Solna, Sweden, November 4, 2025 – Vivesto AB, an oncology-focused development company, today announced that positive results were obtained from preclinical studies in an animal model of Acute Myeloid Leukemia (AML), in which Cantrixil was combined with drugs used in standard of care treatments. Vivesto also announced that a new international patent application covering the treatment of hematological cancer with Cantrixil in combination with other treatments has been filed, with the potential to significantly strengthen the IP position.
The drug candidate Cantrixil has been evaluated in vivo in combination with other anti-cancer drugs in an animal model involving difficult to treat human AML cancer. The results demonstrate clear positive effects of Cantrixil alone and even stronger effects when Cantrixil was combined with other anti-cancer drugs. These positive results confirm previous preclinical in vitro and in vivo efficacy data that have shown strong effects of Cantrixil alone and synergistic effects when combined with standard of care treatments, and support continued development of Cantrixil in hematological cancer, especially in AML.
“Hematological cancer is one of Vivesto's priority focus areas, and we are pleased to report successful results from yet another preclinical study supporting further development of the Cantrixil program. The next steps involve further pre-clinical studies ahead of moving the program into clinical development,” said Erik Kinnman, CEO of Vivesto. “Vivesto also filed a new international patent application for the treatment of hematological cancer with Cantrixil that may further increase the value of the program.”
Vivesto is continuing the planning of activities needed to bring Cantrixil into clinical trials, and in parallel will investigate opportunities to partner the project to optimize the development program.
