Doctors diagnose as many as 60,000 new cases of Parkinson’s disease (PD) every year in the United States. Yet diagnosing PD with certainty can take years — long after early signs and symptoms have appeared.
The Israeli startup BioShai has a game-changing product on the horizon: PDx, the world’s first simple blood test for the early diagnosis of PD.
The test results can be combined with clinical data, providing a more accurate diagnosis to help physicians decide on the best course of treatment at a much earlier stage.
More than 10 million people worldwide are living with this chronic and progressive movement disorder caused by the malfunction and death of neurons that produce dopamine, a chemical that coordinates the brain’s control of movement and coordination.
“Having a diagnosis at an earlier stage can lead to a more precise treatment and a higher quality of life for the patient,” says BioShai CEO Jennifer Yarden, who has a PhD in medical science and formerly was responsible for clinical and commercial development of diagnostic assays and kits at Glycominds. Yarden is also CEO and cofounder of Curewize Health.
“Offering a simple and inexpensive test for the diagnosis of Parkinson’s is considered essential for the development of neuroprotective therapy,” she explains, “because by the time a patient has the many movement symptoms associated with Parkinson’s, a majority of the dopamine-producing neurons are lost or become impaired by the disease.”
Research in Technion lab
The PDx blood test, which measures changes in particular molecules known to be associated with Parkinson’s, will be available through an Israeli lab on a limited beta basis in early 2017. BioShai will soon apply for regulatory approval in Europe.
BioShai was founded in January 2014 in the Youdim Pharmaceuticalsincubator in Yokneam Illit. Technion Prof. Moussa Youdim, (one of the inventors of the Parkinson’s drug Azilect) cofounded BioShai, which currently has four employees.
Youdim and University of Würzburg Prof. Peter Riederer performed pioneering research, published in 2010 and 2012, revealing that measuring the expression level of specific genes in blood could detect PD with a high level of accuracy. BioShai grew out of this discovery.
Cofounder and CMO Dr. Martin Rabey, a neurologist originally from Argentina, is a professor emeritus at Tel Aviv University’s Sackler School of Medicine and an international expert in Parkinson’s and Alzheimer diseases. He and European neurologists developed the Simple Parkinson Evaluation Scale (SPES), a practical tool for the evaluation of PD patients.
