Vivesto AB products

Docetaxel micellar is a product candidate in early clinical development and is a novel formulation that combines XR-17 with docetaxel - a well-established cytotoxin, currently administered intravenously and containing ethanol. In June 2020, Vivesto partnered with the Swiss Group for Clinical Cancer Research (SAKK) with the aim of conducting the first clinical study on the treatment of metastasized prostate cancer with Vivesto’s Docetaxel micellar formulation. In June 2021 the first patient was dosed in an investigator-initiated Phase 1b clinical trial in patients with advanced prostate cancer. It is an open-label, multicenter, single-stage study conducted by SAKK at major hospitals in Switzerland, recruiting 18 chemotherapy-naïve patients with metastatic castration resistant prostate cancer (mCRPC) with adequate bone marrow, liver and renal function.

Cantrixil is a product candidate in clinical stage being developed for the treatment of ovarian cancer. Cantrixil consists of the active molecule, a potent and selective third generation benzopyran SMETI inhibitor named TRXE-002-01, encapsulated in a cyclodextrin. It is believed to target a wide spectrum of cancer cells, including chemotherapy-resistant tumor-initiating cells that are thought to be responsible for disease relapse. In December 2020, top-line results of a Phase I open-label study (NCT02903771), conducted at sites in the USA and Australia, were released. The Phase I study met its primary endpoints, establishing clinical proof of concept, subject to further clinical evaluation and confirmation. The results from the Phase I study were published in Cancers, a peer reviewed, open access journal of oncology. A Phase II study with Cantrixil is expected to be initiated in the second half of 2022.
