A team of researchers at the Hebrew University of Yerushalayim has introduced a new technological approach with the potential to rapidly develop new drugs without the need for animal experiments.

The primary animals used in drug development are rodents, with different genetics, physiology and metabolism than humans, leading to a situation where successful therapies in rodents often fail in clinical trials.

The HU project developed human-on-a-chip technology, using human tissues in a device, which mimics human physiology. While this type of technology has been in place for over thirty years, recent research incorporating microscopic sensors in the human tissue itself enabled the team to precisely monitor the body’s response to specific drug treatments.

“Drug development is a long and expensive endeavor that is defined by multiple failures. The main reason for this failure is that clinical experiments are ultimately based on minimal information gained from animal experiment which often fail to replicate the human response,” said Professor Yaakov Nahmias, director of the Grass Center for Bioengineering and founder of Tissue Dynamic, who led the research team.

“What makes our technology unique is that it allows us to go beyond what was ever possible with animal experimentation. We are now able to insert microsensors that offer us real time information on how drugs work and when they stop working,” Professor Nahmias says.

Utilizing this new technology, the researchers were able to show that a commonly used cancer drug, cisplatin, causes a dangerous buildup of fat in human kidneys. They were then able to combine this chemotherapy with a different drug, empagliflozin (Jardiance), designed to limit the absorption of sugar in the kidneys, to reduce the fatty buildup damage and minimize the kidney damage experienced by cancer patients during therapy.

This application represented the first time that the bionic chip was used to develop a drug protocol while avoiding the traditional dependence on animal testing.

“This groundbreaking technology has the potential to significantly reduce the testing and production time for drugs while also avoiding the need to test animals in the lab. This will save time, money and certainly unnecessary suffering. Our company Tissue Dynamic continues to develop innovative tools to aid in drug development and we are now moving ahead with clinical testing and working towards regulatory approval of specific drugs as a new way to treat cancer.”
