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. The primary objective of this trial is to determine the maximum tolerated dose of Docetaxel micellar in patients with mCRPC and the secondary objectives are to evaluate safety, assess the preliminary anti-tumor activity, and to characterize the pharmacokinetics in this population.
