About Wntresearch AB

WntResearch is developing a completely new type of drug with the potential to improve survival in cancer without giving rise to serious side effects.  Ad hoc observations from an ongoing phase 2 study in patients with colon cancer indicate that the Company's drug candidate Foxy-5 has a tumor suppressive effect already after three weeks of treatment. This means that Foxy-5 could counteract the ability of cancer cells to spread and invade healthy tissue, but also potentially eliminate cancer cells. The clinical study is now continuing with the aim of confirming these promising research findings. WntResearch then intends to establish partnerships with one or more international pharmaceutical companies ahead of the final part of the development and a global commercialization. WntResearch's shares are traded on Spotlight Stock Market. For more information, visit www.wntresearch.com.
