The Evolution of Drug Testing: Beyond Animal Models
As the global population continues to struggle with the increasing prevalence of neurological and psychiatric disorders—impacting nearly 3.4 billion people worldwide—the traditional methods of drug development are proving insufficient. Despite their popularity, animal models, especially mice, have a mere 5% success rate in translating preclinical studies to effective clinical trials. This shift necessitates innovation in drug testing methodologies.
From Animal Models to “Brain on a Chip”
An Israeli startup, Itay and Beyond, in collaboration with institutions such as the Hadassah-University Medical Center in Jerusalem and Schneider Children’s Medical Center in Petah Tikva, is pioneering a groundbreaking approach. They have developed brain organoids and a 3D “brain on a chip.” This technology creates a more accurate, human-resemblant model to test and potentially repurpose existing drugs, offering a glimpse into a future where the development of drugs for neurodevelopmental disorders becomes both faster and more reliable.

Understanding the Complexity of the Human Brain Through Organoids
Brain organoids are cultured tissues grown in vitro, mimicking brain functions and allowing researchers to investigate nearly any aspect of brain physiology. The complexity of brain organoids provides an invaluable tool for exploring intricate neurological and psychiatric disorders such as autism spectrum disorder (ASD) and epilepsy, which have eluded effective treatment options until now.
Pro Tip: Using brain organoids allows for the ethical testing of drugs, reducing the reliance on animal models and potentially accelerating the drug development process.

Case Study: Tackling Autism Spectrum Disorder
Professor Liya Kerem, alongside Dr. Shirley Saar, is utilizing brain organoid technology to identify existing drugs capable of treating ASD. With over 75 million individuals affected globally, finding an effective treatment is of paramount importance. Recent studies show promising results, as these organoids can showcase the intricate dynamics of how certain drugs affect brain cells, potentially revolutionizing ASD treatment.
