90% of people who die from cancer respond well to the first treatment, but the cancer is fatal upon its return. In these cases, the tumor has often become resistant to the treatment that initially worked. PERSIST-SEQ, a new international consortium of academic and industry experts in cancer research, will spend the next 5 years intensively investigating why cancer often returns after treatment. The consortium is led by Oncode Institute and AstraZeneca; program management and communication are coordinated by Lygature. The funding of 7 million euros is provided by the European Innovative Medicines Initiative (IMI).

Therapy resistance is one of the leading causes of cancer deaths and is clinically difficult to predict, prevent or treat. Although resistance has been studied extensively in recent decades, it is still unclear how it arises at the cellular level. “Why does cancer come back after treatment and why does it often come back worse? Using single-cell sequencing and organoid technology, we can answer this question at the cellular level,” says Principal Investigator Alexander van Oudenaarden (Hubrecht Institute and Oncode Institute). "We hope to explain why cancer reappears in different tissue types after treatment and why the reappeared tumor cells grow faster." The ambition of Oncode Institute is to test treatment inventions as quickly as possible in patients who could potentially benefit from new treatments.

This initiative is based on two innovative technologies with roots in leading Dutch laboratories: single-cell sequencing and organoids. With single-cell sequencing, genetic information can be mapped for individual cells. The combination with organoid technology makes it possible to do this in the context of a mini-organ or mini-tumor, grown from patient tissue. With this combination, the consortium will map the genetic pattern of 5 million individual cancer cells over the next 5 years. The ultimate goal is to develop new cancer treatments based on these data and to prevent therapy resistance.

Broad collaboration
PERSIST-SEQ is a public-private partnership between universities, small and medium-sized biotechnology companies and large international pharmaceutical companies. “I am very excited to be part of this consortium”, says Van Oudenaarden. “Not only because of the importance of understanding therapy resistance, I am also sure that all partners will learn a lot from each other and thus each other and help further the joint fight against cancer."

Geert Kops, Head of Oncode Institute, says: “This consortium perfectly matches the goal of Oncode Institute to outsmart cancer and impact lives. We will be able to support the research in terms of science, technology and valorization and we look forward to cooperate with many interesting partners to realize the ambitious scientific and technological goals.”
