“The results obtained provide essential information about the action of Cantrixil in combination with other anti-cancer drugs and gives good guidance in the continued preclinical evaluation and moving of the program towards clinical studies in hard-to-treat hematological cancer indications. An understanding of the effects of combinations is important since Cantrixil, as almost all other new cancer therapies, would be developed in the clinic and initially used when marketed in combination with other anti-cancer agents,” said Erik Kinnman, CEO of Vivesto.

The new preclinical data further strengthens previous positive results with Cantrixil, which has shown strong cytotoxic effects at low doses in cell lines derived from patients with hematological cancers. Furthermore, the data provide guidance to upcoming in vivo experiments, as well as towards clinical development. Specifically, the data adds input to the dosing selection and regime in the planning of the next set of experiments, which will include in vivo hematological cancer models and patient sample testing.

About Cantrixil

Cantrixil is a drug candidate in development for the treatment of advanced cancer. Based on recently reported data and in order to maximize the commercial potential of the Cantrixil program, Vivesto has decided to focus further development on hematological cancer after having obtained results showing strong cytotoxic effects at low doses in cell lines from patients with hematological cancers. Cantrixil consists of the active molecule TRX-E-002-1, a selective third generation benzopyran and a potent tubulin polymerization inhibitor. Positive in vitro preclinical data from so-called ADME studies (absorption, distribution, metabolism and excretion) and secondary pharmacology studies presented in December 2023 confirm that Cantrixil has appropriate physicochemical properties and an acceptable safety profile with minimal "off-target" effects.
