NIH), has awarded a Phase I SBIR grant to NeuroDx Development to support the development of ICPCheck™, the first long term implantable, non-invasively readable intracranial pressure (ICP) monitor for hydrocephalus patients.

Hydrocephalus is a condition in which CSF accumulates in the brain. It is corrected by placing a shunt that drains excess CSF to the abdomen. Shunts frequently malfunction, usually by obstruction, leading to a life-threatening elevation of pressure in the brain. Diagnosis of shunt malfunction is expensive and presents risks such as exposure to radiation from CT Scans, and clinical management of shunted patients is complex due to a lack of tools for investigating shunt function.

“There are currently no non-invasive, non-radiologic technologies for detecting elevated ICP caused by shunt malfunction,” said NeuroDx founder and CEO, Frederick J Fritz. “ICPCheck, which will be placed during shunt surgery and can be interrogated non-invasively thereafter, will provide an important new clinical tool for investigating a number of shunt function issues. We are very grateful for NIH support for this project, allowing us to develop a new technology which can help physicians care for their hydrocephalus patients,” he said.

NeuroDx Development Awarded $3 Million NIH Grant for ShuntCheck Test

BENSALEM, PA, July 1, 2011 – NeuroDx Development has been awarded a $3 million, 3-year Phase II SBIR grant by the National Institute of Neurological Disorders and Stroke, a division of the National Institutes of Health (NIH), to support product development and clinical trials of the company’s non-invasive test of shunt function in hydrocephalus patients, ShuntCheck.

Hydrocephalus, a condition in which cerebrospinal fluid (CSF) accumulates in the brain, potentially leading to brain damage and death, affects 300,000 Americans and is associated with $2 billion in annual US healthcare costs. It is corrected by placing a shunt that drains excess CSF to the abdomen. Shunts frequently malfunction, usually by obstruction, but the symptoms of shunt failure are non-specific (headache, nausea). Diagnosis of shunt malfunction by conventional means is difficult, expensive, and associated with risks to the patient such as repeated exposure to radiation from CT Scans.

ShuntCheck was developed to provide an alternative method for testing shunt function, using thermal dilution technology to detect CSF flow in the shunt.  Initial clinical testing of ShuntCheck identified that shunts do not flow continuously, so ShuntCheck tests conducted during temporary periods of no-flow incorrectly suggest shunt problems.  To address this, NeuroDx developed the Micro-Pumper™, a non-invasive device which generates a temporary increase in CSF flow in patent, but not in occluded, shunts.  ShuntCheck can detect this increase in CSF flow and differentiate between flowing and blocked shunts.

NeuroDx founder and CEO, Frederick J Fritz, commented “This NIH grant will enable us to complete the development of Micro-Pumper and to conduct a multi-center clinical study to assess the accuracy and clinical utility of the ShuntCheck-Micro-Pumper test.  NeuroDx will undertake the study with collaborators at Children’s Hospital Boston, Johns Hopkins Hospital, University of Chicago Comer Children’s Hospital, Miami Children’s Hospital and LeBonheur Children’s Hospital.

“We are very grateful for NIH support for this project, which will allow us to bring forward an important clinical tool for the care of hydrocephalus patients” he said.

NIH Awards Grant to Develop Continuous Real Time ShuntCheck® Test

BENSALEM, PA, April 22, 2011 – The National Institute of Neurological Disorders and Stroke, a division of the National Institutes of Health (NIH), has awarded a Phase I SBIR grant to NeuroDx Development to support the development of Continuous Real Time ShuntCheck, an advanced version of the ShuntCheck thermal dilution test which allows for continuous monitoring of cerebrospinal fluid (CSF) shunt flow in hydrocephalus patients.

Hydrocephalus is a condition in which CSF accumulates in the brain. It is corrected by placing a shunt that drains excess CSF to the abdomen. Shunts frequently malfunction, potentially leading to brain damage and death. Diagnosis of shunt malfunction is expensive and presents risks such as exposure to radiation from CT Scans, and clinical management of shunted patients is complex due to a lack of tools for investigating shunt function.

“Our first generation ShuntCheck only partially addresses this clinical need because it provides a five minute “snap shot” assessment of CSF shunt flow.” said NeuroDx founder and CEO, Frederick J Fritz.  “Continuous Real Time ShuntCheck will monitor shunt flow over an extended period of time – like a “Holter Monitor” for shunts.  Our clinical advisors have indicated that shunt flow monitoring will be useful in investigating a number of shunt function issues.”

NIH Awards Grant to Support ShuntCheck® Clinical Study

BENSALEM, PA, March 21, 2011 – The National Institute of Neurological Disorders and Stroke, a division of the National Institutes of Health (NIH), has awarded a Phase I SBIR grant to NeuroDx Development to support a clinical study of ShuntCheck in Normal Pressure Hydrocephalus (NPH) patients.

NPH, a buildup of cerebrospinal fluid (CSF) in the brain, afflicts an estimated 700 thousand older adults in the US, causing gait impairment, urinary urgency and incontinence. It is corrected by placing a shunt that drains excess CSF to the abdomen. Shunts frequently malfunction, leading to the insidious return of the original symptoms over an interval of weeks to months, making shunt failure challenging to diagnose. Suspected shunt failure in NPH patients is typically investigated using a radionuclide shunt patency study, an invasive and expensive procedure which carries the risk of infection.

ShuntCheck was developed to provide an alternative method for testing shunt function, using thermal dilution technology to detect CSF flow in the shunt.

“This NIH grant funds a clinical study which will compare ShuntCheck with the radionuclide shunt patency study in assessing shunt function in NPH patients” said Frederick J Fritz, NeuroDx founder and CEO.  “If the study demonstrates that ShuntCheck provides comparable accuracy, it will support clinical use of our non-invasive option to the current gold standard” he said.  NeuroDx will undertake the study with Michael A. Williams MD FAAN and his colleagues at Sinai Hospital of Baltimore.

“We are very grateful for NIH support for this study, which will provide important information to neurosurgeons who care for Normal Pressure Hydrocephalus patients” he said.

NeuroDx Development Awarded NIH Grant for ShuntCheck® Test

BENSALEM, PA, May 6, 2010 – NeuroDx Development has been awarded a 2-year Phase I SBIR grant by the Eunice Kennedy Shriver National Institute of Child Health & Human Development, a division of the National Institutes of Health (NIH), to support product development and clinical testing of ShuntCheck, the company’s non-invasive test of shunt function in hydrocephalus patients.

Hydrocephalus is a condition in which cerebrospinal fluid (CSF) accumulates in the brain, potentially leading to brain damage and death. It is corrected by placing a shunt that drains excess CSF to the abdomen. Shunts frequently malfunction, usually by obstruction, a life threatening medical condition. Shunt malfunction in children is usually diagnosed by a CT Scan of the brain.  Repeated exposure to radiation from CT Scans has been a growing concern for pediatric neurosurgeons,

This concern was the driving force for the development of ShuntCheck as an alternative method for testing shunt function, using thermal dilution technology to detect CSF flow in the shunt.

Frederick J Fritz, NeuroDx founder and CEO, commented “This NIH grant supports important product development and clinical validation work including a clinical study comparing ShuntCheck with an MRI-based test of shunt flow, a study of shunt flow intermittency and the development and initial testing of “Micro-Pumper”, a non-invasive device which temporarily increases shunt flow and which will be used in conjunction with ShuntCheck.  NeuroDx will collaborate with Joseph R, Madsen MD and his colleagues at Children’s Hospital Boston on this program.”

“We are very grateful for NIH support for our work to create clinical tools for the care of children with hydrocephalus” he said.

NeuroDx Development Wins Small Business Research Grant
NeuroDx Development received a $143,000 Small Business Innovation Research Grant Monday to continue its development of improved diagnostic tests for children and adults with brain injuries and diseases.

The Bensalem, Pa., company plans to use the funding to help improve the treatment of patients with hydrocephalus, which is essentially “water in the brain” that can exist because of a birth defect or as the result of brain injury.

Patients with hydrocephalus are treated with an implanted shunt that drains fluid from their brain. The shunts, however, eventually fail. That failure currently can only be detected by a CAT scan and repeated CAT scans expose patients to additional levels of radiation.

NeuroDx is developing a non-invasive, alternative method to test that a shunt is still functioning properly, without exposing a patient to potentially harmful levels of radiation. The company is also developing a device to help doctors diagnose brain injury by non-invasively measuring intracranial pressure.

“This grant supports the vital research that NeuroDx is conducting to help those suffering from this brain condition, as well as supporting employment in this cutting-edge field,” said U.S. Rep. Patrick Murphy, D-Bucks, who helped the company secure the funding. “The work they are doing will improve the treatment safety for the 1.4 million Americans who currently suffer from traumatic brain injury every year.
